Having heard the Council of State (Social Affairs Section),
Decrees:
Article 1
I. For the purpose of protecting workers, and pursuant to Article L. 231-7 of the Labour Code,
the manufacture, processing, sale, import, placing on the domestic market and transfer under any title
whatsoever of all varieties of asbestos fibres shall be prohibited, regardless of whether these
substances have been incorporated into materials, products or devices.
II. For the purpose of protecting consumers, and pursuant to Article L. 221.3 of the Consumer
Code, the manufacture, import, domestic marketing, exportation, possession for sale, offer, sale and
transfer under any title whatsoever of all variet ies of asbestos fibres or any product containing
asbestos fibres shall be prohibited.
III. The bans instituted under Articles I and II shall not prevent fulfilment of the obligations
arising from legislation on the elimination of wastes.
Article 2
I. On an exceptional and temporary basis, the bans instituted under Article 1 shall not apply to
certain existing materials, products or devices containing chrysotile fibre when, to perform an
equivalent function, no substitute for that fibre is available which:
- On the one hand, in the present state of scientific knowledge, poses a lesser
occupational health risk than chrysotile fibre to workers handling those materials,products or devices;
- on the other, provides all technical guarantees of safety corresponding to the ultimate
purpose of the use thereof.
II. The scope of application of paragraph I of this Article shall cover only the materials, products
or devices falling within the categories shown in an exhaustive list decreed by the Ministers forLabour, Consumption, the Environment, Industry, Agriculture and Transport.  To ascertain the
justification for maintaining these exceptions, the list shall be re-examined on an annual basis, after
which the Senior Council for the Prevention of Occupational Hazards and the National Commission
for Occupational Health and Safety in Agriculture shall be consulted.
Article 3
I. The manufacture, processing, importation and domestic marketing of any of the materials,
products or devices falling into one of the categories mentioned on the list envisaged under Article 2
shall be subject to a statement, signed, as appropria te, by the head of the business establishment, the
importer or the party responsible for domestic marketing, which should be addressed to the Minister
for Labour.  This statement shall be filed in January of each year or, as appropriate, three months
before the start of a new activity or the alteration of an existing production activity, by means of a
form decreed by the Ministers for Labour, Consumption, Industry and Agriculture.
The statement shall be accompanied by all the supporting documents in the possession of the
declaring party making it possible, considering the state of scientific and technological progress, to
determine that as of the date of signature of the statement, the activity covered by the statement meets
the conditions set forth in Article 2.I.WT/DS135/R/Add.1
Page 5
II. Activities that have not been the subject of a full statement submitted within the set
time-frame may not benefit from the exception granted under Article 2.
III. The Minister for Labour may at all times convey to the author of the statement such
information as may seem to him to establish that the material, product or device in question, although
falling into one of the categories on the list mentioned in Article 2, does not meet the conditions laid
down in paragraph I of that same Article.  After requesting comments from the declaring party, he
may serve notice to said party to cease manufacture, processing, importation or domestic marketing
and to observe the ban instituted under Article 1.  He may make such notification public.
Article 4
The manufacture and processing of the materials, products and devices falling into the
categories on the list mentioned in Article 2 of this Decree must conform with the rules laid down
under Chapters I and II and Chapter III, Section 1 of the aforementioned Decree dated
7 February 1996.
Labelling and marking shall conform with the requirements of Article L. 231-6 of the Labour
Code and the rules established by the aforementioned Decree dated 28 April 1988.

ANNEX II
QUESTIONS – REPLIES
At the First and Second Substantive Meetings
(1-2 June 1999 and 20-21 January 2000)
I. QUESTIONS TO THE PARTIES
A. QUESTIONS AT THE FIRST SUBSTANTIVE MEETING (1-2 J UNE 1999)
1. Questions by the Panel to Canada
Question 1:  Canada states that "the risks to health associated with mo dern chrysotile products
are undetectable".  Does the concept of "undetectable" risk mean the same for Canada as no
risk?
1. The term "undetectable" should not be interpreted as a subjective judgement with respect to
risk management, but rather as a scientific term related to quantification of the risk.  In the specificcontext of its submission, Canada could just as easily have used the expression "below detection
limits" (BDL), which is commonly used by scientists.  This expression means that as determined
using the latest methods and techniques and the most rigorous statistical analysis, the risk (effect)
related to exposure conditions (type of fibre, dose, duration) is so slight, if it exists at all, as to be
"below detection limits".  Scientists generally do not use the expression "zero effect" or "no risk" orany other similar expression to describe a level of risk.  Rather, they use "below detection limits"
(BDL).  The term "undetectable" used by Canada and the scientific community at large should be
interpreted in this specific sense.  Canada considers that it is inappropriate to use expressions such as
"zero risk" or "no risk".  Canada thus adheres strictly to the scientific definition of the expression
used, i.e., not "no risk", but "undetectable risk", as indeed do the European Communities.  In fact, theEuropean Communities themselves corroborate the va lidity of this concept when they state, with
respect to ambient concentrations of asbestos in buildings, that "it is clear that the risk [thereof] is
undetectable".
Question 2:  In its oral submission (1 June) Canada indicated, with respect to encapsulated
products, that chrysotile fibres are only released under certain conditions.  What are those
conditions?
2. Products in which chrysotile is an encapsulated component release virtually no fibres
naturally, or, if they do so, in such minimal concen trations that they are below detection limits.  In
other words, only aggressive operations on products containing encapsulated chrysotile can lead to the
release of a detectable quantity of fibres.  Such operations may occur during installation, renovation or
removal of such products.
Question 3:  Do operations by professional wo rkers or private individuals on asbestos-cement
products (such as sawing, sanding or demolition) and erosion of the matrix over time have the
effect of releasing chrysotile fibres at levels that present a "detectable risk"?
3. When asbestos products are installed in the workplace, be they asbestos-cement products
(pipes, panels or tiles), friction products or other products containing encapsulated chrysotile, small
quantities of fibres may be released.  To mitigate this potential risk, numerous codes of practice such
as Standard 7337 of the International Organization for Standardization (ISO) or the American WaterWorks Association Code have been developed in order to minimize the release of dust.  These codesWT/DS135/R/Add.1
Page 8
of practice cover the tools and procedures for use with these products in detail.  Recommended
installation methods can eliminate the need to cut or drill basic chrysotile products at construction
sites, since those products are distributed in various pre-cut and pre-drilled formats to buyers'
specifications.  Where products do have to be drilled or cut, the use of appropriate tools can minimize
the release of dust and keep it well within the level considered safe by WHO.  This has beenconfirmed by laboratory tests and testing at construction sites of release of fibres during the
installation of asbestos products.

4. These workers are subject to exposure peaks, the magnitude of which depends on the
protective measures in place.  However, aside from the intensity of exposure, the duration of exposure
is also critical, for the risk is essentially determ ined by cumulative exposure.  In the United States,
according to the studies by CONSAD for OSHA (Occupational Safety and Hygiene Agency) between
1985 and 1990, the average annual exposure for such workers was 10 to 100 times higher than foroccupants of buildings with asbestos insulati on, which is corroborated by the WHO report EHC-203
(exposure of 0.002 to 0.02 f/ml).  It can be inferred that the cumulative lifetime exposure for such
workers is 2 to 30 times higher than for occupants of such buildings.  These workers therefore appear
to have a lifetime risk of some 20 to 300 per million, which is an "undetectable" risk, i.e. it cannot be
shown or measured empirically.
2
5. Unlike professional workers, private individual s probably work only very sporadically with
chrysotile cement products.  The exposure incurred by these do-it-yourself enthusiasts will only be a
fraction of that of professional workers.  Conse quently, if professional workers working on a daily
basis with chrysotile-cement products are not subject to any detectable risk, logically private
individuals will be even less so.  Generally speaking, private individuals will not perform any majoroperations such as sawing, sanding or demolition of materials.  More likely, do-it-yourselfers will
occasionally perform minor operations such as drilling a hole for a cable, for example.  Finally,
whenever they work with cement products, whether or not they contain chrysotile, do-it-yourselfers
should use simple protective measures, if only because of the presence of other carcinogenic
substances such as crystalline silica.
6. In the context of the general human environment, small quantities of fibres can also be
released through natural wear and tear of the product during its life cycle, either by mechanical
erosion of the product as a result of water or wind action or by the physico-chemical effects of
changes in temperature.  There has been extensive study of this matter, and it has been recognized that

the release of fibres is at levels which do not measurably add to the chrysotile naturally present in the
environment.  The European Communities recognize that  at such levels "it is clear that the risk is
undetectable".
Question 4(a):  What exactly does Canada me an by "modern chrysotile products" or "modern
asbestos products"?
7. By "modern chrysotile products", Canada means the range of non-friable products where:
(i) only chrysotile asbestos is used, but no amphibole asbestos (crocidolite and amosite);  and (ii) in
which the fibres are firmly bonded physically and chemically into the matrix (cement, asphalt, resins,
plastic, etc.) of the compound (chrysotile-cement, friction material, asphalt road surfacing, etc.) and
cannot easily be released in biologically significan t concentrations.  In this respect, the following
observation seems germane:
"Once an asbestos-containing product has been manufactured, whether or not it constitutes a source of
asbestos in the environment will depend to a great extent on whether or not the asbestos is firmly
"locked-in" the product with a binder, saturant, coating or bonding agent such that normal handling,
application and use do not release it.  Asbestos-cement products are a good example of "locked-in"products which probably do not constitute a significant source of asbestos to the environment under
normal conditions of use."3
Question 4(b):  Since when have "modern" as bestos processing techniques been in use?
8. The date of the shift to exclusive use of chrysotile asbestos in non-friable ("locked-in")
products varies from country to country, as do the dates on which different countries banned asbestos
flockings or the use of amphibole asbestos.  IL O Convention 162 concerning Safety in the Use of
Asbestos has now been adopted by over 20 countries.  It should also be noted that many countries
have banned or severely restricted and regulated the use of amphiboles or barred the spraying
technique as required by Convention 162, without actually acceding to it.
Question 5:  Canada observes that "the remo val of most modern asbestos products should
present little difficulty when a building is demo lished".  Can Canada expand on this assertion,
and in particular develop the concept of "little difficulty"?  In "everyday life", how can an
individual who demolishes or works on a building containing asbestos-cement detect the
presence of this material?
9. Demolition of a building is an operation which normally requires a permit and which is
usually performed by professional workers.  The issue of permits allows the authorities to ensure that
the demolition is carried out by persons who are familiar with the appropriate working methods
necessary to control all the risks associated with  demolition activities including those involving the
dust of all kinds which may be released during the works.
10. In the case of demolition of buildings, the first concern of the person responsible for the work
should be to identify the presence of friable materials such as amphibole flocking, whether that person
is a professional worker or a private individual.  Indeed, when the demolished building contains
flockings, their release into the open air will be the main source of contamination of the site by
asbestos, much more so than the presence of asbestos-cement materials.  The latter may be broken or
crushed to a greater or lesser degree, but the concentration of respirable fibres thus released will bevery much lower than concentrations of fibres originating from flockings.

No. 8, pp. 126-127 Lyon (1973).WT/DS135/R/Add.1
Page 10
11. This observation demonstrates the importance of  producing a register of buildings containing
flockings and introducing regulations requiring consultation of the register and/or inspection of
buildings to be demolished to determine whether or not flockings are present before a demolition
permit is issued.
12. When it is determined that a building contains  flockings, specific control measures must be
followed if demolition is considered necessary.
13. Otherwise, demolition of structures containing products in which chrysotile is encapsulated
(generally flat or corrugated sheeting and roof tiles) requires only elementary precautions since
chrysotile-cement debris remains largely inert.  In Quebec, for example, demolition is regulated by the
Code of Safety for the Construction Industry issued by the Occupational Health and Safety
Commission (Commission de la Santé et de la Sécurité du Travail).  The debris resulting from
demolition is disposed of in public landfill sites for solid wastes in the same way as other constructionwaste and coated with covering materials as a preventative measure, superfluous according to some,
in order to ensure that no chrysotile dust is left suspended in the air.  Under these conditions,
chrysotile-cement debris causes little or no increase  in natural concentrations of asbestos in the
environment, levels which the European Communities, it should be recalled, consider "undetectable."
Moreover, as chrysotile asbestos is not soluble and in any case constitutes no risk when ingested, ithas no effect on the local or nearby water-table.
14. Private individuals who work on a construction containing chrysotile asbestos in everyday life
run little risk since such work is very sporadic and generally of short duration, while chrysotile-related
risks are primarily associated with prolonged occupational exposure to high concentrations of fibres.
15. It should also be noted that individuals should exercise equal care when working with any
cement material, whether or not it contains chrysotile, because they are exposed to risks of the same
magnitude due to the presence of other dust, such as crystalline silica or substitute fibres which may
be released during the work.  Crystalline silica is classified as a Group I carcinogen by the  IARC and
no study has yet been carried out on the health risks associated with the inhalation of dust from
substitute fibres which may be released into the air during work of this type.
16. Wearing a "surgical" type mask would be a wise precaution whenever work by an individual
on any form of material might result in the formation of respirable dust.
Question 6:  International institutions such as WHO or ILO are encouraging a gradual switch
to substitute products (see for example ILO Convention 162 concerning Safety in the Use of
Asbestos;  IPCS Environmental Health Criteria (203) on Chrysotile, WHO 1998).  Does Canada
subscribe to this approach?
17. Canada has itself ratified Convention 162 concerning Safety in the Use of Asbestos.  The
Convention should, however, be considered in its enti rety, and it should be recalled that in Article 10,
ILO encourages a gradual switch to substitute products "where necessary to protect the health of
workers and technically practicable … by other materials or products or the use of alternative
technology, scientifically evaluated by the competent authority as harmless or less harmful."
18. To date, no comparative scientific study has conclusively shown that, under similar
conditions of production, manufacture or use, substitute products are harmless or less harmful than
chrysotile asbestos.  Indeed, some recent studies show that chrysotile displays lower biopersistence
than the main fibrous substitutes such as refractory ceramic fibres, glass fibres, aramid fibres and
cellulose fibres.  There are also numerous scientific studies in existence which show that, at the lowlevels of exposure currently observed in the chrysotile products industry (generally less than
1 fibre/ml.), there is no measurable increase in the risk to human health.WT/DS135/R/Add.1
Page 11
19. The same argument applies to the IPCS Environmental Health Criteria (203) on Chrysotile ,
WHO 1998, which states:  "where safer substitute mate rials for chrysotile are available, they should
be considered for use."4
Question 7:  What criteria should be used to determine the relative risk associated with
substitute products and chrysotile asbestos?
20. Canada has referred to the consensus that the relative risk of fibrous materials varies
according to three factors ("3 D"):  dimension, durability and dose.
21. The dimension (length and diameter) affects "respirability".  This is the factor which
determines whether a fibre can actually penetrate the confines of the respiratory system:  the alveoli.
22. However, the dimension factor is a necessary but not sufficient condition.  An inhaled fibre
must stay in the system long enough i.e. it must have sufficiently long (biopersistence) to exert its
pathogenic effect.  This is the durability factor.  In this respect, Canada has submitted (and the latest
data, which Canada can provide, confirms this) that  in inhalation experiments with animals, chrysotile
is very quickly eliminated from the lungs (within 24 to 48 hours), while amphiboles persist practicallyindefinitely, and then trigger the range of inflammatory reactions which precede and herald the known
pathologies.  The small quantity of data available on the biopersistence of certain substitute fibres (for
example aramid fibres are more biopersistent than chrysotile) suggest that the durability factor should
be seriously considered in evaluating the relative risk associated with fibres of substitutes for
chrysotile asbestos.  In this connection, the following quotation from a Scandinavian study bears
repeating:
"(…) adverse effects are associated rather with the fi bres that are retained (amphiboles), than with the
ones being cleared (largely chrysotile)" .5
23. Another study, published in 1995, indicates that:  "biopersistence of inhaled fibrous materials
is a critical factor in determining carcinogenic potency." 6
24. A recent report by Bernstein (1997) for the Joint Research Centre, Environmental Institute,
European Chemical Bureau  in Ispra (Italy) under the title  Correlation Between Short Term
Biopersistence and Chronic Toxicity Studies  confirmed the relevance of the durability factor in
evaluating the risk associated with substitute fibres and chrysotile asbestos.7
25. We had good reason to draw attention to the importance of the third factor, the dose.  It
introduces the phenomenon of the threshold of exposure above which harmful effects begin to appear,
and below which (with obvious differences according to the type of fibrous material) the risk, if any,becomes undetectable.
26. Although the "3 D" are the recognized critical factors in the risk associated with respirable
fibres, other factors;  Such as the capacity to induce the production of reactive molecular forms may
influence the degree of risk.  Indeed, as several fibre toxicity mechanisms remain uncertain, it must beensured that the experimental and epidemiological studies to evaluate the risk posed by the fibres to

humans are equally valid and comparable for chrysotile and its substitutes.  It must also be ensured
that the main comparability and validity criteria and principles for the design of such studies are
established by recognized international bodies.  We will not list these principles here, but we wish to
emphasize that comparisons of the risk associated with different fibres need to satisfy the following
conditions in order to be valid, i.e. unbiased:  (i) analysis of the structural characteristics must bebased on the "3 Ds";  (ii) the dose or exposure must be similar and must not overload the pulmonary
macrophages;  (iii) the observation periods must be similar and long enough to observe the effect of
differences in biopersistence;  (iv) the number of subjects and observations/studies must be
sufficiently large to be able to detect even a slight  risk;  (v) the characteristics of the fibres studied
must represent in the same way the real uses of chrysotile fibres and their real substitutes;  and
(vi) animal studies must study the effects of fibre inhalation in the same concentrations, under the
same conditions of exposure and using the same experimental method.
27. Only on the basis of such criteria can the relative  risk of chrysotile fibres and their substitutes
be determined, and only a comparative risk analysis such as the one defined by the National Research
Council in the United States can assess the quality and comparability of the data concerned and
estimate the relative risk of the substances.  For example, recent and incomplete toxicological data onsubstitute fibres cannot be compared with epidemiological studies based on 100 years of human
exposure.  It is necessary to compare data of the same type and of the same quality in order to have
confidence that a proposed substitute is safer than chrysotile.
Question 8:  What occupations are at greatest ri sk of exposure to asbestos at the present time?
Can protection measures be instituted - and enforced - for all these occupations?  Is controlleduse of chrysotile asbestos and products containing it possible for occupations exposed to
occasional but potentially high exposure, and exposure of a para-occupational and domestic
nature?
28. In Canada's view, the occupations which run the greatest risk of exposure to chrysotile
asbestos, are, in descending order:  (i) chrysotile miners and employees of chrysotile-ore processing
plants (mills);  (ii) workers employed in the manufacture of chrysotile fabrics;  (iii) workers employed
in the manufacture of friction linings (brakes, clutches, etc.);  (iv) workers employed in the
manufacture of chrysotile cement products;  (v) workers employed in asbestos removal;  and
(vi) workers employed in construction, renovation, maintenance and insulation.
29. While all workers in the above categories are more likely to be exposed to different types of
asbestos fibres, it is most important to note that those in categories five and six may be exposed toamphiboles, while the others are not.  In the case of workers in areas where chrysotile is used,
effective protection measures have been put in place since the 1970s by the competent authorities,
with the collaboration of manufacturers and trade unions, (ventilation, filtration, wet processes,
mechanization, etc.).  The methods used for this pur pose rely on relatively simple technologies.  They
include the following:  better ventilation of working areas;  more effective filtration of dust-bearingair;  crushing and processing under negative pressure to prevent the escape of dust;  exhaust hoods in
work stations directly exposed to fibre;  wet manufacturing processes;  mechanization, etc..
30. While workers in category 6 are exposed to friable asbestos products (of all kinds) on quite a
regular basis in the course of their work, Canada is nevertheless of the view that the same information
and training measures for employers and workers, combined with regular inspections and checks byoccupational health and safety agencies, together with the compilation of registers of buildings
containing asbestos, should give results similar to those obtained following the introduction of similar
measures for the other five categories of workers.  Prevention and protection measures (masks,
dampening, ventilation, etc.) can considerably reduce occupational exposure to asbestos.  It should be
reiterated that these working conditions stem from uncontrolled use of asbestos (mainly flockings)WT/DS135/R/Add.1
Page 13
which has not occurred since the early 1980s, and a ban on chrysotile would not in any way alter the
situation.
31. Controlled use of chrysotile asbestos and its modern products is possible for all occupations,
even those where the workers may be subject to occasional exposure.  It is a matter of establishing
and enforcing an appropriate set of rules for their use, in the same way as is done for many otherdangerous substances used in the workplace.
32. There are no conclusive studies of the risks associated with occasional but potentially high
exposure, even the French study by Iwatsubo et al. quoted by the European Communities, concurs
"(…) subjects with sporadic exposure were not at greater risk of mesothelioma than were controls."

Question 9:  Does Canada agree wi th the French experts' estimate ( Evolution of the annual
incidence of mesothelioma in Canada and Quebec, Section III.B.4), of the annual incidence of
mesothelioma in Canada and Quebec?  If not, what are the Canadian figures?  Does Canadahave statistics for deaths from lung cancer caused by chrysotile asbestos?  If yes, what do they
show?
33. The estimates of the incidence of mesothelioma  in Canada and Quebec in the first written
statement of the European Communities match the Canadian data, precisely because the InternationalAgency for Research on Cancer data are taken from Canadian cancer records.  The French experts'
analysis however, requires further explanation in order to be correctly understood.
34. Unlike France whose cancer records cover only 9.5 per cent of the population (INSERM
page 173), Canada is one of the few countries in the world whose cancer records cover 100 per cent of
the population, with the consequence that its data are more reliable than those of France or mostcountries.
9  For this reason, and because Canada has a large number of studies on cohorts of asbestos
workers, compiling a special registry of mesothelio ma cases was less pressing than in other countries.
It should be noted that France also does not have a central registry of mesothelioma.
35. Three caveats are necessary in order to interpret correctly the Canadian data summarized in
the table produced by the European Communities:  (i) Quebec cancer reports and likewise theCanadian totals that include Quebec are only reliable since 1984;  (ii) as in most countries,
mesothelioma was considerably underdiagnosed and under-reported until the mid-1980s, which
falsely inflates the increase in the incidence of mesothelioma during the 1970s and 1980s
10;  (iii) data
and trends prior to 1984 should therefore be treated with caution.

9 That is why Dr. Julian Peto had to estimate the incidence of mesothelioma in Western Europe from
data on mortality from cancer of the pleura, a very imperfect indicator of the incidence of mesothelioma.

36. Recent analyses of Canadian data on mesothelioma in Canada11, British Columbia12 and
Quebec 13-14 agree that rates of incidence of mesothelioma have been stable in women of all age
groups since 1984.  In Quebec, the rates are 70 per cent higher than elsewhere in Canada, probably
because of more frequent and more intense exposure in the workplace.  In fact, Quebec produced
about half of the world's commercial chrysotile until the 1950s.  Quebec also used large quantities ofamphiboles in various sectors, particularly in certain sectors in which many women were employed,
especially during the Second World War.
37. According to a study by Schanzer, Semenciw and Ugnat (Health Canada, 1997), the incidence
of mesothelioma in men in Canada increased by 22 per cent from 1984 to 1993, half the increase
estimated by the French experts, and also half that in France.
15  Over the same ten-year period, the
incidence of mesothelioma rose by 45 per cent in Quebec (the same as in France), 34 per cent in
Ontario, 0 per cent in British Columbia and less than 10 per cent for the rest of Canada.  These ratesreflect wide disparities in Canada, contrary to the European Communities' assertion.  The incidence in
men also levelled off in 1984 in British Columbia (according to Coleman and Philips), and seems to
have levelled off in Quebec after 1990.
38. Finally, the analysis of Canadian rates between 1973 and 1992 (Schanzer and colleagues,
1997) estimates that the risk is four times higher for men born before 1940 than for those bornbetween 1951 and 1955.  These analyses therefore suggest that the incidence of mesothelioma has
levelled off in Canada is declining in Brit ish Columbia, and has levelled off in Quebec.
39. The following table, adapted from the one submitted by the European Communities, shows
that despite the much higher asbestos production in Canada and Quebec than in France, the incidence
of mesothelioma and the increase in that inciden ce were lower in Canada than in France.  Thus,
although Quebec produced almost half the chrysotile used in the world, the incidence of
mesothelioma in Quebec was, surprisingly, no higher than in France.

15 Our comparison with France reflects the fact that the statement of the European Communities
incorrectly calculated the rate of growth for Canada as "a particularly high rate".  However, as shown on page177 of the INSERM Report, the incidence of mesothelioma rose more rapidly in France than in Canada.

40. With respect to the proportion of lung cancer cases attributable to occupational exposure to
asbestos, no country in the world possesses such statistics.  However, case-control studies of a number
of cancers and types of exposure in the general population in Canada (some metropolitan regions or
provinces) suggest an upper limit to the proportion of lung cancer cases attributable to asbestos, but
they suffer from flaws which make it impossible to determine the specific proportion that is due toasbestos, independently of other major risk factors.
41. A case-control study of cancers in Montreal
17 suggests that the specific association between
lung cancer and asbestos would explain at most 7.6 per cent of lung cancers in men between 1979 and
1985;  but the real proportion is lower because part of the 7.6 per cent is attributable to concomitant
exposure:  PAHs (polycyclic aromatic hydrocarbons), solvents, alkanes, welding fumes, tobacco
(residual effects after statistical control), etc.
42. Case-control studies in the United States, the United Kingdom and Sweden provide other
estimates of the percentage of lung cancers attributable to asbestos.  As the review of the studies18
cited by INSERM (pages 10 and 179 of the Report) indicates, the enormous heterogeneity of thesestudies (e.g. the attributable percentage ranges from 0.6 per cent to 16.6 per cent in the
United Kingdom alone) stems from variations in the prevalence of asbestos exposure (types of
industry and proportion of workers exposed), which prevents any extrapolation of their findings toCanada (or to France).
Question 10:  Canada refers to the WTO report Environmental Criteria 53:  Asbestos and Other
Natural Mineral Fibres, published in 1986, but does not mention a subsequent report by the
same organization, IPCS Environmental Health  Criteria (203) on Chrysotile, in 1998.  In
Canada's view, to what extent does the 1998 report confirm the findings of the 1986 report,particularly with regard to the dangers of chrysotile and risk management methods?
43. The reply to this question should be prefaced by two preliminary remarks.  Firstly, it should
be recalled that the forewords to the above-mentioned reports read as follows:  "[T]his report contains
the collective views of an international group of experts and does not necessarily represent thedecisions or the policy of the United Nations Environment Programme, the International Labour
Organization, or the World Health Organization."  Secondly, Canada wishes to emphasize that the
interpretation of the two reports, each over 150 pages long, in the limited context of the reply to this
question will necessarily be incomplete.
44. That being so, this reply will address the question of the dangers of chrysotile before turning
to risk management methods.  Report 203 surveys the data on exposure to chrysotile and suggests
among other things that:  (i) in the mines and mills in Quebec, "the average fibre concentrations (…)are now generally well below 1 f/ml":  (ii) in the production of asbestos cement in Japan,
concentrations range between 0.05 and 0.45 f/ml in 1992;  (iii) in the production of textiles in Japan
between 1984 and 1986, the concentrations found were between 0.1 and 0.2 f/ml;  (iv) in other
countries and various other sectors:  vehicle maintenance:  "practically all measured levels after 1987
were less than 0.2 f/ml";  buildings maintenance:  "[I]n buildings with control plans, personalexposure of buildings maintenance personnel in the USA … between 0.002 and 0.02 f/ml."
19  Th e
trend towards lower concentrations is thus confirmed, and demonstrates the feasibility and benefits of
applying controlled use policies.

Page 16
45. Report 203 also recognizes the difference in the dangers associated with chrysotile and
amphiboles:
"The mechanisms of the relatively more rapid clearance of chrysotile fibres compared to those of
amphiboles (…)"
"The more rapid removal of chrysotile fibres from the human lung is further supported by findings
from animal studies ( … )"20
46. Report 203 recognizes that the presence of chrysotile fibres in water is harmless:
" … it was concluded that there was little convincing evidence of an association between asbestos in
public water supplies and cancer induction.  Mo re recent identified studies do not contribute
additionally to our understanding of health risk associated with exposure to chrysotile in drinking
water."21
47. None of the IPCS reports (EHC No. 53 and 203) suggests any measures whatsoever with
respect to risk management methods:
The EHC monographs are intended to assist national and international authorities in making risk
assessments and subsequent risk management decisions.  They represent a thorough evaluation of risks
and are not, in any sense, recommendations for regulation or standard setting."22
48. Thus among the conclusions in the 1998 report, we read:  "[W]here safer substitute materials
for chrysotile are available, they should be considered for use."23  It is clear from this latter extract that
the scientists who wrote the EHC 203 report refer to the consideration of safer and available substitute
material.  On the issue of proven safer substitute fibres, Canada has already indicated in its written
and  oral submissions that none of the fibrous materials that have been proposed as substitutes have
undergone rigorous tests to show that they are harmless.  The limited data at present availablesuggests that premature replacement could be a serious risk management error.  This last extract refers
to available substitutes.  Experience shows that the mere fact that such materials are available does not
mean that they are technically adequate.  Finally, the recommendation does not say that asbestos
should be replaced, rather that replacement "should be considered".  The 1998 WHO report thus
confirms the 1986 report.  Both emphasize a reduction in fibre concentrations, recognize thedifference between chrysotile and amphibole and su ggest replacing chrysotile by safer substitutes.
However, as Canada submits, the fibre substitutes have never been subjected to rigorous tests that
demonstrate them to be harmless.
Question 11:  Does Canada accept the logic that an increase in a country's imports of chrysotile
asbestos is accompanied by a proportional increase in asbestos-related pathologies?
49. Canada does not accept the "logic" that an increase in a country's imports of chrysotile
asbestos is accompanied by a proportional increase in asbestos-related pathologies.  Indeed, this
"logic" only holds up if one ignores the marked differences in risk between different types of asbestos,
between friable and non-friable products, between sanitary and unsanitary conditions and between the
production, use and presence of asbestos products.
50. It is recognized that the health risks associated with asbestos are primarily a function of the
"three Ds":  dose, dimension, durability (biopersistence).   The volume of asbestos imports bears little

or no relation to these risk factors.  Rather, specific information should be provided for each country
on the following:  the proportion of workers exposed, the conditions of exposure (types of industry
and products, workplace hygiene regulations) product uses and distribution in various population
groups (brakes, flockings, construction materials, cement, public buildings, etc.), the types of asbestos
used and their applications.  These conditions vary greatly from country to country and over time.
51. No analysis can distinguish the impact of asbestos imports by type of fibre for the following
reasons:  (i) the available data do not normally allow us to distinguish retrospectively between the
mineralogical types of imported asbestos;  (ii) even if such information were available, it would not be
possible to distinguish the effects based on mineralogical type of asbestos because the volumes of
imports of chrysotile and amphiboles are closely correlated (i.e. historically, the more chrysotile that
was imported, the more amphiboles were imported too);  and (iii) there are paradoxes, such as
countries which produced chrysotile while also importing amphiboles to satisfy their industrial needsof the time.
52. Furthermore, importing a small quantity of amphiboles for uncontrolled use, in flockings, for
example, would probably lead to a measurable increase in pathologies.  On the other hand, an increase
in the chrysotile imports for controlled use in the manufacture of non-friable products in a context of
controlled utilization would not result in any detectable additional risk.
53. As for the type of fibre, three recent studies examined the relationship between asbestos
imports and mesothelioma in three countries:  the United Kingdom
24, the United States25 and France.26
None of these studies addressed the link between ch rysotile imports and mesothelioma.  Moreover, in
the most recent of these studies, conducted by French researchers, the authors explain that their
estimate of the incidence of mesothelioma in Fran ce is much lower than that predicted using  Peto's
model for Great Britain because of the type of asbestos and not the imports:
"a possible explanation can be found in the different fibres used in this country;  France used a much
smaller proportion of amphiboles than Great Britain."27
54. As for the level of exposure and the difference between workers and the general population,
the French experts explain that there was no increase in mesothelioma among women, despite an
increase in production and imports over time, because of the low levels of environmental exposure:
"This does not support the hypothesis that current environmental exposure to asbestos could be
associated with detectable risk of death."28
55. It should be noted, incidentally, that, like Canada, the French experts use the concept of
"detectable risk".  This "logic" also does not take account of the variety of ways that asbestos is used
or the way its use has evolved.  For example flockings in the 1960s and 1970s, must have
significantly increased the risk of mesothelioma for a given volume of consumption or imports.
Neither does this "logic" hold good for countries/regions such as South Africa, Brazil, Quebec andWestern Australia, which are asbestos producers but import little, since the proportion of their
populations exposed in the workplace and the levels of exposure were higher than in most importing

countries and often led to higher risks of pathologies than in countries/regions that import more
asbestos.
56. Technically speaking, what the Panel and the European Communities call "logic" consists of
an error of inference which is classic in epidemio logy, the social sciences and biostatistics:  the
ecological fallacy.  This fallacy consists of confusing observations of large groups (aggregates)showing non-specific aggregate correlations with real individual effects.  In particular, it consists of
ignoring the fact that the conditions of exposure and "co-factors" (other risk factors) for individuals in
the varions large aggregates vary enormously.  These big observation units are so broad that they are
in fact not comparable or similar when it comes to the factors which actually determine the risk.
57. Thus, in the case of chrysotile, the study and graph by Takahashi et al  cited by the
European Communities do not distinguish between the effects of chrysotile and those of asbestos;
separate graphs are needed for the consumption of chrysotile and amphiboles.  In fact, similar graphsand correlations to those of Takahashi would be obtained for the consumption of artificial fibres or
consumption of cement.  What should one deduce from that?
58. Crude ecological correlations lend themselves to arbitrary and contradictory interpretations.
There are only ten countries in the graph, which is too few:  the sample, selection criteria or their
characteristics skew the analysis.  If another twenty countries were added, including Quebec,South Africa and Western Australia, the picture would be more representative but much less coherent,
the correlation would be weaker and the line would be flatter.  Indeed, to fit a straight line between
these ten points is arbitrary.  The best correlation with Takahashi's ten points is not a straight line but
rather an "S-shaped" curve (e.g. logistic or cumulative normal curve), with a practical risk threshold
(no risk for consumption below 1 kg./capita/year) and a risk ceiling (no additional risk forconsumption over 2.5 kg./capita/year).  It is no more absurd to argue for this interpretation than for a
linear relationship.  We are not saying that these data show a risk threshold, but wish to underline the
arbitrary nature of the European Communities' interpretation of these ecological data.
59. For lung cancer, the significance of smoking and other risk factors, means that there is even
less reason to deduce a proportional risk relationship with a country's asbestos imports orconsumption levels.
60. In short, there is no clear-cut link between asbestos imports (particularly chrysotile) and the
incidence of asbestos-related pathologies.
Question 12:  Does Canada agree with the Eu ropean Communities that cellulose, polyvinyl
alcohol and aramid fibres have been shown to be safe or of low toxicity?
61. No.  Canada does not agree that cellulose, PVA and aramid fibres have low toxicity.
62. The European Communities claim that the diameter  of these fibres is generally greater than
that of chrysotile fibres.  This can probably be explained by the data on "nominal diameter" supplied
by the substitute fibre industry.  For example, in the case of aramid fibres, the "nominal diameter" is
from 12 to 15 microns.  However, there are data which show that in commercial preparations of fibres
labelled "nominal diameter:  12-15 microns", there is a significant proportion of fibres with a diameterwithin the range of respirable diameters.
29  The presence of such fibres has even been observed in the
pulmonary alveoli of laboratory animals which ha ve been exposed to commercial preparations.
63. Furthermore, as the IPCS-EHC Report No. 151 states on page 76:

