1 INTRODUCTION
1.1 Complaints by Canada and Mexico
1.1. This compliance dispute concerns the challenges by Canada and Mexico of the measure taken
by the United States in 2013 to comply with the Dispute Settlement Body (DSB) recommendations
and rulings in United States – Certain Country of Origin Labelling (COOL) Requirements (DS384
and DS386).
1
1.2. On 10 June 2013, Canada and Mexico reached an understanding with the United States in
"Agreed Procedures under Articles 21 and 22 of the Dispute Settlement Understanding"
(Sequencing Agreement).2 According to paragraph 2 of this Sequencing Agreement, Canada and
Mexico were not required to hold consultations with the United States before requesting the
establishment of a panel under Article 21.5 of the Understanding on Rules and Procedures
Governing the Settlement of Disputes (DSU).
1.2 Panel establishment and composition
1.3. On 19 August 2013, Canada and Mexico requ ested the establishment of a panel pursuant to
Articles 6 and 21.5 of the DSU, Article 14 of the TBT Agreement, and Article XXIII of the
GATT 1994, with standard terms of reference as set out in Article 7.1 of the DSU.
3
1.4. At its meeting on 25 September 2013, the DSB referred this dispute to the original panel if
possible, in accordance with Article 21.5 of the DSU.
1.5. The Panel's terms of reference are the following:
To examine, in the light of the relevant pr ovisions of the covered agreements cited by
the parties to the dispute, the matter refe rred to the DSB by Canada in document
WT/DS384/26 and by Mexico in document WT/DS386/25, and to make such findings
as will assist the DSB in making the recommendations or in giving the rulings provided
for in those agreements.
1.6. In accordance with Article 21.5 of the DS U, the Panel was composed on 27 September 2013
as follows:
Chairperson: Mr Christian Häberli

 Members: Mr Manzoor Ahmad
 Mr João Magalhães

1.7. Australia; Brazil; Canada (for DS386); China; Colombia; the European Union; Guatemala;
India; Japan; the Republic of Korea; Mexico (for DS384); and New Zealand reserved their rights to
participate in the Panel proceedings as third parties.
1.3 Panel proceedings
1.3.1 General
1.8. Taking into account the United States' letter of 10 October 2013 and after consultation with
the parties, the Panel Working Procedures
4 and timetable were adopted on 28 October 2013. After
further consulting the parties, the Panel revised its Working Procedures on 21 January 2014 and
its timetable on 5 March 2014.

4 See the Panel Working Procedures (as revised on 21 January 2014) in Annexes A-1 and A-2.
WT/DS384/RW • WT/DS386/RW

1.9. The substantive meeting with the partie s was held on 18 and 19 February 2014. A session
with the third parties took place on 19 February 2014. On 10 April 2014, the descriptive part of the
Panel Reports was issued to the parties. The Interim Reports were issued to the parties on
27 June 2014. The Final Reports were issued to the parties on 29 July 2014.
1.3.2 Procedures for an open substantive meeting
1.10. At the organizational meeting held on 18 October 2013, Canada and the United States
requested, and the Panel agreed, that the substant ive meeting would be open to public viewing.
Mexico did not object to open hearings for these proceedings specifically, without prejudice to its
systemic views on open hearings. The parties proposed additional procedures for an open
substantive meeting. The Panel took into account the joint proposals received from the parties,
and adopted additional procedures for an open substantive meeting on 28 October 2013, which
were revised on 21 January 2014. These procedures provided for public viewing by means of
simultaneous closed-circuit television broadcasting of the substantive meeting to a separate room.
Closed sessions were foreseen for the parties to address business confidential information and for
those third parties that had requested not to make their statements public.
5
1.3.3 Procedures to protect Business Confidential Information (BCI)
1.11. At the organisational meeting on 18 October 2013, the parties agreed to submit proposals
for additional procedures to protect BCI. On 28 October 2013, additional procedures to protect BCI
were adopted, which took into account the joint proposal received from the parties.6
1.3.4 Procedures and Reports for DS384 and DS386
1.12. At the organizational meeting of 18 October 2013, the United States stated that the DSB
had not established a single panel pursuant to Article 9.1 of the DSU, and expressed that the
United States would be amenable to having two panels with harmonized procedures and
timetables in accordance with Article 9.3 of the DSU. The United States requested that separate
but harmonized Working Procedures be adopted for the compliance proceedings in DS384 and
DS386.
1.13. After having consulted the complainants, separate but substantively identical versions of the
Working Procedures, as well as additional procedur es to protect BCI and additional procedures for
an open substantive meeting, were adopted on 28 October 2013. In addition, on the same date,
a single joint timetable was adopted for DS384 and DS386.
1.14. At the substantive meeting on 18 and 19 February 2014, the parties were asked whether
they objected to including the Panel Reports in a single document with the understanding that,
following the same approach as in the original dispute, the final sections on Conclusions and
Recommendations would be printed on separate pages with the relevant DS symbol. The parties
did not object to this. In light of this, the Panel did not consider further the issue raised by the
United States under Article 9 of the DSU.
1.3.5 Request for enhanced third-party rights
1.15. In its third-party written submission of 2 December 2013, the European Union requested
certain enhanced third-party rights, namely that:
third parties be permitted to be present throughout the hearing; third parties should
be permitted to comment, at the invitation of the Panel, on matters arising during the
hearing; third parties should receive copies of any questions to the parties, their
responses and comments, and be permitted to comment thereon; and third parties

5 See additional procedures for an open substantive meeting in Annexes A-3 and A-4.
6 See additional procedures to protect BCI in Annex A-5 and A-6.
WT/DS384/RW • WT/DS386/RW

should similarly be permitted to be present at any subsequent meeting of the
compliance Panel with the parties.7
1.16. After consulting the parties, on 21 Janu ary 2014 the Panel granted the following enhanced
rights to all third parties:
a. the right to be present during the entirety of the substantive meeting of the Panel;
b. the right in the substantive meeting to ask ques tions, at the invitation of the Panel, to
the parties or the other third parties without any obligation to respond on the part of
parties or other third parties; and
c. access to the Panel's written questions to the parties and each party's written answers to
questions after the substantive meeting of the Panel.

Canadian cattle and hogs as well as imported Mexican cattle, which are used in the United States
to produce beef and pork, commodities covered by the amended COOL measure.

3 PARTIES' REQUESTS FOR FINDINGS AND RECOMMENDATIONS
3.1. Canada and Mexico request that the Panel find that the United States has failed to comply
with the recommendations and rulings adopted by the DSB on 23 July 2012 on the basis that the
amended COOL measure violates Articles 2.1 and 2.2 of the TBT Agreement and Article III:4 of the
GATT 1994. Canada and Mexico also request that the Panel find that the amended COOL measure
nullifies or impairs benefits accruing to Canada and Mexico within the meaning of Article XXIII:1(b)
of the GATT 1994.

3.2. The United States requests that the claims made by Canada and Mexico be rejected in their
entirety and that the complainants' claims under Article XXIII:(1)(b) of the GATT 1994 be found to
be outside the terms of reference of this Panel.
4 ARGUMENTS OF THE PARTIES
4.1. The arguments of the parties are reflected in their executive summaries provided to the Panel
in accordance with paragraph 18 of the Panel Working Procedures.10
5 ARGUMENTS OF THE THIRD PARTIES
5.1. The arguments of the third parties are reflec ted in their executive summaries provided to the
Panel in accordance with paragraph 18 of the Panel Working Procedures. 11 Australia and
Guatemala did not submit written or oral statements to the Panel.
6 INTERIM REVIEW
6.1. On 27 June 2014, the Panel submitted its Interim Reports to the parties. On 8 July 2014,
Canada, Mexico, and the United States each submitted written requests for the review of precise
aspects of the Interim Reports pursuant to Article 15.2 of the DSU.
12 On 15 July 2014, Canada,
Mexico, and the United States submitted written comments on each other's requests for interim
review. No party requested an additional meeting with the Panel on the issues identified in the
written comments.
6.2. In accordance with Article 15.3 of the DSU, this section of the Panel Reports sets out the
Panel's response to the requests and comments made at the interim review stage. The Panel
modified aspects of its Reports in light of the parties' interim review requests and comments where
it considered it appropriate to do so, as expl ained below. Section and paragraph numbers are the
same in the Interim and Final Reports. References to footnotes in this section relate to the Interim
Reports, except as otherwise indicated.
6.3. In addition to the modifications specified below, the Panel also corrected a number of
typographical and other non-substantive errors throughout the Reports, including those specified
by the parties.
6.4. In issuing its Interim Reports on 27 June 2014, the Panel requested the parties to identify
any business confidential information which the Interim Reports or its annexes may contain, and
which the parties wish to be redacted from the Final Reports. The parties did not identify any such
information in their requests for interim review. In accordance with its additional procedures to
protect BCI, on 29 July 2014 the Panel further requested the parties to confirm that the
Final Reports and its annexes do not contain any BCI.
6.5. In its aforementioned communication to the parties dated 27 June 2014, the Panel also noted
that it had received unsolicited follow-up comments by the parties on comments on the draft
descriptive part of the Panel Reports sent to the parties on 10 April 2014.
13 The Panel invited each
party to indicate in its requests for interim review whether its unsolicited comments on the draft
descriptive part of the Reports should be considered by the Panel as interim review comments.
In response, Canada noted that since the descriptive part had become part of the Interim Reports,
Canada sees no reason for the Panel to consider the unsolicited follow-up communications as part
of the interim review. Mexico did not object to the unsolicited follow-up comments on the
descriptive part not being incorporated in the in terim review. At the same time, Mexico suggested

10 See executive summaries of the parties' arguments, Annexes B1-B3.
11 See executive summaries of the third parties' arguments, Annexes C1-C8.
12 The Panel notes that, despite the 5.00 p.m. (Geneva time) deadline on 8 June 2014 for parties'
interim review requests, the United States submitted the electronic copy of its interim review request at 6.53
p.m. on 8 June, and the hard copy version at 10.10 a.m. the following day.
13 In particular, on 24 April 2014 Canada and Mexico submitted unsolicited follow-up comments on the
United States' comments of 23 April 2014. The United States responded to these with unsolicited follow-up
comments on 12 May 2014. Finally, on 14 May 2014 Mexico submitted additional unsolicited comments.
Most of these comments concerned the elements of the measure at issue, in particular the COOL statute.
WT/DS384/RW • WT/DS386/RW

that comments on the descriptive part be incorporated into the final report, provided that inclusion
does not affect the date of the issuance of final report to the parties. The United States did not
respond to the Panel's invitation. In light of the above, the Panel left the descriptive part of its
Interim Reports unchanged, and did not incorporate the parties' unsolicited comments on the
descriptive part into its interim review.
6.6. Canada suggested revising paragraph 7.18 to reflect that there are instances where the
place of occurrence of a production step can be omitted. The United States did not support
Canada's requested insertion of the phrase "subject to certain flexibilities" and considered the
Panel's statement to be accurate. In light of the parties' comments, the Panel added the word
"generally" to paragraph 7.18 in reference to the amended COOL measure's point-of-production
labelling.
6.7. Canada objected to the characterization of its position in footnote 52 (footnote 68 in the
Final Reports) to paragraph 7.18 and contends that it did not concede the accuracy of
reference to a "single label". Conversely, the United States asserted that the Panel did not
mischaracterize Canada's position, and considered the Panel to have correctly cited Canada's
written submission. In light of the parties' comments, the Panel adjusted the latter part of
footnote 52 (footnote 68 in the Final Reports) to paragraph 7.18 regarding Canada's position as to
the establishment of a "single label".
6.8. Canada pointed out that the description in paragraph 7.28 of the definition of "retailer"
under the Perishable Agricultural Commodities Act of 1930 omitted the exclusion of entities that do
not ship, receive, or contract to be shipped or receive perishable agricultural commodities in
quantities exceeding 2,000 pounds (one ton) in a single day. The Panel supplemented footnote 72
(footnote 88 in the Final Reports) to paragraph 7.28 with respect to the definition of "retailer"
under PACA.
6.9. The United States requested that the Panel delete the references to "commingled covered
commodities" from paragraphs 7.33 and 7.34 and from footnotes 85, 90, and 257
(footnotes 101, 206, and 275 in the Final Reports) . According to the United States, the
commingling flexibility for meat was set forth in § 65.300(e) of the 2009 Final Rule, whereas
§ 65.300(g) of the 2009 Final Rule "define[s]" the term "commingled covered commodities" only in
regard to "perishable agricultural commodities", which exclude meat products. Canada objected to
the United States' request. According to Canada, instead of a definition of any kind, § 65.300(g)
sets out labelling rules; the term "commingled covered commodities" is defined in § 65.125.
6.10. The Panel declines the United States' request. The Panel notes that § 65.300(g) of the 2009
Final Rule does not define the term "commingled covered commodities". As noted in footnote 85
(footnote 101 in the Final Reports) to paragrap h 7.33, that term is defined in the unamended
§ 65.125 of the 2009 Final Rule without any dist inction between different types of "covered
commodities" as follows: "covered commodities (of the same type) presented for retail sale in a
consumer package that have been prepared from raw material sources having different origins."
In turn, §§ 65.300(e) and (g) set forth different labelling rules for commingled meat products and
commingled perishable agricultural commodities. In addition, in introducing the term "commingled
covered commodities", paragraph 7.33 explains that the amended COOL measure "defin[es]
'covered commodities' in relevant part as '[m]uscle cuts of beef and pork' and '[g]round beef …
and ground pork'." (emphasis added) As indicated in section 7.3.2.1, the Panel's review of the
amended COOL measure is limited to the products at issue identified in paragraphs 2.2 and 7.26 of
the Reports.
6.11. The United States commented that in s ections 7.3.3.3 (paragraphs 7.38-7.43) and
7.3.4 (paragraph 7.44 and Table 2), as well as paragraph 7.108 the Panel "appear[s] to
conclude that in the improbable case where an animal is imported for immediate slaughter after
spending time in two different countries, the 2013 Final Rule would not allow similar flexibility in
listing the country of raising as is the case under the B Label." The United States requested
alteration in light of its arguments provided in response to the Panel's questions. Canada
commented that the issue raised by the United States is addressed in paragraphs 7.245-7.254 and
that the alteration of these sections proposed by the United States is thus unwarranted. Canada
further stated that paragraph 7.108 simply summarizes the rules under the amended COOL
measure that apply to Category C muscle cuts, and that there is no need to modify the paragraph
as suggested by the United States.
WT/DS384/RW • WT/DS386/RW

6.12. The Panel declines the United States' request. Section 7.3.3.3 describes the amended
multiple countries of raising flexibility under the amended COOL measure. Section 7.3.4 simply
sets out label variations in light of the flexibilities under the original and amended COOL measures.
The specific point raised by the United States regarding Label C is discussed in
paragraphs 7.107-7.110, 7.245-7.254, and again in 7.351. In these paragraphs, the Panel outlines
the parties' disagreement as well as the relevant provisions of the COOL statute and 2013 Final
Rule. Further, the Panel examines the parties' competing interpretations, including their arguments
provided in response to the Panel's questions, and the labelling implications for both scenarios as
depicted in Tables 9 and 14. As the United States' position is already reflected in these
paragraphs, no further changes were considered necessary.
6.13. Canada suggested that the description of Label B in paragraph 7.42 reflect the country
order flexibility that existed under the 2009 Final Rule. In this respect, the United States
suggested replacing the word "would" with "could". The Panel adjusted the relevant portion of
paragraph 7.42 in light of the parties' comments.
6.14. In regard to paragraph 7.117 and Table 10, Canada argued that non-commingled muscle
cuts derived from Category C animals were not eligible for Label B ("Product of the United States,
Canada") under the 2009 Final Rule. Conversely, the United States argued that the Reports
already address Canada's request in paragraph 7.114 and footnote 268 (footnote 284 in the
Final Reports). Although the Reports address Cana da's request in footnote 268 (footnote 284 in
the Final Reports) to paragraph 7.114, for greater accuracy the Panel deleted the word "or" and
"Product of U.S., Canada" from both paragraph 7.117 and Table 10. The Panel also made
consequential adjustments to footnote 269 (footnote 285 in the Final Reports) and to the Note to
Table 10.
6.15. Canada argued that the statement that "many operators in the United States commingled"
in the second sentence of paragraph 7.121 s h o u l d n o t b e a t t r i b u t e d t o C a n a d a a s i t w a s n o t
supported by the relevant reference in footnote 271. The United States considers that the Panel
did not mischaracterise Canada's position on commingling. In light of the passages referenced in
footnote 271, the Panel split the second sentence of paragraph 7.121 into two sentences.
In addition, the Panel adjusted the final sentence of the same paragraph accordingly.
6.16. Canada requested that the word "survey" in paragraph 7.124 be replaced with a less
comprehensive term for referencing the public consultation process conducted by the USDA before
adopting the 2013 Final Rule. The United States also considered the word "survey" to be
inaccurate, and suggested replacing "survey conducted by the USDA" with "responses received to
the proposed rule". The Panel has replaced the word "survey" with "comments the USDA received
on the proposed 2013 Final Rule" in paragraph 7.124.
6.17. Additionally, the United States requested that a sentence in paragraph 7.124 referencing
the American Meat Institute's comments on the proposed 2013 Final Rule be relegated to a
footnote and adjusted so as to avoid the suggestion that evidence on slaughter facilities processing
"mixed-origin" livestock demonstrates commingling. According to the United States, these
slaughterhouses could have processed B or C category animals without commingling. Conversely,
Mexico noted that the American Meat Institute's comments use the term "mixed-origin" to refer to
animals born in different countries and processed in the United States. Canada also objected to the
United States' request.
6.18. The Panel declines the United States' request. The American Meat Institute's comments of
April 2013 include a section entitled "The Meat Industry Utilizes the Current Rule's Practice of
Commingling and Prohibiting that Practice Will Impose Significant Costs not Considered by AMS".
Within this section, the comments state that "AMS seems to ignore the fact that commingling
occurs regularly and that the Category B label is used in the marketplace."
14 The rest of the
section attempts to quantify commingling and the impact of its elimination under the proposed
2013 Final Rule. In this context, immediately after the sentence stating that "[t]here are at least
15 large cattle slaughter plants that process mixed origin livestock and at least 6 such hog

14 Exhibit CDA-23, p. 3.
WT/DS384/RW • WT/DS386/RW

slaughter facilities", the comments address the economic impact of "the loss of commingling"
under the proposed 2013 Final Rule.15
6.19. The United States suggested adjusting paragraph 7.125 to reflect more accurately its
arguments on the percentages of commingling in th e US meat industry as presented by the USDA
in the 2013 Final Rule. In particular, the United States suggested inserting a sentence on how the
USDA came to its estimates. Mexico objected to this suggested new sentence, arguing that the
United States has not explained why it is necessary or appropriate.
6.20. The Panel notes that the new sentence suggested by the United States is similar to the
sentence in a paragraph of the United States' first written submission already referenced in
footnote 288 (footnote 304 in the Final Reports) to paragraph 7.125. Accordingly, the Panel
declines the United States' suggestion to insert this sentence. As for the existing first sentence of
the paragraph, the Panel made editorial changes in light of the United States' suggestions, while
leaving footnote 288 (footnote 304 in the Final Reports) unchanged.
6.21. With regard to paragraphs 7.128-7.132 and Table 12 , Canada did not agree that, in
practice, the 2013 Final Rule amended the coverage of Label D. In particular, Canada contends
that the origin of Category D meat products under the 2009 Final Rule was determined based on
the country of slaughter. Thus, according to Canada, "in practice, under the 2009 Final Rule,
covered muscle [cut] commodities imported from Canada and derived from animals that
underwent production steps in the United States were required to be labelled as 'Product of
Canada'." Canada further contends that the United States undertook no extraterritorial verification
of the life histories of animals used to produce imported muscle cut covered commodities, and that
Canada does not maintain records that would allow retailers to demonstrate that an imported
muscle cut commodity was derived from an animal th at underwent a production step in the United
States. Referring to Table 12, Canada thus asserts that, in practice, "Label D applied in scenarios
D2, D3, and D4 under the original COOL measure." The United States commented that, as the
2009 Final Rule was written, Category D meat imported into the United States would be derived
from animals that were not born, raised, or sl aughtered in the United States. However, under
customs rules, Category D meat would receive a country of origin designation from the country
where the meat was slaughtered (substantially transformed).
6.22. The Panel declines to make any modifications to paragraphs 7.128-7.132 and Table 12.
Canada's comments concern whether the 2013 Final Rule amended the coverage of Label D "in
practice". As noted in the Panel's findings in paragraph 7.15, Category D origin is designated
according to substantial transformation under both the 2009 and 2013 Final Rules. The amended
terms of coverage introduced by the 2013 Final Rule are set out in paragraphs 7.15 and 7.128.
16
The evidence of the practical likelihood of Scen arios D2, D3, and D4 in Table 12 is addressed in
paragraph 7.279. Although Canada's comments concern Label D coverage "in practice" under the
original and amended COOL measures, Canada does not dispute the textual amendments
introduced by the 2013 Final Rule. Nor does Ca nada address the absence of evidence that
Scenarios D2, D3, or D4 ever occurred "in practice" under the original COOL measure. Canada's
allegation that such origin scenarios would not have been detectable, or distinguishable from
Scenario D1, would only be relevant if such scenarios were shown to occur. Even if this allegation
were to be substantiated by evidence regarding the treatment of imported muscle cuts "in
practice", the explicit terms of the original an d of the amended COOL measures should not be
ignored. As the Reports reflected the relevant de jure and de facto considerations with respect to
Label D under the original and amended COOL me asures, the Panel did not consider any changes
to be necessary.
6.23. The United States suggested that paragraph 7.135 also address the evidence submitted
by the United States on the lack of a material impact from the 2013 Final Rule on large processors,
such as Tyson Foods. The complainants objected to the United States' request. Canada argued
that the evidence shows one company's slight incr ease in beef sales over a three-year period,
measured in value, which has no direct relevance for the impact of the 2013 Final Rule.
Both complainants noted that the evidence in question relates to Tyson Foods' annual reports for

15 Exhibit CDA-23, p. 6.
16 As observed by the Appellate Body, under the original COOL measure, "Category D meat derives from
animals not born, raised, or slaughtered in the United States." Appellate Body Reports, US – COOL, para. 333.
WT/DS384/RW • WT/DS386/RW

the fiscal years ending in October 2011, Septem ber 2012, and September 2013, the last of which
ended in September 2013, two months before the end of the six-month adjustment period under
the 2013 Final Rule. Canada added that other exhibi ts cited in the Reports containing statements
from Tyson Foods address more directly the impact of the 2013 Final Rule.
6.24. The Panel considers that other exhibits referenced in the Reports, including in paragraph
7.135, in particular Exhibits CDA-25, CDA-42 (BCI), and CDA-70, more directly address the
amended COOL measure's impact on the operations of Tyson Foods than the evidence referenced
by the United States. In fact, these exhibits di rectly reflect Tyson Foods' views about the 2013
Final Rule before its adoption, and how Tyson Foods changed its sourcing policy following the 2013
Final Rule's entry into force. Accordingly, the Panel declines the United States' request and leaves
paragraph 7.135 unchanged.
6.25. The United States requested supplementing the findings in sections 7.5.4.1.2.4
(paragraphs 7.138-7.150) and 7.5. 4.2.4.1 (paragraphs 7.220-7.221) to include certain
arguments made in its written submissions. Canada considered that the United States' arguments
regarding the impact of the amended COOL measur e on recordkeeping requirements were already
addressed in the Panel's assessment.
6.26. The Panel declines the United States' request. Section 7.5.4.1.2.4 outlines the correlation
between the nature of the origin claim and th e recordkeeping requirements under the amended
COOL measure. This covers the substance of the arguments referred to by the United States in its
comments, including its reference to the Appellate Body's reasoning in the original dispute.
In particular, relevant Appellate Body statements are reproduced in paragraph 7.142 and further
addressed in footnote 324 (footnote 340 in the Final Reports). Therefore, the alterations requested
by the United States were not considered necessary.
6.27. The United States considered the Panel's reference in paragraphs 7.146-7.149 to
"'augmentation of the records' to apparently me an the inclusion of 'additional information to a
firm's bills of lading, invoices, or other records associated with movement of covered commodities
from purchase to sale'." (quoting the 2009 Final Rule, p. 2699). With regard to the conclusion in
paragraph 7.149, the United States submitted that it "does not see the logic in equating adding
[sic] additional information to a bill of lading to the increase in a recordkeeping 'burden'". Canada
commented that the Panel's conclusion is supported by an analysis that considers a broad range of
factors extending beyond the impact of additional information added to bills of lading. Likewise,
Mexico commented that the finding is not based exclusively on information requirements for bills
of lading, and that the Panel cites other evidence in support of the conclusion in paragraph 7.149.
6.28. The Panel declines the United States' request. The only reference to additional information
on a firm's bills of lading is found in footnote 338 (footnote 354 in the Final Reports) as part of a
long passage cited from the USDA that eviden ces the dynamic between greater information on
labels and more upstream records. The conclu sion in paragraph 7.149 draws heavily upon
preceding paragraphs and the Panel's findings with respect to greater label variety and segregation
under the amended COOL measure.
6.29. The United States commented that paragraph 7.148 contained a "partial quotation" from
the 2009 Final Rule that "may misleadingly exaggera te the role of segregation as a cost driver",
and suggested additions of the complete quotation. Canada commented that the major cost
drivers are noted as including segregation when firms are not using a multiple-origin label. Canada
therefore considered that there was no need to include the additions to the excerpt from the 2009
Final Rule set out in this paragraph. Mexico considered that the proposed expansion of the
quotation would make the paragraph as a whole confusing, and that the United States' concern
could be addressed by adding the words "inter alia".
WT/DS384/RW • WT/DS386/RW

6.30. The Panel cited the USDA's reference to "the major cost drivers" of the 2009 Final Rule as
"including" scenarios of segregation without commingling. The Panel did not consider this citation
to distort the USDA's statement, which is cited in combination with another statement made by the
USDA to a similar effect in footnote 340 (footnote 356 in the Final Reports). In light of the parties'
comments, the Panel added " inter alia " to paragraph 7.148 and "or products" in footnote 340
(footnote 356 in the Final Reports).
6.31. The United States requested revision of paragraph 7.149 to include its argument that
recordkeeping has not changed and that "the amended COOL measure simply implements the
Appellate Body recommendations that the information already maintained by upstream producers,
be conveyed to consumers through more detailed labelling." Canada commented that this
paragraph summarizes the Panel's conclusions after assessing the arguments of the parties and
the evidence before it. In Canada's view, the repe tition of US arguments is inappropriate in this
context. Mexico similarly considered that the United States' arguments are already reflected, and
that its request is improper for interim review as it would alter the Panel's findings by
incorporating the United States' arguments into the Panel's conclusions.
6.32. The Panel declines the United States' request. Paragraph 7.149 summarizes the
Panel's conclusions with respect to the recordke eping burden under the amended COOL measure.
The United States' arguments are reflected in the preceding paragraphs, and relevant Appellate
Body statements are discussed in paragraph 7.142 and footnote 324 (footnote 340 in the Final
Reports). Inasmuch as the United States is reasserting that the recordkeeping provisions under
the original and amended COOL measures are form ally identical, paragraphs 7.138-7.139 explain
that the Panel's analysis focuses on whether in practice the amended COOL measure requires
greater recordkeeping under formally unchanged provisions. The Appellate Body has held that
Article 21.5 compliance panels may properly address "claims against measures taken to comply
that incorporate unchanged aspects of original measures"
17 as well as "new claims against
inseparable aspects of a measure taken to comply, which are unchanged from the original
measure".
18 Further, the Appellate Body has indica ted that, in the context of Article 21.5
proceedings, formally identical "wording" does not necessarily amount to challenged provisions
having identical "meaning"; rather, this latter may depend on the interaction of different aspects of
the measure under review.19
6.33. The United States suggested replacing the word "confirm" in the first sentence of
paragraph 7.162 with "assert in affidavits, but do not substantiate with specific evidence".
The complainants objected to the United States' request. Mexico argued that the United States' is
attempting to undermine the status of the eviden ce cited by the Panel. Canada pointed out that
two pieces of evidence cited in the first sentence of paragraph 7.162 should not be qualified as
affidavits as they are industry comments submitted to the USDA in its public comment exercise on
the proposed 2013 Final Rule.
6.34. The Panel notes that in essence the firs t sentence of paragraph 7.162 consists of two
citations from comments submitted by an industry participant to the USDA in its comments to the
proposed 2013 Final Rule. The footnote to the second citation also references comments from
another industry participant to the USDA as well as affidavits by Mexican industry participants.
Like the original panel, the Panel in this comp liance dispute considers affidavits by industry
participants as evidence that may be relied upon to reach or confirm findings. Accordingly, the
Panel declines the United States' request and leaves the first sentence of paragraph 7.162
unchanged.

17 Appellate Body Report, US – Zeroing (EC) (Article 21.5 – EC), para. 427.
18 Appellate Body Report, US – Zeroing (EC) (Article 21.5 – EC), para. 433.
19 More specifically, in US – Shrimp (Article 21.5 – Malaysia), the Appellate Body noted that "the
wording of Section 609 ha[d] not been changed since the first case" and went on to state that "[i]n addition,
the meaning of Section 609 ha[d] not been changed" in light of a court ruling addressing other aspects of the
challenged measure. Appellate Body Report, US – Shrimp (Article 21.5 – Malaysia), para. 93. The altered
meaning of formally identical provisions is consistent with the Appellate Body's consideration that "the relevant
facts bearing upon the 'measure taken to comply' may be different from the relevant facts relating to the
measure at issue in the original proceedings", and that "[i]t is natural, therefore, that the claims, arguments
and factual circumstances which are pertinent to the 'measure taken to comply' will not, necessarily, be the
same as those which were pertinent in the original dispute." Appellate Body Report, Canada – Aircraft
(Article 21.5 – Brazil), para. 41.
WT/DS384/RW • WT/DS386/RW

6.35. Canada pointed out that the section in the original US – COOL panel reports referenced in
footnote 378 (footnote 394 in the Fi nal Reports) to paragraph 7.166 focuses more on the
incentives arising from the measure than on the legal necessity of making a choice. The Panel has
left paragraph 7.166 unchanged. The relevant paragraphs of the original US – COOL panel
reports
20 referenced in footnote 378 (footnote 394 in the Final Reports), while also addressing the
issue of incentives, are entitled "[t]he legal necessity of making a choice" and specifically examine
Appellate Body guidance related to this issue.
6.36. The United States requested the Panel to adjust paragraph 7.184 to reflect more
accurately the objective of the Updated Sumner Econometric Study. The Panel has adjusted
paragraph 7.184 concerning the objective of the Updated Sumner Econometric Study. At the same
time, the Panel declines the United States' sugges ted addition to the last sentence of the same
paragraph concerning how the Panel evaluates the possible impact of the different factors that
may explain the evolution of livestock's price basis and import ratio.
6.37. Mexico requested additional references to its submissions in footnote 454 (footnote 470
in the Final Reports) to paragraph 7.200 . The Panel included additional references in footnote
454 (footnote 470 in the Final Reports) to paragraph 7.200 to Mexico's submissions.
6.38. With respect to footnote 467 (footnote 483 in the Final Reports) to
paragraph 7.203, Mexico recalled its arguments as to the distinction between three different
concepts, namely "detrimental impact", "relevant regulatory distinction(s)", and "facts and
circumstances related to the design and application of the relevant regulatory distinction(s)". The
Panel supplemented footnote 467 (footnote 483 in the Final Reports) to paragraph 7.203 in light of
Mexico's request.
6.39. According to Mexico, paragraphs 7.206-7.207 and 7.280 did not fully reflect Mexico's
argument regarding Label E. The United States countered that these paragraphs are focused on
expressing the Panel's findings rather than summa rizing the parties' arguments. The Panel revised
footnote 474 (footnote 490 in the Final Reports) to paragraph 7.206 in light of the parties'
comments to reproduce the complainants' arguments in greater detail. No further changes were
considered necessary.
6.40. The United States requested supplementation of paragraph 7.229 to reflect its arguments
that Label D "is typically, if not always, prod uced entirely within the exporting country and
including additional steps within the label would not provide additional origin information". Canada
commented that this paragraph sets out certain facts as well as the intended effect of the
amended COOL measure. Canada added that the arguments of the parties regarding Label D are
addressed elsewhere in the Reports. Mexico commented that the United States' proposed additions
inaccurately describe its own argument on the reasons for not requiring point-of-production
information on Label D. Mexico also questioned the United States' substantiation of its argument
and considered the statement in paragraph 7.229 to be fully accurate. The Panel added a citation
into footnote 521 (footnote 537 in the Final Reports) to paragraph 7.229 to cross-reference
paragraph 7.279, and inserted additional reference into footnote 611 (footnote 629 in the Final
Reports) to paragraph 7.279 to the United States' arguments.
6.41. The United States requested that paragraph 7.240 reflect its position "regarding the
potential that animals imported for immediate slaughter may become B label" that "such a
situation is economically unrealistic". Canada commented that the United States' position that the
situation referred to is "economically unrealistic" is without merit. Canada referred to evidence that
some Canadian livestock exporters are sending slaughter-weight animals to the United States for
short periods of feeding so that the animals qual ify for the Category B production stream. Mexico
commented that the United States' proposed addition would affect the coherence of the paragraph,
and took issue with the content of the United Stat es' proposal as seeking to have the Panel adopt
the United States' argument as its own.
6.42. In light of the parties' comments, the Pane l declines to make the changes requested by the
United States. Paragraph 7.240 sets out the relevant requirements of the amended COOL measure
in the context of the complainants' contentions regarding the flexibility for multiple countries of

20 Panel Reports, US – COOL, paras. 7.386-7.392.
WT/DS384/RW • WT/DS386/RW

raising. Immediately following this, the Panel describes in paragraph 7.241 the evidence and
arguments submitted by the parties regarding the ac tual amount of time imported feeder and fed
cattle spend in the United States, which includes reference to the evidence mentioned by Canada
in its interim review comments.
6.43. With respect to the average figures in paragraph 7.242, Canada pointed out that feeder
cattle imported into the United States can spend more than 68% of their lives outside the United
States. The Panel revised paragraph 7.242 by removing the phrase "as much as" and by inserting
a footnote to explain that feeder cattle may sp end an even greater amount of time outside the
United States.
6.44. Mexico requested the Panel to add a paragraph to its analysis in paragraphs 7.255-7.256
of the appearance and placement of labels in th e context of legitimate regulatory distinctions.
Mexico suggested that this new concluding paragraph should reflect Mexico's arguments that no
retailers complied with the 2013 Final Rule during the six-month adjustment period following the
Final Rule's entry into force in May 2013, and that some retailers still do not comply with it at this
stage. Mexico suggested that this new paragraph co nclude that "[t]he labels of those retailers do
not provide any point of production information." Likewise, Mexico requested an adjustment to the
Panel's analysis in paragraph 7.354 concerning the amended COOL measure's degree of
contribution. The United States objected to Mexico's request to insert a new paragraph on an issue
the United States considered "unrelated" to paragraphs 7.255-7.256. The United States also
suggested leaving paragraph 7.354 unchanged becaus e Mexico's proposed sentence concerns the
distinct issue of the amended COOL measure's enforcement.
6.45. The Panel notes that paragraph 7.8 addre ssed the entry into force of the 2013 Final Rule.
Footnote 25 (footnote 41 in the Final Reports) to the same paragraph explains that the six-month
adjustment period for the livestock and meat industry expired in November 2013. Nonetheless, for
the sake of completeness, the Panel has inserted a footnote at the end of paragraph 7.256
addressing Mexico's evidence of labels following the end of the six-month adjustment period. In
light of this, the Panel did not consider it ne cessary to adjust paragraph 7.354 and draw any
conclusion from the unspecified prevalence of non-compliance with the 2013 Final Rule following
the expiration of the six-month adjustment period.
6.46. Mexico commented with respect to paragraph 7.258 that it had identified alternative
sources of information for determining the share of beef products subject to the amended COOL
measure. The Panel supplemented footnote 574 (footnote 592 in the Final Reports) to
paragraph 7.258 to reflect Mexico's alternative sources regarding the share of beef products
subject to the amended COOL measure.
6.47. Canada commented on the figures in footnote 579 (footnote 597 in the Final Reports)
to paragraph 7.260 that the original panel did not make findings to suggest that the percentages
listed in this footnote were established facts. Conversely, the United States considered that the
footnote accurately reflects what is already on the record from the original panel proceedings.
The Panel modified footnote 579 (footnote 597 in the Final Reports) to paragraph 7.260 in light of
the parties' comments to cite the original panel reports in greater detail.
6.48. Canada and Mexico commented that the percentages referred to in paragraph 7.273
include all beef that is consumed in the United States, and not just muscle cuts. Likewise, the
United States supported revising the paragraph to refer to all "beef consumed in the
United States". The Panel adjusted paragraph 7.273 in light of the parties' comments.
6.49. Mexico argued that paragraph 7.298 does not fully reflect Mexico's arguments, in
particular Mexico's arguments in paragraphs 165-178 of its first written submission and in
paragraphs 95-109 of its second written submission, on why the amended COOL measure falls into
an exceptional situation where a comparative analysis of alternative measures would be redundant
for finding a violation of Article 2.2 of the TBT Ag reement. In addition, Mexico suggested adjusting
footnote 628 (footnote 646 in the Fi nal Reports) to paragraph 7.290 to also reference
paragraph 179 of Mexico's first written submission and paragraph 94 of Mexico's second written
submission. The United States objected to Mexico's requests, which – according to the
United States – are merely re-stating Mexico's arguments already addressed by the Panel.
WT/DS384/RW • WT/DS386/RW

6.50. The Panel declines Mexico's request concerning paragraph 7.298. Paragraphs 165-178 of
Mexico's first written submission contain sections entitled "The Relative Importance of the
Interests or Values Furthered by the Amended COOL Measure"; "The Degree of Contribution Made
by the Amended COOL Measure to the Legitimate Objective"; "The Trade-Restrictiveness of the
Amended COOL Measure"; "The Nature of the Risks at Issue and the Gravity of Consequences that
would Arise from Non-fulfilment of the Object ive"; and "Weighing and Balancing of Relevant
Factors Demonstrates that the Trade-Restrictiveness of the Amended COOL Measure is
Unnecessary". In the latter section, Mexico argues that:
[w]hen weighed and balanced in a holistic manner, it is clear from these factors that
the trade-restrictiveness of the Amended C OOL Measure is disproportionate to the
risks that non-fulfilment would create. The fact that the Amended COOL Measure
might make some contribution to the objective does not outweigh the other relevant
factors. Accordingly, the trade-restrictiveness of the Amended COOL Measure is
unnecessary and it is inconsistent with Article 2.2 of the TBT Agreement.
21
6.51. This assertion by Mexico does not explain why the amended COOL measure falls into the
exceptional situation where a comparative analysis of alternative measures would be redundant for
finding a violation of Article 2.2 of the TBT Agreement. As regards the factors addressed by Mexico
under the above-mentioned headers, the Panel addressed the relevance of each of these factors
for its Article 2.2 analysis and analysed each relevant factor in turn elsewhere in its Reports.
6.52. Paragraphs 95-109 of Mexico's second written submission include sections carrying similar
headers as the ones mentioned above. The key conclusion of these paragraphs
22 is almost
identical to the one cited from Mexico's first written submission above.
6.53. As regards Mexico's request concerning footnote 628 (footnote 646 in the Final Reports),
the Panel notes that paragraph 179 of Mexico's first written submission addresses how the
comparative analysis should be conducted, not whether it is necessary in the case of the amended
COOL measure. In turn, paragraph 94 of Mexico 's second written submission references the
Appellate Body's analysis of the original COOL measure's trade restrictiveness, and argues that a
relational analysis of the amended COOL measure (including of the "relative importance" of the
interests or values that it furthers) "will demonstrate" inconsistency with Article 2.2. As these
arguments do not address why the amended COOL measure represents an exceptional situation,
the Panel declines Mexico's request to adjust the footnote 628 (footnote 646 in the Final Reports)
to paragraph 7.290.
6.54. Mexico argued that paragraph 7.318 should not refer to compliance with the
DSB recommendations and rulings in the original dispute as the "primary" purpose of the 2013
Final Rule. In light of Mexico's request, the Panel has replaced the word "primarily" with "in part".
6.55. Canada commented that the percentages of coverage in paragraph 7.347 exaggerate the
degree to which the amended COOL measure fulfils its objectives because they include Labels D
and E. Canada accordingly requested revising the figures to correspond to the coverage of
Labels A-C. Mexico similarly requested revision of this paragraph to reflect the focus on
Labels A-C. The United States requested modifications so that the percentages refer to overall US
beef and pork consumption and adjustments to the wording of certain sentences. Canada did not
object to the United States' requests to refer to overall US beef and pork consumption or to delete
the words "muscle cuts" in this paragraph. Howe ver, Canada objected to the United States'
requested revisions with respect to the degree of contribution achieved by exempted products.
Mexico similarly opposed the United States' requests for rephrasing certain findings in this
paragraph. The United States opposed Canada's request to insert the statement that "Labels A-C
cover, at most, between 16.3% and 24.5% of all beef consumed in the United States". Similarly,
the United States did not support changes requested by Mexico regarding percentages for
Labels A-D and additional language with such percentages in paragraph. 7.348.
6.56. In light of the parties' comments, the Panel revised paragraph 7.347 and inserted a new
footnote explaining the beef and pork products re presented by these figures. The Panel notes that

21 Mexico's first written submission, para. 178.
22 Mexico's second written submission, para. 109.
WT/DS384/RW • WT/DS386/RW

the parties' data do not specify the proportion within Categories A-C that are labelled, as opposed
to those that are exempted from coverage. Thus, although muscle cuts in Categories A-D comprise
between 16.3% and 24.5% of US beef consumption, the proportion of exempted beef products
that are muscle cuts as opposed to ground beef cannot be precisely determined based on the data
provided by the parties. See also paragraph 7.258 below. The Panel further notes that, given the
United States' importation of beef muscle cuts in Category D, the share of US beef consumption of
muscle cuts in Categories A-C would be lower than 24.5%.
 As a final note, these ranges hinge on a
number of assumptions, including the share of US beef or pork consumption sold in retailers and in
food service establishments, as well as the share of processed food sold at (i) exempted retailers,
(ii) food service establishments, or (iii) retailers subject to the amended COOL measure. Different
values for these shares lead to different shares of beef or pork muscle cuts in relation to total US
beef or pork consumption that are subject to the amended COOL measure.
6.57. Mexico requested additional references to paragraphs of its written submissions to be
inserted into footnote 842 (footnote 861 in the Final Reports) to paragraph 7.373 .
The Panel supplemented footnote 842 (footnote 861 in the Final Reports) to paragraph 7.373 as
requested by Mexico.
6.58. Canada argued that the Panel's analysis of the risks non-fulfilment would create in
paragraphs 7.374-7.383 and 7.415-7.424 does not address Canada's arguments (i) that origin
information is a "credence attribute"; and (ii) that there would be "no harm" from consumers not
receiving information on production steps and hence "mak[ing] their purchasing decision on false
food safety assumptions."
6.59. The Panel declines Canada's request. In paragraph 7.379, the Panel explained that
reviewing the risks of non-fulfilment of the am ended COOL measure's objective under Article 2.2
of the TBT Agreement does not require defining any precise relationship with the relative
importance of the interests or values protected under Article XX of the GATT 1994. For its
Article 2.2 analysis of the amended COOL meas ure, the Panel therefore reviewed the risks
non-fulfilment of the amended COOL measure's obje ctive would create strictly from the viewpoint
of the objective, i.e. providing consumer information on origin. The Panel continues to consider it
unnecessary to address how this objective – or the consequences of its non-fulfilment –compares
with other objectives or values such as food sa fety. As regards the specific issue of "credence
attributes", the Panel notes that Canada references the USDA's analysis of possible credence
attributes in connection with market failure arguments; at the same time, Canada also argues that
"[t]he USDA has not explained what these 'latent attributes' might be, whether they actually exist
or why they may be important to certain consumers."
23 In any event, the Panel does not review
the risks non-fulfilment would create from a possible market failure perspective. As the Panel
recalled in paragraph 7.421, "[t]here are … circ umstances in which Members may decide to adopt
particular regulations even in the absence of a specific demand from their citizens, and may do so
without in fact shaping consumer expectations through regulatory intervention."
6.60. In regard to paragraphs 7.415-7.424, Canada argued that the Panel has an obligation to
make a finding on the "gravity of the consequences" in the context of its analysis under Article 2.2.
The United States was of the view that the Panel was very clear that, on the basis of the available
evidence, it could not reach a conclusion on this matter.
6.61. In the paragraphs mentioned by Canada as well as the sections preceding these
paragraphs, the Panel reviewed in detail the parties' evidence on the risks non-fulfilment would
create. In light of this analysis, in paragraph 7.423 the Panel concluded that "based on th[is]
evidence … [it] cannot ascertain the gravity of not fulfilling the amended COOL measure's
objective." As explained by the Appellate Body, panels may not "make affirmative findings that
lack a basis in the evidence contained in the panel record."
24 As a result, the Panel declines
Canada's request.
6.62. Canada requested the Panel to delete from paragraph 7.469 the reference to the
"Product of the U.S." label. The United States objected to Canada's request as Canada did not
formally disagree with the Panel's formulation of the "Product of the U.S." label in response to

23 See Canada's first written submission, paras. 145-146.
24 Appellate Body Report, US – Carbon Steel, para. 142.
WT/DS384/RW • WT/DS386/RW

Panel question No. 51. Furthermore, according to the United States, to the extent Canada argues
that the label under its first alternative measure would be identical to Label D, "Product of the
U.S." is an appropriate formulation of Labels A-C under the first alternative measure. In light of
Canada's request and the United States' comments, the Panel has adjusted the last sentence of
paragraph 7.469.
6.63. The United States requested that paragraph 7.489 be deleted because the parties did not
address how less origin information might reduce consumer confusion, and there is no evidence on
the record on this matter. Conversely, Canada co nsidered that paragraph 7.489 should be kept as
it sets out the Panel's reasoning similar to certain paragraphs in the Appellate Body Reports in the
original US – COOL dispute. Mexico also objected to the United States' request, arguing that there
is evidence on the record of labels that are difficult to understand.
6.64. The Panel considers paragraph 7.489 to be part of its reasoning on the first alternative
measure's degree of contribution to the objective of providing consumer information on origin.
The Panel has therefore maintained this paragraph.
6.65. In regard to paragraphs 7.491 and 7.503, Canada requested that the Panel complete the
analysis and determine that the first and second alternative measures, respectively, are
reasonably available and less-trade restrictive th an the amended COOL measure. Mexico made a
similar request in the context of paragraph 7.491 with regard to all four alternative measures.
Specifically, in regard to the third and fourth alternative measures, Mexico requested the Panel to
address the degree of contribution to the amended COOL measure's objective. The United States
objected to the complainants' requests. The Unit ed States argued that the Panel addressed the
first two alternative measures' degrees of contribu tion, and explained that the three factors of a
comparative analysis are conjunctive. Further, according to the United States, the Panel found that
the third and fourth alternative measures were not adequately identified to allow a meaningful
Article 2.2 comparison.
6.66. The Panel declines the complainants' request. The Panel notes that the complainants'
interim review requests and comments do not addr ess – let alone question – the Panel's analysis
of the four alternative measures and its conclusion that the complainants did not make a
prima facie case under Article 2.2 of the TBT Agreement for any of the four alternative measures.
In particular, the complainants did not question the Panel's findings that the complainants had not
persuasively demonstrated that the first two alternative measures achieve an equivalent degree of
contribution as the amended COOL measure, specifically how increased coverage would
compensate for less origin information provided on Labels A-C under these two alternatives.
Likewise, the complainants did not call into question the Panel's findings that the complainants had
not sufficiently explained how their third and fourth alternative measures would be implemented,
and thus had not adequately identified these alternatives to allow a meaningful Article 2.2
comparative analysis. Finally, the complainants did not contest the conjunctive nature of the
factors of an Article 2.2 comparative analysis, or the validity of the Appellate Body's reliance on
the conjunctive nature of these factors in the original dispute
25 referenced by the Panel in
paragraph 7.491.
6.67. Mexico requested the insertion of references into the footnotes to paragraph 7.515 to
exhibits submitted by Mexico in connection with the NAIS and Interstate Livestock Traceability
Rule. The United States commented that the Interstate Livestock Traceability Rule
(Exhibit MEX-82) is already referenced in multiple footnotes. As for other exhibits referred to by
Mexico (Exhibits MEX-83, MEX-84, and MEX-85), the United States commented that these are
APHIS documents submitted by Mexico, but that Mexico has not explained why these documents
(unlike the official regulation of the Interstate Livestock Traceability Final Rule) should be included.

25 In the original dispute, the Appellate Body held that "in most cases" a comparative analysis under
Article 2.2 "will involve a comparison of the trade-restrictiveness of, and the degree of achievement of the
objective by, the measure at issue, with that of possible alternative measures that may be reasonably available
and that are less trade restrictive than the challenged measure, taking account of the risks non-fulfilment
would create." Appellate Body Reports, US – COOL, para. 376 (original emphasis).
WT/DS384/RW • WT/DS386/RW

6.68. As section 7.6.5.4 already provides references to the Interstate Livestock Traceability Rule
as well as the parties' specific arguments on the third alternative measure, no further revisions to
the footnotes to paragraph 7.515 were considered necessary.
6.69. Regarding paragraph 7.518 , Canada commented that its reference to Uruguay's trace-
back system concerned the second stage, rather th an the second pillar of the first stage, of a
trace-back system. The United supported revision of this paragraph to reflect Canada's specific
arguments. The Panel revised paragraph 7.518 in light of the parties' comments.
6.70. The United States requested review of section 7.7 (paragraphs 7.617-7.643) in respect
of the Panel's reliance on the Appellate Body's reports in EC – Seal Products . The United States
noted that the circulation of those reports occurre d after the period for the parties to make their
arguments and submit evidence had ended. The Un ited States referred to the Appellate Body's
statement that "a Member's right to regulate under the sixth recital, is not, in principle, different
from the balance set out in the GATT 1994, where obligations such as national treatment in
Article III are qualified by the general exceptions provision of Article XX".
26 In addition, the
United States pointed to the Appellate Body's stat ement as to the lack of "any concrete examples
of a legitimate objective that could factor into an analysis under Article 2.1 of the TBT Agreement,
but would not fall within the scope of Article XX of the GATT 1994".
27 According to the United
States, the Panel's analysis "does not appear to take this further aspect of Article III:4, as found
by the Appellate Body, into account". The United States opined that the Panel's analysis "would
suggest that one would expect there to be a COOL measure that causes a detrimental impact on
imports yet is consistent with Article 2.1 of the TBT Agreement. According to the Appellate Body's
approach, then, there must be an Article XX ex ception that would be available for COOL."
Asserting that "the current circumstances are extraordinary", the United States contended that
"the parties were not able to shape their submissions" according to the Appellate Body's finding
regarding a responding Member's reliance on an Article XX exception with respect to a claim under
Article III:4 of the GATT 1994 even where the measure could be consistent with Article 2.1 of the
TBT Agreement. The United States therefore requ ested the Panel to "address the availability of
Article XX as an exception for Article III:4 with respect to COOL". In the view of the United States,
the Panel's "existing analysis would support finding under Article XX", particularly in respect of
reasonably available alternative measures. The United States considered that the Reports, "as
currently structured, would appear at odds with [the] principle" that "a Member's right to regulate
is not, in principle, different under Article 2.1 than under Article III:4".
6.71. Canada commented that "[t]he nature of the United States' request to the Panel is unclear".
Canada noted that the United States had not in voked Article XX as a defence, and was instead
asking the Panel to address "issues on the 'availability' of an unspecified Article XX defence".
Canada pointed to the burden of proof associated with Article XX of the GATT 1994 and asserted
that interim review is not an appropriate stage in panel proceedings for a party to make new
arguments or submit new evidence. Further, Canada disputed the suggestion that the findings of
the Appellate Body in EC – Seal Products were unforeseeable, arguing that these findings were in
line with those in US – Clove Cigarettes and simply upheld the panel's finding on the legal
standard for claims under Article III:4 of the GA TT 1994. Canada also disputed the United States'
suggestion that the Panel could "transpose findings under … the TBT Agreement to a hypothetical
analysis under GATT Article XX". In Canada's view, the United States could have structured its
defence in this case to anticipate the findings of the Appellate Body, and that in this case it simply
chose not to raise a defence under Article XX of the GATT 1994.
6.72. Mexico similarly opposed the United States' request, noting that interim review is "not the
stage for a complainant to seek a finding related to the general exceptions of the GATT 1994,
particularly considering that this defence was not raised by the United States" in these
proceedings. Mexico disagreed with the United States' view that the current circumstances are
"extraordinary", and contended that the Appellate Body's findings in EC – Seal Products were not
unforeseeable. According to Mexico, the United States' request is conditioned on the existence of a
measure that is consistent with Article 2.1 of the TBT Agreement and inconsistent with Article III:4
of the GATT 1994. Given the Panel's finding that th e amended COOL measure is inconsistent with

26 Citing Appellate Body Reports, EC – Seal Products, para. 5.122.
27 Citing Appellate Body Reports, EC – Seal Products, para. 5.128.
WT/DS384/RW • WT/DS386/RW

both Article 2.1 and Article III:4, Mexico argued that "the United States' request is based on a
hypothetical set of circumstances that does not exist in this dispute".
6.73. The Panel notes that section 7.7 applie s the legal standard under Article III:4 of the
GATT 1994 as recently clarified by the Appellate Body in EC – Seal Products . The Panel further
notes that the United States' request is quite general. The United States does not advance or
argue a defence under Article XX of the GATT 1994, nor does it identify any sub-paragraph of that
Article as relevant to the present dispute. The United States merely requests that the Panel
"address this aspect of the Article III:4/Article 2. 1 relationship and address the availability of
Article XX as an exception with respect to COOL".
6.74. The United States' position appears to be predicated on a perceived conflict between, on the
one hand, the Appellate Body's clarification of the relationship of national treatment under the
GATT 1994 and the TBT Agreement and, on the othe r hand, the implications for a hypothetical
measure found to be consistent with Article 2.1 of the TBT Agreement but in violation of
Article III:4 of the GATT 1994. The Panel has found the amended COOL measure to be in violation
of both Article 2.1 of the TBT Agreement and Ar ticle III:4 of the GATT 1994. Therefore, the Panel
is not faced with the situation hypothetically suggested by the United States. Under these
circumstances, it is unclear how the assessment requested by the United States would be
appropriate for securing a positive solution to the present dispute.
6.75. Moreover, accepting the United States' request at this stage would require examination of
an issue for which neither the United States, nor the complainants, have provided specific
evidence or argument. Indeed, at no point did the United States invoke Article XX of the
GATT 1994 or any relevant sub-paragraph(s) thereof, or adduce arguments under Article XX at an
appropriate stage of these proceedings. The Pane l therefore declines the United States' request
with respect to section 7.7.
6.76. Mexico requested the insertion of an additional citation into footnote 1362
(footnote 1380 in the Final Reports) to paragraph 7.648 to its written submission as to the
treatment of the terms "conflict" and "violation" as equivalent. The Panel supplemented
footnote 1362 (footnote 1380 in the Final Reports) to paragraph 7.648 as requested by Mexico.
7 FINDINGS
7.1 Claims
7.1. Canada and Mexico claim that the amended COOL measure is inconsistent with the following
four provisions of the covered Agreements:
a. Article 2.1 of the TBT Agreement and Article III:4 of the GATT 1994 because it accords
cattle and hogs imported from Canada and cattle imported from Mexico treatment less
favourable than that accorded to US cattle and hogs;
b. Article 2.2 of the TBT Agreement because it creates an unnecessary obstacle to
international trade, as it is more trade restrictive than necessary to fulfil a legitimate
objective, taking account of the risks non-fulfilment would create; and
c. Article XXIII:1(b) of the GATT 1994 because it nullifies or impairs benefits to Canada and
Mexico in respect of imports of cattle and, for Canada, also hogs to the US.

7.2 Order of analysis
7.2. The parties do not suggest a particul ar order of analysis. With one exception 29, their written
submissions address the national treatment claims first (Article 2.1 of the TBT Agreement, then

Article III:4 of the GATT 1994), followed by Articl e 2.2 of the TBT Agreement, and conclude with
the non-violation claim under Article XXIII:1(b) of the GATT 1994.
7.3. In general, "panels are free to structure the order of their analysis as they see fit" 30 – unless,
based on the "structure and logic" of the provisions at issue, "there exists a mandatory sequence
of analysis which, if not followed, would amount to an error of law" or affect the substance of the
analysis itself.31 We do not consider, nor do the parties contend, that there is any such mandatory
sequence of analysis in this compliance dispute.
7.4. The original panel noted that, given the principle of specificity, "if the [measure at issue] is a
technical regulation, then the analysis under the TBT Agreement would precede any examination
under the GATT 1994."32 Accordingly, the original panel – like other TBT panels 33 – addressed the
TBT claims before the GATT claims.
7.5. The original panel found that the original COOL measure was a "technical regulation" under
the TBT Agreement.34 The parties agree35 that the COOL measure, in its amended form, continues
to be a technical regulation. We agree with th e parties in this respect. As explained below 36,
the amended COOL measure meets the definition of a technical regulation in the TBT Agreement.37
7.6. Accordingly, we follow the approach of the original panel 38 and address the complainants'
TBT claims before addressing their claims under Articles III:4 and XXIII:1(b) of the GATT 1994.
Before turning to the complainants' legal claims , we provide an overview of the amended COOL
measure and address the scope of this compliance dispute.
7.3 The amended COOL measure
7.7. The measures examined in the original dispute included the "COOL statute" (the Agricultural
Marketing Act of 1946, as amended by the 2002 Fa rm Bill and the 2008 Farm Bill), and the
regulatory provisions implementing the COOL statute in the 2009 Final Rule (AMS)
(2009 Final Rule).
39 Other measures considered by the original panel have either expired or have
been withdrawn, and are not at issue in these compliance proceedings.40
7.8. Following the original panel and appellate proceedings, the Agricultural Marketing Service
(AMS) of the US Department of Agriculture (USDA) issued a final rule, effective 23 May 2013 41,

40 In addition to the COOL statute and 2009 Final Rule, the original panel identified two
Interim Final Rules (AMS and FSIS) and a letter from US Secretary of Agriculture Thomas J. Vilsack as falling
within the scope of its terms of reference. See Panel Reports, US – COOL, para. 7.21. The Interim Final Rules
(AMS and FSIS) were found to have expired at the time of the original panel's establishment and the original
panel made no findings or recommendations as to these Interim Rules. See Panel Reports, US – COOL,
paras. 7.22 and 7.33-7.34. As noted by the Appellate Body, referring to a USDA letter to industry
representatives, the United States pointed out that "the Vilsack letter was 'withdrawn' on 5 April 2012", and "at
the oral hearing Canada stated that it was no longer seeking specific rulings from the Appellate Body on this
measure." Appellate Body Reports, US – COOL, para. 251. The Vilsack letter has not been challenged or raised
in this compliance dispute.
41 The 2013 Final Rule specifies that "[t]he effective date of this regulation is May 23, 2013, and the rule
is mandatory as of that date. … However, AMS understands that it may not be feasible for all of the affected
entities to achieve 100% compliance immediately and that some entities will need time to achieve full
compliance with the amended provisions for 100% of muscle cut covered commodities. Therefore, during the
six month period following the effective date of the regulation, AMS will conduct an industry education and
WT/DS384/RW • WT/DS386/RW

"to make changes to the labelling provisions for muscle cut covered commodities and certain other
modifications to the program".42 This rule (2013 Final Rule) is the only regulatory change identified
by the parties as the United States' "measures taken to comply" with the DSB recommendations
and rulings in the original dispute.
43
7.9. In these Reports, the COOL statute and the 2009 Final Rule in its unamended form will be
jointly referred to as the "original COOL measur e". The COOL statute (which remains unchanged),
and the 2009 Final Rule as amended by the 2013 Final Rule, will be jointly referred to as the
"amended COOL measure".44
7.3.1 Amended COOL Labels
7.3.1.1 Definition of origin
7.10. The COOL statute defines the origin of mu scle cuts of meat as a function of the country
(or countries) where the animal from which th ey derive is born, raised, and slaughtered.
45 Under
the unamended provisions of the 2009 Final Rule, "rai sed" is defined as "the period of time from
birth until slaughter or in the case of animals imported for immediate slaughter … the period of
time from birth until date of entry into the United States". 46 The term "slaughtered" is defined as
"the point in which a livestock animal … is prepared into meat products (covered commodities) for
human consumption".
47 "Born" is not explicitly defined for cattle and hogs in either the original or
amended COOL measures.48
7.11. The 2009 Final Rule laid down origin labelling rules for meat based on the following five
categories established by the COOL statute:
a. Category A muscle cuts: United States country of origin;
b. Category B muscle cuts: multiple countries of origin;
c. Category C muscle cuts: imported for immediate slaughter;
d. Category D muscle cuts: foreign country of origin; and
e. Category E: ground meat.49
7.12. As the COOL statute is unchanged, these broad statutory categories remain applicable
under the amended COOL measure 50 – subject to the more detailed requirements of the
implementing rules discussed below.
7.13. Category A represents muscle cuts "[f]rom animals exclusively born, raised, and
slaughtered in the United States".51

means hatched from the egg". 2009 Final Rule, § 65.115.
49 See COOL statute, § 1638a(a)(2)(A)-(E); Panel Reports, US – COOL, para. 7.89.
50 According to the 2013 Final Rule, "[t]he [COOL] statute contemplates four different labeling
categories for meat, based on where the animal was born, raised, and/or slaughtered. This final rule preserves
these four different labeling categories for meat and is consistent with labeling criteria set forth in the statutory
scheme." 2013 Final Rule, p. 31370.
51 2009 Final Rule, § 65.180. See also COOL statute, § 1638a(a)(2)(A).
WT/DS384/RW • WT/DS386/RW

7.14. Categories B and C pertain to animals slaughtered in the United States but born and/or
raised in other countries, with distinct labelling requirements for each under the original and
amended COOL measures.
52 While both Categories B and C denote mixed-origin livestock 53,
Category C is specifically reserved for animals "imported into the United States for immediate
slaughter".54 Unamended provisions of the 2009 Final Rule define the term "imported for
immediate slaughter" as "consignment directly from the port of entry to a recognized slaughtering
establishment and slaughtered within 2 weeks from the date of entry". 55 Thus, an animal imported
into the United States more than two weeks prior to its US slaughter would not qualify as being
"imported for immediate slaughter", and would fall into Category B.
7.15. Under the original COOL measure, Category D extended to "[i]mported covered
commodities for which origin has already been established as defined by this law (e.g., born,
raised, and slaughtered or produced) and for which no production steps have occurred in the
United States".56 The 2013 Final Rule amends this provision and now refers to "[m]uscle cut
covered commodities derived from an animal that was slaughtered in another country … including
muscle cut covered commodities derived from an animal that was born and/or raised in the
United States and slaughtered in another country". 57 However, under the 2013 Final Rule,
Category D origin is still designated according to the definition used for customs purposes 58,
i.e. based on substantial transformation. For muscle cuts of meat, origin according to this
definition is the country where the animal is slaughtered.59
7.16. With respect to Category E products (ground meat), unamended provisions of the
2009 Final Rule refer to "all countries of origin contained therein or that may be reasonably
contained therein", adding that "when a raw material from a specific origin is not in a processor's
inventory for more than 60 days, that country shall no longer be included as a possible country of
origin".
60
7.3.1.2 Information on labels
7.17. The original COOL measure established labels for each of the above five categories, with
various rules and flexibilities for the corresponding Labels A, B, C, D, and E. The 2009 Final Rule
provided that muscle cuts in Category A "may bear a declaration that identifies the United States
as the sole country of origin at retail". 61 In such situation, Label A could state "Product of the
United States" or some other variation permitted under the original COOL measure.62 With respect
to Label B, the 2009 Final Rule provided that "[f]or muscle cut covered commodities derived from

52 See Table 1 below.
53 As the Appellate Body held, "[b]oth Categories B and C involve meat of mixed origin, in the sense
that they have more than one country of origin. For each of these categories, at least one production step has
taken place outside the United States, and at least one production step has taken place within the
United States." See Appellate Body Reports, US – COOL, para. 244.
54 In the COOL statute, Category B is under the heading "multiple countries of origin" and applies to
"meat that is derived from an animal that is – (I) not exclusively born, raised, and slaughtered in the
United States; (II) born, raised, or slaughtered in the United States, and (III) not imported into the
United States for immediate slaughter". Category C is confined exclusively to animals "imported for immediate
slaughter". COOL statute, §§ 1638a(a)(2)(B) and (C). But see also para. 7.17 regarding the more specific
origin requirements for Category B animals under the 2009 Final Rule.

59 See Panel Reports, US – COOL, para. 7.674; and Appellate Body Reports, US – COOL, para. 241.
The complainants explain that the United States applies a "substantial transformation" test and, for NAFTA
countries, a test based on change in tariff classification to determine origin. According to the complainants, the
result under both tests is to designate the place of slaughter as the country of origin. See Canada's first written
submission, para. 18 and footnote 53; and Mexico's first written submission, para. 32 and footnote 30.
60 2009 Final Rule, § 65.300(h). The USDA explained that "if a country of origin is utilized as a raw
material source in the production of ground beef, it must be listed on the label", subject to the 60-day
"inventory allowance" for "when countries may no longer be listed". 2009 Final Rule, p. 2671.
61 2009 Final Rule, § 65.300(d). See also COOL statute, § 1638a(a)(2)(A).
62 2009 Final Rule, p. 31369. See also Panel Reports, US – COOL, para. 7.100 and §§ 65.400(a) ("[t]he
declaration of the country of origin or a product may be in the form of a statement such as 'Product of USA,
'Produce of the USA'") and 65.400(e) (describing acceptable country abbreviations, including "U.S. or USA" for
the "United States of America").
WT/DS384/RW • WT/DS386/RW

animals that were born in Country X or (as applicable) Country Y, raised and slaughtered in the
United States … the origin may be designated as Product of the United States, Country X, and (as
applicable) Country Y".
63 In the case of Label C, when "an animal was imported into the
United States for immediate slaughter as defined in § 65.180, the origin of the resulting meat
products derived from that animal [had to] be designated as Product of Country X and the
United States".64 As referenced above, Label D reflected the country of origin of imported muscle
cuts "as declared to U.S. Customs and Border Pr otection", namely the country of slaughter based
on the principle of substantial transformation. 65 Finally, Label E required that ground meat
products "shall list all countries of origin contained therein or that may be reasonably contained
therein" based on the 60-day "inventory allowance" under the 2009 Final Rule.
66
7.18. As a result of the 2013 Final Rule, the amended COOL measure imposes new labelling
requirements for Labels A, B, and C. 67 For muscle cuts from animals slaughtered in the
United States, the amended COOL measure now generally requires Labels A, B, and C to indicate
the place of occurrence of each production step (born, raised, and slaughtered).
68
7.19. With respect to Label D, which applies to muscle cuts from non-US slaughtered animals,
the 2013 Final Rule preserves the required origin label declaration of the original COOL measure,
but adds a voluntary option to provide more information. Thus, Label D must continue to indicate
the origin "as declared to U.S. Customs and Border Protection at the time the products entered the
United States, through retail sale (e.g., 'Product of Country X')".
69 In addition, Label D
"may include more specific location information related to production steps (i.e., born, raised, and
slaughtered) provided records to substantiate the claims are maintained".
70
7.20. The requirements of Label E for ground meat were not changed by the 2013 Final Rule. 71
Label E for ground meat products "shall [continue to] list all countries of origin contained therein
or that may be reasonably contained therein" based on the 60-day "inventory allowance" under
the 2009 Final Rule.
72
7.21. Table 1 below compares the origin definitions and examples of basic muscle cut labels under
the 2009 and 2013 Final Rules.

63 2009 Final Rule, § 65.300(e)(1). The COOL statute provides for Category B that retailers "may
designate the country of origin of such covered commodity as all of the countries in which the animal may have
been born, raised, or slaughtered". COOL statute, § 1638a(a)(2)(B).
64 2009 Final Rule, § 65.300(e)(3). The 2009 Final Rule also stipulates that the countries on Label B
"may be listed in any order", as distinct from Label C which did not have a similar flexibility.