Page 19
"All fibres that are respirable and biopersistent mu st undergo testing for toxicity and carcinogenicity.
Exposures to these fibres should be controlled to the same degree as that required for asbestos until
data supporting a lesser degree of control become available.  The data available suggest that para-
aramid fibres fall within this category.   Furthermore, other respirable organic fibres should be
considered to fall within this category until data indicating a lesser degree of hazard become
available."30
64. In addition, the claim that the fibres are less "biopersistent" is arguable.  As the authors of the
INSERM report recognize, there are few verifiable data on this subject.  As stated in INSERM's
summary report - Effects on Health of Substitute Fibres for Asbestos :
"The results of many studies suggest that the 'fibrous' structure of asbestos is a significant pathogenic
factor in the same way as some of its chemical characteristics.  Consequently, any new fibre proposedas a substitute for asbestos or for any other purpose, must be suspected, a priori, of being pathogenicbecause of its structure, which does not preclude the analysis of other possible consequences of its
physical and chemical characteristics".
31
65. This view is echoed by the Scientific Committee on Toxicity, Ecotoxicity and the
Environment of the European Commission (DG XXIV) which stated:  "for the substitute materials,
with the exception of vitreous fibres, there is no significant epidemiology base to judge the human
health risks".32
66. Canada is prepared to prove that, in fact, aramid fibres are more durable and biopersistentthan chrysotile fibres.
67. Canada shares the opinion of the experts that fibres replacing chrysotile should not be
assumed to be harmless until all relevant data have been collected.  The authors of the INSERM
Report are equally circumspect on this point.
Question 13:  In paragraph 238 of its first written submission, Canada states that Article 2.4 of
the Agreement on Technical Barriers to Trade lays down the principle that a Member "shall
use relevant international standards, or the rele vant parts of them, as a basis for their technical
regulations".  In paragraph 249 of its submissi on, Canada further states that the Decree does
not comply with international standards (… )".  Does Canada consider the concept of
regulations "based on" or "in accordance with" an international standard to be equivalent to
the concept of using internationa l standards or relevant parts of them "as a basis" for their
technical regulations, within th e meaning of Article 2.4 of the Agreement on Technical Barriers
to Trade?
68. No.  Under Article 2.4 of the TBT Agreement, France is required to use relevant international
standards or parts of them as the basis or foundat ion of its technical regulations.  In paragraph 249 of
its first written submission, Canada merely observes that the Decree does not comply with
international standards.  In paragraph 249 of its first oral submission presented at the first substantivemeeting, Canada maintained that "Article 2.4 should not be interpreted as allowing a Member to
circumvent a complete series of international standards that provide the foundations – sometimes
quite specific – for a measure enabling Members to fulfil the alleged objective".  In paragraph 250 of

the same oral submission, Canada adds the following:  "the French measure deviates significantly
from the precepts of international standards".  In ot her words, the French measure deviates to such an
extent from the fundamental principles of international standards that the latter are no longer
recognizable.
Question 14:  Is there any difference between the concept of using international standards "as a
basis" for a technical regulation within the meaning of Article 2.4 of the Agreement on
Technical Barriers to Trade and the concept of a technical regulation "in accordance with
relevant international standards"  within the meaning of Article 2.5 of the same Agreement?
69. Yes.  As the Appellate Body reported in its Report on European Communities Measures
Concerning Meat and Meat Products (Hormones) , there is a difference between the meaning of the
terms "based on" and "conform to".  In paragraph 163 of the Report, the Appellate Body stated that:
"[…] the ordinary meaning of 'based on' is quite different from the plain or natural import of 'conform
to.'  A thing is commonly said to be 'based on' another thing when the former 'stands' or is 'founded' or
'built' upon or 'is supported by' the latter.  In contrast, much more is required before one thing may be
regarded as 'conform[ing]' to 'another':  the former must 'comply with' 'yield or show compliance' with
the latter.  The reference of 'conform to' is to 'correspondence in form or manner' to 'compliance with'
or 'acquiescence', to 'follow[ing] in form or nature.'  A measure that 'conforms to' and incorporates a
[given standard] is, of course, 'based on' that standard.  A measure, however, based on the standard
might not conform to that standard, as where only so me, not all, of the elements of the standard are
incorporated into the measure." [Footnote omitted]
70. Article 2.4 of the TBT Agreement lays down the obligation to use relevant international
standards or relevant parts of them as the basis of technical regulations.  According to the ordinary
meaning of words, this means that technical regulations must be founded on international standards or
relevant parts of them.  In other words, technical regulations must have as their fundamental principleor point of departure what is set out in international standards.  This does not mean that the technical
regulations adopted by a Member must be identical to international standards but where the latter are
relevant, the technical regulations should be prepared on the basis of those international standards:
the underlying international standard must be recognizable on a reading of the measure.  Canada has
established that the international standards concerning asbestos are relevant.  The European
Communities have not offered any convincing evidence to the contrary.  In this instance, the French
measure strays so far from the international standa rds that they are no longer recognizable as the
foundation.  The European Communities have not offered any reason to justify this departure and
consequently the disputed measure is in contravention of Article 2.4 of the TBT Agreement.
71. Given that the Decree deviates to such an extent  from the international standards that they are
not evident as its basis, the European Communities cannot claim that "[…] it must be concluded (sic)that the international texts quoted, or sometimes not quoted, by Canada serve 'as a basis' for the
French decree."
72. Furthermore, the obligation to use international standards as the basis for preparing technical
regulations should not be interpreted as permission simply to ignore important aspects of those
standards, as France has done.  France is, in effect, forcing the replacement of asbestos by substitutes,ignoring the fact that it is only in the event of  necessity that such replacement is recommended and
only where the substitutes are harmless and safe.  France has quite simply ignored the test of
"necessity" required by the international standards and reports in order to operate a policy of banning
asbestos.  This is particularly disconcerting when it is considered that these are the same standards and
reports that are cited by the European Communities to justify the French position in paragraphs 531et seq . of their submission and that those standards and reports are very specific in this respect.WT/DS135/R/Add.1
Page 21
73. For its part, Article 2.5 of the TBT Agreement establishes a rebuttable presumption when the
measure is in accordance with international standards.  The French measure is clearly not in
accordance with international standards.  In this  instance, therefore, the European Communities
cannot rely on the presumption in Article 2.5 of the TBT Agreement.
Question 15:  Canada states that it "will us e the example of chrysotile fibre and chrysotile
cement in order to show that chrysotile fibre and substitute fibres are similar and products
containing chrysotile and those containing substitute fibres are like products".  In the light of
this paragraph and the overall arguments presented by Canada in its analysis of the similarity
of products under Article III:4 of GATT 1994, is our understanding correct that Canada does
not allege any likeness between chrysotile fibres and products containing chrysotile and any
possible non-fibrous substitute products?
74. Yes.  Both under Article III:4 of GATT 1994 and Article 2.1 of the TBT Agreement, Canada
is not invoking the argument of the likeness of non-fibrous substitute products (PVC, ductile iron).
Nor does Canada extend the likeness argument to substitute fibres other than glass, cellulose and PVA
fibre or fibro-cement products containing these types of fibre.
75. Canada does not need to invoke all products like to chrysotile or chrysotile cement products
to demonstrate a violation of Article III:4 of GATT 1994 and Article 2.1 of the TBT Agreement.  For
there to be a violation, it simply has to show that for a given product or series of given products there
are one or more like products which enjoy more favourable treatment.
76. We wish to point out that in rejecting the analysis of likeness advanced by Canada, the
European Communities go to great pains to affirm that PVC and ductile iron are not products "like"chrysotile fibre and chrysotile cement products.  Interesting as it may be, however, this analysis is in
no way relevant to the issue of whether glass fibre, cellulose fibre, PVA fibre and fibrous-cement
products incorporating these types of fibres are "like" chrysotile fibre and chrysotile cement products.
Question 16:  In its argument concerning Articl e 2.2 of the Agreement on Technical Barriers to
Trade, Canada maintains that the ban on asbestos and products containing asbestos has no"rational link" with the objective pursued by France.  Could Canada provide additional
clarification on the distinction between this concept of "rational link" and the test of necessity
which it defines as the second test of a measure's conformity under Article 2.2?
77. Canada maintains that a technical regulation creates an unnecessary obstacle to international
trade if the objective of the regulation is not legitimate or if the regulation is more restrictive than
necessary to fulfil its objective, taking account of the risks non-fulfilment would create.
78. Once an objective is recognized as legitimate, it is then a matter of determining whether the
technical regulation is a rational and necessary measure.  The nature of the "rationality" and
"necessity" of a technical regulation may vary according to the circumstances.
79. In our view, rationality and necessity entail the following elements.  Firstly, the technical
regulation must be carefully conceived to fulfil the objective concerned.   It must be neither arbitrary,nor founded on irrational considerations.  That is the rational link.  Secondly, even supposing that
there is a rational link, the technical regulation must be such that it is not more trade-restrictive than
necessary to fulfil a legitimate objective, taking account of the risks non-fulfilment would create.
These are the risks entailed by the absence of a technical regulation and minimum prejudice to trade.
80. With regard to the rational link, the point is whether the technical regulation is rationally
linked to the fulfilment of the objective.  In other words, is the technical regulation carefully designed
to fulfil the objective in question.  We feel that this stage of the analysis is essential in order to avoidWT/DS135/R/Add.1
Page 22
justification of technical regulations which have tenuous links with the intended objective or even
none at all.  If this were not a necessary stage, a great many technical regulations could be justified
without the slightest link with the objective.
81. With regard to the risks of having no technical regulations and minimal effect on trade, it is
first necessary to try and establish if the absence of a technical regulation would create risks that theobjective would not be fulfilled.  To evaluate these risks, the relevant factors to be considered include
scientific and technical data available and the intended end-uses of the products.  One must then ask
whether the prejudicial effects of the technical regulation are appropriate given the objective, in short,
whether there is a less trade-restrictive alternative solution which would allow the intended objective
to be fulfilled equally well.
82. It is only once the rational link between a technical regulation and the legitimate objective has
been established that there is reason to examine the risks that might be created by the absence of thattechnical regulation and the existence of an alternative measure.
2. Questions by the Panel to the European Communities
Question 17:  The EC states that "between  1945 and 1988, some 97 per cent of the asbestos
consumed by France was chrysotile asbestos.  Fr om 1988 onwards, all the asbestos consumed in
France was chrysotile asbestos".  What has been the pattern of consumption of hard and friable
forms of chrysotile asbestos in France since 1945?
83. The question contains an ambiguity that needs to be removed.  Thus, it is necessary not to
confuse:  (i) the variety of the fibres:  there are different natural varieties of asbestos, in particular, thechrysotile variety which should be distinguished from the amphiboles.  These fibres are incorporated
in materials:  (ii) the "friability" of materials containing asbestos:  these materials may be hard or
friable, in varying degrees, depending on the application.  In the French regulations, the friability of a
material containing asbestos is defined as follows:  "A friable material is any material liable to emit
fibres under the influence of impact, vibration or air currents."  Flocking (material composed of a matof blown fibres) and lagging consisting of asbestos wadding or felt are typical friable materials.
Asbestos-filled plastics and asbestos-cement products are non-friable materials.  Before amphiboles
were banned in the countries of the European Union, as in many other countries, there may have been
friable products based on chrysotile and non-friable products based on amphiboles, and vice versa.  It
would be quite mistaken to associate amphiboles exclusively with friable products such as flocking
and lagging and chrysotile exclusively with non-friable products such as asbestos cement.  Since
amphiboles were banned, all products containing asbestos - both friable and non-friable - have beenbased on chrysotile.
84. With regard to trends in asbestos fibre consumption and the division of the market between
friable and non-friable products, the data supplied by the asbestos-processing industry indicate that
over the period 1970-1975 (when both amphiboles and chrysotile were in use):  (i) asbestos intended
for very friable products (flocking, wadding), which do not form part of the statistics of the asbestos-processing industry, accounted for 10 to 20 per cent of imports;  (ii) the remaining imports (80 to
90 per cent of the total), intended for processing, can be broken down as follows:
Non-friable products:
- 73 per cent for asbestos cement (compared with over 75 per cent in 1950);
- 8.4 per cent for floor coverings (production increased seven-fold between 1950 and
1975);
- 3 per cent for brakes (production increased seven-fold between 1950 and 1975);
- 1.9 per cent for mouldings (stable between 1950 and 1975);WT/DS135/R/Add.1
Page 23
- 1.3 per cent for gaskets;
- 2.4 per cent for miscellaneous applications (adhesives, mastics, mortars, etc.).
Friable products:
- 7 per cent for asbestos board and paper;
- 3 per cent for textile products (braiding, tape, coverings, etc.).
85. The use of very friable products (asbestos flocking and wadding) ended in France in 1978.
No more asbestos fibres were incorporated in floor coverings after 1984.  In the 90s (before the ban),
asbestos-cement products, brakes and mouldings accounted for more than 90 per cent of the asbestos
imported.  Friable products such as textiles and board consumed less than 10 per cent.
Question 18:  The European Communities state that Canada "consumes little asbestos and thus
exports the bulk of its production".  The European Communities also note, in paragraph 53:
"... the fact that the increase in the frequency of mesothelioma-type cancers can be seen
throughout Canada shows that the risk of death from chrysotile is not confined to the asbestos
mining industry ... but that it affects all sectors of the economy".  To which sectors of theeconomy do the European Communities refer?  Are statistics and studies available?
86. Per capita consumption in Canada is among the highest in the industrial world.  Canada
exports most of its chrysotile asbestos product ion (400,000 tonnes out of 4 50,000 in 1990).  Thus, the
proportion reserved for home use is very small.  Nevertheless, Canada's consumption is veryconsiderable compared with other industrialized countries.  Thus, in 1990, per capita consumption in
Canada was distinctly higher than in France:  (i) Canada:  2.05 kg per capita;  (ii) Brazil:  1.26 kg. per
capita;  (iii) France:  1.11 kg per capita;  (iv) United States:  0.13 kg per capita.  This high level of
asbestos consumption in Canada explains the high and steadily increasing incidence of mesothelioma
in that country.
87. There are studies available which show that in Quebec and the other areas investigated a wide
range of economic sectors is affected by mesothelioma.  Thus, a study by Siemiatycki
33 in Montreal
shows that the workers mainly at risk of mesothelioma are those exposed while working with
materials containing asbestos.  The results of the study show that construction sector workers run a
risk of developing mesothelioma almost 12 ti mes higher than the average.  Another study34 by the
Quebec Occupational Health and Safety Commission (CSST), reveals that the risk of mesothelioma
has increased steadily in Canada since 1967.  The study notes that the incidence of this disease isincreasing especially rapidly in the maintenance sector.
Question 19 :  With respect to substitute products, INSERM has stated, in particular, that
"suitable research work should be carried out and developed as a matter of urgency, before
substitute fibres are generally introduced" (Effects on health of the main types of asbestos
exposure, INSERM, 1997, p. 434) and that "t aking into account the present uncertainties
concerning the effects on humans of exposure to fibres used as a substitute for asbestos, it is
important to ensure that the levels of exposure among users of products containing fibre
substitutes for asbestos are as low as possible" (Effects on health of fibres used as a substitute
for asbestos, INSERM, 1998, p. 34).  In the light of these observations, can the European
Communities explain the statement in paragrap hs 140 et seq. of their written submission
according to which "there are no data giving rise  to concern as to the carcinogenicity of fibres
used as a substitute for asbestos in cement fibres"?

Medicine 22:531-542 (1992).WT/DS135/R/Add.1
Page 24
88. There are no data giving rise to concern as to the fibres used as a substitute for asbestos in
cement fibres.  First of all, it should be noted that asbestos cement is often replaced by products from
another branch of technology (PVC plastics, ductile iron, various metals, etc.).  This is the case, in
particular, with pipes and roofing.  In France, industry had decided to stop producing asbestos-cementpipes before the ban, because of the competition from PVC and ductile iron.  When asbestos is
replaced in fibro-cement, it is replaced by PVA, para-aramid or cellulose.  It is never replaced in
fibro-cement by man-made mineral fibres.  PVA, cellulose and para-aramid fibres have been used for
a very long time without any sort of health warning having been given by occupational health
specialists.  PVA fibres have been used since 1930, para-aramid fibres for 30 years or so.  As for
cellulose, it has been in use for several centuries.
35
89. In 1996, these substances gave no cause for concern, and this has since been confirmed by
studies conducted by CSTEE DG XXIV of the Commission of the European Communities and COC36
in the United Kingdom.37  Moreover, by the time the decision to ban asbestos was taken (July 1996),
key facts had become available as a result of the G2SAT report on the comparative harmfulness of
asbestos and man-made mineral fibres.38  This report established a hierarchy of risks as between
chrysotile asbestos, ceramic fibres and mineral wo ols (glass wool, rock wool, slag wool) which made
it impossible to avoid a global ban with exceptions.39  Thus, in 1996, France had to choose between
asbestos, a known and proven human carcinogen, and substances used for decades without any
problem ever having been reported.
90. INSERM's concerns relate to certain man-made mineral fibres rarely used as substitutes for
asbestos and France has taken INSERM's recommendations into account.  The expert opinionrequested from INSERM related mainly to the fibres most under suspicion, i.e. man-made mineral
fibres (ceramic fibres and mineral wools), whose harmfulness had been stressed by the opponents of a
ban on asbestos.  It confirmed the results of the G2SAT Report, as well as the classification adopted at
the European level for ceramic fibres and mineral wools.  France took into account the
recommendations to proceed with caution and proposed an action plan for consideration by the socialpartners as soon as the results were published:  (i) reminder of the regulations applicable, given the
European classification;  (ii) controls on fibre labelling;  (iii) package of measures to monitor
exposure levels, in particular among secondary users;  (iv) establishment of groups of workers
exposed to man-made mineral fibres for epidemiological follow up purposes.
Question 20 :  Why did asbestos cement remain outside the scope of Directive 91/659/EEC
(paragraph 82 of the first submission of the European Communities)?
                                                     
35 We recall that, where asbestos is concerned, the first findings of its harmful effects on health go back
to 1906, as attested by the report of a French labour inspector who drew attention to the number of deaths
among workers who had worked in factories making asbestos-based products.
36 Opinion on chrysotile asbestos and possible substitute products, Scientific Committee on Toxicity,
Eco-toxicity and the Environment (CSTEE), 19 September 1998;  Statement for Health and Safety Executive
(HSE) on Carcinogenic Risks of Three Chrysotile Substitutes, Committee on the Carcinogenicity of Chemicalsin Food, Consumer Products and the Environment (COC), July 1998.
37 At this point, we note that asbestos cement accounted for 90 per cent of the asbestos imported into
France at the time of the ban. Thus, in accordance with INSERM’s recommendations, France has notgeneralized the use of man-made mineral fibres in place of asbestos.
38 Used much less frequently as a substitute for asbestos (less than 10 per cent of the asbestos used in
France).
39 This hierarchy of risks showed that chrysotile asbestos (a proven human carcinogen) poses a much
greater threat than ceramic fibres (a suspected animal carcinogen) and a fortiori  mineral wool (no carcinogenic
effect on animals, no effect on the human lung).WT/DS135/R/Add.1
Page 25
91. The purpose of the 1991 Directive 91/659/EEC was to ban, on the basis of the
epidemiological data available at the time40, all varieties of asbestos other than chrysotile, which was
then considered less dangerous than amphiboles.  This directive also restricted the use of chrysotile to
those products which were incapable of releasing asbestos fibres spontaneously into the air without
special intervention and for which the possibilities of replacement had not yet been fully established.Since the publication of that directive, our understanding of the risk and the international database
have expanded considerably
41 and research on the replacement of the asbestos in asbestos cement
products has led to solutions that pose no threat to the health of the user and are technically and
economically viable.
Question 21:  Is it possible to estimate the number of deaths, since 1945, due to chrysotile
asbestos occurring in the categories which the submission of the European Communities
described as "secondary" occupational, para-occupational and domestic? What type ofexposure is responsible for the 25 per cent of  mesothelioma cases in the building sector
mentioned in paragraph 413 of the submission of the European Communities (construction,
occasional handling, de-flocking, demolition, etc.)?
92. The number of deaths by mesothelioma among "secondary" users can be estimated at between
10 and 15 per million inhabitants per year.  For mesothelioma, the spontaneous death rate, i.e. other
than by exposure to asbestos, is about one to two cases per million inhabitants per year.  It is true that,
up to about the 1970s, the great majority of these deaths occurred among primary users (asbestos
mining and processing).
42  During that period the rate reached about five cases per million inhabitants
per year in most of the industrial countries for which reliable health data are available (see Table 4,page 166 of the INSERM Report.  All the studies show that those affected were almost exclusively
so-called "secondary" users.
43  The study by J. Peto et al.44 analyses mesothelioma mortality in
England and Wales during the years 1979 to 1990.  It shows that about 95 per cent of all the deaths
that occurred during that period concerned workers belonging to the "secondary" user group.  In the
industrial countries, this proportion of 95 per cent of all asbestos-related deaths has applied to thiscategory of workers since about the 1970s.  At present, among men, the mesothelioma death rate
stands at about 15 to 20 deaths
45 per million inhabitants per year:  thus it may be estimated that in
these countries 10 to 15 deaths per million inhabitants per year occur among male workers in the
"secondary" user category.46  Even if a small fraction of these deaths can be attributed to exposure to
amphiboles, it is none the less true that the number of deaths due to chrysotile is quite considerable.
93. The overwhelming majority of mesotheliomas occurring among construction workers are the
result of occasional exposure to high peaks of asbestos.  This can be illustrated by reference to thetable headed "Distribution of Deaths from Meso thelioma by Occupation (Section III.B.4)" which
gives a breakdown of the occupations most affected:  the construction sector trades most affected are
the carpentry, plumbing, electrical and related trades.  Typically, workers in these trades have to
                                                     
40 The data on which an international concensus was reached in 1991 came from studies and
observations made at least four or five years earlier.
41 With the exception of the G2SAT study, the scientific studies appended to the first written
submission of the European Communities are all post-1991.
42 In fact, because this disease has a very long late ncy period, the deaths that occurred up to the 1970's
correspond to exposures suffered prior to about the 1940's, when asbestos was still little used.
43 Because of the long latency period, it took several decades for the asbestos marketed on a large scale
after the Second World War to produce its effects on large numbers of "secondary" users.
44 J. Peto et al., Continuing Increase in Mesothelioma Mortality in Britain, The Lancet, vol. 345,
page 535 (1995).
45 It should again be pointed out that this estimate should be at least doubled  to take into account the
deaths by lung cancer and the cases among women, which are less numerous.
46 According to recent estimates, in the next 30 years about 500,000 men will die in Western Europe
and 95 per cent of these will be workers in the "secondary" user category.WT/DS135/R/Add.1
Page 26
handle asbestos-containing materials only intermittently.  This is because of the numbers involved.47
To the workers in these construction trades it is necessary to add the workers in many other
occupations:  welders, dockers, laboratory technicians, fitters, upholsterers, power station workers,
etc., who are only occasionally exposed to high peaks of asbestos and, taken together, account for the
majority of deaths by mesothelioma.
Question 22:  The article annexed by  the European Communities (A. Gilg, et al.,  Estimation of
the Past and Future Burden of Mortality from Mesothelioma in France , Occupational
Environmental Medicine, 1998;  55:  760-765) estimates that between 1996 and 2020, about
20,000 men will die of mesothelioma.  Is it possible to determine the different circumstances of
exposure to asbestos that will have i nduced these 20,000 cases of mesothelioma?
94. Occupational exposure to asbestos in France concerns the approximately 20-25 per cent of
men who have been exposed at least once in the course of their working life.48  This reflects the
enormous variety of exposures.  In France about 85 per cent of all the men exposed work in industrial
production (mainly metallurgy, machines and appliances), building and public works or services,
sectors characterized by occasional exposure to asbestos.  It is these types of exposure that will causethe 20,000 deaths expected to occur among men in France between now and the year 2020.
Question 23:  Have cases of death clearly attribut able to occasional, but high exposure ("of the
exposure peak" type) been documented?
95. All the studies based on the individual examination of mesothelioma cases, documented by a
detailed study of the patient's work history, have shown that since the 1970s the great majority of
cases have occurred among workers who have never had any type of exposure other than occasional
exposure with pollution peaks.  The studies are mainly of two kinds:
• Studies relating to cases of acknowledgement of occupational illnesses, which always
involve an in-depth examination of the circumstances of exposure, in particular,
because of the financial consequences of acknowledgement (payments of benefits andpensions).  Thus the above-mentioned study
49 by the Quebec Occupational Health
and Safety Commission (CSST) shows that during recent times the cases of
mesothelioma acknowledged as being an occupational illness generally correspond to
short-term exposure and most frequently involve servicing and maintenance workers.
• Epidemiological studies of the "case-control" type, in which each case of
mesothelioma considered forms the subject of  an in-depth examination of the victim's
entire working life by industrial health experts.  Because of their high scientific
quality, studies of this kind are particularly suitable for assessing the circumstances of
exposure.  The recently published study by Iwatsubo et al.,50 concerning cases that
occurred between 1987 and 1993 in France, is of this type.  It, too, shows that almost
all the mesotheliomas reported in France were observed in patients who had been
subjected to only occasional exposure with pollution peaks. The previously
                                                     
47 Far fewer workers (about 1,500 in France) are employed in de-flocking and demolition than in
"secondary" user occupations (several hundred thousand people exposed daily).

mentioned study by Siemiatycki51 in Montreal, which is of the same case-control
type, yielded similar results.
Question 24:  The Comparative Table  of the Characteristics of the Fibres Studied by the CSTEE
(Section III.B.6) submitted by the European Communities, seems to indicate that the diameter
of PVA, para-aramid and cellulose fibres could be greater than their length.  Could theEuropean Communities clarify these figures.
96. The fibres which must be taken into account in making a metrological assessment of a
working environment have been defined by WHO
52 in accordance with the following dimensional
parameters:  (i) more than 5 microns in length;  (ii) less than 3 microns in diameter;  (iii) ratio of
length to diameter greater than 3 microns.  The table in question is intended to show that the polyvinyl
alcohol, cellulose and para-aramid fibres generally used in France for replacing chrysotile asbestos allhave lengths distinctly greater than the 5 microns indicated by WHO;  in any event, all the fibres in
question have a length that is greater than the diameter.  The diameters of these fibres are greater than
10 microns.  This physically prevents them from penetrating into the pulmonary alveoli, which are
accessible only to fibres less than 3 microns in diameter.  Hence this characteristic of the substitute
fibres eliminates the risk of their penetrating deep in to the lungs.  It is important to note that, generally
speaking, unlike chrysotile fibres which have a diameter of between 0.1 and 1 micron and which
separate lengthways into even finer crystalline fibrils (0.020 microns), the synthetic fibres used as
substitutes, whether of organic or mineral origin, retain the diameter resulting from the manufacturing
process throughout the life cycle of the fibre, even when released into the air from a material
undergoing machining.
Question 25:  The European Communities indicate that the substitute products using fibres
shown to be harmless or less harmful include cellulose, PVA or aramid fibres.  Could the
European Communities give further details of the harmlessness or low toxicity of these
products?
97. Cellulose, polyvinyl alcohol and aramid fibres have been used for a very long time, since well
before asbestos was banned in France.  There has been nothing to give cause for concern, (in
particular, reports of cases of cancer among the workers exposed) which might have led to extensive
research, whereas asbestos has been the subject of numerous scientific studies because of the large
number of cases of disease found in workers over the last 70 years.  The CSTEE committee of
DG XXIV of the Commission of the European Communities and COC in the United Kingdom have
made in-depth assessments of the comparative risks of asbestos and the fibres used to replace it,particularly in asbestos cement.
98. On the basis of an analysis of the studies and reports supplied by the Health and Safety
Executive, COC
53 concluded:  (i) with regard to polyvinyl alcohol fibres, "these fibres will have no
potential for the induction of lung cancer or mesothelioma" (...).  The information on PVA suggests a
low carcinogenic hazard";  (ii) with regard to para-aramid fibres, "although there is some evidence ofadverse biological effects with para-aramids, there is no convincing evidence to suggest a
carcinogenic hazard (...).  The evidence suggests a lower carcinogenic risk than chrysotile";  with
regard to cellulose fibres, "a recent investigation with cellulose fibres had documented evidence of a
long biopersistence in the rat lung.  However, the COC agreed that this study was not relevant to
consideration of the question [... and] that it wa s unlikely [to] identify a carcinogenic response

Substitutes, Committee on the Carcinogenicity of Chemicals in Food, Consumer Products and the Environment

Page 28
attributable to cellulose fibres."  The COC concluded from its study that "the evidence presented to
the committee on fibre dimensions, studies in animal s including that of biopersistence in the lung,
indicate that the carcinogenic risk posed by PVA fibres, para-aramid fibres or cellulose fibres is likely
to be less than that posed by chrysotile".  These conclusions are shared by CSTEE of DG XXIV54
which found that "there is sufficient evidence that all forms of asbestos, including chrysotile, are
carcinogenic in humans.  There is no evidence of the occurrence of cancer induced by fibres in
humans with respect to any of the three substitute products [investigated]".  CSTEE also notes that
"pulmonary fibrosis is a well-known consequence of exposure to chrysotile [whereas], so far, no case
has been reported among workers exposed to any of the three substitute products".
Question 26:  The European Communities mainta in that the Agreement on Technical Barriers
to Trade does not cover general prohibitions on the use of the product.  In the present case,
Decree No. 96-1133 provides for the possibility of exceptions to the ban.  Do theEuropean Communities consider that the Agreeme nt on Technical Barriers to Trade is also
inapplicable to these exceptions and to  the provisions relating to them?
99. The French Decree provides that in certain circumstances a limited number of products may
contain asbestos (see Art. 2(I) of the Decree).  The European Communities consider that, like thegeneral ban, the exceptions to the general ban do not constitute "technical regulations" in the meaning
of the TBT Agreement.  The reason is that the definition of a "technical regulation" requires that the
document concerned must "lay down product characteristics or their related processes and production
methods." Article 2(I) of the French Decree does not lay down any particular characteristics.  In
particular, it does not stipulate any performance or design characteristics that such products mustmeet.  All it does is to permit, provisionally and und er justified conditions, the use of asbestos (in a
general sense, not as a specific characteristic), in the absence of a substance that ensures equivalent
performance.  The exceptions in the French Decree deal with or are based on the specific
characteristics of asbestos, not of the products that are allowed provisionally to contain it.
100. The provisions of the French Decree, which lay down the procedures for establishing which
products may be allowed under an exception, also do not qualify as a technical regulation.  Contrary
to what Brazil argues, the inclusion of the term "applicable administrative provisions" in the definition
of a "technical regulation" does not give independent meaning and existence to the term "applicable
administrative provisions", but simply clarifies that the definition includes such legislative provisions.
Question 27:  The European Communities state that "many substitute products are not fibrous
in texture".  Could the European Communities indicate, within the context of their analysis of
"likeness" within the meaning of Article III:4, which parts of their argument relate to substituteproducts containing fibres and which to non-fibrous substitutes?
101. See paragraphs 102 and 103 below.
Question 28:  The European Communities indi cate that "Canada mentions only fibrous
substitute products (cellulose, para-aramid, PVA), making no reference at all to non-fibrousproducts."  In the opinion of the European Communities, is it appropriate to take into account
non-fibrous substitute products for the purpose of examining, in the pres ent case, the likeness of
the products under Article III:4 of GATT 1994 or Article 2.1 of the Agreement on Technical
Barriers to Trade?
102. The European Communities have explained in their submissions (and in their reply to wr itten
question No. 29 of the Panel) that it is essentially the morphology of the chrysotile fibres (in terms of

length and diameter/thickness) that determines their carcinogenic effects.  As the mode of action of
the fibres is through inhalation, the fibrous nature of the chrysotile asbestos is essential.  In legal
terms, the fibrous nature relates directly to the product’s properties, nature and characteristics and,
probably, end-use.  That probably explains why Canada has claimed "likeness" only with regard to
substitute fibrous products.  It is, therefore, probably not necessary for the Panel to determine whethernon-fibrous substitute products are "like" products to chrysotile or chrysotile containing products.
103. The arguments in the European Communities' first written submission relate primarily to the
fibrous nature of chrysotile and chrysotile-containing products, on the one hand, and the fibrous
substitute products, on the other.  The European Communities have demonstrated that the fibrous
substitute products are not like products to chrysotile or chrysotile-containing products on the basis of
the four criteria normally used by Panels.
55  It follows that, a fortiori , non-fibrous substitute products
are also not "like" products, an additional reason being the even more marked difference in thephysical characteristics or nature of the products concerned.
3. Questions by the Panel to both parties
Question 29:  Does the term "chrysotile" cover a product of uniform quality (in particular, in
terms of the length and quality of the fibres) or should it be assumed that there are different
qualities of chrysotile and, therefore, different levels of risk?
(i) Reply by Canada
104. In strictly technical and commercial terms, there are various groups of chrysotile fibres which
are classified according to their length.  The method developed by the Association of Asbestos Mines
of Quebec has been adopted by the majority of producer countries for the classification of chrysotileand lists the groups of fibres from the longest fibres  (Group 1) to the shortest (Group 7).  The length
of fibre is normally measured in millimetres (10
-3 metres).  This classification is used to determine the
strength of the fibre used;  the longest groups of fibres are used for the manufacture of chrysotile
cement products, while the shortest fibre groups are used for the manufacture of friction products,
mastics and roof coatings.
105. This technical and commercial classification, howev er, has nothing to do with the level of risk
to health, which should be evaluated on the basis of the criteria of durability (biopersistence), dose
and dimension.  The pathogenicity of the fibres is examined on the basis of their dimension:  for a
natural or synthetic fibre to be potentially harmful, it must have a length greater than five microns, a
diameter less than three microns and a length to diameter ratio over 3:1 (a micron is equal to
10-6 metres).
(ii) Reply by the European Communities
106. Chrysotile, a natural mineral of the asbestos group, is a magnesium silicate of crystalline
structure with the empirical formula "Mg 3 (Si 2 O5) (OH) 4".  In chrysotile, as in all silicates, chemical
elements other than magnesium may be present in low concentrations and variable proportions.  Thus
the chemical analysis of different samples of chrysotile may yield results which vary over the
following ranges:
                                                     
55 That is the product’s properties, nature and quality, tariff classification, the product’s end-uses given
market and consumers’ tastes and habits.WT/DS135/R/Add.1

Calcium oxide (CaO) 0 to 2%
Sodium oxide (Na 2O) 0 to 1%

107. Finally, at the same geological site, the purity of a vein of chrysotile in the process of being
mined may vary from one point to another.  It may also differ between sites.  A deposit of chrysotile
asbestos (like any natural ore) is never perfectly pure and may contain various types of impurities
which will still be present, in whole or in part, in the asbestos-containing end-products.  This applies,
in particular, to quartz (silica) and other non-fibrous or fibrous silicates, such as amphibole asbestos.
108. Incidentally, chemical composition alone is not sufficient to identify a mineral;  the physical
structure is equally important.  Thus, minerals such as lizardite and antigorite have exactly the same
chemical composition as chrysolite but are not fibrous.
109. Under the heading "chrysotile" it is possible to distinguish between the forms that contain
impurities (that is, a small proportion of tremolite, an asbestos of the amphibole type) and those thatcontain no impurities or only very small amounts.  Despite attempts to show that only the traces of
tremolite present in Canadian chrysotile are responsible for the numerous mesotheliomas among
workers exposed to it, no difference in toxicity between these two forms of chrysotile has ever been
proved.  This theory of chrysotile being "inoffens ive" with respect to mesothelioma has, moreover,
been rejected by the scientific community
56 as noted in the written submission of the
European Communities.57  As far as we know, there is only one epidemiological study concerning
Zimbabwe's chrysotile which is reputed not to contain amphiboles:  it shows a net excess of
mesothelioma among the workers in chrysotile mines and mills.58  Thus, from the standpoint of the
composition of chrysotile, there is no reason to believe that the toxicity of the pure forms with respect
to mesothelioma would be any different from that of the forms that contain impurities.
110. It appears to be clearly established that it is essentially the morphology of the fibres, rather
than their geological origin, that determines thei r carcinogenicity with respect to the lungs.  These
conclusions stem from observation of the very high risks to which groups of textile asbestos workers
handling fine fibre chrysotile are exposed.  (It should be noted that the asbestos used by some of these
groups comes from Canada.)  For their part, chrysotile "mine and mill" workers exposed to thickerfibres present clear but much lower risks.
59
111. As Landrigan60 notes, the risks of cancer of the lung can vary by a factor of 50 between a
group of chrysotile miners and a group of industrial workers handling chrysotile asbestos from the
same mines.  Reference may also be made to the INSERM Report61 which compares the risks of

cancer of the lung according to the industry using th e chrysotile.  The very considerable differences in
risks observed are mainly attributable to differences in the morphology of the fibres, which are
subjected to different forms of physical processing depending on the end-use:  generally short and
thick when mined, they may undergo changes in morphology and be made finer to adapt them better
to particular uses.
Question 30:  What are the output and import and export volumes of substitutes for chrysotile
asbestos products, particularly asbestos cement, in France and Canada respectively?
(i) Reply by Canada
112. Without wishing to offer a full review of all th e substitute products individually, the following
is an indicative summary of the value of the pr oducts used as substitutes for chrysotile asbestos
products (1997 data):
PRODUCT PRODUCTION IMPORTS EXPORTS
Concrete pipe $212,055M $0,426M $22,846M
Forged pipe and steel tubing $2381,270M $1174,0M $727,282M
Plastic pipe (PVC) $794,000M $305,000M $271,000M

113. In France, more than 90 per cent of imported chrysotile asbestos fibre was used for making
asbestos-cement products.  Since asbestos was banned, the market in asbestos cement products and
materials has shifted towards:  (i) materials and technologies which have existed for a very long time
(for example, PVC and ductile iron for making pipes, aluminium for roofing);  (ii) fibre substitutes forasbestos:  mainly cellulose fibres and, to a lesser extent, polyvinyl alcohol and polypropylene fibres.
114. The first submission of the European Communities provides some statistical data on cellulose
and polyvinyl alcohol fibres.  Cellulose fibres are mainly intended for the textile and paper (pulp)
industries.  Each year, the fibro-cement industry uses less than one per cent of the total volume of
cellulose fibres consumed in the various industrial sectors.  In 1998, France produced2,660,000 tonnes of cellulose fibres and imported 2,030,000 tonnes (including 660,000 tonnes from
countries of the European Union and 740,000 tonn es from North America, of which 380,000 tonnes
from Canada).  It should be noted that imports of cellulose fibre from Canada increased by
14,000 tonnes between 1996 and 1998.
115. Polyvinyl alcohol fibres, which are mainly used in the textile and packaging industries, are
made by only two factories in the world, one in China and the other in Japan.  In 1998, France
recorded a trade deficit of 700 tonnes or 115 m illion francs.  In 1998, deliveries from French
manufacturing units amounted to 4,200 tonnes and impor ts to 11,400 tonnes.  As far as other products
are concerned (the remaining ten per cent of chrysotile asbestos fibres consumed), the most popular
substitute has been man-made mineral fibres of the glass or rock fibre type (the great majority ofapplications), with very limited use being made of para-aramid and ceramic fibres (these two productsWT/DS135/R/Add.1
Page 32
are very expensive as compared with asbestos fibres).  With regard to para-aramid fibres, in 1998,
France recorded a trade deficit of 400 tonnes or 26 million francs.  Man-made mineral wools and
fibres are mainly produced in France and principally intended for insulating buildings.  It should be
noted that less than one per cent of the output of these man-made mineral wools and fibres is now
being used in products previously manufactured with asbestos.
Question 31:  Are there statistical data available  which indicate what are the positive effects of
controlled use, the use of encapsulated products and the banning of chrysotile asbestos,
respectively, as regards reducing the number of mesotheliomas and cancers of the lung?
(i) Reply by Canada
116. The sources of asbestos-related pathologies have been identified as utilization of amphibole
varieties in friable products such as flocking or cases of exposure to high quantities of chrysotile.
Controlled use, a practice that was gradually intr oduced in the 1970s, has eliminated these dangerous
sources.  However, since there is a latency period of some decades between exposure to asbestos and
the appearance of disease, pathologies related to uncontrolled exposure occurring up to the 1970s will
continue to appear for a few decades yet, even if the sources of that exposure have now disappeared.Furthermore, as long as the competent authorities do not ensure appropriate and systematic
management of the flockings installed during the years of uncontrolled use, the associated problems
will not be completely eliminated.
117. There are few statistics on the prohibition of flockings and the exclusive use of chrysotile at
low levels of exposure.  Data collected and compiled by the Asbestos International Association (AIA)in 1995 cover 28 countries with some 25,000 workers employed.
62  In these countries, because of the
introduction of controlled-use procedures and measures, the A.I.A. surveys show that 97.3 per cent of
workers are exposed to less than 1.0 f/ml.  These exposure levels satisfy the recommendations on
worker protection made by the Group of Experts which met under the auspices of the WHO in
Oxford, England, in April 1989.  The findings of a similar survey conducted in 1997 will be availablein the summer of 1999.
118. It should also be made clear that there is little data for assessing the positive effects of
controlled and exclusive use of chrysotile asbestos, and that the reference period does not begin until
the late 1970s when the current workplace controls were implemented (plants in a few countries for
the manufacture of asbestos cement and friction materials).
119. Other data have also been published on groups of workers in chrysotile asbestos mines in
Quebec, which feature both a sufficiently high number of workers and a sufficiently long observationperiod to measure the effects of asbestos exposure.  The study covers cohorts formed in 1966 and
monitored since then
63,  including more than 11,000 workers born between 1891 and 1920.  The most
recent update, published in 1997, reports data until 1992.  The findings for workers in this group who
were exposed to chrysotile concentrations of up to 22f/ml for 40 years led the authors to conclude
"from the point of view of mortality that exposur e in this industry to less than 300 mpcf. years
[i.e. equal to about 22f/ml over 40 years] has been essentially innocuous."

120. To the best of our knowledge, the only published study that enables the effectiveness of
controlled use to be measured is that issued in 1996 by the Health and Safety Executive64 in the
United Kingdom concerning the risks of cancer incurred by asbestos workers after 1969, when the
"safe" use of asbestos was adopted by the United  Kingdom.  This study shows that, despite strictly
"controlled" use (since the study relates exclusively to workers making asbestos-based products),
there is a significant net excess of cancers among those who worked only under the "controlled" use
regime.  It follows from this finding that "controlled" use does not make it possible to prevent deaths
from cancer, even in specific industrial manufacturing sectors with a workforce which is relatively
small and a priori easy to train and supervise.
121. For at least 40 years, the manufacture of asbestos cement has involved "encapsulating"
asbestos in cement.  This encapsulation does not guarantee the harmlessness of asbestos cementduring use:  in practice, when asbestos cement is used, in an occupational, para-occupational or
domestic environment, it is generally sanded, crushed or sawn and releases carcinogenic fibres in the
form of dust.  The occurrence of mesotheliomas among workers exposed to asbestos fibres which, in
the manufacturing stage, were encapsulated in cement clearly shows that this process offers absolutely
no protection against the carcinogenic effects of chrysotile fibres released when products andmaterials containing "encapsulated" asbestos are worked.  This is perfectly understandable
considering the very high levels of exposure measured under these conditions.  It is possible to
encounter concentrations several tens, even several hundreds of times higher than the national
statutory limits
65 and the internationally recommended levels.66
122. The number of asbestos-related illnesses in a country is very strongly correlated with the
amount of asbestos imported into that country. The most effective way of reducing, in the future, the
number of asbestos-related illnesses is therefore to reduce asbestos imports.  A ban with exceptions is
the most effective means of achieving that result.  France has demonstrated this, since imports fell
very rapidly after the implementation of the ban (an estimated 1,200 tonnes in 1997, 200 tonnes in
1998, and a projected 55 tonnes in 1999 as against 35,000 tonnes in 1995).  Thus, France could notafford to wait another 30 years in order to verify whether tighter controls on so-called "safe" use
would make it possible to achieve the same results.
Question 32:  With regard to substitute products is there a difference in potential or proven risk
between fibrous and non-fibrous products?
(i) Reply by Canada
123. The replacement of fibre products with products containing no fibre might imply that the
manufacture and use of the latter are risk free.  This is not the case, at least for certain non-fibrous
products being proposed as substitutes for chrysotile asbestos products.  Only a comparative, case-by-
case evaluation can yield relevant information.  For example, let us take the alternative of PVC pipes.
It should be realized that manufacture of the vinyl chloride monomer (a proven carcinogen which islater polymerized in PVC) involves the use of chlo rine, an element which is later incorporated in an
organic molecule.  It has been well established that the synthesis of organo-chlorines is a significant
source of dioxins, substances whose medium to long-term effects are very harmful, and regarding

(approximately 220ng/year).
124. The fact that the production of ductile iron also poses health risks recognized by the IARC as
Group I is something which should not be concealed, since it entails greater energy consumption
leading to the emission of carcinogens such as po lynuclear aromatic hydrocarbons (PAH), etc..  These
two examples clearly show that there are virtuall y no products or technologies that offer zero risk:
one must learn to control and manage the risks with in the framework of a policy of controlled and
disciplined use.  In any case, only a case-by-case analysis can answer the question asked.
(ii) Reply by the European Communities
125. The carcinogenic effect of asbestos is linked with its inhalation.  In fact, not only does
asbestos have a length to diameter ratio that enables it to penetrate into the pulmonary alveoli67 but, in
addition, asbestos fibres are all capable of separating lengthways into even finer crystalline fibres,
including inside the bronchial tree, which helps them to penetrate into the deepest recesses of the
lungs.  Many of the products used to replace asbestos cement rely on alternative technologies which
do not use fibres.  Accordingly, these products, which cannot be inhaled, do not carry any threat of
carcinogenicity.  Non-fibrous products such as ductile iron and PVC have never been suspected ofbeing carcinogenic and no case of cancer among the workers exposed has been recorded, although the
products have been used for a very long time for a wide variety of purposes.  The dust released when
they are machined (against which protection should in any case be provided) is considered to be
without specific toxicity for the human organism (ductile iron or plastic dust).
126. In assessing the carcinogenicity of fibrou s products, WHO takes into consideration, in
particular, the ratio of length to diameter
68 which makes it possible or impossible for the fibres to
penetrate into the pulmonary alveoli.  Fibres are used to replace asbestos in asbestos cement.  With the
exception of man-made mineral fibres, none of the fibres used to replace chrysotile has a length to
diameter ratio that enables them to penetrate into the lungs.  In fact, polyvinyl alcohol and para-
aramid fibres are 2 to 8 mm. (i.e. 2,000 to 8,000 microns) in length and 10 to 16 microns in diameter.Only cellulose fibres, which are 12 to 40 microns in diameter, can give rise to finer particles which
are said to irritate the respiratory pathways, but which are never carcinogenic.  None of the fibres
sometimes used to replace chrysotile asbestos (glass or rock man-made mineral fibres, organic fibres
such as aramid fibres, plant fibres such as cellulose) are capable of separating lengthways:  fibres
extracted from the material retain their original diameter, which is almost always greater than the
basic diameter of asbestos fibres.
127. Thus, scientifically, a consensus exists in favour of the following classification based on risk:
(i) asbestos, of both the amphibole and chrysotile varieties, is a proven human carcinogen
69;  (ii) some
fibrous substitute products, such as ceramic fibres, are suspected70 of being carcinogenic:  their
carcinogenicity has been revealed by animal studies, but there is no evidence of their being
carcinogenic in humans;  (iii) the other fibrous products used instead of asbestos (PVA, cellulose,
para-aramids, glass and rock fibres) are not human carcinogens.71  There have been no studies
designed to determine whether or not they are carcinogenic in animals;  (iv) the non-fibrous products
have never been suspected of being carcinogenic.  It should be noted that the use of the substitute

Question 33:  Is the concept of necessity in Article XX:(b) of GATT the same as that in
Article 2.2 of the Agreement on Technical Barriers to Trade?
(i) Reply by Canada
128. With regard to 'necessity', the text of Article 2.2 of the TBT Agreement is not identical to the
text of Article XX:(b) of GATT 1994.  Article XX:(b) uses the phrase, "necessary to protect […]".
Article 2.2 of the TBT Agreement evokes the concept of necessity in a more specific context:  "not
more trade-restrictive than necessary to fulfil a legitimate objective, taking account of the risks non-fulfilment would create".  Article 2.2 in particular prescribes that account be taken of available
scientific and technical information and the intended end uses of the products.
129. Despite the differences in textual formulation, the case law that has developed around
analysis of Article XX:(b) can be helpful in dete rmining the substance of the concept of necessity in
Article 2.2.  Conversely, the avenues for evaluating the 'necessity' of the measure contained in 2.2(i.e. use of scientific information and consideration of end uses) may be relevant to analysis of
necessity under Article XX:(b).
(ii) Reply by the European Communities
130. All the Panel reports that have examined the concept of necessity in the context of
Article XX:(b) of GATT have concluded that it was not the necessity of the policy goal pursued by
the measures at stake that was to be examined, but whether or not it was necessary to subject the
imported products to the legal regime of the contested measure.  In all cases a measure inconsistent
with another provision of GATT was found to be not "necessary" if an alternative measure which the
defending Member could reasonably be expected to employ and which was not inconsistent (or lessinconsistent) with other GATT provisions was available to it.
72  The same should apply as regards the
concept of necessity in the context of Article 2.2 of  the TBT Agreement.  This results clearly from the
ordinary meaning of the terms of Article 2.2 in their context, which state that:  "For this purpose,
technical regulations shall not be more trade-restrictive than necessary to fulfil a legitimate objective,
taking account of the risks non-fulfilment would create".  The sixth preambular paragraph to the
TBT Agreement clarifies that Members have the au tonomous right to determine the level of human
health protection they consider appropriate in their territory.  The necessity test, therefore, inArticle 2.2 may only be applied in order to examine whether the technical regulations have been
prepared, adopted or applied "with a view to or with the effect of creating unnecessary obstacles to
international trade".  An obstacle to trade will be found to be unnecessary, if another measure
consistent (or less inconsistent) with GATT is reasonably available to the defending Member, to
enable it to achieve the level of health protection which it has determined.
131. The fact that, in substance, the necessity test should be applied in the same way in both
provisions does not, however, have the same procedural implications as regards, for instance, the
burden of proof.  Unlike Article XX:(b) of GATT 1994, where initially the burden is on the Member
claiming its application to prove it, in the context of Article 2.2 of the TBT Agreement, the burden is
initially on the plaintiff Member to establish that there has been a violation.  Indeed, the plaintiff
                                                     
72 See United States - Section 337 of the Tariff Act 1930 , BISD 36S/386, paragraph 5.26 (adopted on

Member must first demonstrate the availability of an alternative consistent or less inconsistent
measure which can achieve the level of health protection determined by the defending Member.73  The
European Communities have already explained that so-called "controlled use" is not "an alternative
measure" because, inter alia , it does not provide the same level of protection as the French Decree.
The European Communities would, moreover, recall that, as is clear from the factual part of their twowritten submissions, it is "in the real world" not feasible to make sure that controlled use is applied in
all circumstances where people work with asbestos in such a way as to achieve the level of sanitary
protection determined by France.
Question 34:  Is the notion of "like product" within the meaning of Article III:4 of GATT 1994
identical with that of "like product" within th e meaning of Article III:2, first sentence of GATT
1994?
(i) Reply by Canada
132. The case law of GATT and the WTO indicates that the concept of "like product" in
Article III:2 is to be construed narrowly. However this narrow interpretation does not apply to
Article III:4 where the concept of likeness must be construed more broadly, given the purpose andcontext of Article III:4.  Consequently, Article III:4 encompasses a more extended "range of like
products" than does Article III:2, first sentence.
133. The report of the Appellate Body in Japan – Taxes on Alcoholic Beverages , in its discussion
of Article III:2 commented precisely on the relative character of likeness under various articles and
under various agreements.
"No one approach to exercising judgement will be appropriate for all cases.  The criteria in border tax
adjustments should be examined, but there can be no one precise and absolute definition of what is
"like".  The concept of "likeness" is a relative one that evokes the image of an accordion.  The
accordion of "likeness" stretches and squeezes in different places as different provisions of the WTOAgreement are applied.  The width of the accordion in any one of those places must be determined by
the particular provision in which the term "like" is encountered as well as by the context and
circumstances that prevail in any given case to which that provision may apply."74
134. In the same report, the Appellate Body commented on the helpfulness of a "case-by-case"
examination and pointed out the narrowness of the "accordion of likeness" in the first sentence of
Article III:2
"This approach should be helpful in identifying on a case-by-case basis the range of "like products"
that fall within the narrow limits of Article III:2, first sentence in GATT 1994.  Yet this approach will
be most helpful if decision-makers keep ever in mind how narrow the range of "like products" in
Article III:2, first sentence, is meant to be, as oppos ed to the range of "like" products contemplated in
some other provisions of GATT 1994 and other multilateral trade agreements of the WTO
Agreement."75
135. Using the analogy of the accordion of likeness, the Panel in Japan – Taxes on Alcoholic
Beverages pointed out that the same interpretation of the term "like product" in Article III:2 and
Article III:4 would give a different scope to two pa ragraphs in the same Article.  Two paragraphs of
the same Article designed to protect the conditions of competition for products imported into the
territory of a WTO Member should not have a different scope.  Since the terms "directly competitive"
                                                     
73 See on this point, by analogy, the Appellate Body Report in Japan - Measures Affecting Agricultural
Products , AB-1998-8, para. 126.

or "directly substitutable" add to the term "like product" in defining the scope of Article III:2,
interpreting "like product" in III:4 in the same way as in III:2 would give a narrower overall scope to
Article III:4 than to Article III:2.  In Japan – Taxes on Alcoholic Beverages , the Panel wrote:
"6.20 The Panel noted that the term "like products" appears in various GATT provisions.  The Panel
further noted that it did not necessarily follow that the term had to be interpreted in a uniform way.  Inthis respect, the Panel noted the discrepancy between Article III:2, on the one hand, and Article III:4 onthe other:  while the former referred to Article III:1 and to like, as well as to directly competitive or
substitutable products (see also Article XIX of GATT), the latter referred only to like products.  If the
coverage
76 of Article III:2 is identical to that of Article III:4, a different interpretation of the term "like
product" would be called for in the two paragraphs."
136. What emerges from this Panel report is that the overall scope of paragraphs 2 and 4 of
Article III should be identical.  The Panel continues in paragraph 6.20:
"Otherwise, if the term "like product" were to be interpreted in an identical way in both instances, the
scope of the two paragraphs would be different.  This is precisely why, in the Panel's view, its
conclusions reached in this dispute are relevant only  for the interpretation of the term "like products" as
it appears in Article III:2."
137. It is therefore clear that the analysis of the term "like product" was valid only for III:2,
because the Panel did not want to give a different overall scope to the two paragraphs.  The concept of
"likeness" must therefore have a broader scope under Article III:4 than under III:2.  To maintain the
same scope in the two paragraphs, the accordion of "likeness" must be tightly squeezed in Article III:2
and stretched in Article III:4.  In Japan – Taxes on Alcoholic Beverages , the Appellate Body supports
the Panel's analysis and rejects the appellants' inte rpretation that the scope of Article III:2 (first and
second sentences) and of Article III:4 is not identical:
"We note the argument on appeal but the Panel suggested in paragraph 6.20 of the Panel report that the
product coverage of Article III:2 is not identical to the coverage of III:4.  That is not what the Panel
said."77
138. This interpretation of Canada's is consistent with doctrine on the subject.  For example,
Edmund McGovern observed:
"[…] the Appellate Body in the 1996 Japanese Alcohol case doubted whether [similar products] has the
same meaning even among the various paragraphs of Article III.  In particular, the narrow
interpretation appropriate in the first sentence of paragraph 2 (concerning internal taxation) does notnecessarily apply in the context of paragraph 4 (concerning internal regulations), and it is possible that"like products" in paragraph 4 might even have the same scope as "directly competitive andsubstitutable products" in paragraph 2. […]  Consequently, the point has to be discussed separately
with regard to each provision."
 78
139. Canada therefore maintains that the test of lik eness in Article III:4 is different from and
broader than that developed in Article III:2.
                                                     
76 Canada notes that, in using the term "coverage", the Panel wondered whether Article III:4 governed
the treatment of both the categories of products mentio ned in III:2, namely both "like" products and "directly
competitive or directly substitutable" products.

(ii) Reply by the European Communities
140. The European Communities consider that for the purpose of the present dispute the reply to
this question is of theoretical relevance only.  Canada does not claim a violation of Article III.2 of
GATT and it is clear from the submissions of the European Communities that only paragraph 4 ofArticle III of GATT might be of relevance in this case.  The European Commun ities have
demonstrated, however, that the French Decree does not discriminate either de jure  or de facto
between national and imported products.  It has been consistently held by Panels and the Appellate
Body that the concept of "like product" does not necessarily have the same meaning in all GATT
provisions in which it occurs and that its meaning "must be determined by the particular provision in
which the term "like" is encountered as well as by the context and the circumstances that prevail in
any given case to which that provision may apply."
79  The European Communities have explained in
their submissions that asbestos and asbestos-c ontaining products have very different physical
characteristics from products that do not contain asbestos and, therefore, cannot be considered "like
products."  Article III:4 does not cover "directly competitive or substitutable" products and, according
to the Appellate Body, such an omission must have some meaning.
Question 35:  What is the relationship betw een GATT 1994 and the Agreement on Technical
Barriers to Trade?  Does the nature of this relationship have any effect on the order in which a
panel should examine a measure alleged to constitute a violation of both GATT 1994 and the
Agreement on Technical Barriers to Trade?  Does  this relationship have any particular bearing
on the present dispute?
(i) Reply by Canada
141. The nature of the relation between the different agreements in Annex 1A to the Agreement
Establishing the World Trade Organization can be determined on the basis of the wording of the
General Interpretative Note to Annex 1A (Annex 1A).  This Interpretative Note was introduced inorder to reflect the relation between GATT and the 12 other Agreements constituting Annex 1A.  This
Note is directly modelled on the customary rule of interpretation of international public law whereby,
in the event of conflict, specific provisions prevail over more general rules.  The Note recognizes that
the 12 Agreements are, relative to GATT, provisions concerned with the detailed preparation and
application of the more general provisions of GATT.  These Agreements constitute the most recent
and most specific expression of the WTO Members as to what the interpretation and application of
these disciplines should be.
142. In the case of the Agreement on Technical Barriers to Trade, this is confirmed by the wording
of its Preamble, which states, among other things:  "Desiring to further the objectives of GATT
1994".
80  In this sense, then, the TBT Agreement is the most recent and the most specific expression
of the WTO Members as to the necessary interpretation and application of the general disciplines of
GATT (e.g. the obligations of Article I, III, X and XI in view of the exceptions provided for inArticle XX) in the context of technical regulations and standards.  The more specific character of the
TBT Agreement does not have the effect of setting aside the more general applicable disciplines of
GATT, and hence the two Agreements apply simultaneously and must be examined separately.  This
rule was clearly recognized by the Appellate Body in the Bananas III  case where it stated that:

"Although Article X:3(a) of GATT 1994 and Article 1.3 of the Licensing Agreement both apply, the
Panel, in our view, should have applied the Licensing Agreement first, since this Agreement dealsspecifically, and in detail, with the administration of import licensing procedures".
143. The same idea was revisited by the Panel in the Indonesian Automobiles  case, when it was
dealing with the issue of simultaneous application of the Agreement on Trade-Related Investment
Measures and Article III of GATT (see the report, paragraph 14.62).  With regard to the order in
which the Agreements should be considered by the Panel, since Article 2 of the TBT Agreement deals
in a more specific and detailed fashion with the preparation, adoption and application of technical
regulations and standards, giving due regard to what WTO Members consider to be an acceptablebalance between the various interests protected by the general provisions of GATT 1999, it seems to
us that the TBT Agreement must be examined first.   This position is in keeping with the approach
adopted by the Appellate Body in the Bananas III
81 case and by the Panel in the Indonesian
Automobiles  case.82 Therefore the TBT Agreement should be examined first.
(ii) Reply by the European Communities
144. GATT and the TBT Agreement are two legally distinct Agreements.  The General
Interpretative Note to Annex 1A to the WTO Ag reement clarifies that, in the event of conflict
between the two, the provisions of the TBT shall prevail to the extent of the conflict.  The object and
purpose of the TBT Agreement, like its predecessor Agreement, is "to further the objectives of GATT1994" (second preambular paragraph) in the areas of international standards and conformity
assessment systems so as to ensure that technical regulations and standards do not create unnecessary
obstacles to international trade (third to fifth preambular paragraphs).  The European Communities
consider that the legal relationship of the two agreements as explained above does not dictate any
particular order in which the Panel should examine the claims and arguments of the parties in thisdispute.  The two options of examining first GATT and then the TBT Agreement or vice versa are
both theoretically available.
145. The European Communities note, however, that several important concepts (such as the
concept of like products, the principle of non-discrimination or the concept of necessity) are found in
both Agreements, but there is very little case law and practice of the Members under the TBT
Agreement on which the Panel may draw.  It may therefore be more prudent, from the interpretative
point of view, to proceed first with an analysis under GATT, especially when the two parties disagree
on the applicability of one of the two agreements, in this instance the TBT Agreement.  This approach
is, in any case, not unusual, as is shown by the US Gasoline  Panel and Appellate Body reports.  The
choice of the order by which the claims of the parties under these two Agreements will be examined
does not appear to have any particular or significan t implication for this dispute, other than that the
Panel should ensure consistent interpretation of the provisions of the two Agreements.  As regards theseparate issue of allocation of the burden of proof, see the European Communities’ reply to Canada's
written question No. 8.