68 See 2013 Final Rule, §§ 65.300(d) and (e), p. 31367. The United States and Mexico have stated that
this is effectively a "single label" for these categories of meat. See United States' first written submission,
para. 24; and Mexico's first written submission, para. 119. Canada contends that "[w]hether the labels are
considered in the singular or the plural, it is the content of the labels and the incentives they create that are
relevant." Canada's second written submission, para. 55.
69 As the 2013 Final Rule points out, "[u]nder this final rule, these labeling requirements for imported
muscle cut covered commodities remain unchanged." 2013 Final Rule, § 65.300(f)(2) and p. 31369.
70 2013 Final Rule, § 65.300(f)(2). Note that the provisions for voluntarily providing such information

7.3.1.3 Methods of providing origin information
7.22. The amended COOL measure permits the same methods for conveying origin information as
the original COOL measure. In particular, the COOL statute sets forth that country of origin
information "may be provided to consumers by means of a label, stamp, mark, placard, or other
clear and visible sign on the covered commodity or on the package, display, holding unit, or bin
containing the commodity at the final point of sale to consumers". 73 The 2009 Final Rule
additionally provides that "[c]ountry of origin declarations can either be in the form of a placard,
sign, label, sticker, band, twist tie, pin tag, or other format that allows consumers to identify the
country of origin".
74 The declaration of country of origin in any of these forms "may be typed,
printed, or handwritten" 75 and "must be legible and placed in a conspicuous location, so as to
render it likely to be read and understood by a customer under normal conditions of purchase".76
7.23. The USDA explained in the 2009 Final Rule that "[i]n order to provide the industry with as
much flexibility as possible, this rule does no t contain specific requirements as to the exact
placement or size of the country of origin … declaration", provided that the declaration be "legible
and conspicuous, and allow consumers to find the country(ies) of origin … easily and read them
without strain when making their purchases". 77 The 2013 Final Rule adds with respect to labels
and stickers that "abbreviations for the production steps are permitted as long as the information
can be clearly understood by consumers", including the following specific examples: "'brn' as
meaning 'born'"; "'raisd' as meaning 'raised'"; "'slghtrd' as meaning 'slaughtered'"; and "'hrvstd'
as meaning 'harvested'"
78.79
7.24. Like the original COOL measure, the amended COOL measure provides that "[i]n general,
country abbreviations are not acceptable" on meat labels. 80 However, declarations of origin may
use "country abbreviations, as permitted by Cust oms and Border Protection, such as 'U.S.' and
'USA' for the 'United States of America'".81
7.3.2 Coverage of the amended COOL measure
7.3.2.1 Products at issue
7.25. The amended COOL measure continues to a pply to a wide range of "covered commodities",
which include muscle cuts of beef and pork as well as ground beef and pork.
82
7.26. As in the original dispute, the only covered products challenged in this compliance dispute
are imported Canadian cattle and hogs and imported Mexican cattle, which are used in the

73 COOL statute, § 1638a(c)(1). See also Panel Reports, US – COOL, para. 7.110.
74 2009 Final Rule, § 65.400(a). See also Panel Reports, US – COOL, para. 7.110.
75 2009 Final Rule, § 65.400(c).
76 2009 Final Rule, § 65.400(b). See also Panel Reports, US – COOL, para. 7.111.
77 2009 Final Rule, p. 2663.
78 The 2009 Final Rule provided that "[f]or purposes of labeling under this part, the word harvested may
be used in lieu of slaughtered". 2009 Final Rule, § 65.250. The 2013 Final Rule states that "[t]he current COOL
regulations permit the term 'harvested' to be used in lieu of 'slaughtered.' This final rule retains that flexibility."
2013 Final Rule, pp. 31369-31368.
79 2013 Final Rule, p. 31369. In explaining the allowance for such abbreviations, the USDA stated that it
"recognizes that there is limited space to include the specific location information for each production step".
80 2009 Final Rule, § 65.400(e).
81 2013 Final Rule, p. 31369. See also Panel Reports, US – COOL, para. 7.112.
82 According to the COOL statute, "[i]n general [t]he term 'covered commodity' means (i) muscle cuts of
beef, lamb, and pork; (ii) ground beef, ground lamb, and ground pork; (iii) farm-raised fish; (iv) wild fish;
(v) a perishable agricultural commodity; (vi) peanuts; and (vii) meat produced from goats; (viii) chicken, in
whole and in part; (ix) ginseng; (x) pecans; and (xi) macadamia nuts." COOL statute, § 1638(2)(A) (emphasis
added). According to the 2009 Final Rule, "[c]overed commodity means: (1) Muscle cuts of beef, lamb,
chicken, goat, and pork; (2) Ground beef, ground lamb, ground chicken, ground goat, and ground pork;
(3) Perishable agricultural commodities; (4) Peanuts; (5) Macadamia nuts; (6) Pecans; and (7) Ginseng."
2009 Final Rule, § 65.135(a) (emphasis added). The 2013 Final Rule does not amend this provision of the
2009 Final Rule.
WT/DS384/RW • WT/DS386/RW

United States to produce beef and pork commodities covered by the COOL measure. 83 As the
2013 Final Rule does not modify the original COOL measure in respect of its application to meat
and livestock, the following findings from the original dispute are equally valid for the amended
COOL measure:
[T]he COOL measure applies not only to beef and pork but also to cattle and hogs.
Formally speaking, the category of "cover ed commodities" under the COOL measure
includes only beef and pork, not livestock, and the labelling requirements under the
COOL measure apply to beef and pork only "at the final point of sale of the covered
commodity to consumers". … [H]owever, without upstream livestock producers and
processors providing the necessary information on origin as defined by the
COOL measure, these retail labelling requirements are impossible to fulfil.
The COOL measure recognizes this by creating obligations not only for retailers of beef
and pork but also for the broad Category of "any person engaged in the business of
supplying [these] to a retailer". The latter Category of upstream market participants
"shall provide information to the retailer indicating the country of origin of the covered
commodity". The COOL measure supports this obligation with an enforcement
mechanism, including fines – again, applicable to both retailers and their suppliers.
84
7.3.2.2 Exemptions
7.27. The amended COOL measure retains the or iginal COOL measure's three main exemptions
from coverage, while slightly adjusting the first one:
a. entities not meeting the definition of the term "retailer";
b. ingredients in "processed food items"; and
c. products served in a "food service establishment".85
7.28. Both the original and amended COOL measures require labelling at the retail stage. 86
The original COOL measure defined "retailers" as "any person licensed as a retailer under the
Perishable Agricultural Commodities Act of 1930" (PACA)." 87 Pursuant to the terms of PACA, this
means an entity whose invoice costs of purchases of perishable agricultural commodities are in
excess of US $230,000 in any calendar year. 88 Whereas the original COOL measure defined the
term "retailer" as "retailer licensed under [PACA]", the 2013 Final Rule amends the definition to
"any person subject to be licensed as a retailer under [PACA]".
89
7.29. The COOL statute excludes from its scope any covered commodity that is "an ingredient in a
processed food item".90 The 2009 Final Rule defines "processed food item" as "a retail item derived
from a covered commodity that has undergone specific processing resulting in a change in the

character of the covered commodity, or that has been combined with at least one other covered
commodity or other substantive food component". 91 The 2013 Final Rule does not modify these
provisions.92
7.30. The COOL statute also exempts "food service establishments" from its labelling
requirements.93 The COOL statute defines the term "food service establishment" as "a restaurant,
cafeteria, lunch room, food stand, saloon, tavern, ba r, lounge, or other similar facility operated as
an enterprise engaged in the business of selling food to the public". 94 As noted in the original
proceedings, the 2009 Final Rule further develops th is definition by adding that "[s]imilar food
service facilities include salad bars, delicatessens, and other food enterprises located within retail
establishments that provide ready-to-eat foods th at are consumed either on or outside of the
retailer's premises".
95 The exemption of food service esta blishments is not amended by the
2013 Final Rule.96
7.3.3 Flexibilities
7.31. The original COOL measure allowed for three main flexibilities from its general labelling
requirements: (i) the commingling flexibility; (ii) the country order flexibility; and (iii) the multiple
countries of raising flexibility. The 2013 Final Rule has removed the first two flexibilities,
and amended the third one.
7.3.3.1 Commingling flexibility removed
7.32. The 2009 Final Rule included flexibility with respect to the commingling of muscle cuts from
US-slaughtered livestock. This flexibility applied specifically between Label A and Label B
97 muscle
cuts, as well as between Label B and Label C 98 muscle cuts, "commingled during a production
day".99

91 2009 Final Rule, § 65.220. The definition of "processed food item" further states that "[s]pecific
processing that results in a change in the character of the covered commodity includes cooking (e.g., frying,
broiling, grilling, boiling, steaming, baking, roasting), curing (e.g., salt curing, sugar curing, drying), smoking
(hot or cold), and restructuring (e.g. emulsifying and extruding)." See also Panel Reports, US – COOL,

92 See 2009 Final Rule, § 65.300(c); 2013 Final Rule, p. 31372 (responding to comments that "the
definition of processed should be narrowed such that more products are covered" as being "outside the scope
of this rulemaking"); Canada's first written submission, para. 18; and Mexico's first written submission,

"outside the scope of this rulemaking"); Canada's first written submission, para. 18; and Mexico's first written
submission, para. 46.
97 According to the original COOL measure, "[f]or muscle cut covered commodities derived from animals
born, raised, and slaughtered in the U.S. [i.e. Label A muscle cuts] that are commingled during a production
day with muscle cut covered commodities described in § 65.300(e)(1) [i.e. Label B muscle cuts], the origin
may be designated as Product of the United States, Country X, and (as applicable) Country Y." 2009 Final Rule,
§ 65.300(e)(2).
98 According to the original COOL measure, "[f]or muscle cut covered commodities derived from animals
that are born in Country X or Country Y, raised and slaughtered in the United States [i.e. Label B muscle cuts],
that are commingled during a production day with muscle cut covered commodities that are derived from
animals that are imported into the United States for immediate slaughter as defined in § 65.180 [i.e. Label C
muscle cuts], the origin may be designated as Product of the United States, Country X, and (as applicable)
Country Y." 2009 Final Rule, § 65.300(e)(2).
99 "As discussed in the 2009 final rule, USDA considers that commingling typically takes place in two
different scenarios. First, muscle cut covered commodities derived from animals born, raised, and slaughtered
in the United States that are commingled during a production day with muscle cut covered commodities
derived from animals that were raised and slaughtered in the United States, and were not derived from
animals imported for immediate slaughter, could be designated as, for example, Product of the United States,
Country X, and (as applicable) Country Y. Second, muscle cut covered commodities derived from animals that
are born in Country X or Country Y, raised and slaughtered in the United States, that are commingled during a
production day with muscle cut covered commodities that are derived from animals that are imported into the
WT/DS384/RW • WT/DS386/RW

7.33. The original panel noted that "commingling c[ould] take place in multiple stages of the meat
production process (e.g. processors and packers), including at the retail level."100 As to what might
be commingled, the 2009 Final Rule referred to "commingled covered commodities" 101, defining
"covered commodities" in relevant part as "[m]us cle cuts of beef and pork" and "[g]round beef …
and ground pork".102 In addition, as the original panel noted, the original COOL measure foresaw
the possibility of commingling relevant types of animals.103 Both the original104 and amended COOL
measures105 describe commingling as potentially involving animals, not just muscle cuts.
7.34. The 2013 Final Rule deleted the original COOL measure's provisions on the modalities of
commingling.106 Thus, as the USDA points out, the amended COOL measure "eliminates the
allowance for commingling of muscle cut covered commodities of different origins." 107 No party
contests that the commingling flexibility is now completely eliminated. At the same time, the
parties continue to differ on the extent to which this eliminated commingling flexibility was actually
used, and disagree as to the implications of commingling for this compliance dispute.108
7.3.3.2 Country order flexibility removed
7.35. The 2009 Final Rule contained flexibility concerning the order of countries of origin on
Label B.109 The countries of origin could be listed in "any order" 110, so Label B for muscle cuts of,
for example, mixed US-Canadian origin could read "Product of U.S., Canada or Product of Canada,
U.S."111 As a result, the Appellate Body noted that "[b]ecause the countries of origin for
Category B meat c[ould] be listed in any order [under the original COOL measure], the labels for
Categories B and C meat could look the same in practice."
112
7.36. Under the 2009 Final Rule, this country order flexibility also applied cumulatively in regard
to the commingling flexibility between Label A and Label B 113, as well as between Label B and
Label C114 muscle cuts.115 Thus, the flexibility on the order of countries of origin, applied together

103 See Panel Reports, US – COOL, para. 7.705.
104 As noted in the 2009 Final Rule, "[t]he Agency recognizes that the multitude of different production
practices and possible sales transactions can influence the value determinations made throughout the supply
chain resulting in instances of commingling of animals or covered commodities, which will have an impact
when mixing occurs." 2009 Final Rule, p. 2670.

p. 31384 ("facilities that currently commingle domestic and foreign-origin cattle or hogs").

measure's definition of "commingled covered commodities." See footnote 101 above.

112 Appellate Body Reports, US – COOL, para. 245 (footnote omitted). Likewise, the original panel found
that "specific Labels B and C may look the same, provided that the countries involved in the production of the
Label B and C muscle cuts in question are the same." Panel Reports, US – COOL, para. 7.288
(footnotes omitted).
113 According to the original COOL measure, "[f]or muscle cut covered commodities derived from
animals born, raised, and slaughtered in the U.S. [i.e. Label A muscle cuts] that are commingled during a
production day with muscle cut covered commodities described in § 65.300(e)(1) [i.e. Label B muscle cuts],
the origin may be designated as Product of the United States, Country X, and (as applicable) Country Y."
2009 Final Rule, § 65.300(e)(2).
114 According to the original COOL measure "[f]or muscle cut covered commodities derived from animals
that are born in Country X or Country Y, raised and slaughtered in the United States [i.e. Label B muscle cuts],
that are commingled during a production day with muscle cut covered commodities that are derived from
animals that are imported into the United States for immediate slaughter as defined in § 65.180 [i.e. Label C
WT/DS384/RW • WT/DS386/RW

with the commingling flexibilities, could result in commingled Label A, B, and C meat carrying the
same, identical label:
When Category A and Category B meat is commingled during a single production day,
all of the resulting meat may be labelled as if it were Category B meat, even though a
particular piece of meat may have been derived from a Category A animal. Further,
when Category B and Category C meat is commingled during a single production day,
all of the resulting meat may be labelled as if it were Category B meat, even though a
particular piece of meat may have been derived from a Category C animal. In both
cases, since the resulting meat may be labelled as if it were Category B meat, the
declared countries of origin for all commingled meat may be listed in any order.
116
7.37. By replacing the relevant provision in the 2009 Final Rule 117, the 2013 Final Rule eliminated
the country order flexibility altogether, including as applied in combination with the now removed
commingling flexibility.
7.3.3.3 Amended multiple countries of raising flexibility
7.38. In general, the 2013 Final Rule requires Labels B and C to "specifically identify the
production steps occurring in each country." 118 At the same time, based on practical
considerations119, it includes some flexibility:
If an animal is raised in the United States as well as another country (or multiple
countries), the raising occurring in the other country (or countries) may be omitted
from the origin designation.
120
7.39. This flexibility does not apply to Label C ("if the animal was imported for immediate
slaughter"), or "where by doing so the muscle cut covered commodity would be designated as
having a United States country of origin." 121 The parties dispute the implications of this flexibility
and its carve-outs for the complainants' TBT claims.122

muscle cuts], the origin may be designated as Product of the United States, Country X, and (as applicable)
Country Y." 2009 Final Rule, § 65.300(e)(2). See also ibid. p. 2659, 2661, and 2662.
115 According to the original COOL measure, "[i]n each case of paragraphs (e)(1), (e)(2), and (e)(4) of
this section, the countries may be listed in any order." 2009 Final Rule, § 65.300(e) (4). As the original panel
noted, "[t]he 2009 Final Rule (AMS) further provides that the labelled countries may be listed in any order
when the meat is derived from animals classified as Category B, or when meat falling under categories A and
B, as well as B and C, is commingled during a single production day." Panel Reports, US – COOL, para. 7.97
(footnote omitted).
116 Appellate Body Reports, US – COOL, para. 246 (footnotes omitted). See also ibid. paras. 336-337.
As the original panel held, "if Category A and B animals are commingled at the slaughterhouse, the meat
derived thereof should, in principle, use Label B. If this Label B meat is commingled at the retail level with
Label C meat, the resulting group can use Label B or C. Assuming that the retailer decides to use Label C for
that group of meat, the consumer has no certainty as to the origin of meat as defined by the United States. In
this scenario, the consumer could alternatively believe that this meat comes from any of the following: (i)
animals born and raised in country X and slaughtered in the United States; (ii) animals born in country X and
raised and slaughtered in the United States that were commingled with animals born and raised in country X
and slaughtered in the United States; or (iii) animals born in country X and raised and slaughtered in the
United States that simply list the country names in any order." Panel Reports, US – COOL, para. 7.705.
117 2013 Final Rule, § 65.300(e).
118 2013 Final Rule, § 65.300(e).
119 According to the 2013 Final Rule, "if animals are born and raised in another country and
subsequently further raised in the United States, only the raising that occurs in the United States needs to be
declared on the label, as it is understood that an animal born in another country will have been raised at least
a portion of its life in that other country. Because the country of birth is already required to be listed in the
origin designation, and to reduce the number of required characters on the label, the Agency is not requiring
the country of birth to be listed again as a country in which the animal was also raised. Accordingly, under this
final rule, the production step related to any raising occurring outside the United States may be omitted from
the origin designation of these commodities." 2013 Final Rule, p. 31368.

122 See paras. 7.233-7.244 below.
WT/DS384/RW • WT/DS386/RW

7.40. The multiple countries of raising flexibility under the 2013 Final Rule resembles the flexibility
under the 2009 Final Rule, which also applied only to Category B muscle cuts:
[I]f animals are raised in another country and the United States, provided the animals
are not imported for immediate slaughter as defined in § 65.180, the raising that
occurs in the United States takes precedence over the minimal raising that occurred in
the animal's country of birth.123
7.41. According to the USDA, "it is understood that an animal born in another country will have
been raised at least a portion of its life in that other country."124
7.42. The main difference between the two versions of this flexibility is that the 2013 Final Rule
specifies that the other country or countries of raising may be "omitted" 125, whereas the
2009 Final Rule refers to the US raising "tak[ing] precedence" 126 over the raising in the country of
birth. Under the 2009 Final Rule, Label B did not need to show point-of-production information
explicitly, although origin was based on such information. A muscle cut from a US-slaughtered
animal born in Canada, and raised in Canada and the United States, could have carried a "Product
of United States, Canada" label. US raising "taking precedence" over Canadian raising had no
practical implication for this label. The label had to mention Canada in any event, given the place
of birth.
127 Conversely, under the 2013 Final Rule, the flexibility means that for animals raised in
the country of birth and the United States, Label B may read "'Born in Country X, Raised and
Slaughtered in the United States' in lieu of 'Bor n and Raised in Country X, Raised and Slaughtered
in the United States'".128
7.43. The multiple countries of raising flexibility under the 2013 Final Rule also allows for omitting
"countries" of raising. 129 Thus, for instance, a Label B may now read "'Born in Country X, Raised
and Slaughtered in the United States' in lieu of 'Born and Raised in Country X, Raised in Country Y,
Raised and Slaughtered in the United States'". 130 By contrast, the corresponding flexibility in the
2009 Final Rule covered only the "minimal raising that occurred in the animal's country of birth."131
In practice, this was again inconsequential for the label. Muscle cuts from an animal (i) born in
Canada; (ii) raised in Canada, Mexico, and the United States; and (iii) slaughtered in the
United States would carry a North American La bel B ("Product of the United States, Canada,
Mexico") in any case. Although raising in the United States could take precedence over raising in
Canada, the label had to mention Canada in any event, given the place of birth.
132
7.3.4 Label variations in light of the flexibilities
7.44. Table 2 below compares some possible variations of the muscle cut labels under the original
and the amended COOL measures, in light of the or iginal flexibilities as removed or amended by

7.3.5 Unchanged recordkeeping and verification rules
7.45. The amended COOL measure leaves the original COOL measure's recordkeeping and
verification rules unchanged. 133 In particular, the recordkeeping and verification provisions of the
COOL statute134 and its prohibition of traceback 135 remain in effect. Further, the 2013 Final Rule
does not amend the 2009 Final Rule's recordkeeping provisions. 136 Although the parties agree that
the amended COOL measure leaves the pre-existi ng rules on recordkeeping and verification
unchanged137, they dispute whether the amended COOL measure entails more onerous
recordkeeping and verification in practice.138
7.4 Scope of the compliance dispute
7.46. According to the United States, the complainants should not be allowed an "unfair second
chance" to challenge unchanged aspects of the original COOL measure, or to use compliance
proceedings to "re-raise" claims and argume nts rejected in the original proceedings.
139
The United States identifies two aspects of the original COOL measure that "were not the subject
of DSB recommendations and rulings and remained unchanged": (i) the ground meat rule; and
(ii) the prohibition of a trace-back system. According to the United States, these are outside the
terms of reference of this compliance Panel.
140
7.47. The task of a compliance panel is to "consider th[e] new measure in its totality", which
requires "consider[ing] both the measure itself and the measure's application". 141 In doing so, a
compliance panel is "not confined to examining the 'measures taken to comply' from the
perspective of the claims, arguments and factual circumstances that related to the measure that
was the subject of the original proceedings".
142 At the same time, compliance proceedings should
not allow a complainant to re-litigate a claim regarding unchanged aspects of an original
measure.
143 Nor may a complainant use compliance claims to "re-open" issues decided in
substance in the original proceedings.144
7.48. We note that the complainants' panel requests focus on muscle cut labels; they do not refer
to either the ground meat rules or the trace-back prohibition. 145 Accordingly, the ground meat

133 For a description of these rules, see Panel Reports, US – COOL, paras. 7.116-7.121.
134 According to the COOL statute:
"(1) The Secretary may conduct an audit of any person that prepares, stores, handles, or distributes a
covered commodity for retail sale to verify compliance with this subchapter (including the regulations
promulgated under section 1638c(b) of this title).
(2)(A) A person subject to an audit under paragraph (1) shall provide the Secretary with verification of
the country of origin of covered commodities. Records maintained in the course of the normal conduct
of the business of such person, including animal health papers, import or customs documents, or
producer affidavits, may serve as such verification." COOL statute, § 1638a(d)(1) and (2)(A).
135 According to the COOL statute, "[t]he Secretary shall not use a mandatory identification system to
verify the country of origin of a covered commodity." COOL statute, § 1638a(f)(1).

rules and the trace-back prohibition are outside our terms of reference 146, and we could not
address them as claims in these proceedings even if the complainants had characterised them as
such subsequent to their requests for establishing this compliance Panel.
7.49. The complainants confirm that they are not bringing claims against the unchanged ground
meat labelling scheme and the trace-back prohib ition, but rather are referencing these as
arguments.147 Indeed, there is an important distinction to be made between claims, i.e. allegations
of violation of the substantive provisio ns of the WTO covered agreements, and arguments,
i.e. means whereby a party progressively develops and supports its claims. 148 Our mandate is
limited to reviewing the complainants' above-mentioned claims 149 with regard to aspects of the
amended COOL measure identified in the complain ants' panel requests. In reviewing these claims,
however, we are not precluded from considering the complainants' arguments concerning the
ground meat rule and the trace-back prohibition.150
7.5 Article 2.1 of the TBT Agreement
7.5.1 Legal test
7.50. The complainants bring national treatmen t claims under both the TBT Agreement and the
GATT 1994.
151 In relevant part, Article 2.1 of the TBT Agreement provides:
Members shall ensure that in respect of tec hnical regulations, products imported from
the territory of any Member shall be accorded treatment no less favourable than that
accorded to like products of national origin … .
7.51. The parties agree152 on the three main criteria to establish a violation of national treatment
under Article 2.1:
a. the measure at issue is a "technical regulation" as defined in Annex 1.1 to the
TBT Agreement;
b. the imported and domestic products at issue are "like products"; and
c. the measure at issue accords less favourable treatment to imported products than to like
domestic products.153
7.5.2 Technical regulation
7.52. According to the TBT Agreement, a "technical regulation" is a "[d]ocument which lays down
product characteristics or their related processes and production methods, including the applicable

146 Appellate Body Reports, Korea – Dairy, para. 139; and EC – Hormones, para. 156. See also
Constitution of the Panel, Note by the Secretariat, WT/DS384/27 and WT/DS386/26.
147 Mexico's second written submission, paras. 19, 20, and 71; and Canada's second written submission,
paras. 40 and 43-44 (emphasis added).
148 As the Appellate Body held, claims "must be clearly set out in the request for the establishment of
the panel", while arguments "do not need to be set out in detail in a panel request; rather, they may be
developed in the submissions made to the panel." Appellate Body Report, Dominican Republic – Import and
Sale of Cigarettes, para. 121. See also Mexico's second written submission, para. 16.
149 See section 7.1 above. According to the Appellate Body, "[t]h[e] task [of a compliance panel] is
circumscribed by the specific claims made by the complainant when the matter is referred by the DSB for an
Article 21.5 proceeding. It is not part of the task of a panel under Article 21.5 to address a claim that has not
been made." Appellate Body Report, US – Shrimp (Article 21.5 – Malaysia), para. 87.
150 According to the Appellate Body, "[p]anels are inhibited from addressing legal claims falling outside
their terms of reference. However, nothing in the DSU limits the faculty of a panel freely to use arguments
submitted by any of the parties … to support its own findings and conclusions on the matter under its
consideration." Appellate Body Report, EC – Hormones, para. 156.
151 See section 7.1 above.

administrative provisions, with which compliance is mandatory. It may also include or deal
exclusively with terminology, symbols, packaging, marking or labelling requirements as they apply
to a product, process or production method."154
7.53. In light of this definition, the original COOL measure was found to be a "technical
regulation" based on three well-established criteria155:
a. compliance with the original COOL measure was mandatory;
b. the original COOL measure applied to an id entifiable product or group of products
(namely certain types of meat and livestock); and
c. the original COOL measure laid down one or more product characteristics by imposing a
country of origin labelling requirement.156
7.54. The complainants argue that there are no changes under the amended COOL measure to
alter this finding. 157 The United States accepts that it is "not in dispute" that the amended COOL
measure is a technical regulation.158
7.55. As noted 159, the statutory element of the COOL measure, the COOL statute, remains
unchanged. Accordingly, the original panel's findings that relevant aspects of the COOL statute
fulfil the above three requirements 160 also remain valid for the amended COOL measure.
As regards the regulatory element of the amen ded COOL measure, the 2013 Final Rule amends
the 2009 Final Rule only partially. As explained 161, the main changes introduced by the
2013 Final Rule concern the introduction of point-of-production labelling for Category A-C muscle
cuts as well as the elimination of the commingling and country order flexibilities. These changes do
not affect aspects of the 2009 Final Rule examined by the original panel of relevance to the criteria
and definition of a technical regulation.
162
7.56. Therefore, we find that the amended COOL measure continues to be a "technical regulation"
as defined by the TBT Agreement.

159 See paras. 7.7-7.9 above.
160 In relation to the three applicable criteria, the original panel found that the COOL statute: firstly,
"sets out the core [COOL] requirement by using the word 'shall'" (citing COOL statute, § 1638a(a)(1)) and
"refers to the [COOL] requirement as 'the mandatory country of origin requirement'" (citing COOL statute,
§ 1638a(a)(2)(B)(ii)); secondly, it "explicitly defines 'covered commodity' for country of origin labelling
purposes as including '(i) muscle cuts of beef ... and pork' and '(ii) ground beef ... and ground pork'" (citing
COOL statute, § 1638(2)); and thirdly, "there is no dispute among the parties that the COOL measure lays
down a country of origin labelling requirement", and that "the obligations set out by the [original]
COOL measure, including the information requirement for '[a]ny person engaged in the business of supplying a
covered commodity to a retailer', are closely related to this essential function" (citing COOL statute,
§ 1638a(e)). See Panel Reports, US – COOL, paras. 7.157, 7.161, 7.202, and 7.212. These findings of the
original panel were not appealed.
161 See section 7.3 above.
162 For instance, the original panel found that the 2009 Final Rule "contains the word 'mandatory' in its
very title, and consistently refers to the essence of the COOL measure as 'mandatory COOL'" and sets out
obligations and information requirements for the original COOL measure for "any person engaged in the
business of supplying a covered commodity to a retailer" (citing 2009 Final Rule, § 65.500(b)(3)). See Panel
Reports, US – COOL, paras. 7.118 and 7.161. These findings of the original panel were not appealed.
WT/DS384/RW • WT/DS386/RW

7.5.3 Likeness
7.57. The original panel found that "Canadian cattle and US cattle, and Mexican cattle and US
cattle, are 'like products', and that Canadian hogs and US hogs are also 'like products' for purposes
of Article 2.1".
163
7.58. The complainants argue that there is no relevant change to the factual circumstances
supporting this finding, and that the imported and domestic products at issue in this case continue
to be "like".
164 The United States affirms that likeness is "not in dispute" in these compliance
proceedings.165
7.59. Absent any factual change relevant for assessing likeness, we find that the relevant
products continue to qualify as like products. T hus, as the original panel held, "Canadian and US
cattle are like products; moreover, Canadian and US hogs are also like products. Further, Mexican
cattle … and US cattle … are also like products." 166
7.5.4 Less favourable treatment
7.60. In the context of Article 2.1, the part ies' disagreement centres on whether the amended
COOL measure accords less favourable treatment to Canadian and Mexican products than that
accorded to like products of the United States.
7.61. The parties agree
167 that less favourable treatment is concerned with "whether the technical
regulation at issue modifies the conditions of competition in the market of the regulating Member
to the detriment of the group of imported products vis-à-vis the group of like domestic
products."168 The parties also recognize that establishing such detrimental impact does not suffice
to establish less favourable treatment under Article 2.1; it must additionally be shown that any
such detrimental impact does not stem exclusively from legitimate regulatory distinctions.169
7.62. Accordingly, we first assess whether th e amended COOL measure has detrimental impact,
and then proceed to inquire whether any such detrimental impact stems exclusively from
legitimate regulatory distinctions.
7.5.4.1 Detrimental impact
7.63. The complainants claim
170 that the amended COOL measure has maintained and, in fact,
increased the original COOL measure's detrimental impact on the competitive opportunities of
imported livestock in comparison with like US products. 171 The United States accepts that the
amended COOL measure was not intended to "remove [the original COOL measure's] detrimental
impact on imports"
172; at the same time, it rejects the suggestion that there is any increase in
detrimental impact.

172 According to the United States, "to comply with the DSB recommendations and rulings, the
United States could either remove the detrimental impact on imports or ensure that any detrimental impact
stems exclusively from a legitimate regulatory distinction. The 2013 Final Rule implements the second option –
it addresses the DSB recommendations and rulings by ensuring that any detrimental impact stems exclusively
from a legitimate regulatory distinction." United States' response to Panel question No. 18 (emphasis original).
WT/DS384/RW • WT/DS386/RW

7.64. The original panel held that "[t]he [original] COOL measure create[d] a de facto incentive in
favour of domestic, and to the detriment of imported, livestock in the particular circumstances of
the US livestock and meat market"
173, and "reduce[d] the competitive opportunities of imported
livestock relative to domestic livestock."174 On this basis, the original panel "f[ou]nd that, in the
context of the muscle cut labels, the COOL measure create[d] an incentive in favour of processing
exclusively domestic livestock and a disincentive against handling imported livestock." 175
Accordingly, the original panel "also f[ou]nd that, in the context of muscle cut labels,
the COOL measure de facto discriminate[d] against imported livestock by according less
favourable treatment to Canadian cattle and hogs, and to Mexican cattle, especially Mexican feeder
cattle, than to like domestic livestock."
176 As regards the ground meat label, the original panel
"f[ou]nd that the complainants have not demonstrated that the ground meat label under the
[original] COOL measure results in less favourable treatment for imported livestock."177
7.65. The original panel's Article 2.1 finding concerning the ground meat label was not challenged
on appeal. Regarding the muscle cut labels, the Appellate Body upheld the original panel's finding
that the COOL measure resulted in less favourable treatment for imported livestock than for like
domestic livestock. 178 However, the Appellate Body declared the original panel's legal analysis
under Article 2.1 to be "incomplete", as the original panel "should have continued its examination
[beyond assessing detrimental impact] and determined whether … the detrimental impact stems
exclusively from a legitimate regulatory distinction". 179 Thus, while the Appellate Body endorsed
the original panel's approach 180 and conclusion 181 regarding the detrimental impact aspect of the
legal test, it also determined that the detrimental impact did not stem exclusively from a
legitimate regulatory distinction.182 Under the circumstances, the Appellate Body ultimately upheld
the original panel's finding that the COOL measure is inconsistent with Article 2.1 of the TBT
Agreement, but for different reasons.
183
7.66. We shall follow the original panel's approach to detrimental impact 184 – focusing on the
muscle cut labels. 185 As summarized by the Appellate Body, this approach involved three main
legal considerations:
a. as a "starting point" 186, whether the different categories of muscle cut labels under the
COOL measure accord different treatment to imported livestock;
b. whether the COOL measure involves segregation and, consequently, differential costs for
imported livestock; and
c. whether, through the compliance costs involved, the COOL measure creates any
incentive to process domestic livestock, thus reducing the competitive opportunities of
imported livestock.
187
7.67. In addition, the original panel examined the parties' evidence of actual trade effects – albeit
stating that analysing actual trade effects was not indispensable for disposing of the complainants'

178 Appellate Body Reports, US – COOL, para. 350.
179 Appellate Body Reports, US – COOL, para. 293.
180 The Appellate Body held that the original panel's "legal approach to assessing detrimental impact was
correct." Appellate Body Reports, US – COOL, para. 293.
181 The Appellate Body found that "the [original p]anel [had] properly examined whether the [original]
COOL measure modifie[d] the conditions of competition in the US market to the detriment of imported
livestock." Appellate Body Reports, US – COOL, para. 291. See also ibid. para. 292.

approach to assessing detrimental impact, see Appellate Body Reports, US – COOL, paras. 257-264.

the muscle cut labels in this compliance dispute. See section 7.4 above.

Article 2.1 claims. Given that the Appellate Body di d not find error in the original panel's approach
to evidence on actual trade effects in the original dispute 188, we review the extensive evidence
submitted on the same matter in this compliance dispute.
7.5.4.1.1 Different treatment
7.68. The original panel began by reviewing th e statutory definitions of the four muscle cut
labels.189 It then addressed the commingling flexibili ty between products eligible for Labels A
and B.190 The original panel observed that under the original COOL measure, "imported livestock is
ineligible for the label reserved for meat from exclusively US-origin livestock, whereas in certain
circumstances meat from domestic livestock is eligible for a label that involves imported
livestock."
191 The original panel considered this difference only as "the starting point" 192 of its
analysis because " different treatment" of imported products is "not necessarily inconsistent … as
long as the treatment by the measure is 'no less favourable'."193
7.69. On appeal, the Appellate Body confirmed its earlier finding that "'[a] formal difference in
treatment between imported and like domestic products is … neither necessary, nor sufficient, to
show a violation' of the national treatment obligation." 194 It noted that the original panel's
statement on different treatment is not a "finding or a legal conclusion" 195, but "merely … a
passing observation regarding the extent to which the COOL measure de jure treat[ed] imported
livestock differently than domestic livestock."196
7.70. As explained 197, the 2013 Final Rule removed the commingling flexibility, which allowed
Category A products to carry Label B in certain circumstances. Thus, the basis for observing any
formally different treatment of domestic and impo rted livestock under the original COOL measure
is not maintained under the amended COOL measure.
7.71. We do not need to explore further the ex istence of any formally different treatment under
the amended COOL measure. As in the original dispute, "the complainants are not contesting any
formal difference in the treatment accord ed to domestic and imported livestock per se"; they
claim
198 "de facto less favourable treatment to imported livestock."199
7.72. In any event, any further assessment of formally different treatment could only serve as a
starting point for our less favourable treatment analysis. It would lack any "direct… connect[ion]"
or implication for our ultimate finding on whether or not the amended COOL measure entails de
facto discrimination.200

189 See Panel Reports, US – COOL, paras. 7.284 and 7.286.
190 Panel Reports, US – COOL, para. 7.295. The original panel noted the commingling flexibility between
Label B and C products and that "Labels B and C may overlap in practice since 'the countries of origin may be
listed in any order' on Label B." However, the original panel held that "flexibilities between Labels B and C have
limited relevance for the complainants' claims under Article 2.1", and it chose to "focus … [on] the distinction
between Label A, defined as 'United States Country of Origin' in the COOL statute, and the rest of the labels,
which all involve livestock with an imported element." Panel Reports, US – COOL, paras. 7.288

7.73. We turn to whether the amended COOL measure involves de facto 201 less favourable
treatment, including detrimental impact. In analysing this matter, we are mindful of the
Appellate Body's guidance in the original dispute:
[W]here a technical regulation does not discriminate de jure, a panel must determine
whether the evidence and arguments adduced by the complainant in a specific case
nevertheless demonstrate that the operation of that measure, in the relevant market,
has a de facto detrimental impact on the group of like imported products. A panel's
analysis must take into consideration the totality of the facts and circumstances
before it, including any implications for competitive conditions discernible from the
design and structure of the measure itself, as well as all features of the particular
market at issue that are relevant to the measure's operation within that market.
In this regard, " any adverse impact on competitive opportunities for imported
products vis-à-vis like domestic products that is caused by a particular measure may
potentially be relevant" to a panel's assessment of less favourable treatment under
Article 2.1.
202
7.5.4.1.2 Costs, segregation, and recordkeeping
7.5.4.1.2.1 Costs
203
7.74. The original panel started its analysis of whether there is de facto detrimental impact by
establishing that – according to the 2009 Final Rule – the original COOL measure involved
compliance costs.
204
7.75. Addressing the United States' arguments that "any regulation potentially involves costs" 205
and that these costs "may [be] differential for different types of market participants" 206, the
original panel pointed out that "it is not the costs of the COOL measure in itself that the
complainants contest."
207 It added that "Article 2.1 is concerned with the equality of competitive
conditions between domestic and imported produc ts", and "no competitive disadvantage shall be
accorded to imported products as compared to like domestic products."208 According to the original
panel, "[a] cost resulting from a (technical) regulation may qualify as a competitive disadvantage
if it is incurred only by imported and not like domestic products."209
7.76. The same analytical approach applies to the amended COOL measure and this compliance
dispute. Like its predecessor 210, the 2013 Final Rule has a dedicated section on the costs of the
amended COOL measure. 211 And, as in the 2009 Final Rule 212, the USDA "recognizes that

201 The original panel held that "it would be incongruous to interpret Article 2.1 of the TBT Agreement as
excluding de facto discriminatory treatment." Panel Reports, US – COOL, para. 7.301. On appeal, the
Appellate Body confirmed that "[a]s under Article III:4, the national treatment obligation of Article 2.1
prohibits both de jure and de facto less favourable treatment. That is, 'a measure may be de facto inconsistent
with Article 2.1 even when it is origin-neutral on its face.'" Appellate Body Reports, US – COOL, para. 269
(footnotes omitted) (citing Appellate Body Reports, US – Clove Cigarettes, para. 175; and US – Tuna II
202 Appellate Body Reports, US – COOL, para. 286 (footnote omitted) (citing Appellate Body Report, US
– Tuna II (Mexico), para. 225 (emphasis original)).
203 In reviewing the costs of the amended COOL measure, we do not address recordkeeping and
segregation requirements under other measures not at issue in this compliance dispute, e.g. food safety
measures. Further, we do not address how such other measures, whether mandatory or voluntary,
might impact or reduce the compliance burden of the amended COOL measure.
204 The original panel held that "costs of compliance with the requirements [of the original COOL
measure] arise at every stage of the livestock and meat supply chain, and … these costs increase as livestock
and meat move downstream in the chain." Panel Reports, US – COOL, para. 7.310.
210 See "Analysis of Benefits and Costs", 2009 Final Rule, pp. 2682 et seq. See also Panel Reports, US –
COOL, paras. 7.304-7.308.
211 See "Analysis of Benefits and Costs", 2013 Final Rule, pp. 31377 et seq.
WT/DS384/RW • WT/DS386/RW

additional costs will be borne by industry partic ipants as they comply with the requirements of
th[e 2013 F]inal [R]ule".213
7.77. However, as in the original dispute, it is "not the costs of the COOL measure in itself that
the complainants contest." 214 Accordingly, we follow the original panel and turn to whether
"the costs of the [amended] COOL measure are higher for imported than for domestic livestock".
As explained below, this requires assessing whether the amended COOL measure involves215 – and
possibly increases – segregation of meat and livestock according to origin as well as the
implications of the amended COOL measure for recordkeeping burdens.
7.5.4.1.2.2 Segregation216
7.78. Given the nature and limited extent of relevant changes to the original COOL measure, the
original panel's analysis of segregation remains generally applicable to the amended COOL
measure.
7.79. Like its predecessor, the amended COOL measure "does not explicitly require segregation,
let alone the segregation of domestic and imported livestock." 217 At the same time, under the
2013 Final Rule it remains "necessary ... to ensure label information accurately reflects the origin
of muscle cut covered commodities in accordance with the intent of the statute." 218 The
2013 Final Rule is categorical that, as a basic requirement, " all origin designations for muscle cut
covered commodities slaughtered in the United States must specify the production steps of birth,
raising and slaughter of the animal from which the meat is derived that took place in each country
listed on the origin designation."219
7.80. The COOL statute continues to require th at "[a]ny person engaged in the business of
supplying a covered commodity to a retailer … provide information to the retailer indicating the
country of origin of the covered commodity." 220 In addition, the original COOL measure's
recordkeeping requirements and sanctions for violating these221 remain unchanged.222
7.81. Thus, the original panel's finding that that the original COOL measure "prescribes an
unbroken chain of reliable country of origin information with regard to every animal and muscle
cut"
223 remains valid for the amended COOL measure. In fact, the 2013 Final Rule refers to the

212 According to the 2009 Final Rule, "firms and establishments throughout the supply chain for affected
commodities will incur costs associated with the implementation of COOL. This includes producers,
intermediaries, and retailers." 2009 Final Rule, p. 2680 (cited in Panel Reports, US – COOL, para. 7.303).
213 2013 Final Rule, p. 31375. Likewise, the USDA "recognizes that additional costs will be borne by
industry participants." 2013 Final Rule, p. 31374.
216 The Appellate Body "understood the [original p]anel to have used the term 'segregation' to
encompass a broad range of activities, including physically segregating animals into different pens or fields or
identifying each animal through the use of ear tags or other physical markings, temporally segregating animals
by processing livestock of different origins on different days or at different times, and segregating animals
completely in the sense of choosing to process only livestock of a single origin." Appellate Body Reports, US –
COOL, para. 302 (footnotes omitted). We use the term "segregation" in the same sense in these Reports.

need for, and existing processes 224 to, "transfer information from one level of the supply chain to
the next."225
7.82. The original panel's findings on how to ensure the unbroken chain of reliable country of
origin information 226 necessitated by the original COOL measure remain valid for the amended
COOL measure. The COOL statute continues to prohibit USDA from imposing a "traceability
program"227 through "a mandatory identification system to verify the country of origin of a covered
commodity."228 Further, the COOL statute continues to limit the recordkeeping requirements for
retailers and their suppliers to "records maintained in the normal conduct of the business of such
person, including animal health papers, import or customs documents, or producer affidavits" 229,
and it continues to explicitly prohibit USDA from requiring retailers and suppliers to maintain any
"additional records".
230 As summarized by the 2013 Final Rule:
the existing COOL regulations already require retailers to maintain records and other
documentary evidence upon which they have relied to establish a covered
commodity's country or countries of origin. Similarly, any person directly or indirectly
engaged in the business of supplying a covered commodity to a retailer, including
wholesalers, must make available information to the buyer about the country(ies) of
origin of the covered commodity. Thus, to comply with existing COOL regulations,
wholesalers must already have distribution systems to allow for the tracking of
COOL-related information for invoices and manifests and receiving procedures to
verify the origin information received from packers and processors. This final rule does
not alter those requirements … .
231
7.83. The original panel held that "a practical way to ensure that the chain of reliable information
on country of origin required by the COOL meas ure remains unbroken is the segregation of meat
and livestock according to origin as defined by the COOL measure." 232 Despite the parties'
disagreement, the original panel concluded that "for all practical purposes, the COOL measure
necessitates segregation of meat and livestock according to origin." 233 This finding was upheld on
appeal.234
7.84. The same conclusion continues to apply to the amended COOL measure, which has the
same features that led the original panel to reach its conclusion regarding segregation. In fact, the
2013 Final Rule refers to segregation as a fact: "the [2003] regulatory impact analysis accounted
for the fact that animals and products would need to be segregated to enable labeling of muscle
cut covered commodities by country of origin."
235
7.85. As with the original COOL measure236, various United States entities and market participants
have stated that the amended COOL measure will necessarily lead to segregation in the meat

224 For instance, the 2013 Final Rule points out that "[p]rocesses currently in place to transfer
information from one level of the supply chain to the next should be sufficient to accommodate the additional
requirements of this rule." 2013 Final Rule, pp. 31376-31377.
225 2013 Final Rule, p. 31373. Further, the 2013 Final Rule states that it "does not lessen any existing
flexibility in how required country of origin information is currently conveyed along the supply chain."
2013 Final Rule, p. 31375.
226 See Panel Reports, US – COOL, para. 7.319.

231 2013 Final Rule, p. 31374. See also ibid. pp. 31373 and 31382.
234 The Appellate Body found that "the Panel did not act inconsistently with its duties under Article 11 of
the DSU in finding that, 'for all practical purposes, the COOL measure necessitates segregation of meat and
livestock according to origin, even though this segregation is subject to certain flexibilities'." Appellate Body
Reports, US – COOL, para. 310.
235 2013 Final Rule, p. 31379. Further, the 2013 Final Rule refers to "costs … of activities such as
segregation", and notes that, "[a]s at the intermediary level, retailers may incur additional costs for
segregation" as a result of the removal of the commingling flexibility. 2013 Final Rule, p. 31380.

supply chain.237 Indeed, the United States itself seems to recognize that, like its predecessor, the
amended COOL measure involves segregation.238
7.86. Accordingly, like the original panel 239, we conclude that for all practical purposes, the
amended COOL measure necessitates segregation of meat and livestock according to origin.
7.5.4.1.2.3 Increased segregation under the amended COOL measure
7.87. The parties disagree on the amended COOL me asure's impact on segregation. In particular,
the United States contests the complainants' argument that the amended COOL measure involves
more segregation than the original COOL measure.
7.88. As noted 240, the COOL measure never formally pr escribed segregation. However, the
2013 Final Rule introduced three potentially relevant changes:
a. point-of-production labelling, i.e. the requir ement that Labels A, B, and C show the
country(ies) where each production step, namely birth, raising, and slaughter, has taken
place241;
b. the removal of the commingling 242 and country order flexibilities 243 of the original COOL
measure; and
c. the amended coverage of Label D.
Point-of-production labelling
7.89. As noted244, one of the main changes under the amended COOL measure is the requirement
t h a t L a b e l s A , B , a n d C i n d i c a t e t h e c o u n t r y o f e a c h p r o d u c t i o n s t e p ( b o r n , r a i s e d , a n d
slaughtered).
245 In the USDA's words, point-of-production labelling means that "muscle cut
covered commodity COOL information will need to be augmented to provide the additional specific
origin information required by th[e 2013 Final R]ule."246 More specifically, "information available to
consumers at retail will need to be augmented to include information on the location in which the
three major production steps occurred."
247

237 See para. 7.135 below.
238 According to the United States, "with regard to the allegation that the 2013 Final Rule 'compel[s]
segregation,' it is clear that the only companies that will have to change any internal procedures are those that
were already commingling. Companies that already completely segregated A, B, and C livestock (and the
resulting meat products) are, of course, unaffected by this change in the regulations." United States' first
written submission, para. 114 (footnotes omitted, emphasis original). Further, according to the United States,
"it is impossible to understand why the complaining parties allege that the 2013 Final Rule is increasing
segregation in such a meaningful way as to affect their producers' market access in the United States. By
making such arguments, the complaining parties appear to allege that the original panel was wrong to find that
the 2009 Final Rule 'necessitated' segregation, and that, in fact, the commingling flexibility so reduced the
need for segregation for the companies that purchased Canadian and Mexican livestock that it could not be
concluded that the 2009 Final Rule 'necessitated' segregation for those companies." United States' first written
submission, paras. 115-116 (emphasis original). The United States adds that "to credit those arguments based
on speculation of business impacts would require the compliance Panels to find that the original panel's finding
that the 2009 Final Rule 'necessitated' segregation was wrong. The complainants have provided no basis for
the compliance Panels to revisit and reverse findings adopted in the original proceeding." United States' first
written submission, para. 119.

7.90. A closer look at Labels A-C is necessary for assessing whether, in practice, "provid[ing]
consumers with more specific information" 248 on these labels increases the number of distinct
labels. We isolate point-of-production labelling to assess whether different origin muscle cuts that
could carry a uniform origin label under the original COOL measure would need to carry more,
distinct labels under the amended COOL measure. As the original panel found, more origins and
labels means more segregation.
249

248 2013 Final Rule, p. 31367.
249 In the words of the original panel, "it is evident that the more origins and the more types of muscle
cut labels involved, the more intensive the need for segregation throughout the livestock and meat supply and
distribution chain." Panel Reports, US – COOL, para. 7.331. See also ibid. para. 7.346. The Appellate Body
upheld this finding. Appellate Body Reports, US – COOL, para. 345.
WT/DS384/RW • WT/DS386/RW

Label A
7.91. As regards Label A, the definition of origin is unchanged; Label A merely needs to be more
detailed under the amended COOL measure and state, instead of "Product of the U.S." 250,
"Born, Raised, and Slaughtered in the United States" 251. Muscle cuts from exclusively US-born,
-raised and -slaughtered livestock shall carry labels with information about these production steps;
however, Category A muscle cuts may continue to carry a uniform Label A.
7.92. In brief, Label A shall be more detailed, but it may remain a uniform label. As shown in
Table 3 below, point-of-production labelling in and of itself does not increase the number of labels
for Category A muscle cuts, and thus does not lead to increased segregation.

Notes to Table 3: The first label is taken from the

para. 7.100. The second label is taken from the 2013 Final Rule,
§ 65.300(d).

Label B
7.93. Label B may involve livestock of a single foreign origin – in addition to raising 252 and
slaughter in the United States. For instance, Label B may be used for muscle cuts derived from
animals (i) born in Canada and (ii) raised and sl aughtered in the United States. Under the original
COOL measure, muscle cuts from livestock "born in Country X … , raised and slaughtered in the
United States"
253 ("and … not derived from animals imported for immediate slaughter" 254) could be
designated as "Product of the United States, Country X … ." 255 Under the amended COOL measure,
t h e s a m e t y p e o f m u s c l e c u t s w o u l d n o w b e d e s i g n a t e d " B o r n i n C o u n t r y X , R a i s e d a n d
Slaughtered in the United States".256
7.94. Thus, like for Label A, the amended COOL measure requires more information on Label B,
but Category B muscle cuts from livestock born in a single foreign country, and raised and
slaughtered in the United States may continue to carry a uniform label. As shown in Table 4 below,
point-of-production labelling does not increase th e number of labels and, hence, segregation for

250 See 2009 Final Rule, p. 2668; and Panel Reports, US – COOL, para. 7.100.
251 2013 Final Rule, § 65.300(d).
252 A distinct characteristic of Category B origin under the 2013 Final Rule is that animals in that origin
category need to be not only slaughtered but also raised in the United States. Otherwise, muscle cuts derived
from such animals would be imported for immediate US slaughter, and thus qualify for Label C. This is also
confirmed by the multiple countries of raising flexibility, applicable to Label B, and allowing for omitting the
"other" country or countries of raising but not the United States. 2013 Final Rule, § 65.300(e). See also the
examples of Label B taken from the amended COOL measure in Table 2, each of which mentions US raising.

Category B muscle cuts of a single foreign origin in addition to raising and slaughter in the
United States (Scenario B1).
7.95. This is also applicable to Category B muscle cuts from livestock of a single foreign origin,
born and also raised in the foreign country of birth, i.e. muscle cuts from livestock (i) born and
raised in Country X; and (ii) raised and slaughtered in the United States. In the absence of point-
of-production labelling, these muscle cuts could also carry the "Product of the United States,
Country X … "
257 label under the original COOL measure. 258 Under the amended COOL measure,
these muscle cuts could now carry the "Born in Country X, Raised and Slaughtered in the
United States"259 label because of the multiple countries of raising flexibility. 260 In light of this
flexibility261, point-of-production labelling does not result in more segregation for Category B
muscle cuts raised in both the foreign country of birth and in the United States.

Notes to Table 4: The first label is taken from the

from the 2013 Final Rule, p. 31368, and § 65.300(e), including the
multiple countries of raising flexibility.

7.96. There is also the possibility of Category B muscle cuts being derived from livestock of
multiple foreign origins in addition to US raising and slaughter. For instance, the 2009 Final Rule
addressed muscle cuts from livestock "born in Country X or (as applicable) Country Y, raised and
slaughtered in the United States"
262 ("and … not derived from animals imported for immediate
slaughter"263).

257 2009 Final Rule, § 65300(e)(1).
258 This would not change with the multiple countries of raising flexibility of the original COOL measure –
given that, despite US raising "tak[ing] precedence" over raising in the foreign country of birth, this latter
country would still need to be mentioned on the label. See 2009 Final Rule, pp. 2659-2662, and section 7.3.3.3
above.
259 2013 Final Rule, § 65300(e).
260 According to the 2013 Final Rule, "[i]f an animal is raised in the United States as well as another
country (or multiple countries), the raising occurring in the other country (or countries) may be omitted from
the origin designation except if the animal was imported for immediate slaughter … or where by doing so the
muscle cut covered commodity would be designated as having United States country of origin."
2013 Final Rule, § 65.300(e). See section 7.3.3.3 above.
261 In any event, as the 2013 Final Rule explains in regard to both the original and amended forms of
this flexibility, "it is understood that an animal born in another country will have been raised at least a portion
of its life in that other country." 2013 Final Rule, p. 31368.

7.97. Under this scenario (Scenario B2), the Category B muscle cuts in question originate from
both (i) livestock born in Country X, and raised and slaughtered in the United States, as well as
(ii) livestock born in Country Y, and raised and slaughtered in the United States. This scenario
therefore represents a combination of livestock from two different foreign countries of origin,
which fall within Category B.
264
7.98. According to the 2009 Final rule, the two types of muscle cuts in this scenario could be
designated as "Product of the United States, Country X, and … Country Y." Conversely, under the
2013 Final Rule, these two types of muscle cuts would need to carry distinct labels to reflect their
different countries of origin.
7.99. As shown in Table 5 below, segregation increases as a result of point-of-production labelling
under this scenario (Scenario B2) – even taking into consideration the multiple countries of raising
flexibility under the amended COOL measure.265

264 2009 Final Rule, § 65.300(e)(1). In a certain way, this was a type of commingling. Commingling was
more closely associated with scenarios of mixing covered commodities of different origin categories (e.g.
muscle cuts Category A with B, Category B with C, respectively). See 2013 Final Rule, footnote 7; and footnote
99 above. However, the 2009 Final Rule defines "commingled covered commodities" as "covered commodities
(of the same type) presented for retail sale in a consumer package that have been prepared from raw material
sources having different origins." 2009 Final Rule, § 65.125 (emphasis added). Arguably, this could also cover
muscle cuts of different origins within the same origin category.

7.100. Another multiple foreign-origin scenario (Scenario B3) might entail Category B muscle cuts
from livestock raised in more than one foreign country in addition to being raised (and
slaughtered) in the United States. This would involve livestock (i) born in Country X; (ii) raised in
Country X, Country Y, and the United States; and (iii) slaughtered in the United States. Arguably,
absent point-of-production labelling, the Label B und er this scenario could also read "Product of
the United States, Country X, and … Country Y"
266 under the original COOL measure.267
7.101. As shown in Table 6 below, the same type of muscle cuts could also carry a uniform but
more detailed Label B under the amended COOL measure (Scenarios B3a and B3b taken
separately).268
7.102. The situation is different regarding Category B muscle cuts from livestock (i) born in two
different foreign countries; (ii) raised in the same two foreign countries and the United States; and
(iii) slaughtered in the United States. Taking the example of a Category B muscle cut of US,
Canadian, and Mexican origin, a uniform 'North American' label ("Product of the United States,
Canada, and Mexico") could have been affixed on all of these muscle cuts under the original COOL
measure. This is no longer possible under the amended COOL measure's point-of-production
labelling. As shown in Table 6, distinct labels for these Category B muscle cuts would need to be
affixed according to where each production step took place (Scenarios B3a and B3b taken
together)
269 – even taking into consideration the multiple countries of raising flexibility under the
amended COOL measure.270

266 2009 Final Rule, § 65.300(e)(1). Again, this would be a type of intra-Category commingling in the
manner described above. See footnote 264 above.
267 As noted, this would not change with the multiple countries of raising flexibility of the original COOL
measure given that, despite US raising "tak[ing] precedence" over raising in the foreign country of birth, this
latter country would still need to be mentioned on the label. See 2009 Final Rule, pp. 2659-2662, and section
7.3.3.3 above.
268 This label could show each country of raising (e.g. "Born in Country X, Raised in Country X, Country
Y and the United States, and Slaughtered in the United States") or only the United States, depending on
whether the multiple countries of raising flexibility is being used on Label B.
269 This also applies to muscle cuts from US-born and -slaughtered animals raised in both the
United States and a foreign country. Under the original COOL measure, the relevant Label B would read
"Product of the United States and Country X". The same Label B could cover Category B muscle cuts involving
the same two countries but for different production steps, e.g. muscle cuts born in Country X, and raised and
slaughtered in the United States. Point-of-production labelling means that these two types of muscle cuts
would need to carry distinct labels under the amended COOL measure. In particular, muscle cuts from US-born
and -slaughtered animals raised in both the United States and a foreign country would carry the label "Born
and Raised in the United States, Raised in Country X, Slaughtered in the United States." 2013 Final Rule,
p. 31368.

Label C
7.103. Like for Label B, for Label C we address scenarios involving livestock with single and
multiple foreign origins which, pursuant to the Category C definition, are imported for immediate
slaughter into the United States.
7.104. For single foreign-origin Category C muscle cuts, under the amended COOL measure,
Label C would read "Born and Raised in Country X, Slaughtered in the United States"
271 instead of
"Product of Country X and the United States". 272 Despite the more detailed information,
Category C muscle cuts of a single foreign origin can thus continue to carry a uniform label under
the amended COOL measure. As shown in Table 7 below, there is no increase in the number of
labels or in segregation for single foreign-origin Category C muscle cuts as a result of point-of-
production labelling.

from the 2013 Final Rule, § 65.300(e) and pp. 31368-31369.

7.105. Turning to Category C muscle cuts of multiple foreign origins, muscle cuts from two
different single foreign-origin Category C animals had to carry two distinct labels under the original
COOL measure.
273 Muscle cuts from livestock born and raised in Canada, and muscle cuts of
livestock born and raised in Mexico (both imported for immediate slaughter in the United States)
would carry two distinct labels under the amended COOL measure.

271 2013 Final Rule, § 65.300(e) and pp. 31368-31369.
272 2009 Final Rule, § 65.300(e)(3).
273 We do not think that a single 'North American' Label C could be affixed on the two different single-
origin Category C livestock of Scenario C2 under the original COOL measure. The original COOL measure
defined "commingled covered commodities" as "covered commodities (of the same type) presented for retail
sale in a consumer package that have been prepared from raw material sources having different origins."
2009 Final Rule, § 65.125. Although this might cover muscle cuts of different origins within the same origin
category, we do not think this was possible for Category C. Unlike for Label B, the original COOL measure
determines Label C by reference to single foreign origin as "Product of Country X and the United States".

2009 Final Rule, § 65.300(e)(3). Further, the COOL statute foresees Label C of a single foreign origin by
prescribing that labels on muscle cuts imported for immediate slaughter "shall designate the origin … as (i) the
country from which the animal was imported; and (ii) the United States." COOL statute, § 1638a(2)(c). In any
event, even if this type of intra-category commingling was possible for two different single foreign-origin
Category C muscle cuts, point-of-production labelling means that under the amended COOL measure, these
two types of muscle cuts need to carry two different Category C labels depending on the animal's place of
birth.

7.106. As shown in Table 8 below, no increase in the number of labels or in segregation is
involved in this scenario (Scenario C2) as a result of point-of-production labelling.

7.107. Another multiple foreign-origin scenario might entail Category C muscle cuts from livestock
(i) born and raised in a foreign country; (ii) also raised in a second foreign country; and
(iii) imported for immediate slaughter to the United States. Using the same two foreign countries,
there are four potential scenarios depending on whether the animals were born in Country X or Y,
and in what sequence they were raised in these two countries (Scenarios C3-C6).
7.108. The sequence of countries of raising might be relevant because of the parties'
disagreement on which countries of raising need to be labelled for Category C muscle cuts from
livestock raised in more than one country.
274 The 2013 Final Rule requires, as a general rule, that
"Muscle Cut Covered Commodities of Multiple Countries of Origin from Animals Slaughtered in the
United States" be "labelled to specifically identify the production steps occurring in each
country".
275 Specifically, "the origin designation for muscle cut covered commodities derived from
animals imported for immediate slaughter [i.e. Category C muscle cuts] … is required to include
information as to the location of the three production steps."
276 However, under the
2013 Final Rule, "the country of raising for animals imported for immediate slaughter … shall be
designated as the country from which they were imported (e.g. 'Born and Raised in Country X,
Slaughtered in the United States')."
277 Further, the COOL statute foresees Category C labels listing
a single foreign origin by prescribing that labels on muscle cuts imported for immediate slaughter
"shall designate the origin … as (i) the country from which the animal was imported; and (ii) the
United States."278
7.109. If the 2013 Final Rule precludes countrie s other than the country of export from being
listed as the country of raising, there are more labels and thus more segregation under the
amended COOL measure for Scenarios C3-C6. This is illustrated in the second to bottom row of
Table 9 below.
7.110. Alternatively, if the 2013 Final Rule permits countries of raising other than the country of
immediate import on Label C – and provided the countries of raising do not have to be listed in
strict chronological order – the label could be arranged so as to retain the same number of distinct

Conclusion
7.111. In light of the above, we conclude that point-of-production labelling, as prescribed by the
amended COOL measure, in and of itself increases the number of distinct labels for:
a. Category B muscle cuts of different foreign origins (Scenario B2 – Table 5) – irrespective
of the multiple countries of raising flexibility under the amended COOL measure;
b. Category B muscle cuts of different, multiple foreign origins (Scenarios B3a and B3b
taken together – Table 6) – irrespective of the multiple countries of raising flexibility
under the amended COOL measure; and
c. Category C muscle cuts of animals born in a foreign country, raised in that and another
foreign country, and imported into the United States for immediate slaughter (Scenarios
C3-C6 taken together – Table 9) – if only th e country of immediate import can be shown
as the country of raising on the label.280
7.112. As mentioned, under the amended COOL measure more labels still mean more
segregation.281 As a result of the unchanged requirement for an unbroken chain of reliable country
of origin information, segregation of the downstream product (muscle cuts) necessarily entails
segregation of the upstream product (livestock).
282 The increase in the number of distinct labels
for the above three types of muscle cuts also entails more segregation for the relevant types of
muscle cuts and the originating livestock.
7.113. We also conclude that, compared with the original COOL measure, point-of-production
labelling in and of itself does not affect the number of labels for other types of Category B and C
muscle cuts, and for Category A muscle cuts in general. In other words, point-of-production
labelling under the amended COOL measure does not directly increase or decrease segregation for
these types of muscle cuts and the originating livestock.

280 As we are reviewing differences in the design and structure of the original and amended COOL
measures to assess increased segregation, we reach these conclusions without assessing the probabilities of
the various hypothetical scenarios. We also disregard the abbreviation flexibilities under the original and
amended COOL measures, as these have no direct implications for understanding whether there is an
increased number of distinct labels.
281 See Panel Reports, US – COOL, paras. 7.331 and 7.346.
282 According to the original panel, "the COOL measure requires labelling of meat based on the origin of
an animal from which meat is derived, and upstream stages of livestock and meat production are directly
relevant for determining the origin of meat." Panel Reports, US – COOL, para. 7.315. See also ibid.
para. 7.316. As the USDA noted in the context of the original COOL measure, "[p]roducers of cattle[ and] hogs
… while not directly covered by [the 2009 Final Rule], will nevertheless be affected because covered meat
commodities are produced from livestock." 2009 Final Rule, p. 2695.
WT/DS384/RW • WT/DS386/RW

Removal of the two flexibilities under the original COOL measure
7.114. In the original dispute, commingling between products eligible for Labels A and B, and
Labels B and C, respectively, was found to have only partially mitigated the segregation
necessitated by the original COOL measure.
283 The flexibility of listing countries of origin in any
order on Category B and commingled muscle cuts had a similar effect.284
7.115. As shown in Table 2, these two flexibilitie s – applied cumulatively – meant that under the
original COOL measure a uniform label could cover muscle cuts from livestock of possibly three
different origins:
a. muscle cuts from livestock born, raised, and slaughtered in the United States;
b. muscle cuts from livestock raised, and slaughtered in the United States, and born
elsewhere; and
c. muscle cuts from livestock imported into the United States for immediate slaughter after
being born and raised elsewhere.
7.116. Put differently, as a combined result of the commingling and country order flexibilities, it
was possible to affix a uniform label on the followin g four different types of Category A, B, and C
muscle cuts:
a. commingled muscle cuts from Category A and B animals;
b. muscle cuts from Category B animals;
c. commingled muscle cuts from Category B and C animals; and
d. muscle cuts from Category C animals;
7.117. This is shown in the shaded parts on the left-hand side of Table 10 below, using the
2009 Final Rule's label example "Product of Canada, U.S.".285
7.118. This diverse applicability of the same, uniform label was due to the commingling and
country order flexibilities under the original CO OL measure. As these two flexibilities are now
removed, the four specific types of muscle cuts (shaded on the left) derived from the three
different origins of livestock (shaded in the middle) must always carry distinct labels under the
amended COOL measure, as shown (shaded on the right) in Table 10 below.

283 Panel Reports, US – COOL, para. 7.327. See also Appellate Body Reports, US – COOL, para. 310.
284 As the Appellate Body held, "[m]eat derived from animals born outside the United States but raised
and slaughtered in the United States (Category B meat) must be labelled as a product of the United States and
the foreign country in which the animal was born, and the countries of origin may be listed in any order. For
meat derived from animals imported into the United States for immediate slaughter (Category C meat), labels
must indicate all of the countries of origin of the animal, but cannot list the United States first. Because the
countries of origin for Category B meat can be listed in any order, the labels for Categories B and C meat could
look the same in practice." Appellate Body Reports, US – COOL, para. 245.
285 2009 Final Rule, p. 2661. As the country order flexibility did not apply to non-commingled Label C
muscle cuts under the 2009 Final Rule, the "Product of U.S., Canada" label could not be affixed to such muscle
cuts. See 2009 Final Rule, p. 2662 and § 65.300 (e)(4). See also Panel Reports, US – COOL, para. 7.697;
Appellate Body Reports, US – COOL, para. 245. In any event, in light of the country order flexibility, the
"Product of U.S., Canada" label could be affixed to: (i) commingled Category A and B muscle cuts; (ii) Label B
muscle cuts; and (iii) commingled Category B and C muscle cuts.

labels on the right follow the general provisions of the amended COOL measure.

7.119. The same conclusion applies also to th e three main types of livestock and muscle cut
origins in the US market – namely, exclusively US -origin (i.e. Category A) muscle cuts, and single
foreign-origin muscle cuts of Categories B and C (i.e. muscle cuts from US-slaughtered Mexican
feeder and Canadian fed cattle) – taken together.
7.120. Due to the commingling and country order flexibilities under the original COOL measure,
a uniform 'North American' label ("Product of Canada, Mexico and the United States") could
previously be affixed on all of these muscle cuts . Conversely, as shown in Table 11 below, absent
the commingling and country order flexibilities, these three types of muscle cuts need to carry
three distinct labels under the amended COOL measure.