146. No, the exceptions provided for in Article XX of GATT are not intended to apply to
violations of the provisions of the TBT Agreemen t.  Article XX is not applicable outside GATT 1994
unless there is a specific stipulation to the contrary, as in the TRIMs Agreement.  The text of the TBTAgreement makes no reference to Article XX of GATT.
(ii) Reply by the European Communities
147. Yes, the European Communities consider that the basis of the exceptions in Article XX are
applicable under the TBT Agreement.  This means that the substantive grounds on which an exception
can be based under Article XX(b) of GATT 1994 ar e also available under the TBT Agreement.  This
derives from a systematic interpretation of the TBT Agreement and GATT, in particular the sixthpreambular paragraph of the TBT Agreement, and th e history of the preparatory work.  The European
Communities consider that the availability under the TBT Agreement of the reasons behind the
exceptions in GATT Article XX(b) does not appear to have any particular or significant implication
for this dispute, other than that the Panel should ensure consistent interpretation of the provisions of
the two Agreements.  As regards the separate issu e of allocation of the burden of proof, see the
European Communities' reply to Canada's written question No. 8.
Question 37:  What are the factors that determ ine the "relevance" of an international standard
within the meaning of Article 2.4 of the Agreement on Technical Barriers to Trade?
(i) Reply by Canada
148. The "relevance" of an international standard is a question of fact which must be determined
on a case-by-case basis.
149. The ordinary meaning of the word "pertinent"  is given in Larousse as "approprié, qui se
rapporte exactement à ce dont il est question."  The English version of the TBT Agreement uses the
word "relevant", which is defined by the Concise Oxford Dictionary as:  "bearing on or pertaining to
the matter at hand."
150. In this case, the international standards cited by Canada are relevant since they relate to the
same product, namely asbestos, and to the same regulatory purpose, namely protection of the health of
workers and individuals.  The international standards all deal with the use of chrysotile in a controlled
and safe manner.
151. The Panel must also be aware that the relevance of the international standards invoked by
Canada has never been challenged by the European Communities.  Rather, the
European Communities confine themselves to attempting to demonstrate that the international
standards cited by Canada are not "international standards" within the meaning of the TBT
Agreement.
(ii) Reply by the European Communities
152. The phrase in question reads: "[w]here technical regulations are required and relevant
international standards exist or their completi on is imminent (…)."  The ordinary meaning of
"relevant" is bearing on or pertaining to the matter at hand.
83  The context of this provision, however,
makes it clear that the substantive requirement to j udge the relevance of an international standard is
                                                     
83 The Oxford English Reference Dictionary, 1995.WT/DS135/R/Add.1
Page 41
that the latter should meet the requirements of the definition of "technical regulation" in Annex 1 to
the TBT Agreement (see Article 1.2 of the TBT Agreement).
153. In the present case, none of the international standards invoked by Canada define the
characteristics which asbestos or products containing asbestos must have.  They deal, for instance,
with the way in which asbestos and asbestos-contai ning products must be handled in the workplace
and the relationship between employers and employees.  They are, therefore, not "relevant" in the
meaning of Article. 2.4 of the TBT Agreement.  In any case, even if they were relevant (which they
are not) they would be completely ineffective and inappropriate to fulfil the legitimate objective of
France, which is to protect human health in its territory.
Question 38:  In the context of the Agreement on Technical Barriers to Trade, is a Member free
to determine, for the purpose of drafting and adopting a technical regulation, the level of
protection it considers appropriate?
(i) Reply by Canada
154. Yes, but in compliance with the obligations of the TBT Agreement.  For example, a Member's
freedom to adopt a regulation for the protection of human health, at the levels it considers appropriate,is mentioned in paragraph 6 of the preamble to  the TBT Agreement.  However, this freedom is
circumscribed.  First, it is subject to the requirement that the technical regulation does not constitute
either a means of arbitrary or unjustifiable discrimination between countries where the same
conditions prevail or a disguised restriction on international trade.  Second, it is subject to the
technical regulation being otherwise in accordan ce with the provisions of the TBT Agreement.
(ii) Reply by the European Communities
155. Yes.  Article 2.2 of the TBT Agreement provides that protection of human health and safety is
a legitimate objective.  The preamble to that agreement confirms that "no country should be prevented
from taking measures necessary to … protect human … life or health, at the levels it considersappropriate (…)".
Question 39:  Article 2.4 of the Agreement on  Technical Barriers to Trade envisages the
situation in which the relevant international standards or the relevant parts of them would be
"an ineffective or inappropriate means for the fulfilment of the legitimate objectives pursued,
for instance because of fundamental climatic or geographical factors or fundamental
technological problems".  What other types of situation would be liable to make the standards
or some of their parts "ineffective or inappr opriate" within the meaning of this article?
(i) Reply by Canada
156. Situations that might render international standards or certain parts of them ineffective or
inappropriate, other than those situations explici tly mentioned in Article 2.4, should be examined in
the light of the ordinary meaning of the terms in this article, taken in their context.  The text of
Article 2.4 states that they must be "fundamental" factors or problems.
157. For Article 2.4 not to be stripped of its meaning, it requires that, in order to set aside an
otherwise relevant international standard, the Member must provide real and tangible evidence of a
"fundamental" consideration and not a mere allegation that certain standards are not appropriate.WT/DS135/R/Add.1
Page 42
(ii) Reply by the European Communities
158. The most obvious examples are when the latest scientific evidence suggests that the scientific
basis of an international standard is inaccurate or obsolete, or when the level of protection that could
be achieved by the international standard is lower than that determined by a Member in its territory.In the present case, the relevant scientific evidence that became available, in particular in the late
1980s and early 1990s, indicates that:  (i) there is no doubt at all that chrysotile asbestos is a proven
carcinogen;  (ii) there is no safe exposure limit (threshold) for chrysotile asbestos and products
containing asbestos;  (iii) so-called "controlled use" is not applicable in all circumstances and for all
types of persons that may come in contact with  asbestos or asbestos-containing products and, in
addition, does not eliminate all the risks;  and (iv) there are substitute products that are safe, or safer
than chrysotile asbestos.
159. Under these circumstances it is clear that an international standard that would permit the use
of asbestos or asbestos-containing products or would set an exposure limit or would recommend
"controlled use" would be ineffective or inappropriate to achieve the level of health protection
determined by France.
4. Questions by Canada to the European Communities
Question 1:  The first written submission of the European Communities states that
"mesothelioma is a pleural cancer for which the on ly known cause is the inhalation of asbestos".
Are we to take this assertion to mean that the European Communities are unaware of the
scientific data identifying x-rays and erionite, inter alia , as causes of mesothelioma?
160. Erionite is indeed an indisputable cause of mesothelioma (as was made clear in the INSERM
Report:  see pages 125-126);  however, exposure to the fibres of erionite, a mineral of natural origin,
has to our knowledge been documented only in the Turkish region of Cappadocia.  For that reason, in
Section 4(a) of the first submission by the European Communities, a more complete form of words
was used:  "apart from exposure to asbestos, no other causal factor present in the industrializedcountries has been established or even seriously suspected".  As for the other factors mentioned by
Canada, such as x-rays, none has been positively confirmed up to now, even though presumptions
exist in the case of some;  none of them is classified in Group 1 of the International Agency for
Research on Cancer as a proven carcinogen with regard to mesothelioma.
Question 2:
(a) In paragraph 238 of their first writte n submission, the European Communities
conclude that the controlled use policy is inapplicable.  Was France applying a policy of
controlled use of asbestos at the time when  the workers referred to in the study by Y.
Iwatsubo were exposed?  If not, how can this policy be found to be inapplicable?
161. The study by Iwatsubo et al. concerns workers who developed mesothelioma in recent years
(1987-1993) and who have therefore been exposed to asbestos during a period dating back at least 20
or 30 years, when so-called controlled use was not applied.  However, the study in question (like
others cited in the European Communities' submission, which were carried out in different countries),
confirms that the vast majority of such cases of mesothelioma occurred in a wide variety of trades,
particularly in the construction sector, where workers are in most cases unaware of their sporadicexposure due to having to handle a wide range of materials that have frequently been in place over a
very long period of time without anyone knowing of their asbestos content.
162. The study by Iwatsubo et al., like similar studies, has the advantage of showing clearly that
"controlled use" procedures would have to be ap plied on so wide a scale (several hundred thousandWT/DS135/R/Add.1
Page 43
workers a day in France carry out isolated operations on materials containing asbestos) that they are in
practice largely unrealistic although every effort must be made to encourage such procedures given
the enormous quantities of asbestos that have been imported for decades and which remain in place.
Moreover, the prevailing unawareness that the materials concerned contain asbestos makes it even
more difficult to introduce such work procedures systematically;  it would mean in practice putting asupervisor behind every worker in the construction trade and numerous other sectors of activity which
use heavy equipment covered by the ISO 7337 Standard, and prohibiting any operation until checks
have been carried out on the presence of asbestos.  Specifically, that would mean having to send a
sample of the material on which a sometimes very brief operation is to be carried out (such as drilling
or sawing) to an approved laboratory and awaiting  the laboratory findings.  It is clear that the
procedures described above cannot be applied on such a broad scale, uniformly and continuously,
i.e. over a period of decades given the continued presence of asbestos.
Question 2:
(b) Could the European Communities specify the varieties of asbestos to which the persons
covered by the study by Y. Iwatsubo et al. were exposed?
163. The study by Iwatsubo et al.  does not distinguish between the varieties of asbestos to which
workers suffering from mesothelioma were exposed.  However, France has used chrysotile almost
exclusively:  the share of amphiboles in asbestos imports into France has not exceeded 3 per cent
since 1945, and France has never produced amphiboles domestically.  Amphiboles were used mainly
for specific purposes:  it is therefore highly likely that the great majority of workers with
mesothelioma covered by the study by Iwatsubo et coll.  were never exposed to any variety of asbestos
other than chrysotile.
Question 3:  The European Communities acknowl edge in Section 4(a) of their first written
submission that there is a difference between the toxicity of chrysotile and that of amphiboles.
Do the European Communities therefore ackno wledge that assessment of the risk from
exposure to chrysotile exclusively must be based solely on data concerning chrysotile exposure,
and not on data concerning exposure to amphiboles or mixtures of asbestos containing
amphiboles?
This question calls for two preliminary comments:
• The European Communities pointed out in their first written submission that, while it
is true that amphiboles appear to be a more important cause of mesothelioma than
chrysotile, that is not the case for lung cancer.  However, lung cancer has caused a
higher number of asbestos-related deaths than mesothelioma (many authors consider
that for every death from mesothelioma there is at least one or even possibly
two deaths from cancer of the lung due to asbestos).  It is therefore impossible to
accept the wording of the question by Canada which, once again, seems to be seekingto ignore this fact.
• Canada does not explain what is meant by "exposure to chrysotile exclusively" :  the
chrysotile produced by Canada is contaminated by tremolite (a variety of amphiboleasbestos with a very strong carcinogenic potential in respect of mesothelioma).  This
argument has also been widely used by the "defenders" of chrysotile to dispute thefact that the latter could cause mesothelioma (the reasoning being that the traces of
tremolite contained in Canadian chrysotile were solely responsible for the many cases
of mesothelioma observed among workers exposed to Canadian chrysotile asbestos).
This theory of the harmlessness of chryso tile in relation to mesothelioma has been
rejected by the scientific community, as is pointed out in the submission of theWT/DS135/R/Add.1
Page 44
European Communities.  It is hard to see what Canada is recommending when it
suggests that assessments of the risk associated with "exposure to chrysotile
exclusively"  should not be based on exposure to mixtures of asbestos containing
amphiboles.
164. Canada suggests in its question that the assessments of the risk from exposure to asbestos
carried out up to now (by INSERM and by all the other official bodies which have performed such
assessments) are wide of the mark as they are all based on increases in cancer risk observed in
different studies where workers were exposed to different types of asbestos.  The models used are in
fact based on the average dose-risk ratios observed in the main studies available, the validity of which
has been deemed adequate.  Those ratios differ widely in "extreme" studies, and this may reflect the
statistical uncertainty associated with each study and/or genuine differences in risk due, for example,to the conditions of exposure or the nature or morphology of the fibres.
165. The decision to use a single average value in order to set up a dose-dependent risk model is
the most realistic option when it is wished to assess the risk to the general population of a country,
which is exposed under highly variable conditions, particularly in terms of the nature and morphology
of the asbestos fibres encountered.  While a "detailed" assessment may be justified in specific andwell-known exposure situations, a "universal" risk assessment is broadly speaking a more plausible
option in most situations.  If it was nevertheless wished to assess the risk associated with "exposure to
chrysotile exclusively ", difficult problems would be faced.  The dose-risk ratios observed in the main
studies available on exposure to chrysotile are extremely variable:  for example, in the case of lung
cancer, the dose-risk ratios are more than twenty tim es higher in the textile asbestos industry than in
the asbestos mining and milling industry.  Generally speaking, higher lung cancer risks are found in
studies concerning exposure to chrysotile than in those concerning amphiboles.
84 Which of the
dose-risk ratios does Canada consider should be chosen for risk assessment purposes?
Question 4:  Do the data from the study by Peto et al . (1998) cited by the European
Communities concern exposure to chrysotile only or exposure to amphiboles or mixtures
containing amphiboles?
166. The data from the study by Peto et al.  concern none of the specific varieties of asbestos:  they
are based exclusively on statistical models for mesothelioma mortality data actually observed in the
European countries concerned.  The study therefore deals with the fatal effects of asbestos in all its
forms.  However, in order to evaluate the role of each of the different varieties of asbestos in this
health catastrophe, it should once again be recalled that chrysotile accounts for the overwhelmingmajority of asbestos imports, particularly in France where the share of chrysotile has never been lower
than 97 per cent of all asbestos.  For that reason, chrysotile must be considered to be responsible for
most cases of mesothelioma, as is demonstrated in detail in the article by Smith  et al.
85, the very title
of which is unambiguous:  " Chrysotile asbestos, the main cause of pleural mesothelioma ".
Question 5:  Did the INSERM researchers study the question of exposure from sporadic work
on materials in which chrysotile fibres are firmly  embedded in a binding agent, so that no dust
can be formed, such as chrysotile cement?
167. This type of exposure was analysed in the INSERM report86, together with the range of
occupational exposures to sporadically high levels of pollution, which are responsible for the vast
                                                     
84 A detailed analysis of these figures will be found in the INSERM report, pages 193 to 214;  see in
particular table 3, page 200.
85 Y. Iwatsubo, et al., Pleural Mesothelioma:  Dose-Res ponse Relation at Low Levels of Asbestos
Exposure in A French Population-Based Case-Control Study,  Am.J. of Epid., 1998;148:133-142.
86 INSERM Report, pages 69-71.WT/DS135/R/Add.1
Page 45
majority of cancers due to asbestos.  Moreover, an Annex87 to the first written submission of the
European Communities sets out exposure values measured in connection with such work, which show
that levels tens or even hundreds of times higher than the prescribed limit values can be encountered.
For example, a roofing worker using a grinder out of doors to repair corrugated roof sheeting made of
asbestos-cement is subjected to a maximum exposure level of 41 f/ml, 410 times the limit value.  It isworth noting that the authorized limit values are substantially exceeded when the ISO 7337 standard
is applied.
Question 6:  Since the INSERM Report acknowledges a latency period of some decades for
asbestos-related illnesses, how can the European Communities assert that controlled use does
not work, when fewer than 25 years have el apsed since the effective implementation of
controlled use?
168. The assertion that "controlled use does not work" is based essentially on the finding that
extremely high levels of asbestos fibre are released into the atmosphere during operations on
asbestos-containing materials carried out in accordance with the ISO 7337 Standard, as well as the
practical impossibility of ensuring that the Standard is observed at all times in operations on such
materials.
88  As it is clearly established that such levels of exposure provoke cancers, it is obvious that
fatal illnesses will occur in the future as a result of  such exposures.  What Canada is suggesting in this
question is a waiting period of 25 years (and a considerable number of deaths) to confirm this patent
fact which is based on indisputable data.  Furthermore, it should be noted that the HSE (Health and
Safety Executive) study89 carried out in the United Kingdom on a population of workers in the
asbestos-processing industry, which was subjected to strict rules of "safe use" from 1969, shows thatthe application of those rules does not enable a significant excess of cancer to be avoided, even in a
sector which appears to be easy to demarcate and control.
Question 7:  Did INSERM itself estimate the ri sk level for lung cancer or did it use the 1986
EPA estimates?
169. It should first of all be pointed out that the "ris k levels" referred to indicate the increase in the
relative risk of lung cancer mortality for each additional unit of exposure to asbestos.  These levels
were estimated by neither INSERM nor the EPA:  they were actually observed in the epidemiological
studies carried out among workers in the asbestos industry.  Canada no doubt wishes to draw attention
to the "average" level (derived from all those observed in different epidemiological studies) which is
used for risk assessments and which represents the average risk.  This value serves to calculate
"theoretical" numbers of deaths that would be caused under various scenarios of exposure to asbestosin a population;  the higher the level, the greater the calculated number of deaths.  The aim therefore is
to use epidemiological models to measure the theoretical impact of such levels of exposure in the
population, for scoping purposes.  Such models ba sed on uncertain scenarios are commonly used in
many areas relating to health or the economy, for instance in order to inform decision makers about
the possible consequences of their decisions.  This is what was done by the INSERM researchers.
170. It is important for the Panel to be aware th at, prior to the INSERM study in 1996, the very
basis of which is challenged in the Canadian submi ssion, six other official expert groups (including a
Canadian group) had done similar work:
• Consumer Product Safety  Commission (USA, 1983)

3 July 1995.

Health and Safety Executive, 1996, pp. 127-152.WT/DS135/R/Add.1
Page 46
• National Research Council (USA, 1984)
• Ontario Royal Commission (Canada, 1984)
• Health and Safety Commission (United Kingdom, 1985)
• Environmental Protection Agency (EPA, USA, 1986)
• Health Effects Institute (USA, 1991)
171. INSERM carried out a thorough review and careful analysis of the risk levels used by these
different groups of experts, who had already made assessments of the risk of lung cancer caused by
exposure to asbestos.90  Selecting an average level is a complex matter given the sharp variations
observed in the different epidemiological studies (once again, it should be noted that the highestvalues are usually observed in studies concerning workers exposed to chrysotile asbestos).  It is
observed
91 that four of them selected the same value as INSERM (+1 per cent);  another selected a
lower value, albeit combined with a range of variation with a very high upper limit;  another selected
a higher value (+ 2 per cent).  It can be seen, therefore, that the choice made by INSERM is consistent
with that of the expert groups of other countries, and no attempt was made to exaggerate the risksfrom asbestos.
Question 8:  Do the European Communities acknowledge that they bear the burden of proof
under Article XX(b) of GATT 1994 and Article 2.2 of the TBT Agreement?
172. The burden to establish a prima facie violation of a provision of the GATT Agreement is on
Canada.  When the prima facie case has been made, the burden of proof passes to the defending
Member, which must in turn counter or refute the alleged inconsistency, for instance by claiming the
application of Article XX(b) of GATT.  The burden of proof and the concomitant burden ofpersuasion continue, however, to shift back and forth ("like a pendulum") throughout the entire Panel
proceedings.  The case law on the burden of proof that has been developed under Article XX(b) is not,
however, applicable in the context of the TBT Agreement (in particular Article 2.2 thereof), as
Canada's question seems to suggest.  Article 2.2 cannot be described as an exception to another
provision of the TBT Agreement.  The case law of the Appellate Body in the Hormones  case
(paragraphs 99 to 109) is more relevant in this context
92, taking into account the structure and context
of Article 2.2 of the TBT Agreement.93
Question 9:  Do the European Communities mainta in that the chemical composition of fibres is
a relevant criterion in determining the likeness of products under Article III:4 of GATT?
173. Chemical composition is certainly relevant to the extent it affects or influences the nature,
properties and qualities of the product in question.  According to GATT practice and case law, a
product's properties, nature and quality are extremely important in determining "likeness" under
Article III:4 of GATT.  Since the chemical composit ion of the fibres contained in a product is almost
certain to influence its characteristics (including its potential health effects), the EuropeanCommunities consider that criterion indeed relevant.  In addition, it is not unreasonable to assume that
the chemical composition may also affect or influence the nature or quality of the product and,
consequently, consumers' tastes.  It is hardly open to doubt that any informed consumer would very
probably refuse a product proved to be carcinogenic.  Please see also the European Communities'
reply to question 27 of the Panel.

93 The European Communities note that the case law of the Appellate Body in the case  Japan –
Measures Affecting Agricultural Products  (AB-1998-8, paragraph 126) is also relevant by analogy, where it was
held that the burden lies on the Plaintiff Member to esta blish that the measure at issue is more trade-restrictive
than necessary to fulfil the legitimate objective, taking account of the risks non-fulfilment would create.WT/DS135/R/Add.1

Question 10:  Do the European Communities rec ognize the relevance of international standards
for the establishment of technical regulations on the use of asbestos fibres?
174. Please refer to the European Communities' reply to question 37 of the Panel.
5. Questions to Canada by the European Communities
Question 1:  On what facts does Canada base it s claim that cases of mesothelioma in France are
due solely to amphibole asbestos, not to chrysotile asbestos?
175. Canada has never stated that cases of mesothelioma in France are due solely to amphibole
asbestos and not to chrysotile asbestos;  science has not yet proved beyond a shadow of a doubt that
chrysotile cannot cause mesothelioma.  There is, however, a great deal of scientific evidence that this
is, in fact, the case.  On the other hand, the link between exposure to amphibole fibres, particularlycrocidolite, and development of mesothelioma has been clearly established.  Since the disease was
identified in the late 19
th Century, there have been many reported cases which could not be linked to
exposure to asbestos.  According to Dr. Premysl V. Pelnar in a study published in the Scandinavian
Journal of Work, Environment & Health  in 1988, it has been proved that many agents other than
asbestos cause mesothelioma in laboratory animals, including biological agents (e.g. the SV 40 virus),chemicals (e.g. polysilicone plastics and diatomaceous earth), physical chemical products (glass fibre,
erionite-zeolite, tremolite and attapulgite), and physical agents such as x-rays.  It has also been proved
that exposure to some of these agents (erionite- zeolite, tremolite and x-rays) causes mesothelioma in
humans.
94  See also the answer to question 3 by the European Communities to Canada.
Question 2:  Can Canada give its figures for amphibole asbestos imports and consumption
before the ban?
176. First of all, the question contains an error of fact concerning the ban on use of amphiboles in
Canada that needs to be rectified.  Under the Hazardous Products Act/Hazardous Products
(Crocidolite Asbestos) Regulations , "The importation of crocidolite asbestos fibres shall be (…)
restricted and regulated", but not banned.  Under the regulations, the importation of crocidolite
asbestos fibres for the manufacture of diaphragms, chloralkali and certain acid and temperature
resistant products (e.g. waterproof seals) and of ce rtain products containing the fibres (e.g. asbestos
cement pipes) is permitted subject to the following conditions:  (i) a notice must be sent to the Federal
Department of Industry, which informs the provincial organization responsible for enforcing the
Occupational Health and Safety Act ;  (ii) the notice must include the import date, the port of entry, the
quantity being imported, the address of the premises where the product is to be used, etc.;  (iii) theproduct must be labelled appropriately.
177. However, Canadian statistics on asbestos imports do not differentiate among the various types
of asbestos fibres, so imports of chrysotile, amosite and crocidolite are combined in one figure in the
available data.  Data on Canadian consumption of asbestos fibre have been available since 1982, the
year that annual surveys began.  Low levels of amosite fibre consumption were reported for the period1982-85, but no crocidolite consumption was reported.
Question 3:  Does Canada have any scientific  evidence to suggest th at materials other than
asbestos may cause mesothelioma in industrialized countries?
178. Canada has access to the same scientific data that is available to the international community
at large, including France on "other potential causes of mesothelioma in industrialized countries".

Page 48
Canada feels compelled to inform the European Communities of the considerable body of evidence
contradicting their statement that "asbestos in all forms (amphibole and chrysotile) is the only known
factor that can cause mesothelioma or pleural cancer".  A number of studies suggest other potential
risk factors that may have been underestimated in epidemiological studies in industrialized countries.
We take this opportunity to correct the European Communities' simplistic definition of mesothelioma:"mesothelioma is a cancer of the pleura … ".  In fact, malignant diffuse mesothelioma is a cancer of
the mesothelial cells of the pleura, the pericardium and the peritoneum.  Furthermore, peritoneal
mesothelioma is much more typical of exposure to amphiboles than pleural mesothelioma.
179. A number of artificial fibres cause mesothelioma when they are injected into the pleura and
peritoneum of laboratory animals.  It should also be noted that the International Agency for Research
on Cancer (IARC) has classified refractory ceramic fibres as probable carcinogens, partly because of
instances of mesothelioma induced by inhalation and injection in animal studies.  The SV 40 virusreadily induces mesothelioma when injected into an imals;  studies suggest that the virus contaminated
anti-polio (poliomyelitis vaccines) from 1955 to about 1963 and may induce mesothelioma with or
without the help of asbestos fibres.  Some studies of humans report the presence of the simian SV 40
virus in the biological tissue of mesothelioma victims.  Ionizing radiation used in cancer therapy, as
well as, perhaps, occupational exposure to radiation have induced mesothelioma.
95  In addition, a
large proportion of mesothelioma cases (as high as 25 per cent) are not attributable to exposure to
asbestos;  they may have been caused by hidden (unidentified but real) exposure to asbestos, but the
figures suggests that there are other significant causes that cannot be countered by targeting exposure
to asbestos alone.  For example, erionite has been shown to be even more toxic than crocidolite in
causing mesothelioma:  it has killed large numbers of villagers in Turkey.  Erionite is a mineral fibrebut does not belong to the asbestos family, wh ich suggests that fibres with similar physical
characteristics could pose a health threat to other population groups.  Finally, we wish to remind the
European Communities that the issue at hand is the ban on chrysotile products and that there are
mesothelioma risk factors other than chrysolite, particularly all the amphibole fibres and flockings
placed around furnaces, boilers and high-temperature pipes.
Question 4:  Does Canada dispute that chrysotile asbestos is a proven carcinogen in humans - in
general?  In the case of lung cancer?  In the case of mesothelioma?
180. Canada does not dispute that chrysotile causes lung cancer.  However the way in which
exposure to chrysotile asbestos may increase the risk of lung cancer has not yet been fully explained,
and might only be indirect.  First of all, Canada maintains that the risk is dependent on the intensity
and duration of exposure and that there is a level of risk below which the risk, if any, is undetectable.According to Churg on this subject:
"As a practical matter, the data indicate that chrysotile will not produce mesotheliomas in those
exposed to any current or recently regulated numbers of chrysotile, and certainly not in those exposed
to chrysotile encountered at environmental levels" .96

181. The risk may become detectable in cases of long-term exposure to high levels, but it is then
by no means certain whether the chrysotile acts as a direct carcinogen or by causing the formation of
pulmonary fibrosis, which would be a precursor of  neoplasia.  In other words, exposure must be
sufficient in intensity and duration to induce pulmonary fibrosis, which predisposes the pulmonary
parenchyma to a higher risk of cancer.  Regarding asbestos-related mesothelioma, a number of studieshave demonstrated cogently that this type of cancer is almost exclusively linked to exposure to
amphiboles.  Cases of mesothelioma in chrysotile asbestos miners in Quebec are relatively rare - in a
cohort of 11,000 workers who were very carefully monitored (in the McDonald study), there were at
most fifty or so cases over several decades.  Exhaustive research into their employment history
revealed that most of the cases were related to short-term exposure to commercial amphiboles.  For
example, during the Second World War, some of th e miners with mesothelioma had worked in plants
manufacturing products for the allied forces and amphiboles imported into Canada had been used tomake a variety of products, including gas masks, to assist in the war effort.
97
Question 5:  How does Canada explain the fact that the risk of mesothelioma is seven times
higher than average for women living near ch rysotile mines in Quebec?  (Note that this
population group was the subject of a special study because, in its case, the exposure is
environmental, not directly occupational).
182. The women in the towns of Thetford Mines and Asbestos have been continuously exposed
from birth to asbestos concentrations of 1 f/ml. or more.  Given that the risk of mesothelioma
increases by approximately the power of 3 in relation to the time that has elapsed since exposure,
these women have had more time to develop a detectable risk of mesothelioma than many workers inother parts of the asbestos industry.  Even so, their risk level seems to be at least 20 times lower than
predicted by the Environmental Protection Agency (USA) and INSERM models.
183. More specifically, it should be borne in mind that some 75 per cent of the women in this
study
98 lived with an asbestos worker, of whom a small minority worked with amphiboles,
particularly crocidolite.  Furthermore, some 5 per cent had themselves already worked in the asbestosindustry as "sheddeuses" or "gobeuses" or had worked in workshops for repairing jute sacks which
had contained crocidolite or had worked at home for the asbestos industry repairing jute sacks used to
transport amphiboles.  Finally, the results to which the EC refers concern deaths from pleural cancer.
Since then, researchers have compiled and checked the diagnosis in pleural mesothelioma cases, thus
providing a better measurement of the risk arising from asbestos.  The authors of the study have
collected but not yet analysed the exposure histories of cases of pleural mesothelioma in women
(more than ten so far, and not merely the seven mentioned in the 1997 publication).
184. Preliminary analyses indicate that a certain number of mesothelioma cases were exposed to
crocidolite or amosite more than thirty years before the onset of the disease (Camus and Siemiatycki,
personal communication, 1999).  The other mesotheliomas may be attributable to a long period of
induction, following a massive build-up since childhood, of continuous environmental exposure or
exposure in the home (living with an asbestos wo rker) to commercial chrysotile exceeding 1 f/ml.
The women's cumulative exposure was equivalent to between 100 and 300 fibre years/ml. for asbestos
workers.
Question 6:  Does Canada disagree that most cases of mesothelioma occur in industrialized
countries in occupations involving intermittent ex posure to asbestos, specifically those where the
worker has to work with asbestos containing materials?

of Lung Cancer , N. Eng.l J. Med .  1998;  338:  1565-71.WT/DS135/R/Add.1
Page 50
185. Nowadays, most cases of mesothelioma in the industrialized countries occur in occupations
other than mining and manufacture of asbestos products because workers in those occupations are
exposed to amphiboles in poorly controlled work areas.  The workers who remain at risk, working in
the construction sector, are specifically those who are most exposed to flocking and friable products
made of asbestos mixes containing amphiboles or co mposed entirely of amphiboles.  This situation is
completely different from the case of workers in ch rysotile mines and in manufacturing plants where
only chrysotile is used.
Question 7:  Because Canada did not provide the health statistics requested at the consultative
meetings in July 1998, France used gross data on the worldwide situation published by the
WHO to calculate the incidence of mesothelioma in Canada and Quebec from 1978-1992.  Could
Canada provided its own recent health statistics (since 1992) on mesothelioma deaths in Canada
and Quebec?
186. See above, reply to question 9 by the Panel to Canada.
Question 8:  Can Canada explain how the safe use of chrysotile can have resulted in the
following observations from a study conducted in the Montreal area:
- A risk of mesothelioma more than 14 ti mes higher than the average for persons
"significantly" exposed to chrysotile asbestos?
- A risk of lung cancer 2.3 times higher than the average for people
"significantly" exposed to chrysotile asbestos?
- A risk of mesothelioma almost 12 times higher than the average for construction
workers?
187. The purpose of this major case-control study, which was conducted on 4,500 cancer cases
diagnosed in hospitals in the Montreal area between September 1975 and June 1985, was to identify
potential associations for follow-up from among the tens of thousands of possible associations
between 23 groups of cancer, 98 occupational groups and 293 substances.  As the authors state, the
study and the analysis were designed to establish hypotheses, not to verify specific hypotheses.  The
downside of this greater sensitivity is a tendency to overestimate associations and to obtain more
"false positives"  The authors therefore recommend that each reported association should be
interpreted with prudence and caution (page 304).
188. The main limitation of the reported analyses is that they are "univariate":  they consider only
one occupational exposure at a time and do not evaluate the effects of other concomitant occupational
exposures (page 119).  This problem is particularly significant in the case of chrysotile.  The workers
in the study who were exposed to chrysotile were also exposed to amphibole fibres, crystalline silica,
cement dust, PAH's and alkanes, wood dust, solvents and pyrolysis fumes (pages 50-51).  Seven ofthe ten substances in the study were associated with mesothelioma and all ten were associated with
lung cancer.  Thus the reported associations between mesothelioma, lung cancer and chrysotile do not
isolate the level of risk associated with chrysotile itself from the compound effect of several other risk
factors.  The authors thus caution against oversimplified interpretations (page 301):  "[A] much more
important problem is the fact that the association between cancer and one occupational substance maybe confounded by other occupational substances."  The problem may be even more serious in respect
of mesothelioma, because the study included only a very small number of cases (12 cases).
189. Regarding lung cancer, the study also recognizes the possibility of a residual effect of
smoking and a paradox that the researchers cannot explain:  the absence of an association between
lung cancer and exposure to amphiboles.  This anomaly illustrates the difficulty in population case-WT/DS135/R/Add.1
Page 51
control studies of distinguishing between past exposure to chrysotile and amphibole.  The same
problem was underlined in the article by Iwatsubo et al. , cited by the European Communities99 and in
the preface100 by Siemiatycki and Boffetta (IARC) to the Iwatsubo study.  Finally, because the study
was restricted to cancers occurring between 1979 and 1985, and the induction/latency periods for lung
cancers and mesothelioma are several decades, the exposures that may have caused the cancersoccurred before controlled use measures were applied.  This data can, therefore, in no way provide a
basis for assessing the affect of controlled use of chrysotile which was introduced in the 70's.
Question 9:  Why does Canada think that the controlled use of amphiboles is not technically
feasible (since it has banned this type of asbestos)?
190. The distinction is based on the proved lower toxicity of chrysotile compared with amphiboles
and the application of principles inherent in international standards on the controlled use of asbestos.
Question 10:  In its submission, Canada acknowledges that "certain uses for which exposure
cannot be controlled to an acceptable degree should be banned".  Could Canada specify to
which uses it is referring?
191. The guiding principle in controlled use is th e elimination of any use involving a risk that
cannot be adequately controlled.  Thus the Canadian Hazardous Products Act prohibits the use of the
following:
(a) Textile fibre products that are to be worn on the person and that contain asbestos
fibres, other than products that are designed for the purpose of affording protection
from fire and heat hazards and constructed in such a way that ensures that theasbestos fibres will not, on reasonably foreseeable use, become separated from the
products;
(b) asbestos in spray form except products composed of a mixture of asbestos fibres and
bituminous and resinous-based binding materials where the fibres are encapsulatedwith the binding during spraying and the resulting materials are not friable after
drying;
(c) products composed of or containing asbestos for use by a child in learning and
playing and made in such a way that asbestos may become separated from the
products;
(d) products composed of or containing as bestos for use in modelling or sculpture;
(e) dry-wall joint cements or compounds or sprackling or patching compounds,
composed of/or containing asbestos, that are made in such a way that airborne
asbestos may become separated from the products during the preparation of theproducts, other than preparation at the manufacturing level, or during the application
of the products or at any time thereafter up to and including the repair and removal of
the products;

Question 11:  The enormous amount of work in  France on airborne particles in the workplace
has shown no evidence of chemical changes in ch rysotile asbestos fibres released during high-
speed machining of materials containing asbestos .  Can Canada provide evidence of changes in
the chemical composition of chrysotile asbestos during high-speed machining?
192. Canada is surprised that this question should be asked, because the answer was given at the
first substantive meeting of the Panel, with relevant supporting references.  In any case, given that the
question concerns fibres released during dry, high-speed machining of high-density materials, the
operations concerned clearly do not comply with controlled-use safety procedures.
Question 12:  Can Canada state exactly when the "modern" use of asbestos began?  How does
Canada characterize the so-called "modern" characteristics of chrysotile cement products?
193. The advent of the use of "modern" asbestos products was a gradual process that began in the
1970s with the phasing out of uses in which asbestos fibres could readily be separated from thefinished product, as in the case of friable insulating materials and flockings, toys and unprocessed
textiles.  The manufacture of products containing amphibole-type fibres was also phased out because
they were recognized as more harmful.  In short, a distinction must be made between two periods:  the
first is characterized by the use of amphibole fibres and uses in which asbestos fibres could be easily
separated from the finished product;  the second is characterized by the prohibition or restricted use ofamphibole asbestos and by the advent of non-friable products, i.e. products in which fibres are firmly
bound to a matrix and are highly unlikely to be released in biologically significant concentrations.
The distinction is a fundamental one.  It should nonetheless be noted that non-friable products in
which chrysotile is encapsulated in a matrix, as in the case of chrysotile cement, were manufactured
and used during both periods.
194. The industrial diseases attributable to asbestos that are now occurring in Europe and
North America are associated with so-called "old-style" products and amphiboles.  This fundamental
distinction has been recognized by the International Labour Organization in Convention 162
concerning Safety in the Use of Asbestos, by the World Health Organization and in the regulations of
most countries.  Even though they have been manufactured for nearly 100 years, chrysotile cement
products meet the "modern use" criterion because the fibres are encapsulated in a cement matrix and
are not released in significant quantities as long as simple controlled-use procedures are followed.More recently, new procedures have been introduced to eliminate the use of crocidolite fibres in the
manufacture of pipes, and countries such as Japan and France have developed new chrysotile cement
products manufactured by extrusion or covered with a lustre coating.  These advances have in no
small measure helped to make products not only safe but also more attractive.
Question 13:
(a) Has Canada established a monitoring enforcement mechanism for the application of
"controlled" use measures, including maintenance work?
195. In Canada, controlled use has entailed the prohibition of friable products containing asbestos
and the adoption of measures to protect the health and safety of workers exposed to asbestos.  In
general, the protective measures are a provincial responsibility, and in Quebec they come under the
Regulation on the Quality of the Work Environment and the Safety Code for the Construction
Industry, which are administered by the Occupati onal Health and Safety Commission (CSST).  Both
sets of regulations cover working conditions in chrysotile mines, asbestos product manufacturingplants, and firms specializing in maintenance and removal of asbestos flockings in Quebec.WT/DS135/R/Add.1
Page 53
196. Regarding the health and safety of workers specializing in maintenance and repairs
(plumbing, electricity, air-conditioning, etc.) in buildings containing asbestos flockings, the CSST is
in the process of implementing a programme for the prevention of occupational diseases associated
with exposure to asbestos.  The programme is aimed at management and employees in this sector of
activity and its purpose is to inform them about the required prevention measures and give them theappropriate training.
197. In addition, the Regulation on Air Quality and the Regulation on Solid Waste, issued by the
Department of the Environment of Quebec, state respectively the environmental measures to be taken
regarding airborne asbestos and the standards governing burial of waste containing asbestos.  Officers
of the CSST and the Department of the Environment monitor and enforce the application of all these
measures as part of their regular duties, in the same way as they enforce provisions for the control of
other substances considered to pose a public health risk and a threat to the health of workers.  Themeasures make it possible to control asbestos throughout its useful life, from the time it is mined to
the time it is buried.
(b) What monitoring mechanism did Canada set up to check whether the applicable ISO
standards were being followed in Canada and in countries with companies that signed the
"Agreement"?
198. In their respective areas of jurisdiction, the regulations of the Canadian Government and the
provincial governments provide that the use of chrysotile, at all stages from extraction to use of the
finished product, is to be controlled in such a way as to minimize exposure to fibres.  Furthermore,
they cover the maintenance of buildings containing various types of asbestos and provide for a varietyof measures based on the type of work being done and the type of asbestos fibre involved.  In most
provinces and in buildings under the jurisdiction of  the Canadian Government, property owners are
required to maintain friable materials in good condition and to inform employees in advance in the
event that they may be exposed to such products during maintenance work, repairs or renovations.
199. In the Agreement on the responsible use policy, there is no question of any intent to check
how each business uses its products containing chrysotile.  The aim of the Agreement is to ensure that
users manufacturing finished products, where the health  risk is the highest, comply with national and
international occupational health standards.  The relevant passage of the Canadian submission,
concerning standards for installing asbestos cement products, was intended to show that the safe use
of asbestos cement products is possible and that this fact is recognized by international organizations
such as the International Organization for Standardization.  So Canada is surprised at European claims
that safe use is impossible, particularly in a country like France.
Question 14:  Could Canada clarify whether asbestos producers have already had occasion to
stop exports to countries after determining that businesses using their products were not
complying with the "Agreement"?
200. Stopping chrysotile sales by producers from signatory countries is the measure of last resort
in cases where a consumer is not complying with national regulations and makes no effort to improve
working conditions in the business concerned.  Under the Agreement, producers must first provide
businesses with technical support in order to reduce concentrations of airborne respirable fibres.
Measures include the implementation of working procedures, the installation of dust collectors, and
the purchase of air sampling and analysis equipment.   To enhance the effectiveness of their actions,
Canadian chrysotile producers have also used the services of international organizations such as the
Asbestos Institute and the Asbestos International Association for plant inspections, training and the
collection of data on airborne fibre rates on a continuing basis.  In this context, more than
100 technical visits have been made over the last five years, along with training courses in Canada
and in a number of consumer countries.WT/DS135/R/Add.1
Page 54
201. Numerous contacts have been established with the governments of chrysotile importing
countries to raise their awareness of the work being done by the producers, often with the assistance
of trade unions and the Government.  In this way, signatories to the Agreement can be assured that
non-compliant businesses cannot obtain supplies from other sources.  As a result, some countries have
decided to issue import licences so as to ensure that every user complies with national regulations.
However, in the few cases where users do not follow controlled-use procedures, Canadian producers
refuse to sell or stock shipments of the fibre.  This  has been the case, in particular, of certain users in
Mexico, Argentina, Korea, China and Egypt.
Question 15:  How can Canada claim, on the one hand, that amphibole-asbestos and chrysotile-
asbestos are very different products and, on the other, claim at the end of its submission, that
chrysotile-asbestos and substitute products are like products?
202. The distinction made by Canada between amphibole fibres and chrysotile fibres is intended to
differentiate between the fibres according to their pathogenicity, on a medical and scientific basis.
The objective is not to determine whether they are "like" for the purposes of any provision in the
TBT Agreement or GATT but to determine whether one is more dangerous than the other.  In this
context, the capacity for inducing mesotheliomas and the carcinogenicity of the different types of
fibres are clearly relevant to determining the respective pathogenicity levels of amphiboles and
chrysotiles.
203. Regarding Canada's arguments on like products  under Article III:4 of GATT and Article 2.1
of the TBT Agreement, the scientific question of pathogenicity opens the door to consideration of
broader factors such as the properties, nature and quality of the product, its tariff classification andend use.  Canada sees no contradiction between making a distinction between two types of fibre to
provide a scientific demonstration of differences in pathogenicity, on the one hand, and applying
criteria based on WTO and GATT decisions for the purposes of a legal argument on like products on
the other.  Canada is of the opinion that likeness under GATT or the WTO is a different issue from the
assessment of pathogenicity.
Question 16:  If Canada were to admit that there was a difference in toxicity between two
products, would it accept the idea that they were not like products?
204. No.  First, it should be noted that the toxicity of a product is not a recognized criterion for
analysis of likeness.  In Canada's opinion, the fact that two products have similar toxicities is not an
element of their likeness under Article III:4 of GATT or Article 2.1 of the TBT Agreement.  Benzene,
for example, is not "like" crystalline silica just because they are both carcinogens.
205. Conversely, where it is clearly established that the toxicities of two products are different, it is
not inconceivable that the two products could still be "like" for the purposes of Article III:4 of GATT
or Article 2.1 of the TBT Agreement.  By way of example, wine and vodka, in equal quantities, have
very different effects on health and yet they are considered to be "like" products.
101
Question 17:  On what scientific basis did Canada decide not to follow the recommendations
made by the ILO in 1986 and those made by WHO in 1998 for asbestos, including chrysotile
asbestos, to be replaced with less hazardous products?
206. To answer this question, we would first like to quote Article 10 of ILO Convention 162, to
which the European Communities refer in discussing substitute products:  "where … technicallyfeasible, national laws or regulations shall provide for … the replacement of asbestos or of certain
                                                     
101 Japan – Customs Duties, Taxes and Labellin g Practices on Imported Wines and Alcoholic
Beverages , L/6216, adopted 10 November 1987, BISD 34S/92, paragraph 5.6, page 131.WT/DS135/R/Add.1
Page 55
types of asbestos or products containing asbest os by other materials or products or the use of
alternative technology, scientifically evaluated by the competent authority as harmless or less
harmful; ….".  The concept of substitution approved by WHO is identical to the one conveyed here:
it must be proven that the substitute products are harmless or less harmful.  The fact is that the
scientific community still questions the harmlessness of most of the substitutes.  Thus, INSERMstated that "any new fibre proposed as a substitute for asbestos or for any other use must be suspected,
a priori, of being pathogenic because of its structure but that this does not preclude [the requirement]
for analysis of the possible consequences of its physico-chemical characteristics."
102
207. Given the substantial latency period (between 15 and 45 years for asbestos) between exposure
to a pathogen and the development of disease, it is impossible to make a definitive assessment of the
carcinogenic potential of substitute fibres which came on to the market only recently.  However, a
number of recent studies cast doubt on the harmlessness of these fibres.  As long ago as 1993, in areport entitled Selected Synthetic Organic Fibres , the World Health Organization's International
Programme for Chemical Safety (IPCS) identified the para-aramid fibre as being respirable and
biopersistent, two criteria associated with toxic potential in a substance.  The same applies to most
replacement fibres.  Given the lack of knowledge on the subject, it would be premature to press on
blindly with substitution.
Question 18:  Why has Canada not instituted similar proceedings against other countries that
have imposed similar bans on asbestos, such as Iceland, Norway, Denmark, Switzerland and
New Zealand?
208. Canada could have taken action and is entitled to take action against similar measures
previously introduced by other countries, and in particular by seven other members of the European
Communities.  However, it has decided, for the time being, to confine itself to the "model case" of
France, basically for the following reasons:
• France is the first European country to have banned asbestos since the creation of the
WTO and the introduction of the new dispute settlement rules;
• France has switched from a policy of controlled-use of asbestos (precisely the one
advocated by Canada) to a diametrically opposite one – a total ban – even thoughthere is no new scientific data;  and
• the procedures under the Agreement do not include any mechanism for combining
similar or identical legal action.
B. 
QUESTIONS AT THE SECOND SUBSTANTIVE MEETING (20-21 JANUARY 2000)
1. Questions by the Panel to both parties
Question 1:  Is the concept of "like product" in the meaning of Article III:4 of GATT identical
to that contained in Article 2.1 of the TBT Agreem ent?  In this context, what precisely, in your
opinion, is the relevance of the criterion of the effects of the product on human health in the
context of the two provisions?
(i) Reply by Canada
209. Article 2.1 of the TBT Agreement reaffirms the obligation concerning national treatment
(Article III:4 of GATT) and the obligation of most -favoured-nation treatment (Article I:1 of GATT).
                                                     
102 See INSERM, Summary Report – Effects on Health of  Asbestos Substitute Fibres, page 2.WT/DS135/R/Add.1
Page 56
In the case of the obligation concerning national treatment, we consider that Article 2.1 of the
TBT Agreement and Article III:4 of GATT contain the same type of prescription:  not to treat
imported products less favourably than like national products.  The only difference between the two
provisions is that Article 2.1 applies only to technical regulations while Article III.4 of GATT applies
to "all laws, regulations and requirements [ … ]".  From that it follows that the concept of likeproducts in the meaning of Article 2.1 of the TBT Agreement is identical to that contained in
Article III:4 of GATT and that the criteria which are used to identify the range of like products under
Article III:4 of GATT are the same as those which are used to identify the range of like products in
Article 2.1 of the TBT Agreement.  These criteria do not include the effects of the product on human
health and we consider that they are not relevant in this case.
210. According to the Appellate Body in the case of Japan – Taxes on Alcoholic Beverages
103, the
report of the working group on Border Tax Adjustments  set out the principle for interpretation of the
formula "like products" in general in the various provisions of GATT 1947.  It must be interpreted on
a case by case basis using criteria such as the product's end-use in a given market, consumers' tastes
and habits, which change from country to country, and the products properties, nature and quality.104
This approach has been followed in almost all Panel reports which have been adopted since the oneconcerning border tax adjustments.
105  We have followed this principle in developing our arguments
that chrysotile fibre and cellulose, PVA, glass fibres as well as chrysotile-cement and fibro-cement are
like products pursuant to Article III:4 of GATT and Article 2.1 of the TBT Agreement.106  In the same
case, Japan Taxes on Alcoholic Beverages , the Appellate Body implied that other criteria can also be
utilized to identify the range of like products within the context of a particular provision of the
multilateral trade agreements of the WTO Agreement.107
211. The example of another criterion frequently used in previous Panel reports to determine
whether products are like is the tariff classification.108  We have followed this example in the present
case and invoked the uniform classification in the tariff nomenclatures of the harmonized system as a
criterion to confirm that chrysotile fibre and cellulose, glass and PVA fibres, as well as
chrysotile-cement and fibro-cement,  are like products.  The toxicity of a product, however, has neverbeen taken as a criterion for determining whether products are like.  Moreover, in this case, the effects
of the substitute fibrous products on human health are too little known and uncertain to constitute a
criterion which could assist the Panel in identifying the range of like products.  Consequently, we are
of the opinion that the Panel should only examine the criteria defined by previous practice of GATT
on which we have relied in our arguments.  We refer the Panel to our second written submission in
which we stated that the effect of a product on human health is not a criterion that should be used to
determine whether products are like.
109  Two products may be similarly toxic and not be like in the
meaning of Article III:4 of GATT or Article 2.1 of the TBT Agreement.  Conversely, assuming that it
is clearly established that two products do not share the same toxicity, they may still be like for the
purposes of Article III:4 of GATT or Article 2.1 of the TBT Agreement.

212. We reiterate our replies to questions 15 and 16 by the European Communities in which we
explain that the scientific question of the pathogenicity of the fibres has no place in the context of an
argument to show what is like pursuant to Article III:4 of GATT 1994 or Article 2.1 of the
TBT Agreement.  Instead, the broadest and most general criteria contained in the case law, such as
characteristics, nature and quality of the product, tariff classification and product's end use should beapplied.
110  Chrysotile fibre is indisputably different from amphibole fibres when it comes to
toxicity111, but we consider that chrysotile fibre and amphibole fibres are like products.  Just as
chrysotile fibre and amphibole fibres are like products although amphibole fibres are much more
toxic, so PVA, glass and cellulose fibres and chrysotile fibres are like products by virtue of their
characteristics, nature and quality, even if we do not know, given the present state of scientific
research, the actual toxicity of each of these substitute fibres.112  In our view, the effects of chrysotile
fibre on human health, in the same way as those of  substitute fibres, which in most cases are not
known, are not relevant to the issue.  The Panel shou ld not take them into account in the context of its
examination of the various characteristics of these products to establish whether they are like pursuant
to Article III:4 of GATT or Article 2.1 of the TBT Agreement.
(ii) Replies by the European Communities
(a) No, the concept of "like products" in Article III.4 of GATT is not identical to the concept of
"like products" contained in Article 2.1 of the TBT Agreement for the following reasons.
213. The concept of "like products" has to be interp reted in accordance with the customary rules of
interpretation of public international law, that is in accordance with the ordinary meaning to be givento this concept in its context and in the light of its object and purpose.
113  It should also be recalled that
the Appellate Body has held that the concept of "likeness" is a relative one that evokes the image of
an accordion.  The accordion of "likeness" stretches and squeezes in different places as different
provisions of the WTO Agreement are applied.  The width of the accordion in any one of those places
must be determined by the particular provision in which the term "like" is encountered as well as bythe context and the circumstances that prevail in any given case to which that provision may apply.
No one approach to making a judgement will be appropriate for all cases.
114  
214. First of all, the context  in which this term appears is different in the two Articles.  The context
of GATT Article III.4 is clearly different from that of Article 2.1 of the TBT Agreement.  The TBT is
a specific Agreement that elaborates further on the objectives of GATT 1994.  Whereas the obligation
of national treatment and the concept of "likeness" in Article III.4 of GATT 1994 have a fairly wide
application "in respect of all laws, regulations and requirements affecting internal sale, offering forsale, purchase, transportation, distribution or use", the obligation of national treatment and the concept
of "likeness" in Article 2.1 are confined by the specific object and purpose of the TBT Agreement,
that is it applies only "in respect of technical regulations".  Thus, Article 1.2 of the TBT Agreement
provides that for the purposes of that Agreement the meaning of the terms given in Annex 1 thereto
applies.  Also the title of Article 2 reads "Preparation, Adoption and Application of TechnicalRegulations by Central Government Bodies".  These phrases may not be read so expansively as to
subvert the purpose and object of Article 2.1 and of the TBT Agreement in general.  It follows that
because the TBT Agreement deals only with technical regulations, standards and conformity

assessment procedures related to products or processes and production methods115 the concept of
"likeness" is by definition narrower than that of Article III.4 of GATT as regards the legal context
within which and the object and purpose for which the determination of "likeness" is to be made.  In
other words, the legal context as well as the object and purpose determine inevitably the coverage of
the term "like":  not all like products are covered by Article 2.1 of the TBT Agreement, but only thoseto which the technical regulation was intended to apply.
215. Secondly, the European Communities dispute Canada's claim that the French Decree in
question lays down a technical regulation in the sense of the TBT Agreement.  This is clearly not the
case of the general, horizontal prohibition of any kind of asbestos as well as of the limited and
transitional exceptions laid down in Article 2 thereof, as shown in our written and oral submissions.
However, if we suppose, for the sake of argument, that the French Decree did lay down a technical
regulation, such a regulation would only have been applicable to asbestos as such and toasbestos-containing products.  Indeed, the French Decree in question has laid down no technical
regulation whatsoever for the so-called "substitute" products as claimed by Canada.  Canada's
argument that the so-called "substitute" products are, for the purpose of Article 2.1 of the
TBT Agreement, "like" asbestos and asbestos-containing products runs counter to the very object and
purpose of the TBT Agreement and leads to unacceptable results from the regulatory point of view.This is because such an interpretation is likely to restrict unreasonably the regulatory freedom of the
WTO Members and would introduce uncertainty and unpredictability into international trade for no
valid reason.  As a general rule, Members introduce technical regulations, standards and conformity
assessment procedures for the purpose of achieving a legitimate objective (e.g. safety).  The object
and purpose of the TBT Agreement is to guard against "unnecessary obstacles to international trade"(fifth preambular paragraph) in the products covered by the technical regulation, not in the potentially
vast category of alternative/substitute products, because normally no government is in a position to
know in advance the category of products that are likely to be affected by the adoption of the
technical regulation.
116   The concept of "like" products cannot be given so broad a reach as effectively
to underline the autonomous right of Members to determine their level of health protection.  In otherwords, to interpret so broadly the concept of "like" products is bound to present Members' regulatory
authorities with the dilemma of abandoning the pursuit of a legitimate objective (e.g. safety) for the
sake of avoiding a possible adverse finding under Article 2.1 of the TBT Agreement, even if there
exist only a few alternative/substitute products of national origin. Such a paradoxical result can surely
never have been intended by the WTO Members.  It is contradictory and unreasonable to judge
"likeness" on the basis of the possible effects of the technical regulation on the imported (prohibited)
product, as compared to the alternative/substitute products of national origin, because a technicalregulation by definition, almost always, entails different effects (negative or positive) on those
products (of whatever origin) which do not conform with the technical regulation in question.
216. Thirdly, since the context, object and purpose of Article 2.1 of the TBT Agreement is
different from that of Article III:4 of GATT, th e four criteria usually used by panels to judge
"likeness" on a case-by-case basis in the context of Article III of GATT (i.e. the product's end uses,consumers' tastes and habits, the product's properties, nature and quality, and tariff classification) may
be applied in the context of Article 2.1 of the TBT Agreement but only in the light of the purpose of
the technical regulation under consideration, i.e. in order to identify only whether the imported
asbestos and asbestos-containing products receive, in respect of the technical regulation in question,
treatment less favourable than that accorded to various asbestos  (different types of amphiboleasbestos, chrysotile, etc.) and asbestos-containing products (brakes, various asbestos-containing
cement products, etc.) of national origin.
                                                     
115 See Annex 1, point 2 of the TBT Agreement.
116 The European Communities note that, as a matter of fact, a general and horizontal prohibition of a
given product (as in this case) is by definition likely to increase (rather than restrict) trade in
alternative/substitute products regardless of their origin.WT/DS135/R/Add.1
Page 59
(b) As the European Communities have explained117 when it has been scientifically established
that a product is dangerous to human health, this finding attributes a special internal and/or external
characteristic to the product in question that should be taken into account in defining "likeness" in
both Articles. Indeed, the scientifically established dangerous nature of a product (like that of any
kind of asbestos) necessarily affects the normal criteria used by panels to define "likeness", because:
- The product's very properties, nature and quality are necessarily affected, in the sense
that they are not the same as those of a safe or safer identical or alternative or
substitute product.  For example, an apple that contains a poisonous pesticide can
never be "like" a safe apple of the same or different variety or a safe orange, when
one would otherwise consider apples and oranges "like" products for the purpose of
Article III:4 of GATT.
- The product's end uses are also different, because a product that has been
scientifically shown to be dangerous to human health (e.g. an apple that contains a
poisonous pesticide or any type of asbestos) usually does not have the same end uses
as those of a safe or safer identical or similar or substitute product.
- The consumers' or end-users' tastes and habits are also bound to differ in the case of a
product that has been scientifically shown to be dangerous to human health (e.g. an
apple that contains a poisonous pesticide or any type of asbestos) and a safe or safer
identical or similar or substitute product.
217. In reality, a product that has been scientifically shown to be dangerous to human health
attributes to that product a specific characteristic that makes it unlike any other product of the same
family or category (e.g. apple or asbestos) or similar or alternative or substitute products (e.g. orange
or PVC fibrous product).  That kind of dangerous product should not be put into international tradeand no importing country should have to rely on Article 2.2 of the TBT Agreement, for example, or
the exception provisions of Article XX to justify any restriction on imports.
118  It follows that the
dangerous character of a product to human health is of particular relevance in the context of
Article III:4 of GATT in deciding "likeness".  In the context of Article 2.1 of the TBT Agreement, the
dangerous character of a product to human health is also highly relevant because, in the light of the
object and purpose of a technical regulation, the protection of human health is a legitimate objective
that may be taken into account in the course of its preparation.  This is particularly true, if the conceptof "like" products in the context of Article 2.1 of the TBT Agreement is to be given the very wide
meaning advocated by Canada.
Question 2:  Is it possible for a measure to fa ll partly within the scope of the TBT Agreement
while other elements of the same measure would come under GATT?
(i) Reply by Canada
218. As the Appellate Body indicated in EC - Regime for the Importation, Sale and Distribution of
Bananas
119 and in Canada - Certain Measures Concerning Periodicals120, it is possible that a
measure, because it has several aspects, could be examined under more than one WTO agreement.
                                                     
117 See above Section III.C.2.(b)(I) above.
118 The European Communities note that if such a dangerous product to human health is allowed to be
imported by a Member, this is most likely because either the dangerous nature of the product is not known, notdetectable or not visible, or the importing Member has a level of health protection that can cope with a risk of
human health of this nature or degree.
119 Report of the Appellate Body, para. 221.
120 Report of the Appellate Body, page 19.WT/DS135/R/Add.1
Page 60
Conceptually, then, it is possible that certain aspects of a particular measure are covered by the
TBT Agreement, while other aspects of the same measure, which are not covered by the TBT
Agreement, are covered by GATT.  However, taking account of the facts of this case, Canada is of the
opinion that the French measure is a technical regulation and that all aspects of it come under the
TBT Agreement.  It seems to us, that in terms of methodology, the whole French measure shouldinitially be examined in relation to the TBT Agreement;  subsequently, it could be examined in
relation to GATT.
219. In the above cases, the question of whether the General Agreement on Trade in Services
(GATS)  and GATT 1994 were mutually exclusive was raised because GATS does not cover the same
subject as GATT.  The Appellate Body decided at that time that the agreements were not mutually
exclusive.  The situation in this case is different.  Indeed, the respective areas of application of the
TBT Agreement and GATT 1994 overlap.  In our reply to question 35 by the Panel, we said that "theTBT Agreement is the most recent and most specific expression of the WTO Members as to what the
interpretation and application of the disciplines under GATT 1994 […] should be in the context of
technical regulations and standards".
121  The two agreements cover the same subjects, the
TBT Agreement being a development of GATT disciplines.  It is therefore difficult to see how in
practice certain specific aspects of the French measure would come under the TBT Agreement whileother aspects would be governed by GATT.  The TBT Agreement is more specific than GATT 1994
in the area of technical regulations.  As the French measure is a "technical regulation" in the meaning
of the TBT Agreement, it would seem to us appropriate first to examine the measure in the light of the
disciplines in that agreement, with particular reference to the GATT disciplines.  This methodological
approach flows from the most recent case law on relations between the WTO Agreements, which
requires that claims should first be examined under a more specific agreement rather than
GATT 1994.
122  Canada maintains that the Panel should first examine all the disputed elements and
aspects of the French measure in the light of the TBT Agreement.
(ii) Reply by the European Communities
220. In general, the question of deciding which WTO Agreement applies to a given measure is a
problem of determining the character of the measure.   In the absence of a specific provision in the
relevant WTO Agreements123, one has to examine essentially the aim and content of the measure in
question.  A measure that has a single and uniform aim and content should fall under one agreement.
Equally, a measure that pursues several distinct or heterogeneous aims can potentially fall under
several, different agreements.  But not every element in a measure attributes a different, multiple aim
to the measure under examination.  Secondary, accessory or ancillary provisions do not necessarily
alter the essential aim of the measure for the purpose of determining its legal character.124  Therefore,
the essential or principal purpose of the measure, as this is objectively expressed in its design,
architecture and structure, determines its character and the applicable agreement.  In defining the
essential or principal objective of a measure, one has to look at the centre of gravity or predominant

122 Indonesia - Certain Measures Affecting the Automobile Industry , Report of the Panel,
paragraph 14.63:  "On the question of whether the allegations should first be examined under Article III:4 ofGATT or Article II of the TRIMs Agreement, we believe that we should begin by examining the claims under
the TRIMs Agreement since that is more specific than Ar ticle III:4 in relation to the claims under consideration.
A similar question arose in the Bananas III  case, in which the Appellate Body examined the relationship
between Article X of GATT and Article 1:3 of the Agreement on Import Licensing and concluded that, since theAgreement on Import Licensing was more specific, it should be applied first."
123 See, for example, Article 1.5 of the TBT Agreement and Article 1:4 of the SPS Agreement.
124 See, by analogy, the findings of the Appellate Body in the Reformulated Gasoline Case , in which
the "substantial relationship" of two positions of the gasoline rule was decided in the light of the overall aim of

Page 61
component of the aim pursued by the measure in qu estion, as this emerges or becomes apparent from
the measure itself.125
221. Therefore, the reply to the question would depend on how significant and independent the
"other elements" of the measure are,  in other words, whether they are capable of attributing a distinct,
different and additional aim to the one principally pursued by the measure in question.  Only in such asituation may some elements of a measure fall un der the provisions of GATT and other elements of
the same measure fall under the provisions of the TBT Agreement.
222. Applying the above principles to the French Decree in question, the Panel should conclude
that it pursues only one, single, uniform aim, that is to ban the use of any kind of asbestos for the
purpose of protecting human health.  As the European Communities have explained at length in their
written and oral submissions, this sole object of the Decree flows from the ordinary meaning of its
terms in their context, the design and structure of the measure and the history of the preparatory work.The essential object and purpose of the Decree is to lay down a general, horizontal ban on the use of
asbestos and asbestos-containing products.  It does not relate to the preparation, adoption, and
application of a technical regulation of any kind, in the sense of the TBT Agreement.  Neither does it
lay down a process and production method for asbest os and asbestos-containing products, simply
because it bans their use.
223. One may wonder whether the limited and temporary exceptions laid down in Article 2 et seq .
are a sufficiently important or independent element as to attribute another, separate and different aim
to the Decree.  As the European Communities have already explained, this is clearly not the case.
Article 2 et seq.  of the Decree state expressly that "exceptionally and on a temporary basis" certain
products may continue to use chrysotile asbestos in order to ensure "an equivalent function" and solong as there exists "no substitute" for chrysotile which can ensure a lower level of risk and guarantee
the same level of safety to users.  This is an exception to the general ban, and exceptions by definition
are to be interpreted narrowly.  Article 2 et seq.  explicitly state that the exception is temporary and
will be phased out when substitute products become technically available.  As the European
Communities have already shown, the practice followed since the adoption of the Decree in 1996confirms the ephemeral nature of these exceptions.
126  Consequently, these exceptions are not an
essential, but rather an ancillary, accessory or subsidiary element of the Decree.  They lay down no
technical regulations or standards in the sense of the TBT Agreement and, therefore, cannot render the
entire Decree subject to the TBT Agreement.  And ev en if we were to assume that the exceptions do
lay down technical regulations (which they do not), at best only those exceptions would fall under the
scope of the TBT Agreement.  But Canada does not claim that those exceptions constitute a violation
of the TBT Agreement.  Therefore, the question of whether some elements of the Decree (in this casethe temporary exceptions) can fall within the TBT Agreement is, from a strict legal point of view,
totally irrelevant to the outcome of this case.
127  
                                                     
125 This is, for example, the way the issue of the relevant legal basis and of the applicable EC treaty
provisions are determined in European Community law:  see, for example, judgement of 11 June 1991,Case C-300/89, Titanium Dioxide [1991] ECR I-2867.  For the problem of characterization in general underinternational law see, for example, J.A. Salmon, Some Observations on Characterisation in Public International
Law, in UN Law/Fundamental Rights, Two Topics in International Law (ed. A. Cassesse, 1979), page 3 et seq.
126 The EC notes, that in fact, the number of exceptions has fallen rapidly since the adoption of the
French Decree prohibiting all kinds of asbestos. Thus, in 1997, 87 enterprises used 1,200 tonnes of asbestosunder all the permitted exceptions.  In 1998, only 63 enterprises used 200 tonnes, 40 per cent of which was usedby a single enterprise to produce "waterproof seals" (Latty-Soffa seal).  In 1999, the number of enterprises fell to25 with a volume of only 50 tonnes, 80 per cent of which was used by a single enterprise to produce chlorine(chloride).
127 According to the EC, this propos ition finds implicit support in the decision of the Appellate Body in
the Reformulated Gasoline  case, where it discussed the term "measures" for the purpose of deciding whether theWT/DS135/R/Add.1

Question 3:
(a) In assessing the conformity of a measure with Article XX of GATT, what would be the
relevance of any practical difficulties encountered by a country in implementing a measure, in
assessing whether the measure was reasonably capable of achieving the objectives of its healthpolicy?
(b) In assessing the conformity of a measure with Article 2.2 of the TBT Agreement, what
would be the relevance of any difficulties in the practical implementation of a measure in
evaluating whether it was less trade-restrictive than the measure in place?
(i) Reply by Canada
Reply 3(a)
224. Canada is of the opinion that any claims of practical difficulties inherent in the
implementation of a measure are not a factor to which any weight should be given in assessing thereasonable availability of a measure as a less trade-restrictive alternative.  In considering a measure in
the light of the criteria of necessity in Article XX of GATT, the practical difficulties of implementing
an alternative to the measure under dispute – if such exist – do not detract from the alternative or
exclude it as a less trade-restrictive alternative.  In the context of the test
 of necessity, assessing the
legality of a measure in the light of so-called practical difficulties encountered in implementing itwould be to reward laxity in implementing a measure and compensate administrations for their
inefficiencies.  It would then become easy for Members to evade the GATT disciplines, because they
would simply have to allege practical difficulties in  implementation – i.e. the inefficiency of their own
administration – to exclude a less trade-restrictive alternative measure, and thus escape the GATT
disciplines.  In the light of the application of the test of necessity in Article XX of GATT, a Memberthat generally devotes significant resources to ov ercoming practical difficulties in implementing a
regulation and which can pride itself on the efficient administration of its regulatory framework would
be penalized vis-à-vis a Member who decided to deploy few resources to implement regulations or
which proved to be lax in that regard.  To assess, in the context of analysing Article XX of GATT,
whether an alternative measure is reasonably available in the light of the existence or otherwise of
practical difficulties in implementing it would be a dangerous precedent which would weaken the test
of necessity, produce Kafkaesque results and lead to pernicious effects on a systemic scale.  In thisrespect, the decisions of the Panel and the Appellate Body in the case of United States – Standards for
Reformulated and Conventional Gasoline
128 support Canada's position.  In that case, Venezuela and
Brazil complained about the discriminatory nature of the American standards on gasoline, which were
aimed at environmental protection.  The United States unsuccessfully used as a defence the general
exceptions in Article XX of GATT.  It is clear from both the decision of the Panel and of theAppellate Body that under the regime of the test of necessity in Article XX of GATT, practical
difficulties in the implementation of an alternative measure do not exclude that measure as a less
trade-restrictive measure.
225. In the case of United States – Standards for Reformulated and Conventional Gasoline , the
United States pleaded, as in this case do the European Communities, that the alternative measure
                                                                                                                                                                    
entire Gasoline Rule or only the baseline establishment rules fell within the scope of Article XX(g).  It explained
that " The Panel report did not purport to find the Gasoline Rule itself as a whole, or any part thereof other than
the baseline establishment rules, to be  inconsistent with Article III.4;  ac cordingly, there was no need at all to
examine whether the whole of the Gasoline Rule or any of its other rules, was saved or justified byArticle XX(g)".  See AB-1996-1, p. 12.