7.121. The parties disagree on the extent of the removed commingling flexibility. According to the
Mexico, in practice many operators in the United States commingled.
286 According to Canada, the
slaughterhouses that were accepting Canadian cattle and hogs under the 2009 Final Rule likely
took advantage of the commingling flexibility, whereas under the amended COOL measure
"when Canadian cattle and hogs are processed at th ese slaughterhouses, they will no longer be
eligible for commingling.
287 Conversely, the United States contends that only few individual meat
processors were commingling. 288 The parties held inverted positions on the prevalence of
commingling in the original dispute.289
7.122. The original panel reviewed evidence on the practice and extent of commingling 290,
and concluded that "[a]lthough it appears that some commingling is taking place, it is difficult to
establish its precise extent."
291 Based on a letter from the American Meat Institute referenced by
all three parties in the original dispute, the original panel added:
even by the US meat industry's calculations, only some 5% of domestic meat might
actually be commingled with imported meat. However, this evidence is silent on
whether in practice less than 5% of domestic meat ends up being commingled. It does
not specify either in what proportion such domestic meat might be commingled with

288 United States' first written submission, paras. 29-30, 115-116, and 177.
289 In the original proceedings, the United States asserted that evidence "indisputably show[ed]
significant use of the commingling provisions". The United States also alleged "occurrence of commingling on a
widespread basis". Appellate Body Reports, US – COOL, paras. 27 and 296. The complainants contended that
figures provided by the United States on Label A "are too low and that those on commingling are exaggerated".
Panel Reports, US – COOL, para. 7.370. Mexico asserted that United States did "not clearly demonstrate [the
occurrence] of commingling" and that the original "[p]anel's conclusion that the evidence did not provide
compelling proof of the occurrence or extent of commingling is, therefore, 'entirely reasonable'".
Appellate Body Reports, US – COOL, para. 298.
290 See Panel Reports, US – COOL, paras. 7.364-7.368. The Appellate Body rejected the United States'
appeal against the original panel's review of the evidence on commingling. According to the Appellate Body,
"[b]ased on the Article 11 standard articulated above, we do not believe that the Panel's determinations
regarding segregation and commingling evince a failure to assess the facts objectively." Appellate Body

imported meat, i.e. the quantities and shar e of non-US origin meat involved in any
commingling.292
7.123. In general, the complainants rely on witness statements to seek to prove that the
elimination of the commingling flexibility "ha[s] significant impact on [processors'] plants" 293 and
"almost certainly … [leads] to distinct breaks in production". 294 However, the complainants do not
submit a list of identified enterprises that co mmingle or the extent of commingling by these
entities. When asked to provide the number or share of commingling operators, Canada refers to a
potential range of commingling calculated by the USDA 295, and to cattle and hog procurement
maps that do not provide direct data on the extent of commingling. 296 Mexico has no official
statistics on commingling.297 Instead, Mexico relies on statements illustrating the refusal of certain
US producers to process imported meat 298, reduced demand for Mexican cattle 299, and other
negative effects allegedly associated with the elimination of commingling. 300 These statements do
not specify the actual use of commingling or the extent thereof.
7.124. The United States relies on the comments the USDA received on the proposed 2013 Final
Rule concerning the actual extent of commingling, according to which only three beef processors
and no pork processors confirmed that they commingled. 301 Conversely, in its comments on the
proposed 2013 Final Rule, the American Meat Institute stated that there were at least fifteen large
cattle slaughter plants and at least six hog slaughte r facilities in the United States that processed
mixed origin livestock. 302 Similarly, Mexico submits a statement of nine meat processors, "many"
of which claim having practised commingling. 303 While these statements show the existence of
commingling, they do not quantify its extent in the US market.
7.125. As regards the actual extent of commingling under the amended COOL measure,
the United States relies on estimates made by the USDA in the 2013 Final Rule, which conclude
that the extent of commingling in the US meat industry is between 5% and 20%, and that actual
commingling likely fell closer to the lower end of 5%.
304 Canada also relies on the USDA estimates
of 5% and 20%. 305 According to Mexico, the removal of commingling affected 18-21% of beef
products sold in the US.306
7.126. Based on the above, like the original panel 307, we conclude that it appears that some
commingling was taking place before the amended COOL measure both for cattle and hogs and
resulting muscle cuts, but it is difficult to establish its precise extent. In light of the parties'
arguments, we can only conclude that the use of the commingling flexibility did not exceed the
rough estimate of 20% in the livestock and meat industry. However, we are unable to establish
the share of commingling with any more specificity.

of certain cattle and hog facilities with respect to their acceptance of Category B and C cattle. However, these
data do not allow the Panel to identify the exact extent of commingling either in the mentioned facilities, or in
the US meat industry in general. In response to the Panel's request for clarification, Canada admits that the

7.127. As to the country order flexibility, the parties do not address its extent. Absent arguments
and evidence, we cannot determine its extent either. In any event, we need not do so. 308 For the
purpose of comparing the design and structure of the original and amended COOL measures,
it suffices to conclude that both the commingling and country order flexibilities were clearly
available possibilities under the original COOL me asure, and that these have now been eliminated.
Having removed these flexibilities, the amended COOL measure leads to increased segregation for
US-slaughtered livestock and resulting muscle cuts.
309
Amended coverage of Label D
7.128. The 2013 Final Rule changed the coverage of Category D. As explained 310, under the
2009 Final Rule, Category D extended to "[i]mported covered commodities for which origin has
already been established as defined by this law (e.g., born, raised, and slaughtered or produced)
and for which no production steps have occurred in the United States ".
311 The 2013 Final Rule
refers to "[m]uscle cut covered commodities derived from an animal that was slaughtered in
another country … including muscle cut covered commodities derived from an animal that was
born and/or raised in the United States and slaughtered in another country".
312
7.129. The complainants do not challenge the amended COOL measure as regards imported
muscle cuts from foreign-slaughtered livestock (Category D). As Canada explains, it "has not
challenged the WTO-consistency of Label D under the COOL measure" 313, and "does not make
claims of inconsistency of the provision of the amended COOL measure pertaining to the labelling
of muscle cuts of foreign origin imported into the United States (referred to as Label D)."
314
Likewise, "Mexico is not challenging Label D."315
7.130. For the sake of completeness and in light of the parties' arguments 316, we nonetheless
briefly review whether the amended coverage of Label D may lead to an increase in the number of
distinct labels.
7.131. The change in coverage of Label D means that, under the amended COOL measure,
Label D can cover muscle cuts from livestock of possibly four different origins depending on
whether – prior to foreign slaughter – birth and/or raising took place in the foreign country and/or
the United States, namely:
a. livestock born, raised, and slaughtered outside the United States (Scenario D1);
b. livestock born outside the United States, raised in the United States, and slaughtered
elsewhere (Scenario D2);
c. livestock born in the United States, and raised and slaughtered elsewhere (Scenario D3);
and
d. livestock born and raised in the United States, and slaughtered elsewhere (Scenario D4).
7.132. However, because Label D continues to indicate only the place of slaughter
317, this change
does not entail any increase in the number of labels, as shown in Table 12 below. Although muscle

317 Unamended, the COOL statute describes Category D muscle cuts as those "derived from an animal
that is not born, raised, or slaughtered in the United States", and requires designating "a country other than
the United States as the country of origin of such commodity." COOL statute, § 1638a(2)(D). As noted above,
the 2013 Final Rule leaves the definition of Category D muscle cuts unchanged, maintaining the direct link to

Conclusion on segregation
7.133. We have reviewed the design and structure319 of the amended COOL measure with respect
to the need for segregation. Like the original panel 320, we have concluded that for all practical
purposes, the amended COOL measure necessitates segregation of meat and livestock according
to origin.321
7.134. We have also reviewed the changes in the COOL measure's design and structure 322 to
compare the amended COOL measure's impact on segregation with that of the original COOL
measure. In light of this, we have concluded323 that:
a. point-of-production labelling in and of itself:
i. increases the need for segregating Category B muscle cuts and livestock under two
scenarios, namely muscle cuts of different single and different multiple foreign
origins;
ii. increases the need for segregating Category C muscle cuts of different multiple
foreign origins – provided that only the country of immediate import can be shown as
the country of raising on the label;
iii. does not affect the need for segregation under other scenarios of Category B and C
muscle cuts and livestock, or for Category A muscle cuts and livestock; and
b. the amended COOL measure's removal of the commingling and country order flexibilities
increases the need for segregation.

where the originating livestock was slaughtered (substantial transformation). 2009 Final Rule, § 65.300(f); and

US – COOL, para. 241.
318 This also applies to the voluntary option for Label D to show not only the country of slaughter
(substantial transformation) but also the countries of the other two production steps. Muscle cuts in Scenarios
D1 and D4 would also carry four distinct voluntary augmented Labels D. See 2013 Final Rule, § 65.300(2).

7.135. Various statements from individual industry participants 324 and groups 325 confirm that the
amended COOL measure involves increased segregation throughout both the beef and pork muscle
cuts supply chains, i.e. cattle and hogs as well as muscle cuts derived therefrom.
7.136. Accordingly, we find that the amended COOL measure involves segregation, as did its
predecessor. Indeed, as compared with the original COOL measure, for all practical purposes, the
amended COOL measure necessitates increased segregation of livestock and the resulting muscle
cuts of meat according to origin in order to meet the information requirements on origin labels.
7.137. Like the original panel, we do not consider that segregation – or increased segregation for
that matter – per se would constitute detrimental impact und er Article 2.1 of the TBT Agreement,
let alone a violation of Article 2.1. 326 We need to address whether segregation "'modifies the
conditions of competition … to the disadvantage of the imported product' by imposing higher costs
on imported than on domestic livestock." 327 Before doing so, however, we first assess the impact
of the amended COOL measure on recordkeeping, which is closely linked to the need for
segregation and its cost implications.
7.5.4.1.2.4 Recordkeeping
7.138. The parties dispute the impact of th e amended COOL measure on recordkeeping.
In particular, the complainants argue that the revised labels and elimination of commingling under
the amended COOL measure result in increased recordkeeping and verification burdens as
compared to the original COOL measure.
328 The United States counters that the 2013 Final Rule
makes no changes to the recordkeeping provisions contained in the original COOL measure, which
require accurate records irrespective of the origin of the products.
329
7.139. The provisions regarding recordkeeping an d verification are formally identical under the
original and amended COOL measures. 330 We examine whether in practice the amended COOL
measure requires greater recordkeeping as compared to the original COOL measure.
7.140. The recordkeeping requirements of the original COOL measure established an audit
verification system imposing certain recordkeeping requirements for producers along the livestock
and meat production chain.
331 In particular, the COOL statute grants authority to the Secretary of
Agriculture to "conduct an audit of any person that prepares, stores, handles, or distributes a
covered commodity for retail sale to verify compliance". 332 Persons subject to audit under this
provision must be able to make country of origin records available to the USDA for the purposes of
origin verification.
333 Further, "[a]ny person engaged in the business of supplying a covered
commodity to a retailer shall provide information to the retailer indicating the country of origin of
the covered commodity."334

324 See Exhibits CDA-25, CDA-28, CDA-29, CDA-31, CDA-32, MEX-21, MEX-22, MEX-23, and MEX-28. In
particular, for instance, Tyson, a major US processor, explains how the amended COOL measure leads to
"additional segregation at several of [its] plants and lead to significant costs not included in the [USDA's]
proposal [for the 2013 Final Rule]." Exhibits CDA-25 and MEX-21. Further, AgriBeef explains the ways in which
segregating the fabrication runs would lead to increased segregation costs. Exhibit CDA-28.

WT/DS384/RW • WT/DS386/RW

7.141. According to the 2009 Final Rule, "[a]ny person engaged in the business of supplying a
covered commodity to a retailer, whether directly or indirectly … , must maintain records to
establish and identify the immediate previous so urce (if applicable) and immediate subsequent
recipient of a covered commodity for a period of 1 year from the date of the transaction."335
7.142. As explained in the original dispute, th ese recordkeeping requirements necessarily entail
information that "can only be obtained from the upstream livestock and meat supply chain". 336
The 2009 Final Rule's explicit application to such upstream suppliers meant that:
the [original] COOL measure prescribes an unbroken chain of reliable country of origin
information with regard to every animal and muscle cut . In other words, to comply
with the COOL measure, livestock and meat processors need to possess, at each and
every stage of the supply and distribution chain, the kind of origin information
required by the various COOL labels for which each animal or portion of meat is
eligible, and they need to transmit such information to the next processing stage.
337
7.143. Under the amended COOL measure, the information that needs to be obtained and
maintained upstream continues to be closely tied to the "origin claim" that is made with respect to
a covered commodity. This is based on the unchanged requirement that "suppliers and retailers …
shall make available … records … that verify an origin claim".
338 The "origin claim"339 is therefore a
key determinant of the "records" and informatio n that are required under the amended COOL
measure for both retailers and suppliers.340
7.144. In this vein, the USDA's assertion that in practice "no additional recordkeeping is required
by [the 2013 Final Rule]" 341 is called into question by its earlier recognition that recordkeeping
burdens for various stages in the production chain are correlated to the nature of the origin claim
and the requisite accuracy of supporting inform ation. To take one example, in 2009 the USDA
"recognize[d] that animal production cycles vary greatly and depending upon which records are
used for origin verification, retention of documents should be commensurate with the claim being
affirmed through an affidavit or other means of declaration." 342 For intermediary suppliers, the

336 Panel Reports, US – COOL, para. 7.316; Appellate Body Reports, US – COOL, para. 249.
337 Panel Reports, US – COOL, para. 7.317 (emphasis added). These implications were explicitly
acknowledged in the USDA's cost-benefit analysis of the 2009 Final Rule. According to the USDA, "[t]h[e]
[2009 Final R]ule directly regulates the activities of retailers (as defined by the law) and their suppliers.
Retailers are required by the rule to provide country of origin information for the covered commodities that
they sell, and firms that supply covered commodities to these retailers must provide them with this
information. In addition, virtually all other firms in the supply chain for the covered commodities are potentially
affected by the rule because country of origin information will need to be maintained and transferred along the
entire supply chain." 2009 Final Rule, p. 2684. See also 2009 Final Rule, p. 2697 ("producers, handlers,
manufacturers, wholesalers, importers, and retailers of covered commodities" listed as part of "description of
recordkeepers"); Panel Reports, US – COOL, para. 7.318; and Appellate Body Reports, US – COOL, para. 249.
338 2009 Final Rule, § 65.500(a)(2).
339 To be precise, the "origin claim" referenced in the COOL recordkeeping requirements is initiated by
the "slaughter facility". 2009 Final Rule, § 65.500(b)(1). The USDA explains that its "authority to audit ends at
the slaughter facility as the slaughter facility is the first handler of the covered commodity" and that
"as initiators of origin claims, packers must have records to substantiate those claims". 2009 Final Rule,
p. 2674. The origin claim also serves as the basis for symmetry between the information to be provided by
retailers and transmitted by suppliers. See 2009 Final Rule, p. 2660 ("upon request by USDA representatives,
suppliers and retailers shall make available to USDA representatives, records maintained in the normal course
of business that verify an origin … claim").
340 In its Article 2.1 analysis, the Appellate Body relied upon the original panel's finding that "livestock
and meat processors need to possess, at each and every stage of the supply and distribution chain, the kind of
origin information required by the various COOL labels". Appellate Body Reports, US – COOL, paras. 339 and
342, footnote 665. In a subsequent reference to the original COOL measure's recordkeeping, the
Appellate Body mentioned labels having "less detail than the information regarding the countries in which the
livestock were born, raised, and slaughtered, which upstream producers and processors are required to be able
to identify in their records and transmit to their customers." Appellate Body Reports, US – COOL, para. 346.
We do not understand this to contradict the original panel's factual finding that recordkeeping concerned "the
kind of origin information required by the various COOL labels", as relied upon by the Appellate Body. Nor does
it disturb the reasoning set forth based on the "origin claim" under the amended COOL measure.

342 2009 Final Rule, p. 2675.
WT/DS384/RW • WT/DS386/RW

USDA anticipated that the transmission of information from "distribution centers" to retailers
"likely will require modification of existing recordkeeping processes to ensure that the information
passed from suppliers to retail stores permits accurate product labeling and permits compliance
and enforcement reviews."
343 In short, suppliers' recordkeeping burden and obligations are
explicitly tied to the "information needed to correctly label the covered commodities".344
7.145. This is consistent with the USDA's identi fication of two types of costs in relation to
recordkeeping under the original COOL measure, namely "initial costs" and "maintenance costs".345
First, "initial or start-up costs" were considered to consist of "some additional incremental costs to
record, maintain, and transfer country of origin … information to substantiate required claims
made at retail ".346 Second, "[i]n addition to these one-time costs to modify recordkeeping
systems, enterprises will incur additional recordkeeping costs associated with storing and
maintaining records". 347 For livestock in particular, it was anticipated under the original COOL
measure that "all producers of … livestock (in the case of the covered meat commodities) will
establish recordkeeping systems sufficient to substantiate country of origin claims ".
348 Further, it
was recognised that the nature of livestock production was such that both initial 349 as well as
maintenance350 costs of recordkeeping would be greater for these types of operations.
7.146. As shown above 351, an "origin claim" under the original COOL measure could consist of a
muscle cut being a "product of" the country(ies) of origin involved. In addition, the original COOL
measure stipulated that "the origin declaration [for Category B, Category C, and all commingled
muscles cuts] may include more specific information related to production steps provided records
to substantiate the claims are maintained".
352 The 2013 Final Rule now mandates such information
on all covered US-slaughtered muscle cuts, and maintains the provision for voluntary specific
information on production steps only for Category D imported muscle cuts ("provided records to
substantiate the claims are maintained").
353 This implies that the augmented origin claims with
specific information related to production steps on Labels A-C, as mandated under the amended
COOL measure, entail corresponding augmentation of the records kept by livestock and meat
producers to substantiate such claims.354

343 2009 Final Rule, p. 2685.
344 According to the 2009 Final Rule, "[t]he rule requires retailers to provide country of origin
information for all of the covered commodities that they sell. It also requires all firms that supply covered
commodities to these retailers to provide the retailers with the information needed to correctly label the
covered commodities. In addition, all other firms in the supply chain for the covered commodities are
potentially affected by the rule because country of origin information will need to be maintained and
transferred along the entire supply chain." 2009 Final Rule, p. 2693 (emphasis added).
345 See 2009 Final Rule, pp. 2697-2698, Table 9.
346 2009 Final Rule, p. 2698 (emphasis added). Further, "[e]xamples of initial or start-up costs would be
any additional or recordkeeping burden needed to record the required country of origin … information and
transfer this information to handlers, processors, wholesalers, or retailers via records used in the normal
course of business". Ibid.
347 2009 Final Rule, p. 2699.
348 2009 Final Rule, p. 2698 (emphasis added).
349 According to the 2009 Final Rule, "[i]n particular, it is believed that livestock backgrounders,
stockers, and feeders will face a greater burden in establishing recordkeeping systems. These types of
operations will need to track country of origin information for animals brought into the operation as well as for
animals sold from the operation via records used in the normal course of business, increasing the burden of
substantiating country of origin claims." 2009 Final Rule, p. 2698.
350 According to the 2009 Final Rule, "it is expected that … livestock producers will incur higher costs to
maintain country of origin … information. … [L]ivestoc k can and often do move through several geographically
dispersed operations prior to sale for processing or slaughter. Cattle, for example, typically change ownership
between 2 to 3 times before they are slaughtered and processed." 2009 Final Rule, p. 2699.
351 See Table 1 above.
352 2009 Final Rule, § 65.500(e)(4) and p. 2662 (emphasis added).
353 See 2013 Final Rule, § 65.300(f)(2) and p. 31369.
354 The USDA acknowledges that "all affected retailers and packers will have to change their labelling
practices to conform to [the 2013 Final Rule], regardless of the origin of the animal from which their muscle
cut covered commodities are derived." 2013 Final Rule, pp. 31373-31374. Further, the dynamic between
greater information on labels and more upstream records was highlighted by the USDA in its discussion of
intermediaries' obligations resulting from the 2009 Final Rule. According to the 2009 Final Rule, "[t]he
recordkeeping burden on handlers, processors, wholesalers, and retailers is expected to be more complex than
the burden most producers face. These operations will need to maintain country of origin … information on the
covered commodities purchased and subsequently furnish that information to the next participant in the supply
WT/DS384/RW • WT/DS386/RW

7.147. Further, it follows from the foregoing analysis of increased segregation under the amended
COOL measure that the revised labels create a greater variety of scenarios that must be verifiable
by retailer and supplier records. We concluded above that point-of-production in and of itself
increased the number of distinct labels for various production-step scenarios of Category B and
Category C muscle cuts.
355 Just as the creation of more labels necessitates more segregation
under the amended COOL measure, different "origin claims" require distinct substantiation for the
segregated animals and meat. This is particularly evident in the case of the removal of
commingling and country order flexibility. Tables 10 and 11 illustrate various scenarios for which,
under the original COOL measure, animals and meat with different production-step origins could
be consolidated under a unified "origin claim". Suppliers and retailers availing themselves of such a
general "origin claim" would have a recordkeeping burden and obligation commensurate with the
substantiation of that general claim. The greater diversity of labels resulting from the elimination
of commingling and country-order flexibility creates a multiplicity of scenarios for which distinct
and commensurate substantiating records are now required.
7.148. The USDA also referred to "the major cost drivers" of the 2009 Final Rule as including
inter alia "when livestock or other covered commodities are segregated in the production or
marketing process when firms are not using a multiple-origin label ".
356 As a direct result of the
2013 Final Rule, "the flexibilities afforded by the use of multiple-origin labels" 357 under the original
COOL measure are no longer available. A "mixed origin label" 358 under the amended COOL
measure must now be understood to represent a greater diversity of mutually exclusive labels
according to the possible variations of production steps.
359 Consequently, what was originally
considered a "major cost driver" is now the prec ise situation mandated by the revised labels and
removed flexibilities under the amended COOL measure.
7.149. In sum, the increase in the number of distinct labels and in segregation logically entails a
higher recordkeeping burden. Although origin claims may be substantiated by documents
maintained in the normal course of business, to the extent that origin claims become more
diverse, they entail more burdensome recordkeep ing. As products that could be covered by a
uniform origin claim are now covered by more, distinct origin claims, the one set of normal
business documentation to substantiate the previously uniform origin claim is now necessarily
replaced with distinct sets of normal business documentation to substantiate the diverse origin
claims. This logically leads to higher recordke eping burdens and costs, as also confirmed by
statements of industry participants.
360
7.150. In light of the above, we find that, compared with the original COOL measure, the
amended COOL measure entails an increased recordkeeping burden in practice for US-slaughtered
livestock and the resulting muscle cuts of meat.

chain. This will require adding additional information to a firm's bills of lading, invoices, or other records
associated with movement of covered commodities from purchase to sale." 2009 Final Rule, p. 2699.
355 See para. 7.111 above.
356 2009 Final Rule, p. 2689 (emphasis added). In this connection, we also note the USDA's
acknowledgement that "[p]rocessors handling only domestic origin products or products from a single country
of origin may have lower implementation costs compared with processors handling products from multiple
origins, although such costs would likely be mitigated in those cases where firms are only using covered
commodities which are multiple-origin labeled." 2009 Final Rule, p. 2685 (emphasis added).
357 2009 Final Rule, p. 2691.
358 See, e.g. 2013 Final Rule, p. 31374.
359 See 2013 Final Rule, p. 31377 (indicating that the amended COOL measure "no longer allows a
single mixed origin label" due to the elimination of commingling). See also Table 10 (showing one
multiple-origin label under the original COOL measure potentially spanning three distinct labels under the
amended COOL measure).

CDA-36, CDA-37, MEX-21, and MEX-26. In particular, the Food Marketing Institute explains how putting more
detailed origin information on the labels will be more costly. See Exhibits CDA-22 and MEX-26. Tyson,
AgriBeef, FPL Food, and the National Grocers' Association also elaborate on how the amended COOL measure
will increase the recordkeeping burden. See Exhibits CDA-25; CDA-28; CDA-32; MEX-21 and MEX-25,
respectively.

7.5.4.1.3 Incentives for handling domestic products and effects on the competitive
opportunities of imported products
7.151. The original panel noted that segregation "does not necessarily impose differential
implementation costs on imported and domestic products." 361 At the same time, the original panel
concluded that more segregation entails more costs:
[I]t is evident that the more origins and the more types of muscle cut labels involved,
the more intensive the need for segregation throughout the livestock and meat supply
and distribution chain. In turn, more intensive segregation leads to higher compliance
costs with the COOL measure.362
7.152. Given the Appellate Body's endorsement of this conclusion 363, w e s e e n o r e a s o n t o f i n d
otherwise in the context of these compliance proceedings.
7.153. To assess whether segregation involves differential implementation costs for imports,
the original panel compared five business scenarios based on whether the livestock being
processed has domestic or imported origin(s):
"(a) processing domestic and imported livestock and meat irrespective of origin and
solely according to price and quality;
(b) processing meat from exclusively domestic livestock;
(c) processing meat from exclusively imported livestock;
(d) processing exclusively domestic and exclusively imported livestock at different
times; or
(e) processing both domestic and imported meat by commingling the two on the
same production day."
364
7.154. The original panel concluded that "[t]he relatively less costly business scenarios are the
ones that involve processing meat from either exclusively domestic or exclusively foreign livestock
at all times" because, "as a direct result of the [original] COOL measure, business scenarios
involving more than one origin or muscle cut label result in generally higher costs than scenarios
involving only one origin."
365
7.155. In essence, this continues to apply in the context of this compliance dispute. Under the
amended COOL measure, the first four business scenarios compared by the original panel remain
valid. The fifth scenario involving commingling is no longer available. In any event, it was also
found to be more costly than single-origin scenarios.
366 As regards the relative costs of the
remaining four scenarios, various industry participants indicated that different stages of the supply
chain would move to a single-origin category approach in light of the increased costs of processing
products of multiple origin under the amended COOL measure.367

361 According to the original panel, "[t]he segregation involved in the COOL measure does not
necessarily impose differential implementation costs on imported and domestic products. If imported and
domestic livestock are being processed, in principle, these need to be equally segregated from each other
according to origin. In principle, the resulting implementation costs are the same for both imported and
domestic products." Panel Reports, US – COOL, para. 7.330.
363 See Appellate Body Reports, US – COOL, paras. 261, 287, and 345.
364 Panel Reports, US – COOL, 7.333 and 7.335-7.344.
366 The original panel found that "[c]ommingling might reduce [segregation and other compliance] costs
at specific stages, but overall it still involves higher costs than processing single origin livestock only." Panel
Reports, US – COOL, para. 7.346.
367 See Exhibits CDA-17, CDA-25, CDA-28, CDA-29, MEX-22, MEX-24, and MEX-25.
WT/DS384/RW • WT/DS386/RW

7.156. Comparing the two single-origin scenarios, the original panel concluded that "it seems
logical that the scenario of processing exclusively domestic livestock and meat is in general less
costly and more viable than processing exclusively imported livestock."
368 In particular, the original
panel considered that:
[l]ivestock imports have been and remain small compared to overall US livestock
production and demand, and US livestock demand cannot be fulfilled with exclusively
foreign livestock. And even if it could be, in light of the evidence before us, it appears
that this scenario would in all likelihood involve more than one foreign origin, and thus
in general more segregation and higher compliance costs than processing exclusively
domestic livestock, which by definition has one single origin.
369
7.157. We see no significant change in the relati ve share of US and imported livestock and meat
in the US market. The United States explains th at the market has not changed in this regard. 370
Accordingly, the original panel's logic continues to apply: processing exclusively domestic livestock
and meat remains the least costly and most viable business scenario under the amended COOL
measure. As the original panel held:
overall, the least costly way of complying with the COOL measure is to rely on
exclusively domestic livestock. Thus, in general, business scenarios involving imported
livestock, including the scenario involving exclusively imported products, are overall
more costly than the exclusively Label A approach.
371
7.158. This is confirmed by statements from US industry participants of different sizes. AB Foods,
a US packing plant processing approximately 1% of the United States' annual beef production 372
noted that the segregation costs resulting from the amended COOL measure would place his
company at a competitive disadvantage to packers in parts of the country, such as the Midwest,
where there is a more consistent supply of US cattle. 373 Likewise, Tyson, a major US processor
stated with regard to the amended COOL measure:
[e]ven if a retail customer would be willing to accept 'B' or 'C' label products, there
are not enough 'B' or 'C' livestock in any region to allow any Tyson plant (or, we
believe, any other processor) to dedicate itself to 'B' or 'C' livestock, which would be
the only way to avoid the segregation costs described above and remain viable.374
7.159. Reviewing how compliance costs are borne in the supply chain, the original panel noted
that "under the COOL measure and all other things being equal, either consumers pay more or
livestock producers receive less for the livestock they sell to processors." 375 The original panel
added that "[a]s the 2009 Final Rule … explains, at least some of the compliance costs of the
COOL measure will arise at the level of suppliers of covered commodities." The USDA estimates
that the costs of the amended COOL measure will also arise in the supply chain:
[T]he Agency agrees that there will be a dditional costs associated with th[e 2013
F]inal [R]ule, although only those muscle cut covered commodities subject to COOL
requirements will be affected by the changes in this final rule. Those costs will be
incurred by processors and retailers as they adjust to the loss of commingling
flexibility and to the new labeling requirements in this final rule.

370 According to the United States, "the market forces found to exist during the original dispute – i.e.,
the vast majority of beef sold at retail is produced from animals born, raised and slaughtered in the U.S. –
have … not changed in the interim ti me period." United States' response to Panel question No. 18 (footnote

WT/DS384/RW • WT/DS386/RW

7.160. Further, according to the original panel, "the additional costs [of the COOL measure]
cannot be fully passed on to consumers." 377 The original panel took into account "the lack of
[consumer] interest in a voluntary COOL regime" 378, as noted by the USDA at the time. 379
Referencing previous disputes380, the original panel concluded that:
the COOL measure creates an incentive for participants to process domestic rather
than imported livestock because, under the COOL measure, processing meat from
exclusively domestic livestock is less costly than other business scenarios. Passing on
these costs at least in part to imported livestock in turn creates a reduction in the
competitive opportunities of imported livestock, relative to domestic livestock.
381
7.161. This continues to apply in the context of the amended COOL measure. Although in the
2013 Final Rule the USDA does not address a voluntary COOL regime, or consumer interest in such
a regime382, the USDA explains that "the expected be nefits from implementing mandatory COOL
requirements [under the amended COOL measure] remain difficult to quantify and that the
incremental economic benefits of this final rule will be comparatively small relative to those
afforded by the current COOL requirements." 383 The USDA adds that "[t]he availability of COOL
information does not imply that there will necessarily be any change in aggregate consumer
demand or in demand for products of one origin versus others."
384
7.162. US industry participants confirm that "the costs [of the amended COOL measure] will be
staggering and impossible to pass to the customer or consumer" 385 "since there are no benefits
derived for the consumer for which the consumer will pay a premium." 386 Likewise, McVean
Trading and Investments, an investment manage ment company specializing in agricultural
products, and a trader of US cattle futures, notes that:
[t]he situation in the U.S. beef industry reflects the fact that there are a large number
of cattle producers and a very small number of packers who control a significant share
of the overall kill capacity and an increasingly concentrated retail sector for meat
products. The result is that the cattle producers are price takers largely as they have
little or no market power. … The structure of the cattle and beef industries is such that

379 Panel Reports, US – COOL, para. 7.354 (citing 2009 Final Rule, p. 2682).
382 See 2013 Final Rule, p. 31372.
383 2013 Final Rule, p. 31376. The USDA explains in the 2013 Final Rule that it could not quantify the
benefits of point-of-production labelling: "information on the production steps in each country may embody
latent (hidden or unobservable) attributes, which may be important to individual consumers and result in
additional but hard to measure benefit increases. The Agency, however, has not been able to quantify this
benefit, as singling out the value of those additional latent attributes and the resultant consumer benefit
increases would require complicated modeling techniques that none of the available studies utilized."
2013 Final Rule, p. 31377. Further, the USDA "observes that the comments it has received on the proposed
rule reinforce the Agency’s conclusion that the expected benefits from implementing the final rule’s
amendments to the existing COOL labeling requirements are difficult to quantify, as no commenters provided
quantified assessments of the benefits. Moreover, the comments received do not alter the Agency’s conclusion
that the incremental economic benefits from the labeling of production steps will be positive, but likely will be
comparatively small relative to those already afforded by the 2009 COOL final rule." 2013 Final Rule, p. 31377.
384 2013 Final Rule, p. 31376. Further, according to the USDA, "an empirical finding of no change in
demand … may … imply that the economic benefits are positive but too small to be measurable in a general-
population study." Ibid. The USDA references also a study in the context of shrimp on the USDA website, which
concludes that "price is a more important determinant of buyer behavior than COOL, a finding consistent with
various consumer surveys." Consumers Appear Indifferent to Country-of-Origin Labeling for Shrimp
<http://www.ers.usda.gov/amber-waves/2012-june/consumers-appear-indifferent.aspx>. 2013 Final Rule,
p. 31376, footnote 3. The USDA adds that "[c]omments received on the 2009 final rule and previous requests
for comments elicited no evidence of significant barriers to the provision of this information other than private
costs to firms and low expected returns. Thus, from the point of view of society, such evidence suggests that
market mechanisms could ensure that the optimal level of country of origin information would be provided to
the degree valued by consumers." 2013 Final Rule, p. 31377.

WT/DS384/RW • WT/DS386/RW

there is no likelihood that any additional costs will not be passed back upstream to
cattle producers.387
7.163. Based on the points summarized above, th e original panel "preliminarily conclude[d] that
the [original] COOL measure creates an incentive to use domestic livestock – and a disincentive to
handle imported livestock – by imposing higher segregation costs on imported livestock than on
domestic livestock. Consequently, the COOL measure affects competitive conditions in the US
market to the detriment of imported livestock."
388
7.164. As a factor confirming the incentive in favour of domestic livestock, the original panel took
into account "the relative use of the muscle cut labels under the COOL measure". 389 It found that,
"despite commingling, the use of Label A affects t h e v a s t m a j o r i t y o f m e a t l a b e l l e d u n d e r t h e
COOL requirement"390, and noted that "the complainants do not contest the US argument that the
use of category C and D labels remains 'small'."391
7.165. The parties do not submit specific data on the shares of the four muscle cut labels under
the amended COOL measure. However, the United States points out that "the market forces found
to exist during the original dispute – i.e., the vast majority of beef sold at retail is produced from
animals born, raised and slaughtered in the U.S. – have … not changed in the interim time period"
since the 2009 Final Rule. 392 Further, all parties agree that the use of Label A will remain
predominant under the amended COOL measure. 393 In fact, with the removal of the commingling
flexibility, the totality of Category A muscle cuts will need to carry a Label A.
7.166. The original panel also concluded that, due to the incentive in favour of domestic livestock,
the original COOL measure created a legal necessity of making a choice for private actors in favour
of domestic livestock 394, and thus reduced the competitive opportunities of imported livestock.
Similar to the original panel, the Appellate Body likened the COOL situation to the one in the Korea
– Various Measures on Beef dispute in this regard395:
[T]he circumstances of [the original dispute] are similar to those in Korea – Various
Measures on Beef . … The Appellate Body did not find a detrimental impact on
imported beef due only to '[t]he legal nece ssity of making a choice' that the measure
itself imposed. 396 Rather, it held that the adoption of a measure requiring such a
choice to be made had the 'direct practical effect', in that market, of denying
competitive opportunities to imports. Such an effect was not 'solely the result of
private entrepreneurs acting on their own calculations of comparative costs and
benefits', but was the result of the governmental intervention that affected the
conditions of competition for beef in Korea. … The relevant question is whether it is
the governmental measure at issue that affects the conditions under which like goods,
domestic and imported, compete in the market. While a measure may not legally
require certain treatment of imports, it may nevertheless create incentives for market
participants to behave in certain ways, an d thereby have the 'practical effect' of
treating imported products less favourably. Thus, the findings in Korea – Various
Measures on Beef are consistent with, and support the proposition that, whenever the

394 See Panel Reports, US – COOL, paras. 7.386-7.392.
395 According to the original panel, "[a]s noted above, in Korea – Various Measures on Beef, the
Appellate Body found a 'reduction of competitive opportunit[ies]' for imported products relative to domestic like
products.
"We are faced with the same situation in the current dispute. The competitive opportunities of imported
livestock are reduced as the additional costs of compliance with the COOL measure incurred when handling
imported livestock are, at least in part, passed on to suppliers of imported livestock. We referenced in this
regard direct evidence of a considerable COOL discount being applied by several major processors to imported
livestock and the absence of evidence of a similar discount being applied to domestic livestock." Panel Reports,
US – COOL, paras. 7.373-7.374 (footnotes omitted).

WT/DS384/RW • WT/DS386/RW

operation of a measure in the market creates incentives for private actors
systematically to make choices in ways that benefit domestic products to the
detriment of like imported products, then such a measure may be found to treat
imported products less favourably.
397
7.167. The same considerations continue to apply under the amended COOL measure. As
explained above 398, the amended COOL measure necessitates increased segregation and
recordkeeping in practice, and it increases the incentive in favour of domestic livestock. As a
consequence, the amended COOL measure increases the practical necessity for private actors to
choose domestic over imported livestock, and has an increased negative effect on the competitive
conditions of imported livestock in the US market.
7.168. In finding a de facto negative impact on the competitive opportunities of imported
livestock, the original panel took into account the small market share of imported products.
399
The Appellate Body upheld this, confirming that de facto detrimental impact is closely connected to
the market conditions in which a measure applies.400
7.169. As noted401, imported livestock continues to have a small share in the US market. Like the
original panel, we take this into account to find that the amended COOL measure has increased
the detrimental impact on the competitive opportunities of imported livestock in the US market.
7.170. Further, like in the original dispute
402, the detrimental impact of the amended COOL
measure is confirmed by industry statements. 403 In particular, numerous statements indicate that
the amended COOL measure results in a stronger incentive for plants, retailers, or processing
companies to refuse imported cattle and hogs or resulting muscle cuts, or that the amended COOL
measure is leading to additional refusals of imported products 404 or of imported animals of
Category B or C origin. 405 Some statements attest to increased transportation costs as a result of
fewer US processors willing to accept imported livestock. 406 According to some statements,

397 Appellate Body Reports, US – COOL, para. 288 (footnotes omitted, emphasis original). The Appellate
Body added that "while detrimental effects caused solely by the decisions of private actors cannot support a
finding of inconsistency with Article 2.1, the fact that private actors are free to make various decisions in order
to comply with a measure does not preclude a finding of inconsistency. Rather, where private actors are
induced or encouraged to take certain decisions because of the incentives created by a measure, those
decisions are not "independent" of that measure. As the Appellate Body noted, the "intervention of some
element of private choice does not relieve [a Member] of responsibility … for the resulting establishment of
competitive conditions less favourable for the imported product than for the domestic product", and thus does
not preclude a finding that the measure provides less favourable treatment." Appellate Body Reports, US –
COOL, para. 291.
398 See section 7.5.4.1.2.3 above.
399 See Panel Reports, US – COOL, paras. 7.393-7.404.
400 According to the Appellate Body, "[a] market's response to the application of a governmental
measure is always relevant to an assessment of whether the operation of that measure accords de facto less
favourable treatment to imported products. That is, if a specific technical regulation adopted by a Member
gives rise to adverse effects in the market, which disparately impact imported products, such effects will be
attributable to the technical regulation for purposes of examining less favourable treatment under Article 2.1.
We understand the Panel to have considered that, in this case, the small market share held by Canadian
and Mexican livestock imports exacerbates the effects of the COOL measure. In making its finding under
Article 2.1, the Panel acknowledged that the incentive created by the COOL measure is "partly due to the
relatively small market share of imported livestock". Such reasoning is not inconsistent with a finding that it
was the COOL measure that caused the detrimental impact. Indeed, the opportunity for a technical regulation
to discriminate may well derive from its operation within a given market that exhibits particular characteristics.
In some instances, the market share held by imported products may be one such relevant characteristic."

delivery times for imported livestock would remain reduced or be made less flexible as a result of
the amended COOL measure.407 Some statements indicate that the amended COOL measure would
lead to further worsened contractual conditions for imported cattle and hogs 408, or to a worsening
of financial conditions for suppliers of imported livestock. 409 According to some statements,
imported cattle continue to be excluded from pr emium beef programs, such as the Certified Angus
Beef program, under the amended COOL measure. 410 In addition, various statements indicate that
the decreasing number of processors accepting less imported livestock as a result of the amended
COOL measure leads to an increased COOL discount on imported cattle and hogs.411
7.171. Canada and the United States also advance specific economic arguments on the evolution
of the price basis between Canadian and US cattl e following the implementation of the original
COOL measure. In particular, the United States contests Canada's claim that the price basis
between Canadian and US fed and feeder cattle has worsened to the detriment of Canadian cattle,
with feeder cattle basis having recently increased to its widest margin.412 The United States argues
that because of seasonal fluctuation, the comparison of a pre-original COOL basis to a post-original
COOL basis should be based on the averages of two time periods of similar time spans. 413 Relying
on such an approach, the United States asserts that the price basis between Canadian and US fed
cattle has actually narrowed since the implementation of the original COOL measure.414
7.172. We note that the weekly and monthly Canadian-US fed and feeder cattle price basis
fluctuates over time based on the interaction of supply and demand, making price basis trend
forecast difficult. In particular, it is not possible to fully appreciate the implications of the volatility
of the price basis by simply lookin g at its evolution over time. Failing to consider the set of factors
underlying the evolution of the price basis could in fact lead to misleading inferences. In addition,
we agree with the United States that the comparison of the average pre-original COOL basis to the
average post-original COOL basis hinges on the be nchmark period considered, i.e. the length of
the pre-original COOL period. This applies also to the figures advanced by the United States.
For instance, the United States argues that the average Nebraska/Alberta fed cattle basis for the
period 2003 to 2009 was 17 cents per pound, while the average basis for the period 2009 to 2013
was 10 cents per pound.
415 However, if the pre-original COOL period is extended to cover 1992 to
2009416, the average fed cattle basis would be lower, contradicting the United States' argument
that the average price basis has narrowed.
7.173. Instead of relying exclusively on averages, as suggested by the United States, we also
consider the actual trend of the price basis. Based on weekly Alberta-Nebraska basis data
submitted by Canada and also relied upon by the United States 417, we observe that the linear
trend of the post-original COOL price basis is slightly negative, suggesting a slightly wider margin
trend for the October 2008 to February 2014 peri od, even though the average weekly fed steers
basis for this period is smaller in absolute value than the average basis for the May 2001 to
September 2008 period.
418 Based on monthly Nebraska-Alberta fed basis data submitted by the
United States, the positive linear trend of the post-original COOL price basis implies a wider
margin trend for the period from September 2008 to December 2013419 – as illustrated in Figure 1.

7.174. Despite the methodological uncertainties pointed out by the United States, we consider
that the data on fed cattle price basis provided by both parties
421 show a slight trend in the
widening of the price basis to the detriment of Canadian cattle for the period
September/October 2008 to December 2013/Februa ry 2014, following the implementation of the
original COOL measure. In particular, the price basis of fed cattle has increased, in absolute values
and on average, by 3% weekly for the period October 2008 to February 2014 and by 10% monthly
for the period from September 2008 to December 2013.
7.175. We reach similar conclusions when considering a polynomial trend of order 2 of the post-
original COOL price basis (Figure 2), which shows in particular that the widening trend of the fed
cattle price-basis has been more pronounced since March 2011, as Canada argues.

7.5.4.1.4 Conclusion on detrimental impact
423
7.176. In light of the above, we find that, in the context of the muscle cut labels, and in
comparison with the original COOL measure, the amended COOL measure creates an increased
incentive in favour of processing exclusively domestic livestock and an increased disincentive
against handling imported livestock. 424 Accordingly, in the context of the muscle cut labels, the
amended COOL measure entails increased detrimental impact on imported livestock.
7.5.4.1.5 Actual trade effects
7.5.4.1.5.1 Parties' arguments
7.177. Canada submitted an updated version of the econometric study prepared by
Professor Sumner in the original dispute
425 with a view to providing evidence of the actual trade
effects of the amended COOL measure. In particular, this Updated Sumner Econometric Study 426
attempts to show that the negative and signif icant impact of the original COOL measure on
Canadian livestock's price basis and import ratio 427 persisted through the end of 2013 and
beginning of 2014, and that the implementation of the amended COOL measure negatively
affected prices and shares of imported livestock.

422 Exhibit CDA-179.
423 These conclusions apply to the amended COOL measure in regard to muscle cuts from
US-slaughtered livestock (Categories A-C). As explained above, the complainants do not bring claims either in
regard to muscle cuts from foreign-slaughtered animals (Category D) or the ground meat aspect of the
amended COOL measure (Category E). See sections 7.1 and 7.4 above. See also Canada's and Mexico's
responses to Panel question No. 47.

7.178. The parties disagree on the methodology of the Updated Sumner Study and the validity of
its findings. Canada argues that the Updated Sumner Econometric Study 428 with more recent data
(December 2003/September 2005 to December 2012) confirms that from 2010 through 2012 the
original COOL measure continued to drive down the Canadian-US fed cattle price basis and imports
of Canadian cattle and hog as a share of US feed or slaughter placements.
429 Canada further
submits that the significant negative long-run impact of the original COOL measure is robust to the
separated inclusion of (i) additional variables (i.e. the difference in unemployment rate in the
United States and Canada, a dummy variable for the 2008 economic recession and the producer
price index for truck transportation)
430; (ii) using monthly rather than weekly data 431; and
(iii) extending the sample period up to November 2013/February 2014. 432 Canada further argues
that the amended COOL measure exacerbates the or iginal COOL measure's negative trade effects
on Canadian livestock in terms of price basis and import flows.433
7.179. The United States disagrees with Canada's conclusions. It considers the estimations of the
long-run impact of the original and amended COOL measures to be overstated, and to suffer from
inflated statistical significance. 434 The United States posits that there are numerous data and
methodological shortcomings, including (i) the use of weekly rather than monthly data
(i.e. inaccurate unofficial weekly cattle import data
435 and unclear construction of weekly data from
quarterly or monthly data 436); (ii) the failure to extend the sample period back to 2000 437; and
(iii) the lagging nature of the unemployment difference as a recession proxy.438
7.180. The United States adds that the econom etric model of the Updated Sumner Econometric
Study is misspecified. In particular, the study su ffers from "omitted variab le bias" by failing to
include simultaneously all the factors affecting livestock demand and supply in both Canada and
the United States, namely: (i) the 2008 economic recession dummy; (ii) the 2003-2005 US ban on
Canadian cattle due to an occurrence of BSE in the Canadian herd; (iii) transportation costs;
(iv) feed costs; and (v) Canada's cattle-slaughter capacity expansion.
439 Accordingly, the
United States contends, the estimations of the original COOL measure account not only for the
original COOL measure's own effects on the price basis or import ratio but also capture some
impacts of the missing variables on the price basis or import ratio, resulting in overestimated or
underestimated coefficients of the original and amended COOL measure.
440
7.181. In addition, the United States claims that the asymptotic standard errors of the long-run
estimated coefficients used to infer the statistical significance are artificially too low, which falsely

428 The benchmark econometric specification is a dynamic model where the dependent variable (imports
of Canadian cattle and hog as a share of US feed or slaughter placements or the price difference between
imported Canadian and US livestock) is a function of the lagged dependent variable, the difference in the
exchange rate ratio between US dollar and Canadian dollar, monthly dummies, and the impact of the original
COOL measure. The impact of the original COOL measure is characterized by a so-called dummy variable,
which takes the value of zero before the entry into force of the original COOL measure and one afterwards to
represent its implementation. In addition, the benchmark specification of the import cattle ratio and cattle price
basis include a dummy variable for the implementation of the specified risk material regulation (RSM) in
Canada and another dummy variable for the reopening of US border to Canada cattle over 30 months old
following the US ban because of Canada's Bovine Spongiform Encephalopathy (BSE) crisis. The benchmark
specification of the cattle price basis also includes a lagged exchange rate ratio. The benchmark specification of
the import hog ratio also includes a time trend variable and a dummy variable for the closing of Maple Leafs
plants in Canada. The Sumner Econometric Study in the original proceedings covered the period
December 2003/September 2005 to August 2010. See Exhibits CDA-64, CDA-79, CDA-152, CDA-174, and

inflates the level of confidence in the original COOL measure's estimated impact. 441 Referring to
another econometric study on the impact of the original COOL measure undertaken by Professor
Sumner and S. Pouliot 442, the United States suggests using a different method, known as
bootstrap procedure, to estimate consistent standards errors of the Updated Sumner Econometric
Study's parameters.443
7.182. Mexico does not submit any evidence similar to Canada's Updated Sumner Econometric
Study.
7.5.4.1.5.2 Panel's analysis
Methodology
7.183. For the reasons evoked by the original pane l, we review this evidence – even though, as
confirmed in the original dispute, there is no need to verify actual trade effects to dispose of claims
under Article 2.1 of the TBT Agreement. 444 Like the original panel, we consider that it is not our
duty to establish a unified econometric report, but rather assess, in light of the arguments raised
by the parties, the robustness of the econometric re sults to the inclusion of additional explanatory
variables and extension of the sample period.445
7.184. The objective of the Updated Sumner Econometric Study is to isolate and quantify the
effect of the original and amended COOL measures on trade quantities (import ratios) and price
basis. The use of econometrics to isolate those effects also allows for a quantification of different
factors that explain the evolution of livestock's price basis and import ratio, such as the general
economic situation, the occurrence of a specific ev ent (e.g. BSE ban), seasonal effects, changes in
transportation costs, exchange rate fluctuations , and other relevant determinants. We agree that
such factors could affect or possibly invalidate any conclusions on the estimation of the impact of
the original and amended COOL measure on the quantity and price of imported livestock.
7.185. We also consider that assessing each estimated factor in the econometric specification
hinges on the degree of confidence and reliability of such estimates, defined as the level of
statistical significance. As noted in the original dispute 446, a given variable is usually said to be
statistically significant when there is at most a 5% probability that the value of the estimated
coefficient is due to chance or random error. Put differently, there is at least a 95% probability
that the value of the coefficient variable in question is different from zero.447
7.186. The Updated Sumner Econometric Study relies on a dynamic model specification to
estimate the short- and long-run impacts of the original and amended COOL measures. The long-
run estimation of the COOL impact is a non-linear function of the short-run coefficient of the COOL
measure dummy variable and the lagged dependent variable's coefficient. It assumes that the
model is in its steady state (i.e. stable production and consumption over time). To compute the
standard errors of the long-run coefficients, the Updated Sumner Econometric Study uses a linear
approximation, known as the delta method.
448
7.187. In principle, the asymptotic standard errors that are obtained from using linear
approximations can command confidence. However, as pointed out by the United States 449,
the asymptotic standard error of a non-linear function, such as the long-run coefficients, can be
too optimistic.

standard errors (that is to say more conservative and accurate than the asymptotic ones);
however, the problem of a potentially artificially high level of confidence is less severe when the
sample size is large.
451 As the sample size considered in the Updated Sumner Econometric Study is
rather large452, this problem of a potentially artificially high level of confidence should in theory be
less severe.
7.188. The short-run COOL impacts do not suffer from this specific problem of potentially
artificially high level of confidence associated with the standard errors of a non-linear function.
Accordingly, our review of the Updated Sumner Econometric Study focuses primarily on the
estimated short-run rather than long-run COOL impacts.
Robustness of the original COOL measure's estimated impact
7.189. Based on our review of the 192 "ordinary least squares" estimations of the Updated
Sumner Econometric Study (92 estimations for cattle and 100 for hogs), we conclude that the
estimated short-run impact of the original COOL measure is robust to the inclusion of the above-
mentioned additional explanatory variables
453, the extension of the sample period up to November
2013/February 2014, and the use of monthly data. In fact, the original COOL dummy variable has
a negative and significant short-run impact at the 5% level in 153 estimations (80%) out of the
192 estimated specifications. This figure rises to 175 estimations (91%) when a 10% significance
level is considered.
454
7.190. As noted455, the United States argues that the Updated Sumner Econometric Study suffers
from omitted variable bias. We are unable to fully assess this in the absence of actual regression
results of the econometric specification modified to incorporate simultaneously the United States'
additional variables. For instance, it is impossible to assess whether the inclusion of all the
variables suggested by the United States might lead to multicollinearity
456, thus altering the
confidence interval of these variables' estimated coefficients. Further, the dynamic specification of
the Updated Sumner Economic Study's model th rough the inclusion of the lagged dependent
variable (i.e. import ratio or price basis) reduces any potential variable omission bias. The findings
of the Updated Sumner Econometric Study regardin g the original COOL measure impacts are also
in line with the above-mentioned study by Prof essor Sumner and S. Pouliot submitted by the
United States.
457 This latter study finds a significant impact of the original COOL measure through
the widening of the price bases and a decline in ra tios of Canadian imports to total domestic use
for both fed and feeder cattle for the September 2005 to December 2010 period. Even though its
model is specified differently, this study reaches the same conclusion as the Updated Sumner
Econometric Study.458
Robustness of the amended COOL measure's estimated impact
7.191. In light of our review of the Updated Sumner Econometric Study with the most recent data
up to February 2014, we conclude that the amended COOL measure's estimated impact is not
sufficiently robust. The amended COOL measure' s estimated impact in the Updated Sumner
Econometric Study is negative and significant in most regressions of the cattle price basis

451 See Hamilton, James, Time Series Analysis , (Princeton University Press, 1992); and
MacKinnon, J. G., Bootstrap Methods in Econometrics , The Economic Record, The Economic Society of
Australia, 2006, Vol. 82 (s1), pp. S2-S18, 09.
452 The sample size ranges from 251 to 530 weekly observations and from 85 to 95 monthly
observations.
453 Namely transport costs, difference in unemployment rate in the United States and Canada, and
recession dummy variables. See para. 7.178 above.
454 The fact that the level of confidence of the (negative) effect of the original COOL measure varies by
model specification is not uncommon, as long as the variable of interest remain significant in most
specifications.
455 See para. 7.180 above.
456 For a definition of multicollinearity, see Panel Reports, US – COOL, para. 7.537.
457 See Exhibit US-76.
458 Namely the study by Professor Sumner and S. Pouliot includes the following additional variables:
dummy variables for the week of Independence Day, Thanksgiving and Christmas; two week lag of the
dependent variable; price of corn in the United States; price of barley in Canada; and transportation cost and
difference in unemployment. See Exhibit US-76.
WT/DS384/RW • WT/DS386/RW

specification. However, it is not significant in most of the specifications for cattle and hogs import
ratios.
7.192. As suggested by Canada, this lack of significance is probably due to the very small number
of weekly data available in the sample with on ly 11 observations for the amended COOL measure
dummy (out of 430, 431, or 530 total observations). More data covering a longer post-amended
COOL period would be necessary to draw any reliable conclusion on the robustness of the
amended COOL measure's estimated impact in the Updated Sumner Econometric Study.
Conclusion
7.193. Accordingly, we consider that the updated Sumner Econometric Study is robust in showing
that the negative and significant impact of the original COOL measure on the price basis and
import shares of Canadian livestock persiste d through the end of 2013 and beginning of 2014.
However, the econometric evidence on the impact of the amended COOL measure on the price
basis and import ratio is limited and not robust. Consequently, although the Updated Sumner
Econometric Study provides additional useful information as regards the original COOL measure,
we cannot read it as lending econometric support to our above finding that, in the context of
muscle cuts, the amended COOL measure has increased detrimental impact on imported livestock
relative to domestic like products.
7.5.4.2 Legitimate regulatory distinctions
7.5.4.2.1 Legal test
7.194. The Appellate Body has explained that a finding of de facto detrimental impact on
competitive opportunities for imported products "is not dispositive of less favourable treatment
under Article 2.1. Instead, a panel must further analyse whether the detrimental impact on
imports stems exclusively from a legitimate regulatory distinction rather than reflecting
discrimination against the group of imported products."
459 In the original dispute, the
Appellate Body summarized the inquiry into legitimate regulatory distinctions as follows:
[S]ome technical regulations that have a de facto detrimental impact on imports may
not be inconsistent with Article 2.1 when such impact stems exclusively from a
legitimate regulatory distinction. In contrast, where a regulatory distinction is not
designed and applied in an even-handed manner—because, for example, it is designed
or applied in a manner that constitutes a means of arbitrary or unjustifiable
discrimination—that distinction cannot be considered "legitimate", and thus the
detrimental impact will reflect discrimination prohibited under Article 2.1. In assessing
even-handedness, a panel must "carefully scrutinize the particular circumstances of
the case, that is, the design, architecture, revealing structure, operation, and
application of the technical regulation at issue".

7.195. Having found de facto detrimental impact on imports from the amended COOL measure,
we proceed to examine whether such impact "stems exclusively from a legitimate regulatory
distinction". Following the Appellate Body's guidance, we first identify the relevant regulatory
distinctions drawn by the amended COOL measure461, and then proceed to assess the legitimacy of
such distinctions.462

in the ETP, on the one hand, and for tuna products containing tuna caught by other fishing methods outside
the ETP, on the other hand").
462 See also Panel Reports, EC – Seal Products, para. 7.174. Specifically, the panel in EC – Seal
Products, which was the first to examine "legitimate regulatory distinctions" under Article 2.1 following the TBT
trilogy of Appellate Body Reports, considered this element to "entail[] an analysis of two main questions: (a)
WT/DS384/RW • WT/DS386/RW

7.5.4.2.2 Relevant regulatory distinctions
7.5.4.2.2.1 Relevant distinctions under the original and amended COOL measures
7.196. In evaluating the legitimacy of regulatory distinctions under the original COOL measure,
the Appellate Body began by "identify[ing] the relevant regulatory distinction", and made two
observations in this respect. First, the Appella te Body noted that the original COOL measure
"define[d] the origin of beef and pork as a function of the countries in which certain steps of the
production process (birth, raising, and slaughter) take place" and, second, that it "require[d]
retailers of muscle cuts of beef and pork to label that meat with one of four mandatory labels".
463
On this basis, the Appellate Body "consider[ed] that it is the distinctions between the three
production steps, as well as between the four types of labels that must be affixed to muscle cuts of
beef and pork, that constitute the relevant regu latory distinctions under the [original] COOL
measure".
464
7.197. The relevant regulatory distinctions identified by the Appellate Body remain broadly intact
under the amended COOL measure. As explained above, the amended COOL measure retains the
definition of origin as a function of the countries of birth, raising, and slaughter. 465 Further,
the amended COOL measure continues to require re tailers to label muscle cuts of beef and pork
with mandatory labels based on the statutory Cate gories A, B, C, and D. The 2013 Final Rule
revises Labels A-C so that they provide explicit information on the three production steps, while
the origin indication on Label D remains the same as under the original COOL measure.466
7.198. Thus, the regulatory distinctions under the amended COOL measure are essentially the
same as those under the original COOL measure. Accordingly, we consider that the distinctions
between the three production steps as well as the mandatory labels to be affixed to muscle cuts of
beef and pork are relevant regulatory distin ctions under the amended COOL measure for the
purposes of our analysis under Article 2.1 of th e TBT Agreement. The parties do not dispute that
these are relevant regulatory distinctions under the amended COOL measure.467
7.5.4.2.2.2 Other aspects of the amended COOL measure
7.199. The parties dispute the relevance of other aspects of the amended COOL measure for the
Panel's assessment of legitimate regulatory distinctions. In particular, the United States stresses
the Appellate Body's statement that "in an analysis under Article 2.1, we only need to examine the
distinction that accounts for the detrimental impact on [imported] products as compared to
[domestic] products".
468 The United States argues from this premise that the complainants
inappropriately challenge "other regulatory distinctions that either have nothing to do with the
detrimental impact caused by the amended COOL measure or, in fact, are not regulatory
distinctions at all".
469 According to the United States, these include: (i) the exemptions and defined
scope of the amended COOL measure; (ii) Label D for muscle cuts derived from foreign-
slaughtered animals; (iii) the COOL statute's proh ibition of a trace-back system; and (iv) Label E
for ground meat products. We address each of these in turn.
Exemptions under the amended COOL measure
7.200. With regard to the relevance of the exemptions, the complainants highlight the
Appellate Body's reference in its Article 2.1 analys is to exempted products, and point out that the

first, what are the relevant regulatory distinctions under the [measure]; and (b) second, are such regulatory
distinctions 'legitimate'".

469 United States' first written submission, para. 81.
WT/DS384/RW • WT/DS386/RW

exemptions under the original COOL measure are unchanged by the 2013 Final Rule. 470
The United States counters that the exemptions are outside the Article 2.1 inquiry as they do not
cause any detrimental impact.
471 In particular, the United States cites the original panel's
statements that "[t]he exact proportion or magnitud e of the exceptions or exclusions is irrelevant
for our review of the complainants' claims under Article 2.1 of the TBT Agreement" 472, and that
"the exceptions to the coverage of the COOL me asure do not alter the distribution of compliance
costs for livestock and meat producers and processors in a way that would modify the incentives
created by the COOL measure".473 The United States thus argues that the exemptions and scope of
the amended COOL measure "cannot explain whet her the detrimental impact stems exclusively
from legitimate regulatory distinctions".474
7.201. We draw guidance from the Appellate Body 's examination of the original COOL measure,
where it "consider[ed] relevant the fact that the COOL measure exempts from its labelling
requirements muscle cuts of beef and pork that are 'ingredient[s] in a processed food item', or are
sold in a 'food service establishment' or in an establishment that is not a 'retailer'". 475 We agree
with the United States that the exemptions were no t explicitly identified by the Appellate Body as
relevant regulatory distinctions, and that they were not found by the original panel to be a source
of detrimental impact. Nevertheless, the exemptions formed a key element of the Appellate Body's
evaluation of the legitimacy of regulatory distinctions under the original COOL measure.
476
7.202. In our view, this is consistent with the Appellate Body's explanation that, having
determined the detrimental impact and relevant regulatory distinctions under Article 2.1, a panel
must "carefully scrutinize the particular circumstances of the case, that is the design, architecture,
revealing structure, operation, and application of the technical regulation at issue".
477 In the
original dispute, the three production steps and fo ur muscle cut labels were distinctions drawn by
the original COOL measure that did not operate in isolation, but were given effect in conjunction
with other elements essential to the measure's design and operation. 478 The assessment of
legitimate regulatory distinctions took account of the "overall architecture" 479 of the measure, and
encompassed aspects of the measure that were no t themselves "relevant regulatory distinctions"
or independent sources of detrimental impact.480
7.203. The requirement for a broad appraisal of a measure's design and application is also
consistent with the notion that detrimental impact forms the foundation, but not the entirety, of
the inquiry into legitimate regulatory distinctions.
481 Indeed, as the United States has emphasized,
discrimination under Article 2.1 must not be equated to detrimental impact alone. 482 Therefore,

470 See Canada's first written submission, paras. 69-71, and second written submission, paras. 28-30;
Mexico's first written submission, paras. 133-137, and second written submission, paras. 49 and 61-65.
471 See United States' first written submission, para. 87 and second written submission, paras. 60-61.

473 United States' first written submission, para. 88 (citing Panel Reports, US – COOL, para. 7.419).
474 United States' second written submission, para. 61.
475 Appellate Body Reports, US – COOL, para. 344.
476 See, e.g. Appellate Body Reports, US – COOL, para. 348 ("We emphasize that … the limited
consumer information conveyed through the retail labelling requirements and exemptions therefrom … is of
central importance to our overall analysis under Article 2.1") (emphasis added).
477 Appellate Body Reports, US – COOL, para. 271 (citing Appellate Body Report, US – Clove Cigarettes,
para. 182).
478 As explained further below, these elements included the recordkeeping of required information as
well as the exemptions from ultimately providing such information to consumers. See Appellate Body Reports,
US – COOL, paras. 342 and 344.
479 Appellate Body Reports, US – COOL, para. 346.
480 This incorporation of the exemptions into the Article 2.1 analysis is not at odds with the findings of
the original panel that the exemptions do not in themselves "alter the distribution of compliance costs for
livestock and meat producers and processors in a way that would modify the incentives created by the
COOL measure." See Panel Reports, US – COOL, para. 7.419. While they do not modify incentives to the
detriment of imported livestock, they are relevant to the distinct question of whether that detriment stems
exclusively from legitimate regulatory distinctions.
481 See, e.g. Appellate Body Reports, US – COOL, para. 327 (placing focus on whether "the detrimental
impact reflects discrimination in violation of Article 2.1") (emphasis added). See also Appellate Body
Reports, US – Tuna II (Mexico), para. 231; and US – Clove Cigarettes, para. 224; and United States' second
written submission, para. 20.
482 See, e.g. United States' second written submission, para. 10, and opening statement at the meeting
of the Panel, para. 3.
WT/DS384/RW • WT/DS386/RW

although the exemptions under the amended COOL measure are not "relevant regulatory
distinctions" as such, we nevertheless take them into account as part of our examination of the
"overall architecture" of the amended COOL measure, insofar as they are relevant to whether
"the detrimental impact reflects discrimination in violation of Article 2.1".
483
Label D
7.204. As noted, the complainants clarify that they do not challenge Label D 484, and no
detrimental impact on foreign livestock has been demonstrated to derive from Label D
requirements.485 In the original dispute, the Appellate Body explicitly identified "the distinctions
between … the four types of labels that must be affixed to muscle cuts of beef and pork" as
relevant regulatory distinctions under the original COOL measure. 486 Given the complainants'
explicit delimitation of their claims and the lack of demonstrated detrimental impact, however, the
relevance of Label D for legitimate regulatory distinctions must accordingly be adjusted in this
compliance dispute. To the extent that Label D co ncerns the "overall architecture" of the amended
COOL measure, and hence is relevant to the analysis of legitimate regulatory distinctions, we
consider it below as it relates to the relevant distinctions identified above for other muscle cut
labels.
Trace-back prohibition
7.205. It is in a similar light that the COOL statute's prohibition of trace-back could be considered
under Article 2.1. In contrast to Label D an d the exemptions, the Appellate Body made no
reference to the trace-back prohibition in its assessment of regulatory distinctions under the
original COOL measure. The complainants put forward various arguments that this aspect of the
amended COOL measure evidences a violation of Article 2.1.
487 We address these arguments
below to the extent relevant to our overall examination of legitimate regulatory distinctions.
Label E
7.206. With respect to Label E for ground meat products, we recall the finding in the original
dispute that "the complainants ha[d] not demonstrated that the ground meat label under the
COOL measure results in less favourable treatment for imported livestock."
488 We have explained
above that the complainants do not challenge the ground meat label as a distinct claim in this

483 Appellate Body Reports, US – COOL, para. 327. See also Appellate Body Report, US – Clove
Cigarettes, para. 182. While we are mindful that "under Article 2.1, we only need to examine the distinction
that accounts for the detrimental impact", we agree with Canada that this is not "intended to exclude
everything from the analysis that is extraneous to the regulatory distinction(s) that cause the detrimental
impact on imported products". See Appellate Body Report, US – Tuna II (Mexico), para. 286 (emphasis
original); and Canada's second written submission, para. 48. As Canada points out, such a narrow approach
would contradict the Appellate Body's general guidance under Article 2.1 and conflict with its analytical
approach in the original dispute. At the same time, the broad examination of the amended COOL measure
encompassing its "overall architecture" is not without limits, and consideration of other "extraneous" factors
must remain anchored in the measure's relevant regulatory distinctions and detrimental impacts. In this
connection, we note Mexico's differentiation between "detrimental impact", "relevant regulatory distinction(s)",
and "facts and circumstances related to the design and application of the relevant regulatory distinction(s)".
Mexico raises aspects of the amended COOL measure that, in its view, relate to the third of these three
concepts, but that are not themselves "regulatory distinctions". See Mexico's opening statement at the meeting
of the Panel, para. 28.
484 See Canada's and Mexico's responses to Panel question No. 47.
485 See paras. 7.128-7.132 above.