Panel), adopted 20 May 1996.WT/DS135/R/Add.1
Page 63
invoked – the establishment of individual baselines for foreign refiners – was not reasonably available
and could not be upheld because it presented practical difficulties in implementation.  In support of
their argument under Article XX of GATT, the United States submitted to the Panel that the
application of an individual baseline to foreign refiners was not feasible for three reasons:  (i) the
impossibility of determining the refinery of origin of each imported cargo;  (ii) the temptation forexporters and importers to "manipulate" the system;  (iii) the difficulty for the United States of
assuring compliance by foreign refineries with the Gasoline rule, since, to be effective, that, it was
supposed, would require penal and civil sanctions.
129  In its communication to the Appellate Body, the
United States reiterated its positions:130
"The impracticability of verification and enforcement of foreign refinery baselines in this instance
shows that the 'discrimination' is based on serious, not arbitrary or unjustifiable concerns stemming
from different conditions between enforcement of its laws in the United States and abroad. (Footnoteomitted)."
226. The Panel rejected the American argument based on the practical difficulties of implementing
individual baselines for foreign refiners.131  The Appellate Body, for its part, although its decision
mainly related to Article XX(g) of GATT and the introductory paragraph of Article XX of GATT,
cited and approved the reasoning of the Panel concerning the incidence of practical difficulties inimplementing individual baselines for foreign refiners on the application of the test of necessity in
Article XX.  Thus, the Appellate Body states:
132
"The United States stated that verification and enforcement of the gasoline rules requirements for
imported gasoline are 'much easier when the statutory baseline is used' and that there would be 'a
dramatic difference' in the burden of administering requirements for imported gasoline if individual
baselines were allowed.
While the anticipated difficulties concerning verification and subsequent enforcement are doubtless
real to some degree, the Panel viewed them as insufficient to justify the denial to foreign refiners ofindividual baselines permitted to domestic refiners. (Footnotes omitted)".
227. It is interesting to note that the Appellate Body, like the Panel, recognizes that the practical
difficulties of implementing the alternative measure are indeed real.  That does not prevent them from
considering it as a measure reasonably available to achieve the environmental objectives pursued by
the United States.  The Appellate Body thus confirms the reasoning and conclusions of the Panel
whereby the existence of practical difficulties in implementing an alternative measure do not
disqualify it as a less trade-restrictive alternative, under the test of necessity.133  F o r  t h e  A p p e l l a t e
Body and the Panel, an alternative measure fulfils the test of necessity even if the measure preferred
by the defending party is "much easier" to implemen t than the alternative measure, and that there is
"dramatic difference" in the administrative burden between the measure under consideration and the
alternative.  For the Appellate Body and the Panel, the alternative measure will be excluded only if it
is clearly impossible to implement it.134  The decision of the Appellate Body and the Panel in
United States – Standards for Reformulated and Conventional Gasoline  clarify the principles outlined
by the Panel in United States – Section 337 of the Tariff Act of 1930.135  The decisions of the

Appellate Body and the Panel in United States – Standards for Reformulated and Conventional

Tariff Act of 1930.   It should be recalled that in that case, the Panel had rejected the basic American
claims that the disputed provision met the test of necessity under Article XX(d) of GATT 1947
"because of difficulties with service of process on and enforcement of judgement against foreignmanufacturers."

228. Concerning the dispute between Canada and the European Communities regarding measures
concerning asbestos and products containing asbestos, Canada's position in relation to the problem of
practical difficulties in implementation hinges on two points.  Firstly, we maintain that to achieve its
objective of protecting human health, the French Government had available to it an alternative less
trade-restrictive measure.  Instead of acting in haste and under pressure from its public opinion, it
could have introduced a regulatory framework under which prohibitions and authorizations ofproducts containing asbestos would have been established in a rational manner on the basis of two
guiding principles:  (i) assessment of the risks on a product-by-product and use-by-use basis;
(ii) analysis of the feasibility and effectiveness of controlled use for each product.  Canada maintains
that such a regulatory framework would not be diff icult to implement in practice and that it would not
be impossible to introduce.  In that light, Canada maintains that there is a less trade-restrictive and
reasonably available alternative measure to achieve the objectives pursued by France.  Secondly,
Canada maintains that in any case and as a general rule, any practical difficulties in implementing a
measure are not a factor to be considered in assessing whether the measure is reasonably available and
applying the test of necessity under Article XX of GATT, unless it is clearly established that these
practical difficulties make implementation absolutely impossible.  Canada's position relies partly onthe cases of United States – Standards for Reformulated and Conventional Gasoline and United States
– Section 337 of the Tariff Act of 1930  and, secondly, on the conviction that taking account of the
practical difficulties of implementation in applying the test of necessity would weaken the GATT
disciplines by indirectly rewarding laxity and inefficiency.

229. The European Communities and Canada agree that:  (i) Article 2.2 of the TBT Agreement
contains a test of necessity;  (ii) the analysis involved  in this test of necessity is similar to that relating
to the test of necessity in Article XX:(b) of GATT.  Consequently, our reply to question 3(a) on
Article XX of GATT applies equally to Article 2.2 of the TBT Agreement.  In particular, the
principles formulated by the Panel and the Appellate Body in United States – Standards for
Reformulated and Conventional Gasoline cited in Canada's reply to question 3(a) are wholly
applicable in the context of the test of necessity in Article 2.2 of the TBT Agreement.
(ii) Reply by the European Communities
230. All the Panel and Appellate Body reports that have examined so far the test of "necessity"
under Article XX:(b) of GATT have come to the conclusion that a restrictive measure taken by aMember is not necessary if an alternative measure, which that Member could reasonably be expected
to employ and which is not inconsistent with other GATT provisions, is available to it.
137  A careful
look at the rationale of the Panels demonstrates that the alternative measure must be:  (i) effectively
available to the Member in question;  (ii) reasonab ly expected to be employed;  (iii) not inconsistent
or less inconsistent  with other GATT provisions;  (iv) capable of ensuring the Member's desired level
of health protection.  Thus, in the Section 337  report the Panel held that " neither Article III:4 nor
Article XX:(d) puts obligations on contracting part ies specifying the level of protection that they
                                                     
136 Report of the Panel, paragraph 5.30.
137 See, e.g, Section 337  Panel report, BISD 36S/345, para. 5.26;  Thai Cigarettes  Panel report,
BISD 37S/200, paragraph 75;  Reformulated Gasoline  Panel report, WT/DS2/R, paragraph 6.22-6.28.WT/DS135/R/Add.1
Page 65
should accord to patents or the effectiveness of procedures to enforce such protection".138  
Consequently, the Panel held that:
• A different scheme for imports alleged to infringe process patents established by
Section 337  was not necessary because the alternative of granting jurisdiction to civil
courts over imports of products manufactured abroad was available and actually
applied   both in third countries and by the United States (paragraph 5.28);
• Presidential review in order to secure compliance with United States patent
legislation and the difficulties with service of process on and enforcement of
judgments against foreign manufacturers was not objectively necessary mainly
because no equivalent requirements were applicable involving products of domestic
origin (paragraphs 5.29 and 5.30);
• a system for the enforcement of in rem  orders was necessary because it would
"generally be more difficult" and "seldom feasible" to secure enforcement of the
rulings of a court in the country of production.  The alternative measure (i.e. an action
in personam )  was judged to be not "an adequate substitute … in all cases" because,
inter alia, importers might be "very numerous and not easily"  brought into a single
judicial proceeding (paragraph 5.31).  For these reasons the panel concluded that
there could be "an objective need" in terms of Article XX:(d) to apply limited in rem
exclusion orders to imported products only.  On this point, therefore, the lack of an
alternative feasible and equally efficient measure played an important role in deciding
"necessity";
• exclusion orders which were automatically enforced by the United States customs
service were also found to be necessary because such enforcement at the border was
considered to be "a means necessary to render such orders effective"
(paragraph 5.33).
231. In the Thai Cigarette case the Panel found that the reasons advanced by Thailand to justify
the import restrictions at issue were to protect the public from harmful ingredients in importedcigarettes and to reduce the consumption of cigarettes.  So the measures were intended to ensure the
quality and reduce the quantity of cigarettes sold in Thailand.  But the Panel found that the Thai
concerns about the quality of cigarettes consumed could be met "with strict, non-discriminatory
labelling and ingredient disclosure regulations … coupled with a ban on unhealthy substances"
(paragraph 77).  As regards the Thai concerns about the quantity of cigarettes consumed, the Panelnoted the view expressed by WHO that demand for cigarettes, in particular by the young, was
influenced by cigarette advertisements and that bans on advertisements could therefore curb demand,
and that Thailand could also restrict the supply of  cigarettes by maintaining governmental monopolies
on the importation and domestic sale of products.  Consequently, the Panel concluded that Thailand's
practice of permitting the sale of domestic cigarettes while not permitting the importation of foreigncigarettes was not necessary within the meaning of Article XX:(b) of GATT (paragraphs 78-81) .
232. In the Reformulated Gasoline  case, the Panel examined carefully all the arguments of the
United States in order to determine whether it was practically feasible to assign to foreign producers
an individual baseline so as to enable imported gasoline to benefit from the same favourable sales
conditions under the Gasoline Rule  as domestic gasoline.  The Panel held that preventing imported
gasoline from benefiting from as favourable conditions of sale as domestic gasoline was not necessary
to achieve the stated goals of the Gasoline Rule , that is to reduce air pollution resulting from the
consumption of gasoline.  The reasons on which the Panel based its findings were that the
                                                     
138 Panel report on Article 337, supra,  paragraph 6.1.WT/DS135/R/Add.1
Page 66
United States had not satisfied its burden of proving that it was "not feasible" to establish individual
baselines for foreign producers, or that there were  any reasons that "precluded the effective use" of
individual baselines, or that there were "any particular difficulty" sufficient to warrant the method of
establishing baselines used by the United States (paragraphs. 6.23-6.26).  It also found the that United
States did not meet its burden of showing whether the "gaming" concern "would actually occur" , and
that slightly stricter overall requirements on non-degradation of gasoline could not be implemented by
the United States "at any time" (paragraph 6.27) .  The Panel also found that "the imposition of
penalties" on importers was "an effective enforcement mechanism" used by the United States in other
settings, because the United States had not demonstrated that the data available from foreign refiners
was "inherently less susceptible" to established techniques of checking, verification, assessment and
enforcement than data for other trade in goods subject to United States regulation (paragraph 6.28).139
233. In consequence, in order to decide whether an alternative measure is reasonably available,
panels have looked at the specific facts of each individual case.  In all the three Panel Reports
mentioned above, the Panels identified specific alternative measures that were objective, effective and
constantly available to the Member applying the in consistent measure in question.  They also found
that theoretical or potential measures, i.e. measures that were not real, feasible and as effective in
practice as the measure applied, were not enough.  The Panels and the Appellate Body appear, almostinvariably, to have judged a measure not necessary, simply on the grounds that the same or an
equivalent measure was not applied to products of domestic origin.  They also found that the effective
alternative measure should be clearly capable of achieving the pursued legitimate objective
(i.e. achieve the desired level of health protection).  It follows that objective difficulties in the
effective application of the possible alternative measure that risk compromising the desired level ofprotection render the measure in question not reasonably available and one not reasonably expected to
be employed by the Member.
234. To reply specifically to the Panel's question, objective difficulties in the practical application
of a measure play a crucial and determining role in deciding whether that measure is a reasonably
available alternative measure to the one actually applied by a Member.  As the EuropeanCommunities have already explained in their written and oral submissions, the possible difficulties in
the practical application of a measure may be of a wide and diverse nature, e.g. practical, technical,
legal, economic, scientific or a combination of two or more of these reasons.  The European
Communities have already identified in its submissions a large number of such objective difficulties.
The scientific experts have also confirmed those difficulties, in writing and orally.  The outcome of
their evaluation was that all these difficulties render "controlled use" not feasible or practicable.  In
deciding whether an alternative measure is reasonably available, Panels have to examine whether it isobjectively available, feasible, effective and proportional to the pursued legitimate objective of
protecting human health.  In so deciding, one should always keep in mind that Article XX:(b) of
GATT clearly allows contracting parties to give pr iority to human health over trade liberalization.
140
Therefore, the result in this particular case is that so called "controlled use" does not achieve the level
of health protection desired by France.
235. The same applies in the context of Article 2.2 of the TBT Agreement.  Possible objective
difficulties in the practical application of a measure play an equally crucial and determining role in
deciding whether that measure is less restrictive on trade than the one actually applied.  The text of
Article 2.2 is clearer on this point because it provides that when applying the necessity test ("creating
unnecessary obstacles to international trade" and "more trade-restrictive than necessary"), panelsshould take into account "the risks that non-fulfilment of the legitimate objective would create".  This
clarification imparts meaning to the concept of necessity and indicates the nature of the measure under
examination, because the mere existence of a possible alternative measure will not render the measure
                                                     
139 The findings of the Panel on these points were confirmed on appeal, pages 29-30.
140 See, for example, the Panel Report in Thai Cigarettes , paragraph 73.WT/DS135/R/Add.1
Page 67
actually applied more trade-restrictive if the former cannot achieve the desired level of health
protection.
236. Under Article 2.2 of the TBT Agreement, as under Article XX:(b) of GATT, the possible
objective difficulties in the practical application of a measure may be of a wide and diverse nature,
e.g. practical, technical, legal, economic, scientific or a combination of two or more of these reasons.Article 2.2, in fine , provides some examples, inter alia , of the elements that Members (and Panels)
may take into account in deciding the less trade-restrictive nature of the measure actually applied and
whether an alternative measure, which can fulfil the pursued legitimate objective, is reasonably
available to the Member in question.
237. Without going as far as Article 5 of the SPS Agreement, Article 2.2 of the TBT Agreement
nevertheless goes textually further than Article XX:(b) of GATT, because it explicitly links the
necessity test with an assessment of the risks to human health and the design and structure of themeasure under examination.  Moreover, by analogy, Article 5.6 of the SPS Agreement and the notes
thereto clarify that "a measure is not more trade-restrictive than required unless there is another
measure, reasonably available taking into account technical and economic feasibility, that achieves
the appropriate level of sanitary or phytosanitary protection and is significantly less restrictive on
trade".  Although the principles and provisions of the SPS Agreement are not applicable in the contextof GATT and the TBT Agreement, the underlying philosophy of these provisions may nevertheless
assist us in interpreting Article XX:(b) of GATT and Article 2.2 of the TBT Agreement as regards the
need, for the purpose of judging the necessity of a measure, to take into account the risks to human
health arising from difficulties in the practical application of a measure.
238. Applying the above principles to the facts of the present case, it is clear that a number of
practical, technical, legal, economic and scientific reasons do exist such that there is no alternative
measure reasonably available to France to the total ban on all kinds of asbestos. The European
Communities have discharged their burden of proof, because the reports of numerous competent
international institutions (e.g. the WHO Environmental Health Criteria Report Number 203 and the
IARC Monographs) clearly confirm the findings of the INSERM Report, and the scientific expertschosen by the Panel fully endorsed INSERM's findings and the arguments of the European
Communities.  In the case of a substance that has been classified officially as a proven human
carcinogen and for which it is impossible to establish scientifically an exposure threshold and when
there is a vast category of persons that may be exposed to it because of the diverse nature of their
activities, difficulties in the practical application of so-called "controlled use" make it clearly not a
reasonable alternative measure for France, in the sense explained above, to the total ban on any kind
of asbestos.  Canada's belated attempt to limit the scope of this dispute to high densitychrysotile-containing cement products flies in the face of the available scientific evidence.
141  F o r
example, the WHO Report Number 203 states:
"Some asbestos-containing products pose particular concern and chrysotile use in those circumstances
is not recommended.  These uses include friable products with high exposure potential.  Construction
materials are of particular concern for several reas ons.  The construction industry work force is large
and measures to control asbestos are difficult to institute.  In-place building materials may also pose
risk control to those doing alternations, maintenance and demolition.  Minerals in place have the
potential to deteriorate and create exposures."142
                                                     
141 The European Communities note that Canada has never claimed in its request for consultations or in
its request for the establishment of the Panel that the scope of this dispute is about high densitychrysotile-containing cement products.  Also, the terms of reference of the Panel do not contain such aprovision.  Furthermore, Canada has been exporting only chrysotile asbestos as a raw material, not high density
chrysotile-containing cement products.
142 Point 3 of the conclusions and recommendations, WHO Report Number 203.WT/DS135/R/Add.1
Page 68
239. These WHO findings have been fully endorsed by all four scientific experts chosen by the
Panel.  The available evidence and the experts consulted by the Panel concur with the
European Communities in saying that so-called "controlled use" is not really feasible or practicable.
Moreover, it is important to emphasize that the available evidence and the experts also confirm that
even if "controlled use" were feasible in practice, in those cases where it might be applicable it is stillinherently not effective because it cannot eliminate all risks.  Canada has never argued that there was
"no risk" at low levels of exposure, but merely that it becomes "undetectable".  The available evidence
and the experts consulted by the Panel (including one of the experts of Canada, Dr. McDonald)
confirmed during the meeting with the experts on 17 January that the linear model is appropriate and
that there is no scientifically established threshold of exposure below which there is no risk.  The
experts also agree with the European Communities that to apply "controlled use" would entail very
serious health risks as well as technical, administrative and economic costs to France.  They alsoagree that the application of administrative controls and fines do not act as a real deterrent, because
too many and serious violations still occur very frequently in countries which do not prohibit asbestos
completely but simply try to control its use.  Theref ore, the risks associated with asbestos in place and
the measures taken to deal with them are not relevant in deciding whether the "controlled use"
proposed by Canada is a reasonable alternative measure to the total prohibition of asbestos.  In theabsence of any discrimination in the application of the total ban, the legitimate health objective
pursued by France by far outweighs any economic benefits to Canada.  Once again, the
European Communities would like to emphasize that under Article XX(b) of GATT a WTO Member
has the right to determine its level of protection as it considers appropriate.  The European
Communities would also like to emphasize that under Article 2.2 of the TBT Agreement a WTOMember is entitled to take measures "taking account of the risks non-fulfilment would create", and
that the ultimate risk in the case of asbestos is death.  The European Communities have established in
their submissions and oral statements that lung cancers, mesotheliomas and other asbestos-related
diseases occur despite the appropriate use of adequate protection.  Hence, the European Communities'
objective to eliminate the risks induced by asbestos cannot be met by so-called "controlled use", evenif it were feasible in practice.
Question 4:  Can Canada and the European Communities expand on their arguments
concerning the implementation of measures relati ng to the use of chrysotile asbestos and its
various applications (i) in Canada;  (ii) in France prior to the prohibition imposed by the
Decree.  In particular, for France and Canada respectively, are there any data on the
effectiveness of inspection and surveillance me asures designed to ensure compliance with the
regulations concerned, in particular in the various activities relating to the building industry?If yes, what do they show?
(i) Reply by Canada
240. Controlled use in Canada involves strict control of average concentrations of asbestos fibres
in the workplace, the prohibition of friable products containing asbestos and the adoption of measures
to ensure the health and safety of workers exposed to friable asbestos in place and chrysotile in high
density products.  Thus, controlled use consists of regulation, workplace inspections (especially
construction sites), prevention through information and training and registration and monitoring the
health of workers exposed to asbestos.  In Canada, these measures normally come under theresponsibility of the provinces and as the only Canadian asbestos mines are in Quebec and that is
where the bulk of the chrysotile industry is located, our analysis focused on the situation in Quebec.WT/DS135/R/Add.1

Existing legislation and regulations
241. The Quebec system of health and safety at work is the result of a broad consensus;  it is the
social contract which binds over two million workers and their employers in relation to occupational
health and safety.  In order to establish the rights and obligations of each, and to put in place themeans to exercise them, Quebec passed the Occupational Health and Safety Act  (LSST)
143, which
covers prevention and the Occupational Accidents and Diseases Act  (LATMP)144, covering workers
compensation and rehabilitation.  This legislation makes employers and workers responsible for
health and safety in their workplace.  The Occupational Health and Safety Commission (CSST) is
responsible for enforcing it.  There are several implementing regulations under this legislation
concerning the whole raft of pollutants present in the workplace.  In the case of the LSST, we would
draw attention in particular to the Regulation on the Quality of the Workplace  (Regulations)145 and the
Code of Safety for Construction Works (the Code) .146  In 1989, the Quebec Government amended all
the legislation and regulations covering the workplace in order to take account of the provisions of
Convention 162 of the International Labour Organization (ILO) concerning Safety in the Use of
Asbestos.147  The Regulations and the Code govern workin g conditions in chrysotile mines, in plants
manufacturing asbestos products, in enterprises specializing in maintenance of buildings and removalof asbestos flockings in Quebec and in the construction sector.  Among other things, Section 3 of the
Regulations governs air quality by prescribing the applicable standards, protective equipment and
control measures for some 600 air pollutants in the workplace, including chrysotile asbestos.
Annex A of the Regulations sets out the acceptable levels of exposure to dust.  The weighted average
exposure level for chrysotile asbestos is 1 f/ml.  Article 5 of the Regulations provides that anyestablishment whose operations may lead to the emission of dust in the workplace must be operated
so as to ensure that the concentration of dust, in the workers' respiratory area, does not exceed the
levels laid down in the regulations for any indicated period of time.  Article 5 of the Regulations also
provides that the use of crocidolite, amosite or a product containing either of these substances, is
prohibited unless there is no reasonable and practicably feasible alternative.
148  Subsection 3.23 of the
Code applies to any construction site where work is carried out that may lead to the emission of
asbestos dust.
242. The Code prohibits the spraying of a surface with a mixture of friable materials containing
asbestos and the installation of friable insulation materials containing asbestos.  In order to ensure the
application of adequate protection measures, construction sites are divided into three categories:
(1) low risk;  (2) moderate risk;  and (3) high risk.  Sites where low risk work is carried out include
installation, handling or removal of manufactured articles containing asbestos, provided that they areand remain in a non-friable condition, such as an asbestos-cement product.  They also include sawing,
cutting, machining and drilling of an asbestos-cem ent product with manual tools or electric tools
equipped with a dust extraction system with a high performance filter.  The Code provides that on a
site where low risk works are carried out, such as sawing, cutting, machining, drilling of an asbestos-
cement product with manual tools or electric tools equipped with a dust extraction system withhigh-performance filter, the employer must ensure that any worker present in the working area wears
a breathing mask.  The wearing of breathing masks is, however, not required for work such as
installation, handling or removal of an asbestos-cement product.  Sites where high risk work is carried
out, include, for example, handling or removal of friable materials containing asbestos, by spraying a
binding agent, and utilization of electric tools, not equipped with a dust extraction system with a high

performance filter, for grinding, cutting, drilling or sanding an asbestos-cement product.  On sites
where high-risk work is carried out on friable materials in place, the employer must comply with
much stricter requirements.  These include wearing breathing apparatus of the semi or full mask type,
sampling of the concentration of respirable asbestos fibres in the air in the working area at least once a
shift, provision of protecting clothing to worker s, providing workers with lockers for work clothing
and personal clothing, provision of a shower room , isolation of the working area and the locker room
for work clothes from the remainder of the building by a sealed partition equipped with an extraction
ventilation system.  The Code also provides that be fore work is commenced that might result in the
release of asbestos dust, the employer must tr ain and inform workers on the risks, methods of
prevention and safe working methods.  The training and information programme must include the
employers general obligations, the effects of asbestos on health, the applicable standards and the
sampling to be carried out, the workers rights and obligations, personal and collective protectionmeasures and equipment, tasks to be carried out and the equipment or tools to be used, safe working
methods and procedures, and methods of prevention and control.
Role of the Occupational Health and Safety Commission (CSST)
243. The Occupational Health and Safety Commission ( Commission de la Santé et de la Sécurité
au Travail ) fulfils its administrative functions in a variety of ways.  It is concerned, inter alia , to
prevent occupational injuries while at the same time playing the role of public guarantor for
employers and workers alike.  In addition, the CSST provides workers and employers with the
services to which they are entitled.  In the case of prevention it is involved in promoting occupational
health and safety, assistance to workers and employers in their efforts to improve their working
environment and eliminate hazards, and workplace inspections.  The role of the CSST is mainlyfocused on prevention, specifically through the comprehensive analysis of the causes of occupational
accidents and diseases.  Consequently, when it investigates a work place, all the chemical and
physical pollutants, including chrysotile asbestos, and all working constraints are taken into account.
The CSST requires the employer to implement a prevention programme.  The prevention programme
also includes a health programme, which involves monitoring workers' health for the prevention andearly detection of any medical condition caused or aggravated by work.
Implementation of controlled use
244. In workplaces where, inter alia , chrysotile asbestos is found, a variety of actions for
implementing the legislation and regulations under ILO Convention 162 has been carried out in recent
years.  More specifically, we present data for which we have performance indicators relating to
inspection, health services, training and information for workers in a variety of environments, inparticular, the construction industry.
245. Inspection:  When an inspector investigates a construction site or an industrial establishment,
he opens an investigation file and visits the work site on one or more occasions.  During his visit, he
may find various breaches of the regulations concerning chemical and physical pollutants and other
provisions on occupational health and safety.  He may take a number of actions, including closing thesite which means halting the work until the appropriate remedial measures are put in place.  The
record of activities of the inspection service of the CSST in the construction sector show that in
Quebec in 1999, 14,928 inspections were carried out in all areas of economic activity, including
5,171 inspections of construction sites.  These inspections gave rise to 234 occupational health and
safety proceedings relating to asbestos.  The main reasons for proceedings were the following:  lack oflockers or showers, failure to isolate the working area and the locker room from the remainder of the
building by means of a sealed partition equippe d with a dust extraction and ventilation system
(37 cases)
149, failure to dampen friable materials containing asbestos during removal works and failure
                                                     
149 Code of Safety for Construction Works, Article 3.23.16.WT/DS135/R/Add.1
Page 71
to use a dust extraction system equipped with a high-performance filter to remove debris containing
asbestos (28 cases)150, failure to provide disposable protective clothing or reusable protective clothing
(27 cases)151, and failure to take daily samples of the concentration of respirable asbestos fibres in the
air in the working area (5 cases).152  Eighteen sites were closed for non-compliance with standards.
We should emphasize that in 1999, all asbestos-relat ed occupational health and safety proceedings on
building sites concerned exclusively friable asbestos products and not asbestos-cement products.
246. Training and information:  The various training  sessions developed and delivered by partner
bodies in the occupational health and safety network are targeted at several types of client and, for
that reason, the content and length varies.  In 1997, the CSST took stock of its continuous training
programmes for its inspectors and that led to the development of a specific training module on
asbestos.  As a result, in 1998 and 1999, the CSST delivered two types of training on chrysotile
asbestos, a three-day course aimed at inspectors in the construction sector and specialists in the healthnetwork, and a two-day course for inspectors in industrial establishments.  So far, the CSST has
delivered eight two-day courses in which 77 inspectors participated.  The three-day training sessions
provided training for 80 construction sector inspectors and some 30 people from the health network.
At the beginning of June 1999, in collaboration with its partners, the CSST launched the programme
for the prevention of occupational diseases related to asbestos exposure.  Aimed this time at workersand employers, the programme focuses on prevention measures to be taken not only on renovation
and demolition sites, but also in repair and maintenance work.  The objectives are to inform about
appropriate working methods and suitable protective equipment for all work, which may give rise to
the release of asbestos dust and ensure that they are used.
247. For its part, the joint sectoral association for occupational health and safety in the construction
sector (ASP-Construction) has, since 1992, been offering a four-hour training course for construction
workers.  The course on asbestos safety meets the requirements on Article 3.23.7 of the Code.  The
participants in this course are mainly general labour, insulation appliers, pipe fitters, electricians, fire
protection engineers, demolition workers etc..  The following table shows the annual distribution of
data for this course provided by the ASP-Construction Consultants:

250. Health services:  In the Montreal region, in September 1998, there were 23 establishments
using chrysotile in their processes or operating plants which could cause occasional exposure of
workers to chrysotile:

251. The preventative measures in place in these establishments include regular medical
supervision, environmental monitoring, respiratory protection and information on health risks.  All of
these actions are encompassed in each establishment's prevention programme.
Controlled use in France and the United States
252. We note that the French system for registering asbestos in place does not require the inclusion
of chrysotile cement products.153  It appears that France, in its approach to management of the risks
related to the use of asbestos, is not concerned with chrysotile cement products which do not present
any detectable risk to health.  The INSERM data are quite clear about the efficiency of controlled use
in the French manufacturing industry.  Of 2,480 people working in the asbestos processing sector in
France in 1994, only two (0.1 per cent of workers) we re exposed to concentrations of over 0.6 f/ml.154
Consequently, it is difficult to talk of the impossibility of controlled use in the processing industry
when compliance with exposure standards throughout the territory of France required only one
intervention concerning two workers.  The American experience also shows the effectiveness and
practicability of implementing a controlled use policy.  As pointed out by Canada at the second
substantive meeting, the OSHA in the United States only recorded 16 cases of exceeding themaximum exposure levels of 0.1 f/ml throughout America in the year 1998-1999.
155  It should be
noted, furthermore, that those exposures were related to friable materials, whose use is proscribed
under the principles of controlled use as set out in international standards and by Canada.  Yet again,
hard to speak of ineffectiveness and the impossibility of controlled use.
Conclusion
253. All the above data shows that here have been many and varied preventative activities relating
to chrysotile asbestos used in various working environments, including the construction sector.  They
effectively take account of the various provisions contained in the legislation and regulations.  It is
difficult in the case of asbestos to use medical performance indicators because of the latent period ofthe various pathologies related to exposure to chrysotile.  But all these preventative measures make it
possible to monitor exposure and to react in cases where limits are exceeded as the result of an
incident, of whatever nature, in the working environment.
(ii) Reply by the European Communities
254. In France, the implementation of measures relating to the use of chrysotile asbestos and its
various applications was completed in several stages, starting from the date when the carcinogenicnature of asbestos was recognized by the IARC (International Agency for Research on Cancer), in
1977.  The first phase, covering the 1970s, was centred on the production sector, in the course of
which France: (i)  laid down specific rules for the use of asbestos in the manufacturing sector and
transformation of asbestos-based products;  (ii) re stricted its use with a view to protecting the
population.  A second phase, covering the period of the 1980s and the first half of the 1990s centredon restrictions on use, during which the European directives came in:  (i) strengthening workers'
protection in the manufacturing and transformation sectors;  (ii) setting down rules for protection in
the case of removal of asbestos;  (iii) progressively eliminating the most dangerous varieties of
asbestos;  (iv) prohibiting the most dangerous uses;  (v) restricting the use of asbestos in general,
including the use of chrysotile.  A third phase, from 1995 onwards, is centred on the repair andmaintenance sectors, in the course of which France is concerned to:  (i) take into account the risks

faced by repair and maintenance workers;  (ii) strengthen workers' protection on sites where asbestos
is removed and in certain residual asbestos processing centres;  (iii) strengthen protection of the
public.
First phase (1970s)
255. Following the recognition by the IARC, in 1977, that asbestos was carcinogenic, the French
authorities issued specific regulations in order to ensure protection of workers against asbestos-related
risks (Decree No. 77-949 of 17 August 1977 on Specific Hygiene Measures Applicable in
Establishments where the Workforce is Exposed to the Action of Asbestos Dust, hereinafter "the
1977 Decree")156.  The provisions of that Decree supplemented the general measures on protection of
workers and sanitary conditions in occupational premises and general rules of hygiene applicable to
all places of work.  During the same period, asbestos flockings were prohibited in buildings (DecreeNo. 78-394 of 20 March 1978 on Prohibition of Flocking s in all Buildings).  The overall provisions of
the 1977 Decree imposed constraints on employers both in terms of collective protection of workers
(for example:  encasing of industrial systems and devices, humidification, dust extraction and
ventilation of premises, compulsory monthly or quarterly removal of dust, maintenance of common
protection equipment), and individual protection of workers (in particular, free provision of breathing
apparatus).  These provisions applied to all occupational activities involved in handling asbestos or
products containing asbestos and compliance was monitored by labour inspectors along with all other
measures relating to protection of health in the workplace.
Second phase:  the 1980s and the period 1990-1995
256. During the second phase, French regulations developed in line with the provisions of the new
European directives on asbestos.  This development was also in step with progress in scientific
knowledge, and international recommendations (in particular, ILO Convention No. 162 concerning
Safety in the Use of Asbestos.157  In particular, the 1977 Decree was amended twice in order to
translate the relevant European directives into French domestic law:
• The first modification of the 1977 Decree, by Decree 87-232 of 27 March 1987 was
to incorporate the provisions of European Directive 83/477/EEC of19 September 1983, which set the following limits for occupational exposure:
0.5 fibre/cm
3 measured over eight hours for crocidolite, and 1 fibre/cm3 for all other
varieties of asbestos, including chrysotile.
• Second amendment of the 1977 Decree, by Decree 92-634 of 6 July 1992, to
incorporate the provisions of European Directive 91/382/EEC of 25 June 1991, whichlowered the limits of occupational exposure to 0.6 fibre/cm
3 for chrysotile, and
0.3 fibre/cm3 for all other varieties of asbestos.  The European directive also
introduced provisions for protection of workers and the environment specific to sites
of removal of asbestos.
257. Parallel to the translation of the above-mentioned directives into French domestic law, the
French authorities adopted measures to restrict sales which progressively prohibited the use of
crocidolite, then all varieties of amphiboles.  The use of chrysotile was also restricted:  the use of
                                                     
156 This Regulation was repealed by Decree No. 96-98 of 7 February 1996 on protection of workers
against risks related to the inhalation of asbestos dust, cf page 62 (Article 33) of the collection of Frenchregulatory texts on asbestos, in Recueil des textes français dans le domaine de l'amiante , Official Journals,
Ministry of Employment and Solidarity, 1998.
157 International Labour Organization, Convention concerning Safety in the Use of Asbestos,
(Convention 162), adopted 24 June 1986.WT/DS135/R/Add.1
Page 75
chrysotile asbestos was prohibited in the manufacture of certain products such as toys, smokers
articles, paint and varnishes, liquid filters, mortars, plaster, mastics, sizes, low-density insulating or
soundproofing materials, bituminous roofing felt, and textiles susceptible of releasing fibres
(Decree 88-466 of 28 April 1988 on Products Containing Asbestos).158  In any case, since the
beginning of the 1990s, the risks for users of products  containing asbestos were clearly emerging from
the cumulative data.  A database, called "EVALUTIL" was set up to evaluate exposure to asbestos
among users of products containing asbestos.  This database showed up the very high level of
exposure of certain construction workers in the course of operations ("exposure peaks" during
operations such as cutting asbestos cladding containing 5 per cent chrysotile, cutting up fireproof
doors coated in asbestos, for example).  Following the publication of certain studies159 which showed
the increase in the number of mesotheliomas and the significant risk to the population of workers in
the maintenance and repair sectors, the French authorities convened an expert group in 1994.  Thedeliberations of these experts highlighted, firstly, a number of scientific doubts and, secondly, a
number of loopholes in the French regulations then in force.
160  The expert group's conclusions led the
authorities to draw up its first "asbestos plan" wh ich was presented in outline on 6 July 1995 to the
Council for the Prevention of Occupational Risks.161  The plan reflected the determination of the
French authorities to strengthen the existing preventa tive measures and to equip itself with the means
to obtain more detailed knowledge of the risks related to asbestos.
Third phase:  the asbestos plan of December 1995
258. The asbestos plan of December 1995 containe d immediate measures for the protection of
workers and the public, as well as initiating a joint independent scientific report on the effects onhealth of various varieties of asbestos.  This plan, whose measures are still in force today, is intended
to reinforce the protection of workers in the asbestos industry, and also, above all, to take into account
the risk inherent in asbestos in place for the public and workers in the repair and maintenance sectors.
The asbestos plan of December 1995 contains  the following provisions, in particular:
• The requirement for owners of buildings to identify flockings and laggings containing
asbestos before 31 December 1999, and to have the condition of the flockings and
lagging surveyed by a competent body in order to undertake the necessary works in
the event of deterioration
162;
• reduction of the occupational exposure limits in activities involving work in contact
with asbestos, to the lowest level technically possible, i.e. 0.1 fibre/cm3
(Decree 96-98 of 7 February 1996).163  The difference between the limit for "pure"
chrysotile (0.3 fibre/cm3  and amphiboles (0.1 fibre/cm3) which only concerned the
production sector, was abolished by Decr ee 96-1132 of 24 August 1996, with effect
from 24 December 1996;
                                                     
158 The EC point out that the Decree of 28 April 1988 prohibits the sale of crocidolite, subject to limited
exceptions, and certain products containing chrysotile, and makes it mandatory to label products containing
asbestos accordingly.  The Decree of 28 April 1988 was subsequently amended by Decrees No. 94-645 of26 July 1994, No. 98-668 of 26 July 1996 and No. 96-113 of 24 December 1996.   The Decree of 26 July 1994prohibits the use of all varieties of asbestos, except for chrysotile asbestos.  It also extends the list of productscontaining asbestos which are prohibited from sale.