488 Panel Reports, US – COOL, para. 7.437. The Appellate Body "[did] not address the additional
category for ground meat (Category E) and the associated labelling rules since the Panel concluded that the
complainants had not established that these result in less favourable treatment for imported livestock, and no
participant appeals this finding". Appellate Body Reports, US – COOL, footnote 388.

compliance dispute.489 Rather, Canada and Mexico advance arguments that the ground meat label
evidences a lack of even-handedness or legitimacy of regulatory distinctions under Article 2.1.490
7.207. These arguments do not affect the original finding that the ground meat label had not been
shown to result in less favourable treatment for imported livestock. 491 Further, we see no reason
to depart from the Appellate Body's non-inclusio n of the ground meat label among the relevant
regulatory distinctions under the original COOL measure, or from the unappealed findings of the
original dispute with respect to the ground meat label.
492 A c c o r d i n g l y , w e f i n d t h a t t h e g r o u n d
meat label does not constitute a relevant regulatory distinction of the amended COOL measure for
the purposes of Article 2.1.
7.5.4.2.3 Appellate Body analysis of legitima te regulatory distinctions in the original
dispute
7.208. Having determined that the original panel's analysis under Article 2.1 was "incomplete" for
having concluded on a finding of detrimental impact 493, the Appellate Body reviewed a number of
the original panel's factual findings that "provided a sufficient basis for [it] to determine whether
the detrimental impact on Canadian and Mexican livestock stems exclusively from a legitimate
regulatory distinction".494 It then proceeded to "examine, based on the particular circumstances of
this case, whether these distinctions are designed and applied in an even-handed manner, or
whether they lack even-handedness, for example, because they are designed or applied in a
manner that constitutes arbitrary or unjustifiable discrimination".495
7.209. The Appellate Body "start[ed] by considering the recordkeeping and verification
requirements imposed by the COOL measure, whic h the Panel found to the be the source of the
incentive for US producers to process exclusively domestic livestock", and described the associated
burden placed on upstream livestock and meat producers.496
7.210. The Appellate Body next found that "[a]s designed and applied, however, the COOL
measure does not impose labelling requirements for meat that provide consumers with origin
information commensurate with the type of origin information that upstream livestock producers
and processors are required to maintain and transmit". 497 I n s u p p o r t o f t h i s c e n t r a l p o i n t , t h e
Appellate Body made a series of observations about the original COOL measure concerning: the

489 See section 7.4 above.
490 In particular, Canada argues that "the logic that underpinned the Appellate Body's analysis weighs in
favour of the amended COOL measure's treatment of ground meat being regarded as a relevant factor in
assessing the measure's consistency with TBT Article 2.1". Canada's second written submission, paras. 40-42;
see also Canada's first written submission, para. 81. Mexico argues that "[i]n light of the ostensible consumer
information objective of the measure, providing such flexibility for one form of beef product and not for another
form is completely arbitrary". Mexico's first written submission, para. 140. According to Mexico, "[i]t is
irrelevant that a different production method is used for the beef" as ground beef and muscle cuts are sold to
the same US consumers, and because "[t]he objective at issue does not relate to the method of processing
but, rather, to the origin content of the processed beef when viewed from the perspective of the U.S.
consumer". Mexico's second written submission, para. 70. See also para. 7.280 below.
491 Canada and Mexico's arguments focus on the flexibilities for ground meat and the accuracy of
resulting labels, but they do not address whether and how the ground meat labelling rules account for any
alleged detrimental impact on imported livestock. Indeed, the original panel reviewed in detail the features of
the ground meat labelling rules and their flexibility, before noting that Canada and Mexico "ha[d] not made
specific arguments in response to the United States' contentions regarding this flexibility, nor as to how any
remaining costs would affect imported livestock less favourably in the context of ground meat". See Panel
Reports, US – COOL, paras. 7.421-7.436.
492 The ground meat label is therefore different from the trace-back prohibition. The trace-back
prohibition was not similarly examined in the original dispute. The complainants present this as a novel
argument in this compliance dispute in light of the Appellate Body's elaboration of the Article 2.1 legal test.

494 Appellate Body Reports, US – COOL, para. 340.
495 Appellate Body Reports, US – COOL, para. 341.
496 Appellate Body Reports, US – COOL, para. 342. The Appellate Body noted in particular that livestock
and meat producers were required "to track and transmit to their downstream buyers information regarding
the countries in which each production step took place for the animals and/or meat that they process". Ibid.
497 Appellate Body Reports, US – COOL, para. 343 (original emphasis).
WT/DS384/RW • WT/DS386/RW

accuracy of labels and their omission of production step information; labelling flexibilities for
commingled meat; and the exemptions from coverage.498
7.211. The Appellate Body additionally recall ed that, under the US market's particular
circumstances, "the burden of the recordkeepin g and verification requirements, the consequent
need for segregation, and the associated comp liance costs" combined to make processing
exclusively domestic livestock "the least cost ly way of complying with the COOL measure". 499
The Appellate Body further reasoned:
Taking account of the overall architecture of the COOL measure and the way in which
it operates and is applied, we consider the detail and accuracy of the origin
information that upstream producers are required to track and transmit to be
significantly greater than the origin information that retailers of muscle cuts of beef
and pork are required to convey to their cu stomers. That is, the labels prescribed by
the COOL measure reflect origin information in significantly less detail than the
information regarding the countries in which the livestock were born, raised, and
slaughtered, which upstream producers and processors are required to be able to
identify in their records and transmit to their customers.
500
7.212. On these grounds, the Appellate Body co ncluded that "[the original COOL measure's]
recordkeeping and verification requirements impose a disproportionate burden on upstream
producers and processors, because the level of information conveyed to consumers through the
mandatory labelling requirements is far less detailed and accurate than the information required to
be tracked and transmitted by these producers and processors."
501 Thus, "the detrimental impact
caused by the same recordkeeping and verification requirements under the [original] COOL
measure cannot be explained by the need to provide information to consumers."502
7.213. Accordingly, the Appellate Body found that the detrimental impact on imported livestock
did not stem exclusively from legitimate regulatory distinctions as "the regulatory distinctions
imposed by the [original] COOL measure amount to arbitrary and unjustifiable discrimination
against imported livestock, such that they canno t be said to be applied in an even-handed
manner".503
7.5.4.2.4 Legitimate regulatory distinctions under the amended COOL measure
7.214. Based on the Appellate Body's guidance, and in light of the parties' arguments, we turn to
whether the amended COOL measure's detrimental impact "stems exclusively from … legitimate
regulatory distinction[s]".504 In doing so, we take note of the analytical framework utilized by the
EC – Seal Products panel, which was informed by the Appella te Body's approach to Article 2.1 of
the TBT Agreement in the original dispute. According to the EC – Seal Products panel, the first
element of this framework relates to whether the relevant distinctions are "rationally connected to
the objective" of the measure.505
7.215. We consider the Appellate Body's approach in the original dispute to confirm the relevance
of the challenged measure's objective to whether its detrimental impact stems exclusively from
legitimate regulatory distinctions. 506 The Appellate Body "point[ed] out, as a preliminary matter,

498 Appellate Body Reports, US – COOL, paras. 343-344.

504 Appellate Body Reports, US – COOL, para. 271. See also Appellate Body Reports, US – Clove
505 See Panel Reports, EC – Seal Products, para. 7.259. It should be noted that the panel also
considered whether there was a justification for the regulatory distinctions unrelated to the objective, and went
on to examine even-handedness based on the particular regulatory distinctions and facts of the dispute. Given
its other findings under the TBT Agreement, the Appellate Body did not specifically review the panel's analysis
of legitimate regulatory distinctions under Article 2.1.
506 See also US – Clove Cigarettes, para. 225 ("[W]e are not persuaded that the detrimental impact of
[the challenged measure] on competitive opportunities for imported [products] does stem from a legitimate
WT/DS384/RW • WT/DS386/RW

that the [original p]anel identified the objective pursued by the United States as being 'to provide
consumer information on origin'". 507 The Appellate Body also noted that the definition of origin
under the original COOL measure was a function of the three production steps (born, raised, and
slaughtered), and that the "various categories for muscle cuts of meat, and the labelling
requirements applicable to each, are particularly relevant to an inquiry as to the COOL measure's
even-handedness".508 In addition, the Appellate Body displayed a concern for "the origin
information that retailers of muscle cuts of b eef and pork are required to convey to their
customers" in its overall assessment of the regulatory distinctions under the original COOL
measure.509 This reflects the Appellate Body's understanding of the objective of the original COOL
measure as being "the provision of consumer information on origin".510
7.216. We consider that the assessment of legitima te regulatory distinctions under Article 2.1 is
different from the inquiry into the legitimacy of a technical regulation's objective, as well as from
the review of a technical regulation's contribution to that objective. Whereas the latter inquiries
form part of the necessity analysis under Article 2.2, which we discuss below, the analysis under
Article 2.1 is confined to the specific distinctions drawn by the measure in conjunction with
relevant aspects of the "the design, architecture, revealing structure, operation, and application of
the technical regulation at issue".
511 Thus, we examine the regulatory distinctions of the measure
in light of the objective the measure seeks to achieve.
7.217. As explained below, the objective of th e amended COOL measure is to provide consumer
information on origin. 512 Accordingly, taking the measure's objective as a point of reference, and
drawing upon the Appellate Body's guidance, we assess the amended COOL measure according to
the "disconnect"513 between "the detailed information required to be tracked and transmitted by
[upstream] producers" and the information "conveyed to consumers through the labels prescribed
under the [amended] COOL measure".
514
7.218. In particular, we scrutinize the two ma in types of informational "disconnect" from
"the recordkeeping and verification requirements imposed on upstream producers and processers",
as identified by the Appellate Body:
a. "the meat or meat products are exempt from the labelling requirements altogether"; and
b. "prescribed labels do not expressly identify specific production steps and, in particular
for Labels B and C, contain confusing or inaccurate information".
515
7.219. The common comparator in the two informational disconnects 516 is the recordkeeping
required of upstream producers and processors. A ccordingly, we first address the information that
must be kept upstream under the amended COOL measure. We then turn to the information
ultimately conveyed to retail consumers in the two respects outlined above to determine whether

of a legitimate objective are not automatically "legitimate" under Article 2.1. Mexico clarifies that it does not
challenge the legitimacy of the COOL objective pursued by the United States, and refers to the panel in EC –
Seal Products, which explained that "the existence of a legitimate objective will not automatically imbue the
discrimination under Article 2.1 with legitimacy; were that to be the case, one would simply need to assess
whether the detrimental impact stems from a 'legitimate' objective." See Panel Reports, EC – Seal Products,

the amended COOL measure's detrimental impact "stems exclusively from legitimate regulatory
distinctions".
7.5.4.2.4.1 Increased recordkeeping and verification
7.220. As explained above, the recordkeeping an d verification provisions of the original and
amended COOL measures are formally identical. In practice, however, the burden of complying
with these requirements is closely linked to the "origin claim" required under the 2013 Final Rule.
The amended COOL measure's revised labels result in the need for corresponding substantiation of
the information on those labels. To the extent that greater and more detailed information is given
on an "origin claim", it is incumbent upon upstream producers and processors to transmit and
maintain such augmented information. Moreover, the greater segregation compelled under the
amended COOL measure as a result of greater labe l variety means that records must differentiate
between segregated livestock and muscle cuts.
517
7.221. It follows that "the information regarding the countries in which the livestock were born,
raised, and slaughtered, which upstream producers and processors are required to be able to
identify in their records and transmit to their customers"518, is now more exacting according to the
increased diversity of origin claims. This is particularly evident in scenarios for which the original
COOL measure permitted uniform origin claims for products of diverse origin, but which now must
be differentiated by both retailers and suppliers. In such cases, substantiating documents
maintained in the normal course of business wo uld need to be similarly differentiated to
adequately verify the claimed origin, as corroborated by industry participants.
519
7.5.4.2.4.2 Products exempt from labelling requirements
7.222. The Appellate Body took note of three ex emptions for retail labelling under the original
COOL measure, namely for:
a. entities not meeting the definition of the term "retailer";
b. ingredients in "processed food items"; and
c. products served in a "food service establishment".520
7.223. The exemptions for "ingredient[s] in a processed food item" and "food service
establishments" are established by the COOL statute 521, and are unchanged under the amended
COOL measure. 522 The USDA accordingly deemed amendments relating to the coverage of
restaurants or the definition of processed foods to be "outside the scope of this rulemaking" for the
2013 Final Rule.523
7.224. The definition of the term "retailer" is provided in the COOL statute by reference to the
Perishable Agricultural Commodities Act of 1930 (PACA).524 In response to comments on amending
this definition, the USDA stated that it "does not have the authority to develop an alternative
definition … as it is not consistent with the COOL statute". 525 The 2013 Final Rule does amend the
definition, however, from a "retailer licensed under [PACA]" 526 t o " a n y p e r s o n subject to be
licensed as a retailer under [PACA]". 527 The USDA considered that "[t]his change more closely

the PACA definition of a retailer, whether or no t they actually have a PACA license, are also
covered by COOL".528
7.225. With respect to the practical implications of this change for the coverage and application of
the amended COOL measure, the United States explains:
USDA understands that no more than a de minimis number of entities operate without
a PACA license even though they meet the licensing requirements. As such, the
United States does not consider that there are any practical implications of this
change for the coverage of the amended COOL measure.529
7.226. We therefore find that in effect the amended COOL measure retains essentially the same
exemptions from coverage as existed under the original COOL measure.
7.5.4.2.4.3 Accuracy of label information
Label accuracy under the original COOL measure
7.227. As explained below530, the original and amended COOL measures share the same objective
of providing consumer information on origin. In its assessment of regulatory distinctions made in
service of that objective with respect to the original measure, the Appellate Body considered that
"the origin information that must be conveyed to consumers is less detailed, and will often be less
accurate" than the origin information maintained upstream.
531 The Appellate Body observed that
"the [original] COOL measure requires the labels to list the country or countries of origin, but does
not require the labels to mention production steps at all." 532 The Appellate Body illustrated this
point through several examples, including the following533:
a. "Label A, indicating 'Product of the USA', which the Panel found to be the only label that
provides 'meaningful information for consumers', is not required to refer explicitly to the
productions steps of birth, raising, and slaughter."
b. "If, for example, the relevant production st eps took place in more than one country, the
relevant label (B or C) will identify more than one country, but will not identify which
production step took place in which of those countries."
c. "For Category D meat, the COOL measure requ ires only that the customs designation of
origin be indicated. Given that the United States does not use the same definition of
'origin' for customs purposes as it does fo r the COOL measure, a D Label will not convey
information on the countries of birth or raising of the livestock from which the imported
meat was derived."
7.228. The 2013 Final Rule requires that Label A for "United States country of origin designation
for muscle cut covered commodities shall include all of the production steps (i.e., 'Born, Raised,
and Slaughtered in the United States')."
534 Labels B and C are similarly augmented as muscle cuts
from animals born and/or raised abroad and slaughtered in the United States "shall be labeled to
specifically identify the production steps occurring in each country (e.g., 'Born and Raised in
Country X, Slaughtered in the United States')."
535
7.229. As a result, "origin designations for muscle cut covered commodities derived from animals
slaughtered in the United States are required to specify the production steps of birth, raising, and
slaughter of the animal from which the meat is derived that took place in each country listed on

the origin designation."536 In other words, the amended COOL measure generally seeks to address
the defect of Labels A-C identified by the Appellate Body by requiring explicit indication of the
country(ies) of each production step. Label D re mains unchanged in this respect and therefore
continues to allow omission of such information on specific production steps.
537
7.230. The Appellate Body also noted that "due to the additional labelling flexibilities allowed for
commingled meat, a retail label may indicate that meat is of mixed origin when in fact it is of
exclusively US origin, or that it has three countries of origin when in fact it has only one or two."
538
The amended COOL measure's removal of commin gling effectively eliminates this scenario.
The various scenarios we reviewed in connection with detrimental impact 539 illustrate that a
product of exclusively US origin must now be labelled as such, and that consolidated labels listing
three countries of origin can no longer be carried by products having "only one or two" countries of
origin.
7.231. Therefore, the 2013 Final Rule generally addresses factors that led the Appellate Body to
find that the original COOL measure's "prescribed labels do not expressly identify specific
production steps and, in particular for Labels B and C, contain confusing or inaccurate
information".
540
Label accuracy under the amended COOL measure
7.232. The complainants submit that the amended COOL measure may still convey potentially
misleading or inaccurate information to consumers, particularly through the flexibility for multiple
countries of raising as well as through Label C rules for the country of raising.
541
Inaccuracy due to flexibility for multiple countries of raising
7.233. There is labelling flexibility with respect to the situation of multiple countries of raising.
Thus, "if animals are born and raised in another country and subsequently further raised in the
United States, only the raising that occurs in the United States needs to be declared on the
label".
542 While this was inconsequential for the labels under the original COOL measure, the
information provided on amended point-of-production labels can now vary according to the use of
this labelling flexibility.
7.234. One of the USDA's explanations for this flexibility is that "it is understood that an animal
born in another country will have been raised at least a portion of its life in that other country."
543
Indeed, this is necessarily so given that "raised" is defined by way of exclusion from the extreme
starting and end points of an animal's life, that is from birth until slaughter or, in the case of
Category C, entry into the United States for immediate slaughter. Immediately after an animal is
born, "the period of time"
544 for raising commences and continues for the remaining lifespan.
7.235. The parties contest the potential accuracy of labels under the amended COOL measure in
view of this flexibility. By definition, the raising flexibility can only be applied to Category B
animals. Such animals will have been raised in at least two countries, one of which will be the
United States. For animals born in a foreign country, two possible production-step labelling
scenarios are: (1) born in Country X – raised in Country X and the United States – slaughtered in
the United States; and (2) born in Country X – raised in Country X, Country Y, and the
United States – slaughtered in the United States. If an animal is born in the United States, another

possible production-step scenario in Category B is born in the United States – raised in the
United States and Country X – slaughtered in the United States.545
7.236. The first scenario for foreign-born animals corresponds to Scenario B1 in Table 4 as well as
to the separate columns of Scenario B2 in Table 5 above. The second scenario for foreign-born
animals corresponds to separate columns of Scen arios B3a and B3b in Table 6 above. The third
scenario for animals born and slaughtered in the United States and raised in another country will
be referred to as Scenario B4. These are reproduced below in Table 13 in simplified form using
Country X and Country Y to represent different foreign countries. Due to the multiple countries of
raising flexibility, the labels affixed to muscle cuts would not be required to declare the information
in square brackets.

7.237. Notably, the flexibility would not allow om ission of any of the countries of raising under
Scenario B4. This is because the 2013 Final Rule stipulates that the flexibility to omit such
information is not available "where by doing so the muscle cut covered commodity would be
designated as having a United States country of origin".
546 Therefore, muscle cuts from such
animals could carry the label "Born and Raised in the United States, Raised in Country X,
Slaughtered in the United States." 547 In a sense, this provision functions as a carve-out from the
flexibility in order to prevent misleading label indications of exclusively United States origin. This is
consistent with the definition of Category A under the COOL statute 548, as well as with regulatory
concerns of Label A accuracy leading to the adoption of the 2009 Final Rule.549
7.238. In any event, Scenario B4 for animals "exported twice" 550 was considered by the USDA to
be a "relatively rare situation". 551 The evidence before us does not refute this assessment. 552

545 In this final scenario, the animal would arguably be "raised" again in the United States before being
slaughtered.
546 2013 Final Rule, § 65.300(e).
547 2013 Final Rule, p. 31368. Arguably, the USDA's statement that the label "could" read this way does
not preclude that the raising in the United States could be omitted from the label. However, we do not consider
this possibility to detract from our conclusions on Scenario B4 that: the foreign country of raising would be
listed on the label; the animal's birth in the United States would imply some amount of raising there as well;
and Scenario B4 is not a common occurrence in the actual North American trade of livestock.
548 See COOL statute, § 1638a(a)(2)(A) ("A retailer … may designate the covered commodity as
exclusively having a United States country of origin only if the covered commodity is derived from an animal
that was exclusively born, raised, and slaughtered in the United States") (emphasis added).
549 The Interim Final Rule (AMS) had initially allowed use of Label B for Category A muscle cuts. The
2009 Final Rule removed this possibility due to concern that retailers and processers would predominantly
resort to Label B for ease of compliance. As explained by the USDA, "[i]t was never the intent of the Agency for
the majority of product eligible to bear a U.S. origin declaration to bear a multiple origin designation."

WT/DS384/RW • WT/DS386/RW

We therefore find that the amended COOL measure would require accurate indication of the raising
in the foreign country in such cases. At the same time, this is qualified by the remote likelihood
that such a point-of-production scenario would actually occur in any significant numbers for traded
livestock.
7.239. We turn to the accuracy of labels under Scenarios B1-B3 with similar regard for evidence
of where such animals are actually "raised" and what must be ultimately labelled according to the
terms of the amended COOL measure.
7.240. The complainants contend that, under the flexibility for multiple countries of raising,
muscle cuts of meat may be labelled as coming from an animal raised in the United States even if
that animal spends as little as 15 days in the United States prior to slaughter.
553 This is because
animals imported for immediate slaughter, which are excluded from the raising flexibility, are
subject to "consignment directly from the port of entry to a recognized slaughtering establishment
and slaughtered within 2 weeks from the date of entry ".554 The label for muscle cuts from animals
having spent time in the United States beyond this threshold, beginning with the "15 days" argued
by the complainants, could in principle omit "the raising occurring in the other country (or
countries)".555 The use of the plural "countries" in the 2013 Final Rule means that not only muscle
cuts in Scenarios B1/B2, but also in Scenario B3, can be labelled to indicate the United States as
the sole place of raising.556
7.241. The parties have submitted generally concurring evidence as to the age at which feeder
cattle are imported into the United States 557, as well as to the amount of time fed cattle typically
spend in the United States prior to slaughter. 558 For feeder cattle, Canada submits that most of its
feeder cattle exports are between 10 to 15 months old 559, and the United States reports that the

explains that "if barley is cheaper in Canada compared to the price of corn in the US, Canada has a cost of gain
advantage that, if large enough, creates an incentives to import U.S. feeder cattle." Exhibit CDA-148.
According to Canada, "[t]hese animals are then available to be exported back to the United States for
slaughter or to be processed within Canada" and "[i]t is likely that some of the muscle cuts produced from
these animals are subsequently exported to the United States." Canada's response to Panel question No. 5,
para. 6 (emphasis added). Canada cites a specific example of "value added feeder cattle … sold to feedyards in
Quebec that finished these cattle and then shipped them back to processors in the U.S." See Canada's first
written submission, footnote 223; Canada's response to Panel question No. 8, para. 9 (citing Exhibit CDA-76,
p. 2). Mexico "does not have examples or data concerning livestock born and slaughtered in the United States,
but 'raised' in another country(ies)." Mexico's response to Panel question No. 8. Thus, we have not been given
evidence to suggest that Scenario B4 has a high probability or frequency of occurrence in US livestock trade.

557 The United States explains that it "does not import feeder cattle from any countries other than
Canada and Mexico." United States' response to Panel question No. 9, para. 19. Canada's and the
United States' estimates for feeder cattle are based on data tracking the weight of animals from which average
ages have been extrapolated. See Exhibits CDA-148 and US-50.
558 For an explanation regarding the differences between fed and feeder livestock, see Panel Reports, US
– COOL, para. 7.141 (emphasis original) (footnotes omitted):
Livestock are classified as fed or feeder depending on whether they are ready for slaughter,
or are still at the backgrounding or feeding operations stage. Most of the Canadian cattle
exported to the United States are fed cattle: these usually go through the first three stages in
Canada and are only exported to the United States for immediate slaughter. A smaller but
considerable portion of Canadian cattle are feeder cattle: these are exported to the United States
directly after the backgrounding stage. Conversely, Mexico generally exports feeder cattle
immediately after the cow/calf stage to US backgrounding and feeding operations, because of a
lack of sufficient grasslands in Mexico and the general lack of well-developed feed grains and
cattle-feedlot sectors. As regards Canadian hog exports to the United States, these involve a
larger proportion of feeder than fed hogs.
559 Canada's response to Panel question No. 9, paras. 12-13. In particular, "[t]he majority of feeder
exports are >700 lbs (72% of the annual total from 2009-2013), then 440-700 lbs (28% of the annual total
from 2009-13) with less than 1% being less than 400 lbs over the last five years. The majority of Canadian
feeder exports occur in the first half of the year (the 5 year average is 63%). This would indicate that most
feeders exported to the US are calves that are backgrounded or pre-conditioned for a period of time making
them approximately 10-15 months old (based on peak calving in Canada occurring in March)."
Exhibit CDA-148.
WT/DS384/RW • WT/DS386/RW

average age of imported feeder cattle is approximately 12 months. 560 Mexico submits 561, and the
United States does not dispute 562, that the average age of Mexican feeder cattle exports ranges
from six to seven months. For fed cattle, Canada 563 states that "[m]ost Canadian exports of fed
cattle to the United States are slaughtered within 14 days of entry into the United States." 564 This
is consistent with the United States' understanding "based on its experience in the regulation of
U.S. slaughter facilities" "that cattle imported for immediate slaughter are almost always
slaughtered the day they arrive in the United States."
565
7.242. We understand from the evidence before us that the slaughter age of cattle is
approximately 22 months. 566 Relative to this slaughter age, it is clear from the evidence that
feeder cattle exported to the United States typica lly spend a substantial part of their lifespan in
their country of birth. The parties' evidence indicates that on average Canadian feeder cattle spend
between 45 and 68%, and feeder cattle from Mexico between 27 and 32%, of their raising period
outside the United States. Yet these feeder cattle, falling in Scenarios B1 and B2 above, will be
processed into muscle cuts that are eligible to be labelled "Born in Canada/Mexico, Raised and
Slaughtered in the United States". Thus, feeder ca ttle imported into the United States may spend
68% of their lifespan outside the United States
567; yet, the resulting meat products could be
labelled to indicate that the originating animals were raised only in the United States.
7.243. Under these circumstances, we are not persuaded by the United States' contention that
such a label can be regarded as " entirely accurate"568, particularly given the definition of "raised"
according to the amended COOL measure. The ration ale for permitting flexibility to designate the
United States as the sole place of raising wa s that it would "reduce the number of required
characters on the label". 569 This was considered justifiable based on the correct presumption that
raising must naturally occur at least in part in th e country of birth. This flexibility, however, takes
no account of the substantial amount of time that traded livestock typically spend outside the
United States.
7.244. Turning to the design of the amended C OOL measure, as explained above, the amended
COOL measure would similarly afford this flexibility to designate the United States as the sole
place of raising to an animal that spent as little as 15 days in the United States. Nevertheless,
it does not appear that this occurs in practice. The parties' data indicate that Category B exports to
the United States tend to be nearer to the midpoi nt of an average animal's lifespan, and livestock
within Category C are usually slaughtered well within the 14 day window mentioned above.
These averages suggest that in its application, the amended COOL measure permits labels
indicating "raised in the United States" al one for livestock that commonly spend between
approximately one third and one half of their lives elsewhere.

WT/DS384/RW • WT/DS386/RW

Label C rules for the country(ies) of raising570
7.245. Another contended aspect of label accuracy relates to whether, under the amended COOL
measure, Label C requires that only the country of immediate export be indicated as the country of
raising.
7.246. The 2013 Final Rule addresses Labels B and C under the same provision, which requires for
animals "born and/or raised in Country X and/or (as applicable) Country Y, and slaughtered in the
United States, [that] the resulting muscle cut covered commodities shall be labelled to specifically
identify the production steps occurring in each country".
571 This is cited by the United States in
conjunction with the broad definition of "raised" under the amended COOL measure as evidence of
the "permissive nature of the measure". 572 The United States thus contends that Label C would
permit indicating multiple countries of raising for Category C if this situation were to occur.573
7.247. Canada considers that the amended COOL measure requires designation only of the
country of export as the country of raising. Canada cites the focus of the provision on animals that
"undergo raising both outside and inside of the United States before slaughter in the
United States", and that the USDA's specific guidance for Label C states:
[T]he origin information for muscle cut covered commodities derived from animals
imported for immediate slaughter as defined in § 65.180 is required to include
information as to the location of the three production steps. However, the country of
raising for animals imported for immediate slaughter as defined in § 65.180 shall be
designated as the country from which they were imported (e.g., "Born and Raised in
Country X, Slaughtered in the United States").
574
7.248. As to indication on Label C of additional countries of raising other than the export country,
we note that the COOL statute provides that a "retailer of a covered commodity … derived from an
animal that is imported into the United States for immediate slaughter shall designate the origin of
such covered commodity as (i) the country from which the animal was imported ; and (ii) the
United States".
575
7.249. Taken together, the text of the relevant provisions of the amended COOL measure,
combined with the USDA's guidance, are open to the competing interpretations put forward by the
parties. We examine label accuracy under both interpretations of the requirements for Label C
under the amended COOL measure.
7.250. Table 14 below reproduces in simplified form various point-of-production labelling
combinations in Category C from scenarios outl ined above, using Country X and Country Y to
represent different foreign countries. As in Table 13, the labels affixed to muscle cuts would not
need to declare the information in square brackets.

570 See paras. 7.103-7.110 above.

7.251. Even if the amended COOL measure is understood to allow indication of multiple countries
of raising, as asserted by the United States, it remains uncontested that this would not be
mandatory.
577 It would be an accurate reflection of an animal's raising to list the additional country
in any of Scenarios C3-C6; conversely, this accuracy would be diminished by omitting the raising
that occurred outside of the country of export. In Scenario C3/C6, the omission of the raising in
Country X may have less implications for informational accuracy if, as suggested by the USDA, one
may infer that some amount of raising will naturally occur in Country X as the place of birth.
7.252. However, the particular Scenario C4/C 5 could not similarly support such an inference
because the countries of birth and export to the United States would be the same. As shown in
Table 14 above, the omitted country of raising would not be mentioned at all on the label.
Thus, the omission of raising in Country Y for Scenario C4/C5 would result in inaccurate
information about the animal's raising, as it would indicate raising as having occurred in only one
country. In any event, we observe that all of the situations in Scenarios C3-C6, including Scenario
C4/C5, appear to be unlikely in the United States' actual trade of livestock.
578
7.253. If the amended COOL measure requires designating exclusively the country of export as
the place of raising, as contended by Canada, the ev idence before us indicates that this is in fact
compatible with the most common situation for traded Category C animals. This is represented by
Scenario C1/C2 where an animal is born and raised in the same country before import into the
United States for immediate slaughter.
579 In that scenario, the label reading "Born and Raised in
Country X, Slaughtered in the United States" 580 would be generally accurate for the animals
actually traded between the complainants and the United States. However, this is not the case for
any of Scenarios C3-C6, which would lead to label inaccuracy as described above. Specifically, the
label for Scenario C3/C6 would omit raising in Country X but would still indicate that the animal
was born in that country. The label for Scenario C4/C5 would be required to omit the other country
of raising (Country Y) altogether.
7.254. In sum, the design of Label C rules under the amended COOL measure may allow – and
possibly require – omission of actual countries of raising, resulting in label inaccuracy as to an
animal's place of raising. In its actual application to traded livestock, however, Label C does not
appear likely to convey misleading informatio n about the country where animals imported for

576 As pointed out by the United States, this could also become relevant "for the other highly improbable

immediate slaughter are raised, given that these appear to be most commonly born and raised in
the country of export.
Appearance and placement of labels
7.255. Mexico takes issue with what it considers to be obscure abbreviations and lack of
specificity as to label placement. 581 According to Mexico, consumers have limited knowledge or
understanding of the COOL labels. 582 Mexico argues that in many cases the information is "hidden
or otherwise obscured". 583 In particular, Mexico questions whether consumers understand the
meaning of an abbreviated label that says "brn in Mexico, rsd and slghtrd in US" 584, or the use of
the word "harvested" on the labels instead of "slaughtered". 585 Mexico adds that COOL information
is normally printed in very small typeface on labels, and often is on the rear of the packaging. 586
Mexico, therefore, questions whether consumers even see the COOL information.587
7.256. The amended COOL measure provides for considerable discretion as to how retailers
convey country of origin information to consumers. The use of labels and stickers 588 is subject to
the USDA's directive that "the information can be clearly understood by consumers". 589 At the
same time, retail packaging submitted by the pa rties and the above examples referenced by
Mexico reflect the potentially wide discretion afforded by the amended COOL measure. 590 Some of
these examples show that, despite the retention and transmission of origin information on birth,
raising, and slaughter, the final origin declaration can be written or placed in ways that are not
equally understandable. Ultimately, we are not in a position to determine whether consumers
would clearly understand the labels in each of the examples provided. In light of the limited
available evidence of labels under the amended COOL measure, we cannot draw conclusions on
the impact of this labelling discretion on label accuracy.
591
Relative shares of the different origin categories and exemptions under the
amended COOL measure
7.257. In terms of the incremental improvement in the information conveyed to consumers under
the amended COOL measure, the relative proportion s of meat products falling into Categories A-E
and exempted from coverage are also relevant.
7.258. Data provided by the parties indicate that, of total (muscle cut and ground) beef
consumption in the United States, between 33. 3% and 42.3% is subject to the labelling
requirements of the amended COOL measure. Of total US beef consumption, between 16.3% and
24.5% are muscle cuts carrying Labels A-D, an d between 16.6% and 17.8% are ground meat

590 See Exhibits MEX-15, MEX-48, MEX-49, MEX-50, MEX-51, MEX-52, and US-28.
591 In this connection, the Panel notes that Mexico submits labels on muscle cuts from US-slaughtered
cattle that do not show origin information according to point-of-production even after the expiration of the
2013 Final Rule's six-month adjustment period in November 2013. See Exhibits MEX-48, MEX-49, MEX-57,
MEX-58 and MEX-59. This evidence of specific labels does not address the prevalence of non-compliance with
regard to muscle cuts of beef. Accordingly, the Panel cannot draw conclusions on the precise impact of
eventual non-compliance with the 2013 Final Rule on label accuracy.
WT/DS384/RW • WT/DS386/RW

carrying Label E.592 The remaining share of beef products – between 57.7% and 66.7% – falls into
one of the three exemptions and does not get labelled.593
7.259. The parties do not provide data on the sh ares of the three point-of-production labels for
Categories A-C of the amended COOL measure. Referring to the USDA's mandatory COOL retail
record reviews conducted in 2012, the United States argues that Categories A, B, and C muscle
cuts constituted approximately 99.7% of COOL labelled muscle cuts sold in the United States, with
Labels B and C accounting for 20% of meat being labelled. 594 The United States adds that
imported Canadian beef muscle cuts would consti tute approximately only 0.1% of COOL-labelled
muscle cuts sold at retail (given that Category D meat from all sources constitutes only 0.3% of
COOL labelled beef muscle cuts).
595
7.260. Beyond numeric shares, all parties agree that in relative terms most beef will continue to
be marketed with Label A. 596 In particular, Canada and Mexico project that Label A will even
increase its market share, while the United States argues that the market shares of labels will not
change under the amended COOL measure.597 The divergence of views appears with respect to the
future evolution of the distribution of labels with in the US market. Canada is of the view that the
increased segregation requirements will create incentives for producers to choose between
different categories of animal, altering the distribu tion of the various labels within the US market
and potentially reducing the use of Label C.598
7.261. With regard to pork products, Canada and the United States disagree on the extent of the
coverage and exemptions from the amended COOL measure. 599 Both Canada and the
United States agree, however, that there is virt ually no ground pork meat subject to the amended

592 See parties' responses to Panel question A. In addition, Mexico identifies alternative sources
suggesting the proportion of beef covered by the amended COOL measure to be 25%, 30%, 33%, and 35%.
See Mexico's response to Panel question A, paras. 178-192.
593 More specifically, the parties estimate that between 34% and 51% of consumed beef is sold in a food
service establishment; between 12% and 13.7% is sold by entities not meeting the definition of "retailer"; and
between 3.7% and 10% is an ingredient in a processed food item.
594 United States' first written submission, para. 31, footnote 63, and second written submission,
595 United States' second written submission, para. 58; footnote 98. Moreover, the United States
submits that imports of beef muscle cuts have declined over time as overall consumption of beef has declined,
and there is no reason to believe that Label D meat is being sold at higher percentages in 2013 than it has in
any previous year. United States' second written submission, footnote 91; Exhibit US-33.
596 See parties' responses to Panel question A(v). See also Canada's first written submission, para. 76;
United States' first written submission, paras. 70-73.
597 Before the original panel, the United States submitted that "approximately 71 percent of the beef
sold at the retail level is being labeled as Category A", and "70 percent of the pork sold at the retail level is
being labeled as Category A". Canada and Mexico contested these figures and submitted that the proportion of
meat carrying Label A was closer to 90%. See Panel Reports, US – COOL, paras. 7.369-7.370. Further, Canada
argued before the original panel that data collected during the first quarter of 2010 showed that the different
labelling categories for muscle cuts of beef were supplied in major supermarkets as follows: Label A 78.6%;
Labels A and B 6.3%; Label B 14.2%; and Labels B and C 0.9%. According to the United States, as of July
2009 the different origin declarations for muscle cuts of beef were used in the following percentages: US 71%;
US, Canada 5%; US, Mexico 0.5%; Canada, US 0.5%; US, Canada, Mexico 22%; and foreign (category D)
0.3%. See Panel Reports, US – COOL, footnote 941.
598 Canada's response to Panel question A, para. 214 (referring to Exhibit CDA-70). See also para. 7.241
above; Mexico's response to Panel question A, para. 208; United States' response to Panel question A,
para. 199.
599 See Canada's and United States' response to Panel question A. The differences stem from the
assumptions regarding the share of US pork consumption sold in retailers (35.9% for Canada and 62.2% for
the United States) and in food service establishments (64.1% for Canada and 37.8% for the United States).
The differences in terms of shares are also the result of different assumptions regarding the share of processed
food (21.31% for Canada and 66.25% for the United States) sold at retailers and food service establishments.
The main source of difference in the share of US pork consumption sold in retailers and food service
establishments stems from the inconsistency of units of measure between carcass weight and boneless retail
weight made by Canada (as pointed out by the United States). Once the consistency of units of measure is
addressed by expressing pork from food service establishments in boneless retail weight using the USDA
conversion factors for converting pork carcass weight to retail weight (78%) and for converting pork carcass
weight to boneless weight (72.9%), and keeping the calculation structure suggested by Canada unchanged,
the differences in the amounts of the various shares submitted by both parties decrease.

COOL measure. Consequently, virtually all labell ed pork products subject to the amended COOL
measure would be muscle cuts of pork falling within Categories A-D.
7.262. Based on harmonized figures submitted by the parties, 600 of total US pork consumption,
between 15.9% and 16.5% comprises pork muscle cuts that are subject to labelling requirements
under the amended COOL measure. Conversely, be tween 83.5% and 84.1% of pork products are
exempted from labelling requirements.601
7.263. As with beef products, Canada and the United States do not provide figures on the shares
of the point-of-production labels applied to muscle cuts of pork under the amended COOL
measure. At the same time, Canada and the United States agree that the majority of pork will be
marketed with Label A.602
7.5.4.2.4.4 Overall assessment of whethe r the amended COOL measure's detrimental
impact stems exclusively from legitimate regulatory distinctions
7.264. The Appellate found for the original COOL measure that:
the informational requirements imposed on upstream producers … are
disproportionate as compared to the level of information communicated to consumers
through the mandatory retail labels. That is, a large amount of information is tracked
and transmitted by upstream producers fo r purposes of providing consumers with
information on origin, but only a small amount of this information is actually
communicated to consumers in an understandable manner, if it is communicated at
all. Yet, nothing in the [original panel's] findings or on the [original panel] record
explains or supplies a rational basis for this disconnect. Therefore, we consider the
manner in which the COOL measure seeks to provide information to consumers on
origin, through the regulatory distinctions described above, to be arbitrary, and the
disproportionate burden imposed on upstream producers and processors to be
unjustifiable.
603
7.265. We identified three key determinants in the Appellate Body's reasoning for the
informational "disconnect" of the original COOL measure:
a. informational requirements imposed on upstream producers;
b. the nature and accuracy of the information conveyed on labels; and
c. the proportion of the information that is exempted from being communicated to
consumers.
7.266. Based on our foregoing analysis, we conclude that the amended COOL measure affects the
first two of these aspects, while leaving the thir d one effectively the same as under the original
COOL measure. Specifically, although the amended COOL measure increases the information
communicated to consumers through mandatory retail labels, it necessarily increases the
associated upstream informational (recordkeeping) requirements in order to do so. In addition, the
amended COOL measure maintains the same proportion of information that is not communicated
at all to consumers due to the exemptions from coverage.
7.267. Notwithstanding the parties' disagreement as to the actual proportions of labels used, the
amended COOL measure directly responds to certain deficiencies of original Labels A-C by
requiring point-of-production information. Moreov er, the removal of commingling assures greater

600 See parties' responses to Panel question A.
601 More specifically, the parties estimate that between 12.8% and 35.6% of consumed pork is sold in a
food service establishment; between 5.1% and 15.7% is sold by entities not meeting the definition of
"retailer"; and between 33.2% and 66.2% is an ingredient in a processed food item.

WT/DS384/RW • WT/DS386/RW

accuracy of labelling for multiple-origin muscle cuts, as well as for those Category A muscle cuts to
which a commingled label would have been affixed under the previous rules.604
7.268. The greatest incremental improvemen t in origin information achieved by the
2013 Final Rule is for Labels B and C, which were effectively indistinguishable under the original
COOL measure.605 The possibility for overlap between Labels B and C is generally foreclosed under
the amended COOL measure, given the typical indi cation on Label B of the United States as a
country of raising.606 Label C could bear a similar indication of US raising only hypothetically in the
case of an animal born in the United States, raised abroad, and imported back into the
United States for immediate slaughter. This appears to be uncommon in practice and, in any
event, depends on how Label C requirements are interpreted.
607
7.269. At the same time, the revised labels introduce the potential for informational inaccuracy in
respect of where animals are "raised". While "birth" and "slaughter" are relatively straightforward
and temporally discrete, the definition of "raised" as the entire intervening period between them is
potentially problematic in the context of certain requirements of the amended COOL labels.
In particular, the amended COOL measure allows labels to read "raised in the United States"
(without listing any other country) on meat from Category B feeder cattle that spend a substantial
portion of their lives either in Canada or Mexico. This is of primary importance to our assessment
as it represents potential inaccuracy in light of the average age of cattle traded between the
complainants and the United States, explained abov e. Apart from this, the design of the amended
COOL measure permits an even greater amount of raising in Canada or Mexico to be omitted from
the label, including in the most extreme case for an animal spending as little as 15 days in the
United States before slaughter. Although Label C appears to accurately reflect the place of raising
of Category C fed cattle in practice, certain ambiguities in the design of its labelling rules may also
create the potential for inaccuracy due to the possible omission of countries of raising.
608
7.270. The United States submits that Labels A-C provide the same level of accurate and
meaningful origin information for the vast majority of labelled muscle cuts 609 and that
"the amended COOL measure has increased the level of information to consumers while not
increasing the recordkeeping and verification requirements for U.S. industry."610 We have not been
persuaded by this contention in light of the potential inaccuracies on Labels B and C with respect
to the country of raising, which do not similarly arise for Label A.
7.271. Moreover, as we have explained, according to its design, operation, and application, the
amended COOL measure necessarily imposes increased recordkeeping burdens in order to secure
information of requisite verifiability on origin. We recall in this connection the Appellate Body's
consideration, based on findings of the original panel, of "the recordkeeping and verification
requirements … to be the source of the incentive for US producers to process exclusively domestic
livestock".
611 Thus, the amended COOL measure's resp onsiveness to DSB recommendations and
rulings must be assessed with regard for the new informational shortcomings on Labels B and C,
as well as the aggravated source of detrimental impact due to increased recordkeeping.
7.272. Although the amended COOL measure has an impact on two elements of the informational
"disconnect", it fails to address in any way "the fact that the [original] COOL measure exempt[ed]
from its labelling requirements muscle cuts of beef and pork that are 'ingredient[s] in a processed
food item', or are sold in a 'food service establishment' or in an establishment that is not a
'retailer'."
612 We have no evidence before us that calls into question the original panel's finding
that "the ultimate disposition of a meat product is often not known at any particular stage of the

604 As stated in paras. 7.121-7.126 above that actual extent of commingling is not known.
605 As stated by the original panel, Labels B and C could "overlap and practice … [and thus] look the
same, provided that the countries involved in the production of the Label B and C muscle cuts in question are
the same." Panel
 Reports, US – COOL, para. 7.288.
606 See Table 13 above.
607 Further, in that hypothetical case there would be no requirement to list the raising in the
United States, but merely a possibility of doing so. See para. 7.251 above.

production chain"613. Thus, due to the increased recordk eeping burden under the amended COOL
measure, even more "information regarding the origin of all livestock will have to be identified,
tracked, and transmitted through the chain of production by upstream producers in accordance
with the recordkeeping requirements … ev en though 'a considerable proportion'
614 of the beef and
pork derived from that livestock will ultimate ly be exempt from the COOL requirements and
therefore carry no COOL label at all."615
7.273. The United States defends these continued exemptions on the basis that they do not cause
detrimental impact and are themselves even-handed in their design and application.616 As we have
explained, however, the exemptions are relevant as an integral part of "the overall architecture" of
the amended COOL measure in the assessment of regulatory distinctions drawn in service of the
measure's objective. It is therefore "of central importance to our overall analysis under
Article 2.1"
617 that between 57.7% and 66.7% of beef consumed in the United States, and
between 83.5% and 84.1% of pork muscle cuts, will convey no consumer information on origin
despite imposing recordkeeping burdens upstream that detrimentally impact competitive
opportunities for foreign livestock.
7.274. The United States also discusses how "such exemptions are often included as part of the
mandatory country of origin labelling requirements imposed by Members" 618 and that "they are
important mechanisms that policy makers use to control costs of measures in pursuit of legitimate
government objectives".619 The United States cites the size of its market (including the number of
restaurants that would be impacted by removal of the exemption) and associated burdens to
explain the rationale for its exemptions.
620
7.275. The original panel acknowledged that "it is not atypical for any kind of regulation to have
exceptions in terms of the products and entities that are subject to it. Some of such exceptions
might be justifiable for practical reasons and simply facilitate the implementation of the measure
at issue without necessarily involving protectionist intent." 621 Further, the Appellate Body has
stated that "[n]othing in Article 2.1 prevents a Member from seeking to minimize the potential
costs arising from technical regulations, provided that the technical regulation at issue does not
overtly or covertly discriminate against imports."
622 Although the Appellate Body has thus
recognized that cost considerations are not per se prohibited, it did not accept them as
supervening justification for discriminatory measures.
7.276. In light of the Appellate Body's approa ch, we do not consider that such practical
considerations justify the discriminatory nature of the amended COOL measure or call into
question the Appellate Body's concern with the exemptions in the original dispute.
7.277. In line with the Appellate Body's guidance , we consider the exemptions from the amended
COOL measure's coverage as evidence that th e recordkeeping burden giving rise to the
detrimental impact "cannot be explained by th e need to convey to consumers information
regarding the countries where livestock were born, raised, and slaughtered".623
7.278. We turn now to other factors that may pertain to the amended COOL measure's "design,
architecture, revealing structure, operation, and ap plication" in the context of Article 2.1 of the
TBT Agreement. We look in particular to the sign ificance of such aspects for whether the measure

"is designed or applied in a manner that constitutes a means of arbitrary or unjustifiable
discrimination".624
7.279. As noted, although the complainants do not challenge Label D as such 625, they contend
that it weighs against the "even-handedness" of the amended COOL measure. In the original
dispute, the Appellate Body noted that Label D w ill not convey information on the place of an
animal's birth or raising. 626 This aspect has not been modified under the amended COOL
measure.627 The complainants claim there is potential to mislead consumers given that birth or
raising in other countries may be omitted from the label. 628 As the United States points out,
however, the complainants have not provided evidence of Category D animals that were not born
and raised in the country in which they were slaughtered.
629 In other words, there is nothing
before us to suggest that muscle cuts with Label D stating "Product of Country X" will not be from
animals that are entirely a product of that country. Thus, although the omission of production
steps would result in provision of less detailed information, this does not seem apt to mislead
consumers of Category D muscle cuts in the same fashion as would omission of countries on
Labels B and C. Combined with the relatively small portion of Category D muscle cuts in the US
market, and the absence of a claim that Label D creates any detrimental impact, we are not
convinced that Label D rules of substantial transfor mation are compelling evidence of arbitrary or
unjustifiable discrimination.
7.280. With respect to Label E for ground meat products, we recall that the complainants had not
demonstrated detrimental impact caused by the ground meat rules in the original dispute.
630
The complainants refer to the large percentage of meat under the amended COOL measure that
would carry Label E, which omits point-of-production labelling and contains "significant flexibility"
as to which countries may be listed. 631 However, the original panel's findings on the ground meat
labelling rules were not appealed, nor reviewed in the Appellate Body's Article 2.1 analysis in the
original dispute. Further, it is not clear that the treatment of ground meat is sufficiently connected
to the relevant regulatory distinctions to justify incorporation into our broad 632 assessment of the
amended COOL measure's design and operation. As explained by the USDA, the production of
ground meat entails the processing of "trimmings" of diverse origin that are ground into a final
product633, and the ground meat labelling rules were adapted to the purchasing, inventory, and
production practices of US beef grinders. 634 The complainants do not refute the different forms of
processing undergone by muscle cuts and ground meat, nor do they submit arguments in this
compliance dispute as to the upstream burdens relating to ground meat. Given the findings in the
original dispute and the complainants' arguments and claims in this compliance dispute, we do not
consider Label E to evidence the amended COOL measure's violation of Article 2.1.
635
7.281. Finally, although the complainants seek to use the trace-back prohibition as evidence of
arbitrariness636, the complainants do not provide specific arguments or evidence in this context as
to the nature of the prohibited trace-back measure. Instead, the relevance of this argument to the

WT/DS384/RW • WT/DS386/RW

Article 2.1 analysis appears to be limited to whether the trace-back prohibition necessitates the
same (or similar) audit and verification system of the amended COOL measure and its related
detrimental impacts. Inasmuch as this argument reverts focus to the claimed deficiencies of the
amended COOL measure's labelling rules, we consider that this is already addressed in the
foregoing analysis.
7.282. In the original dispute, the Appellate Body found that "the manner in which the [original]
COOL measure seeks to provide information to consumers on origin, through the regulatory
distinctions described above, to be arbitrary, and the disproportionate burden imposed on
upstream producers and processors to be unjustifiable."
637 We consider that this finding is also
relevant for the amended COOL measure, which en tails an increased recordkeeping burden and a
potential for label inaccuracy, and continues to exempt a large proportion of muscle cuts.
7.283. We therefore find that, under the particul ar circumstances of this case, the detrimental
impact caused by the amended COOL measure does not stem exclusively from legitimate
regulatory distinctions.
7.5.4.3 Conclusion on less favourable treatment638
7.284. We have found that the amended COOL measure has increased the original COOL
measure's detrimental impact on the competitive opportunities of imported livestock, and that this
impact does not stem exclusively from legitimate regulatory distinctions. We therefore find that
the amended COOL measure accords less favourable treatment to imported livestock than to like
products of US origin.
7.5.5 Conclusion on Article 2.1 of the TBT Agreement
7.285. Having determined that the amended COOL measure is a technical regulation that accords
less favourable treatment to imported livestock vis-à-vis like domestic products, we find that the
amended COOL measure violates Article 2.1 of th e TBT Agreement in respect of muscle cuts from
US-slaughtered livestock (Categories A-C).
7.6 Article 2.2 of the TBT Agreement
7.6.1 Legal test
7.6.1.1 Main factors
7.286. Article 2.2 of the TBT Agreement provides:
Members shall ensure that technical regulations are not prepared, adopted or applied
with a view to or with the effect of creating unnecessary obstacles to international
trade. For this purpose, technical regulation s shall not be more trade-restrictive than
necessary to fulfil a legitimate objective, taking account of the risks non-fulfilment
would create. Such legitimate objectives are, inter alia: national security
requirements; the prevention of deceptive pr actices; protection of human health or
safety, animal or plant life or health, or the environment. In assessing such risks,
relevant elements of consideration are, inter alia: available scientific and technical
information, related processing technology or intended end-uses of products.
7.287. As regards the legal test under the first two sentences of Article 2.2, the Appellate Body
stated that "an assessment of whether a technical regulation is 'more trade-restrictive than

638 These conclusions apply to the amended COOL measure in regard to muscle cuts from
US-slaughtered livestock (Categories A-C). As explained above, the complainants do not bring claims either in
regard to muscle cuts from foreign-slaughtered animals (Category D) or the ground meat aspect of the
amended COOL measure (Category E). See sections 7.1 and 7.4 above. See also Canada's and Mexico's
responses to Panel question No. 47.

necessary' within the meaning of Article 2.2 of the TBT Agreement involves an evaluation of a
number of factors."639 In particular:
[a] panel should begin by considering factors that include: (i) the degree of
contribution made by the measure to the legitimate objective at issue; (ii) the
trade-restrictiveness of the measure; and (iii) the nature of the risks at issue and the
gravity of consequences that would arise from non-fulfilment of the objective(s)
pursued by the Member through the measure.
640
7.288. The parties agree on the relevance of these three factors. 641 Additionally, according to
Mexico, they constitute the first step under a "two-step" Article 2.2 analysis. 642 Mexico submits
that, in addition to the above three factors, this first step also encompasses "the 'relative
importance' of the interests or values furthered by the Amended COOL Measure".
643 For Mexico,
this additional factor should be the starting po int of the necessity test under Article 2.2 of the
TBT Agreement.644
7.289. According to the Appellate Body, in addition to the above three factors, "in most cases" an
Article 2.2 analysis needs to also entail a comparison of the challenged measure with possible
alternatives:
In most cases, a comparison of the challenged measure and possible alternative
measures should be undertaken. In particular, it may be relevant for the purpose of
this comparison to consider whether the proposed alternative is less trade restrictive,
whether it would make an equivalent contribution to the relevant legitimate objective,
taking account of the risks non-fulfilment would create, and whether it is reasonably
available.
645
7.290. Mexico argues that such a comparison with alternative measures is only the second step of
the Article 2.2 analysis; it is necessary only if the review of the amended COOL measure under the
first step would not lead to a finding of inconsistency.646
7.291. In light of the above, we first address whether the legal test under Article 2.2 of the
TBT Agreement entails the two-step approach advanced by Mexico. We then turn to Mexico's
suggestion that the relative importance of the in terests or values furthered by the challenged
measure constitutes an additional factor under the Article 2.2 test.
7.6.1.2 Whether Article 2.2 entails the two-step approach advanced by Mexico
7.292. Mexico relies upon647 the Appellate Body's summary of the Article 2.2 legal test:
[A]n assessment of whether a technical regulation is "more trade-restrictive than
necessary" within the meaning of Article 2.2 of the TBT Agreement involves an
evaluation of a number of factors. A panel should begin by considering factors that
include: (i) the degree of contribution made by the measure to the legitimate
objective at issue; (ii) the trade-restrictiveness of the measure; and (iii) the nature of

643 Mexico argues that "[u]nder the first step of the necessity test, the following factors are relevant to
the weighing and balancing analysis in respect of the Amended COOL Measure: (i) the "relative importance" of
the interests or values furthered by the Amended COOL Measure; (ii) the degree of contribution made by the
Amended COOL Measure to the legitimate objective at issue; (iii) the trade-restrictiveness of the Amended
COOL Measure; and (iv) the nature of the risks at issue and the gravity of consequences that would arise from
non-fulfilment of the objective(s) pursued by the United States through the Amended COOL Measure." Mexico's

the risks at issue and the gravity of consequences that would arise from non-fulfilment
of the objective(s) pursued by the Member through the measure. In most cases, a
comparison of the challenged measure and possible alternative measures should be
undertaken. In particular, it may be relevant for the purpose of this comparison to
consider whether the proposed alternative is less trade restrictive, whether it would
make an equivalent contribution to the relevant legitimate objective, taking account of
the risks non-fulfilment would create, and whether it is reasonably available.
648
7.293. According to Mexico, this approach dictates a "two-step necessity test". 649 The first step is
a "relational analysis"650 involving a "weighing and balancing" of the factors listed in the first part
of the Appellate Body's above approach in considering the measure under review. 651 The second
step is a "comparative analysis"652, which involves a "weighing and balancing" of the factors listed
in the second part of the Appellate Body's above approach in order to compare the amended COOL
measure with each reasonably available altern ative measure put forward by the complainants. 653
Mexico notes that, according to the Appellate Body, in some situations the second,
"comparative analysis" will not be necessary654:
We can identify at least two instances where a comparison of the challenged measure
and possible alternative measures may not be required. For example, it would seem to
us that if a measure is not trade restrictive, then it may not be inconsistent with
Article 2.2. Conversely, if a measure is trade restrictive and makes no contribution to
the achievement of the legitimate objective, then it may be inconsistent with
Article 2.2.
655
7.294. Relying on the phrase "at least two in stances", Mexico contends that the amended
COOL measure represents a further instance where inconsistency with Article 2.2 can be
determined by a mere "relational analysis".
656 Mexico invites the Panel to do that, and to move on
to addressing alternatives only if the first step would not lead to a finding of inconsistency.657
7.295. The United States disagrees.658 According to the United States, "[t]he comparison between
the challenged measure and an alternative measure is … central to the [Article 2.2] analysis." 659
As the Appellate Body held in the original dispute:
to demonstrate that a technical regulation is inconsistent with Article 2.2, the
complainant must make a prima facie case by presenting evidence and arguments
sufficient to establish that the challenged measure is more trade restrictive than
necessary to achieve the contribution it makes to the legitimate objective, taking
account of the risks non-fulfilment would create. A complainant may, and in most
cases will, also seek to identify a possible alternative measure that is less trade

658 This disagreement between Mexico and the United States dates back to the original dispute. Before
the Appellate Body, Mexico argued that: "[t]he concept of necessity is used in both the first and second
sentences and must be given meaning in both sentences, that is, in the context of the creation of an obstacle
to trade and in the context of a less trade-restrictive alternative. Thus, whether the technical regulation at
issue is more trade restrictive than necessary is a 'two-step' analysis. Mexico considers this approach to be in
line with the Appellate Body's clarification in US – Gambling and in Brazil – Retreaded Tyres that weighing and
balancing involves two steps: first, a preliminary analysis of the necessity of the challenged measure on the
basis of all relevant factors and, second, the conclusion of the preliminary analysis must be confirmed by
comparing the measure with possible alternatives." Appellate Body Reports, US – COOL, para. 108.
659 United States' first written submission, para. 146 (citing Appellate Body Report, Australia – Apples,

WT/DS384/RW • WT/DS386/RW

restrictive, makes an equivalent contribution to the relevant objective, and is
reasonably available.660
7.296. In this compliance dispute, neither Mexico, nor the United States, question that the
"relational analysis" of the contested measure precedes the "comparative analysis" of the
contested measure and suggested alternatives. What Mexico and the United States disagree on is
whether the "relational analysis" might be sufficient for determining that the amended COOL
measure is inconsistent with Article 2.2.
7.297. As Mexico points out, the Appellate Body foresaw this possibility in "at least two
instances".
661 In US – Tuna II (Mexico), the Appellate Body identified the above two scenarios in a
footnote to a statement foreseeing the need for the comparative analysis "in most cases".662 In the
original US – COOL dispute, the Appellate Body confirmed both exceptions 663 as well as the need
for a comparative analysis "in most cases".664
7.298. Our reading of the relevant Appellate Body statements suggests that a "comparative
analysis" would be redundant only in exceptional circumstances where consistency or
inconsistency with Article 2.2 may be deduced by looking solely at certain aspects of the
challenged measure. Mexico has not explained why the Panel is faced with such exceptional
circumstances in this case. In particular, Mexico does not argue that the amended COOL measure
falls into either of the two exceptional scenarios identified by the Appellate Body; rather, Mexico
contends that amended COOL measure represents a third scenario under which it should be found
inconsistent without looking at alternatives. However, Mexico fails to identify what this third
exceptional scenario entails in the context of the amended COOL measure.
7.299. In the original dispute, the United States challenged the original panel's "two-stage test
that involved an initial inquiry into whether the measure fulfils the objective, and only if so, a
separate and subsequent examination of whethe r the measure is more trade restrictive than
necessary based on the existence of a reasonably available less trade-restrictive alternative
measure".
665 The Appellate Body "agree[d] with the United States that" "the Panel erred"
"by finding the COOL measure to be inconsistent with Article 2.2 of the TBT Agreement without
examining the proposed alternative measures."666
7.300. The Appellate Body took issue with the or iginal panel stopping short of the "comparative
analysis".667 The Appellate Body "consider[ed] the present case to be one that calls for an
examination of the factors identified above for both the COOL measure and the alternatives
proposed by the complainants in order to determine whether the COOL measure is more trade
restrictive than 'necessary' to fulfil its objective."668
7.301. The Appellate Body did not draw any conclusions on Article 2.2 consistency at the end of
its "relational analysis". The Appellate Body called this a "preliminary assessment" of the original
COOL measure, and "proceed[ed] to examine the alternative measures proposed by
[the complainants] … to complete [its] assessment of whether the COOL measure was 'more
trade-restrictive than necessary to fulfil a legitimate objective'."

7.302. The Appellate Body undertook the "comparative analysis" before trying to draw "overall"
conclusions with regard to Article 2.2. 670 The EC – Seal Products panel adopted a similar
approach671, noting that "[t]he Appellate Body stated that all these factors [including a comparison
with alternative measures] provide the basis for th e determination of what is to be considered
'necessary' in the sense of Article 2.2 … in a particular case." 672
7.303. We do the same, and draw conclusions as to the consistency of the amended COOL
measure with Article 2.2 of the TBT Agreement only after having considered all relevant factors.
Like the Appellate Body in both US – Tuna II (Mexico)673 and the original US – COOL dispute674, we
address the following six factors before reaching an overall conclusion on the complainants'
Article 2.2 claims:
a. the amended COOL measure's degree of contribution to a legitimate objective;
b. the trade-restrictiveness of the amended COOL measure;
c. the nature of the risks at issue and the grav ity of consequences that would arise from
non-fulfilment of the objective pursued by the United States through the amended COOL
measure;
d. whether the alternatives proposed by the complainants are less trade restrictive than the
amended COOL measure;
e. whether the proposed alternatives would make an equivalent contribution to the relevant
legitimate objective, taking account of the risks non-fulfilment would create; and
f. whether the proposed alternatives are reasonably available.
7.6.1.3 Relative importance of interests or values furthered by the measure as an
additional factor
7.304. According to Mexico, the "relative importance" of the interests or values furthered by the
challenged measure is the first factor that a WTO adjudicator should assess when reviewing
necessity under Article 2.2 of the TBT Agreement. Me xico contends that, "similar to the 'necessity'
analysis in Article XX of the GATT 1994 and Articl e XIV of the GATS", "[t]he process [of assessing
'necessity' under Article 2.2] begins with an assessment of the 'relative importance' of the
common interests or values furthered by the challenged measure"
675; "after that a panel should
consider other relevant factors of the measure at issue, including the contribution of the measure
to the realization of the ends pursued by it and the trade restrictive impact of the measure, and
undertake a weighing and balancing process."
676
7.305. Mexico recognizes that "the relative importance of the common interests or values
furthered by the challenged measure" "has not been explicitly identified [as a factor] in the context
of the necessity test under Article 2.2." 677 According to Mexico, "however, in referring to the
factors to be considered under Article 2.2, the A ppellate Body referred to 'factors that include',
indicating that the referenced factors are not exhaustive."678

"risks non-fulfilment would create". See para. 7.378 below.

678 Mexico's first written submission, para. 157.
WT/DS384/RW • WT/DS386/RW

7.306. Turning to the amended COOL measure, Mexico contends that "[t]he relative importance
of the provision of consumer information is substantially lower than: protecting the environment or
protecting human beings from health risks, both of which are vital and important in the highest
degree; and protecting public morals, which a panel observed ranks among the most important
values or interests pursued by Members as a matter of public policy."
679
Accordingly, Mexico argues, "the interests and values furthered by the Amended COOL Measure
fall on the low end of the spectrum of importance."680
7.307. The United States counters that Mexico's approach is "faulty". The United States notes that
"[t]his factor does not appear in the text [of Article 2.2], and Mexico explicitly concedes that such
a factor is not part of the Appellate Body's Article 2.2 analysis in either US – COOL or in US – Tuna
II (Mexico) ."
681 The United States contrasts "Mexico's argu[ment before the Appellate Body]
that the 'importance' of the measure should be analyzed for an Article 2.2 claim" with the
"Appellate Body explaining Mexico's burden of pr oof for Article 2.2" without making any reference
to such factor.682
7.308. In US – Tuna II (Mexico) , the Appellate Body referenced the "weighing and balancing"
under the necessity test of Article XX of the GATT 1994 683 in providing guidance on the factors
involved in a necessity analysis under the first two sentences of Article 2.2. The Appellate Body did
not identify the relative importance of the values pursued by the contested measure as a relevant
factor for assessing necessity under Article 2.2.684 In US – COOL, the Appellate Body took a similar
approach685 – despite Canada's argument that, like in the context of Article XX of the GATT 1994,
"a measure will be easier to justify [under Article 2.2] if it pursues an objective that is 'vital' or
'important'."686 In neither dispute did the Appellate Body identify "relative importance" as a factor
when setting out the overall test under Article 2.2.687
7.309. The Appellate Body did confirm the relevance of Article XX for interpreting the
TBT Agreement688, and referenced some potential similarities between the necessity tests under
Article XX of the GATT 1994 and Article 2.2 of the TBT Agreement. 689 In this compliance dispute,
Mexico itself argues that there is a distinct ion between the TBT Agreement, on the one hand,
and the GATT 1994 and the GATS, on the other. 690 In describing the differences between the

684 The Appellate Body held that "[b]oth the first and second sentence of Article 2.2 refer to the notion
of 'necessity'. These sentences are linked by the terms '[f]or this purpose', which suggests that the second
sentence qualifies the terms of the first sentence and elaborates on the scope and meaning of the obligation
contained in that sentence. The Appellate Body has previously noted that the word 'necessary' refers to a
range of degrees of necessity, depending on the connection in which it is used. In the context of Article 2.2,
the assessment of 'necessity' involves a relational analysis of the trade-restrictiveness of the technical
regulation, the degree of contribution that it makes to the achievement of a legitimate objective, and the risks
non-fulfilment would create. We consider, therefore, that all these factors provide the basis for the
determination of what is to be considered 'necessary' in the sense of Article 2.2 in a particular case."

measure at issue." Appellate Body Reports, US – COOL, para. 375. See also Appellate Body Report, US –
Tuna II (Mexico), para. 319.
690 According to Mexico, "[a]lthough the necessity test in Article 2.2 is similar to the necessity tests in
Articles XX of the GATT 1994 and XIV of the GATS, it is not identical. The necessity test in Article 2.2 refers to
the necessity of the trade-restrictiveness of the measure whereas the necessity tests in the other two
WT/DS384/RW • WT/DS386/RW

relevant necessity tests, Mexico explains that "[i]mportantly, Article 2.2 includes the phrase
'taking account of the risks non-fulfilment would create'." 691 According to Mexico, "[t]his treaty
language does not exist in [Articles XX of th e GATT 1994 and XIV of the GATS] and meaning must
be given to this difference."692
7.310. "The risks non-fulfilment would create" was identified by the Appellate Body as a "further"
factor to be assessed in the context of Article 2.2.693 As Mexico points out, "the risks non-fulfilment
would create" is unique to the text of Article 2.2 of the TBT Agreement, does not appear in
Article XX of the GATT 1994 and Article XIV of the GATS. We agree that meaning must be given to
this difference.694 In our view, the most appropriate way to give meaning to this difference is to
address the risk non-fulfilment of the objective wo uld create in the context of Article 2.2, which
has been specifically identified by the Appellate Body as a factor of the Article 2.2 legal test.
We shall do this, rather than assess as a separate factor "relative importance of the objective",
which does not appear in the text of Article 2.2, and was developed only in the context of
Article XX of the GATT 1994 and Article XIV of the GATS.
7.311. Accordingly, we dismiss Mexico's contention that relative importance of the common
interests or values furthered by the challenged measure is a separate factor of the Article 2.2 test,
let alone the starting point of an Article 2.2 analysis. Instead, we review the complainants'
Article 2.2 claims by analysing the factors set out in the Appellate Body's relevant statements,
which we have listed above, including the risks non-fulfilment of the objective would create.
695
7.6.2 The amended COOL measure's degree of contribution to a legitimate objective
7.312. As the Appellate Body held, "the question of whether a technical regulation 'fulfils' an
objective is concerned with the degree of contribution that the technical regulation makes toward
the achievement of the legitimate objective." 696 Assessing this presupposes a determination of
both the amended COOL measure's objective and whether this objective is legitimate.697
7.6.2.1 The objective of the amended COOL measure
7.313. In the original dispute, the Appellate Body summarized the "approach to be followed by a
panel in determining the objective a Member seeks to achieve by means of a technical regulation":
That analysis calls for an independent and objective assessment, based on an
examination of the text of the measure, its design, architecture, structure, legislative
history, as well as its operation. While a panel may take as a starting point the

provisions refer to the necessity of the challenged measure." Mexico's first written submission, para. 158
(emphasis added).
691 Mexico's first written submission, para. 158.
692 Mexico's first written submission, para. 158. Canada makes an argument similar to Mexico's in the
context of the risk of non-fulfilment. See Canada's first written submission, para. 116.
693 The Appellate Body held that "the obligation to consider 'the risks non-fulfilment would create'
suggests that the comparison of the challenged measure with a possible alternative measure should be made
in the light of the nature of the risks at issue and the gravity of the consequences that would arise from non-
fulfilment of the legitimate objective. This suggests a further element of weighing and balancing in the
determination of whether the trade-restrictiveness of a technical regulation is 'necessary' or, alternatively,
whether a possible alternative measure, which is less trade restrictive, would make an equivalent contribution
to the relevant legitimate objective, taking account of the risks non-fulfilment would create, and would be
reasonably available." Appellate Body Report, US – Tuna II (Mexico), para. 321. See also Appellate Body
Reports, US – COOL, paras. 377, 378, and 478.

696 Appellate Body Reports, US – Tuna II (Mexico), para. 315.
697 Appellate Body Reports, US – COOL, paras. 313-315 and 371-373. Likewise, as the panel in EC –
Seal Products held, "to assess a measure's consistency with the obligations under Article 2.2 of the
TBT Agreement, the Panel must first identify the objective pursued." Panel Reports, EC – Seal Products,
para. 7.372 (emphasis added). Following its analysis of the objective, the EC – Seal products panel went on to
address "the legitimacy of the identified objective". Panel Reports, EC – Seal Products, section 7.3.3.2. The
original panel's approach was similar: "[h]aving determined the objective pursued by the United States
[through the original COOL measure], [the original panel] proceed[ed] to examine its legitimacy." Panel
Reports, US – COOL, para. 7.628.
WT/DS384/RW • WT/DS386/RW

responding Member's characterization of the objective it pursues through the
measure, a panel is not bound by such characterization. This is so especially where
the objective of a measure is contested between the parties, and competing
arguments have been raised on the basis of the text of the measure, its design,
architecture, structure, legislative history, and evidence relating to its operation.
698
7.314. The parties agree that the amended COOL measure pursues the same objective as the
original COOL measure. 699 What the parties dispute is the precise expression of the objective as
found by the original panel and in particular the Appellate Body. Specifically, the disagreement
concerns whether the objective is generally "the provision consumer information on origin"
(as argued by the complainants)
700, or more specifically to provide information on where livestock
are born, raised, and slaughtered (as argued by the United States).701
7.315. In the original dispute, the Appellate Body identified "the provision of consumer
information on origin" as "what [it] consider[ed] the [original p]anel's understanding of the
objective pursued through the COOL measure to be".
702 The Appellate Body went on to find that
the original panel did not err in identifying the objective pursued through the COOL measure as
being "to provide consumer information on origin". 703 Nevertheless, in a passage relied upon by
the United States, the Appellate Body stated th at "we see no reason to disturb the [original
p]anel's finding with respect to the legitimacy of the objective pursued by the United States
through the COOL measure, namely, to provide consumers with information on the countries in
which the livestock from which the meat they purchase is produced were born, raised, and
slaughtered."
704
7.316. The complainants point out that the more narrow formulation (providing for specific
production steps) appears in the Appellate Body's discussion of the legitimacy of the measure's
objective rather than its identification, and may skew the comparison with alternative measures.705
The United States counters that "the relevant objective can be stated in a number of ways".
While conceding that "it could be stated as 'to provide consumer information on origin'",
the United States argues that "the same objective can be stated in more specific terms, such as
how the Appellate Body has also stated it", and that these "are simply two formulations of the
same objective".
706 The United States adds that the difference in characterization of the objective
is "immaterial" insofar as the Article 2.2 analysis concerns "the degree of contribution to the
objective that a measure actually achieves".
707 In its view, "[t]he degree of contribution to the
objective that the measure actually achieves is the same under either formulation."708

7.317. As the parties point out, the Appellate Body referred to the objective of the original COOL
measure in at least two contexts:
1) in reviewing the original panel's analysis of the original COOL measure's
objective:

"to provide consumer information on origin855"
The parties agree that the amended COOL measure continues to serve the same objective as its
predecessor. The 2013 Final Rule refers to its objective by using a phrase almost identical to that
considered by the original panel in establishing the objective of the original COOL measure.

The 2013 Final Rule did not change the objective of the original COOL measure; rather, it merely

7.319. Nor do we need to choose between the above two formulations by the Appellate Body. It is
sufficient to recall how this matter was resolved in the original dispute. The original panel
identified the objective of the original COOL measure in three places in its report, as follows:
a. "to provide consumer information on origin"
716;
b. "to provide as much clear and accurate information as possible to consumers"717; and
c. "consumer information on origin as declared by the United States."718
7.320. Assessing whether "the [original] Panel Err[ed] in Its Identification of the Objective
Pursued"719, the Appellate Body noted all three formulations of the objective articulated by the
original panel720, and pointed out the "uncertainty in [the original panel's] reasoning" introduced
by "these differing formulations of the objective". 721 To reconcile the original panel's different
formulations, the Appellate Body surmised that the original panel had probably considered the
more general formulation ("the provision of consumer information on origin") as reflecting the
objective, and the more specific one ("the provision of as much clear and accurate origin
information as possible to consumers" 722) as relating to "the level of fulfilment that the
United States desired to achieve."723
7.321. The Appellate Body cautioned against determining "in the abstract" the level at which a
Member seeks to achieve an objective. 724 It confirmed that Members have the freedom to set the
levels at which they wish to achieve a legitimate objective, and that assessing the intended level of
fulfilment was unnecessary. 725 The Appellate Body continued by "identif[ying] what [it]
consider[ed] the [original p]anel's understanding of the objective pursued through the COOL
measure to be[:] … the provision of consumer information on origin".
726 The Appellate Body stated
that, despite the original panel's "segmented" analysis of the objective, "in both instances … the
[original p]anel reached the same result: that the objective that the United States pursues through
the COOL measure is the provision of consumer information on origin." 727 Likewise, in reviewing
Canada's other appeal under Article 11 of the DSU, the Appellate Body noted that "[t]he [original
p]anel concluded, based on the text, design, and structure of the COOL measure, that the COOL
measure's objective is to provide consumer information on origin."728

722 Appellate Body Reports, US – COOL, para. 388 (emphasis original).
723 Appellate Body Reports, US – COOL, para. 388.
724 According to the Appellate Body, "in preparing, adopting, and applying a measure in order to pursue
a legitimate objective, a Member articulates, either implicitly or explicitly, the level at which it seeks to pursue
that particular objective. Neither Article 2.2 in particular, nor the TBT Agreement in general, requires that, in
its examination of the objective pursued, a panel must discern or identify, in the abstract, the level at which a
responding Member wishes or aims to achieve that objective. Rather, what a panel is required to do, under
Article 2.2, is to assess the degree to which a Member's technical regulation, as adopted, written, and applied,
contributes to the legitimate objective pursued by that Member." Appellate Body Reports, US – COOL,
para. 390 (emphasis original).
725 According to the Appellate Body, "the sixth recital of the preamble of the TBT Agreement provides
that a Member shall not be prevented from taking measures necessary to achieve a legitimate objective 'at the
levels it considers appropriate'. … This does no t, however, require a separate assessment of a desired level of
fulfilment." Appellate Body Reports, US – COOL, para. 390, footnote 779; see also para. 373.

WT/DS384/RW • WT/DS386/RW

7.322. The Appellate Body rejected the United States' appeal of the original panel's finding
concerning the COOL measure's "level of fulfilme nt", reiterating that the identification of the
objective should not entail an analysis of the respondent's desired level of fulfilment. 729
Ultimately, the Appellate Body concluded by reconciling all three of the original panel's
formulations of the objective as follows: "we find that the Panel did not err, in paragraphs 7.617,
7.620, and 7.685 of the Panel Reports, in identify ing the objective pursued by the United States
through the COOL measure as being to provide consumer information on origin."730 This is the first
formulation used by the Appellate Body, as invoked by the complainants in this compliance
dispute. It is the formulation of the objective th e Appellate Body chose to use in concluding its
review of the original panel's analysis of the original COOL measure's objective. The same
formulation is reproduced in the conclusions of the Appellate Body reports.
731
7.323. We observe that that the above findin g of the Appellate Body is supplemented by a
footnote referencing the three production steps:
We recall in this respect that the COOL measure defines the "origin" of beef and pork
as a function of the country or countries in which the livestock from which the meat is
derived were born, raised, and slaughtered.732
7.324. However, we do not consider this footnote as part of the Appellate Body's formulation of
the objective. We read it merely as an explan atory remark by the Appellate Body on how the
original COOL measure defined origin.
7.325. The Appellate Body recognized the need to review the challenged measure in determining
the pursued objective. 733 However, the Appellate Body did not equate the measure's design with
the objective pursued through the measure. Rather, it held that the measure might articulate the
desired level of fulfilment 734, while cautioning against a separate assessment of this latter – both
for identifying the objective and for examining an Article 2.2 claim in general. 735 In requiring the
objective's precise identification by panels, the Appellate Body emphasised that this serves to
assess the degree of contribution: "the relevant objective is the benchmark against which a panel
must assess the degree of contribution made by a challenged technical regulation, as well as by
proposed alternative measures."
736
7.326. We consider that the assessment of the de gree of contribution would be confounded and
would become virtually meaningless if the object ive pursued by the amended COOL measure were
to be equated with the way in which the same measure pursues that objective. A meaningful
review of a Member's challenged measure entails a review against objective standards, not those
of the challenged measure itself. Although the A ppellate Body referred to the production steps in
discussing the objective of the COOL measure 737, it did so in the context of reviewing Canada's

729 According to the Appellate Body, "[the United States' appeal] assume[s] that, in identifying the
objective, the Panel was also required to identify the desired "level of fulfilment". We have already explained in
our analysis above why it was not necessary or appropriate for the Panel, in identifying the objective (that is,
to provide consumer information on origin), to further identify the level at which the United States desired to
fulfil its objective of providing consumer information on origin (that is, to provide as much clear and accurate
origin information as possible to consumers). As we noted, the fulfilment of an objective is a matter of degree,
and what is relevant for the inquiry under Article 2.2 is the degree of contribution to the objective that a
measure actually achieves." Appellate Body Reports, US – COOL, para. 426 (emphasis original).

appeal against "the [original p]anel's finding that 'providing consumer information on origin is a
legitimate objective within the meaning of Article 2.2'738".739
7.327. Noting that "Canada ha[d] accepted, at a general level, that the provision of consumer
information on origin can constitute a legitimate objective", the Appellate Body concluded that
Canada "appears to consider that the [original p]anel [had] erred in finding the objective of
providing consumers with information on origin as defined under the COOL measure (that is, based
on where the livestock from which meat is deri ved were born, raised, and slaughtered) to be
legitimate."740 According to the Appellate Body, Canada "seem[s] to imply that, in assessing
legitimacy, a distinction should be drawn between the provision of consumer information on origin,
generally, and the provision of consumer information on origin based on the definition of 'origin'
under the COOL measure."
741
7.328. The Appellate Body refrained from reviewing this possible distinction. It merely noted that
"Canada has not explained why it is not legitimate to define the origin of meat according to the
countries in which the livestock from which it is derived were born, raised, and slaughtered." 742
The Appellate Body added that "[i]t [wa]s therefore unclear on what basis or to what extent, in the
context of its arguments relating to legitimacy , Canada challenges the precise way in which the
COOL measure defines 'origin.'"743
7.329. This lack of clarity was a principal reason for the Appellate Body's conclusion that it "s[aw]
no reason to disturb the [original p]anel's finding with respect to the legitimacy of the objective
pursued by the United States through the COOL measure, namely, to provide consumers with
information on the countries in which the livestock from which the meat they purchase is produced
were born, raised, and slaughtered."
744 As the complainants point out, the Appellate Body was
merely reviewing the original panel's analysis of the objective's legitimacy. After the above
conclusion referring to the production steps, and in the same paragraph, the Appellate Body used
the more general formulation of the objective in its actual finding on legitimacy:
We … dismiss this ground of Canada's appeal and find that the Panel did not err, in
paragraph 7.651 of the Panel Reports, in finding the provision of consumer
information on origin is a legitimate objective within the meaning of Article 2.2 of the
TBT Agreement.
745
7.330. Finally, in the context of its Article 2.1 analysis, the Appellate Body quoted the original
panel's articulation of the objective as "to provide consumer information on origin". 746
The Appellate Body distinguished this from the definition of origin, "under the COOL measure, as a
function of the countries in which the cattle and hogs from which the meat is derived were born,
raised and slaughtered."
747 The Appellate Body considered this latter as "particularly relevant to an
inquiry as to the COOL measure's even-handedness" under Article 2.1, rather than for defining the
original COOL measure's objective.748
7.331. In light of the above, we adopt the Appellate Body's first formulation (without the
footnote) as the identification of the objective of the amended COOL measure: "to provide
consumer information on origin".749

7.6.2.2 Legitimate objective
7.332. The non-exhaustive list of legitimate objectives in Article 2.2 does not specify the provision
of consumer information on origin. As the Appellate Body explained in the original dispute,
assessing an objective not listed in Article 2.2 requires further analysis of the legitimacy of such
objective.
750 Nevertheless, we recall that the original panel found the objective of the original
COOL measure to be legitimate751, and that the Appellate Body upheld this finding, as explained in
the previous section. 752 As noted, the amended COOL measure leaves the objective unchanged.
Further, as the United States points out 753, neither complainant calls into question the legitimacy
of the amended COOL measure's objective in this compliance dispute.754
7.333. Accordingly, there is no reason to re-o pen the issue of legitimacy: the objective of the
amended COOL measure, i.e. to provide consumer information on origin, remains a legitimate
objective under the TBT Agreement.
7.6.2.3 Degree of contribution
7.334. As explained by the Appellate Body
755:
[t]he degree or level of contribution of a technical regulation to its objective is not an
abstract concept, but rather something that is revealed through the measure itself.
In preparing, adopting, and applying a measure in order to pursue a legitimate
objective, a WTO Member articulates, either implicitly or explicitly, the level at which it
pursues that objective.
756 Thus, a panel adjudicating a claim under Article 2.2 must
seek to ascertain—from the design, structure, and operation of the technical
regulation, as well as from evidence relating to its application—to what degree, if at
all
757, the challenged technical regulation, as written and applied, actually contributes
to the achievement of the legitimate objective pursued by the Member.758
7.335. Before assessing the amended COOL measure's degree of contribution, we recall the
relevant findings in the original dispute and the scope of our review of the amended COOL
measure's degree of contribution.
7.6.2.3.1 Relevant findings in the original dispute
7.336. In reviewing the original panel's relevant findings, the Appellate Body noted that,
according to the original panel, "information on the origin of products must be clear and accurate

750 According to the Appellate Body "a 'legitimate objective' refers to an aim or target that is lawful,
justifiable, or proper. Article 2.2 lists specific examples of such 'legitimate objectives', namely: national
security requirements; the prevention of deceptive practices; and the protection of human health or safety,
animal or plant life or health, or the environment. The use of the words 'inter alia' in Article 2.2 introducing
that list, however, signifies that the list of legitimate objectives is not a closed one. In addition, the objectives
expressly listed provide a reference point for other objectives that may be considered to be legitimate in the
sense of Article 2.2. The sixth and seventh recitals of the preamble of the TBT Agreement refer to several
objectives, which to a large extent overlap with the objectives listed in Article 2.2. As the Appellate Body has
also noted, objectives recognized in the provisions of other covered agreements may provide guidance for, or
may inform, the analysis of what might be considered to be a legitimate objective under Article 2.2."

757 (footnote original) This may involve an assessment of whether the measure at issue is capable of
achieving the legitimate objective. (Appellate Body Report, US – Tuna II (Mexico), footnote 640 to para. 317)
758 (footnote original) The Appellate Body explained that, as is the case when determining the
contribution of a measure to the achievement of a particular objective in the context of Article XX of the
GATT 1994, "a panel must assess the contribution to the legitimate objective actually achieved by the measure
at issue." (Appellate Body Report, US – Tuna II (Mexico), para. 317 (referring to Appellate Body Report, China
WT/DS384/RW • WT/DS386/RW

for it to be able to convey meaningful information to consumers." 759 The original panel thus
reasoned that "[u]nder a labelling regime adopted for this purpose, the fulfilment of this objective
will depend on the capability of labels to convey clear and accurate information on origin."
760
7.337. The Appellate Body also noted the original panel's conclusion that, "[ i]n light of the origin
definition as determined by the United States for meat products, the description of origin for
Label B and Label C is confusing in terms of the meaning of multiple country names listed in these
labels. Moreover, the possibility of interchangeably using Label B and Label C for all categories of
meat based on commingling does not contribute in a meaningful way to providing consumers with
accurate information on origin of meat products."
761 The original panel therefore found overall that
the original COOL measure "[did] not fulfil the identified objective within the meaning of Article 2.2
because it fails to convey meaningful origin information to consumers".762
7.338. Conversely, the Appellate Body considered that "[d]espite this overall finding, a number of
findings and observations made by the [original panel] in the course of its analysis belie this
conclusion and suggest that the [original] COOL measure does contribute to the objective of
providing information to consumers on the countries in which the livestock from which meat is
derived were born, raised, and slaughtered"
763:
With respect to Label A, the Panel found that the [original] COOL measure "appears to
fulfil the objective because the measure prohibits [meat derived from animals of non-
US origin] from carrying a Label A". 764 Even with respect to Labels B and C, the Panel
found that these labels provide at least some origin information, namely, "information
on meat with regard to the possible … origin as defined by the measure".
765 Moreover,
the Panel found that, on the whole, the [original] COOL measure provides more
information to consumers than was available to them prior to its enactment. 766 The
Panel also noted that the "labels required to be affixed to meat products … provide
additional country of origin information that was not available prior to the [original]
COOL measure" and that this "may have reduced consumer confusion that existed
under the pre-COOL measure and USDA grade labelling system".
767
7.339. The Appellate Body recalled these findings of the original panel in its attempt to complete
the legal analysis under Article 2.2, and interprete d them as "suggesting that the [original] COOL
measure does contribute, at least to some degree, to providing consumers with information on
origin".
768 Overall, the Appellate Body concluded that "the findings of the [original panel] and
undisputed facts on the record indicate that the labelling requirements under the [original] COOL
measure make some contribution to the objective of that measure", but did not consider these
findings sufficient "to ascertain the degree of contribution made by the COOL measure to such an
objective."
769
7.340. A specific point addressed by the Appellate Body was the "implications of the
[original panel's] findings for assessing the contri bution made by Label A to the objective of the

763 Appellate Body Reports, US – COOL, para. 466 (emphasis original).
764 (footnote original) Panel Reports, para. 7.713. The finding of the Panel in its entirety is as follows:
In essence, the specific objective pursued by the United States through the
COOL measure as explained above, namely the prevention of confusion
caused by the previous COOL regime as well as USDA grade labelling, is
that the United States aims to prevent meat derived from animals of
non-US origin from carrying a US-origin label under any circumstances. To
that extent, the COOL measure appears to fulfil the objective because the
measure prohibits such meat from carrying a Label A even though the
same meat may still carry a USDA grade label.
766 (footnote original) According to the Panel, the COOL measure provides "more information than under
the previous labelling regime". (Panel Reports, para. 7.715 (emphasis original))

COOL measure, both in terms of the proportion of meat sold in the United States that carries this
label, and in terms of the clarity and accuracy of the information Label A conveys". 770 In this
connection, the Appellate Body recalled the "conside rable proportion of beef and pork [that was]
exempted from the [original] COOL measure" and the "vast majority" of meat covered by the
original COOL measure that would carry Label A.771
7.341. The Appellate Body also reviewed "multi ple examples of ways in which the labelling
scheme prescribed by the [original] COOL measure provides unclear, imperfect, or inaccurate
information to consumers, in particular with respect to Labels B and C". 772 This included the failure
of these labels to "deliver origin information as defined under the measure or as the consumer
might understand it", and the "confusion" in cases where packages containing a single piece of
meat would list multiple countries on the label.
773
7.342. The Appellate Body also cited the original panel's doubt that "differentiation of origin based
on the order of country names will indeed communicate accurate origin information".774 Further, as
a result of the commingling flexibilities, the Appellate Body noted the original panel's finding that
"not even a 'perfect consumer who is fully informed of the meaning of different categories of labels
under the [original] COOL measure' could ever 'b e assured that the label precisely reflects the
origin of meat as defined under the [original] COOL measure'".775
7.6.2.3.2 Scope of review of the amended COOL measure's degree of contribution
7.343. In addition to Labels A-C, the complainants include references to Category D muscle cuts
and the ground meat label (Label E) in support of their Article 2.2 claims. 776 In the context of
analysing legitimate regulatory distinctions under Article 2.1 of the TBT Agreement, we addressed
the parties' disagreement as to which aspects of the amended COOL measure were relevant to our
analysis.777 In that context, we noted the Appellate Body's clarification that "in answering the
question of whether the measure gives accurate information to consumers, all distinctions drawn
by the measure are potentially relevant. By contrast, in an analysis under Article 2.1, we only need
to examine the distinction that accounts for the detrimental impact". 778 The Appellate Body made
this statement in relying on findings under Articl e 2.2 of the TBT Agreement to complete the legal
analysis of "whether the measure is calibrated for the purposes of Article 2.1".779
7.344. In principle, Label D (muscle cuts fr om foreign-slaughtered animals) and Label E
(ground meat) could potentially be relevant for our assessment of Article 2.2 – including for the
amended COOL measure's degree of contribution – irrespective of whether these labels account for
any detrimental impact or constitute relevant regulatory distinctions under Article 2.1. However,
the complainants have unequivocally stated that in this compliance dispute they are not bringing
claims with respect to Labels D and E.
780 As explained below 781, the alternative measures they
have proposed under Article 2.2 specifically apply only to US-slaughtered muscle cuts that would
be eligible for Labels A-C. The complainants provide no indication of how the conclusions from a
relational analysis based on all distinctions of the amended COOL measure could be meaningfully
compared to alternative measures pertaining only to Labels A-C.
7.345. Thus, including Labels D and E in our relational analysis under Article 2.2 would not be
consonant with the manner in which the complainants have presented their arguments, and could
prejudice a comparative analysis under the same provision. As the Appellate Body held in US –

Tuna II (Mexico), examining alternative measures that do not align with the scope of a relational
analysis can result in "an improper comparison"782 amounting to legal error under Article 2.2 of the
TBT Agreement. 783 Accordingly, we do not examine aspects of the measure in our relational
analysis which the complainants do not challenge and which they exclude in their arguments under
the comparative analysis.
7.6.2.3.3 The amended COOL measure's degree of contribution
7.346. As outlined above, the Appellate Body assessed the original COOL measure's degree of
contribution to its objective by considering two main criteria: the proportion of muscle cuts in the
United States that actually carry labels as well as the degree of clarity and accuracy of such
labels.
784 These factors are equally relevant for reviewing the degree of contribution of the
amended COOL measure to its objective.
7.347. The objective of the amended COOL measure is to provide consumer information on origin.
The proportion of muscle cuts that are actually labelled, as opposed to those that are exempted,
is the initial determinant of the degree to which the amended COOL measure is capable of fulfilling
its objective. This is because, logically, no origin information is conveyed on a mandatory basis for
muscle cuts falling within in the amended C OOL measure's three exemptions. As noted,
the amended COOL measure only covers between 33.3% and 42.3% of all beef consumed in the
United States, and between 15.9% and 16.5% of all pork muscle cuts. Conversely, between
57.7% and 66.7% of all beef consumed in the United States, and between 83.5% and 84.1% of all
pork muscle cuts, are either sold in a food servic e establishment, as an ingredient in a processed
food item, or by an entity not subject to be licensed as a "retailer".785 This represents a substantial
portion of beef and pork 786 for which the amended COOL measure does not contribute at all to
providing consumer information on origin. Hence, the degree of contribution of the amended COOL
measure for this substantial portion of products is zero.787
7.348. Origin information could be conveyed only on the portion of muscle cuts that is actually
required to be labelled. Labels A-C are the labels that have been most significantly revised by the
2013 Final Rule. The introduction of point-of-production information on Labels A-C represents a
clear improvement of the information formerly pr ovided under the original COOL measure. The
original panel pointed out that the limited contribution of "providing general information about the
various countries in which an animal ha[d] spent time and [been] slaughtered" was not in keeping
with the United States' definition of "the origin of meat based on the place where animals from
which meat was derived were born, raised, and slaughtered".
788 As a result of the 2013 Final Rule,

782 Appellate Body Report, US – Tuna II (Mexico), para. 328.
783 Appellate Body Report, US – Tuna II (Mexico), para. 331.
784 The Appellate Body noted in the original dispute that "[w]hen it came to actually applying a standard
of 'fulfilment' to the [original] COOL measure, the [original p]anel noted that, as the parties agreed,
information on the origin of products must be clear and accurate for it to be able to convey meaningful
information to consumers. Therefore, '[u]nder a labelling regime adopted for this purpose, the fulfilment of this
objective will depend on the capability of labels to convey clear and accurate information on origin'."
Appellate Body Reports, US – COOL, para. 463 (emphasis by the Appellate Body) (quoting Panel Reports, US –
COOL, para. 7.695). The Appellate Body also noted that "[o]n appeal, the participants disagree as to the
implications of the [original p]anel's findings for assessing the contribution made by Label A to the objective of
the [original] COOL measure, both in terms of the proportion of meat sold in the United States that carries this
label, and in terms of the clarity and accuracy of the information that Label A conveys." Appellate Body
Reports, US – COOL, para. 474.
785 See paras. 7.258 and 7.262 above. The parties do not indicate that these shares have changed
under the original and the amended COOL measures.
786 The above figures correspond to all beef consumed in the United States, including Categories A-C,
imported muscle cuts (Category D), and ground meat (Category E). In the case of pork, data provided by
Canada and the United States show that ground pork comprises a negligible share of total US pork
consumption. See parties' responses to Panel question A; Exhibit US-59. Therefore, the figures provided for
pork only relate to muscle cuts. As regards beef, these figures are thus an indicative approximation of the
extent to which the exemptions prevent any contribution to the COOL objective. However, we are unable to
determine the proportion of exempted products within Categories A-C specifically. For pork, these figures more
closely overlap with the products under review, namely those falling in Categories A-C.
787 We recall the Appellate Body's statement that the degree of contribution "may involve an assessment
of whether the measure at issue is capable of achieving the legitimate objective". Appellate Body Reports, US –
COOL, footnote 928 (emphasis added).
WT/DS384/RW • WT/DS386/RW

the amended COOL measure provides consumer information that now largely corresponds to the
measure's definition of origin by requiring labels that specify the country(ies) of birth, raising, and
slaughter.789
7.349. The original COOL measure's contribution to its objective was supported by the findings
"that Label A ensures 'meaningful information for consumers'" 790 and by the exclusive reservation
of Label A for muscle cuts solely from US-origin animals. 791 The conveyance of meaningful
information on Label A is even greater under th e amended COOL measure, which also maintains
the exclusivity of Label A for products from animals that were exclusively born, raised, and
slaughtered in the United States.792
7.350. With respect to Labels B and C, the requirements under the original COOL measure
evidenced a lower degree of contribution to the objective due to inter alia the commingling and
country order flexibilities. 793 As the original panel held, "the different and complex categories of
labels under the [original] COOL measure and th e operation of the COOL regime based on the
commingling provisions render origin information contained in labels inaccurate and confusing." 794
We note that, under the modified requirements of the amended COOL measure, the requirement
of point-of-production information and the removal of commingling on Labels B and C remedy
many of the sources of inaccuracy found in the original dispute.
7.351. In particular, the amended COOL measure effectively distinguishes Labels B and C in a
manner that was not the case under the original COOL measure. Label B is now required to include
the United States as a country of raising, with th e additional possibility of including other foreign
countries of raising.
795 This appears to take care, in particular, of labelling the origin of foreign,
and in particular Mexican, cattle also grazing in the United States before being slaughtered there.
Label C is required to indicate the country from which livestock were imported as a country of
raising. Only in the event that an animal imported for immediate slaughter also spent some
amount of time in the United States – and depending on the interpretation of the applicable
rules
796 – could Label C possibly include the United States as a country of raising. However, the
evidence shows that, in practice, Category C livestock are typically of solely Canadian origin prior
to US-slaughter. Hence, it does not appear that Label C would be likely to indicate the
United States as a country of raising in a typical Category C scenario.797
7.352. In light of the above, the amended C OOL measure makes "some contribution" to the
objective of providing consumer information on origin. For covered products, the amended COOL
measure contributes to the relevant objective to a greater degree than the original COOL measure.
As regards non-covered products, the amended COOL measure continues to exempt
"a considerable proportion of beef and pork"
798 for which it does not contribute at all to the
objective of providing consumer information on origin.
7.353. Ascertaining the amended COOL measure's precise degree of contribution requires further
scrutiny of the information actually provided on labels for the covered products relevant to our
analysis. On the one hand, the majority of muscle cuts that are actually labelled under the
amended COOL measure will be eligible for Label A, which continues to provide "meaningful
information for consumers"
799 in accordance with the definition of origin based on birth, raising,
and slaughter. Muscle cuts carrying Labels B an d C will similarly provide point-of-production
information according to rules that will likely operate to distinguish the two labels. The elimination

WT/DS384/RW • WT/DS386/RW

of the commingling and country order flexibilities generally remedies the original COOL measure's
potential to provide misleading and inaccurate information through overlapping possibilities of
Labels A-C.
800
7.354. On the other hand, the degree of contribution achieved for Labels A-C is limited to some
extent by the potential inaccuracy and incompleteness of information with respect to the
country(ies) of raising. As noted, under certain conditions, the amended COOL measure allows
omission of non-US countries of raising from the label even though an animal may have spent a
substantial portion of its life outside the United States and as little as 15 days inside the
United States before slaughter.
801 This potential for inaccurate or incomplete information lowers
the amended COOL measure's degree of contribu tion for Category B muscle cuts. Conversely,
Category A muscle cuts have only US origin and, as explained, Category C muscle cuts would
typically show that only the animal's slaughter occurred in the United States.802
7.355. As to the appearance and placement of labels, we recall that the amended COOL measure
allows for some discretion as to how retailers convey country of origin information to consumers,
while stipulating that flexibilities as to label placement and abbreviation "are permitted as long as
the information can be clearly understood by consumers". 803 Based on the evidence of actual
labels submitted, we cannot draw conclusions about label accuracy from this labelling discretion
and consequently are unable to determine its implications for the amended COOL measure's
degree of contribution to providing consumer information on origin.804
7.356. In conclusion, we find that the amended COOL measure contributes to the objective of
providing consumer information on origin to a significant degree for products carrying Labels A-C.
At the same time, the amended COOL measure does not make any contribution for products
exempted from its coverage that would otherwis e carry such labels. Overall, the amended COOL
measure thus makes a considerable but necessarily partial contribution to its objective of providing
consumer information on origin.
7.6.3 The amended COOL measure's trade-restrictiveness
7.357. The parties concur
805 that trade-restrictiveness means "having a limiting effect on
trade"806. However, they disagree how this should be assessed in the context of Article 2.2 of the
TBT Agreement.
7.358. The complainants consider that trade-restrictiveness amounts to affecting the conditions of
competition to the detriment of imported products.807 They refer808 to the original panel's approach
and finding in this regard 809, which, they point out, the Appellate Body did not modify. 810
They note that the original panel found that, due to segregation, the original COOL measure
altered the conditions of competition to the detriment of imported livestock. 811
The complainants refer to their arguments under Article 2.1 of the TBT Agreement, and contend
that the amended COOL measure continues to alte r, and in fact aggravates, the conditions of
competition to the detriment of imported livestock. 812 They note that in the context of Article 2.2,
the Appellate Body relied on the original panel's analysis of detrimental impact to find that the

original COOL measure had a "considerable degree of trade-restrictiveness"813, and assert that this
is aggravated under the amended COOL measure.814
7.359. The United States concedes that th e amended COOL measure is trade restrictive. 815
However, according to the United States, trade-re strictiveness refers to the restriction of trade
flows, not to discrimination 816, which is "subject to a separate provision". 817 The United States
recalls that Articles 2.1 and 2.2 of the TBT Agreement are "separate obligation[s]", and "Article 2.2
is not a specific application of Article 2.1".
818 The United States notes that in US – Tuna II
(Mexico), the Appellate Body cautioned that the analysis under one Article is not dispositive of the
other819, and determined that the challenged measure in that dispute was inconsistent with
Article 2.1, while not inconsistent with Article 2.2.820
7.360. The United States adds 821 that Article 2.2 was interpreted as allowing for "some trade-
restrictiveness"822, and argues that "it is impossible to square this approach with the complaining
parties' contention that the term 'trade-restrictive' refers to discrimination" because "[i]t simply
does not make sense to discuss how Article 2.2 allows for 'some' discrimination."
823 According to
the United States, the Appellate Body noted that "w hat Article 2.2 disciplines is 'trade restrictive
effect'".824 Accordingly, the United States contends, trade-restrictiveness should be interpreted as
limiting market access,825 and it should be assessed in a purely quantitative analysis.826
7.361. Canada responds that the concept of trad e-restrictiveness under the TBT Agreement is not
different from the same concept under the GATT 1994 827, and does not require the demonstration
of actual trade effects, as the original panel recalled. 828 Canada notes that the Appellate Body
established that the original COOL measure was trade-restrictive by referencing the Article 2.1
findings of the original panel as demonstrating a "considerable degree of trade restrictiveness
insofar as [the original COOL measure] ha[d] a limiting effect on the competitive opportunities for
imported livestock".
829 Canada recalls that the Appellate Body added that "[t]his was confirmed by
the Panel's analysis of the actual trade effects of the COOL measure." 830 According to Canada, this
shows that trade-restrictiveness may be expressed in qualitative terms.831
7.362. Mexico adds that the original panel "examined the meaning of the term
'trade-restrictive'832, reviewed the applicable GATT and WTO jurisprudence 833, and concluded
(i) that 'the scope of the term 'trade-restrictive' is broad' 834 and (ii) that the concept of
'trade-restrictiveness' 'does not require the demonstration of any actual trade effects, as the focus

is on the competitive opportunities available to imported products' 835."836 Mexico recalls that
"[t]he [original p]anel's ultimate conclusion that the COOL measure is 'trade-restrictive' within the
meaning of Article 2.2 by affecting the competitive conditions of imported livestock was accepted
by the Appellate Body
837."838 Quoting the Appellate Body's relevant findings 839, Mexico argues that
"[t]he Appellate Body has clearly stated that the [original p]anel's finding in the original
proceedings that the COOL Measure denied equal competitive opportunities was sufficient to
establish a 'considerable degree of trade-restrictiveness insofar as it has a limiting effect on the
competitive opportunities for imported livestock.'
840"841 Mexico adds that it has demonstrated the
trade-restrictiveness of the amended COOL measur e by showing evidence similar to that taken
into account by the Appellate Body.842
7.363. As the parties note, the Appellate Body summarized the legal test of trade-restrictiveness
under Article 2.2 of the TBT Agreement as follows843:
By its terms, Article 2.2 requires an assessment of the necessity of the
trade-restrictiveness of the measure at issue. In this regard, the Appellate Body in US
– Tuna II (Mexico) defined "trade-restrictive" to mean "having a limiting effect on
trade".844 Moreover, it found that the reference in Article 2.2 to "unnecessary
obstacles" implies that "some" trade-restrictiveness is allowed and, further, that what
is actually prohibited are those restrictions on international trade that "exceed what is
necessary to achieve the degree of contribution that a technical regulation makes to
the achievement of a legitimate objective".
845
7.364. In attempting to complete its Article 2.2 analysis in the original dispute, the Appellate Body
noted the original panel's "finding that the COOL measure is '"trade-restrictive" within the meaning
of Article 2.2 by affecting the competitive conditions of imported livestock'." 846 The Appellate Body
also noted the original panel's distinction between the focus on competitive opportunities and
actual trade effects: "the scope of the term 'trade-restrictive' is broad and 'does not require the
demonstration of any actual trade effects, as the focus is on the competitive opportunities
available to imported products'."847
7.365. The Appellate Body then recalled848 the original panel's main findings under Article 2.1 with
regard to changes to the "conditions of competition" between US and foreign livestock resulting
from the original COOL measure.
849 In particular, the Appellate Body noted that the original panel
had "found that 'by imposing higher segregation costs on imported livestock", the original COOL
measure negatively affects the conditions of competition of imported livestock vis-à-vis like
domestic livestock in the US market.'850"851
7.366. Based on this summary of the original pa nel's main Article 2.1 findings on changes to
competitive conditions, the Appellate Body established that the original COOL measure was trade-
restrictive within the meaning of Article 2.2. Th e Appellate Body further determined the original
COOL measure's degree of trade-restrictiveness:

WT/DS384/RW • WT/DS386/RW

[A]lthough the Panel declined to make a find ing "on the level of trade-restrictiveness"
of the COOL measure, its findings suggest it considered the measure to have a
considerable degree of trade-restrictiveness insofar as it has a limiting effect on the
competitive opportunities for imported livestock as compared to the situation prior to
the enactment of the COOL measure.
852
7.367. As the complainants point out, it is only after having reached this conclusion that the
Appellate Body referenced the original panel's finding on actual trade effects, stating that "[t]his
was confirmed by the [original p]anel's analys is of the actual trade effects of the COOL
measure."853
7.368. In light of the findings in the original dispute, we are unable to accept the argument that
trade-restrictiveness under Article 2.2 is limited to actual and quantifiable effects on trade or
market access. Instead, following the Appella te Body's approach, we review the trade-
restrictiveness of the amended COOL measure by relying on our findings under Article 2.1
concerning the amended COOL measure's detrimental impact on the competitive conditions for
imported livestock.
7.369. As noted, the United States also accepts that the amended COOL measure is trade
restrictive.
854 We have found that the amended COOL measure increases the detrimental impact
on the competitive opportunities of imported livesto ck as compared to the original COOL measure.
We have concluded that this is corroborated by witness statements, and that it is also confirmed to
some extent by economic and econometric eviden ce submitted by Canada on the actual trade
effects of the amended COOL measure.
7.370. Given the increased detrimental impact on the competitive opportunities of imported
livestock, we conclude that the amended COOL measure has increased the "considerable degree of
trade-restrictiveness" found by the A ppellate Body in the original dispute.
855 We recall, however,
that although a labelling scheme may entail some degree of trade-restrictiveness, the trade-
restrictiveness of a challenged measure constitutes only one factor of the legal test, and does not
alone amount to a violation of Article 2.2 of the TBT Agreement.
856
7.6.4 Risks of non-fulfilment of the amended COOL measure's objective
7.371. In assessing whether a technical regulation is "more trade-restrictive than necessary to
fulfil a legitimate objective", Article 2.2 of the TBT Agreement mandates taking into account
"the risks non-fulfilment [of a legitimate objective] would create." According to the Appellate Body,
this is a "further element of weighing and balancing"
857 under Article 2.2.
7.372. We have found that the objective of th e amended COOL measure remains the provision of
consumer information on origin858, and that this is a legitimate objective.859
7.373. Both Canada and Mexico argue that the risks of non-fulfilment of the amended COOL
measure's objective are low860, partly as a result of what the complainants allege is US consumers'
lack of interest in country of origin information and due to their unwillingness to pay for the
information.861 The United States counters that US consumer interest in country of origin labelling

is high862, and that consumers are willing to pay for the information conveyed on labels under the
amended COOL measure.863
7.6.4.1 Legal test and relevant factors
7.374. According to the Appellate Body, reviewing "the risks non-fulfilment [of a legitimate
objective] would create" entails assessing "the nature of the risks at issue and the gravity of the
consequences that would arise from non-fulfilment of the legitimate objective".
864
7.375. Article 2.2 provides that "[i]n assessing … risks, relevant elements of consideration are
inter alia: available scientific and technical information, relayed processing technology or intended
end uses of products." The complainants' relevant arguments and evidence address only what
could be considered technical information relating to consumer interest in, and willingness to pay
for, origin information. In the original dispute, the Appellate Body briefly addressed the risks non-
fulfilment of the original COOL measure's objective would create by taking into account consumer
interest in, and willingness to pay for, country of origin information.
865 Like the Appellate Body, we
address these factors for the risks non-fulfilment of the amended COOL measure's objective would
create.
7.376. In response to the Panel's question on th e elements for assessing the risks non-fulfilment
of the objective would create, Mexico points out that Article 2.2 contains an illustrative list and
that "the context of Article 2.2 (in particular, explicit requirement for the assessment of such risks,
indication of relevant elements for conducting the assessment) suggests that the Panel should
examine whether actual risks exist."
866 However, Mexico does not explain how an assessment of
actual risks should be carried out or how such assessment may differ from assessing the risks non-
fulfilment of the amended COOL measure's objectives would create.
7.377. Canada suggests several additional factors for assessing the risks non-fulfilment of the
amended COOL measure's objective would create. In particular, Canada refers to "whether the
information is provided for a broad range of products and to what extent products in a category of
the measure are covered." 867 Canada argues that "[i]n this case, while the amended COOL
measure applies to a series of categories of produc ts, it applies to only a small proportion of beef
and pork."868 This is an issue we have addressed in the context of legitimate regulatory distinctions
under Article 2.1 and also in our Article 2.2 an alysis of the amended COOL measure's degree of
contribution to its objective. Hence, we see no reason to address this factor again in the context of
the risks non-fulfilment of the amended COOL measure's objectives would create.
7.378. Canada also suggests that we address "[w]hether the information relates to risks to
human or animal health, safety or the environment or is provided for any other serious reasons
related to the protection of the public."
869 Canada argues that "[i]n this case, none of those
reasons applies."870 This suggested element is related to a more general argument Canada makes
on the relative importance of values and interests protected by the measure. Relying on the
necessity test of Article XX of the GATT 1994, Cana da argues that "the more important the values
or interests underlying the objective – that is, the greater the risks and severity of the
consequences of not achieving the objective, the more likely it is that a restrictive measure will be
found to be 'necessary'
871."872 Canada thus suggests that the relative importance of values or

values are, the easier it would be to accept as 'necessary' a measure designed as an enforcement instrument."

interests that it is the objective of the measure to protect is directly linked to the risks
non-fulfilment would create under Article 2.2 of the TBT Agreement.
7.379. We have held that the relative importance of interests or values protected by a measure is
not a separate factor of the Article 2.2 legal test. 873 We do not exclude the possibility for overlap
between analytical components of the legal obli gations of the TBT Agreement and the GATT 1994.
The Appellate Body has held that "the two Agreem ents should be interpreted in a coherent and
consistent manner."874 Ultimately, however, the text of the TBT Agreement requires us to assess
the necessity of a technical regulation's trade-re strictiveness by "taking account of the risks non-
fulfilment would create".875 In the Appellate Body's reading, this factor of an Article 2.2 analysis is
to be examined according to two criteria: th e nature of the risks and the gravity of the
consequences. We need not define the precise relationship between the nature of risks and gravity
of the consequences of the non-fulfilment of a le gitimate objective under the TBT Agreement, on
the one hand, and the relative importance of the interests or values protected under Article XX of
the GATT 1994, on the other. We confine our analys is to the express terms of the TBT Agreement,
as clarified by the Appellate Body, instead of defining the precise relationship between terms in the
TBT Agreement and the GATT 1994.
7.380. Finally, Canada suggests that we assess risks according to "[w]hether the design and
architecture of the measure consistently reflect the importance of the objective."
876 Canada argues
that "[i]n this case, there is no logic to the proposition that consumers interested in origin
information care less when buying ground meat, or when buying meat in restaurants, in butcher
shops or in the form of processed food."
877 We note that there may be a variety of possible
reasons unrelated to risks for exempting or treating differently certain product categories under a
Member's technical regulation, such as regulatory or compliance costs. Further, we consider that
the amended COOL measure's treatment of different categories of meat products is more directly
connected to the degree of contribution under Article 2.2 and the legitimacy of regulatory
distinctions under Article 2.1.
878 To the extent that Canada's suggestion concerns the relative
importance of the amended COOL measure's objective, we have explained the legal test that it is
our task to apply to the complainants' Article 2.2 claims, including as regards the risks non-
fulfilment would create.
7.381. In light of the above, we review the ri sks non-fulfilment of the amended COOL measure's
objective would create by assessing the nature of the risks and the gravity of the consequences.
We do this by assessing consumer interest in, and willingness to pay for, country of origin
information, in accordance with the Appellate Body's approach in the original dispute.
7.382. The parties argue that each other's evidence on consumer interest and willingness to pay
is either irrelevant 879, or biased 880 and of dubious scientific value. 881 As the Appellate Body
explained, Article 11 of the DSU requires a panel to "consider all the evidence presented to it,
assess its credibility, determine its weight, and ensure that its factual findings have a proper basis

in that evidence."882 We are also mindful that we "are not required to accord to factual evidence of
the parties the same meaning and weight as do the parties."883
7.383. Accordingly, we carry out a critical assessment of the evidence submitted by the parties on
consumers' interest in, and willingness to pay for, country of origin information. As we consider
that these are two facets of consumer demand for origin information, we assess them separately.
In light of the parties' arguments and for the sake of completeness, we address the parties'
evidence both in terms of general country of origin information and in terms of point-of-production
origin information according to the country of birth, raising, and slaughter.
884
7.6.4.2 Consumer interest
7.6.4.2.1 Consumer interest in general country of origin information
7.384. The complainants submit various studies in support of their argument that US consumers
do not have an interest in country of origin information.
885
7.6.4.2.1.1 Summary KSU Study Fact Sheet and KSU studies
7.385. The complainants contend that mandatory country of origin labelling has not brought about
any identifiable changes to consumer demand for the products subject to the disputed labelling
rules relative to the products exempt from labelling. 886 Canada submits an article, the summary
KSU Study Fact Sheet, which summarizes the first known post-implementation assessment of how
consumer demand has been influenced by mandatory country of origin labelling rules in the
United States.887 The methodology of the KSU Study Fact Sheet and the underlying assessments
are contained in two separate studies, KSU Revealed Demand 888 and KSU Consumer Valuation,
each submitted by both complainants. 889 According to the KSU Revealed Demand study, relative
demand for covered meat products has not change d following the implementation of the original
COOL measure. 890 According to the KSU Study Fact Sh eet, the KSU Consumer Valuation study
shows that US consumers are unaware of the measure and do not look for meat origin
information.891
7.386. We are not persuaded of the relevance of the two KSU studies and the summary KSU
Study Fact Sheet for our findings on consumer demand for general country of origin information.
7.387. As regards the KSU Revealed Demand stud y, it demonstrates unchanged relative demand
for the products covered by the original COOL measure. However, we are unable to conclude from
this study that this unchanged demand is necessarily attributable to a lack of interest in the type
of information mandated by the original COOL me asure. There could be various reasons for which
relative demand for the covered and exempted products has remained steady. For example,
consumers might have found the labels confusing
892, and demand for both the covered and

883 Appellate Body Report, Australia – Salmon, para. 267.
884 In fact, despite finding that the objective of the original COOL measure was the provision of
consumer information on origin, in reviewing the risks non-fulfilment would create the Appellate Body
referenced both "country of origin labelling of beef and pork" in general, and specific "information on the
countries of birth, raising, and slaughter of livestock". Appellate Body Reports, US – COOL, para. 478.

COOL, paras. 7.653, 7.655-7.658, 7.660, and 7.676. In US – COOL the Appellate Body observed that "with
respect to meat bearing Labels B and C, however, any contribution made [to the fulfilment of the original COOL
measure's legitimate objective] is much more limited because the information may be confusing and
inaccurate". Appellate Body Reports, US – COOL, para. 476. See also Canada's first written submission,
paras. 77 and 151; and Mexico's first written submission, para. 176.
WT/DS384/RW • WT/DS386/RW

exempted products might be inelastic for reasons unrelated to the measure, such as consumer
preferences for specific types of meat or ot her foodstuffs. As the United States notes,
the complainants "fail to explain how a change in a consumer's purchasing patterns is probative of
consumer demand for the provision of certain information, which only constitutes one element of
decision making."
893
7.388. The KSU Revealed Demand study concludes that there is a net economic welfare loss
because of the combined effect of steady dema nd for the covered products and labelling costs. 894
We have not been persuaded that there is a dire ct link between this conclusion and consumer
interest in general country of origin information. The KSU Revealed Demand study relies on
grocery-store sales data for the covered products and a number of other products over a period of
time. This, however, has no direct bearing on whether consumers buying the covered products
have experienced an increase in welfare as a result of country of origin information. Indeed, as the
USDA explains, even if "the economic benefits from the COOL requirements are positive", they are
"difficult to quantify".
895 The KSU Revealed Demand study addresses net economic welfare for
producers and consumers in terms of variables that do not capture specific consumer welfare, let
alone consumer interest in country of origin information.
7.389. Turning to the KSU Consumer Valuation survey, it finds that US consumers are largely
unaware of the original COOL measure and its legal status. 896 The complainants reference this as
further demonstration of consumers' low interest in country of origin labelling. 897 However, this
assumes that consumer awareness of a given measure is a reliable proxy for consumer interest in
the objective of that measure. Absent substantiation of such an assumption, we question the
relevance of US consumers' awareness of the amended COOL measure for our consideration of
consumer interest in general country of origin information.
7.390. Finally, according to the summary KSU Stud y Fact Sheet, a typical US consumer does not
look for meat origin information.
898 A s f a r a s w e c a n t e l l f r o m t h e K S U S t u d y F a c t S h e e t , t h i s
conclusion is based on in-person surveys and experiments that were conducted in grocery stores
in Texas in 2012. The results seem to have been reported in a working paper from 2012,
referenced in the KSU Study Fact Sheet as "Klain et al, 2012". However, this working paper has
not been submitted by any of the parties. Having reviewed the underlying studies before us for the
KSU Study Fact Sheet (i.e. the KSU Revealed De mand and KSU Consumer Valuation studies), we
find no specific, detailed explanation for the KSU Study Fact Sheet's conclusion.
7.6.4.2.1.2 Studies on food values
7.391. Canada submits a study pertaining to US consumers' preferred food values
899 in support of
its argument that origin information is among the least important food values for US consumers.900
As regards its methodology, the survey acknowledges that it involved a small and not necessarily
fully representative sample of US consumers. 901 The consumers consulted were not asked
questions about meat in particular, but about food in general. 902 As borne out by the evidence put
forth by the United States in the context of willingness to pay, "the value of country-of-origin
information is product specific even within a product category (e.g. meat)." 903 Based on the

893 United States' comments on responses to Panel question No. 13. The same reservations apply to a
study submitted by Mexico with regard to demand for shrimp, which, like KSU Revealed Demand study, shows
no change in demand for shrimp following the original COOL measure's entry into force. Exhibit MEX-36.

that presented here should be repeated with a larger and more representative sample of consumers", and the
study's sample is characterised as "somewhat small". Exhibit CDA-85, pp. 193-194.

evidence before us, we have no reason to consid er that consumer interest in general country of
origin information would not be similarly product specific.
7.392. Canada also submitted a working paper applying a similar methodology as the
aforementioned study that relates specifically to meat, as well as other products. 904 This working
paper involved a larger, more representative sample of consumers who were asked specifically
about food values in relation to ground beef, beef steak, chicken breast, and milk. 905 The working
paper concludes that, compared to other food values, such as food safety, consumers do not value
origin highly.
7.393. The questions posed in the working paper referenced origin as follows: "the extent to
which the locations and identities of producers and processors are known". 906 We are not inclined
to rely on this evidence as proof of consumer general interest in covered products' country of
origin, given that origin has been referenced very differently from its definition in the original and
amended COOL measures. For us, it cannot be ex cluded that consumers might have answered
differently had origin been defined more consistently with the original or amended COOL
measures.
7.394. In any event, any relevance of the re sults of the above-mentioned study and working
paper submitted by Canada on food values is at most indirect for our purposes. Both documents
were designed in a way that enquired about food origin in relation to other values. 907 That
consumers may value origin less than other values does not necessarily speak to the absolute
value consumers attach to origin.
7.6.4.2.1.3 Letters and opinion polls submitted by the United States
7.395. The United States submits evidence in th e form of letters of support from individuals,
consumer groups, and associations, and opinion polls conducted domestically, with a view to
demonstrating that there is considerable consumer interest in country of origin labelling in
general.
908
7.396. Much of this evidence was also submitte d by the United States in the original dispute. 909
In the context of reviewing the original COOL measure's objective, the original panel observed that
the evidence "generally refers to comments made during the legislative process, hence it may not
necessarily prove … consumer demand calling for the pursuit of the stated objective". 910
Assessing the risks non-fulfilment of the amended COOL measure's objective would create,
the Appellate Body held that the original panel had thus "cast doubt" on the probative value of the
evidence that the United States adduced to demonstrate consumer interest.
911 The same might
apply to a significant proportion of the letters and polls submitted by the United States in this
compliance dispute.

2010, was not submitted in the original dispute.

WT/DS384/RW • WT/DS386/RW

7.397. The relevant piece of US evidence before this compliance Panel, but not the original panel,
is an opinion poll based on telephone interviews conducted in October 2010. The poll was based on
responses from 1014 individuals to the following question:
Suppose a cow is born and raised in Mexico, and then sent to the U.S. to be fattened
for two months, slaughtered and sold. If you saw the meat from this animal in your
supermarket, which of the following labels would you prefer it to have?
 Product of U.S. and Mexico
 Product of Mexico
 Product of U.S.
 Other (specify)
 Don't know
912
7.398. The poll concludes that "[n]early half (47%) of consumers said they prefer comprehensive
labeling – the label for meat from an animal raised both in the U.S. and Mexico should reflect the
animal's complete history."
913
7.399. We note that the poll, in particular the question and the possible categories of responses,
assumes that consumers would like some form of origin labelling. In fact, the poll does not
explicitly ask whether or not consumers would like to have meat carry labels with origin
information. Rather, the question focuses on what kind of information should be shown on the
label. Accordingly, we cannot assume that 47% of the consumers consulted, let alone 47% of all
US consumers, would actually be interested in having a meat label with country of origin
information. This poll – together with the other letters and poll submitted by the United States –
only suggests that there is some consumer interest in country of origin information in general.
7.6.4.2.2 Consumer interest in point-of-production origin information
7.400. The complainants submit no evidence pert aining in particular to consumer interest in
point-of-production information on the animal's place of birth, raising, and slaughter.
7.401. The above-mentioned studies invoked by the complainants
914 do not contain any findings
with regard to labelling specifically in accord ance with the requirements of the amended COOL
measure, which, as explained earlier915, differ from the original COOL measure as regards point-of-
production information.
7.402. For instance, consumers responding to the KSU Consumer Valuation study had to choose
between three distinct labels: "Product of United States", "Product of Canada, Mexico and US", and
"Product of North America". None of the three la bels makes any reference to the animal's country
of birth, raising, and slaughter. Similarly, the su rvey on demand for shrimp that Mexico submits is
not concerned with labels containing information on the country of birth, raising, and
slaughter/harvest information.916
7.403. Likewise, the KSU Revealed Demand study relies on grocery-store sales data collected
from 2007 until 2011, that is to say two years be fore and after the entry into force of the
2009 Final Rule.917 A s t h e s t a g n a t i o n i n d e m a n d o b s e r v e d b y t h e s t u d y i s r e l e v a n t o n l y t o t h e
period of time when the original COOL measure was in force, it does not show how demand might
be impacted by information on the animal's country of birth, raising, and slaughter.

7.404. The United States submits various pieces of evidence pertaining specifically to consumer
interest in information on the animal's place of birth, raising, and slaughter. 918 S o m e o f t h e
United States' relevant exhibits had been submitted in the original dispute. 919 Most are letters of
support from individual consumers and consumer groups and organizations, as well as comments
on the legislative proposal for country of origin labelling. 920 In this regard, we recall that the
original panel had "cast doubt" on the probative value of this evidence, as noted and relied upon
by the Appellate Body.
921
7.405. The United States also submits a press release from an association of consumer
organizations reporting the results of a telephone survey undertaken in 2013. 922 Two questions in
the survey enquired about 1000 US individuals' interest in country of origin labels showing the
animal's country(ies) of birth, raising, and slau ghter. The press release concludes that "a large
majority of Americans continue to strongly support mandatory country of origin labeling for fresh
meat and strongly favor requiring meat to be labeled with even more specific information about
where the animals were born, raised and processed."
923 Conversely, Mexico points out that this
press release was issued right before the finalization of the amended COOL measure, and argues
that the survey was commissioned and designed to support the trade association's political
position.924
7.406. We note that the press release makes extensive reference to the USDA's regulatory
process leading towards the finalization of the am ended COOL measure. Further, the press release
explicitly references a letter addressed to the USDA in support of its proposed regulatory changes
following the original dispute.
7.407. We recall the Appellate Body's above-mentioned caution with respect to the relevance of
letters and polls submitted in the original COOL legislative process. The press release submitted by
the United States may similarly be regarded with caution insofar as it may be connected to a
particular interest expressed in the regulatory process leading to the adoption of the amended
COOL measure. On balance, we read this press release and its survey as showing that there is
some consumer interest in country of origin information according to point-of-production.
However, we are unable to find this press release and survey dispositive of the actual degree of
consumer interest in such information.
7.6.4.3 Consumers' willingness to pay
7.6.4.3.1 Consumers' willingness to pay for general country of origin information
7.408. The complainants claim that the evidence they submit in relation to risks of non-fulfilment
demonstrates not only consumers' lack of interest in origin information, but also that consumers
are not willing to pay to obtain the information.
925
7.409. The complainants submit one piece of ev idence that addresses consumer willingness to
pay for country of origin information in general. Based on the KSU Consumer Valuation study 926,
the complainants argue that consumers' unwillingness to pay for country of origin information is
revealed by US consumers valuing products labelled "Product of North America" approximately the
same as those labelled "Product of United States".927

7.410. The KSU Consumer Valuation study conclude s that consumers would be willing to pay on
average a premium of USD 1.77 per 12 ounces of meat products for the label "Product of
United States", and USD 1.88 per 12 ounces of meat products for the label "Product of North
America".
928 Despite the higher premium for the North American label, we read this as showing
that consumers are indeed willing to pay something for origin information – whether country-
specific or not. At the same time, the KSU Consumer Valuation study indicates that consumer
willingness to pay has not increased. In the words of the KSU Consumer Valuation study,
"[t]he magnitudes of these [willingness to pay] values are similar to, or less than, those identified
in previous studies" prepared in 2007 and 2009.
929
7.411. The United States submits an Australian report on country of origin labelling that presents
the results of a literature review, including on US consumers' willingness to pay for country of
origin labelling.930 According to the United States, the studies presented in this literature review
demonstrate that US consumers are willing to pay a premium for country of origin labelling.931
7.412. We note that some of the studies presented in the Australian report are the same as those
that were discussed in an academic paper submitted in the original dispute with regard to
consumer willingness to pay. 932 In the original dispute, based on the original panel's findings, the
Appellate Body held that "most US consumers are not prepared to pay to receive information on
origin as defined in the [original] COOL measure with respect to the meat products they
purchase."933 Also, as the Australian report acknowledges, estimating consumer willingness to pay
is "arduous" because origin is a complex attribute and estimates can be influenced by
experimental or study design factors.
934 Accordingly, we are similarly doubtful of the probative
value of the Australian report submitted by the United States in regard to consumers' willingness
to pay.
7.6.4.3.2 Consumers' willingness to pay for point-of-production origin information
7.413. The parties' limited evidence concerning willingness to pay does not address consumers'
willingness to pay for origin information specifically according to point-of-production information.
7.414. As noted, the KSU Consumer Valuation study examines consumers' willingness to pay for
meat carrying labels without any point-of-production origin information. The Australian report
submitted by the United States is a literature review, which does not explain in detail the
methodologies of the referenced studies. From what can be deduced from the review, relevant
studies asked consumers about the premium, if any, they would be willing to pay for labels such as
"Certified U.S." and "U.S.A. Guaranteed".
935 Again, these labels do not convey point-of-production
information.
7.6.4.4 Conclusions on risks of non-fulfilment of the amended COOL measure's objective
7.415. In the original dispute, the Appellate Bo dy addressed the risk of non-fulfilment of the
original COOL measure's objective, concluding that "[o]verall, … the [original p]anel's factual
findings suggest that … the consequences that may arise from non-fulfilment of the objective
would not be particularly grave."
936 The Appellate Body reached this conclusion in light of the
original panel's doubts about on the probative value of evidence presented to show consumer
interest and US consumers' unwillingness to bear all the costs of country of origin labelling of beef
and pork.937

7.416. We recall that, similarly to the original panel, we have found that consumers are not ready
to bear all the costs of the amended COOL measur e. However, unlike the original panel, we have
found in this compliance dispute that consumers are interested both in country of origin
information in general and in country of origin information according to point-of-production.
We have also found that consumers show some willingness to pay for general country of origin
information. At the same time, we have not been given probative evidence showing consumer
willingness to pay for country of origin information according to point-of-production.
7.417. Accordingly, we find that there is some risk associated with the non-fulfilment of the
amended COOL measure's legitimate objective. In terms of the nature of this risk, we observe that
the risk is related to the objective of the amen ded COOL measure, which is to provide consumer
information on origin. The consequence that would arise from non-fulfilment of the amended COOL
measure's objective is that consumers would not receive meaningful information on the origin of
the covered products. In other words, consum ers would be misinformed, confused, or not
informed at all.
7.418. As regards the gravity of this specific consequence, we consider consumer demand for
origin information as a relevant indicator. In this regard, we recall that the evidence on the record
does not allow us to determine the strength of consumer interest in either general country of
origin information or country of origin information according to point-of-production.
As for willingness to pay, the KSU Consumer Valuation study addresses the premium consumers
would be ready to pay for labels showing general information on country of origin. However, as
noted, this study does not show any increase in consumer willingness to pay for country of origin
information from previous studies pre-dating the original COOL measure.
938 Further, while the
study quantifies the premium consumers would be willing to pay for labels showing general
information on country of origin, neither the study nor the complainants have translated the
implications of this figure for the specific degree of gravity of the consequences of not fulfilling the
objective to provide consumer information.
7.419. The benefits accruing to consumers from receiving origin information may also be
determinant of consumer demand for such inform ation. By the same logic, the benefits that
consumers would forego in the absence of meaningful origin information are relevant for the
gravity of the consequences of such an eventuality.
7.420. The USDA attempted to evaluate the "economic benefits" of the original and amended
COOL measures. For the original COOL measure, the USDA concluded that "the economic benefits
will be small and will accrue mainly to those consumers who desire country of origin
information."
939 The USDA added that "[t]he expected be nefits from implementation of th[e 2009
Final R]ule are difficult to quantify." 940 The USDA reached similar conclusions for the
2013 Final Rule by stating that "the expected benefits from implementing mandatory COOL
requirements remain difficult to quantify and that the incremental economic benefits of this final
rule will be comparatively small relative to th ose afforded by the current COOL requirements."
941
Thus, even the USDA was unable to ascertain the benefits to consumers based on their "desire
[for] country of origin information."
942
7.421. The original panel "acknowledge[d] that Members have certain policy space in determining
their objectives":
There are … circumstances in which Members may decide to adopt particular
regulations even in the absence of a specific demand from their citizens, and may do
so without in fact shaping consumer expectations through regulatory intervention.
We also note the panel's statement in Korea – Various Measures on Beef that "there
can be good reasons – apart from any protectionist motives – why a WTO Member

might want information to be provided as to the origin of products, and particularly
meat products, at the retail level".943
7.422. A Member's interest in pursuing a legitimate objective might also be relevant for
ascertaining the gravity of the consequences of not fulfilling such objective. However, even the
USDA found it difficult to quantify the continued "small" consumer benefits under both the original
and amended COOL measures.
7.423. Accordingly, although we have found that the amended COOL measure pursues the same
legitimate objective as the original COOL measure, based on the evidence before us in this
compliance dispute we cannot ascertain the gravity of not fulfilling the amended COOL measure's
objective.
7.424. We have established the nature of the risks, and the consequences, of not fulfilling the
amended COOL measure's objective; however, we have been unable to ascertain the gravity of
these consequences. Accordingly, we conclude our relational analysis of the amended COOL
measure without drawing definitive conclusions on the complainants' Article 2.2 claims.
7.425. We turn to the comparison with the complainants' proposed alternative measures.
944
7.6.5 Comparative analysis
7.426. The complainants refer to four alternat ive measures to demonstrate that the amended
COOL measure violates Article 2.2 of the TBT Agreement:
a. mandatory labelling of muscle cuts based on the country of substantial transformation
(i.e. slaughter), combined with voluntary la belling based on the country of birth and
raising, and the elimination of the amended COOL measure's three main exemptions;
b. extending the mandatory 60-day inventory rule applicable to ground meat also to
muscle cuts, combined with the elimination of the three main exemptions;
c. mandatory labelling using a trace-back system; and
d. mandatory state or province designation of where the three production steps took place,
in addition to the current country designations under the COOL measure.
7.427. As noted above, the Appellate Body held that, for assessing consistency with Article 2.2, in
most cases a comparison of the challenged measure and possible alternative measures should be
undertaken. For such a comparison, "it may be relevant … to consider whether the proposed
alternative is less trade restrictive, whether it would make an equivalent contribution to the
relevant legitimate objective, taking account of the risks non-fulfilment would create, and whether
it is reasonably available".
945
7.428. In attempting to complete its Article 2.2 analysis in the original dispute, the Appellate Body
identified the "relevant" "factual elements" in the context of an "analysis of the proposed
alternative measures": (i) whether these alternative measures are less trade restrictive than the
COOL measure; (ii) whether they would make an equivalent contribution to the relevant objective,
taking account of the risks non-fulfilment would create; and (iii) whether they are reasonably
available to the United States.

7.6.5.1 Preliminary issues
7.429. Before reviewing the complainants' suggested alternatives, we address three preliminary
issues:
a. burden of proof;
b. the United States' argument that any relevant alternative needs to be "significantly" less
trade restrictive than the amended COOL measure; and
c. the compliance cost that any non-discriminato ry alternative would need to exceed in
order to be trade restrictive.
7.6.5.1.1 Burden of proof
7.430. The complainants argue that the burden of proof in the context of comparing alternatives
is limited in two ways. According to Canada, "while ascertaining the level of trade-restrictiveness
of a technical regulation as proposed by the Unit ed States would be possible for regulations that
have been in force long enough to produce documented trade effects, such an ascertainment may
not be done with the same precision for regulations that have not yet produced measurable trade
effects or for possible alternative measures."
947 According to Mexico, in light of the legal test under
Article 2.2, "Mexico's burden is simply to 'identify possible alternatives'"948, and "[t]he burden is on
the United States to present sufficient evidence and arguments showing that these alternative
measures are not less trade restrictive, do not make an equivalent contribution to the objective
pursued, taking account of the risks non-fulfilment would create and are not reasonably
available."
949
7.431. The United States counters that "[n]either approach is consistent with the admonition of
the Appellate Body as to the burden of proof resting on the party that asserts a claim." 950
The United States cites 951 the Appellate Body's statement in US – Wool Shirts and Blouses that
"it is a generally accepted canon of evidence in civil law, common law and, in fact, most
jurisdictions, that the burden of proof rests up on the party, whether complaining or defending,
who asserts the affirmative of a particular claim or defence."952
7.432. Turning to Mexico's argument, we recall that in the original dispute the Appellate Body
summarized "the burden of proof under Article 2.2" as follows:
In order to demonstrate that a technical regulation is inconsistent with Article 2.2,
the complainant must make a prima facie case by presenting evidence and arguments
sufficient to establish that the challenged measure is more trade restrictive than
necessary to achieve the contribution it makes to the legitimate objective, taking
account of the risks non-fulfilment would create. A complainant may, and in most
cases will, also seek to identify a possible alternative measure that is less trade
restrictive, makes an equivalent contribution to the relevant objective, and is
reasonably available. It is then for th e respondent to rebut the complainant's
prima facie case by presenting evidence and arguments showing that the challenged
measure is not more trade restrictive than necessary to achieve the contribution it
makes toward the objective pursued, for example, by demonstrating that the
alternative measure identified by the complainant is not, in fact, "reasonably
available", is not less trade restrictive, or does not make an equivalent contribution to
the achievement of the relevant legitimate objective.