• improved procedures for asbestos removal:  the power conferred on labour inspectors
to close sites where asbestos is being removed where the protective measures do not
seem to them to be adequate (amendment of Article L 231-12 of the Labour Code by
Law 92-1446 of 31 December 1992, Article 35 and Law 96-452 of 28 May 1996,
Article 39)164;  prohibition on the use of casual workers to carry out the work of
removing asbestos, introduction of a procedure of accreditation of firms
(Decree No. 96-98 of 7 February 1996);
• elaboration of specific rules for prevention suited to repair and maintenance
situations:  the need to enquire of the ow ner whether asbestos is present, mandatory
individual protection whenever the presence of asbestos is suspected (Decree 96-98
of 7 February 1996).
259. These provisions completed the general arrangements for information and training of workers
set out in the French Labour Code, by adapting them  to the risks related to the inhalation of asbestos
dust and the type and method of use of individual and collective means of protection.  The regulations
thus put in place satisfy the objective of reducing to the lowest level possible the risk presented by
asbestos in place.  In technical terms, they contain the tightest possible protection measures.
260. The introduction of French regulations on asbestos was accompanied by information
campaigns directed at trade federations and, more particularly, the construction sector.  All the French
regions and all those involved in the prevention of occupational risks prepared numerous
methodological guides, information leaflets, audiovisual programmes and training.  To increase
knowledge about the risks related to asbestos in the repair and maintenance sectors, the "EVALUTIL"database, which can evaluate asbestos exposure of users of asbestos-containing products, has been
made accessible via the Internet.  The Labour Inspectorate has been heavily involved and specially
trained in the context of the Ministry of Labour's priority actions.  Sites where asbestos is being
removed or sealed are strictly monitored:  all removal plans are studied, all sites where"friable"
asbestos and the vast majority of other asbestos removal sites are monitored by the LabourInspectorate.  For example, of 2,344 declared sites, 70 per cent were controlled in situ.   Apart from
their persuasive effect, the extent of which is difficult to measure, these inspections led to work being
stopped on 114 sites because the protection measures were judged by the Labour Inspectorate to be
inadequate, and have led to more than 3,000 notifications of failure to comply with French
regulations.
261. The labour inspectors observe, in regional reports of priority actions, that the regulations are
relatively well respected and that the asbestos risk is investigated and taken into account in major
works such as large-scale renovation, demolition and works carried by out large companies.  On the
other hand, in regional reports of priority actions, the labour inspectors also note, objective and
serious difficulties in enforcing the regulations in many small operations, particularly by private
individuals.  Indeed, the labour regulations are mandatory for employees and self-employed workers
but not for individual do-it-yourself enthusiasts.  In such situations, which by their nature areextremely diverse, little notice is taken of the need to investigate the presence of asbestos and take the
necessary protection measures.
The French decision to impose a ban
262. The INSERM report, which was submitted at the end of June 1996, to the Minister of Labour
and Social Affairs, showed the need to supplement the existing protection arrangements, as an
essential step to reduce the risk of asbestos in place to the lowest possible level, by a ban which would
                                                     
164 Idem., page 79.WT/DS135/R/Add.1
Page 77
stop the risk spreading.  The reasons for this are as follows:  (i) chrysotile is carcinogenic and it has
not been shown that there is a threshold below which it is harmless;  (ii) the vast majority of
mesotheliomas appear among "secondary users", particularly, in the construction sector, which means
a very large number of people exposed in a very wide variety of situations in which the so-called
"safe" use is inapplicable.  Protection measures in force prior to the decision to impose the ban, evenif technically the tightest possible, proved inadequate  to reduce the risks in all situations to the lowest
possible level.  That being the case, if the French authorities had not imposed a ban, they would have
knowingly allowed the volume of asbestos in place to  increase, thereby increasing the risk to workers'
health, particularly that of "secondary users" (worke rs in the repair and maintenance sector and do-it-
yourself enthusiasts).
2. Question by the Panel to Canada
Question 5:  With respect to Articles III:4  of GATT and 2.1 of the TBT Agreement, Canada
states that it is not invoking the argument of likeness of non-fibrous substitute products and
neither does it extend the argument of likeness to substitute fibres other than glass fibre,
cellulose fibre, PVA fibre and fibro-cement products containing such fibres (reply to
question 15 of the Panel).  Could Canada clarify if it considers that the Panel should limit its
findings and conclusions to the effect of the re gulations in relation to  these three substitute
fibres?
(i) Reply by Canada
263. Canada reiterates its reply to Question 15 of the Panel, as set out above in
paragraph 74 and 75.
264. In the case of Indonesia – Certain Measures Affecting the Automobile Industry, it was clearly
established that it was not necessary, for the purposes of Article III:2 of GATT, to determine whether
the Honda Civic was like the Indonesian Timor si nce the demonstration of the likeness between he
Toyota Corolla and the Timor was enough to establish the violation of Article III:2 of GATT.
165  We
note that the recent INSERM study on substitute fibres, Effects on Health of Fibres Replacing
Asbestos , dwells specifically on the fibres mentioned by Canada as being like in the meaning of
Article III:4 of GATT and 2.1 of the TBT Agreement, namely, glass fibres, cellulose fibre and
polyvinylalcohols (PVA).  INSERM states in its study:
"This study covered the main fibres used to replace as bestos:  artificial mineral fibres (glass, rock and
slag wool, continuous thread glass fibre, glass microfibres, refractory ceramic fibres), organic fibres
(para-aramid, cellulose).  The case of polyvinylalcoh ols (PVA) has not been considered because of the
dearth of scientific literature on them".166
265. For the purposes of Canada's argument under Article III:4 of GATT and 2.1 of the TBT
Agreement, Canada is of the opinion that the findings and conclusions of the Panel should consider
the effect of the regulations in relation to these three substitute fibres and fibro-cement products
incorporating them.
3. Questions by the Panel to the European Communities
Question 6:  Could you describe the type of meas ures applicable, in France, to substitute fibres,
in particular glass, cellulose, PVA, para-aramid and refractory ceramic fibres?

Page 78
(i) Reply by the European Communities
266. Substitute fibres are considered to be chemical substances.  As such, their manufacture, use
and sale are governed by a mass of complex European regulations which have been incorporated intoFrench domestic law.  In particular, both consumers and workers must be informed of the intrinsic
danger of such fibres by means of labelling and "risk warnings" based on the European classification
of their risk to human health.
167  This requirement to provide information also exists at international
level.  Discussions are currently taking place in an endeavour to harmonize classification systems at
international level.  At the moment, the European Union has a system of classification of chemicals
and chemical preparations which is applied uniformly throughout the member States, and
consequently in France too.  The preventative measures applicable to chemicals and chemicalpreparations vary according to the level of risk as determined by their classification.  The applicable
regulations depends on the level and type of hazard.  The following regulations, in rising level of risk
are applied cumulatively, depending upon the particular characteristics of the chemical or chemical
preparation:  (i) for chemical agents not classified as dangerous, reference must be made to the
traditional regulations on ventilation and air quality in the workplace
168;  (ii) for chemical agents
classified as dangerous the regulation on chemical risks has to be applied169;  (iii) for chemical agents
classified as proven human or animal carcinogens, the regulations on carcinogenic risks applies.170
Furthermore, breaches of these provisions, like all breaches of the provisions of the Labour Code andimplementing legislation are criminal offences pursuant to Article L. 263-2 which lays down financial
penalties (25 000FF per employee) and, in appropriate cases, a term of imprisonment.
267. Of the fibres mentioned in question 6, three fi bres are not classified as dangerous:  PVA,
para-aramid and cellulose.  Nonetheless, the general regulations on ventilation and air quality in the
workplace apply and mean that:  (i) systems for ventilation and dust capture at source must be
installed;  (ii) dust levels must be below the thresholds set out in the Labour Code.
268. Glass fibres are classified as irritant and carcinogenic "Group 3" (i.e. suspect in animals under
the IARC classification);  in this case the regulations on prevention of chemical risks apply, which
means that the employer must satisfy the following requirements:  (i) risk assessment (levels of
collective and individual exposure, methods envisaged to reduce them);  (ii) installation of collective
protective equipment;  (iii) supply and maintenance of individual protective gear;  (iv) training and
information for workers;  (v) signposting of premises where the substances are used;  (vi) an
explanatory notice on the risks and means of protection specific to each work place.  For this purpose
the employer has safety information sheets provided by the manufacturer, which give details of thecomposition of the product, the hazards and the prevention measures to be taken.
269. As ceramic fibres are classified carcinogenic "Group 2" (proven risk to animals under the
IARC classification), their use is subject to the regulations on prevention of carcinogenic risks, which
incidentally is more restrictive than that concerning chemical risks mentioned above, because in
addition it requires:  (i) substitution by a less dangerous product when that is technically possible;(ii) use of a closed system when that is practicable;  (iii) limitation of the quantities used and the
number of workers exposed;  (iv) reduction of exposure to the lowest level technically possible;
(v) special medical monitoring of workers.

270. Following the results of the collective INSERM report on asbestos substitute fibres, the
French authorities launched a plan of action on artificial mineral fibres (in particular glass wool and
ceramic fibres) which provides for:  (i) monitoring of the compliance of labelling of the various fibres,
in particular, glass wools;  (ii) monitoring of exposure levels;  (iii) improving knowledge in the area
of toxicology and epidemiology.
Question 7:  Canada claims that France should  have used two guiding principles to determine
which chrysotile asbestos products should be used:  (i)  risk assessment product by product and
use by use, and (ii) demonstration of the feasibility and effectiveness of "controlled use" for
each product.  Could the European Co mmunities comment on these arguments?
(i) Reply by the European Communities
271. Both Canada's arguments are incorrect for the following reasons.
272. First, neither GATT nor the TBT Agreement lay down any rule whatsoever on how to
perform a risk assessment.  Even the SPS Agreement, which is not applicable in this case and which
contains specific provisions on risk assessment, doe s not require the performance of a risk assessment
in the way suggested by Canada.171 
273. Secondly, there are in fact no internationally agreed and binding rules on how to conduct a
risk assessment for dangerous substances like asbestos.  In addition, neither national nor international
practice (e.g. by WHO, IARC, FAO/Codex Alimenta rius, etc.) support the views of Canada on the
two "guiding principles".  It is common practice to assess the risks posed by chemical substances or
other potentially dangerous products by evaluating in general the physico-chemical properties,toxicological and other relevant data on the pharmacologically active parent compound and its
metabolites, and the possible ecotoxicological effects where this is likely to be relevant to the
assessment of the risks posed by the substance in question.  When the risk assessment indicates that
an Acceptable Daily Intake (ADI) and a Maximum Residue Limit (MRL) can be set for the substance
or product in question, they can subsequently be used without further examination on a product byproduct and use by use basis, contrary to what is incorrectly suggested by Canada.
172  R i s k
assessment, however, is a very complex and interactive process and no one particular technique or
methodology is always appropriate for all cases.  Epidemiological data and occupational exposure
data may also be used to support toxicological data from in vitro or in vivo studies.
274. Thirdly, the WHO and IARC Reports that evaluated asbestos, including chrysotile asbestos,
do explain the methodology they used.173  A close look at them shows that, in fact, they evaluated the
risks posed by chrysotile asbestos to a very large extent in a way similar to the one suggested byCanada but have arrived at conclusions opposite to those of Canada.
                                                     
171 See, e.g., Article 5.1-5.2 SPS and the Appellate Body report in the Hormones  case, AB-1997-4,
paragraph 187.
172The European Communities note that a general overview of the principles applied by WHO and its
specialized agencies in the evaluation of food additives and contaminants in food may be gained by looking atthe WHO Environmental Health Criteria no. 70, Principles for the Safety Assessment of Food Additives and
Contaminants in Food,  Geneva, 1987.  A study by the US General Accounting Office on pesticides has also
demonstrated serious differences in the way a risk assess ment is carried out by several industrialised nations:
see US General Accounting Office, Pesticides – A Comparative Study of Industrialised Nations' Regulatory
Systems , Washington, 1993.
173 See WHO Environmental Health Criteria 203, Geneva, 1998, pp. 1-9, and IARC Monographs,
Supplement 7, Lyon, 1987, pp. 19-28 and 38-40.WT/DS135/R/Add.1
Page 80
275. Fourthly, the risk assessment carried out by WHO is  very similar, if not identical, to the one
performed by INSERM and confirms on all essential points the results of the INSERM Report.
276. Fifthly, as regards substances that have been classified as proven human carcinogens, such as
chrysotile asbestos, and for which there is no scientifically established threshold of exposure, the two
guiding principles suggested by Canada are in fact totally irrelevant, because any exposure tochrysotile or any kind of chrysotile-containing product may pose a risk to human health (because
there is no safe exposure threshold).  Therefore, the nature and number of the final products and their
use does not matter as such.  What is important is the fact that they contain the very carcinogenic
substance that has been evaluated, i.e. chrysotile asbestos.
277. Sixthly, it is not correct to suggest that France and the other competent international
organisations that have evaluated chrysotile asbestos failed to demonstrate the lack of feasibility and
effectiveness of the so-called "controlled use".  As the European Communities have explained indetail in their written and oral statements, cases of lung cancer and mesothelioma have been observed
or reported even in cases where strict measures have been taken to control exposure to asbestos.  It is
interesting to note that during the meeting of the Panel with the scientific experts on 17 January 2000,
none of the experts was aware of any specific case where the so-called "controlled use" advocated by
Canada was applied.  And even Canada, in the same meeting, failed to provide a specific example of acountry where such "controlled use" has ever been effectively applied.
278. To sum up, the existing rules permit France to apply its own, customary and normal rules on
risk assessment to asbestos.  This is what France did in this case.  The methodology applied by France
is similar, if not identical, to the one usually applied internationally and actually used by WHO and
the IARC in the case of asbestos.  It is up to Canada, not France, to perform the different, novel typeof risk assessment it now advocates in order to demonstrate the accuracy of its claims.  That Canada
has failed to do.
II. QUESTIONS TO THIRD PARTIES
C. 
FIRST SUBSTANTIVE MEETING - SESSION WITH THE THIRD PARTIES (2 JUNE 1999)
1. Questions from the Panel to Brazil
Question 1:  Could you please develop or expand upon the argument you make concerning
developing countries in paragraph 4.23 of your written submission, particularly in light of the
fact that this is not a point that has been raised by either party to the dispute?
279. In the Marrakech Declaration of 15 April 1994, adopted at the time of signature of the
Uruguay Round Final Act, Ministers welcomed the notably active role of developing countries in the
negotiations, declaring that "[t]his has marked a historic step towards a more balanced and integrated
global trade partnership."  (Paragraph 4.)  Ministers also recalled that the results of the negotiations
embodied provisions conferring differential and more favourable treatment for developing economies.
(Paragraph 5.)  These Ministerial statements reflect the achievement of the goal set out in Part I,
Section B, Paragraph (iv) of the 20 September 1986 Punta del Este Declaration launching theUruguay Round negotiations.  As set out in Brazil's third party submission,
174 this commitment to
special and differential treatment is embodied in Article 12 of the TBT Agreement.  The issue was not
raised by Canada because it is not a developing country.  It was not raised by the EC because, as
responding party, it has no interest in acknowledging its higher level of obligation to Brazil (and
Zimbabwe).  But, this does not detract from the EC' obligation to respect the special and differentialtreatment obligations established at Articles 12.2 and 12.3.  A Member's obligations do not depend on
                                                     
174See Section IV.A of this Report.WT/DS135/R/Add.1
Page 81
the procedural aspects of dispute settlement; rather, they are set out in the texts of the WTO
agreements, in this case the TBT Agreement, in particular.  In imposing the ban, France did not "take
into account the special development, financial and trade needs" of Brazil or Zimbabwe, as required
by Article 12.2.  Nor did France ensure that the ban "[did] not create unnecessary obstacles to
exports" of chrysotile from Brazil, as required by Article 12.3.  This is why Brazil has asked the Panelto scrutinize the ban closely, especially as it applies to the chrysotile exported by Brazil.  The ban's
unwarranted effects on Brazil and Zimbabwe provide a supplemental reason why the ban is
inconsistent with France's obligations under the TBT Agreement.
Question 2:  To what extent can modern contro lled use in both current and recent past practice
ensure adequate safety standards throughout th e life-cycle of products containing chrysotile
asbestos?
280. Current controlled-use policies are available to guarantee safety throughout the life-cycle of
chrysotile products.  First, as a preliminary matter, Brazil notes that the most current research
indicates that chrysotile alone does not present significant health risks.  (Please refer below to Brazil's
response to the EC Questions 22 and 23.)  Second, an examination of the life cycle of chrysotile
products indicates that procedures can be adopted to guarantee safe use of chrysotile.  The followingdiscussion breaks the life-cycle into three stages:  (i) manufacture; (ii) use and maintenance; and
(iii) disposal.  The product used as an example is chrysotile cement because it accounts for such a
large portion of the market.
(a) Manufacture
281. The safety of workers manufacturing chrysotile cement and chrysotile cement products can be
guaranteed through proper controls.  The following controls have been demonstrated to reduce
chrysotile concentrations to 0.1 f/ml:  (i) wet-process treatment (asbestos is mixed with water to make
a slurry from which fibres and dust cannot escape);  (ii) closed-process treatment (after workers load
airtight bags of asbestos into machines, the process is air-tight through the point where the finalproduct (in which the fibres are encapsulated) is produced);  (iii) filtered ventilation systems (to
remove from the air those few fibres that escape the wet, enclosed process);  (iv) special treatment of
workers' clothing (because those few fibres that do remain often cling to clothing, Brazilian cement
plants provide special work clothes and launder them appropriately on-site); and (v) personal hygiene
measures (supply shower facilities and double dressing rooms for workers to further address fibre
deposition).
(b) Use and Maintenance
282. By "use and maintenance," Brazil refers to the installation and maintenance of chrysotile
cement products.  The  "waste" from use is disc ussed below under the heading "Disposal/Recycling."
For chrysotile cement products, the procedures set out in ISO-7337 guarantee a high level of safety in
installation and use.  ISO-7337 establishes guidelines for breaking/cutting/drilling cement products so
that they can be installed with minimal release of fibres.  In general, ISO-7337 requires breaking orcutting with special saws, using wet process and/ or vacuum dust extractors.  Brazil also would
recommend proper training.  Perhaps licensing is appropriate for certain procedures (e.g., removing
flocking).  At all other points during use, the fibres are encapsulated.  However, in certain climates,
regular inspection (e.g., every 5 years) of exposed products (roofing tiles, in particular) may be
appropriate.  Any exposure from degradation of the product can be halted by using the spray sealantcurrently recommended for application to flocking.WT/DS135/R/Add.1
Page 82
(c) Disposal/Recycling
283. Disposal/recycling of asbestos cement product s and "waste" should be handled with measures
similar to their manufacture end-use - proper wet controls and cutting or breaking methods.  Please
recall that the EC focus on remediation of flocking is not at issue.  Rather, the issue here is the
disposal/recycling of encapsulated used chrysotile cement products and waste.  In cement products,the chrysotile remains encapsulated.  Indeed, when buried, for example, in a landfill, the fibres are as
inert (or more inert) as they are in naturally appearing ores containing asbestos.
(d) Personal Protection Equipment
284. At each stage, proper controls reduce exposure and health risks to de minimis  levels.  With the
use of personal protection equipment (PPE), exposure can be reduced to zero.  PPE absolutely
guarantees no exposure and thus no risk to health.  PPE could constitute "deep sea diver suits."
However, for any modern application involving chry sotile products, a simple air filter, coupled with
proper working procedures, will eliminate exposure.  In addition, Brazil refers the Panel to Brazil's
answers to EC Questions 10 (flaws of the linear risk model), 16 (safety of modern uses) and 22 and 23
(chrysotile that is not mixed with or accompan ied by any amount, even a trace amount, of amphibole
or substitute fibres presents no risk; modern uses of chrysotile present no risk).
2. Questions from Canada to Brazil
Question 1:  What is Brazil's position on the re lative health effects of chrysotile, amphiboles and
man-made fibres?
285. In considering the question of relative health effects, one must keep in mind four basic truths.
First, as accepted and employed by the EC in its rulemaking (see Brazil's response to EC Question 7),
the toxicity of fibres is defined primarily by reference to the size, shape and durability and duration in
the lung of the fibre in question.  Thus, experts posit that any fibre with characteristics similar to
chrysotile (due to its having been engineered to substitute for chrysotile) must be a suspected
carcinogen.
175  Chrysotile has been proven safer than amphibole asbestos.  As INSERM concedes and
the studies cited by Brazil in response to EC Question 5 establish, this fact is not subject to question.Equally incontrovertible is the proposition that some man-made fibres have been proven more
dangerous than chrysotile or even amphibole.  See the discussion and the studies cited at Brazil's
response to EC Question 7.  Recent research demonstrates that chrysotile presents no health risk.
Please refer to the discussion and studies presented at Brazil's responses to EC Questions 22 and 23.
Scientists now suspect as a result of recent studies that health effects once associated with chrysotile
are due to the fact that the past studies examined subjects exposed to chrysotile and amphibole and
that the amphibole was responsible for the health effects.

Page 83
Question 2:  What is Brazil's position as to whether and how chrysotile use can be controlled to
guarantee safety?
286. For years, Brazil has controlled the mining, production and use of chrysotile and chrysotile
products to guarantee safety.  As explained by Brazil in response to Panel Question 2, controls existfor every part of the life cycle, from the time chrysotile is mined until chrysotile cement products are
disposed of.  Even as the EC presents the grossly exaggerated picture of workers equipped as
"veritable deep sea divers," the EC provides the seed of an admission which, germinated,
compromises its position.  The EC concedes that use can be safe and, in doing so, admits that a ban is
not the least trade restrictive remedy required to achieve its desired level of protection.  But, in any
case, the EC's picture is quite distorted.  For a country that chooses to disturb flocked asbestos,
guaranteeing worker safety by equipping workers as veritable deep sea divers may be rational;however, for modern controlled uses of chrysotile, the only relevant personal protective equipment
(PPE) is a simple air filter, which reduces already safe exposure levels to zero.
Question 3:  How does Brazil interpret the expression "current controlled use"?
287. The expression "current controlled use" is the key to this proceeding.  Brazil is not defending
past uses, e.g., flocking, the use of amphibole, or the use of naturally exposed asbestos in solution as a
white-wash for buildings.  Brazil is defending against France's ban a limited range of beneficial, safe
uses:  the use of chrysotile in asbestos cement products and friction products.  Brazil has demonstrated
that these uses, which compose the majority of the market, are safe.  Exposure can be controlled so
that PPE is not needed to guarantee worker safety.  In these limited applications, safety is guaranteedby controls, but PPE can be used to reduce exposure to zero.
3. Questions from the European Communities to Brazil
Question 1:  Brazil alleges  in a number of instances (e.g. in paragraph 4.28 of its written
submission) that in the past France imported and used mainly amphibole asbestos.  On what
factual and/or statistical data are these allegations based?  Could Brazil provide them to thePanel?
288. Brazil's understanding that France once imported much larger amounts of amphibole than it
now does is based on the history of world use of asbestos, not on French import statistics.  For some
time, countries did not distinguish between imports of chrysotile and the far more dangerous
amphibole asbestos.  During this period, the two types were used virtually interchangeably and
countries, even Brazil, imported substantial amounts of  amphibole.  As the EC likely is aware, French
import statistics do not distinguish chrysotile and amphibole.
Question 2:  Could Brazil define what it means by "uncontaminated" chrysotile?
289. By "uncontaminated", Brazil means chrysotile that is not mixed with or accompanied by any
amount, even a trace amount, of dangerous amphibole or substitute fibres.  An attached scientificassay demonstrates that the chrysotile that Brazil mines and exports is uncontaminated.
177  Moreover,
as discussed in detail in the answer to EC Question 5, INSERM also recognizes that chrysotile is less
hazardous than amphibole.  Nonetheless, INSERM did not address the health effects of exposure to
chrysotile alone.  The distinction is quite important.  As McDonald (1998) concludes " … it now
seems fairly widely accepted that the carcinogenicity of the amphiboles, crocidolite in particular, is
                                                     
177 Miriam Cruxên Barros de Oliveira et al. , Technical Report Nr. 36 889, Instituto de Pesquisas
Tecnológicas, São Paulo (Brazil), 1998.WT/DS135/R/Add.1
Page 84
appreciably greater than of chrysotile …"178.   Thus, amphibole is viewed widely as the source of
toxicity that at one time in the past was associated with the use of chrysotile.
Question 3:  Could Brazil provide concrete written evidence supporting its allegation
(e.g. paragraphs 4.3 and 4.9 of its written submission) that the French Decree at issue aims to
deal exclusively with a public outcry, public pressure and to appease domestic sentiment and isnot based on any scientific evidence, given th e volume of internationally available scientific
evidence documenting the risks of asbestos to human health?
290. Obviously, the French Government did not accompany the Decree with an official statement
admitting the Decree was passed to appease the French public.  No government would do such a
thing.  However, the facts preceding and surrounding the Decree and the INSERM Report, as well as
the timing of the decisions taken, demonstrate that the Decree was not aimed primarily at protectingpublic health (for if it was, why are substitutes that are Class II carcinogens not banned?), but was
designed to quiet a disturbed populace.  In this regard, Brazil refers to Canada's arguments (contained
in Section III.B.3 of this Report) which set out a chronology showing how a series of unfortunate
decisions, coupled with the public's strong response, led the French Government to ban chrysotile,
without scientific basis.  The text of the INSERM Report also supports this conclusion.  At page 140,INSERM notes that exposure to flocked asbestos in buildings is the "core of the current concerns,"
and emphasizes that the subject is "extremely controversial."  INSERM states that French courts had
wrestled with the issue and ignored science in tying sickness to indoor exposure.  Id. at pages 141-2.
Ironically, INSERM concludes that the data "do not confirm" that maintenance and service personnel
in "asbestos-sprayed buildings" (flocked buildings ) experienced an increased risk of respiratory
abnormalities.  Id. at pages 143-4.
Question 4:  Could Brazil provide concrete evidence supporting the allegation (paragraph 4.3 of
its written submission) that the INSERM report was merely a scientific "cover" for a previously
taken political decision?
291. Brazil refers to the answer to EC Question 3. In  addition, Brazil notes that the fact that the
INSERM Report was merely scientific cover for the political decision is confirmed not merely by
reference to the events of the time, but also by a review of the Report itself.  Even a cursory review
shows that INSERM ignored evidence that did not conform to the opinion it apparently was instructed
to reach.
Question 5:  Could Brazil provide written evidence supporting the allegation (paragraph 4.3 of
its written submission) that "especially the spraying of brittle amphibole" caused the asbestos-related health problems in France?
292. Flocked asbestos led to the health problems that most concerned the French officials
contemplating a ban.  That is incontrovertible as a review of the INSERM Report and the answer to
EC Question 3, above, demonstrates.  Likewise incontrovertible is the fact that flocking occurredduring the time prior to any ban on amphibole asbestos.  Indeed, INSERM states (page 18) that
chrysotile fibres commonly were mixed "with up to 40 per cent amphibole fibers," due to the different
properties of the two types of fibres.  The Report prepared by INSERM at the request and under the
direction of the French Government recognizes that chrysotile is much safer than amphibole and thus
that amphibole is of primary concern for negative health effects.  INSERM concedes this pointthroughout the Report. For example, at page 102, INSERM states, "subjects exposed mainly to
chrysotile have a lower risk of mesothelioma than subjects exposed to amphiboles or a mix of fibers.
"  Later, discussing Hughes et al.  (1987) and Weill et al.  (1977), INSERM reports that the "prevalence
                                                     
178 McDonald, J.M., Unfinished Business:  The Asbestos Textiles Mystery  (invited editorial), Ann.
Occup.  Hyg., Vol. 42, No. 1 at 3 (1998).WT/DS135/R/Add.1
Page 85
of radiographic asbestosis was found to be higher in the plant that handles more amphibole asbestos.
"  Id. at page 323.  INSERM further concedes that "crocidolite has a greater fibrogenic effect than
chrysotile."  Id. at page 326.  INSERM concludes that the studies demonstrate that the dose-effect
relationship is much stronger with amphibole fibres than with chrysotile, as regards both asbestosis
and the other pathogenic effects of asbestos.  Id. at page 327.  Anecdotal evidence supports the
conclusion. INSERM explains the higher inciden ce of sickness in Australia and New Zealand by
reference to the "widespread use of the crocidolite these two countries produce."  Id. at page 158;
[sic] see also id. at page 171 (concluding that, in Australia, "the incidence of mesothelioma is
particularly high due to widespread crocidolite use").  This view is widely shared.  In 1996, Health
and Safety Executive of Great Britain concluded that:
"[v]ery few cases of mesothelioma can be reliably a ttributed to chrysotile despite the many thousands
of workers who have had massive and prolonged exposures … In contrast, mesotheliomas have beenobserved among some workers who experienced only brief exposures to amphiboles."
179
293. A U.S. Government official has expressed a similar view.  According to Malcolm Ross,
mineralogist for the U.S. Geological Survey, scientific studies show chrysotile is not as great a health
risk as amphibole:  "[t]here's no non-occupational risk  with chrysotile. … In the workplace, chrysotile
should not show any noticeable increase of disease if it is controlled."180   These studies and
conclusions demonstrate that the primary concern regarding risk to human health is exposure to
amphibole, most of which occurred during past uses.
Question 6:  Could Brazil provide a copy of th e full American Society of Mechanical Engineers
(ASME) study it has cited (paragraph 4.5 of its written submission), as well as a reference to
where it has been published?
294. Brazil does not cite the ASME study anywhere in its submission.  Rather, Brazil cites the
Fifth Circuit's recounting and analysis of the testimony during the court proceeding of one of the
study's authors.
Question 7:  In paragraph 4.6 of its written su bmission, Brazil claims that "available scientific
data" would show that, compared to chrysotile, man-made fibers produced in France present
greater risks when use is not controlled?  Could Brazil provide copies of the relevant scientific
articles and/or other data?
295. The available scientific literature demonstrates that chrysotile is safer than many if not all
substitutes.  Indeed, recent research suggests that chrysotile poses no health risk.  In this respect,
Brazil attached the following papers and studies:  (i) Cossette (1998), concluding that iron ductile and
PVC pipe present health risks far greater than that presented by chrysotile cement pipe;
(ii) Hesterberg (1992), reporting that 35 per cent of hamsters treated with a variety of ceramic fibresdeveloped mesotheliomas;  and (iii) Peraud et al.  (1994), concluding that, as compared to all types of
asbestos, the man-made mineral fibres silicon carbide, JM 104/475,  B1M , and B3K, have a
"moderately higher toxic effect" (pages  570-2).  In addition, the scientists and doctors attending The
Proceedings of the Workshop on Health Risks Associated with Chrysotile Asbestos  (1994) concluded
that:
"With the exception of the textile industry, the slopes of the exposure response curves for lung cancer
in the various chrysotile industry sectors were shallow, with no detectable risk of an extremely low
level of risk of lung cancer associated with exposure to chrysotile asbestos at and below lifetime

cumulative exposures of 30 fibres/ml-years.  No chrysotile related increased risk was detected at
considerably higher exposures in the mining sector."181
296. Moreover, in his report to the EC (EC document number ECB/TM/15(97)), Dr. Bernstein
analysed statistically all available biopersistence studies, chronic intraperitoneal [injection] studies
(IP) and chronic inhalation studies on fibres.  This and subsequent research demonstrates thatchrysotile is safer than refractory ceramic fibres (RCF), glass fibres, p-aramid fibres and cellulose
fibres.  Dr. Bernstein's analyses for the EC were reviewed and accepted by the Ad-Hoc Group of
Experts commissioned by the EC and consisting of scientific experts from EC member states and
industries.  The results of the analysis clearly showed that one can use inhalation biopersistence
clearance half-times to predict IP tumour results, the number of long fibres remaining at 24 months inthe Chronic Inhalation Studies and a score of pulmonary fibrosis in the Chronic Inhalation Studies
(tumours were not used as an endpoint as only a single fibre type (RCF) was tumorigenic in these
studies).  Based upon this scientific analysis, the EC Fiber Directive included in Note Q the provision
that:
"The classification as a carcinogen need not apply if it can be shown that the substance fulfils one of
the following conditions:  (i) a short-term biopersistence test by inhalation has shown that the fibreslonger than 20 µm have a weighted half-life less than 10 days; or (ii) a short-term biopersistence test byintratracheal instillation has shown that the fibres longer than 20 µm have a weighted half life less than40 days, or (iii) an appropriate intra-peritoneal te st has shown no evidence of excess carcinogenicity; or
(iv) an absence of relevant pathogenicity or neoplastic changes in a suitable long term inhalation test."
297. The results from Dr. Bernstein's chrysotile biopersistence study show that chrysotile fibres are
rapidly removed from the lung.  Fibres longer than  20 µm are cleared with a half-time of 1.3 days,
most likely by unravelling into shorter fibrils.  This is consistent with the known chemistry of
chrysotile.  Shorter fibres also are cleared rapidly from the lung, with fibres 5-20 µm clearing even
faster (T ½ = 2.4 days) than those < 5 µm in length.  These short fibres were never found clumped
together but appeared as separate, fine fibrils, occasionally unwound at one end.  Short free fibresappeared in the corners of alveolar septa, and fibres or their fragments were found within alveolar
macrophages.  The same was true of fibres in lymphatics, as they appeared free or within phagocytic
lymphocytes.  These results support the evidence presented by McDonald and McDonald that the
carcinogenicity of chrysotile largely depends on whether it is mixed with amphibole.
182  T h u s ,
chrysotile clears faster than most current glass fibres for which in the EC system, the clearance half-time of long fibres must be less than 10 days in order to be exonerated.  In addition, chrysotile clears
substantially faster (T
½ = 1.3 days) than long p-aramid fibres which following a 90-day inhalation
exposure cleared with a half-time of 95 days.183   Finally, chrysotile clears considerably faster than
cellulose fibres for which the clearance half-time of WHO fibres was between 1046 days and
infinity.184  One should note that the INSERM Report ignores the above analysis by Dr. Bernstein, as
well as other studies comparing chrysotile to p-aramid and cellulose, even though they pre-date the
INSERM Report.