WT/DS384/RW • WT/DS386/RW

7.433. Mexico contends that the Appellate Body's use of the term "identify" for what is required of
complainants in terms of possible alternative measures need not go further than "identification"
in terms of proposing such alternatives. We do not agree with Mexico's reading of the
Appellate Body's explanation. The statement reli ed upon by Mexico includes three elements
relevant for the comparison of the alternatives with the challenged measure, namely "a possible
alternative measure that is less trade restrictive, [that] makes an equivalent contribution to the
relevant objective, and is reasonably available."
954 After placing the burden in regard to these
three factors on the complainants, the Appellate Body moves to discuss the respondent's burden of
proof in respect of alternative measures.
7.434. In our view, Mexico misreads the Appellate Body's statements to suggest that the burden
of proof shifts after the complainant has merely "identified" an alternative, without having to make
at least a prima facie case that such alternative "is less trade restrictive, makes an equivalent
contribution to the relevant objective, and is reasonably available."955 Such an approach would run
counter complainants' burden of proof in WTO disputes enunciated by the Appellate Body in US –
Wool Shirts and Blouses and followed consistently by panels and the Appellate Body since then.
H a d t h e A p p e l l a t e B o d y i n t e n d e d t o p r e s c r i b e a d i f f e r e n t b u r d e n o f p r o o f f r o m t h a t f o l l o w e d i n
general in WTO dispute settlement, we are confident it would have explained that it was doing so.
It did not.
7.435. The Appellate Body's review of the original panel's analysis of legitimate objectives also
suggests that the general rule on burden of proof applies to Article 2.2 of the TBT Agreement.
The Appellate Body was "troubled by certain aspe cts of the [original p]anel's analysis of the
legitimacy of the United States' objective", namely that "although the Panel recognized, at the
outset of its analysis, that the burden of proving that an objective is not legitimate lay with the
complainants, its reasoning at times suggests that it, instead, placed on the United States the
burden of proving that its objective was legitimate."
956
7.436. Further, in the original dispute, the United States argued "that the Panel erred by relieving
the complaining parties of their burden to prove that the measure is 'more trade-restrictive than
necessary' based on the availability of less trade-restrictive alternative measures." 957 In response,
the Appellate Body referenced the above approach to burden of proof under Article 2.2, and
explicitly stated that "the burden of proof with respect to such alternative measures is on the
complainants.958"959
7.437. For these reasons, we reject Mexico's argument with regard to the burden of proof under
Article 2.2. The complainants have the burden to "identify a possible alternative measure that is
less trade restrictive, makes an equivalent contribution to the relevant objective, and is reasonably
available."
960 This requires that the complainants both identify at least one specific alternative
measure, and that they make a prima facie case that such alternative is less trade restrictive,
makes an equivalent contribution to the relevant objective, and is reasonably available.
7.438. These conclusions are also relevant for Canada's point that ascertaining the level of trade-
restrictiveness of a technical regulation "may not be done with the same precision for regulations
that have not yet produced measurable trade effects or for possible alternative measures."
961
We recall that trade-restrictiveness relates to detrimental impact on the competitive opportunities
for imported livestock, and is not limited to actual trade effects. 962 In any event, the complainants
must address the trade-restrictiveness of both the amended COOL measure and the alternative
measures with a sufficient level of precision that allows us to conduct a meaningful comparison
with alternative measures under Article 2.2 of the TBT Agreement. The complainants cannot be
relieved of their burden to prove that at least on e specific, reasonably available, and less trade-

restrictive alternative exists that would fulfil the US objective at least to a degree equivalent to the
amended COOL measure.
7.6.5.1.2 "Significantly" less trade restrictive
7.439. Like in the original dispute
963, the United States argues that a complainant cannot
establish a breach of Article 2.2 if an alternative measure is only insignificantly less trade
restrictive than the challenged measure. The United States argues that the word "significantly" in
footnote 3 to Article 5.6 of the SPS Agreement shou ld guide the interpretation of Article 2.2 of the
TBT Agreement. The United States relies on a letter sent by Mr. Sutherland, then Director-General
of the GATT, to the Chief US Negotiator in mid-December 1993, as a supplementary means of
interpretation of the term "more trade-restrictive than necessary" within the meaning of Article 32
of the Vienna Convention on the Law of Treaties.
964
7.440. Mexico counters that, "[a]s in the original proceedings, the United States attempts to
incorporate Article 5.6 of the SPS Agreemen t into Article 2.2 of the TBT Agreement." 965
Mexico points out that the United States' similar arguments failed in the original proceedings. 966
Mexico refers to the Appellate Body's articulation in the original dispute of the Article 2.2 legal test
enunciated in US – Tuna II (Mexico) , and notes that the Appellate Body refrained from using the
word "significantly", and stated merely that the relevant element of the legal test was
"whether the proposed alternative is less trade restrictive". 967 Mexico adds that Article 2.2 neither
contains the word "significant", nor a footnote similar to footnote 3 to Article 5.6 968,
which provides that "[f]or purposes of paragraph 6 of Article 5 [of the SPS Agreement], a measure
is not more trade-restrictive than required unless there is another measure, reasonably available
taking onto account technical and economic feasibility, that achieves the appropriate level of
sanitary or phytosanitary protection and is significantly less restrictive to trade."
969 According to
Mexico, "[t]hese omissions must be given meaning.970"971
7.441. Mexico adds that according to Article 1.4 of the SPS Agreement, "[n]othing in
this Agreement shall affect the rights of Members under the Agreement on Technical Barriers to
Trade with respect to measures not within the scope of this Agreement". Mexico concludes that
"the SPS Agreement and the TBT Agreement provide different regimes and rules and their scope of
application is mutually exclusive"
972, and it suggests that "precedents interpreting the
SPS Agreement should not be applied in disputes involving the TBT Agreement." 973 Finally, Mexico
argues that the Sutherland letter is irrelevant and cannot be considered a supplementary means of
interpreting Article 2.2 because there is no footnote in that Article, as there is in Article 5.6 of the
SPS Agreement, that clarifies the meaning of the phrase "more trade-restrictive than necessary."
7.442. As Mexico points out, the United States made a very similar argument before the
Appellate Body, including a reference to the Sutherland letter as a supplementary means of
interpretation.974 In particular, the United States argued that the comparison with alternatives
involves assessing the following three elements: "whether (i) there is a reasonably available
alternative measure (ii) that fulfils the Member's legitimate objective at the level that the Member
considers appropriate and (iii) is significantly less trade restrictive."975
7.443. To recall, before the Appellate Body, bo th complainants contested the United States'
similar argument in the context of "more trade-restrictive than necessary". Canada contended that

"the fact that Article 2.2 of the TBT Agreement does not contain a footnote similar to footnote 3 of
the SPS Agreement indicates that 'significantly' shou ld not be read into the 'less trade-restrictive'
test of Article 2.2."976 Mexico advanced arguments similar to the ones adduced in these compliance
proceedings.977
7.444. In reviewing the United States' argument in the original proceedings, the Appellate Body
noted that it had established the "proper approach" for interpreting Article 2.2 of the
TBT Agreement in US – Tuna II (Mexico) .
978 The Appellate Body added that "[t]hrough …
[a comparison of the challenged measure and possible alternative measures] a panel will be able
to judge the 'necessity' of the trade-restrictivene ss of the measure at issue, that is, to discern
whether the technical regulation at issue restricts international trade beyond what is necessary to
achieve the degree of contribution that it makes to the achievement of a legitimate objective."
979
As with the degree of contribution achieved by the challenged measure 980, the Appellate Body did
not qualify this test of relative trade-restrictiveness.
7.445. In describing the comparative analysis for completing its Article 2.2 analysis,
the Appellate Body twice referred to trade-restrictiveness without mentioning the word
"significantly" or referencing Article 5.6 of the SPS Agreement: "it will be relevant to consider
whether the proposed alternative is less trade restrictive"
981 and "whether these alternative
measures are less trade restrictive than the COOL measure." 982 Accordingly, we are of the view
that the Appellate Body's assessment of the four alternative measures in the original proceedings
did not entail an analysis of trade-restrictiveness based on the qualifier "significantly".
7.446. As Mexico points out, Article 2.2 does not contain a footnote similar to that in Article 5.6,
and this should be given meaning. 983 The plain reading of Article 2.2 and the application of the
general rules of treaty interpretation codified in Article 31 of the Vienna Convention on the Law of
Treaties do not warrant introducing a minimum threshold of trade-restrictiveness by importing the
word "significantly" from another covered agreement. Indeed, applying these rules suggests that
the drafters intended that "more trade-restrictiv e than necessary" be interpreted differently in
Article 2.2 than in Article 5.6.
7.447. The Appellate Body has confirmed that th e supplementary means of treaty interpretation
codified in Article 32 of the Vienna Convention have also attained the status of a rule of
"customary or general international law".
984 By the terms of Article 32 itself, recourse to
supplementary means of interpretation is availa ble to "confirm the meaning resulting from the
application of Article 31, or to determine the meaning when the interpretation according to
Article 31: (a) leaves the meaning ambiguous or obscure; or (b) leads to a result which is
manifestly absurd or unreasonable." It does not appear to us that general rules of interpretation
leave the meaning of the term "more trade-restri ctive than necessary" as used in Article 2.2
ambiguous, obscure, or manifestly absurd or unreasonable. Thus, we are not persuaded that
recourse to Article 32 of the Vienna Convention is required in seeking to clarify the meaning of
"more trade-restrictive than necessary" as that term is used in Article 2.2.
7.448. Turning to the Sutherland letter, this states that "it was clear from … consultations at the
expert level that participants felt that the [TBT] Agreement does not concern itself with

976 Appellate Body Reports, US – COOL, para. 77 (footnote omitted).
977 "Mexico contests the need to employ supplementary means of interpretation given that the text of
Article 2.2 and the application of Article 31 of the Vienna Convention make clear that, unlike in Article 5.6 of
the SPS Agreement, in Article 2.2 of the TBT Agreement, there is no footnote providing clarification on the
meaning of the phrase 'more trade-restrictive than necessary'. The absence of such a footnote must have
meaning. Indeed, even the letter relied upon by the United States indicates that it was not the common
intention of Members to incorporate such a footnote in the TBT Agreement. Therefore, in Mexico's view, there
is no legal basis for incorporating into Article 2.2 of the TBT Agreement the test in footnote 3 to Article 5.6 of
the SPS Agreement." Appellate Body Reports, US – COOL, para. 109.

insignificant trade effects."985 In the light of this, the Sutherland letter asked the United States to
withdraw its objection to adopting the TBT Agreement without the United States' proposed
footnote to Article 2.2 (similar to footnote 3 to Article 5.6 of the SPS Agreement).
986
The Sutherland letter notes that "[i]t was not possible to achieve the necessary level of support for
the U.S. proposal to add a new footnote to Article 2.2 … ." 987
7.449. To us, the Sutherland letter does not se rve the purpose suggested by the United States.
Rather, it supports the view that there was no ag reement among negotiators to read the footnote
to Article 5.6 of the SPS Agreement into the TBT Agreement. Thus, we cannot agree with the
United States that we should read such language into the text of Article 2.2.
7.450. According to the Sutherland letter, what negotiators seemed to agree on is that the
TBT Agreement does not concern itself with "insignificant trade effects." 988 The Sutherland letter
does not define this term, let alone suggest that this should be applied specifically to the
comparison of the trade-restrictiveness of a challenged measure with alternatives. 989 Instead, the
Sutherland letter references the fifth recital of the preamble of the TBT Agreement, which refers to
ensuring that technical regulations do not create unnecessary obstacles to international trade.
Thus, even if it were appropriate in this case to rely upon supplementary means of interpretation
under Article 32 of the Vienna Convention – and we are not convinced that it is – what the
Sutherland letter might demonstrate is negotiators' agreement on the overall balance of the
TBT Agreement, as reflected in the fifth preambular recital. This is markedly different from what
the United States sees in the Sutherland letter.
7.451. We therefore decline to read the word "significantly" into Article 2.2 of the TBT Agreement.
7.6.5.1.3 Sumner Economic Analysis on the magnitude of compliance costs
7.452. Canada submitted an economic study by Pr ofessor Sumner to support its estimate of the
magnitude of added compliance costs required for any non-discriminatory alternative measure to
cause export revenue losses equivalent to those caused by the original COOL measure (Sumner
Economic Analysis).
990 Canada claims that the Sumner Economic Analysis demonstrates that any
non-discriminatory alternative measure 991 would require "incredibly large" costs in order to drive
down imports as much as the original COOL measure has done.992
7.453. Following standard supply and demand assumptions 993, the model specification of the
added compliance costs in the Sumner Economic Analysis hinges on four parameters: (i) the
elasticity of demand for meat; (ii) the elasticity of livestock supply; (iii) the share of livestock cost
in the meat product's retail unit cost; and (iv) the change in livestock revenue based on the
econometric estimations of the original COOL measure's impact in the Sumner Econometric
Study.
994
7.454. According to Canada, depending on these parameters' values, the findings of the Sumner
Economic Analysis, when applied to the US-Canada livestock market, suggest that any alternative
measure would have to generate a 27-118% increase in meat unit in the cattle sector, and a
22-72% increase in the hogs sector, to cause export revenue losses comparable to the impact of

the original COOL measure.995 For an average-sized (1,280 pound) steer, the additional processing
and marketing costs due to increased costs under any non-discriminatory alternative measure
would need to range between $608 and $2,672. For an average-sized (280 pound) hog, the
additional processing and marketing costs would need to range from $116 to $378.
996 Referring to
the estimated costs of Uruguay's trace-back system 997, Canada argues that the findings of the
Sumner Economic Analysis demonstrate that a non-discriminatory alternative measure such as a
trace-back system could not plausibly cause grea ter export revenue losses than those caused by
the original or the amended COOL measure.
998
7.455. In response to the Panel, Mexico submi tted a variant of the Sumner Economic Analysis
adapted to the US-Mexican livestock market. 999 Using the same economic model specification as
Canada, the Mexican variant of the Sumner Economic Analysis suggests that, depending on the
values of the parameters chosen 1000, any non-discriminatory alternative measure would have to
entail a 6-30% increase in the unit cost of meat in the US-Mexican cattle sector. For an average-
sized (770 pound) Mexican feeder cattle, an alternative measure such as a trace-back system
would have to add from $136 to $679 per head of cattle to existing costs in order to generate an
impact on Mexico's cattle export revenues losses equivalent to the impact of the original COOL
measure.
1001 Mexico argues that since the Sumner Economic Analysis only focuses on the original
COOL measure, the results understate the additional costs that would have to be created to match
the larger adverse trade effects of the amended COOL measure.1002
7.456. The United States disagrees with Canada and Mexico, and argues that the methodology
and theoretical economic model of the Sumner Economic Analysis and its Mexican variant are
flawed. According to the United States, the measure of lost export revenue, unlike the common
approach of price-gap analysis, is an unusual approach in economics that requires a sophisticated
economic modelling, the results of which are sensitive to the underlying assumptions.
1003
The United States contends that some of the assumptions in the Sumner Economic Analysis
contradict several academic papers. 1004 In particular, the United States questions the use of a
single country-market, in which (i) there is no substitutability effects between meat (beef, pork
and chicken); and (ii) the Canadian or Mexican export supply sectors respond in the same way as
the US domestic supply sector. The United States argues that since the measure of lost export
revenue is sensitive to large price elasticities, a small change in conditions can lead to major
changes in imports and exports values.
1005 The United States also claims that there is no basis for
equating the term "export revenue loss" with "cos ts" to assess whether an alternative measure is
less trade restrictive1006 than the amended COOL measure.1007

1005 The United States suggests measuring the loss of total profits to producers, defined as the
"producer surplus" loss, because, according to the United States, the measure of export revenue losses
overstates the gross profit losses of livestock producers by overlooking the reduced production costs associated
with reduced production. United States' comments on Canada's additional response to Panel question H,
para. 14.
1006 According to the United States, the Sumner Economic Analysis also relies on a definition of
"non-discrimination" that contradicts the Appellate Body's finding defining a non-discriminatory measure as a
WT/DS384/RW • WT/DS386/RW

7.457. In addition to the alleged incorrect mode l specification of the Sumner Economic Analysis
and its Mexican variant, the United States argues that the estimations suffer from numerous data
and methodological shortcomings. 1008 The United States claims that the use of inflated
econometric estimates in the Sumner Economic Analysis applied to Canadian livestock yields
drastically overstated additional costs. 1009 The United States further points out that the Mexican
variant of the Sumner Economic Analysis did not rely on econometric estimates but used a "COOL
discount" of $40 per head to estimate the change in Mexican cattle export revenue caused by the
original COOL measure, which, according to the United States, is inconsistent with Canada's effort
to isolate the COOL effect from other factors.1010
7.458. Overall, the United States claims that the findings of the Sumner Economic Analysis and its
Mexican variant are inflated, unrealistic and not borne out by the facts and data in the market.
According to the United States, Mexican exports to the US and Canadian cattle prices relative to
US price have both increased since the implementation of the original COOL measure.
The United States further argues that the results contradict basic economics referenced in various
papers by Professor Sumner. According to these papers, taxing trade in livestock (i.e. a "COOL
discount") in an open and duty-free meat market would have minimal effect on the price of
livestock. It could only affect where the live stock are slaughtered, leaving the supply of, or
demand for, meat unaffected.
1011
7.459. More generally, the United States claims that the Sumner Economic Analysis and its
Mexican variant are irrelevant because they do not identify any particular alternative measure, but
rather assess the trade effect of an undefined measure unrelated to country of origin labelling.
1012
As a result, the United States contends that both Canada and Mexico fail to establish (i) how the
figures in Canada's Sumner Economic Analysis and its Mexican variant correlate to a reduction in
Canadian and Mexican exports; (ii) what the corresponding costs would be under a trace-back
regime; (iii) how the additional costs of the alternative measure would not exceed the estimated
minimum trade-restrictive cost; and (iv) how such additional costs would relate to an increase in
trade under such an alternative.
1013 The United States is of the view that any trade impacts the
amended COOL measure may cause are due to the much lower processing and marketing costs of
the original and amended COOL measures outlined in the USDA regulatory impact analyses that
accompany the 2009 and 2013 Final Rules. Moreover, th e United States contends, these costs will
fall over time after industry has adjusted to the new labelling regime of the amended COOL
measure.

7.460. As noted1015, we consider that it is not our task to establish a unified economic model;
rather, we need to assess, in light of the parties' arguments, whether the simulated estimations
are reliable.
7.461. We note that, unlike a general equilibriu m model, a partial equilibrium analysis, such as
the Sumner Economic Analysis, only considers the effects of a policy in the equilibrium of a
particular market, i.e. the US-Canada and US-Mexico market segments, respectively, ignoring its
effects (including feedback effects) in any other markets.
7.462. Having reviewed the Sumner Economic Analysis and its Mexican variant, we note that the
simulation results are contingent on the interplay of three main elements:
a. the theoretical model used to derive the effects of the original COOL measure on market
equilibrium, which depends on the assumptions considered, many of which are simplified
in order to derive readily a closed-form (solvable) specification;
b. the value of the exogenous parameters of the demand and supply elasticities and of the
share of slaughter livestock farm price in cost of retail meat; and
c. the estimation of the lost imported livestock revenue caused by the original COOL
measure, which hinges on the pre-COOL and post-COOL price and quantity data used for
the calibration and on the estimation of the long-run impact of the original COOL
measure.
1016
7.463. The comparison of the figures reported in the Sumner Economic Analysis and its Mexican
variant shows how sensitive the results are to the set of parameters' value considered, especially
with respect to the value assigned to the change in export revenue. The simulated increase in the
unit cost of meat can be up to 337%, 227% and 400% higher than the lowest simulated figures
for the Canadian cattle and hogs, and Mexican cattle sectors, respectively.
7.464. Moreover, as the United States points out, all economic models are based on assumptions,
and small changes in these assumptions can have major (positive or negative) effects on the
simulated figures. We also note that Canada and Mexico fail to address some of the issues raised
by the United States, such as the existence of el asticities of substitution between different meats
and the use of specific and different supply elasticities for Canada, Mexico and the United States.
For instance, various studies assessing US and Canadian supply and import demand elasticities
suggest that the short-run US import demand price elasticity for Canadian slaughter steers (-1.79)
is relatively elastic compared to the US slaughter demand price elasticity (-0.65 and -0.76), mainly
because of Canada's small market share of US cattle supplies.
1017
7.465. We note further that we have not been gi ven simulation results associated with different
assumptions underlying the economic model specification (and not simply with different
parameters values), we are unable to determine an d compare to what extent the findings of the
Sumner Economic Analysis and its Mexican variant would have changed if some of the above-
referenced points raised by the United States
1018 were to be incorporated in the computation of the
model specification. As a result, we cannot rely on the range of estimated figures of the Sumner
Economic Analysis and its Mexican variant.
7.466. In addition, as the United States points out, the figures reported in the Sumner Economic
Analysis and its Mexican variant are related to a hypothetical non-discriminatory undefined
measure. In fact, the structure of the economic model specification in the Sumner Economic
Analysis is such that it makes no distinction between alternative measures. The Sumner Economic
Analysis and its Mexican variant implicitly assume, without substantiating it, that the set of all
possible hypothetical non-discriminatory measures has the same impact in terms of added
compliance costs. As a result, neither of the complainants' studies assesses the actual magnitude

of the cost of a specific trace-back system or any of the other three alternatives put forward by the
complainants. Hence, we cannot draw any inferences from these studies as to whether the implied
additional costs of an alternative, such as a tr ace-back system, implemented in the United States
would be effectively lower than the hypothetical and simulated figures.
7.467. Given the limitations of Canada's Sumner Economic Study and its Mexican variant, and our
conclusion that we cannot rely on them in our assessment of alternative measures, we need not
address the United States' procedural objections to Mexico's reliance on the Sumner Economic
Study.
1019
7.6.5.2 First alternative measure
7.468. The complainants' first alternative measure would involve mandatory origin labelling based
on the country of substantial transformation, combined with voluntary point-of-production labelling
according to the country of the animal's birth, raising, and slaughter.
1020 The first alternative
measure would cover all muscle cuts from US-slaughtered animals (Categories A-C) 1021,
and exclude foreign-slaughtered muscle cuts (Category D)1022 and ground meat (Category E).1023
7.469. The mandatory element of the complainants' first alternative measure would require that
Labels A-C indicate origin according to substantial transformation, i.e. the animal's country of
slaughter.
1024 The labelling requirements for muscle cuts from foreign-slaughtered animals
(Label D)1025 would remain unchanged; the first alternative measure would extend these
requirements to muscle cuts from US-slaughtered animals (Labels A-C). 1026 As all Category A-C
muscle cuts originate from US-slaughtered animals, all Labels A-C 1027 could read "'Product of the
U.S.' (or some variant indicating US origin)" 1028, such as "Slaughtered (or harvested) in the
US".1029
7.470. As a voluntary aspect of the complainants' first alternative measure, Labels A-C may
specify the countries where the animal was born and raised 1030, thus providing the same
information as under the amended COOL measure. The first alternative measure would not change
the current Label D in this regard either; rath er, it would extend the amended COOL measure's
voluntary labelling rule for Category D muscle cuts to US-slaughtered (Category A-C) muscle
cuts.1031
7.471. For US-slaughtered muscle cuts, the complainants' first alternative measure would remove
the three exemptions maintained under the amended COOL measure for (i) entities not meeting

allows for providing more detailed origin information for Category D muscle cuts on a voluntarily basis.

steps (i.e., born, raised, and slaughtered) provided records to substantiate the claims are maintained".

the definition of the term "retailer"; (ii) ingredients in "processed food items"; and (iii) products
served in a "food service establishment".1032
7.472. As to how origin information would be conveyed following the removal of these three
exemptions, according to Canada:
[f]ood service establishments could convey information about origin on menus, signs
or placards. Menus and displays could be set up so as to allow a modification in the
information without having to replace them (through clips on menus, for instance).
With respect to processed food items, orig in information on muscle cuts of beef or
pork they contain could be displayed on packages in the list of ingredients
(e.g. "beef (slaughtered in the U.S.)" under the first alternative measure; and
"pork (product of U.S., Canada)" under the second alternative). … [F]ood processors
may not have to modify the ingredients lists often, because it would be relatively easy
for them to find a steady supply of meat with the same origin (e.g. product of the U.S.
and Canada). As for small retailers, they would have to convey information about
origin in the same way as do covered retailers under the amended COOL measure
(e.g. butcher shops could use signage).
1033
7.473. Mexico adds that "[f]ood service establishments could inform consumers about the origin
of muscle cuts and processed food items by indicating origin information on menus, blackboards
where daily specials are posted, and on their web sites".1034
7.6.5.2.1 Whether the first alternative meas ure would make an equivalent contribution
to the relevant legitimate objective
7.474. In meat production "substantial transf ormation" means the slaughter of the originating
animal – both in the context of the amended CO OL measure and the complainants' suggested first
alternative measure.1035 Slaughter is only one of the three production steps (birth, raising, and
slaughter) on which Labels A-C provide consumer information under the amended COOL measure.
Thus, the complainants' first alternative measure would mandate less label information on the
origin of muscle cuts derived from US-slaughter ed livestock than the amended COOL measure.
As the Appellate Body held, "under … a [mandatory] labelling scheme [based on substantial
transformation,] consumers would be provided with information on where livestock were
slaughtered, but they would not be provided with any information as to where the livestock were
born and raised."
1036
7.475. This would result in limited contribution to the objective of providing origin information to
consumers. In the original dispute, the Appellate Body noted that, "in the context of Article 2.4 of
the TBT Agreement, the [original p]anel [had] found that CODEX STAN 1-1985, which is based on
the principle of substantial transformation, 'does not have the function or capacity of
accomplishing the objective of providing information to consumers about the countries in which an
animal was born, raised and slaughtered' and hence is ' ineffective and inappropriate for the
fulfilment of the specific objective as defined by the United States'."
1037 According to the
Appellate Body, these findings by the original panel "suggest that a mandatory labelling regime
based on substantial transformation would, at best, contribute only partially to the objective of
providing information to consumers on where livestock from which meat is derived were born,
raised, and slaughtered."

United States applies a "substantial transformation" test and, for NAFTA countries, a test based on change in
tariff classification to determine origin. According to the complainants, the result under both tests is to
designate the place of slaughter as the country of origin. Canada's first written submission, para. 18 and

WT/DS384/RW • WT/DS386/RW

7.476. The complainants explain that information on the other two production steps (birth and
raising) would be voluntary under their first alternative measure. 1039 According to the
Appellate Body, "the contribution of a voluntary labelling requirement to the objective of providing
consumers with information on where livestock were born, raised, and slaughtered would be a
function of the accuracy with which labels reflect origin as the country or countries in which
different production steps took place, the scope of the products covered by such a voluntary
labelling scheme, and the extent to which labels would be used."
1040
7.477. In the original dispute, the Appellate Body explained that "in its analysis under Article 2.1
of the TBT Agreement, the [original p]anel [h ad] referred to evidence suggesting that US
consumers are not generally willing to pay for information on origin, and that, prior to the
introduction of the COOL measure, there was a lack of widespread participation in voluntary origin
labelling programmes."
1041 We have held that the original panel's finding about "the lack of
[consumer] interest in a voluntary COOL regime" 1042 continues to apply in this compliance
dispute.1043
7.478. In the context of the first alternative measure, Canada and the United States question
whether industry participants would voluntarily provide origin information in the absence of
sufficient consumer readiness to pay for it.
1044 Mexico argues that "at least one major retailer"
voluntarily labelled its products "100% US beef". 1045 Although Mexico advances this piece of
evidence1046 to show the occurrence of voluntary origin labelling, it is silent on the extent of such
voluntary labelling and whether industry participants would voluntarily affix country of origin labels
on muscle cuts according to the three production steps. On the whole, the evidence does not
suggest that the voluntary option would be exercised on a wide scale.
7.479. Thus, even with its voluntary element, the complainants' first alternative measure would
provide less information on origin than the amended COOL measure for muscle cuts derived from
US-slaughtered livestock covered by Labels A-C.
7.480. In the original dispute, the Appellate Body reviewed a similar measure with combined
mandatory and voluntary aspects, but could not draw a definitive conclusion for comparing the
respective degrees of contribution after assessing merely the contribution under the alternative
measure's mandatory and voluntary aspects.
1047 The Appellate Body noted that an alternative
measure's coverage might also be relevant for a ssessing its degree of contribution. In reviewing
the complainants' first alternative in the original dispute (mandatory origin labelling based on
substantial transformation), the Appellate Body stated that:
without knowing whether a mandatory labelling system based on substantial
transformation would require all beef and pork sold in the United States to be labelled,
we are unable to compare the degree of the C OOL measure's contribution with that of
this alternative measure proposed by the complainants.1048
7.481. We note that the complainants' first alternative measure would remove the three
exemptions of the amended COOL measure. Given the extent of these exemptions 1049, the first
alternative measure would cover a significantly wider range of muscle cuts from US-slaughtered
livestock than the amended COOL measure. Effectively, all muscle cuts from US-slaughtered

1047 According to the Appellate Body, "it is unclear whether a voluntary labelling scheme combined with
a mandatory labelling requirement based on substantial transformation would make a contribution to the
objective of providing consumers with information on where livestock were born, raised, and slaughtered, at
least equivalent to the contribution made by the COOL measure." Appellate Body Reports, US – COOL,

livestock marketed in the United States would carry an origin label under the complainants' first
alternative measure. At the same time, the labels under the first alternative measure would
provide less origin information for this extended coverage than the amended COOL measure.
The question, therefore, is whether a suggested alternative that would provide less origin
information on a wider range of products would make at least "an equivalent contribution to the
relevant legitimate objective"
1050 as the amended COOL measure.
7.482. We have found that the objective of the amended COOL measure is to provide origin
information to consumers1051, and that this is a legitimate objective under the TBT Agreement. 1052
We have also established the level at which the United States "actually"1053 achieves this legitimate
objective through the amended COOL measure. 1054 Further, the Appellate Body has consistently
held that, for the purposes of Article 2.2 of th e TBT Agreement, an alternative measure needs to
make at least an "equivalent degree" of contribution as the challenged measure. 1055 Hence, an
alternative measure making a less than equivalent contribution to the legitimate objective in
question cannot prove a violation of Article 2.2 of the TBT Agreement.
7.483. The complainants have confirmed that all
1056 Labels A-C could read "Product of the
U.S."1057 or "Slaughtered (or harvested) in the US" 1058 under their first alternative measure. 1059
As a result, not only would the first alternative measure provide less origin information
(although for a significantly wider range of products), it would result in all muscle cuts from US-
slaughtered animals carrying the same label, irrespective of where the animals were born and
raised. This would be in sharp contrast with the amended COOL measure, which mandates distinct
labels for Category A, B, and C muscle cuts, reflecting not only the animals' identical country of
slaughter (i.e. the United States) but also their po tentially different countries of birth and raising.
Based on this, the first alternative measure as described by the complainants does not seem
capable of making an actual contribution to the objective of providing consumer information on
origin at least equivalent to the actual contribution of the amended COOL measure.
7.484. While recognizing that Labels A-C would appear the same under their first alternative
measure, the complainants argue that this alternative measure, taken as a whole and including its
extended coverage, should be considered as making an equivalent contribution "taking account of
the risks non-fulfilment would create". The United States responds that alternative measures that
contribute to a legitimate objective to a lesser degree than the challenged measure cannot prove a
violation of Article 2.2.
1060 Referencing the sixth recital to the TBT Agreement 1061, the

1061 The sixth recital to the TBT Agreement reads as follows: "Recognizing that no country should be
prevented from taking measures necessary to ensure the quality of its exports, or for the protection of human,
animal or plant life or health, of the environment, or for the prevention of deceptive practices, at the levels it
considers appropriate, subject to the requirement that they are not applied in a manner which would constitute
a means of arbitrary or unjustifiable discrimination between countries where the same conditions prevail or a
disguised restriction on international trade, and are otherwise in accordance with the provisions of this
Agreement".

WT/DS384/RW • WT/DS386/RW

7.485. We are mindful of a Member's right to pursue legitimate objectives "at the levels it
considers appropriate." 1063 However, as the Appellate Body noted, the preamble to the
TBT Agreement strikes a "balance … between, on the one hand, the desire to avoid creating
unnecessary obstacles to international trade and, on the other hand, the recognition of Members'
right to regulate."
1064 The sixth preambular recital to the TBT Agreement reflects this by setting
forth that a Member shall not be prevented from taking measures necessary to achieve its
legitimate objectives at the levels it considers appropriate, "subject to certain qualifications"
1065:
namely that such measures "are not applied in a manner which would constitute a means of
arbitrary or unjustifiable discrimination between countries where the same conditions prevail or a
disguised restriction on international trade, and are otherwise in accordance with the provisions of
this Agreement."
7.486. The Appellate Body explained the relevance of the phrase "the risks non-fulfilment would
create" in the context of a comparative analysis under Article 2.2:
[T]he obligation to consider 'the risks non-fulfilment would create' suggests that the
comparison of the challenged measure with a possible alternative measure should be
made in the light of the nature of the risks at issue and the gravity of the
consequences that would arise from non-fulfilment of the legitimate objective.
This suggests a further element of weighing and balancing in the determination of
whether the trade-restrictiveness of a technical regulation is 'necessary' or,
alternatively, whether a possible alternative measure, which is less trade restrictive,
would make an equivalent contribution to the relevant legitimate objective, taking
account of the risks non-fulfilment would create, and would be reasonably
available.
1066
7.487. This suggests that "the risks non-fulfilment would create" may be a relevant factor in
assessing whether an alternative measure fulfils the legitimate objective to an equivalent degree
as the challenged measure. This is confirmed by the Appellate Body's summary of the three main
elements of the comparative analysis under Article 2.2 of the TBT Agreement:
In making this comparison, it will be relevant to consider whether the proposed
alternative is less trade restrictive; whether it would make an equivalent contribution
to the relevant legitimate objective, taking account of the risks non-fulfilment would
create; and whether it is reasonably available.
1067
7.488. Given the potential relevance of risks of non-fulfilment in comparing degrees of
contribution, we consider that providing less origin information to consumers for a significantly
wider range of products through a measure like the complainants' first alternative measure might
achieve an equivalent degree of contribution as the amended COOL measure. However,
in reviewing "the risks non-fulfilment would create", we were unable to ascertain the gravity of
these consequences.
1068 Accordingly, we cannot determine the specific implications of risks of non-
fulfilment for the interplay between less information coupled with more extensive coverage under
the first alternative measure, or for the first alternative's degree of contribution.
7.489. We observe that less origin information might reduce consumer confusion or
misinformation in some circumstances. For example, consumers might find a large amount of
information on a product packaging difficult to und erstand. In addition, consumers might be more
interested in specific types of origin information, for instance in origin information according to
certain production steps, such as the place of sl aughter. In any event, the implications of the
quantity of origin information for consumers be ing effectively informed would depend on the

nature of the information being conveyed and the method of conveyance. In the context of the
first alternative measure, it is difficult to establish the exact implications for consumer information
of having less information on the labels – even for a wider coverage of products.
7.490. Ultimately, the complainants have not persuasively demonstrated how the increased
coverage of their first alternative measure would compensate for less origin information provided
on Labels A-C under the first alternative measure. Accordingly, we find that the complainants have
not made a prima facie case that their first alternative measure would make an at least equivalent
degree of contribution to the objective of providing origin information to consumers as does the
amended COOL measure.
7.491. The United States argues that this should be the end of our analysis of the first alternative
measure.
1069 We agree. According to the Appellate Body, the three factors of the comparative
analysis are conjunctive.1070 An alternative measure that has not been proven to make at least an
equivalent degree of contribution cannot serve as a basis for finding a violation of Article 2.2 of the
TBT Agreement – irrespective of whether the alternative measure is reasonably available or how
its eventual trade-restrictiveness compares with the challenged measure. As the United States
points out
1071, at the outset of its Article 2.2 assessment in US – Tuna II (Mexico) ,
the Appellate Body noted all three factors of the comparative analysis under that Article 1072, but
ended its Article 2.2 review after having overturned the panel's finding that the alternative
measure would make a contribution equivalent to that made by the challenged measure.1073
7.6.5.3 Second alternative measure
7.492. The complainants' second alternative measure would extend ground meat labelling rules to
muscle cuts
1074 from US-slaughtered 1075 animals.1076 Thus, Labels A-C would "list all countries of
origin contained therein or that may be reasonably contained therein". 1077 This would be governed
by the 60-day "inventory allowance" 1078, according to which if "a raw material from a specific
origin is not in a processor's inventory for more than 60 days, that country shall no longer be
included as a possible country of origin."1079
7.493. Under the second alternative measure, Labels A-C would not provide information on where
the originating animal was born, raised, and slaughtered. 1080 These labels would read "Product of
the U.S."1081 for muscle cuts from exclusively US-origin animals. In light of the 60-day inventory
allowance, the labels could also read "Product of the U.S., Canada" 1082 or "Product of the
United States and Mexico"1083 depending on whether Canadian or Mexican origin raw material may
also be reasonably contained in the ground meat. As the original panel held, "a processor may use
the same label for all of its ground meat, provided that the label lists all countries of origin of the

1070 See Appellate Body Reports, US – COOL, para. 376.
1071 United States' opening statement at the meeting of the Panel, para. 38.
1072 The Appellate Body stated that "[i]t was for the Panel, therefore, in assessing Mexico's claim that
the US 'dolphin-safe' labelling provisions 'are more trade-restrictive than necessary' within the meaning of
Article 2.2, to examine, inter alia, the contribution that the US measure makes to the achievement of its
objectives; the trade-restrictiveness of the US 'dolphin-safe' labelling provisions; whether Mexico had identified
a 'reasonably available' and less trade-restrictive alternative measure, and to compare the degree of the US
measure's contribution with that of the alternative measure, which is reasonably available and less trade
restrictive, taking account of the risks non-fulfilment would create." Appellate Body Report, US – Tuna II

meat ground by the processor, and that the processor has had in its inventory meat for grinding of
each origin at least every 60 days."1084
7.494. Similarly to the first alternative measure, the complainants' second alternative measure
would remove the three exemptions of the original COOL measure and maintained by the
amended COOL measure.1085
7.6.5.3.1 Whether the second alternat ive measure would make an equivalent
contribution to the relevant legitimate objective
7.495. The complainants' second alternative measure would extend the original COOL measure's
unchanged ground meat labelling rules, including the 60-day inventory allowance, to muscle cuts
from US-slaughtered animals.
7.496. As noted, under the second alternative measure, Labels A-C would "list all countries of
origin contained therein or that may be reasonably contained therein".
1086 Thus, unlike under the
amended COOL measure, Labels A-C would not provide country of origin information according to
point-of-production (birth, raising, and slaughter).
1087 As a consequence, the complainants' second
alternative measure would involve less detailed origin information for muscle cuts from US-
slaughtered animals than the amended COOL measure.
7.497. Apart from the reduced detail of information, the 60-day inventory allowance would
introduce new potential for label inaccuracy. The original panel viewed inventory allowance as a
"significant flexibility" 1088 because "it allows a processor to reference a country of origin on its
ground meat label even if the processor has not had ground meat from that particular country in
its inventory for the last 60 days or less."
1089 In addition, in its Article 2.2 analysis, the original
panel held that the ground meat label could provide origin information only with limited accuracy:
Because of th[e] so-called "60-day inventory allowance" in the 2009 Final Rule (AMS),
the ground meat label is likely to convey inaccurate origin information as a processor
may use the same label for all of its ground meat listing all countries of origin of the
ground meat that the processor has had in its inventory at least for 60 days. In other
words, an origin label affixed on ground meat could be listing a country name of meat
that the processor might not even have used to produce the specific ground meat in
that package. In fact, the Vilsack letter contains a statement confirming this:
"[t]his [60-day inventory allowance] provision allows for labels to be used in a way
that does not clearly indicate the product's country of origin".
1090
7.498. As regards the actual contribution of th e second alternative measure, like for the first
alternative measure, we take note of the origin information that Category A-C muscle cut labels
would convey based on the complainants' descr iptions. According to Canada, the "majority"
1091 of
US-slaughtered muscle cuts would be labelled "Product of the U.S." 1092, and market actors
handling muscle cuts of both US and Canadian origin would increasingly affix a joint "Product or
the US., Canada" label.
1093 Likewise, according to Mexico, the "majority" 1094 of meat processed by
plants relying also on Mexican cattle would carry a joint "Product of the United States and Mexico"
label.1095

1085 As for how previously exempted products and sectors would label products under the complainants'
second alternative measure, see paras. 7.472-7.473 above.

7.499. We note that these labels would be similar in appearance to those under the original COOL
measure1096, but would indicate origin according to the flexibility for mixing animals and products
of potentially different sources. In light of the 60-day inventory allowance, and given that Mexico
and Canada are the two main sources of US livestock imports
1097, we note the possibility that a
single North American label (e.g. "Product of Canada, Mexico, and the United States") could be
a f f i x e d t o s o m e p r o p o r t i o n o f m u s c l e c u t s f r o m U S - s l a u g h t e r e d a n i m a l s m a r k e t e d i n t h e
United States. As long as products from Canada, Mexico, and the United States are in a market
participant's inventory during any 60-day wind ow, muscle cuts derived from US-slaughtered
animals could indistinguishably carry the same North American label under the complainants'
second alternative measure.
1098 Absent indications from the complainants to the contrary, this
outcome cannot be excluded in light of the relative integration of the North American livestock and
meat market 1099 and the fact that the 60-day inventory allowance is available for market
participants at every stage of meat supply and distribution. 1100 Further, to the extent that market
participants make economically rational choices to avail themselves of this inventory allowance, an
increasing proportion of muscle cuts of purely US origin would no longer be labelled as such under
the second alternative measure, but would carry a label also showing a foreign origin.1101
7.500. The second alternative measure could thus result in muscle cuts from US-slaughtered
animals born or raised in different countries carrying the same label, which could possibly be
affixed on muscle cuts that do not originate in at least one of the countries shown on the label. 1102
This would be in sharp contrast with the amended COOL measure, which mandates distinct labels
for Category A, B, and C muscle cu ts, reflecting – with the relatively higher degree of accuracy
established above
1103 – the countries of birth, raising, an d slaughter of the originating animals.
Thus, the complainants' second alternative measure would potentially provide less accurate origin
information than the amended COOL measure for covered muscle cuts of US-slaughtered animals.
Based on this, the second alternative measure as described by the complainants does not seem
capable of making an actual contribution to the objective of providing consumer information on
origin at least equivalent to the actual contribution of the amended COOL measure.
7.501. Like for the first alternative measure, the complainants argue that removing the three
exemptions of the amended COOL measure should offset the loss of accuracy in origin information
under the second alternative measure.
1104 We have explained 1105 that in light of the risks, we
considered that the first alternative measure might achieve an equivalent degree of contribution as
the amended COOL measure, by providing less origin information to consumers for a significantly
wider range of products. In a similar vein, we consider that by providing less accurate origin
information to consumers for a significantly wider range of products, the second alternative
measure might achieve an equivalent degree of contribution as the amended COOL measure.
In any event, absent sufficient arguments and ev idence from the complainants, we have been
unable to ascertain the gravity of the consequences of not fulfilling the objective of providing
consumer information on origin. 1106 Accordingly, like for the first alternative measure, we cannot
determine the specific implications of risks of non-fulfilment for the interplay between less

1096 See Table 1 above; Panel Reports, US – COOL, para. 7.100.
1097 The trade figures submitted by the parties indicate that Canada and Mexico are the two main direct
sources of US livestock imports. According to these figures, the United States imports cattle from Canada and
Mexico, and hogs from Canada. For US cattle imports, see Exhibit Appendix CDA-2, Exhibits MEX-60, and
Exhibit US-59. For US hog imports, see Exhibit Appendix CDA-7 and Exhibit US-59.
1098 The original panel held that "a processor may use the same label for all of its ground meat, provided
that the label lists all countries of origin of the meat ground by the processor, and that the processor has had
in its inventory meat for grinding of each origin at least every 60 days." Panel Reports, US – COOL,

accurate information and more extensive coverage under the second alternative measure, or for
the second alternative's degree of contribution.
7.502. Like for the first alternative measure, we lack relevant arguments and explanations from
the complainants in this regard. Consequently, we cannot determine how and to what degree
extended coverage could actually compensate for the less accurate origin information provided to
consumers under the second alternative measure.
7.503. Accordingly, we find that the complainants have not made a prima facie case that their
second alternative measure would make an equivalent degree of contribution to the objective of
providing origin information to consumers as the amended COOL measure. In light of this finding
and for the reasons explained under the first alternative measure 1107, we end our analysis of the
second alternative measure here.
7.6.5.4 Third alternative measure
7.504. The complainants' third alternative measure would apply to muscle cuts from
US-slaughtered animals.1108 It would entail a mandatory trace-back 1109 system to provide "specific
information"1110 on "the precise location" 1111 where the animal was born, raised, and
slaughtered.1112 The complainants do not indicate that this alternative would remove the existing
exemptions under the amended COOL measure.
7.505. The essence of the third alternative measure would be to preserve the link between the
animal (or group of animals) and the resulting meat1113 by requiring that a retailer be able to trace
a muscle cut piece of meat back to the original animal.1114 According to the complainants, the third
alternative would eliminate the need to segregate, throughout the supply chain, both animals and
muscle cuts on the basis of the country or countries where the animals were born and raised,
because each individual animal or group of animals and each covered muscle cut commodity would
have to be traceable, regardless of its country of origin.1115
7.506. The United States contends that the comp lainants present the third alternative "more as a
concept than as an actual measure". 1116 As explained above 1117, adequate identification of an
alternative measure by the complainants is a prerequisite of meeting their burden to make a prima
facie case that such measure "is less trade restrictive, makes an equivalent contribution to the
relevant objective, and is reasonably available". 1118 As the Appellate Body pointed out, the
complainants' identification of an alternative measure should, at a minimum, enable comparison
with the challenged measure in terms of the relevant legal elements.
1119 An alternative measure
may be found not to be reasonably available, for example "where it is merely theoretical in

and 60; Mexico's first written submission, para. 206, and response to Panel question Nos. 44, 47, and 55.
1109 Further to the parties' explanations, we use the term "traceability" as a general term to describe the
tracking of a given product and "trace-back" to specifically denote traceability from the birth of an animal to
the retail sale of a resulting muscle cut of meat. See parties' responses to Panel question No. 54, and

1119 Specifically, the Appellate Body has referred to a complainant's identification of "a possible
alternative measure that is less trade restrictive, makes an equivalent contribution to the relevant objective,
and is reasonably available" See Appellate Body Reports, US – COOL, para. 379. As explained, a full analysis of
the complainants' Article 2.2 claims requires a comparison of the amended COOL measure with the
complainants' suggested alternatives. See section 7.6.1.2 above.
WT/DS384/RW • WT/DS386/RW

nature".1120 Likewise, adequate identification of the alternative is essential for determining the
alternative measure's trade-restrictiveness and degree of contribution in comparison with the
challenged measure. We therefore consider the co mplainants' explanations of the implementation
of trace-back by the United States to be of ce ntral importance to their burden of proof and our
examination of the complainants' third alternative measure.
7.507. We note that the complainants describe the third alternative measure with reference to
various examples of traceability and trace-back programs in the United States and other countries,
which are discussed below. In their arguments on the third alternative, the parties also reference
the costs associated with other traceability and trace-back programs. The complainants accept that
a trace-back system for muscle cuts from US-slaughtered animals would entail costs.
1121 They
argue that such costs would be distributed througho ut the supply chain and would thus fall evenly
on all market participants, whether foreign or domestic. This would allegedly eliminate the
disincentive to use imported livestock and the disproportionate costs borne by foreign producers
under the amended COOL measure.
1122
7.508. The United States asserts that the estima tion of the cost of a trace-back system is a
complex undertaking, requiring extensive stakeholder outreach. 1123 In its view, a trace-back
system – even one designed in general terms – wo uld significantly increase the costs associated
with recordkeeping and verification as well as labelling. 1124 According to the United States, the
complainants' suggested trace-back regime would not merely impose costs on the domestic
market, but also on foreign producers who would need to develop compatible trace-back
programmes.
1125 The United States argues that costs associated with a trace-back regime would
amount to several billions of dollars 1126, leading to changes in the industry that are difficult to
predict, including increased consolidation and a dramatic slowdown in the slaughtering process.1127
7.509. Given the parties' extensive reference to the costs entailed by the third alternative 1128,
we examine the trace-back system proposed by the complainants with regard for the evidence and
arguments on its associated costs. To the extent that such evidence and arguments are advanced
to describe the complainants' third alternative, the issue of costs may be relevant for assessing
whether they have met their burden of adequately identifying a "trace-back" measure. In addition,
the costs imposed by an alternative measure may be directly relevant to whether such a measure
can be considered reasonably available to a responding Member.
1129 The potential costs of trace-
back are further relevant to examine the validity of the complainants' arguments on the
relationship between costs and trade-restrictiveness.

Gambling, para. 308) (emphasis added).
1121 See, e.g. Canada's first written submission, para. 178; and Mexico's first written submission,
para. 209.
1122 Canada argues that "while a trace-back system would entail costs for tracking throughout the supply
chain, the fact that these costs would be related to each individual animal or group of animals – irrespective of
the country of origin – means that the costs would fall evenly on all market participants, whether foreign or
domestic." Canada's first written submission, para. 178 (footnotes omitted). Mexico contends that "this
alternative would accurately and comprehensively fulfil the objective of the COOL Measure and yet not
discriminate against imports in the sense that it would eliminate the option of restricting trade in imports and
as well as the option of discounting the price of imports as the most commercially viable option to comply with
the Amended COOL Measure. Thus, costs of the mandatory labelling would be spread evenly throughout the
market." Mexico's first written submission, para. 200.

1127 See United States' opening statement at the meeting of the Panel, para. 52.
1128 See generally parties' responses to Panel questions Nos. 39-41. This is notably reflected in Canada's
position that there is a certain level of compliance costs that a non-discriminatory alternative measure could
entail that would generate trade impacts equivalent to or greater than those of the amended COOL measure.
See Canada's second written submission, paras. 94-95; response to Panel question No. 40; and

Canada as to the magnitude of those costs required to have equivalent trade effects to the original COOL
measure. See section 7.6.5.1.3 above.

7.510. We turn to the complainants' identification and description of the proposed trace-back
system with particular focus on the parties' arguments on the implementation and related costs of
such a measure. We are guided by the Appellate Body's clarification that a party bearing the
burden in the context of an alternative measure's reasonable availability "must support such an
assertion with sufficient evidence", and "provide evidence … substantiating the likely nature or
magnitude of the costs that would be associated with the proposed alternative, as compared to the
current system".
1130
7.6.5.4.1 Implementation and costs of the third alternative measure
7.511. According to Canada, a trace-back system would involve three stages: (i) from the birth of
the animal to the slaughterhouse; (ii) the killing of the animal and the division of the carcass into
cuts at the slaughterhouse; and (iii) the delivery of cuts from the slaughterhouse to the consumer
through the distribution chain. 1131 The first stage, birth to slaughterhouse, would entail three
pillars: (a) premises identification; (b) animal identification; and (c) animal movement. 1132
According to Canada, full implementation of the animal movement pillar would not be necessary
because not all animal movements are relevant (e.g. animal movements to an auction facility). 1133
The table below represents graphically the structure of Canada's suggested trace-back system.

7.512. Although Canada refers to dispensable as pects of the third pillar and Mexico does not
explicitly adopt these stages, the complainants' general description of the third alternative
suggests that trace-back would, at a minimum, be required to maintain some continuity between
the livestock and meat products being traced, from birth through the slaughter process and up to
the point of retail sale.
1134 We note that the United States does not contest the general relevance
of these phases for trace-back. We therefore adop t the general framework of these distinct stages
and pillars to assess the trace-back system suggested by the complainants.

the Appellate Body was referring in that case to the respondent's burden under Article XX of the GATT 1994 to
show that an alternative measure would impose an undue burden. See also Appellate Body Report, Korea –
Various Measures on Beef, para. 181. As acknowledged by Mexico, it is the complainants' burden under
Article 2.2 of the TBT Agreement to make a prima facie case that their proposed alternatives are less trade
restrictive, reasonably available, and make an equivalent contribution to the objective of the amended COOL
measure. See Mexico's second written submission, paras. 114-117.

7.6.5.4.1.1 Stage 1: Trace-back from birth to the slaughterhouse
7.513. With respect to the first stage of the proposed trace-back system, namely from animal
birth to the slaughterhouse, the complainants refer to two US traceability programmes: the
National Animal Identification System (NAIS) and the 2013 Final Rule on Traceability for Livestock
Moving Interstate (Interstate Livestock Traceability Rule).
7.514. The NAIS was first proposed in 2002 and primarily concerned the protection of commercial
interests from the potential harm associated with the outbreak of an animal disease.
1135 To this
end, the NAIS aimed "to achieve the ability to id entify and trace animals of interest within 48
hours of an animal disease problem" with "rapid access to reliable and complete data on both
animal ID and movement history".
1136 Further, "[t]o collect the requisite information, NAIS was
composed of three sequential components – premises registration, animal identification, and
animal tracking." 1137 This "was based on a state-federal-industry partnership", and that, while
some states mandated some components of animal identification, "at the federal level, NAIS was a
voluntary program".
1138
7.515. In 2010, the USDA decided "to replace NAIS with a more flexible, state-based program
that mandates traceability only for livestock moving in interstate commerce." 1139 The result was
the Interstate Livestock Traceability Rule under which, "unless specifically exempted, livestock
belonging to species covered by the regulations that are moved interstate must be officially
identified and accompanied by an interstate certificate of veterinary inspection or other
documentation."
1140 According to the United States, the Interstate Livestock Traceability Rule
"represents a significantly more modest approach to the problem than the previously contemplated
[NAIS]".1141 Generally speaking, the Interstate Livestock Traceability Rule currently creates
traceability for an animal's movement between the slaughter facility and the state the animal was
in at 18 months of age.
1142
7.516. For the general costs of the first stage of trace-back, the complainants refer to cost
assessments related to each of these traceabili ty programs. Canada argues that it has been
documented that implementing full animal traceability under the NAIS would have added about
USD 5.97 per head to the costs of cattle, an d USD 0.06 per head to the costs of hogs. 1143 In total,
implementing NAIS was estimated to cost the fe deral government of the United States between
USD 23.8 and 33 million annually. The same estimate concluded that the cost would be partially
offset by direct benefits in the form of cost savings achieved through NAIS. Further, NAIS would
have provided the government with "an array of 'indirect benefits' that are difficult to empirically
value".
1144 Full traceabilit y, that is to say 100% NAIS participation, would have cost around
USD 210 million annually to the US cattle industry and USD 6.4 million a nnually to the US hog
industry.1145 Put in perspective, Canada argues, this re presents less than a quarter of 1% of the
retail value of US beef products.1146
7.517. Mexico submits a summary of an economic analysis conducted by the USDA to assess the
economic impact of implementing the Interstate Livestock Traceability Rule on the cattle
industry.1147 This analysis combined compliance costs with official identification and interstate
movement documentation components of the rule, concluding that "annual incremental costs

would range from a total of USD 5.5 million to USD 7.3 for producers who combine official
identification eartagging with current management activities, to USD 14.5 million to USD 34.3
million for producers who would handle their cattle solely for compliance with the regulation, or a
cost per animal range from USD 0.18 to USD 12.18."
1148 According to the USDA, the estimated
cost was minimal and represented only a "small fraction" of the value of US cattle and calf
production, which was estimated at USD 31.8 billion in 2009.1149
7.518. With respect to the specific sub-compon ents (three pillars) of the first stage, the
complainants do not advance explanations or data on the costs for implementing premises
identification, i.e. the first pillar of the first st age of the proposed trace-back system. As to the
second pillar of the first stage, Canada notes th at the USDA observed that implementing a single
ear tag approach to comply with animal identification requirements under the Interstate Livestock
Traceability Rule could be cost-efficient to producers, as evidenced by other countries' practice. 1150
For the third pillar, Canada points out that the NAIS involved tracking animal movements in one of
the NAIS-compliant animal tracking databases.
1151 Canada also claims that tracking cattle
movements is not as costly as the United States portrays it, and that tracking cattle movements
under the NAIS was estimated to represent at most one fifth of the costs associated with
implementing the NAIS for the cattle industry.
1152
7.519. In response, the United States points out that the NAIS analysis referred to by Canada
only provides an assessment of an existing and limited voluntary system. According to the
United States, the analysis assesses only the direct costs of replacing the existing tagging and
branding systems with an electronic system. Moreover, the NAIS was limited to identifying animals
only from birth to slaughter, where identification is maintained through carcass inspection.
1153
The United States also questions the relevance of the Interstate Livestock Traceability Rule based
on the fact that its costs are incurred primarily by ranches and feed lots as opposed to
downstream entities such as slaughter facilities, processors, and retailers.
1154 The United States
notes that the costs of a trace-back system would be substantially greater for its cattle than its
hog industry. The former is far more complex than the latter, requiring the tracking of each
individual head of cattle. By contrast, the hog indu stry is far more integrated and trace-back could
be based on batches of swine instead of individual animals.
1155 According to the United States, this
would mean that 90% of the costs of the NAIS would fall on its cattle industry.1156
7.520. We recall the complainants' argument that the third alternative measure would eliminate
the need to segregate livestock and muscle cuts according to country of origin. The Interstate
Livestock Traceability Rule may give support to this contention as regards livestock. As the
United States explains, under the Interstate Livestock Traceability Rule, "there is no need to
physically segregate different animals as all covered animals have an official identification number
on an ear tag (or through some other means)."
1157 Further, the United States adds that "[a]t the
time the animal receives its identification number, all animals are treated the same, regardless of
whether any particular animal has spent time outside the United States previously."1158

1148 See Exhibit MEX-86, p. 1; and Mexico's response to Panel question No. 62, para. 139. In connection
with the fourth alternative measure, Canada cites cost estimates provided in the final Interstate Livestock
Traceability Rule that differ slightly from the estimates for the proposed rule relied upon by Mexico. For
example, according to Interstate Livestock Traceability Rule, "[t]he combined annual costs of the rule for cattle
operations of official identification and movement documentation will range between $14.5 million and $34.3
million, assuming official identification will be undertaken separately from other routine management practices;
or between $10.9 million and $23.5 million, assuming that tagging will be combined with other routine
management practices that require working cattle through a chute." Interstate Livestock Traceability Rule,

7.521. However, the trac eability of interstate animal moveme nts under the Interstate Livestock
Traceability Rule differs substantially from the type of trace-back system contemplated in the
complainants' third alternative measure. As pointed out by the United States, the Interstate
Livestock Traceability Rule provides for notable exceptions from the requirement that animals
moving interstate have an official identification number and be accompanied by an interstate
certificate of veterinary inspection (ICVI)
1159 or other document. 1160 Apart from the limitation of
coverage to animals moving interstate, the Interstate Livestock Traceability Rule exempts cattle
intended for slaughter that are under the age of 18 months from the requirement to have an
official identification number. 1161 Further, the United States notes that "animals that are 'moved
directly to a recognized slaughtering establishment' (which includes all animals imported for
immediate slaughter) are exempt from the system en tirely in that they do not need an official
identification number or an ICVI".
1162
7.522. Given these differences, th e evidentiary value of the Inters tate Livestock Traceability Rule
is at best limited in respect of the implementa tion and the potential costs of the complainants'
third alternative measure. The Interstate Livestock Traceability Rule represents only a fragment of
the first stage of trace-back, unlike the more comprehensive trace-back from animal birth to retail
muscle cut under the complainants' proposal. Inde ed, Canada acknowledges that the Interstate
Livestock Traceability Rule framework "would be insufficient for the first stage of a trace-back
system (i.e. the three pillars of an identifica tion and traceability system for livestock)".
1163
Consistent with the narrower scope of the Interstate Livestock Traceability Rule, the United States
indicates that its "regulatory impact analysis estimated the incremental costs of additional
measures associated with the interstate traceability requirements for all dairy cattle and beef
cattle at age 18 months or older."
1164
7.523. Further, the Interstate Livestock Tracea bility Rule does not appe ar to provide origin
information on US livestock imports in Categories B and C. For Category B, as mentioned, the
average age at which Category B feeder cattle are imported into the United States is typically
within the first year of their lives (before they are 18 months old). By tracking only interstate
movements long after animals have been in the United States, the Interstate Livestock Traceability
Rule does not provide information on a relevant portion of the animal's life history. Canada states
that "the USDA has confirmed that feeder cattle (cattle under 18 months of age) 'will be subject to
the official identification requirements in a future rulemaking'. It is Canada's understanding that
the program will apply to all ages of cattle as of 2015."
1165 At the same time, in asserting that that
"the costs could not be greater than the estimate d costs under the NAIS", Canada recognizes that
"the costs of covering these animals [i.e. animal less than 18 months older] under the [Interstate

requirements. While brands may be used as official identification for cattle moving interstate in accordance
with the provisions of this final rule, the branding of imported cattle from Canada and Mexico is not intended to
provide official individual identification, but is rather a permanent mark used to designate the country that
exported the animal." Interstate Livestock Traceability Rule, p. 2048.
1159 Under the Interstate Livestock Traceability Rule, the ICVI is defined as "[a]n official document
issued by a Federal, State, Tribal, or accredited veterinarian certifying the inspection of animals in preparation
for interstate movement", and further required to show inter alia "the species of animals covered by the ICVI;
the number of animals covered by the ICVI; the purpose for which the animals are to be moved; [and] the
address to which the animals are destined". See Interstate Livestock Traceability Rule, § 86.1.
1160 See United States' response to Panel question No. 62, para. 139; Interstate Livestock Traceability
Rule, § 86.5(c).
1161 See United States' response to Panel question No. 62, para. 139 (citing Interstate Livestock
Traceability Rule, § 86.5(c)(7)(ii)). According to the United States, "[t]here was significant opposition by the
U.S. cattle industry to extending the traceability regime back to birth." United States' response to Panel
question No. 62, footnote 126 (citing Interstate Livestock Traceability Rule, p. 2047: "Other commenters
stated that the sheer number of animals that will be required to be identified and tracked under these
regulations will make including feeder cattle very costly for producers, veterinarians, sale barns, and State
agencies and that the volume of information that will need to be generated may swamp the whole system, for
no significant benefit.").

Livestock Traceability Rule] are not known to Canada". 1166 Mexico does not directly address the
implications of extending traceability to Category B livestock imports for the relevance of its cost
assessments and implementation of the first stage of trace-back.
1167
7.524. The evidence before us also suggests that Category C cattle would fall into the Interstate
Livestock Traceability Rule's exemption for animals "moved directly to a recognized slaughtering
establishment".1168 Canada states that "[e]ven if an ICVI is not required for cattle moved directly
to a slaughterhouse, such cattle must be accompanied by an 'owner-shipper statement'." 1169
Although the "owner-shipper statement" is defined in such a way as to include potentially relevant
origin information, Canada only argues the applicability of such information in the context of its
fourth alternative measure, without indicating whether and how it would serve for the third
alternative. Mexico does not address the tracking of animals imported for immediate slaughter in
connection with the third alternative's implementation or cost estimates.
7.525. To the extent that the complainants adduce cost estimates based on a traceability system,
such as the Interstate Livestock Traceability Rule, that does not apply to the majority of imported
animals in Categories B and C, such evidence is of limited assistance in assessing an alternative
measure designed to convey origin information on muscle cuts derived from such animals. Like the
first two alternatives, the complainants' third alternative measure would cover all muscle cuts from
US-slaughtered animals, including animals born and/or raised outside the United States. While the
NAIS may have extended to such animals, we note the program's voluntary nature, and the
limited participation in its premises registration. In light of the complainants' limited arguments in
this regard, we are unable to ascertain the relevance of the Interstate Livestock Traceability Rule
and the NAIS for the implementation and costs of the first stage of their third alternative.
7.526. With regard to the specific sub-divisions of the first stage, the complainants provide only a
partial description, particularly as to what the first and third pillars would consist of and how they
would be implemented. For the first pillar, neither complainant has explained the exact manner of
premises identification to be included in the third alternative measure.
7.527. For the third pillar, Canada states that full implementation of animal movement traceability
would not be necessary because not all animal movements are relevant.
1170 Canada explains that
"the system would only need the reporting of the bi rth of an animal on a farm and the presence of
an animal on a farm or feedlot where it is bein g raised" to provide information on where livestock
were born, raised, and slaughtered.1171 In response to the Panel's request for clarification, Canada
addresses the dispensability of the third pillar with respect to its own traceability system: "for the
purpose of fulfilling the United States' objective and in order to make a trace-back system in the
United States non-discriminatory and less trade-restrictive than the amended COOL measure, the
third pillar of Canada's system for cattle may not be strictly necessary."
1172

1166 Canada's response to Panel question No. 74, para. 183. While this is presumably based on the fact
that the NAIS envisaged complete first-stage traceability, it takes no account of the voluntary nature of the
NAIS nor the limitations of the NAIS costs assessments put forward. See United States' second written
submission, para. 134 (asserting that the NAIS cost analysis evaluated "only 'direct' costs of changing the
tagging and branding systems in place to an electronic system" and that identification was only "maintained
through carcass inspection") and para. 151. See also Exhibits CDA-133 and CDA-92, p. 22.
1167 Similar to Canada, Mexico states that "rule-making concerning traceability for this category of
livestock is expected in the near future". Mexico's response to Panel question No. 63, para. 136.
1168 See para. 7.241 above.
1169 Canada's comments on the United States' response to Panel question No. 63, para. 99 (citing
Interstate Livestock Traceability Rule, § 86.5(c)(1)). Canada additionally notes that an "owner-shipper
statement" is defined as "[a] statement signed by the owner or shipper of the livestock being moved stating
the location from which the animals are moved interstate; the destination of the animals; the number of
animals covered by the statement; the species of animal covered; the name and address of the owner at the
time of the movement; the name and address of the shipper; and the identification of each animal, as required
by the regulations, unless the regulations specifically provide that the identification does not have to be
recorded". Canada's comments on the United States' response to Panel question No. 63, para. 99 (citing
Interstate Livestock Traceability Rule, § 86.1) (emphasis by Canada).

7.528. These explanations imply that the third alternative would require some form of animal
movement traceability within the United States for animals raised there for any period of time
before slaughter. While Canada refers to tracking "the presence of an animal on a farm or feedlot
where it is being raised", it is unclear whether this necessarily extends to every animal movement
and raising location, or what the cost implicatio ns would be based on the amount of information
tracked. Moreover, the complainants do not account for whether this has any implications for the
comparability of the third alternative to evidence they have put forward regarding other
traceability schemes, such as the NAIS.
1173 While some unspecified element of the third pillar
might be dispensable under the first stage, the complainants have not explained what this pillar
would consist of in order to provide origin information under their third alternative measure.
7.6.5.4.1.2 Stage 2: Trace-back at the slaughterhouse
7.529. Both Canada and Mexico suggest that there are particular challenges for trace-back after
the first stage. As acknowledged by Canada, "[t]he essence of a trace-back system is to preserve
the link between the animal or group of animals and the meat (i.e. the identity of the meat)".
1174
According to Canada, "the second stage – the killing of the animal and the division of the carcass
into cuts at the slaughterhouse – is the stag e of a trace-back system where most of the
compliance costs would be entailed." 1175 While Mexico does not specifically address the costs
associating with maintaining traceability in the slaugh ter facility, it also refers to the view of some
industry participants "that linking the two systems [of animal identification and product tracking]
will be difficult and costly".
1176
7.530. The United States argues that maintaining individual trace-back for each animal once
processing has begun, on an industrial scale, would entail dramatic slowdowns in the meat cutting
process, and would add substantial burdens and costs to retailers and other vendors who would
have to associate particular cuts of meat with labels that would correspond to individual
animals.
1177 According to the United States, the cost analysis commissioned by the USDA, which
Canada relies upon, evaluates traceability only up to the point of slaughter, which is the least
expensive of the three stages of meat production. Thus, the United States claims, neither
complainant has provided any evidence as to the costs of trace-back during this stage.
1178
7.531. The importance of maintaining traceability through the slaughter process illustrates the
limitations of cost estimates confined to the first stage of trace-back. Although Canada states that
linking animal and meat "mostly concerns the seco nd stage of the system" of traceability within
the slaughterhouse
1179, it notes that the Interstate Livestock Traceability Rule framework "deals
with traceability for livestock, not meat".1180 This raises doubts as to the utility of referring to such
existing – or abandoned – systems with a view to obtaining a clear understanding of the third
alternative measure, particularly if, as Canada says, "the bulk of the costs of a trace-back system
are incurred at the second stage of the system, i.e. at the slaughterhouse."1181 The same is true of
a program like the NAIS, which applied only up to the point of slaughter. As a result, the
traceability systems referred to by the complainants for the description and costs of trace-back
stop short of bridging the very gap between animal and meat traceability that the complainants'
third alternative would have to fill in order to function.
7.532. The complainants also refer to examples of non-US trace-back systems in the context the
second stage of trace-back, specifically regarding the continuity between animal and meat

1173 For example, with respect to tracing animal movements under the NAIS, it was considered that
"[t]he minimum traceback information included: the national premises identification number (PIN); the animal
ID number (AIN) or group ID number (GIN); the date of the event; and the event itself (e.g., move-in to a
new premises or move-out of the current premises)." Exhibit CDA-92, p. 17.

identification. Canada states that "[p]reserving that link is done on a country-wide and commercial
basis in at least two WTO Members, namely Japan and Uruguay".1182 According to Canada, "[w]hile
there is no single method, Uruguay's system provides a good example of how preserving the link is
done from an operational perspective."
1183 Canada also "notes that the operations at the second
stage of the trace-back system in Uruguay are financed by a contribution from market participants
in the amount of 1 U.S. dollar per animal slaughtered." 1184 Mexico also points to trace-back
systems in the European Union, Korea, Japa n, and Uruguay, noting that "Uruguay has
implemented a comprehensive trace back system which allows tracking livestock and the meat
derived from those animals".1185
7.533. The complainants' references to other trace-back systems do not always clearly separate
the second and third stages, and appear to be made for the more general illustration of
maintaining the link from animal birth to retail sale. Therefore, some of this evidence may be
understood to have potential relevance for both the second and third stages of trace-back. We
accordingly address other trace-back systems below in connection with any relevant clarification
they provide as to the overall implementation of trace-back under the third alternative.
1186
7.6.5.4.1.3 Stage 3: Trace-back from slaughterhouse to retail
7.534. Canada notes that "[t]he third stage of a trace-back system involves the distributors and
the retailer. … The distributors and the retailer have to preserve the information about the muscle
cut, including if further cutting is done."
1187 Mexico foresees that the third alternative measure
"will cover the production steps after delivery of the animals to the slaughterhouse up to the point
of sale to the consumer."1188
7.535. In addition to these general descriptions, Canada and Mexico both reference the trace-back
system in Uruguay with respect to the post-slaughter stages of the third alternative measure,
again without clear distinction between the second and third stages.
1189 With specific regard to the
costs of the third stage, i.e. beyond the slaughterhouse, Canada contends that Japan's experience
shows how the costs of conveying information to consumers under a trace-back system may be
borne directly by governments rather than busine sses. According to Canada, bearing the costs of
correctly conveying information to consumers, for instance by maintaining a website, could reduce
labelling costs to market participants.
1190
7.536. The United States responds that the third stage of trace-back would require each retailer
to provide consumers with the ability to trace each individual cut of beef back to an individual
animal. According to the United States, this would be especially costly for retailers that further
process and cut the meat they receive from slaugh terhouses, as such retailers would need to set
up potentially complicated processes to ensure that each cut that was further processed would
continue to retain traceability. 1191 The United States maintains that those procedures would add
substantial burden to retailers and other vendors, who would have to associate particular cuts of
meat with labels that would correspond to the individual animal.

United States argues that neither complainant provides estimates or adequate evidence of the
costs incurred in later stages leading to retail.1193
7.537. Given the complainants' treatment of the se cond and third stages in their descriptions of
trace-back, we address the third stage and the re levance of other trace-back systems below in
connection with the overall implementation of trace-back under the third alternative.
7.6.5.4.1.4 Overall implementation and costs of trace-back
7.538. The complainants' evidence and arguments le ave significant gaps as to the three separate
stages that would need to be linked under the third alternative measure. As noted, for the first
stage, the complainants cite certain traceability programs within the United States that have more
limited coverage and applicability than that required under the third alternative measure.
The complainants' point to more comprehensive trace-back schemes in other countries, but have
claimed that these are illustrative of feasibility and not necessarily indicative of the exact trace-
back that would be implemented in the United States.
7.539. To obtain an overall view of the implemen tation and costs of a trace-back system within
the United States, the complainants' description would need to be examined beginning with the
birth of livestock, including livestock born abroad. In this regard, Canada and Mexico contend that
they currently (or imminently in the case of Canadian hogs) have in place traceability systems that
could supply relevant origin information for animals exported to the United States.
1194 To the
extent that the third alternative covers muscle cuts from all US-slaughtered animals, this may be
relevant for a complete review of the implementation of a comprehensive US trace-back system
for such muscle cuts. However, we are not in a position to carry out such a review, given the
uncertainties in the complainants' description of trace-back following the animals' entry into the
United States.
7.540. We understand from the complainants' de scriptions that the third alternative could be
implemented in the United States through a variety of different tracking technologies and
informational systems. For example, Canada states that its own identification and traceability
systems will provide relevant origin information through individual ear tag numbers for live cattle
and group tattoo numbers for hogs up to the point of export. According to Canada, "[t]his number
could be transferred to the US system electronically, depending on an electronic system being in
place in the United States to receive the data."
1195 Canada further argues that "[t]here is no
indication that the cost of transferring the origin information from Canada to the United States
would be higher than the costs of linking any data base established by the United States under the
first phase of a trace-back system with any database established by it under the second or third
phases of a trace-back system."
1196 Similarly, Mexico explains that applicable rules already require
that its cattle exports bear an ear tag "that can be used to trace the animal, including the State of
origin, the ranch which the cattle belongs to, and complete information about its producer". 1197
Mexico states that "[t]here are many methods of animal identification and traceability available
today, for example, ear tags and electronic methods".1198

response to Panel question No. 68, para. 108 (citing Interstate Livestock Traceability Rule, p. 2058:
"Additionally, within beef operations, over 60 percent of calves had some form of individual identification. […]
Additionally, with an array of official eartags, producers may choose a single eartag that meets both
management and official identification needs. This option would make the additional cost of official eartags
quite small.").

7.541. We note that there are a number of methods of animal id entification – the second pillar of
the first stage of trace-back – with potentially varying costs. 1199 The NAIS cost analysis referenced
by Canada made certain assumptions as to the type of identification system used. For instance,
"[i]n the cattle (bovine) industry, it was assumed the technology used for animal identification
would be electronic identification (eID) using Radio Frequency Identification (RFID) ear tags and
identification would be on an individual animal basis."
1200 For swine, the study "assumed market
hogs would be identified with a group/lot ID and cull breeding stock would be identified with a
unique visual premises ear tag". 1201 Any resulting cost estimates may be of assistance only to the
extent the complainants' third alternative adopte d these and other operational assumptions, but
would not be directly or at all comparable to, an d hence relevant for, any trace-back system that
employed other means. The complainants do not specify whether and to what extent their third
alternative would incorporate such operational assumptions used with respect to other traceability
programs.
7.542. A further difficulty of assessing the overall implementation and costs of the third
alternative arises with respect to the retrieval and management of trace-back information.
Canada's description of the third alternative measure envisions the possibility of establishing some
form of "database".
1202 According to the United States, "[a]t present, there is no searchable
electronic data base at the national level" and "[t]he vast majority of states do not have
searchable electronic databases either".1203 Traceability of animal movements under the Interstate
Livestock Traceability Rule occurs "by following the paper trail that animal has created through
ICVI's that are on record in the livestock facilities that the animal has resided in."
1204 While Canada
points to certain mechanisms that could facilitate the management of information under a trace-
back regime1205, it leaves unclear the manner of data storage, management, and retrieval – as
well as related costs – that would form part of the third alternative. For its part, Mexico discusses
its own readiness to export cattle equipped for trace-back purposes 1206, but does not explain the
sort of information tracking and storage that would exist within in the United States through later
stages of its third alternative measure.
7.543. Both complainants seem to distinguish tr ace-back from the COOL recordkeeping and audit
requirements. In particular, they contend that the COOL statute's prohibition of a mandatory
identification system necessitates use of the la tter at the expense of Canadian and Mexican

1199 One source notes that that, apart from branding, "[o]ther methods of animal identification include
tattooing, retina scanning (Optibranding™), iris imaging, and, currently the most common method, tagging.
Tags may have simple printed numbers, imbedded microchips, or machine-readable codes, such as radio
frequency identification (RFID). Ear tags cost in the neighborhood of $1 or $2 apiece. RFID technology is more
costly, with instruments for reading RFID tags costing several hundred dollars apiece, though prices have been
rapidly falling." Exhibit CDA-86, p. 28. Another source refers to "tags, radio frequency identification devices,
and other ID devices" capable of bearing "a unique, 15-digit" animal identification number. Further, "[i]n
recent years, the use of RFID devices and injectable transponders with information that is read by scanners
and fed into computer databases is becoming more common, because these devices allow for faster, easier
access to information." Exhibit CDA-92, p. 16.

1203 United States' response to Panel question No. 62, para. 137.
1204 United States' response to Panel question No. 62, para. 137. As the Interstate Livestock Traceability
Rule relies on the "paper trail" of ICVIs on record in livestock facilities or animal identification by other
documents created in the ordinary course of business, the United States explains that "the current traceability
regime for animal movements is considered a 'book end' system." See United States' response to Panel
question No. 62, footnote 128.
1205 Canada notes that "APHIS provides information systems that the states and tribes may use at no
charge" and "[a] state or tribe may also decide to develop its own system". Canada's comments on the
United States' response to Panel question No. 62, para. 89 (citing the Interstate Livestock Traceability Rule,
p. 2059). Canada further states that "[u]nder the NAIS, a producer would select one of the NAIS-compliant
animal tracking databases (ATDs) maintained by states and private industry to report the movements of an
animal. The USDA would operate a 'portal system' to enable health official to submit requests for information
to the administrators of the ATDs. Thus, there was no single database. However, that would not have been an
obstacle to an efficient traceability system for livestock (the first stage of a trace-back system)." Canada's
comments on the United States' response to Panel question No. 63, para. 93 (footnotes omitted).
1206 See Mexico's responses to Panel questions Nos. 57-59.
WT/DS384/RW • WT/DS386/RW

livestock.1207 However, there are indications that these systems might not be so clearly
dichotomous, as the complainants' explanations suggest that the third alternative measure could
entail elements of recordkeeping and audit simi lar to that under the amended COOL measure. 1208
For example, Canada describes mitigation of tr ace-back costs through reducing the amount of
label information, but states that "market participants would nevertheless have to be able to
demonstrate, if audited, that a muscle cut derives from an animal (or group of animals) that was
born, raised and slaughtered at a specific location (farm, feedlot, slaughterhouse)."
1209 Thus, we
understand that the third alternative measure could possibly require audit capability of records for
even more information than that required under the amended COOL measure, with possible cost
implications that the complainants do not address. 1210 Ultimately, the complainants' explanations
do not resolve these basic questions, and leave us in doubt about the existence, amount, manner,
and resulting costs of recordkeeping and audit under the third alternative measure.
7.544. The lack of clarity on the complainants' third alternative measure is compounded by their
explanations of the eventual muscle cut labels. Fo r example, Canada states that the label "would
provide consumers with information, not only in respect of country of origin, but on the precise
name and location of the farm, feedlot and processi ng facility (i.e. state/province, municipality, or
specific address)."1211 Canada further describes the following labelling flexibility as follows:
Under a trace-back system, the label could indicate the precise name and address of
the farm, feedlot and processing facility where each of the production steps took
place. However, the costs of labelling could be mitigated by reducing the information
conveyed on the label. The labelling requirements under a trace-back system could be
the same as those under the amended COOL measure.
1212
7.545. Mexico similarly proposes that the third alternative could provide detailed information on
where the animals were born, raised, and slaughtered1213 as follows:
[A] "Product of U.S." or similar label that is based on a "born, raised and slaughtered"
rule will be permissible under this alternative as well as the more detailed information
on where the animal was born, raised and slaughtered. This [third] alternative
provides the United States with flexibility in establishing the labeling conditions.
1214
7.546. Both complainants thus frame their third alternative in flexible terms as to what
information the label would convey to consumers. At the same time, the complainants seem to
presuppose that the trace-back system would entail tracking more detailed information than under
the amended COOL measure, irrespective of the information actually labelled. Ultimately,
the complainants do not explain whether and to what extent the method and costs of traceability
across the three stages of trace-back would depend on the information being labelled. Nor do they

1207 See Canada's first written submission, paras. 172 and 178; Mexico's first written submission,
paras. 202-203 (both citing Hayes and Meyer paper, p. 7).
1208 In this connection, we note that the Hayes and Meyer paper refers to "some mixture of both
systems". Hayes and Meyer paper, p. 8. In addition, the paper factors the costs of "labels, additional record
keeping, audit compliance and labor" into its trace-back costs estimates. Hayes and Meyer paper, p. 9
(emphasis added).
1209 Canada's second written submission, para. 120 (emphasis original).
1210 Such recordkeeping burdens would likely extend throughout the entire supply chain, as "the
ultimate disposition of a meat product is often not known at any particular stage of the production chain". See
para. 7.272 above; Appellate Body Reports, US – COOL, para. 344. As stated by the Hayes and Meyer paper
with respect to the US pork industry, "all pork sold through US retailers will have to be identified and traced.
Since it is not likely that 'retail' and 'foodservice' production systems will be segregated, all U.S. born, raised
and slaughtered pork (since any of it may enter the retail channel), and all pork from feeder pigs or slaughter
pigs imported from Canada would be subject to traceback." Hayes and Meyer paper, p. 9.
1211 Canada's first written submission, para. 169.
1212 Canada's second written submission, para. 120 (footnote omitted). Canada adds that "[i]nstead of
displaying all the information on the label, the label could instead contain a bar code that consumers could
scan using a scanner made available in the store. Another possibility is to put an identification number on the
label, as in Japan, to allow consumers to obtain the information through a website, which they could access in
the store with their smartphones." Canada's second written submission, para. 120, footnote 208.

clarify the implications of any differences between the information kept in the supply chain and
eventually conveyed to consumers under their third alternative.
7.547. Finally, the various foreign trace-back systems referred to by complainants do not explain
how these are meant to elucidate the implementati on of trace-back in the context of the US
livestock and meat market. Third parties to this dispute with trace-back systems cited by the
complainants have cautioned against drawing undue comparisons between the regimes adopted by
different Members.
1215 These third parties have also provided descriptions of their trace-back
systems1216, in some cases revealing potentially important differences from the complainants' third
alternative measure and its requirement of verifiable trace-back from the birth of an animal to the
retail sale of its muscle cut meat.1217
7.548. In other cases, such as the trace-back system of the European Union, continuity across the
three stages appears to be maintained 1218, but the complainants do not account for how certain

1215 Australia notes "that the information from third parties may inform the Panel as to other trace-back
practices", but that "the subject of these proceedings is the compliance of measures applied by the US and not
measures and systems in place in other WTO member countries." Australia's response to Panel question
No. 68. The European Union avers that "simply because a measure is reasonably available to one Member that
does not necessarily mean that it is reasonably available to another Member, within the meaning of Article 2.2
of the TBT Agreement and/or that it fulfils the level of protection chosen by the Member concerned." European
Union's response to Panel question No. 68, para. 46. New Zealand states that "while the [its trace-back]
scheme works well for New Zealand’s purposes and in the New Zealand context, New Zealand is unable to
comment on the extent to which this experience can inform the reasonable availability of a trace-back measure
in the United States to provide origin information to consumers." New Zealand's response to Panel question
No. 68, para. 8. Japan states that "[s]ince production and distribution systems vary from country to country,
we are not in a position to be able to express a view regarding the extent to which Japan’s Cattle Identification
and Traceability System corresponds to the complainants' suggested trace-back system and in what way, if
any, it could be relevant for the reasonable availability of the trace-back system." Japan's response to Panel
question No. 68.
1216 For example, Australia explains that it has in place the "National Livestock Identification System
(NLIS)" "for the identification and traceability of cattle, sheep and goats. The NLIS is a centralised system
which records movement of livestock through the supply chain from farm to slaughter." This system entails
premises identification of "livestock producing properties, saleyards and abattoirs" and animal identification by
means of "individual electronic identification devices (ear tags and/or rumen boluses) for cattle". Traceability to
premises is maintained during slaughter and "carcasses are identified … enabling the continuation of
traceability throughout the slaughter and processing chain." The Australian Department of Agriculture is
responsible for supervision and audit activities to verify "effective operation of the systems in place".
Australia's response to Panel question No. 68.
In Japan, "the Cattle Traceability Act stipulates that it is obligatory to record cattle’s information
including the date of birth and movement history of each animal for the purposes of preventing the spread of
BSE and promoting the provision of individual identification information." This includes requirements for
"producers to report the movement history information of each animal at every stage, from its birth to
slaughter" to an independent administrative agency. These "reports must contain each animal's individual
identification number, date of birth or date of importation, sex, species, individual identification number of its
mother, information of its movement (the farm(s) that raised the animal), date of movement, and date of
slaughter, death or export." Cattle are equipped with ear tags with their identification number when they are
born or imported. "After cattle are slaughtered, the package of beef product must show the individual
identification number of the animal the beef is derived from down to the retail stage." Consumers can access
the animal's information by searching the identification number on a designated website. Japan's response to
Panel question No. 68.
1217 Australia repeatedly refers to food and product safety as elements of its trace-back system,
including in connection with animals "that may pose a biosecurity or health risk" and declarations of "essential
information about the food safety status of the livestock". Australia's response to Panel question No. 68.
New Zealand explains that it "has a National Animal Identification and Tracing (NAIT) scheme that provides for
traceability from birth to death or live export of animals". This scheme is mandatory for cattle and is
administered by a company owned by various industry bodies. New Zealand's response to Panel question
No. 68, para. 1. New Zealand notes that its NAIT scheme covers the three pillars of the first stage of trace-
back. New Zealand's response to Panel question No. 68, para. 6. However, "[a]s to the second and third
stages, the NAIT scheme is not designed to provide traceability past death or live export." New Zealand's
response to Panel question No. 68, para. 6.
1218 The European Union explains that its regulations require "the establishment of a system for the
identification and registration of bovine animals, including a computerised database. Animals are identified by
an ear tag applied to each ear for life, with the same unique code establishing the birth place. Each moving
animal is accompanied by a passport and its movements registered. A compulsory label for beef indicates
where the animal from which the beef is derived was born, fattened and slaughtered. … Beef from third
countries must at least be labelled as non-EU origin, together with the place of slaughter." The European Union
WT/DS384/RW • WT/DS386/RW

features, such as the use of "batch traceback", would be applied in the United States under the
third alternative measure. 1219 There is also evidence to question the general comparability of
conditions in the European Union and the United States for the implementation of trace-back.
For instance, the Hayes and Meyer paper, which the complainants invoke, refers to several
"key advantages" in the European Union for the implementation of trac e-back, including prior
mandatory animal identification, smaller EU plant size and slower line speeds, and other particular
features of the EU pork industry.
1220
7.549. Similarly, we understand the complainants' references to the trace-back systems of Japan
and Uruguay as being made for the general proposition that trace-back through the stages of
animal, carcass, and muscle cut is feasible.
1221 The complainants do not cite any particular
similarity between the livestock and meat industri es of the different countries, nor do they adopt
any concrete features of these systems for their third alternative. While the complainants have
disputed the cost implications of the differing features of the United States' industry 1222, their
abstract reliance upon the examples of foreign tr ace-back systems provides little if any clarity
about the proposed trace-back system to be implemented in the United States.
7.550. As regards costs in general, it is clear that the complainants' third alternative would
impose costs on the affected industries and regulatory authorities involved in any trace-back
system. The complainants nonetheless contend that these costs are within the reach of the
United States as a responding Member for the purposes of Article 2.2 of the TBT Agreement.
Canada asserts that "[i]t is technically and economically feasible to establish a trace-back system
in the United States. Trace-back systems exist in other WTO Members. A trace-back system is,
therefore, a reasonably available alternative measure."
1223 Mexico similarly asserts that "the Hayes
and Meyer Paper suggests that trace-back is technically and economically feasible in the
United States and, therefore, is a reasonably available alternative."
1224
7.551. However, the complainants' references to other traceability and foreign trace-back systems
do not cohesively span the necessary stages between animal, carcass, and retail muscle cut. Nor

has also proposed indicating the country of origin or place of provenance for pork that would provide for
"identification and registration ensuring the link between the meat and the animal or group of animals from
which it was obtained, and the transmission of such information from the slaughterhouse to consumers."
European Union's response to Panel question No. 68, paras. 44-45.
1219 According to one source, this is used by EU retailers and processors who "typically do not make any
attempt to maintain the identity of the meat as it is broken down into retail packs." The Hayes and Meyer
paper discusses this in contrast to further tracing of "an individual piece of meat back to the original passport"
and "a bar codded tag for each individual retail cut … placed manually on the pack". Hayes and Meyer paper,
p. 9. The European Union states that "[i]n principle, a batch may have been raised in no more than one
country and slaughtered in no more than one country. The label must state the country or countries of rearing
and of slaughter. There is a derogation for third countries: the label need only state that the animal was reared
in a non-EU country, and the country of slaughter." European Union's response to Panel question No. 68,
paras. 44-45. According to Canada, "[t]hat link is also preserved in the EU, but it is Canada's understanding
that, while it may be possible to trace a muscle cut of beef back to an animal or group of animals, it may not
always be possible to obtain the entire life history of the animal or group of animals from the reference code
(bar code) on the label of a meat package." Canada's second written submission, para. 117, footnote 203.
1220 Hayes and Meyer paper, p. 9. It also notes that "[t]he almost universal reliance on the sale of boxed
products or retail ready packs in the U.S. would force packers to adopt the more expensive individual cut
traceback system".
1221 We note the United States' position that Uruguay does not have a system that requires consumers
to be able to trace back particular meat products to the ranch, and that related cost estimates are therefore
not relevant. United States' comments on responses to Panel question No. 40, para. 117. See also
United States' response to Panel question No. 54, para. 133, footnote 120 (citing Exhibit CDA-92, p. 41); and
Exhibit CDA-131, p. 33 ("The main objective of the SNIG to this day has been to guarantee the individual or
group traceability of bovine cattle, from slaughterhouse to the farm of origin" and not through retail or to the
ultimate consumer.)
1222 The United States contends that both Japan and Uruguay have much smaller industries and have
different types of production. See United States' second written submission, para. 155, and comments on
responses to Panel question No. 42, para. 127. Canada in particular counters this with its Sumner study on the
magnitude of trade-restrictive costs. See section 7.6.5.1.3 above. Mexico cross-refers to evidence submitted
by Canada on the cost of trace-back from farm to consumer on a per head basis in Uruguay, but does not
elaborate on its applicability to the implementation of trace-back in the United States. Mexico's response to
Panel question No. 42, para. 86 (citing Exhibit CDA-145 (BCI)).

WT/DS384/RW • WT/DS386/RW

do the complainants elaborate on the manner or cost implications of spanning these stages in the
United States under the third alternative measure. Canada outlines various forms of cattle and
swine traceability that currently exist in the United States but acknowledges that "they are not
pieced together in one single national system".
1225 Canada states that it "is not aware of the
specific costs under each of the programs" it identified at the federal and state levels with various
forms of traceability.1226 Nevertheless, "Canada understands that the costs of these programs are
well within the capacity of the United Stat es and of the relevant market participants." 1227 Mexico
cites a Congressional Research Service report from 2005 on the challenges of tracing animal
identification post-slaughter, which generally refers to linking animal and meat identification while
also reflecting the objection of the meat industry that "linking the two systems will be difficult and
costly".
1228
7.552. In conclusion, the complainants evoke distin ct stages of the third alternative for tracking
an animal's birth, slaughter, processing, and product labelling. 1229 However, the complainants do
not address each of these stages with sufficient clarity. In fact, the complainants' explanations on
the implementation and costs of the third alternat ive provide for extensive flexibility both overall
and for specific stages. As result, we lack a cohesive depiction of the complainants' third
alternative measure and the linkages between the various stages of trace-back.
7.553. Consequently, the complainants have not sufficiently explained how their third alternative
measure would be implemented in the United States. In our view, this lack of an adequate
identification of the third alternative measure prevents us from undertaking an assessment of this
alternative and meaningfully comparing it with the amended COOL measure as required under
Article 2.2 of the TBT Agreement. Arguably, on th is ground alone the complainants have not made
a prima facie case as to the third alternative measure of trace-back in the United States. This is
more clearly borne out under the separate legal elements of the comparative analysis under
Article 2.2 of the TBT Agreement, which we examine in the following sections.
7.6.5.4.2 Whether the third alternative measure is reasonably available
7.554. The Appellate Body has held that, for conducting an assessment of consistency with
Article 2.2, "[i]n most cases, a comparison of the challenged measure and possible alternative
measures should be undertaken".
1230 Further, "it may be relevant for the purpose of this
comparison to consider … whether it is reasonably available". 1231
7.555. In the context of Article XX of the GATT 1994 and Article XIV of the GATS, the
Appellate Body has stated "[a]n alternative measure may be found not to be 'reasonably available'

1227 Canada's response to Panel question No. 62, para. 158. Canada also references the building of
"traceability systems to bridge the separate animal and meat tracking systems" in general terms without
clearly indicating how this would be accomplished under the third alternative measure. Canada's first written
submission, para. 171. In this connection, there is evidence suggesting that historical factors have resulted in
the creation of "two largely distinct sets of traceability systems in the livestock/meat sector: one set for live
animals and another for meat", and that the "current challenge for the cattle/beef sector is to link these
systems and develop a system for identifying farm-level attributes in finished meat products". Canada's
reference to NAIS as a potential "building block for a trace-back system to verify designations on labels" would
similarly cover only a limited portion of the trace-back required under the third alternative. Canada's second
written submission, para. 111.
1228 Mexico's first written submission, para. 210 (citing Exhibit MEX-33, p. 11):
As the extent of traceability increases, so do likely costs. Animal ID prior to slaughter, and
product tracking after slaughter and processing, generally now are within practical reach, most
industry observers agree. However, the meat industry essentially has argued, notably in the
context of COOL, that linking the two systems will be difficult and costly. Industry officials said
new costs will be incurred in identifying and segregating animals, physically reconfiguring plants
and processing lines, and labeling and tracking the final products.

… where it is merely theoretical in nature, for instance, where the responding Member is not
capable of taking it, or where the measure imposes an undue burden on that Member, such as
prohibitive costs or substantial technical difficulties."
1232 In EC – Seal Products, the Appellate Body
further clarified this as follows:
This passage suggests that the "prohibitive costs or substantial technical difficulties"
are indeed those associated with the burden placed on a Member. At the same time,
however, this language does not foreclose the possibility that there may be other
indications that the alternative measure is "merely theoretical in nature". As we see it,
if there are reasons why the prospect of imposing an alternative measure faces
significant, even prohibitive, obstacles, it may be that such a measure cannot be
considered "reasonably available". We would not exclude a priori the possibility that
an alternative measure may be deemed not reasonably available due to significant
costs or difficulties faced by the affected industry, in particular where such costs or
difficulties could affect the ability or willi ngness of the industry to comply with the
requirements of that measure. We theref ore consider that an assessment of the
reasonable availability of an alternative measure could potentially include the burden
on the industries concerned.
1233
7.556. The Appellate Body has stated that a part y bearing the burden in the context of the an
alternative measure's reasonable availability "must support such an assertion with sufficient
evidence", and "provide evidence … substantiating the likely nature or magnitude of the costs that
would be associated with the proposed altern ative, as compared to the current system".
1234
As noted, the complainants put forward cost estimates that would only partially cover the
suggested alternative 1235, along with trace-back systems of other WTO Members of limited
evidentiary value in terms of the implementation and costs of the complainants' third alternative
measure in the United States. 1236 We do not wish to imply that complainants are required in all
cases to describe each and every specific aspect of an alternative measure and provide quantified
cost estimates for each of these. Nevertheless, we do consider that adequate identification of
alternative measures requires more precision than the sometimes vague and in some respects
incomplete description of the implementation and ultimate magnitude of the associate costs
provided by the complainants in this case.
7.557. We therefore find that the complainants have not made a prima facie case that the trace-
back system proposed as their third alternative measure is reasonably available for the purposes
of their claims under Article 2.2 of the TBT Agreement.
7.6.5.4.3 Whether the third alternative me asure is less trade restrictive than the
amended COOL measure
7.558. Apart from reasonable availability, the parties also presented views as to the relationship
between the costs of trace-back and the relative tr ade-restrictiveness of the third alternative. For
example, Canada contends that "[a] technical regulation that increases compliance costs in a
non-discriminatory manner, but does not otherwise modify the conditions of competition to the
detriment of imported products may nevertheless be 'trade-restrictive' if the cost increase has the

1232 Appellate Body Report, Brazil – Retreaded Tyres, para. 156 (quoting Appellate Body Report, US –
Gambling, para. 308). While these statements were made in the context of necessity under Article XX of the
GATT 1994 and Article XIV of the GATS, we find them instructive for whether a technical regulation is "more
trade-restrictive than necessary to fulfil a legitimate objective" under the TBT Agreement. In the context of
Article 2.2 of the TBT Agreement, the Appellate Body recalled its own precedent that "in order to establish
'necessity' in the context of Article XX of the GATT 1994 and Article XIV of the GATS, a comparison of a
measure found to be inconsistent and reasonably available less trade-restrictive alternatives should be
undertaken." Appellate Body Report, US – Tuna II (Mexico), footnote 645 (citing as an example Appellate Body
Report, Korea – Various Measures on Beef, para. 166).
1233 Appellate Body Reports, EC – Seal Products, para. 5.277.
1234 Appellate Body Report, China – Publications and Audiovisual Products, paras. 327-328.
1235 See section 7.6.5.4.1.1 above.
1236 It is also unclear how much more costly trace-back would be for cattle and beef as compared to
hogs and pork. It has been noted that "the cattle industry is expected to bear the brunt of the costs of
implementing a national ID program, in large part because each individual animal will have to be tagged,
unlike in the large, vertically integrated pork and poultry industries, where animals are usually raised and
moved in lots". Exhibit CDA-92, pp. 10-11. See also Exhibits CDA-86, p. 33; CDA-89 and MEX-37, p. 7.
WT/DS384/RW • WT/DS386/RW

effect of reducing trade flows or reducing pr ices of both imported and domestic products." 1237
Likewise, according to Mexico, "the costs of compliance with a technical regulation may be a factor
in the assessment of trade-restrictiveness of the measure at issue. For example, the cost of
compliance may be very high, upsetting competitive opportunities available to imported
products."
1238 The United States emphasizes the focus on trade-restrictiveness under Article 2.2
and contends that the "complainants would have to establish a causal nexus between a change in
costs on the U.S. industry and a change in market access for Canadian and Mexican
producers."
1239
7.559. In this case, the complainants have not demonstrated that trace-back – including the
various possible costs of animal identification, me at traceability, and eventual recordkeeping and
verification aspects – would be less trade restrictiv e based purely on the alleged even distribution
of costs.1240
7.560. We therefore find that the complainants have not made a prima facie case that a trace-
back system for all US-slaughtered cattle and swine would be less trade restrictive than the
amended COOL measure. Given the complainants' insufficient description of their third alternative
and the above limitations of their evidence put forward on its costs, we need not address the
parties' disagreement on the specific relationship of costs and trade-restrictiveness under
Article 2.2 of the TBT Agreement.

1237 Canada's comments on the United States' response to Panel question No. 39, para. 55. Canada
elsewhere refers to "the costs that a measure entails for market participants, in the sense of the losses that
the measure causes them." Canada's response to Panel question No. 39, para. 80.
1238 Mexico's response to Panel question No. 39, para. 82.
1239 United States' response to Panel question No. 39, para. 115.
The European Union states that, with respect to trade-restrictiveness, "one question that arises is
whether one is looking only at the absolute impact of a regulation on imports, or also at its relative impact on
imported and domestic products. The point may be significant in this case because Canada and Mexico appear
to argue that there is an alternative measure (the third alternative) that is generally overall more costly, but
preferable in the sense that the costs would be equally distributed amongst domestic and imported products."
European Union's third-party submission, para. 110 (emphasis original).
Korea submits that "the ordinary meaning of trade-restrictiveness would be that the flow of goods and
services between national borders is constrained. Considering the additional costs and administrative burden
incurred by the trace-back system, one would tend to conclude that the alternative measure would constrain
the flow of the goods in dispute. … If the trade-back system incurring additional costs and administrative
burden unnecessarily requires more information than the policy objective of the COOL requirements pursues,
Korea considers that the trace-back system should not be regarded as a reasonably available alternative
measure." Korea's third-party submission, paras. 10 and 12.
In the view of Japan, "costs can be a relevant factor in the assessment under Article 2.2 and that cost
information could constitute probative evidence of trade restrictiveness. Costs can reflect the regulatory burden
imposed by the challenged measure on imports. In some cases, costs can help estimate the magnitude of the
impact. Furthermore, costs can provide an objective basis to compare the regulatory burden imposed by the
challenged measure with the regulatory burden that would be imposed by reasonably available alternative
measures identified by the complaining party. At the same time, costs should not be dispositive." Japan's
response to Panel question No. 39.
1240 For example, Canada argues that this "could not possibly entail costs that would have a greater
impact" and "it would create a level playing field". Canada's second written submission, para. 112. Canada also
contends that "[a] relevant consideration in that [Sumner] analysis is the fact that, under any one of the
alternative measures Canada has proposed, the costs of complying with the measure would be borne by all
market participants. Any cost increase associated with those tasks would not disproportionately affect imported
livestock." Canada's comments on the United States' response to Panel question No. 39, para. 54. Mexico
submits that "if there were trace-back to the originating farm, there would likely be no incentive to exclude
imported Mexican cattle or shift the cost of compliance solely to Mexican animals. This is because all farmers
would be treated the same and it would be immaterial where they were located. Because U.S. beef processors
would still have to trace U.S. cattle to individual farms, there would be no cost saving associated with
excluding Mexican cattle. Thus, the economic incentive to discriminate against Mexican cattle would likely be
eliminated." Mexico's first written submission, para.204. We note that Canada expressly recognizes that "there
might be some contraction in the U.S. industry under a trace-back system as a result of a possible reduction in
consumer demand." Canada's second written submission, para. 136. See also Hayes and Meyer paper, p. 12
(explaining the reduction of consumer purchases of pork in response to increased production costs and prices).
WT/DS384/RW • WT/DS386/RW

7.6.5.4.4 Whether the third alternative meas ure would make an equivalent contribution
to the relevant legitimate objective
7.561. In the original dispute, the Appellate Body understood the participants "to accept that a
trace-back system could require the provision of consumer information on the country(ies) where
livestock were born, raised, and slaughtered, or of even more detailed information, such as the
specific location of individual production steps within a country." 1241 The complainants put forward
arguments to similar effect in this compliance dispute.1242
7.562. The capability of the proposed trace-back system to fulfil the relevant objective would
largely depend on the system adopted, subject to what may be reasonably available and
technically feasible. We consider this analogous to the alternative measure assessed by the panel
in EC – Seal Products , for which there was found to be an "inextricable link between the
contribution of the alternative measure to the objective and the feasibility of its
implementation".
1243 Thus, while a trace-back system may provide "consumer information on the
country(ies) where livestock were born, raised, and slaughtered, or of even more detailed
information"1244, the actual contribution of trace-back to the relevant objective would be "merely
theoretical"1245 until the alternative measure is adequately identified and the complainants
demonstrate its reasonable availability.
7.563. The insufficiency of the complainants' evidence and arguments as to the implementation of
the third alternative impedes our assessment of its provision of consumer information. In any
event, we are not required
1246 to assess the contribution of the third alternative measure to the
relevant objective due to the complainants' failure to meet their prima facie b u r d e n a s t o
reasonable availability and trade-restrictiveness.
7.6.5.4.5 Conclusion on the third alternative measure
7.564. We have found that the complainants have not provided a sufficient explanation of how
their third alternative measure would be implemented. This lack of adequate identification of the
third alternative measure prevents an assessment of the required elements of this alternative and
its comparison with the amended COOL measur e under Article 2.2 of the TBT Agreement.
Accordingly, we find that the complainants have not made a prima facie case that the third
alternative measure is reasonably available an d less trade restrictive than the amended COOL
measure. For these reasons, we are neither able nor required to find whether it would contribute
to fulfilment of the relevant objective to an equivalent degree.
7.6.5.5 Fourth alternative measure
7.565. The fourth alternative measure would pr escribe that muscle cuts from US-slaughtered
animals
1247 carry labels indicating the place of birth, raising, and slaughter according to
"states and/or province(s)"1248 – in addition to the country designations required by the amended
COOL measure. Relying on the amended COOL measure's abbreviations1249, Labels A-C could read,
for instance, as follows1250:

1243 Panel Reports, EC – Seal Products, para. 7.485. See also Appellate Body Reports, EC – Seal
Products, para. 5.267. The panel also stated that "the degree of contribution achieved by the alternative
measure … depend[ed] on the reasonable availability of satisfying adequate … standards … as well as the
capability of accurately distinguishing the resulting products for placement on the … market." Panel Reports, EC
– Seal Products, para. 7.481.
1244 Appellate Body Reports, US – COOL, para. 490.
1245 See para. 7.555 above.
1246 See para. 7.491 above.
1247 According to the complainants, their alternatives would not cover ground meat or muscle cuts from
foreign-slaughtered animals, and would not change the amended COOL measure's Labels D and E. See
Canada's and Mexico's responses to Panel questions Nos. 44 and 47.
1248 Canada's second written submission, para. 138; Mexico's response to Panel question No. 71.
1249 According to the amended COOL measure, "[a]bbreviations may be used for state, regional, or
locality label designations for these commodities whether domestically harvested or imported using official
WT/DS384/RW • WT/DS386/RW

7.566. According to the complainants
1251, the labels could also show only one state or province for
the production step of raising: for instance, the last state or province in which raising took place
(i.e. where the animals were "finished" before slaughter).
7.567. As a further flexibility, according to Canada, the United States could limit the labelling
requirements to country designations identica l to those under the amended COOL measure.
However, market participants would nevertheless have to be able to demonstrate, if audited, that
a muscle cut was derived from an animal that was born in a specific state/province, raised in a
specific state/province, and slaughtered in specific state/province.1252
7.568. According to the complainants, a key element of the fourth alternative measure would be
to eliminate segregation on a country basis. 1253 Instead, segregation would be required on a more
detailed state/province level.1254 For this, the fourth alternative could maintain the amended COOL
measure's recordkeeping requirements and rely on records kept under the Interstate Livestock
Traceability Rule.1255 Verifying the designation of a state or province in which a production step
took place could be done through the same audi t and verification system of the amended COOL
measure.1256
7.569. As an alternative to segregation on a state/province basis for all movements of animals
(and reliance on the Interstate Livestock Traceability Rule), a national identification and
traceability system, such as the United States' abandoned NAIS, could be used on a mandatory
basis.
1257
7.6.5.5.1 Mexico's endorsement of the fourth alternative measure
7.570. The fourth alternative measure was first proposed by Canada in its second written
submission.1258 Mexico endorsed it later in the proceedings, first during the substantive meeting
with the Panel1259, and again in its responses to the Panel.1260
7.571. The United States considers Mexico's endorsement to have come too late, and contends
that it has not had sufficient time to respond to Mexico's claims under the fourth alternative. 1261
According to the United States, our Working Procedures, read in conjunction with Articles 9 and
12.4 of the DSU, preclude us from admitting Mexico's endorsement of Canada's fourth alternative
measure and the evidence submitted in support.1262

7.572. As both the United States and Mexico note, each complainant must individually and
separately meet its burden of proof for each of its claims. 1263 This follows also from Article 9 of the
DSU, according to which, even when a single panel is established for the examination of multiple
complaints on the same matter, such a panel must "organize its examination and present its
findings to the DSB in such a manner that the rights which the parties to the dispute would have
enjoyed had separate panels examined the complaints are in no way impaired."
1264
7.573. As a factual matter, Mexico endorsed Canada's fourth alternative measure for the first time
in its opening oral statement at the Panel's substantive meeting on the 18 February 2014. 1265
After the meeting, the parties were asked to prov ide written answers to a set of questions posed
by the Panel. One of those written questions invited Mexico to confirm whether it was also
proposing Canada's fourth alternative measure, and if yes to provide evidence in support of its
prima facie case on the matter.
1266 In accordance with the timetable adopted by the Panel,
Mexico responded to the Panel's written questions on 7 March 2014, confirming its endorsement of
Canada's fourth alternative measure. 1267 Prior to receiving these answers, in a communication
dated 3 March 2014, the United States requested an additional week for submitting comments on
the complainants' and third parties' responses to the Panel's questions. Having considered the
parties' comments on the United States' request for extension, on 5 March 2014 the Panel revised
the timetable to grant the additional week requested by the United States. 1268 I n l i n e w i t h t h i s
revised timetable, on 21 March 2014 the parties submitted their comments on each other's
responses.
7.574. Article 12.4 of the DSU provides that "[in] determining the timetable for the panel process,
the panel shall provide sufficient time for the part ies to the dispute to prepare their submissions".
In the context of the fourth alternative measur e, meeting this requirement entailed giving the
United States sufficient time to respond to Mexico's endorsement at the meeting as well as its
relevant responses to the Panel's questions following the meeting. As indicated by the
Appellate Body in Australia – Salmon , "[a] fundamental tenet of due process is that a party be
provided with an opportunity to respond to claims made against it".
1269
7.575. More generally, according to the Appellate Body:
[d]ue process is a fundamental principle of WTO dispute settlement.1270 It informs and
finds reflection in the provisions of the DSU. 1271 In conducting an objective

1263 Mexico's response to Panel question No. 35, para. 59; United States' response to Panel question
No. 35, and comments on Mexico's response to Panel question No. 35. Mexico seems to suggest otherwise,
however, when it states that "Mexico and Canada […] have jointly presented a prima facie case with respect to
the four alternative measures that have been proposed." Mexico's opening statement at the meeting with the
Panel, para. 55.
1264 Article 9.2 of the DSU. We make this observation without prejudice to our comments above with
respect to procedural aspects of the establishment of this compliance Panel. See section 1.3.4 above.
1265 This endorsement was not solicited by any of the advanced questions sent to the parties before the
substantive meeting.
1266 Panel question No. 72 asked Mexico: "Do you propose the fourth alternative measure put forward by
Canada in its Second Written Submission? If yes, please elaborate how the Article 2.2 test should be applied to
this alternative, and please also answer Question 71." Question No. 71 addressed Canada in the following
terms: "How would the fourth suggested alternative measure affect segregation, recordkeeping, and labelling?
Please respond to the US arguments about frequent interstate movements and the concentration of Canadian
cattle production. (United States' Second Written Submission, paras. 161-162)."
1267 Mexico's response to Panel questions Nos. 71-72.
1268 The Appellate Body has held that panels enjoy a margin of discretion to deal with situations that are
not explicitly regulated. According to the Appellate Body, "the DSU, and in particular its Appendix 3, leave
panels a margin of discretion to deal, always in accordance with due process, with specific situations that may
arise in a particular case and that are not explicitly regulated." Appellate Body Report, EC – Hormones ,
footnote 138.
1269 Appellate Body Report, Australia – Salmon, para. 278.
1270 (footnote original) The Appellate Body has held that "the protection of due process is an essential
feature of a rules-based system of adjudication, such as that established under the DSU", and that "due
process is fundamental to ensuring a fair and orderly conduct of dispute settlement proceedings".
(Appellate Body Reports, Canada – Continued Suspension / US – Continued Suspension, para. 433; and
Appellate Body Report, Thailand – H-Beams, para. 88, respectively. See also Appellate Body Report, Chile –
Price Band System, para. 176).
WT/DS384/RW • WT/DS386/RW

assessment of a matter, a panel is "bound to ensure that due process is
respected".1272 Due process is intrinsically connected to notions of fairness,
impartiality, and the rights of parties to be heard and to be afforded an adequate
opportunity to pursue their claims, make out their defences, and establish the facts in
the context of proceedings conducted in a balanced and orderly manner, according to
established rules. The protection of due process is thus a crucial means of
guaranteeing the legitimacy and efficacy of a rules-based system of adjudication.
1273
7.576. The "fair", "impartial", "balanced and or derly" nature of due process entails that due
process applies to all parties in a dispute equally. 1274 In this sense, complainants' right "to be
afforded an adequate opportunity to pursue their claims" and respondents' right "to be afforded an
adequate opportunity … to make out their defences" are two sides of the same coin: the right to
be heard. Whereas the United States is undeniably entitled to an adequate opportunity to respond
to claims made against it, it is equally imperative that Mexico have an adequate opportunity to
make its claims. The same applies generally to arguments and evidence advanced by the parties.
7.577. That balance is also reflected in our Working Procedures. Paragraph 7 thereof provides that
"each party shall submit all factual evidence to the Panel no later than during the substantive
meeting, except with respect to evidence necessary for purposes of rebuttal, answers to questions
or comments on answers provided by the other party."
1275 Moreover, "[e]xceptions to this
procedure shall be granted upon showing good caus e", provided that the Panel "shall accord the
other party a period of time for comment, as a ppropriate, on any new factual evidence submitted
after the substantive meeting."1276
7.578. Mexico endorsed the fourth alternative measure at the Panel's single substantive meeting
with the parties. It would have been preferable for Mexico to do this at an earlier stage, and not
following the two exchanges of written submission s among the parties. Likewise, it would have
been preferable for Canada to propose the fo urth alternative measure in its first written
submission. Introducing and clarifying the altern ative measures at the earliest possible stage
would have contributed to more efficient panel proceedings – both organizationally, and in terms
of the other parties' and third parties' right to be heard more fully with regard to the fourth
alternative measure.
1277
7.579. Canada, the other complainant in this dispute, proposed the fourth alternative measure
only in its second written submission, with the result that the opening oral statement at the
substantive meeting was Mexico's first opportunity to endorse Canada's newly introduced
alternative measure. The terms of the Working Procedures did not preclude Mexico from endorsing
Canada's fourth alternative measure in the opening oral statement at the Panel hearing.1278

1277 In Thailand – Cigarettes (Philippines), the Appellate Body "recalled that panel proceedings consist of
two main stages, the first of which involves each party setting out its 'case in chief, including a full
presentation of the facts on the basis of submission of supporting evidence', and the second designed to permit
the rebuttal by each party of the arguments and evidence submitted by the other parties. Nonetheless, the
submission of evidence may not always fall neatly into one or the other of these categories, in particular when
panels themselves, in the exercise of their fact finding authority, seek to pursue specific lines of inquiry in their
questioning of the parties. In this respect, we wish to reiterate that due process will best be served by working
procedures that provide 'for appropriate factual discovery at an early stage in panel proceedings'."

1278 According to the Appellate Body, "when the particular circumstances of specific disputes present

to deal with such situations." Appellate Body Report, Thailand – Cigarettes (Philippines), para. 149

7.580. Once a claim or argument is properly put before it, a panel has broad powers of
investigation and discovery in order to make an objective assessment of the matter before it. 1279
Following Mexico's endorsement of the Canada's fourth alternative measure at the substantive
meeting, the Panel availed itself of these faculties to invite the complainants to submit further
arguments and factual evidence with respect to th e fourth alternative measure. By the terms of
paragraph 7 of the Working Procedures, Mexico then had the right to submit arguments and
evidence in response to these questions from the Panel.
7.581. Turning to the United States, we gran ted the extension for the period of comments
requested by the United States. As a result, the United States had in total four and a half weeks to
prepare its response to Mexico's endorsement of the fourth alternative measure, and two weeks to
comment on Mexico's responses to the Panel's questions, including with regard to the fourth
alternative measure. By way of comparison, the Un ited States had less than four weeks to submit
its first written submission following receipt of the complainants' first written submissions.
Likewise, the parties had less than four weeks to submit their second written submissions setting
out rebuttals on the totality of the claims.
7.582. We recognize that during the two and a half weeks between Mexico's endorsement of the
fourth alternative measure and its responses to the Panel's questions, the United States could not
have anticipated the arguments and evidence that Mexico might put forward in its responses in
relation to the fourth alternative measure. Yet, Mexico gave clear indications at the substantive
meeting that it was proposing the same alternative that Canada had raised in its second written
submission. In its opening statement, Mexico stated that it "agrees with Canada's submissions on
this alternative and the fact it (i) would provide a greater contribution to the objective than the
Amended COOL Measure, (ii) would be less trade restrictive and (iii) is reasonably available."
1280
In addition, Mexico referenced "the evidence and arguments" of Canada in this regard. 1281 In its
comments on Mexico's responses to the Panel, the United States noted that it "has had time to
evaluate Canada's fourth alternative." 1282 We see no reason why the same does not apply to
Mexico's endorsement of Canada's evidence and arguments for the fourth alternative measure at
the hearing, given that at that point Mexico advanced no additional argument and evidence to that
provided by Canada.
7.583. We also recognize that, as the United States points out 1283, a response to the same claim
made by separate complainants may be different – depending, for instance, on any differences
between the complainants and their relevant argume nts and evidence. In fact, this was one of the
considerations we took into account for extending the period of time for parties to comment on
each other's responses. The extension we grante d corresponds exactly to the period of time
requested by the United States following Mexico's responses to the Panel's relevant questions.
7.584. In light of the above, we do not consider that Mexico's endorsement of Canada's fourth
alternative measure came too late in these proceedings. Nor do we consider that the
United States' rights of due process rights have been affected as a result. Accordingly, we admit
Mexico's endorsement of the fourth alternative measure and the arguments and evidence
submitted in support of its claims under that al ternative measure. Under the circumstances, we
proceed to examine whether Canada and Mexico make a prima facie case in relation to the fourth
alternative measure.
7.6.5.5.2 The implementation of the fourth alternative measure
7.585. As noted, in comparing the challenged measure with a proposed alternative measure under
Article 2.2 of the TBT Agreement, "it will be relevant to consider whether the proposed alternative
is less trade restrictive; whether it would make an equivalent contribution to the relevant

legitimate objective, taking account of the risks non-fulfilment would create; and whether it is
reasonably available."1284
7.586. Before reviewing these aspects of the fourth alternative measure, we first address how this
proposed measure would be implemented according to the complainants. As noted, adequately
explaining how an alternative measure would be implemented is an essential part of the
complainants' burden to identify an alternative measure that is not limited to a "concept[]" but
entails an "actual, concrete proposal[]".
1285 Having a basic understanding of how an alternative
measure would be implemented is a prerequisite for comparing this alternative with the challenged
measure.1286
7.587. The complainants' fourth alternative measure would prescribe that origin information be
provided at retail – or at least maintained and transmitted in the supply chain 1287 – according to
states/provinces, and not just by countries of origin. As noted, the complainants suggest two
approaches to achieve this: (i) trace-back; and (ii) segregation and recordkeeping.
7.6.5.5.2.1 Trace-back
7.588. According to the complainants, the first appr oach would entail a national identification and
traceability system, such as the United States' abandoned NAIS, applied on a mandatory basis.1288
7.589. We have already addressed the shortcomings of the complainants' references to the NAIS
for describing the operation of trace-back under the third alternative measure.1289 In the context of
the fourth alternative measure, the complainan ts refer to the NAIS without adducing any
arguments that would affect the relevance of thes e shortcomings for a trace-back approach under
the fourth alternative measure. Further, the co mplainants do not explain how NAIS should be
implemented differently to provide origin information according to states/provinces.
7.590. In any event, as Canada recognizes, the NAIS could serve as a model for only "the first
stage of a trace-back system" under the fourth alternative measure. 1290 As regards the second
stage, Canada describes a single aspect of trace-back at the slaughterhouse. Canada argues that
US slaughterhouses could assemble groups of anim als on a state/province basis in larger groups
than under the third alternative measure. 1291 Thus, according to Canada, trace-back under the
fourth alternative measure would entail lower compliance costs than the third alternative. 1292
Canada makes this argument in response to the United States' contention that state/province
labelling would entail that "each individual head of cattle be tracked as it goes through the
livestock production process"
1293, and thus, like the third alternative measure, the fourth
alternative would also require "the tracking of individual animals." 1294 Mexico advances no
description as to how trace-back could serve for the implementation of the fourth alternative
measure at the second stage, i.e. the killing of th e animal and the division of the carcass into cuts
at the slaughterhouse. Further, the complainants provide no specific argument as to how trace-
back would be implemented in the third stage, i.e. in meat processing and distribution beyond the
slaughterhouse, under the fourth alternative measure.
7.591. In sum, the complainants, in particular Mexico, provide very limited or no specific
description of how a trace-back approach would serve to implement their fourth alternative

measure. For the first stage, the complainants have referenced an abandoned US measure (NAIS),
without addressing the shortcomings of the NAIS fo r describing the operation of trace-back at that
stage. We lack an adequate explanation from the complainants for the second and third stages of
trace-back. Yet, Canada considers the second stage to be the most costly.
1295
Further, as explained for the third alternative measure, all three stages of trace-back are
necessary to ensure origin information at the point of retail sale. 1296 To the extent relevant,
we also note that the complainants provide no explanation on how they could supply relevant
state/province origin information compatible with a US trace-back system specifically for the fourth
alternative measure.
7.592. Accordingly, we find that the complainants have not provided a sufficient explanation of
how their fourth alternative measure would be implemented using a trace-back system.
7.6.5.5.2.2 Segregation and recordkeeping
7.593. According to the complainants, the second approach to implement the fourth alternative
measure would entail segregation on a more detailed state/province level. 1297 To substantiate
origin claims, the amended COOL measure's reco rdkeeping requirements could be maintained,
relying also on records kept under the Interstate Livestock Traceability Rule.1298
7.594. The complainants refer specifically to th e Interstate Livestock Tr aceability Rule for its
recordkeeping requirements on interstate movements. 1299 According to Canada, if "further
developed to facilitate the verification of origin designations by state", the "records kept for …
complying with the [Interstate Livestock Traceabi lity Rule] could be used to verify [origin]
designations under the proposed [fourth] alternative measure." 1300 At a later point, Canada
appears to adjust this argument by stating that the "United States could rely on the segregation of
animals on a state/province basis and on documents generated pursuant to, or required under,
[the Interstate Livestock Traceability Rule], combined with requirements for producer's affidavits
for elements that are not currently fully covered under that Rule."
1301
7.595. Canada and the United States contest the exact scope of the current exemptions from the
Interstate Livestock Traceability Rule for inter-state livestock movements, including from its
record-keeping rules, and whether these exemptio ns would be addressed in future rulemaking. 1302
In any event, the United States argues that records kept pursuant to the Interstate Livestock
Traceability Rule do not accompany the animal.
1303 Canada responds that all cattle moving
interstate and destined for slaughter, irrespective of age, must be accompanied by an owner-
shipper statement, which is subject to the recordkeeping requirements.1304
7.596. We noted above the shortcomings of the complainants' references to the Interstate
Livestock Traceability Rule for describing the implementation or essential features of the third
alternative measure.1305 In the context of the fourth alternative measure, the complainants refer
to this Rule without adducing arguments that would clarify its requirements or relevance to an
alternative providing state/province designations on retail muscle cuts.
7.597. In particular, only Canada provides a limited explanation of how the Interstate Livestock
Traceability Rule might apply under the fourth alternative measure. We understand Canada to
advance a combination of owner-shipper statements under the Interstate Livestock Traceability
Rule and producer's affidavits for elements that are not currently fully covered under that Rule.
Nevertheless, Canada recognizes that currently "there is no requirement to record the

identification number of [currently exempt ed] cattle on the owner-shipper statement". 1306
Accordingly, it is unclear how owner-shipper statements could be used to convey origin
information on specific animals, and consequently what elements would not be fully covered and
thus need to be substantiated by producers' affidavits for the purposes of the fourth alternative
measure. In any event, the Interstate Livestock Traceability Rule deals with traceability of
interstate animal movements.
1307 Thus, it is limited to the life of the animal.
7.598. The complainants advance limited arguments on how recordkeeping would be implemented
under the fourth alternative measure from the anim al's slaughter to the meat retail stage. As a
general point, the complainants assert that the re cordkeeping requirements "could be the same as
those under the amended COOL measure".1308 They add that verifying the designation of a state or
province in which a production step took place could be done through the same audit and
verification system of the amended COOL measure. 1309 As regards applying the fourth alternative
measure specifically at the slaughterhouse, according to Canada, "U.S. slaughterhouses could
continue to rely on, for instance, health papers or producer affidavits, including for animals born
and/or raised in Canada."
1310
7.599. However, the complainants do not specify how the amended COOL measure's
recordkeeping requirements would be implemente d to maintain and transmit the more detailed
origin information under the complainants' fourth alternative measure. For instance, despite its
assertions, Canada recognizes that "[t]he presence of an ear tag from Canada would no longer be
sufficient because information on the province would be necessary."
1311 The United States agrees,
and points out that " Canadian entities would need to maintain those records with each sale of the
animal, including the sale of the animal to the U.S. slaughterhouse." 1312 As a result, it is not clear,
for instance, what records would be necessary to allow US slaughterhouses to initiate the origin
claim of foreign-origin animals, and whether relying on the amended COOL measure's
recordkeeping requirements would be sufficient for the complainants' fourth alternative measure.
7.600. Finally, we note that the complainants ar gue that the fourth alternative measure is not
merely theoretical because the amended COOL measure already provides that state, regional, or
locality label designations may be used in lieu of country of origin labelling for perishable
agricultural commodities.
1313 To the extent the complainants are advancing this argument to
describe how their fourth alternative measure could be implemented, we consider its relevance to
be limited. In fact, Canada recognizes that this voluntary rule does not apply to meat, and it is not
aware of US retailers having used this rule for the products covered by the rule.
1314
7.601. In light of the above, we find that the complainants have not sufficiently explained how
their fourth alternative measure would be im plemented by means of either trace-back,
or recordkeeping and segregation.
7.6.5.5.2.3 Conclusion on the implementation of the fourth alternative measure
7.602. As noted, the complainants' limited explanat ions do not provide a sufficient description of
how their fourth alternative measure would be implemented in the United States. As noted 1315, an
adequate identification of an alternative measur e is a prerequisite for assessing its reasonable
availability and for comparing its trade-restrictiveness and degree of contribution with the

challenged measure. Accordingly, we are not in a position to carry out the comparative analysis
with regard to the fourth alternative measure.
7.6.5.5.3 Costs of the fourth alternative measure
7.603. In light of the parties' arguments in this dispute, we have noted that the costs of an
alternative measure may have implications for both its reasonable availability and its trade-
restrictiveness.
1316 We have also noted that the complainants have the initial burden to make a
prima facie case in this regard.1317 The complainants have adduced only limited arguments on the
costs of the fourth alternative.
7.604. As regards implementing the fourth alternative measure by means of trace-back, only
Canada has adduced argument as to the specific costs of this approach. 1318 This argument is
limited to the NAIS and, hence, to only the first stage of trace-back.
7.605. As regards implementing the fourth alte rnative measure by means of recordkeeping and
segregation, Canada relies on "the same mechanisms and logic that prevail under the amended
COOL measure, except that the mechanisms and logic apply one level down (states and provinces,
as opposed to countries)."
1319 Accordingly, based on the logic set out above 1320, the fourth
alternative measure would involve increased segregation and higher overall segregation costs than
the amended COOL measure.
7.606. With the increase of segregation, the overall recordkeeping burden and costs would also be
higher under the fourth alternative measure th an under the amended COOL measure. As the
United States explains, "while the type of docu ments may be the same, the information provided
in these documents, the entity maintaining those documents, and the sheer number of documents,
would be quite different (and more burdensome) under the fourth alternative than it is under the
amended COOL measure."1321
7.607. Thus, implementing the fourth alternat ive measure by recordkeeping and segregation
could entail higher overall segregation and record keeping costs than the amended COOL measure.
Indeed, in response to the United States' suggestion that Canada may voluntarily provide province
designations
1322, Canada recognizes that this would create a "further … burden" for Canada. 1323
Instead of specifying the overall costs, the co mplainants focus on whether the segregation and
recordkeeping costs of their fourth alternative would be borne in a discriminatory fashion. Yet, the
complainants recognize that there might be an absolute cost level which might result in trade-
restrictiveness even with a non-discriminatory distribution of costs.
1324
7.608. The complainants' limited arguments on the costs of the fourth alternative measure 1325
reinforce our conclusion that the complainants have not adequately explained how the fourth

1323 Canada's response to Panel question No. 73.
1324 See section 7.6.5.1.3 above. In regard to this point, Canada advances that "state and/or province
designations would certainly not entail additional costs in the minimum amount of $608 per head of cattle and
$116 per hog." Canada's second written submission, para. 146 (footnote omitted). However, we have found
that we cannot draw any inferences from the studies advanced by the complainants as to whether the implied
additional costs of any non-discriminatory alternative measure implemented in the United States are effectively
lower than the hypothetical and simulated figures. See 7.6.5.1.3 above.
1325 Canada contests the relevance of the United States' argument that there could be more animal
concentration and less animal movements in Canada than in the United States. However, Canada does not
contest this argument as such. As the United States points out, this might have implications for the overall
costs of the fourth alternative in the United States and Canada. Hence, it might also impact how these costs
would be distributed among the United States and Canada. To reduce the overall US costs of the fourth
alternative measure, Canada mentions that only the last state/province of raising should be shown on the
label. However, Canada does not address the implication of this flexibility for the distribution of costs among
WT/DS384/RW • WT/DS386/RW

alternative measure would be implemented so as to enable a meaningful comparison with the
amended COOL measure.
7.6.5.5.4 Conclusion on the fourth alternative measure
7.609. The complainants failed to provide an adeq uate explanation of how their fourth alternative
measure would be implemented. In addition, th e complainants have not advanced sufficient
arguments on the costs of the fourth alternative measure to enable us to review the fourth
alternative measure's reasonable availability and trade-restrictiveness.
7.610. Consequently, we find that the complainants have not made a prima facie case that the
fourth alternative measure is reasonably available and less trade restrictive than the amended
COOL measure. In light of this, we do not find it necessary to assess whether the fourth
alternative measure would make a contribution to the objective of providing consumer information
on origin at least equivalent to the amended COOL measure's actual degree of contribution to the
same objective.
7.6.6 Conclusion on Article 2.2 of the TBT Agreement
7.611. We have found that the amended COOL measure pursues a legitimate objective and
contributes to the fulfilment of this objective to a considerable but necessarily partial degree.
Further, we have found that the amended COOL measure has increased the "considerable degree
o f t r a d e - r e s t r i c t i v e n e s s " f o u n d b y t h e A p p e l l a t e B o d y i n t h e o r i g i n a l d i s p u t e . W e h a v e a l s o
established the nature of the risks of not fulfilling the amended COOL measure's objective as well
as the consequences of non-fulfilment; however, we have been unable to ascertain the gravity of
these consequences.
7.612. Following this relational analysis, we conducted a comparative analysis of the
complainants' suggested four alternative measures, and found that the complainants did not make
a prima facie case that any of these alternatives demonstrate that the amended COOL measure is
more trade restrictive than necessary within the meaning of Article 2.2 of the TBT Agreement.
7.613. In light of the above, we conclude that the complainants have not made a prima facie case
that the amended COOL measure violates Article 2.2 of the TBT Agreement.
7.614. In concluding, we recall our earlier finding that providing consumer information on origin is
a legitimate objective. A Member is therefore free to adopt technical regulations consistent with its
WTO obligations to pursue this objective. Further, in making our findings, we do not mean to imply
that there is no practical, WTO-consistent way for Members to pursue the above legitimate
objective. In the context of Article 2.2 of the TBT Agreement, we have not made a determination
whether or not the complainants' four alternative measures fulfil the three elements
1326 of the
legal test of the comparative analysis. Rather, our comparative analysis is focused on whether the
complainants have made a prima facie case, and concludes that the complainants have not done
so in the context of our comparative analysis. In this context, we consider that some form of
trace-back could require the provision of consumer information on the country(ies) where livestock
were born, raised, and slaughtered, or of even more detailed information, such as the specific
location of individual production steps within a country.
1327
7.615. By virtue of our terms of reference, ou r comparative analysis under Article 2.2 of the
TBT Agreement is confined to the four alternative measures as identified by the complainants.
We have not reviewed other possible variations of these alternatives; nor have we considered
general techniques to convey country of origin information to consumers in the abstract. We do
not wish to exclude that some variation of the alternatives suggested by the complainants might
provide a WTO-consistent solution for pursuing the legitimate objective of providing consumer
information on origin.

WT/DS384/RW • WT/DS386/RW

7.616. In sum, our findings of violation relate specifically to the discriminatory nature of the
amended COOL measure with respect to imported livestock. In our view, attaining a non-
discriminatory solution might well be achieved through further consultations among the parties.
7.7 Article III:4 of the GATT 1994
7.617. Article III:4 of the GATT 1994 provides in relevant part:
The products of the territory of any contracting party imported into the territory of
any other contracting party shall be accorded treatment no less favourable than that
accorded to like products of national origin in respect of all laws, regulations and
requirements affecting their internal sale, offering for sale, purchase, transportation,
distribution or use.
7.618. The complainants argue that the amende d COOL measure violates Article III:4 of the
GATT 1994, and request the Panel to address their claims under Article III:4 irrespective of the
Panel's findings under Article 2.1 of the TBT Agreement.
1328 The United States contends that the
complainants failed to establish the inconsistency of the amended COOL measure with Article III:4
of the GATT 1994.1329
7.7.1 Legal test
7.619. As the Appellate Body has recently conf irmed, there are three elements that must be
demonstrated to establish that a measure is inconsistent with Article III:4: "(i) that the imported
and domestic products are 'like products'; (ii) that the measure at issue is a 'law, regulation, or
requirement affecting the internal sale, offering for sale, purchase, transportation, distribution, or
use' of the products at issue; and (iii) that the treatment accorded to imported products is 'less
favourable' than that accorded to like domestic products."
1330
7.620. The complainants argue, and the United St ates does not contest, that the amended COOL
measure fulfils the first two elements. 1331 At the same time, the parties disagree on the specific
criteria for the "less favourable treatment" elemen t, and on the extent to which it might overlap
with the "less favourable treatment" test under Article 2.1 of the TBT Agreement.1332
7.621. The United States argues in this regard that detrimental impact on competitive conditions
"is not enough" for establishing less favourable treatment under Article III:4. 1333 It contends that

1329 See United States' first written submission, Section III.C.

para. 133). See also Canada's first written submission, para. 91; and Mexico's first written submission,
para. 215. In its arguments, the United States focuses on the "less favourable treatment" of Article III:4 of the
GATT 1994, and does not call into question the relevance of the other two elements of the Article III:4 legal
test.
1331 For the "like products" element, see Canada's first written submission, para. 92; and Mexico's first
written submission, para. 217. For the "measure at issue" element, see Canada's first written submission,
1332 See Canada's first written submission, para. 94; Mexico's first written submission, paras. 225-229;

Mexico's second written submission, paras. 73-80; and United States' second written submission, paras. 81-94.
As regards the third parties, the European Union agrees with the United States, and contends that the
analysis under Article III:4 of the GATT 1994 "includes a consideration of not only the impact of the measure
on competitive opportunities for imports, but also a consideration of whether the origin neutral objective or
regulatory distinction is legitimate and even-handed". European Union's third-party submission, para. 140.
See also European Union's third-party statement, paras. 36-37 and 44-45. Conversely, New Zealand supports
the complainants' approach, arguing that the legal test under Article III:4 does not entail "an analysis of
whether the … measure makes distinctions that can be ex plained by factors or circumstances unrelated to the
origin of the imported products". New Zealand's third-party submission, paras. 27-29. Finally, Japan submits
that importing the interpretation of Article 2.1 of the TBT Agreement into Article III:4 of the GATT 1994 "is not
without difficulties", and that introducing flexibility into Article III:4 may render Article XX of the GATT 1994
"meaningless". Japan's third-party statement, paras. 18-19.
1333 United States' first written submission, para. 123.
WT/DS384/RW • WT/DS386/RW

the Panel should additionally assess whether any detrimental impact can be "explained by other
factors or circumstances that do not reflect discrimination".1334
7.622. Canada responds that the United States is trying to "import the legitimate regulatory
distinction component of the TBT Article 2.1 test into the GATT Article III:4 analysis" of less
favourable treatment, without any textual basis. 1335 Mexico adds that, unlike under Article 2.1 of
the TBT Agreement, establishing less favourable treatment in the context of Article III:4 of the
GATT 1994 remains a single-step approach, 1336 and there is "no need to make any additional
determination under Article III:4 on whether the detriment reflects discrimination against like
imported products".1337
7.623. The Appellate Body has recently clarified the meaning of the term "treatment no less
favourable" in Article III:4 of the GATT 1994. In pa rticular, it considered "well established" that
"the term 'treatment no less favourable' requires effective equality of opportunities for imported
products to compete with like domestic products." 1338 The Appellate Body added that "because
Article III:4 is concerned with ensuring effective equality of competitive opportunities for imported
products, a determination of whether imported products are treated less favourably than like
domestic products involves an assessment of the implications of the contested measure for the
equality of competitive conditions between imported and like domestic products."
1339
Thus, according to the Appellate Body, "Article III: 4 permits regulatory distinctions to be drawn
between products, provided that such distinctions do not modify the conditions of competition
between imported and like domestic products."
1340
7.624. On this basis, the Appellate Body concluded:
If the outcome of this assessment is that the measure has a detrimental impact on the
conditions of competition for like imported products, then such detrimental impact will
amount to treatment that is "less favourable" within the meaning of Article III:4 . …
We do not consider … that for the purposes of an analysis under Article III:4, a panel
is required to examine whether the detrimental impact of a measure on competitive
opportunities for like imported products stems exclusively from a legitimate regulatory
distinction.
1341
7.625. We consider the Appellate Body's clarificatio ns in this regard to directly dispose of similar
arguments in this compliance dispute. The Appellate Body unequivocally stated that "the legal
standard for the non-discrimination obligations under Article 2.1 of the TBT Agreement does not
apply equally to claims under Article … III:4 of the GATT 1994."
1342 Accordingly, we reject the
United States' suggestion to address legitimate regulatory distinctions in the context of less
favourable treatment under Article III:4 of the GATT 1994.

1334 United States' first written submission, para. 123 (citing Appellate Body Report, Dominican Republic
– Import and Sale of Cigarettes, para. 96). The United States also argues that "[t]he analysis under
Article III:4 … necessarily entails an ex amination of whether the regulation makes distinctions that could not
be considered even-handed as to the group of 'like' imported products versus the group of 'like' domestic
products, or whether those distinctions are, in fact, even-handed and any detrimental effect can be explained
by factors or circumstances unrelated to the foreign origin of the imported product." See United States' first

7.7.2 Judicial economy
7.626. The complainants request us to address their claims under Article III:4 of the GATT 1994,
and not to exercise judicial economy in this regard. 1343 We recall that panels have full discretion to
exercise judicial economy on a claim 1344 a s l o n g a s t h i s d o e s n o t a m o u n t t o " f a l s e j u d i c i a l
economy".1345
7.627. The original panel held that under Arti cle III:4 of the GATT 1994, "[a]ccording 'treatment
no less favourable' [in the sense of Article III:4] means … according conditions of competition no
less favourable to the imported product than to the like domestic product". 1346 The original panel
applied this reasoning in its analysis of less favourable treatment under Article 2.1 of the
TBT Agreement, and emphasized the close connect ion between Article 2.1 of the TBT Agreement
and Article III:4 of the GATT 1994.
1347 In light of its findings under Article 2.1, the original panel
considered it unnecessary to assess the claims under Article III:4. 1348 Thus, the original panel
equated the less favourable treatment tests under Article 2.1 of the TBT Agreement and
Article III:4 of the GATT 1994.
7.628. Subsequently, in US – Clove Cigarettes the Appellate Body established that the analysis of
less favourable treatment under Article 2.1 of the TBT Agreement entails assessing whether the
detrimental impact on competitive opportunities for imports stems exclusively from legitimate
regulatory distinctions.
1349 The Appellate Body followed this approach in addressing the appeal of
the original panel's Article 2.1 finding in US – COOL.1350
7.629. As noted, the Appellate Body in EC – Seal Products confirmed that the "less favourable
treatment" tests under Article III:4 of the GATT 1994 and Article 2.1 of the TBT Agreement are
different. Therefore, and taking into account the complainants' explicit request to address their
Article III:4 claims1351, we shall not exercise judicial economy. We address the established three
elements of the Article III:4 test.
7.7.3 Likeness
7.630. As we have mentioned above, the complainants argue, and the United States does not
contest, that imported and US cattle and hogs continue to be like products.1352

1343 Canada's first written submission, para. 22; Mexico's first written submission, para. 55.
1344 In India – Patents the Appellate Body established that "[a] panel has the discretion to determine the
claims it must address in order to resolve the dispute between the parties". Appellate Body Report, India –

1345 In Australia – Salmon, the Appellate Body held that the task of a panel is to "address those claims
on which a finding is necessary in order to enable the DSB to make sufficiently precise recommendations and
rulings … 'in order to ensure effective resolution of di sputes'", and cautioned that "provid[ing] only a partial
resolution of the matter at issue would be false judicial economy". Appellate Body Report, Australia – Salmon,
para. 223. In US – Wool Shirts and Blouses, the Appellate Body found that neither Article 11 of the DSU nor
"previous GATT practice require[d] a panel to examine all legal claims made by the complaining party"
(emphasis omitted). The Appellate Body agreed with the practice of previous panels to make "findings only on
those claims that such panels concluded were necessary to resolve the particular matter". Appellate Body

between "less favourable treatment" tests in Article 2.1 of the TBT Agreement and Article III:4 of the
GATT 1994, finding that "relevant guidance for interpreting the term 'treatment no less favourable' in
Article 2.1 may be found in the jurisprudence relating to Article III:4 of the GATT 1994". Appellate Body
Reports, US – COOL, para. 269.
1348 Panel Reports, US – COOL, para. 7.807. Like the original panel, the Appellate Body did not make

7.631. The concept of likeness in Article 2.1 of the TBT Agreement should be read in the context
of Article III:4 of the GATT 1994.1353 In addition, the legal tests for likeness in both Article 2.1 and
Article III:4 concern the determination of the "c ompetitive relationship between and among the
products at issue"1354, and in the context of Article 2.1 of the TBT Agreement we have found that
Canadian cattle and US cattle, and Mexican cattle and US cattle, are like products, and that
Canadian hogs and US hogs are also like products.1355
7.632. In the original dispute, the original panel established that "addressing and indicating
'origin' is the essence and rationale of the [original] COOL measure". 1356 Based on previous
disputes, the original panel recalled that "products that [were] distinguished solely on the basis of
their origin were found to be like products within the meaning of Article III:4".
1357 The original
panel concluded that there was no need to engage in any further analysis to establish the likeness
of the products at issue.1358
7.633. The changes introduced by the 2013 Final Ru le do not affect the rationale of the original
COOL measure to address the origin of the products at issue; the same rationale continues to
apply to the amended COOL measure. The produc ts at issue are also the same, and can be
distinguished solely on the basis of origin. Like the original panel, we consider this sufficient to
establish the likeness of the products at issue.
7.634. Accordingly, we conclude that the products at issue are like products within the meaning of
Article III:4 of the GATT 1994.
7.7.4 Law, regulation, or requirement affe cting the internal sale, offering for sale,
purchase, transportation, distribution, or use of the products at issue
7.635. The complainants allege, and the United States does not contest, that the amended COOL
measure is a "law, regulation, or requirement affecting [the] internal sale, offering for sale,
purchase, transportation, distribution, or use" of the products at issue.
1359
7.636. Based on the text of Article III:4, this element entails two considerations: (i) whether the
measure is a law, regulation, or requirement within the meaning of Article III:4; and (ii) whether
the measure affects the internal sale, offering for sale, purchase, transportation, distribution, or
use of the products at issue.
1360
7.637. We recall that the amended COOL measure consists of a statutory and a regulatory
element.1361 Thus, by virtue of their legal form, these instruments qualify as a law and regulation,
respectively. In addition, we have established that the amended COOL measure is a technical
regulation, in part because of its mandatory nature. 1362 The mandatory nature of the amended
COOL measure confirms that the amended COOL measure falls within "laws, regulations or
requirements" as those terms are used in Article III:4 of the GATT 1994.

7.638. The second part of the test is that the measure "affect[s] … internal sale, offering for sale,
purchase, transportation, distribution, or use" of the products at issue. The Appellate Body
considered the term "affecting" to have a broad scope of application
1364, and qualified it as a
"link between identified types of government action ('laws, regulations and requirements') and
specific transactions, activities and uses relating to products in the marketplace ('internal sale,
offering for sale, purchase, transportation, distribution or use')".1365
7.639. According to Annex 1.1 of the TBT Agreement, a technical regulation is a document which
lays down product characteristics. In its analysis of whether the original COOL measure constitutes
a technical regulation, the original panel had found that the measure laid down one or more
product characteristics through a country of origin labelling requirement.
1366 As noted 1367,
the technical changes introduced by the 2013 Final Rule do not affect the applicability of this
finding to the amended COOL measure. In fact, both the original and amended COOL measures
require labelling of meat at retail, i.e. at the point of sale to consumers. By imposing a country of
origin labelling requirement at retail, the amended COOL measure affects sales in the above broad
sense as it "has an effect on"
1368 "specific transactions, activities and uses relating to products in
the marketplace ('internal sale, offering for sale, purchase, transportation, distribution or use')"
within the meaning of Article III:4.
1369
7.640. Accordingly, we conclude that the amended COOL measure satisfies the second element of
the Article III:4 test.
7.7.5 Less favourable treatment1370
7.641. According to the Appellate Body, Article 2.1 of the TBT Agreement and Article III:4 of the
GATT 1994 are both concerned with whether the measure at issue "modifies the conditions of
competition in the market of the regulating Memb er to the detriment of the group of imported
products vis-à-vis the group of like domestic products." 1371 As explained, the Appellate Body
established that under Article III:4 of the GATT 1994, "an analysis of whether the detrimental
impact on competitive opportunities for like imported products is attributable to the specific
measure at issue does not involve an assessment of whether such detrimental impact stems
exclusively from a legitimate regulatory distinction".
1372
7.642. We found that the amended COOL measure has a detrimental impact on the competitive
opportunities of imported livestock in comparison with like US products. 1373 As the Appellate Body
has made clear, "[i]f the outcome of [the assessment of the implications of the contested measure
for the equality of competitive conditions between imported and like domestic products] is that the
measure has a detrimental impact on the conditions of competition for like imported products,
then such detrimental impact will amount to trea tment that is 'less favourable' within the meaning
of Article III:4."
1374 Hence, we conclude that the amended COOL measure accords less favourable
treatment within the meaning of Article III:4 of the GATT 1994.

do not bring claims either in regard to muscle cuts from foreign-slaughtered animals (Category D) or the
ground meat aspect of the amended COOL measure (Category E). See sections 7.1 and 7.4 above. See also

7.7.6 Conclusion on Article III:4 of the GATT 1994
7.643. In the light of these conclusions, we find that the complainants have made a prima facie
case, not rebutted by the United States, that the amended COOL measure fulfils all three elements
of the legal test under Article III:4 of the GATT 19 94. Accordingly, we find that that the amended
COOL measure violates Article III:4 of the GATT 1994 in respect of muscle cuts from US-
slaughtered livestock (Categories A-C).
7.8 Article XXIII:1(b) of the GATT 1994
7.644. In addition to their claims of violation, the complainants raise a non-violation claim under
Article XXIII:1(b) of the GATT 1994, which provides:
If any contracting party should consider that any benefit accruing to it directly or
indirectly under this Agreement is being nullified or impaired or that the attainment of
any objective of the Agreement is being impeded as the result of
…
(b) the application by another contracting party of any measure, whether or not it
conflicts with the provisions of this Agreement, …
…
the contracting party may, with a view to the satisfactory adjustment of the matter,
make written representations or proposals to the other contracting party or parties
which it considers to be concerned. Any contracting party thus approached shall give
sympathetic consideration to the representations or proposals made to it.
7.645. Article 26.1 of the DSU establishes the applicable rules for "Non-Violation Complaints of
the Type Described in Paragraph 1(b) of Articl e XXIII of GATT 1994", and provides in relevant
part:
Where the provisions of paragraph 1(b) of Article XXIII of GATT 1994 are applicable to
a covered agreement, a panel or the Appellate Body may only make rulings and
recommendations where a party to the dispute considers that any benefit accruing to
it directly or indirectly under the releva nt covered agreement is being nullified or
impaired or the attainment of any objective of that Agreement is being impeded as a
result of the application by a Member of any measure, whether or not it conflicts with
the provisions of that Agreement. Where and to the extent that such party considers
and a panel or the Appellate Body determines that a case concerns a measure that
does not conflict with the provisions of a covered agreement to which the provisions of
paragraph 1(b) of Article XXIII of GATT 1994 are applicable, the procedures in this
Understanding shall apply, subject to the following:
(a) the complaining party shall present a detailed justification in support of any
complaint relating to a measure which does not conflict with the relevant covered
agreement;
(b) where a measure has been found to nullify or impair benefits under, or impede the
attainment of objectives, of the relevant covered agreement without violation thereof,
there is no obligation to withdraw the measure. However, in such cases, the panel or
the Appellate Body shall recommend that the Member concerned make a mutually
satisfactory adjustment … .
7.646. We are mindful that "the remedy in Article XXIII:1(b) 'should be approached with caution
and should remain an exceptional remedy'."
1375 As noted by the Appellate Body, "Members

WT/DS384/RW • WT/DS386/RW

negotiate the rules that they agree to follow and only exceptionally would expect to be challenged
for actions not in contravention of those rules."1376
7.8.1 Jurisdiction of Article 21.5 compliance panels concerning non-violation claims
7.647. As a preliminary matter, the United States contends that non-violation claims are outside
the terms of reference of panels established under Article 21.5 of the DSU. According to the
United States, the text of Article 21.5 only permits compliance panels to consider either the
existence of a measure taken to comply with a previous adverse finding, or the consistency with a
covered agreement of a measure taken to comply.
1377 The United States argues that the latter
involves a determination of whether a measure taken to comply is inconsistent with a covered
agreement. In the United States' view, such ex amination of a measure's "consistency" does not
entail the question of non-violation nullification or impairment, which by definition concerns a
measure that does not conflict with the provisions of a covered agreement.1378
7.648. Canada and Mexico counter that a measure which does not conflict with the covered
agreements may still be inconsistent with them, meaning that non-violation claims under
Article XXIII:1(b) of the GATT 1994 are with in the scope of Article 21.5 of the DSU. 1379
According to the complainants, inconsistency with a covered agreement within the meaning of
Article 21.5 is broader than "conflict" with, or "violation" of, a covered agreement.
1380
7.649. In essence, the parties dispute the scope of Article 21.5 vis-à-vis Article 26 of the DSU and
Article XXIII:1(b) of the GATT 1994. This requires determining whether an "inconsistent" measure
necessarily "conflicts" with a provision of the covered agreements, or whether the notion of
"inconsistency" is broad enough to encompass measures that do not "conflict" with the covered
agreements, but that nevertheless nullify or impair a benefit accruing to a WTO Member.
7.650. The scope of inquiry of compliance panels is determined by Article 21.5 of the DSU.
In relevant part, Article 21.5 provides:
Where there is a disagreement as to the existence or consistency with a covered
agreement of measures taken to comply with recommendations and rulings such
dispute shall be decided through recourse to these dispute settlement procedures,
including wherever possible resort to the original panel.
7.651. The Appellate Body has clarified "the appropriate subject-matter of Article 21.5
proceedings" by explaining that, "[a]s in original dispute settlement proceedings, the 'matter' in
Article 21.5 proceedings consists of two elements: the specific measures at issue and the legal
basis of the complaint (that is, the claims)."
1381 In their requests for the establishment of a
compliance panel, the complainants identify the specific measure at issue, namely the amended

1380 Canada's second written submission, para. 154; Mexico's second written submission, para. 151.
The parties' submissions include reference to both "conflict" and "violation" in this context. As noted by
the Appellate Body, cases under Article XXIII:1(b) of the GATT 1994 are sometimes described as "non-
violation" cases, though the word "non-violation" does not appear in that provision. Appellate Body Reports, EC
– Asbestos, para. 185. We observe that the heading of Article 26.1 of the DSU is "Non-Violation Complaints of
the Type Described in Paragraph 1(b) of Article XXIII of GATT 1994". (emphasis added) In addition,
Article 26.1 references the situation where "a case concerns a measure that does not conflict with the
provisions of a covered agreement to which the provisions of paragraph 1(b) of Article XXIII of GATT 1994 are
applicable." (emphasis added)
In their arguments, the parties appear to concur in treating "conflict" and "violation" as equivalent in
the relevant provisions of the GATT 1994 and DSU. See Canada's second written submission, para. 155
(stating that "the first sentence of DSU Article 26.1 confirms the jurisdiction of 'a panel' in general to make
such a finding [of non-violation]"); Mexico's second written submission, paras. 145-152; and United States'

COOL measure, and include claims under Article XXIII:1(b) of the GATT 1994. In turn, our terms
of reference require us "[t]o examine, in the light of the relevant provisions of the covered
agreements cited by the parties to the disp ute, the matter referred to the DSB" in the
complainants' requests for the establishment of a compliance panel.
1382 Accordingly, the "subject-
matter" of these compliance proceedings does not a priori preclude the complainants' claims under
Article XXIII:1(b) of the GATT 1994.1383
7.652. We turn to the jurisdictional issue raised by the United States, beginning with the ordinary
meaning of the disputed treaty terms, namely "consistency" 1384 and "conflict(s)". 1385 A dictionary
definition of "consistency" is "being consistent; agreement ( with something, of things etc.);
uniformity, regularity" – with "consistent" defined as "congruous, compatible" 1386 – whereas
"conflict" is defined as "be[ing] incompatible". 1387 In turn, "compatible" is defined as "able to be
admitted or employed together or to coexist in the same subject; consistent, congruous". 1388
These dictionary definitions appear to overlap in terms of some notion of "compatibility", but they
do not clearly settle whether "consistency" in Article 21.5 may be broader than – or instead must
be exactly coterminous with – that which does not "conflict". In any event, we refrain from simply
equating the ordinary meaning of these terms "with the meaning of words as defined in
dictionaries", as this has been viewed by the Appellate Body as "too mechanical an approach".
1389
As the Appellate Body has stated, "dictionaries are important guides to, not dispositive statements
of, definitions of words appearing in agreements and legal documents." 1390 We therefore proceed
to examine the relevant context of the disputed terms.
7.653. The terms "consistent" and "conflict" (or variations thereof) appear in various places
throughout the covered agreements. Most relevantly, the term "consistent" appears in some form
in Articles 3.7, 19.1, and 21.5 of the DSU, and "conflict(s)" appears in Article 26 of the DSU and
Article XXIII:1(b) of the GATT 1994. Neither agre ement defines these terms or explains their
relationship. The French and Spanish versions of the DSU and GATT 1994 similarly use different
terms in Articles 3.7, 19.1, an d 21.5, on the one hand, and Arti cles 26 of the DSU and XXIII:1(b)
of the GATT 1994 on the other.1391
7.654. Article 19.1 of the DSU provides:
Where a panel or the Appellate Body concludes that a measure is inconsistent with a
covered agreement, it shall recommend that the Member concerned 9 bring the
measure into conformity with that Agreement.10
Appellate Body recommendations are directed.

1382 See Constitution of the Panel, Note by the Secretariat, WT/DS384/27 and WT/DS386/26, para. 2.
1383 See Articles 7.1 and 7.2 of the DSU. The Appellate Body considered that the phrase "these dispute
settlement procedures" in Article 21.5 "does encompass Article 6.2 of the DSU, and that Article 6.2 is generally
applicable to panel requests under Article 21.5." Appellate Body Report, US – FSC (Article 21.5 – EC II), para.
59. Although the Appellate Body did not consider it necessary "to determine the precise scope of th[e] phrase
['these dispute settlement procedures' in Article 21.5 of the DSU]", we follow the Appellate Body's guidance in
referring to the complainants' panel requests, made pursuant to Articles 6 and 21.5 of the DSU, to determine
the subject-matter of this dispute.

10 With respect to recommendations in cases not involving a violation of GATT 1994 or
any other covered agreement, see Article 26.
7.655. In turn, Article 26.1(b) of the DSU provides that where a non-violation claim is upheld,
"there is no obligation to withdraw the measure", but that instead "the panel or the Appellate Body
shall recommend that the Member concerned make a mutually satisfactory adjustment".
7.656. Two distinct remedial approaches are thereby established: one for measures found to be
"inconsistent" with one of the covered agreem ents (the panel or the Appellate Body shall
recommend that the measure be brought into conformity – Article 19.1), and another for
measures found to nullify or impair benefits without violation of a covered agreement (the panel or
the Appellate Body shall recommend that the Memb er make a mutually satisfactory adjustment –
Article 26.1).
1392 Reading these two provisions together, it could be argued that a finding that a
measure is "inconsistent" within the meaning of Article 19.1 does not encompass a finding of
nullification or impairment of benefits without violation of a covered agreement.
7.657. Nevertheless, we are mindful that the Appe llate Body has warned against an interpretive
approach that would "eviscerate the distinctive meaning that must be respected in the words of
the text". 1393 In our view, "consistency" in Article 21.5 and non-violation under Article 26.1
(i.e. "a measure that does not conflict") should not be given identical meaning so as to exclude
claims of the latter from reviews of compliance with the former.
7.658. The Appellate Body has clarified that "Article XXIII:1(b) of the GATT 1994 sets forth a
separate cause of action for a claim that, through the application of a measure, a Member has
'nullified or impaired' 'benefits' accruing to another Member, 'whether or not that measure conflicts
with the provisions' of the GATT 1994. Thus, it is not necessary, under Article XXIII:1(b),
to establish that the measure involved is inconsistent with, or violates, a provision of the
GATT 1994."
1394 Although the Appellate Body used the word "inconsistent" in its clarification of
non-violation claims, it was not addressing the term "consistency" in the specific context of
Article 21.5 of the DSU. Nor was it presented with the question of the jurisdiction of compliance
panels. Indeed, the Appellate Body stressed the na rrowness of the specific question raised on
appeal in that dispute, which related to the scope of application of Article XXIII:1(b). 1395
We therefore decline to read the Appellate Body's analysis as dispositive of the jurisdictional issue
before us in the present dispute.
7.659. Article 26 of the DSU provides that for "case[s] concern[ing] a measure that does not
conflict with the provisions of a covered agreem ent" under Article XXIII:1(b) of the GATT 1994,
"the procedures in this Understanding shall apply, subject to the following". It then proceeds to list
certain modifications to the DSU rules, none of which concern Article 21.5.
1396 Additionally,
Article 26 of the DSU refers generally to "a panel" making rulings and recommendations on non-
violation complaints. We find no reason, and the parties have not provided any, to conclude that a
compliance panel established pursuant to Article 21.5 would be excluded from the meaning of
"panel" in this context.
1397
7.660. To the extent that "conflict(s)" and "violation" can be considered equivalents 1398, we draw
further support from Article 23.1 of the DSU, which provides that "[w]hen Members seek the
redress of a violation of obligations or other nullification or impairment of benefits under the
covered agreements … they shall have recourse to, and abide by, the rules and procedures of this

1392 The dichotomy is strengthened by Article 3.7 of the DSU, which foresees withdrawal as the result of
a finding that a measure is "inconsistent with the provisions of any of the covered agreements".
1393 Appellate Body Report, Japan – Alcoholic Beverages II, p.26.
1394 Appellate Body Report, EC – Asbestos, para. 185. The Appellate Body also stated that "a measure
may, at one and the same time, be inconsistent with, or in breach of, a provision of the GATT 1994 and,
nonetheless, give rise to a cause of action under Article XXIII:1(b)". Ibid. para. 187
1395 Appellate Body Report, EC – Asbestos, paras. 184 and 190.
1396 Indeed, Article 26.1(c) provides that "notwithstanding the provisions of Article 21", the arbitration
provided for in Article 21.3 may include additional determinations and suggestions. This may suggest that the
other provisions of Article 21 of the DSU, including Article 21.5, "shall apply" to the cases referred to in
Article 26.1 of the DSU.
1397 See Canada's second written submission, para. 155.
1398 See footnote 1380 above.
WT/DS384/RW • WT/DS386/RW

Understanding."1399 Thus, as part of strengthening the multilateral system, WTO Members have
envisaged that non-violation nullification or impairment is to be redressed through the DSU,
without exclusion of any provisions therein.
7.661. The objective of Article 21.5 of the DSU is "to promote the prompt compliance with DSB
recommendations and rulings … by making it unnecessary for a complainant to begin new
proceedings and by making efficient use of the original panelists".
1400 It is clear that excluding
non-violation claims from Article 21.5 proceedings would not promote prompt compliance with
DSB recommendations and rulings and would not be efficient. Such exclusion could plausibly result
in the original complainant having to request the establishment of an entirely new panel to
adjudicate the non-violation complaint following the original respondent's measures to comply with
a recommendation or ruling. Indeed, the Appellate Body has clarified a compliance panel's
"mandate to assess whether a 'measure taken to comply' is fully consistent with WTO obligations"
– in recognition of the possibility that "a 'measure taken to comply' may be inconsistent with WTO
obligations in ways different from the original measure."
1401 If non-violation claims were
inadmissible under Article 21.5, a Member could avoid review under that Article by taking
measures that do not violate the covered agreements, but that nevertheless nullify or impair
benefits accruing to another Member.
7.662. In such a situation, a complainant would have to pursue both a compliance panel and an
entirely new panel to adjudicate the violation and non-violation aspects of the same measure
taken to comply. This seems incongruous with the objective of prompt dispute settlement
enshrined in Article 3.3 of the DSU, which specifically refers to "situations in which a Member
considers that any benefits accruing to it directly or indirectly under the covered agreements are
being impaired by measures taken by another Member". It would also be at odds with the principle
of "[p]rompt compliance with recommendations or ru lings of the DSB" found in Article 21.1 of the
DSU, and reflected in the design of Article 21. 5 of the DSU, which prescribes an expeditious
procedure including, wherever possible, resort to the original panel.
1402 In our view, such systemic
considerations weigh strongly against excluding non-violation claims from the jurisdiction of
compliance panels established under Article 21.5 of the DSU. Additionally, it seems to us that such
a reading would lead to increased litigation costs for all Members involved in disputes and
increased costs for the WTO.
7.663. Based on the above, we conclude that reviewing the "consistency" of a measure taken to
comply under Article 21.5 of the DSU extends to non-violation claims under Article XXIII:1(b) of
the GATT 1994 and Article 26.1 of the DSU. Accordin gly, we find that the complainants' claims
under Article XXIII:1(b) of the GATT 1994 are properly before us and fall within the competence of
this Article 21.5 compliance Panel.
7.8.2 Judicial economy
7.664. Having found that we have jurisdiction to entertain the complainants' non-violation claims,
we now turn to consider whether to exercise judicial economy on the substance of those claims. In
doing so, we take into account that we have already found that the amended COOL measure
violates Article III:4 of the GATT 1994 and Arti cle 2.1 of the TBT Agreement. The text of
Article XXIII:1(b) of the GATT 1994 clearly stipulates that a claim under that provision may arise
whether or not the contested measure conflicts with the GATT 1994. It is therefore possible for a
measure to simultaneously violate a provision of the GATT 1994 or another covered agreement,
and still give rise to a cause of action under Article XXIII:1(b).
1403
7.665. In assessing the propriety of judicial economy in this particular dispute, we recall that the
aim of the WTO dispute settlement system is "to resolve the matter at issue and 'to secure a

positive solution to a dispute'". 1404 In general, a panel may refrain from ruling on a claim "as long
as it does not lead to a 'partial resolution of the matter'". 1405 The original panel addressed judicial
economy on the complainants' non-violation claims based on the criterion of whether "compliance
… with the finding on Article III:4 [of the GATT 1994] would necessarily remove the basis of the …
claim of nullification or impairment ".
1406 The original panel exercised judicial economy, reasoning
that compliance with the findings of de facto discrimination under Article 2.1 of the TBT Agreement
would have removed the basis of the complainants' claims of non-violation nullification or
impairment.1407
7.666. The findings of violation in this compliance dispute differ from those of the original panel in
two significant respects. First, our finding of violation under Article 2.1 of the TBT Agreement
reflects the fact that Article 2.1 of the TBT Agreement does not prohibit all detrimental
modifications of the conditions of competition, bu t only those that do not stem exclusively from a
"legitimate regulatory distinction". 1408 Hence, a measure that modifies the conditions of
competition pursuant to a legitimate regulatory distinction may be consistent with Article 2.1 of
the TBT Agreement, while still causing nullification or impairment of a benefit under
Article XXIII:1(b) of the GATT 1994. In such a case , compliance with findings of violation under
Article 2.1 of the TBT Agreement would not necessarily remove the basis for nullification or
impairment.
7.667. Second, we have found that the amended COOL measure accords less favourable
treatment to imported livestock than to like US livestock under Article III:4 of the GATT 1994. 1409
In reaching this finding, we noted the Appellate Body's emphasis that this provision is concerned
with the "effective equality of opportunities for imported products to compete with like domestic
products".1410 According to the Appellate Body, this does not require an additional inquiry into
"whether the detrimental impact of a measure on competitive opportunities for like imported
products stems exclusively from a legitimate regulatory distinction".1411
7.668. Articles III:4 and XXIII:1(b) of the GATT 1994 are distinguishable in respect of their
standards of discrimination. Whereas Article III:4 concerns the "effective equality" of relative
conditions of competition for like products of foreign and domestic origin, Article XXIII:1(b) calls
for a temporal inquiry that compares "the competitive relationship between foreign and domestic
products at two specific points in time, i.e. when the concession was granted and currently".1412
7.669. Thus, whether or not the exercise of judicial economy is appropriate in this dispute may be
assessed by comparing (i) the competitive relationship between foreign and domestic products at
the time concessions were granted, and (ii) the "effective equality" of competitive conditions for
like foreign and domestic products. Unless the former is more favourable than the latter for the
competitive opportunities of imported products, compliance with a finding of violation under
Article III:4 (and consequent removal of detrimental impact) would necessarily remove the basis
of the non-violation claim.
7.670. In this case, compliance by the United States with our finding of violation of Article III:4
would require eliminating the detrimental impact on competitive opportunities for Canadian and
Mexican livestock altogether. Hence, restoring "effective equality" between foreign and domestic
products in this regard would necessarily remove the basis of nullification or impairment claimed
under Article XXIII:1(b). In fact, the complainants do not contend that the competitive relationship

(emphasis by original panel).
1408 Appellate Body Report, US – Clove Cigarettes, paras. 182 and 215.
1409 The original panel exercised judicial economy with respect to the complainants' claims under
Article III:4 of the GATT 1994 "[g]iven the close connection between Article 2.1 of the TBT Agreement and
Article III:4 of the GATT 1994 with respect to the nature of the obligations". Panel Reports, US – COOL,

WT/DS384/RW • WT/DS386/RW

existing at the time relevant concessions were granted – the focus of Article XXIII:1(b) – would be
more favourable than the standard of "effective equality" required under Article III:4.
7.671. Accordingly, we exercise judicial economy with respect to the complainants' non-violation
claims.
7.672. At the same time, we are mindful of the Appellate Body's admonition that a panel may
need to make additional findings in the event supporting findings or determinations are overturned
on appeal. 1413 We also recognize that, while Mexico raises a conditional non-violation claim,
Canada invokes Article XXIII:1(b) as an additional claim that is not made in the alternative to its
other claims of violation.1414 Thus, we proceed to analyse the complainants' non-violation claims so
that, were the Appellate Body to disagree with our findings on violation or with our approach to
judicial economy, it will have the benefit of our factual findings under Article XXIII:1(b).
We emphasise that, given our exercise of judicial economy, our examination is conditional and
primarily factual. We draw no legal conclusions in the subsequent sections of our Article XXIII:1(b)
analysis, and we limit any interpretation of relevant terms and provisions to what is necessary to
make conditional factual findings.
7.8.3 Legal test
7.673. The parties follow
1415 the three-step test for non-violation claims developed by the panel in
Japan – Film:
The text of Article XXIII:1(b) establishes three elements that a complaining party
must demonstrate in order to make out a cognizable claim under Article XXIII:1(b):
(1) application of a measure by a WTO Me mber; (2) a benefit accruing under the
relevant agreement; and (3) nullification or impairment of the benefit as a result of
the application of the measure.
1416
7.674. As the parties agree1417, the complainants bear the burden of proof to make a prima facie
case for their non-violation claims. 1418 Further, Article 26.1(a) of the DSU stipulates that
"the complaining part[ies] shall present a detailed justification in support of any complaint relating
to a measure which does not conflict with the relevant covered agreement". This is in line with the
exceptional nature of the non-violation remedy, which we bear in mind in examining the
complainants' non-violation claims.
7.8.4 Application of a measure
7.675. Under the first limb of the test, the comp lainants must demonstrate the application of a
measure by the United States. Both Canada and Mexico identify the amended COOL measure as
the measure being applied by the United States that allegedly nullifies or impairs benefits accruing
to them under the GATT 1994.
1419 This has not been contested by the United States.

1413 See Appellate Body Report, US – Tuna II (Mexico), para. 405:
the Panel should have made additional findings under the GATT 1994 in the event that the
Appellate Body were to disagree with its view that the measure at issue is a "technical
regulation" within the meaning of the TBT Agreement. As a result, it would have been necessary
for the Panel to address Mexico's claims under the GATT 1994 given that the Panel found no
violation under Article 2.1 of the TBT Agreement. By failing to do so, the Panel engaged, in our
view, in an exercise of "false judicial economy" and acted inconsistently with its obligations under
Article 11 of the DSU.

7.8.5 Benefit accruing
7.676. Canada and Mexico claim that the benefit nullified or impaired consists of legitimate
market access expectations from the United States' tariff concessions under the GATT 1994. 1420
Two issues are contested by the parties under this limb of the test:
a. whether the benefits claimed are in fact "accruing" to the complainants within the
meaning of Article XXIII:1(b) of the GATT 1994; and
b. whether the complainants could reasonably have anticipated the amended COOL
measure.1421
7.677. According to the United States' Goods Schedule annexed to the Marrakesh Protocol to the
GATT 1994, the MFN bound rate tariff for item number 0103, live swine, is zero. 1422 The North
American Free Trade Agreement (NAFTA) rate for live swine is also zero. 1423 Thus, the MFN bound
rate under the Uruguay Round concessions and the NAFTA rate are identical. Based on this, we
consider that benefits for live swine are currently being enjoyed by the complainants under the
GATT 1994 in the sense that relevant trade is conducted under its concessions. Accordingly,
the parties' disagreement the meaning of "benefit accruing" does not arise in respect of swine.
7.678. With regard to the bound rates for live cattle, the parties agree that under the relevant
US tariff bindings from the Uruguay Round, the cu rrent MFN rate for live cattle is USD 0.01 per
kilogram.
1424 They also agree that NAFTA accords duty-f ree access to the US market for Canadian
and Mexican live cattle.1425 Access to the US market for live cattle is, thus, more preferential under
NAFTA than it is under the relevant concessions from the Uruguay Round. In light of this, the
parties disagree on the meaning of "benefit accr uing" under Article XXIII:1(b) of the GATT 1994.
Specifically, the parties dispute whether a non-violation claim can be made in respect of benefits
stemming from the Uruguay Round when the releva nt trade is conducted under tariff concessions
arising from a preferential regional trade agreement.
7.679. Accordingly, the first issue concerns the definition of the term "benefit accruing" and arises
only for cattle. The second issue concerns the factual existence of a "benefit accruing" and whether
the complainants could reasonably have antici pated the amended COOL measure for both cattle
and swine.
7.8.5.1 Definition of "benefit accruing"
7.680. In addressing the term "benefit accruing ", we are confined by our terms of reference,
which require us "[t]o examine, in the light of the relevant provisions of the covered agreements
cited by the parties to the dispute, the matter referred to the DSB by [the complainants]".
1426
7.681. Article XXIII:1(b) of the GATT 1994 refers to "any benefit accruing to [a Member] directly
or indirectly under [the GATT 1994]." Similarly, Article 26.1 of the DSU refers to "any benefit

impairment claims is Article XXIII:1(b) of the GATT 1994. See also Article 3.2 DSU, which states that "[t]he
Members recognize that [the dispute settlement system of the WTO] serves to preserve the rights and
obligations of Members under the covered agreements, and to clarify the existing provisions of those
agreements in accordance with customary rules of interpretation of public international law" (emphasis added)
and Appellate Body Report, Mexico – Taxes on Soft Drinks, para. 56.

accruing to [a Member] directly or indire ctly under the relevant covered agreement".
Dictionary definitions of "benefit" include "an advantage, a good" and "pecuniary profit". 1427
Additionally, dictionary definitions of "accrue" include "of a benefit or sum of money[, to] be
received in regular or increasing amounts" and "arise or spring as a natural growth or result". 1428
In principle, these definitions do not preclude that a benefit may "accrue" without being actually
utilized.
7.682. By protecting benefits that accrue "directly or indirectly", both Article XXIII:1(b) of the
GATT 1994 and Article 26.1 of the DSU suggest a possibly broad scope for the term "benefit".
Further, both Articles refer to "any" benefit. Given the dictionary definition of the word "any",
these provisions might apply "no matter which, or what"
1429 particular benefit is at issue. This
would not support narrowing the term "benefit" to a specific manner of enjoyment or entitlement.
7.683. In any event, neither the dictionary defini tions of "benefit" and "accrue", nor the text of
Article XXIII:1(b) of the GATT 1994 and Article 26.1 of the DSU, provides a clear and dispositive
answer to the parties' disagreement about the me aning of "benefit accruing" as used in those
provisions.1430
7.684. Under Article II of the GATT 1994, Members' goods schedules "annexed to [the
GATT 1994] are … an integral part of … this Agreement." 1431 B y v i r t u e o f A r t i c l e I I o f t h e
GATT 1994, WTO tariff concessions serve as a form of insurance policy for Members. 1432
WTO Members have committed to an effective, g ood faith application of the WTO Agreement,
including their goods schedules.1433
7.685. In fact, one of the principal objectives of the WTO Agreement is to "promot[e] security and
predictability in international trade … through the exchange of concessions". 1434 The DSU also
serves this objective by subjecting the "cov ered agreements", including Members' goods
schedules, to WTO dispute settlement. 1435 The enforceability – and hence the predictability –
of multilateral concessions must not be compromised by concluding regional trade agreements.
To do otherwise would upset the predictability of the multilateral trading system, and would render
WTO concessions illusory, or – as termed by the respondent – "theoretical".1436

7.686. We note that Article XXVIII of the GA TT 1994 prescribes specific and formalised
procedures allowing Members to modify the concessions in their Schedules. 1437 These procedures
require negotiation and agreement with Members primarily concerned, as well as consultations
with other Members having substantial interest, and they cannot be circumvented.
1438 Moreover,
modification does not come without a price: Members concerned "shall endeavour to maintain a
general level of reciprocal and mutually advantageous concessions not less favourable to trade
than that provided for in [the GATT 1994] prior to such negotiations", and "may include provision
for compensatory adjustment with respect to other products".
1439
7.687. In regulating entry into preferential regional and bilateral trade agreements, Article XXIV
of the GATT 1994 allows for the establishment of customs unions and free trade areas, stipulating
that "[t]he purpose of a customs union or a free-trade area should be to facilitate trade … and not
to raise barriers to … trade." 1440 Thus, the formation of regional trade agreements is not meant to
undermine WTO concessions and other obligations, or to frustrate WTO market access benefits.
Indeed, Article XXIV:6 provides that if a Member entering into a customs union or free trade
agreement "proposes to increase any rate of duty inconsistently with the provisions of Article II,
the procedure set forth in Article XXVIII shall apply". This reflects the principle that each WTO
Member entering into a free trade agreement re mains bound by its WTO commitments, including
bound tariff ceilings.
7.688. In sum, it would be an impermissibl y narrow reading of "benefit accruing" in
Article XXIII:1(b) of the GATT 1994 and Article 26.1 of the DSU to limit that term to concessions
that are actually enjoyed or applied to trade in the relevant goods. WTO Members have assigned
primary importance to "[t]he prompt settlement of situations in which a Member considers that
any benefits accruing to it directly or indirectly under the covered agreements are being impaired
by measures taken by another Member".
1441 Accordingly, we are guided by the role of WTO
dispute settlement as a "central element in providin g security and predictability to the multilateral
system … [and] preserv[ing] the rights and obligations of Members under the covered
agreements".
1442
7.689. In the context of this dispute, the approa ch argued by the United States, requiring goods
to be subject to and currently utilizing a particular concession, would potentially bar Members from
relying on WTO concessions for claims of non-violation when their trade was being conducted
under a preferential trade agreement. We note that Article XXIII:1(b) of the GATT 1994 has been
construed as protecting "commitments on conditions of competition for trade".
1443 In other words,
"competitive opportunities"1444, not just their actual, or current, enjoyment are protected under
Article XXIII:1(b) of the GATT 19 94 and Article 26.1 of the DSU. 1445 Based on the above
considerations, the phrase "benefit accruing" in Article XXIII:1(b) of the GATT 1994 and

1437 See Article XXVIII of the GATT and the Understanding on the Interpretation of Article XXVIII of the

Article 26.1 of the DSU extends to multilateral WTO market access concessions even when the
relevant products are directly traded under a regional trade agreement according preferential
market access.
7.690. We decline to read Article XXIII:1(b) of the GATT 1994 and Articl e 26.1 of the DSU in a
manner that would render inutile multilateral concessions and key obligations in the covered
agreements and frustrate their enforceability. In lig ht of the above, we conditionally conclude that
the United States' relevant Uruguay Round multilateral concessions for cattle can be covered by
the term "benefit accruing" in the sense of Article XXIII:1(b) and Article 26.1 of the DSU.
1446
7.8.5.2 Reasonable anticipation of the measure
7.691. As noted above, the second issue contested under the second limb of the Article XXIII:1(b)
test is whether the benefit allegedly accruing to the complainants from Uruguay Round
concessions creates legitimate expectations of market access. That is contingent on the contested
measure not having been reasonably anticipated
1447 at the time the concessions were made.1448
7.8.5.2.1 Timeline of the COOL measure
7.692. A chronology of the amended COOL measure is essential for addressing the question of its
reasonable anticipation by the complainants. The statutory framework of the amended COOL
measure, the COOL statute, consists of the Agricu ltural Marketing Act of 1946 as amended by the
2002 Farm Bill and the 2008 Farm Bill.
1449 While the initial legislative act dates to 1946,
the relevant country of origin labelling requirements for the products at issue originate in the
2002 Farm Bill, and were subsequently modified in the 2008 Farm Bill.
1450
7.693. The original panel found that "[a]lthough the COOL measure was introduced in its initial
form by the 2002 Farm Bill, it took effect as a fully developed and enforceable legal requirement
for the products at issue in [the original] dispute on 30 September 2008." 1451 Based on this
statutory framework, the 2009 and 2013 Final Rule s were the implementing regulations providing
"the details necessary for the program to operate in the market". 1452 Thus, the legislation of the
contested COOL requirements emerged in 2002 an d took definitive shape in 2008, followed by
more specific regulations in 2009 and 2013.1453
7.694. This chronology indicates that the relevant measure came into force years after the
negotiation of the Uruguay concessions that are claimed to create the complainants' legitimate
expectations of market access.
1454 Before reaching any conditional conclusion from this for

1446 As explained above, this legal question does not arise with respect to swine. See paras. 7.677-7.679
above.

written submission, para. 208.
1449 See section 7.3 above.
1450 According to the USDA's background summary of the 2009 Final Rule, "[t]he Farm Security and
Rural Investment Act of 2002 (2002 Farm Bill), the 2002 Supplemental Appropriations Act (2002
Appropriations), and the Food, Conservation and Energy Act of 2008 (2008 Farm Bill) amended the Agricultural
Marketing Act of 1946 (Act) to require retailers to notify their customers of the country of origin of covered
commodities." 2009 Final Rule, p.2658 (emphasis added). Further, the USDA stated that the 2009 Final Rule
was "the direct result of statutory obligations to implement the COOL provisions of the 2002 and
2008 Farm Bills." 2009 Final Rule, p.2693. See also 2013 Final Rule, p. 31367.
1452 United States' first written submission, para. 9.
1453 This development of the original and amended COOL measures is confirmed by the account of the
Congressional Research Service. "With the passage of the 2002 farm bill, retail-level COOL was to become
mandatory for … beef [and] pork … starting September 30, 2004". After postponement of implementation by
Appropriations Acts of 2004 and 2006, "[p]rovisions dealing with record-keeping requirements, the factors to
be considered for labeling U.S. and non-U.S. origin products, and penalties for noncompliance were modified
[by the 2008 Farm Bill]." Exhibit CDA-8, p. 1; see also pp. 1-2 and 27 regarding the USDA's issuance of the
2009 and 2013 Final Rules.
1454 For example, the panel in Japan – Film considered that "in the case of measures shown … to have
been introduced subsequent to the conclusion of the tariff negotiations at issue, it is our view that the
WT/DS384/RW • WT/DS386/RW

reasonable anticipation of the amended COOL me asure, we analyse other factors argued by the
United States.
7.8.5.2.2 Connection to earlier measures in the United States
7.695. A further question in the context of reasonable anticipation is whether a measure may be
"so clearly contemplated in an earlier measure that [the complainants] should be held to have
anticipated it".
1455 To demonstrate this, it would not be sufficient to show merely that the measure
"is consistent with or a continuation of a past general government policy", but rather that there is
a "clear connection" between the challenged and earlier measures.1456
7.696. The United States argues that "imported me at, along with a host of other agricultural and
non-agricultural goods, has been required to be labelled at the retail level with its country of origin
since 1930, decades before the conclusion of the Uruguay Round or the NAFTA."
1457 According to
the United States, its "own long history of labeling laws and policy discussion on meat and other
products, as well as the proliferation of similar labeling regimes by other WTO Members, prior to
the time the Uruguay Round was concluded" show that the complainants could have reasonably
anticipated the amended COOL measure.
1458
7.697. Apart from the COOL statute1459, the United States refers to the Tariff Act of 19301460 as an
earlier measure that required "imported meat … to be labelled at the retail level with its country of
origin since 1930". 1461 The Tariff Act of 1930 has required, since its enactment, the labelling of
"every article of foreign origin".1462 Such articles of foreign origin would encompass imported meat,
along with many other agricultural and non-agricultural goods.1463
7.698. We observe, however, that there are notable differences in the nature and extent of the
obligations imposed by the Tariff Act of 1930 and the amended COOL measure. As explained by
the United States in reference to the Tariff Act of 1930, "these previous labeling requirements did
not apply to many of the products covered by the amended COOL measure, including meat derived
from animals slaughtered in the United States."
1464 Indeed, according to the 2009 Final Rule:
Under preexisting Federal laws and regulations, COOL is not universally required for
the commodities covered by this rule. In particular, labeling of United States origin is
not mandatory, and labeling of imported products at the consumer level is required
only in certain circumstances. Thus, the Agency has not identified any Federal rules
that would duplicate or overlap with this rule.
1465
7.699. The 2013 Final Rule makes a similar observation with regard to the requirement to give
point-of-production information for the animals from which covered muscle cuts are derived:
Under preexisting Federal laws and regulations, origin designations for muscle cut
covered commodities need not specify the production steps of birth, raising, and

[complainant] has raised a presumption that it should not be held to have anticipated these measures and it is
then for [the respondent] to rebut that presumption." Panel Report, Japan – Film, para. 10.79.

para. 8.291(a).
1457 United States' first written submission, para. 212.
1458 United States' first written submission, para. 215.
1459 As explained, the relevant requirements of the COOL statute came into effect no earlier than 2002
and assumed their current form in 2008, notwithstanding the 1946 enactment of the original Agricultural
Marketing Act.

slaughter of the animals from which the cu ts are derived. Thus, the Agency has not
identified any Federal rules that would duplicate or overlap with this rule.1466
7.700. In keeping with these statements, the co mplainants highlight the original and amended
COOL measures' departure from the principle of su bstantial transformation in previous labelling
requirements.1467 The application of the Tariff Act of 1930 to imported meat excluded "meat
derived from animals slaughtered in the United States".1468 These are the very products claimed by
the United States to be a primary aspect of the amended COOL measure's coverage 1469, as well as
the focus of the complainants' allegations of nullification or impairment. In effect, earlier
requirements cited by the United States would have extended no further than the equivalent of
Label D under the original and amended COOL measures. As found with respect to both the
original and amended COOL measures, this represen ts a small percentage of the meat sold in the
United States.
1470
7.701. Hence, although there was a past governme nt policy of labelling imported meat with its
country of origin, we do not consider this to demonstrate a reasonable anticipation of the key
features and requirements of the amended COOL measure. In particular, the mandatory retail
labelling of meat from US-slaughtered livestock, including the recent specifications under the
amended COOL measure, appears to be a signific ant departure from pre-existing labelling rules
and practices as they concern the products at issue.
1471
7.702. The United States also discusses the domestic history of US labelling laws and policy
discussions on meat. It submits that "for at least the last 40 years, since the 1960s, the U.S.
Congress has contemplated various pieces of legislation that would have imposed additional
requirements for country of origin labelling for meat at the retail level."
1472 Our reading of these
non-enacted proposals does not reveal any clear connection with the amended COOL measure,
as these proposals would have applied only to imported meat rather than livestock and would not
have required detailed information about where the animal was born and raised.
1473
Even assuming that the complainants would have been aware of the measures introduced in the
United States Congress, it is not clear that those proposed measures could have alerted them to
the possibility of a measure such as the amended COOL measure.
1474
7.703. In any case, it is questionable whether legislative initiatives that are not enacted into
mandatory legislation suffice to establish reasonable anticipation on the part of the
complainants.
1475 Even charging Canada and Mexico with knowledge of the legislative initiatives,
the indicative value of that knowledge could be inconclusive. The very fact that successive
proposals were defeated in Congress might plausibly have led the complainants to expect that any
similar (or more rigorous) future proposals would also be rejected.

original and amended COOL measure as being "fundamentally different from previous labeling measures
applied to beef in the U.S. market").

1472 United States' first written submission, para. 213.
1473 See United States' response to Panel question No. 78.
1474 The only proposal with some similarity to the amended COOL measure dates from 1999, which could
not possibly have forewarned the complainants at the close of the Uruguay Round years earlier to anticipate a
significant change in country of origin labelling requirements. See Country of Origin Meat Labeling Act of 1999,
H.R. 1144, 106
th Cong. (1st Sess. 1999) (introduced by Rep. Helen Chenoweth-Hage). This proposed legislation
would have amended the Federal Meat Inspection Act to require that all meat and meat food products, whether
domestic or imported, bear a label notifying the ultimate purchaser of meat and meat food products of the
country of origin of the livestock that is the source of the meat and meat food products. Exhibit CDA-9 in the
original dispute.
1475 For instance, the panel in Japan – Film considered that a complainant could be "charged with
knowledge of … measures as of the date of their publication." Panel Report, Japan – Film, para. 10.80.
WT/DS384/RW • WT/DS386/RW

7.8.5.2.3 International prevalence of similar measures
7.704. The United States additionally argues that "the proliferation of similar labeling regimes by
other WTO Members, prior to the time the Uruguay Round was concluded, 'could not do other than
create a climate which should have led [Canada and Mexico] to anticipate a change in the attitude
of the importing countries' towards embracing more origin information being disclosed to
consumers at the retail level."
1476 To support an inference of reasonable anticipation, the
United States submitted a list of WTO Members with country of origin regimes. 1477
The United States acknowledges that of the numerous measures of other Members referenced,
only a handful of measures (from Australia, Barbados, Canada, Chile, Chinese Taipei, Colombia,
the European Union, Korea, Japan, and Mexico) concern meat in particular.
1478
7.705. The adoption by other Members of measures with some similarity to the challenged
measure does not necessarily mean that the latter should reasonably have been anticipated. 1479
For instance, the panel in Japan – Film did not "consider that as a general rule the United States
should have reasonably anticipated Japanese measures that are similar to measures in other
Members' markets. In each such instance, the issue of reasonable anticipation needs to be
addressed on a case-by-case basis." 1480 Similarly, the panel in EC – Asbestos considered that "the
accumulation of international and Community decisions concerning the use of asbestos … did not
necessarily make it certain that the use of asbestos would be banned by France".1481
7.706. From the information provided by the Un ited States, it appears that only one other
measure mandates the provision of information on the country where the animal from which the
meat is harvested was born, raised, and slaughtered.
1482 This does not support a high degree of
international prevalence or similarity of the measures from other jurisdictions to the amended
COOL measure.1483 Moreover, there is wide variation in the proffered reasons for the adoption of

1476 United States' first written submission, para. 215 (citing Panel Report, EC – Asbestos, para. 8.297).

should have reasonably anticipated Japanese measures that are similar to measures in other Members'
markets. In each such instance, the issue of reasonable anticipation needs to be addressed on a case-by-case
basis." Panel Report, Japan – Film, para. 10.79. Likewise, in EC – Asbestos the panel considered that
"the accumulation of international and Community decisions concerning the use of asbestos … did not
necessarily make it certain that the use of asbestos would be banned by France". Panel Report, EC – Asbestos,
para. 8.297.
1482 United States' first written submission, para. 39 and footnote 87; Exhibits US-5 and US-6. We refer
here to the EU measure (See Notification to the TBT Committee, G/TBT/N/EU/158, of 7 October 2013) and the
United States' description of that measure in the United States' first written submission, para. 40.
1483 From the information available to us from the TBT Committee notifications of the other Members
specifically referred to by the United States, it appears that none requires the provision of information to
consumers on the country or countries where the animal was born, raised and slaughtered. Instead, what is
required is the identification of the country of origin of the product covered or, in the case of processed food, of
individual ingredients in the product. It is not possible to deduce from the information provided by the
United States how the county of origin is determined. Moreover, there is variation as to the scope of product
coverage of those measures. See Exhibit US-10. The Australian measure (G/TBT/N/AUS/45 of 13 December
2005; G/TBT/N/AUS/70 of 23 August 2011; G/TBT/N/AUS/70/Add.1 of 8 January 2013) covers both packaged
and unpackaged meat. The Barbadian measure (G/TBT/N/BRB/2 of 15 November 2005) covers pre-packaged
meat. The Canadian measure (Exhibit US-9, in particular Sections 109 and 123) covers meat products. The
Chilean measure (G/TBT/N/CHL/33 of 5 June 2002) applies to packaged food for human consumption. The first
measure of Chinese Taipei (G/TBT/N/TPKM/41 of 13 December 2006) requires the labelling of all pre-packaged
foods with the origin of the ingredient. The second measure of Chinese Taipei (G/TBT/N/TPKM/126 of 29
August 2012) requires the labelling of meat with the country of origin of the product or, in the case of beef and
edible cattle offals, with the country where the animal was slaughtered. The first Colombian measure
(G/TBT/N/COL/69 of 31 August 2005; G/TBT/N/COL/69Add.1 of 14 February 2006) applies to ingredients listed
on containers and packages used for all food for human consumption. The second Colombian measure
(G/TBT/N/COL/82 of 22 December 2006; G/TBT/N/COL/82/Add.1 of 7 June 2007) applies to meat, edible meat
products and meat by-products for human consumption and does not seem to impose labelling requirements.
The first Japanese measure (G/TBT/Notif.99/668 of 23 December 1999) applies inter alia to all processed foods
and certain fresh foods and appears to concern labelling standards in general. The second relevant Japanese
measure (G/TBT/Notif.00/483 of 9 October 2000; G/TBT/N/JPN/7 of 24 January 2001; G/TBT/N/JPN/12 of 12
WT/DS384/RW • WT/DS386/RW

those measures, including public health 1484, the proper identification of meat cuts and their
quality1485, the provision of information to consumers 1486, consumer protection 1487, and the
avoidance of deceptive practices.1488
7.707. Under such circumstances, the existence of labelling requirements in other countries does
not evidence the kind of "trend" that could give rise to a "climate" in which the amended COOL
measure could reasonably have been anticipated.1489
7.8.5.2.4 Measures pursuing legitimate policy objectives
7.708. Finally1490, we address the relevance for non-violation claims of the covered agreements'
recognition of specific objectives that may be pursued by Members. In this regard,
the United States points to the prevention of deceptive practices as a "legitimate objective" under
Article 2.2 of the TBT Agreement.
1491
7.709. We note that the panel in EC – Asbestos applied a "stricter burden of proof" for non-
violation claims against measures pursuing certain recognized interests. 1492 In particular, the EC –
Asbestos panel considered for Article XX of the GA TT 1994 that "in accepting the WTO Agreement
Members also accept, a priori, through the introduction of these general exceptions, that Members
will be able, at some point, to have recourse to these exceptions". 1493 The panel thus reasoned
that recourse to Article XXIII:1(b) of the GATT 19 94 should be treated as particularly exceptional
in relation to measures justified by Article XX of the GATT 1994.1494
7.710. The exceptional treatment suggested above would impute greater awareness to
complainants of the possibility that other Member s might regulate under the general exceptions of
the GATT 1994 in ways nullifying or impairing WTO concessions. At the same time, a measure's
justification based on its pursuit of a legitimate objective should not be grounds, in and of itself,
for finding that that measure could reasonably have been anticipated. 1495 Otherwise, the non-

April 2001; G/TBT/N/JPN/42 of 25 March 2002; G/TBT/N/JPN/124 of 18 June 2004) applies to fresh and
processed food. It was amended in 2004 to remove a country of origin labelling rule for livestock meat derived
from animals imported live and slaughtered in Japan. The first Korean measure applies to all meat products
being commercially sold (G/TBT/N/KOR/156 of 18 September 2007; G/TBT/N/KOR/202 of 20 January 2009);
the second one (G/TBT/N/KOR/173 of 7 May 2008) covers food, food additives, apparatus, packaging and
containers for food; and the third one (G/TBT/N/KOR/181 of 7 August 2008) applies inter alia to beef and pork.
The Mexican measure (Mexican Official Standard NOM-194-SSA1-2004 on Sanitary Specifications for
Establishments Dedicated to Slaughtering and Preparing Animals for Slaughter, Storage, Transport and
Vending, available at http://www.salud.gob.mx/unidades/cdi/nom/194ssa104.html, last accessed 3 June 2014)
applies to meat, ground meat, viscera and other edible parts. See also United States' first written submission,
paras. 40-44.
1484 See the Australian, Barbadian, Chinese Taipei, Colombian and Korean measures cited above in
footnote 1483 and in Exhibit US-5.
1485 See the Barbadian measure cited above in footnote 1483 and in Exhibit US-5.
1486 See the Australian, Barbadian, Chinese Taipei, Chilean, European Union and Korean measures cited
above in footnotes 1482 and 1483 and in Exhibit US-5.
1487 See the Chinese Taipei and Japanese measures cited above in footnote 1483 and in Exhibit US-5.
1488 See the Australian, Colombian and Korean measures cited above in footnote 1483 and in
Exhibit US-5.
1489 See Panel Report, EC – Asbestos, para. 8.297.
1490 Another possible factor to consider is the temporal gap between the coming into being of the
challenged measure and the granting of concessions of market access. The United States submits that "in light
of the many years that have elapsed since the Uruguay Round, Canada and Mexico 'could not assume that,
over such a long period, there would not be' changes to the U.S. labeling regime with the risk that meat
products derived from imported livestock would have to be labeled." United States' first written submission,
paras. 215 (citing Panel Report, EC – Asbestos, para. 8.292). The panel in EC – Asbestos emphasised the long
time that had lapsed between the concessions and the measure (between 35 and 50 years). However, the
force of that argument is significantly reduced in the context of this dispute where the relevant legislative acts
were adopted in 2002 and 2008, much closer in time to the granting of Uruguay Round concessions.

violation remedy for measures that do not conflict with – including those justified under – the
covered agreements would be rendered ineffective.1496
7.711. In the present compliance dispute, the above considerations do not alter our analysis of
the amended COOL measure's reasonable anticipation. 1497 The amended COOL measure's
legitimate objective 1498 and the prevention of deceptive practices as recognized in the
TBT Agreement could only evidence a general government policy of labelling foreign products with
some indication of their country of origin. As described above, however, "it is not sufficient to
claim that a specific measure should have been anticipated because it is consistent with or a
continuation of a past general government policy."
1499 To the extent that the amended COOL
measure marks a notable departure from such past policy, it would not be reasonably anticipated
simply by virtue of pursuing a recognized or legitimate objective.
7.8.5.2.5 Conclusion on reasonable anticipation
7.712. In sum, the chronology of the amende d COOL measure's introduction shows that it
postdates the granting of relevant tariff concessions. As for the other factors we have examined,
we do not find compelling evidence that the amended COOL measure could have been reasonably
anticipated before its adoption. Overall, and having assessed the relevant facts and
circumstances
1500, we conditionally conclude that the amended COOL measure introduced a
significant degree of regulatory novelty to the labelling of the products relevant in this dispute.
7.8.6 Nullification or impairment and causation
7.713. The third limb of the Article XXIII:1(b) test concerns the existence and causation of
nullification or impairment.
1501 The complainants argue that the amended COOL measure has
upset the competitive relationship between US and Canadian and Mexican cattle and hogs
established by the United States' tariff bindings. 1502 In particular, Canada contends that both the
original and the amended COOL measures discour age US slaughterhouses from buying Canadian
cattle and hogs, and retailers from selling Canadian beef and pork. 1503 According to Canada, this
worsens the competitive position of Cana dian cattle and hogs in the US market. 1504 Mexico argues
that segregation according to origin conti nues under the amended COOL measure, and US
producers continue to apply a price discount on Mexican-born cattle. 1505 Mexico notes that the
number of processors accepting Mexican cattle "remains restricted" 1506, and US processors
continue to require advance delivery notice for Mexican cattle. 1507 The United States does not
contest that the amended COOL measure is one of the factors that affect trade of livestock
between its market and those of Canada and Mexico.1508
7.714. With regard to the causal link between the amended COOL measure and the nullification or
impairment of relevant benefits, the complainants must establish "a clear correlation between the

1496 See also Appellate Body Report, EC – Asbestos, para. 187.
1497 As a threshold matter, the panel's justifications in EC – Asbestos for according stricter treatment to
non-violation claims are not clearly applicable to the present dispute. The panel in EC – Asbestos addressed
"the special situation of measures justified under Article XX, insofar as they concern non-commercial interests
whose importance has been recognized a priori by Members". Panel Report, EC – Asbestos, para. 8.281. The
Appellate Body expressed doubts as to the distinction of "non-commercial" interests, stating that "in practice,
clear distinctions between health and commercial measures may be very difficult to establish". Appellate Body
Report, EC – Asbestos, para. 189. As pointed out by Canada, the panel in EC – Asbestos was explicitly
concerned with Article XX of the GATT 1994, which has not been relied upon by the United States. See
Canada's comments on the United States' response to Panel question No. 78, para. 121.

measures and the adverse effect on the relevant competitive relationships". 1509 The criterion of
causality consists in showing that the amended COOL measure "has made more than a de minimis
contribution to nullification or impairment".1510
7.715. In light of the above and the parties' ar guments on the third limb of the complainants'
non-violation claim, we conditionally conclude that the amended COOL measure meets the
requirement of causing an adverse effect on the relevant competitive relationships.
7.8.7 Conclusion on Article XXIII:1(b) of the GATT 1994
7.716. We have explained that compliance by the United States with our finding of violation under
Article III:4 of the GATT 1994 would necessarily remove the basis of the complainants'
non-violation claims. Consequently, we decided to exercise judicial economy with respect to the
complainants' non-violation claims under Article XXIII:1(b) of the GATT 1994. To the extent that
the findings underpinning our exercise of judici al economy are overturned on appeal, we have
reviewed relevant factual and interpretive issues, and have reached conditional factual conclusions
on this basis.

8 CONCLUSIONS AND RECOMMENDATIONS
8.1. We recall that at the substantive meetin g of 18 and 19 February 2014, the parties did not
object to including the Panel Reports in a single document, with the understanding that, following
the same approach as in the original dispute, the final sections on Conclusions and
Recommendations would be printed on separate pages with the relevant DS symbol.
Accordingly, we provide two separate sets of findings and recommendations, with separate
numbers/symbols for each complainant (WT/DS384 for Canada and WT/DS386 for Mexico).
8.2. In making these findings, we recall our above observations in respect of potential WTO-
consistent solutions for achieving the amended COOL measure's legitimate objective.

8.1 Complaint by Canada (DS384): Conclusions and recommendations
8.3. With respect to Canada's claims under the TBT Agreement, we conclude that:
a. the amended COOL measure is a "technical regulation" within the meaning of Annex 1.1
to the TBT Agreement;
b. the amended COOL measure violates Article 2.1 because it accords imported Canadian
livestock treatment less favourable than that accorded to like domestic livestock,
in particular because the amended COOL measure increases the original COOL measure's
detrimental impact on the competitive opportunities of imported Canadian livestock, and
this detrimental impact does not stem exclusively from legitimate regulatory distinctions;
and
c. Canada has not made a prima facie case that the amended COOL measure is more trade
restrictive than necessary within the meaning of Article 2.2.
8.4. With respect to Canada's claims under the GATT 1994, we conclude that the amended COOL
measure violates Article III:4, as it has a detrimental impact on the competitive opportunities of
imported Canadian livestock, and thus accords less favourable treatment within the meaning of
Article III:4 of the GATT 1994. In light of the abov e findings of violation, in particular under
Article III:4 of the GATT 1994, we have exercised judicial economy with regard to Canada's non-
violation claim under Article XXIII:1(b) of the GATT 1994; at the same time, we have set out
conditional, factual conclusions and legal interpretations in the event that our supporting findings
or determinations are overturned on appeal.
8.5. Under Article 3.8 of the DSU, in cases wh ere there is an infringement of the obligations
assumed under a covered agreement, the action is considered prima facie to constitute a case of
nullification or impairment of benefits under that agreement. Accordingly, we conclude that, to the
extent that the United States has acted inconsis tently with Article 2.1 of the TBT Agreement and
Article III:4 of the GATT 1994, it has nullified or im paired benefits accruing to Canada under these
agreements.
8.6. Pursuant to Article 19.1 of the DSU, having found that the United States has acted
inconsistently with Article 2.1 of the TBT Agreement and Article III:4 of the GATT 1994,
we recommend that the Dispute Settlement Body request the United States to bring the
inconsistent measure into conformity with its obligations under the TBT Agreement and the
GATT 1994.

8.2 Complaint by Mexico (DS386): Conclusions and recommendations
8.3. With respect to Mexico's claims under the TBT Agreement, we conclude that:
a. the amended COOL measure is a "technical regulation" within the meaning of Annex 1.1
to the TBT Agreement;
b. the amended COOL measure violates Article 2.1 because it accords imported Mexican
livestock treatment less favourable than that accorded to like domestic livestock,
in particular because the amended COOL measure increases the original COOL measure's
detrimental impact on the competitive opportunities of imported Mexican livestock, and
this detrimental impact does not stem exclusively from legitimate regulatory distinctions;
and
c. Mexico has not made a prima facie case that the amended COOL measure is more trade
restrictive than necessary within the meaning of Article 2.2.
8.4. With respect to Mexico's claims under the GATT 1994, we conclude that the amended COOL
measure violates Article III:4, as it has a detrimental impact on the competitive opportunities of
imported Mexican livestock, and thus accords less favourable treatment within the meaning of
Article III:4 of the GATT 1994. In light of the abov e findings of violation, in particular under
Article III:4 of the GATT 1994, we have exercised ju dicial economy with regard to Mexico's non-
violation claim under Article XXIII:1(b) of the GATT 1994; at the same time, we have set out
conditional, factual conclusions and legal interpretations in the event that our supporting findings
or determinations are overturned on appeal.
8.5. Under Article 3.8 of the DSU, in cases wh ere there is an infringement of the obligations
assumed under a covered agreement, the action is considered prima facie to constitute a case of
nullification or impairment of benefits under that agreement. Accordingly, we conclude that, to the

Article III:4 of the GATT 1994, it has nullified or im paired benefits accruing to Mexico under these
agreements.
8.6. Pursuant to Article 19.1 of the DSU, having found that the United States has acted
inconsistently with Article 2.1 of the TBT Agreement and Article III:4 of the GATT 1994,
we recommend that the Dispute Settlement Body request the United States to bring the
inconsistent measure into conformity with its obligations under the TBT Agreement and the
GATT 1994.