Question 8:  In footnote 11 of paragraph 4.10 of its written submission, Brazil states that
"because only the INSERM report preceded the Ban, the Ban must be supported by the report
alone."  Could Brazil explain why the INSERM report alone should support the ban given the
volume of internationally available scientific evidence clearly documenting the risks of asbestos
to human health?  What provisions of the GATT 94 and/or the TBT Agreement (assuming thisis applicable) support this proposition?
298. First, the Government of France ordered the INSERM Report precisely for the purpose of
conducting a risk assessment and supporting the ban.  In promulgating the ban, it relied on the
INSERM Report as the risk assessment. For the ban to be legitimate, it must be supported by the risk
assessment upon which it is based.  That is a matter of logic, not of WTO rules.  More importantly,
however, INSERM and the French Government failed to conduct an unbiased risk assessment. TheEC now appears before this Panel, suggesting that  the actual risk assessment was not published, but
occurred behind closed doors in a process in which French Government officials reviewed the
INSERM Report and all of the relevant studies the EC concedes with this question that INSERM
ignored.  Then, and only then, suggests the EC, did the French Government issue its decision to ban
chrysotile.  There is no evidence that any such complex, thorough process occurred in the 24 hours
between delivery of the INSERM Report and the issuance of the ban.  Moreover, to countenance the
EC's attempt to insulate the French risk assessment from examination would be to make a mockery of
the TBT Agreement.  It would allow any Member to conduct a secret analysis and issue its foregone
conclusion that a ban was necessary, without any oversight or discipline, whatsoever.
Question 9:  In paragraph 4.11 of its writte n submission, Brazil states:  "Finally, INSERM
concedes that, although the health data it ap plied to chrysotile is from past, massive and
prolonged exposure to amphibole (…)".  Could Br azil provide the exact location (page number)
where INSERM has stated this?
299. Throughout the Report INSERM relies on data from human exposure and animal exposure
(mostly rats and hamsters).  All of the studies of human exposure focus on exposure that occurred 20,
30, 40, 50 and 60 or more (for the earliest studies) years ago.  See, e.g.,  INSERM Report at Tables 1
and 2 to Chapter 13, pages 321 through 323; Table 2 to Chapter 8, page 164; and Table 4 to
Chapter 8, page 166, summarizing data on past exposure of workers in various asbestos product plants
and other occupations, and comparing the incidence of disease in men and women.  This point is not
subject to debate.  The primary fact differentiating current exposure from these older periods of
exposure is that, during the older periods of exposure, amphibole was commonly used, and had not
yet been banned.  See Brazil's answer to EC Qu estion 5; INSERM Report at  page 18.  Nowhere does
the INSERM Report distinguish between exposure to chrysotile only and to chrysotile mixed with
carcinogenic amphibole.  Another difference is that, in contrast to current practices, the work
processes were not controlled and workers had little personal protective gear, much less safety
accommodations such as showers and special clothing.  A review of the dates of the studiessummarized in the tables referred to above, and of the ages of the subjects and the length of exposure
indicates that many of the exposures studied were quite dated.  See also the discussion of latency
periods and disease onset at pages 156-59 of the INSERM Report.
300. Moreover, even in plants using "chrysotile," studies suggest that a significant amount of the
asbestos used was amphibole.  For example, INSERM reports that the asbestos used in theCasale Monferrato plant was "chrysotile, but approximately 10 per cent of the total amount of
asbestos was crocidolite."  INSERM Report at page 137.  Further to the point, INSERM concludes
regarding exposure from industrial sources, that "in all positive studies reported, when asbestos fibre
type was specified, the fibres involved were from the amphibole group, or fibres containing some
amphiboles (amosite, tremolite or crocidolite)."  Id. at 140.  This applies even to the animal studies
INSERM relied on.  According to INSERM:WT/DS135/R/Add.1
Page 88
"Animal experiments also make it possible to evaluate the dose-effect relationship.  Most of the studies
have used massive quantities of fibers at concentrations far higher than seen clinically in humans.Recent work by Quinlan et al (1994) analysed the effects of lower concentrations, ranging from 0.1 to
10 mg of crocidolite per cubic meter of air."
185
Question 10:  In paragraph 4.12 of its written subm ission, Brazil criticises the use of the "linear
risk model" used by France.  Could Brazil provide scientific evidence explaining why this
model, which is a very widely used one, is unfounded or inappropriate?
301. Brazil already has introduced scientific evidence regarding the limitations of the linear risk
model as applied to chrysotile.  Brazil assumes that a statement by INSERM would qualify, at least
for France and the EC as "scientific."  As INSERM itself conceded, but apparently the EC wishes to
ignore, the linear risk model cannot produce "scientifically certain knowledge" (INSERM Report
at 239).  Moreover, much of the research upon which INSERM relies for other propositionsdemonstrates that a safe threshold exists.  For example:  (i) at Table 2 to Chapter 6, page 88, INSERM
reports that Wistar rats exposed to chrysotile in the amount of 6 fibres mg/m
3 developed no lung
tumours, in contrast to rats exposed to higher amounts or to other fibres;  (ii) at pages 88-89, INSERM
recounts that hamsters exposed to various amounts of chrysotile in three separate studies (Lee et al.
(1981), Smith et al.  (1987) and Hesterberg et al.  (1991)) did not develop lung tumours; and at
page 104, INSERM recounts a study of intermittent exposure at high concentrations and continuous
exposure at lower concentrations (Davis et al.  (1980)), and concludes that "the authors found no
significant effect on the tumour rate in the different treatment groups."  In spite of these and other
studies, INSERM supported the linear risk model.  But when it came time to state why, INSERM
(page 408), equivocated:
"No argument based on the analysis of existing epidemiological data, direct or indirect, supports the
belief that no-threshold linear extrapolation based on data corresponding to higher levels of asbestosexposure (adopted in this report to quantify the risks associated with low-level exposure) is not the
most plausible uncertain model."
302. The conclusion, confused as it is, is utterly implausible  given the evidence cited above from
the Report itself, much less that discussed below.  Moreover, earlier in the report, INSERM concedes
that, even if one adopts a linear risk model, a safe threshold nonetheless exists.  According to
INSERM (page 104), if a:
" … straight-line relationship is maintained for smaller doses, it means there is no minimum below
which all risk disappears.  However, the tumour latency period increases in animals as the dose falls.This means that a threshold value should exist in practice, corresponding to a dose for which the
latency period is greater than the "natural" life expectancy of the animal in question."
303. Thus, INSERM concedes that, even assuming that all exposure is dangerous, at some lower
exposure level, the latency period would be so long that no tumour would occur before death from
natural causes.  The most recent literature on the subject rejects outright the linear risk model.  For
example, Mossman and Churg now conclude that "asbestosis does not appear until a thresholdexposure level has been reached …" and "[e]pidemiological studies indicate  very clearly that the
development of asbestosis requires heavy exposure to asbestos and provide strong evidence that there
                                                     
185 INSERM Report at page 275;  see also id. at pages 86-7;  id. at page 155 (asbestos-related disease is
linked to "massive use").  The effect of massive doses is well documented in the scientific literature on "lungoverload"  Thus, one might question how the dose-effect relationship can be defined by studying the effects of"massive quantities of fibers at concentrations far higher than those seen clinically in humans."  At the least, one
would not expect such data to define the safe threshold.  The existence of a safe threshold for chrysotile is
discussed at length in Brazil's response to EC Question 10.WT/DS135/R/Add.1
Page 89
is a threshold fibre dose below which asbestosis is not seen …".186   In 1994, Churg et al.  concluded
that:
"Our results show clearly that, despite known historic exposure to amosite and chrysotile, amosite is by
far the predominant residual fiber, and there are correlations between amosite measures and disease.
Chrysotile was present inconsistently and in relatively small amounts, and no correlations were found
between chrysotile measures and disease."187  
304. According to Professor Patrick Brochard of the Pellegrin Hospital in Bordeaux, France,
"chrysotile is carcinogenic, but not below a certain dosage level, unlike amphiboles".188  Health and
Safety Executive concludes in the Review of Fibre Toxicology that, for chrysotile, "the balance of
toxicological evidence does not support the non-threshold model for asbestos-induced lung cancer.  A
practical threshold  is likely".189   Even the WHO suggests that a threshold exists for chrysotile.  In
discussing the incidence of mesothelioma in wo rkers exposed to chrysotile, the WHO concluded
in 1998 that "[n]one occurred in workers exposed for less than two years."190   And this statement was
in regard to workers in the mining and millin g sectors, likely handling chrysotile and amphibole
fibres.
Question 11:191  Has the article of Brazil's Law No. 9055, cited in paragraph 4.17 of its written
submission, according to which miners and wholesalers are prohibited from supplying
chrysotile or substitute fibers to any company that does not comply with any provision of thelaw, already been put in practice?  Could Brazil provide written evidence thereof, including
copies of all relevant court or administrative decisions, statistics on the number of cases in
which the article has been applied, etc.?
305. There has been no occasion to enforce this or any other article.  As demonstrated in a
document provided by Brazil to the Panel,
192 supplies are immediately withdrawn as soon as non-
compliance is discovered.  The supply resumes only after compliance measures demanded by ABRAhave been implemented.  More importantly, the question is irrelevant to this proceeding. Brazil
describes its own practice merely to show the Panel that exposure can be controlled.  France's
obligation is to adopt the least restrictive means of  achieving its own level of safety.  That might
require controls or restrictions in addition to those imposed by Brazil.
Question 12:  Has the article of Brazil's Law No. 9055, cited in paragraph 4.17 of its written
submission, according to which there should be  prompt Department of Justice enforcement
against infractions of that law, already been put in practice?  Could Brazil please provide
written evidence thereof, including copies of a ll relevant court or administrative decisions,
statistics on the number of cases in wh ich the article has been applied, etc.?
306. See Brazil's response to EC Question 11.

Question 13:  Could Brazil please provide al l available information on the results of its
"research into and confirmation of the health ef fects of chrysotile and its substitutes" foreseen
in its Law No. 2350 (paragraph 4.18 of its written submission)?  Please provide copies also of
those results.
307. Two types of research are under way:  epidemiological research and research on bio-
persistence. The epidemiological research is far fr om completion, but tracks the health of thousands of
asbestos workers in Brazil.  Results or a summary thereof will be provided as soon as they are
available.  The preliminary findings on bio-persistence are presented in Dr. Bernstein's study,193
provided by Brazil to the Panel.  Moreover, as discussed in response to EC Question 7, researchperformed in the EC and elsewhere demonstrates that substitute fibres present significant health risks.
Question 14:  The so-called Tripartite Agreements (paragraph 4.19 of its written submission),
"make ABRA", the Brazilian Asbestos Association "responsible for providing the companies
with technical assistance regarding controls and preventive measures." Has ABRA ever
provided such assistance to French client companie s of Brazilian chrysotile producers?  If so,
please provide evidence thereof.
308. Yes, ABRA provides assistance to those companies that join as members and request
assistance.  As the French Government well knows, among ABRA's members is Brasilit S/A, a
French company that is one of the largest cement fibre producers in Brazil.  (Other ABRA members
are German and United States companies.)  Moreover, ABRA is available to assist any French or EC
company needing assistance after the ban is lifted.
Question 15:  Brazil's written submission does not clearly explain what the Brazilian legal
requirements and practices are regarding the waste generated by end-users of products
containing asbestos, for instance when parts of asbestos-containing-products have to be cut off
to fit certain uses or when buildings, installation s, and other structures containing asbestos are
demolished?  Could Brazil please provide detailed information, including references tolegislation, on this question?
309. Brazilian environmental legislation addresses "residues," including chrysotile residues.  The
Tripartite Agreements require zero residue or complete recycling of residues in the industrial
processes for producing chrysotile cement products.  Also, imports of amphibole were banned years
ago and the asbestos Brazil produces is chrysotile. Because Brazilian asbestos use is limited to
chrysotile and chrysotile products, no health effects have been associated with disposal of cut-offpieces of asbestos cement pipe or roofing.  However, cement companies have adopted procedures
where they accept and recycle "waste."  End users are directed to return the waste to the point of
purchase, which then returns it to the producer.  The producer recycles the waste in its industrial
process.  Certainly, France has the ability to regulate chrysotile "waste," just as it regulates wastes
from many other production processes.
Question 16:  In paragraph 4.33 of its written submission, Brazil claims that what it calls
"modern-day" products containing chrysotile do not contain loose, friable chrysotile fibres.
Could Brazil provide the data it possesses on ex posure levels occurring when these products are
actually used in practice (for in stance when cutting or sawing th ese products in workplaces or
homes, or when demolishing the buildings and other structures in which they are present)?
310. The Brazilian Government has not conduct ed or sponsored any studies on workplace
exposure levels.  However, as the EC well knows, many studies document that exposure levels

Page 91
depend upon the controls used.  Brazil directs the EC to the INSERM Report at page 70.  There,
INSERM sets out exposure levels for uncontrolled activities.  The levels range from 10 f/ml for a
person silly enough to change a friction element on a machine for making corrugated fibreboard and
then clean it with a blow gun, to 0.15 f/ml for a person removing a false ceiling.  Do-it-yourself
activities such as cutting an asbestos seal, and drilling holes in sprayed asbestos fall in between theselevels and for the most part are under 1 f/ml.  But these value are for uncontrolled use.  Controlled use
would yield much lower exposure rates.  Moreover, controlled use, plus, as INSERM terms it
"protection measures"  would yield no or de minimis  exposure. Indeed, at page 70, INSERM refers
briefly to a study (CORN) in which the concentrati ons of fibres for "work in buildings" ("dismantling
false ceilings, cable passageways, electrical work and encapsulation"), ranged "between 0 and
0.228 f/ml."  On the related topic of the safety of controlled use, INSERM makes several interesting
points.  These data are relevant, INSERM states at page 71, because:
"In the area of para-occupational exposure, related in particular to do-it-yourself activities, there are no
data in the literature allowing documentation of the subject.  In each basic operation - welding, cutting
asbestos board, cutting or drilling asbestos cement and so on - it seems justifiable to consider the
emission peaks to be identical to those found during industrial operations of the same type.  Thepossible differences in exposure levels, in terms of inhaled doses, are eventually to be found inexposure times, as the do-it-yourselfer does not perform such operations as often as occupationalworkers."
311. Thus, experience with occupational exposure to asbestos is applicable to do-it-yourselfers,
provided one recalls that exposure times are far less for do-it-yourselfers than for asbestos workers.
The following discussion recounts INSERM's conclusion regarding occupational exposure.  First,INSERM notes that mesothelioma stems from pa st occupational exposure. According to INSERM
(page 182), "stringent worker protection measures" can eradicate mesothelioma:  "[b]ecause of the
occupational source of asbestos exposure, mesothelioma incidence is not rising in a few countries that
implemented stringent worker protection measures at an early date."  Regarding asbestosis, INSERM
(page 327) notes that "[t]he current levels of exposure in industries that use asbestos directly shouldlead to an end of confirmed cases of asbestosis (Doll et al. , 1985)."  INSERM (page 327) also cites
the Peto study, which the EC heavily relied on, for the proposition that "[e]xposure prevention
measures have removed this disease [asbestosis] from the list of the causes of death at a British
Textiles firm."  Thus, contrary to the conclusion reached by the French Government and the position
adopted by the EC in this proceeding, chrysotile can be safely used, and even INSERM concedes this
fact.
Question 17:  In footnote 42 of paragraph 4.27 of its written submission, Brazil seems to imply
that the TBT Agreement would require a "rat ional link" between the measure and the risk
assessment, in apparently the same sense as the case law cited therein from the SPS Agreement
requires.  Could Brazil identify the provision of the TBT-Agreement that justifies thisallegation?
312. A rational link requirement is implicit in the text of the TBT Agreement.  Article 2.2 states
that a technical regulation "shall not be more trade restrictive than necessary to fulfil a legitimate
objective."  The risk assessment is the basis of the level of safety chosen, which, in turn, is the basis of
the measure taken.  Absent any rational link between the measure taken and the risk assessment, this
chain breaks.  Thus, there must be a rational link to ensure that the measure taken is not more traderestrictive than necessary to fulfil the legitimate objective, the general statement of the level of safety,
which is based on the risk assessment.  Moreover, the very nature of the WTO agreements suggests
that a rational link is necessary.  One does not find in international agreements a "rationality clause."
Rather, the parties to the agreement understand that the provisions are to be interpreted rationally.
Does the EC here suggest that a measure with no rational link to a risk assessment should be foundWTO consistent?  Brazil notes that it presented the panel reports addressing the SPS Agreement toWT/DS135/R/Add.1
Page 92
ensure that the Panel was informed that a similar issue already had been addressed and resolved under
the SPS Agreement.
Question 18:  Has the study by Dr. David M. Bernstein, cited by Brazil, been published in a
peer-reviewed journal?
313. The study by Dr. D. Bernstein was planned in two phases.  The first phase (now complete)
involved the evaluation of the biopersistence and morphological disposition of chrysotile fibres
following inhalation exposure.  Dr. Bernstein presented portions of the first phase 10 November 1998
at the Giornata Scientifica sulle Fibre di Vitro in Rome.  The second phase is currently under way and
involves a similar study of biopersistence and morphological disposition of both short and long
tremolite fibres following inhalation exposure.  Dr. Bernstein has confirmed that these studies will be
published in a peer-reviewed scientific journal when the results from Phase Two are available.  In theinterim, Dr. Bernstein has published or presented the following reports:  (i) a publication providing
the scientific basis leading the European Communities to incorporate fibre biopersistence as a key
parameter in assessing fibre toxicity
194;  a presentation of the chrysotile biopersistence and
morphological disposition results at a scientific colloquium presented at the Universidade Federal de
São Paulo (Brazil) 19 March 1999;  and an abstract by Dr. Bernstein entitled The Inhalation
Biopersistence and Morphologic Lung Disposition of Pure Chrysotile Asbestos in Rats  has been
accepted for presentation at the "7th International Symposium on Particle Toxicology" which will be
held in Maastricht 12-15 October 1999.
314. More fundamentally, however, Brazil disputes the relevance of the EC' question.  What
matters is the soundness and relevance of the research, not whether it has been published yet.  Thesefacts INSERM concedes at page 135 of its Report.  There, INSERM discusses a study by
Camus et al. , describing it as "an as yet unpublished study whose preliminary results have been
communicated to us."  INSERM not es that, although unpublished, the study is particularly valuable
because it was prepared, in part, by "particularly competent experts."  Id. Dr. David M. Bernstein is a
particularly competent expert.  As the EC well knows, the EC has hired him (as has the Governmentof Germany) to study and develop recommendations c oncerning the proper control of fibres.  Indeed,
he is still in the employ of the EC.
Question 19:  In paragraph 4.28 of its written submission, Brazil refers to the "modern-day
internationally recognised cont rolled-use level of 1f/ml," based on a reference to a 1991
document.  Is Brazil aware that in 1998 the WHO concluded that no threshold has been
identified below which asbestos, including chrysoti le, can be considered to be safe (see Annex II-
1 of first written EC submission)?
315. Yes.  Many different organizations have reached different conclusions about safe exposure
levels.  The United States and Canada, for example, have adopted exposure levels that are
significantly higher than those of Brazil.  A careful review of the WHO study indicates that the WHO
conclusion was based on concern regarding chrysotile mixed with amphibole:
"The more rapid removal of chrysotile fibres from the human lung is further supported by findings
from animal studies showing that chrysotile is more rapidly cleared from the lung than are amphiboles
including crocidolite and amosite."195

316. These conclusions led the WHO to recommend research on the effects of exposure limited to
chrysotile without any exposure to amphibole.196  This is precisely the type of research
Dr. David M. Bernstein is conducting.
Question 20:  Could Brazil elaborate on the rela tionship and possible limits of Article 12, in
particular 12.3, of the TBT Agreement with the right of Members to take measures to protecthuman health in their territory?
317. No relationship exists, but this is not an issue in the present case.  Brazil totally agrees that
protecting public health is a legitimate objective.  However, here France has taken a measure that is
more trade restrictive than necessary to fulfil the purported objective of protecting public health.
Moreover, France did not even consider the fact that Brazil mines and exports only chrysotile, not
amphibole or a chrysotile/amphibole mixture.  This is inconsistent with the TBT Agreement.  (Pleaserefer also Brazil's response to Panel Question 1.)
Question 21:  Could Brazil please provide data, including scientific evidence, of the number of
cases of mesothelioma observed and their evolution during the last 20-30 years in its territory?
318. No case of lung cancer or mesothelioma from exposure only to chrysotile has been reported
(this currently is being confirmed in the epidemiological study).  Only three cases total of
mesothelioma have been reported in Brazil.  All of these were in individuals with substantial exposure
to amphibole.
Question 22:  In paragraph 4.14 of its written submission, Brazil states that "Recent research
focusing on uncontaminated chrysotile demonstrates why it presents no health riskwhatsoever".  Could Brazil provide copy of this scientific evidence?
Question 23:  In its oral presentation, Brazil  stated that INSERM has not taken account of
studies which show that there is no risk associat ed with what it calls "m odern" use of chrysotile.
Could Brazil provide copies of the studies concerned, including references to the relevantparagraphs?
319. Brazil has addressed these questions with one answer because they raise similar issues.
320. Brazil has provided a copy of Dr. Bernstein's study.
197  Please also refer to three other studies
presented by Brazil,198 which, in sum, " … support the hypothesis that adverse effects are associated
rather with the fibres retained (amphiboles), than  with the ones being cleared (largely chrysotile)."199
These studies show that, and explain why, modern uses of chrysotile alone present no health risk.  In
addition, please recall that in 25 years of operation, the Capivari Chrysotile Cement Plant in Brazil
has not experienced one case of mesothelioma (please refer to Brazil's presentation in Section IV of
this Report).  This health history is similar to th at at other work sites using chrysotile (and even some
in which chrysotile was predominant in a mix of chrysotile and amphibole).  In the Executive
Summary of The Workshop on Health Risks Associated with Chrysotile Asbestos,

Dr. Graham W. Gibbs emphasized the importance of the "absence of lung cancer and mesothelioma
risks in workers exposed to reportedly high concentrations of chrysotile in a UK asbestos cement
plant in which silica was not used, as well as two similar plants in Zimbabwe …".200  A clean bill of
health also has been assigned to chrysotile as used  by shipyard workers and insulators in the Pacific
Northwest of the United States.  According to Churg and Vedal (1994):
"Our results show clearly that, despite known historic exposure to amosite and chrysotile, amosite is by
far the predominant residual fiber, and there are correlations between amosite measures and disease.Chrysotile was present inconstantly and in relatively small amounts, and no correlations were found
between chrysotile measures and disease."
201  
4. Questions from the European Communities to the United States
Question 1:  In paragraph 4.47 of its submission, th e US states that chrysotile asbestos is no less
toxic than other forms of asbestos. Could the US please develop this statement further,
including, if possible, references to and/or copies of the scientific grounds on which it is based?
321. The United States refers the Panel to its third party presentation in this case (see Section IV of
this Report).  In addition, the United States points out that a review of lung burden studies in human
subjects and mechanistic studies does not provide convincing evidence for the "amphibole
hypothesis" that chrysotile may be less potent than amphiboles in the induction of mesothelioma.202
Animal studies support the conclusion that all types of asbestos should be considered equally potent
with respect to the production of either lung cancer or mesothelioma.203  For instance, in an inhalation
study in which groups of rats were exposed to the five UICC asbestos fibre types204, amosite,
anthophyllite, crocidolite, Canadian chrysotile, and Rhodesian chrysotile, comparable incidences of
lung tumours and mesotheliomas were induced by all types of asbestos fibres.205  While
epidemiological studies clearly demonstrate a link between asbestos exposure and increased risk of
lung cancer and mesothelioma, most of the studies involve workers that were exposed to mixed fibretypes.  Nevertheless, there are a number of epidemiological studies of workers that were exposed
predominantly to chrysotile and one study in which the exposure was solely to amosite.
206  There is no
statistically significant difference in the risk of lung cancer seen in the group of workers exposed only
to amosite compared to those exposed predominantly to chrysotile in textile production or to mixed
fibres in manufacturing.207  In addition to evidence showing the causal relationship of exposure to
chrysotile asbestos and cancer, ample evidence shows that exposure to chrysotile asbestos poses a
significant risk of non-malignant respiratory disease.208  One study, which reported mortality and

208 In the mid-1980s, OSHA performed a quantitative risk assessment to justify amendments to its
standards.  This risk assessment was published in 1986 as "Occupational Exposure to Asbestos, Tremolite,WT/DS135/R/Add.1

assessed dose-response relationship for asbestosis in a cohort of asbestos textile workers exposed only
to chrysotile, found that 17 (5.5 per cent) of 308 deaths were due to asbestosis or pulmonary fibrosis.
A second study reported data showing a linear relationship between cumulative fibre dose and
morbidity.  A third study reported a linear dose-response relationship between asbestosis and levels of
asbestos dust. These data also support the hypothesis of no threshold, or low threshold for asbestos,since there is increased risk at cumulative exposures as low as 37 fiber-years/cc.
209
322. Because of the carcinogenicity and asbestosis-producing effects of all asbestos types, the U.S.
Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration
(OSHA) of the U.S. Department of Labor do not distinguish among asbestos fibre types in their
regulations.210  In testimony in 1990, Richard Lemen, Assistant Director of the U.S. National Institute
for Occupational Safety and Health, summed up the case against distinguishing among asbestos fibre
types in public policy.  We quote from his testimony:
"Recent reports have appeared in the scientific literatu re to suggest that different forms of asbestos are
not equally pathogenic.  …  However, there is a great deal of uncertainty associated with these findings
and equally important contradictory evidence.  Re sults from research involving animal bioassays
present a strong case that there is no safe form of asbestos.  …  Not only has chrysotile been found tobe as potent as crocidolite and other amphiboles in inducing mesotheliomas when injectedintrapleurally.  … it has been found equally potent in inducing pulmonary neoplasms throughinhalation exposures (Wagner et al. , 1974).  Chrysotile also appears to be more potently fibrogenic and
carcinogenic than amphiboles, in relation to the quantity of dust deposited and retained in the lungs of
rats (Wagner et al, 1974).
…  In fact chrysotile fibers are much more chemica lly and biologically reactive than amphibole fibers.
…  These fibers are less readily detected in the tissue after the damage is done.  …
At this time, there is no compelling evidence to justify different public health policy for different
asbestos fiber types…".
323. Lemen also notes that the Royal Commission study submitted by Canada to the Panel
recommended that textile manufacturing using chrysotile be banned, and concluded that "all fibre
types can cause all asbestos-related diseases."211
Question 2:  In paragraph 4.47 of its submission  the United States writes:  "[s]pecification of
work practices and other controls does not avoid all the risks associated with a hazardous
materials such as chrysotile asbestos." Could the US please expand on this statement, and if
possible provide (references to) the facts and data that support this viewpoint?

210 At the Panel’s meeting with third parties, Brazil alleged that worker exposure standards of the U.S.
Department of Health and Human Services differ for chrysotile and other asbestos.  EPA and OSHA are not
aware of any such standards.  A 1996 HHS Public Health Service report referred to an exposure standard of the
American Conference of Governmental Industrial Hygienis ts (ACGIH), but it should be clear that the ACGIH is
not  a U.S. government agency and its threshold values are not regulatory standards.

324. In response to the statements throughout the Canadian submission that "controlled use" will
bring the risk associated with chrysotile asbestos to "undetectable" levels, in its third party's
submission to the Panel the United States has discussed the fact that "controlled use" will not
completely eliminate the risk caused by asbestos.  In 1994 OSHA reduced its permissible exposure
limit for occupational exposure to asbestos to 0.1 fibres per cubic centimeter (f/cc) as a time-weightedaverage measured over 8 hours.  Based on its risk assessment OSHA found that the excess cancer risk
at that level would be a lifetime cancer risk of 3.4 cases per 1,000 workers and a 20 year exposure
cancer risk would be 2.3 per 1000 workers.  OSHA foun d that this risk is still significant and the
United States Court of Appeals for the D.C. Circuit affirmed this finding.  OSHA set this limit
because it believed that it was the lowest exposure level using feasible engineering and work practice
controls.  It is not a risk-free limit.  In other words, there is a still significant health risk at or below
OSHA’s permissible limit.  For this reason, and because some employers do not adequatelyimplement the work practices, many asbestos workers rely on respirators (masks).  Asbestos removal
work often is done by poorly paid and poorly trained workers.  OSHA has found that respirator
effectiveness depends on how well the masks fit, how often they are replaced, cleaned and repaired,
and how well employees are trained.  In spite of rules requiring good respirator practices, studies
show that many employers do not comply and that respirator-wearing employees still get highexposures.  OSHA recently calculated, based on studies of respirator effectiveness, that up to 40 per
cent of employees who wear respirators get essentially no protection when their employers do not
adequately fit, clean and replace the respirators they wear.
212  Also, where employees are protected
solely by masks, the uncontrolled asbestos dust released during their work is airborne and
contaminates the work-site.  A major work practice in  asbestos handling is wetting the tool used to cut
or disturb the asbestos material or wetting the ma terial itself.  When the material dries, the dust
becomes airborne.
325. Most asbestos-containing products are inst alled, disturbed or removed on construction
work-sites.  Construction jobs typically invo lve transient employees who may work for many
different employers; short term work; and lack of training opportunities compared with factory
employment.  These factors make enforcing work practices and good respirator practices difficult.
Another problem is that renovation work occurs in  buildings that may or may not contain asbestos.
This uncertainty leads to under-protecting the workers.  Also, construction worksites have many
immediate safety hazards.  Employers and employ ees may concentrate on avoiding these immediate
hazards and pay less attention to the risks of chronic hazards caused by asbestos.  The difference
between exposure levels when employers use available controls and when they do not is striking.
During OSHA’s rulemaking, the U.S. Argonne National Laboratory (ANL) reported to OSHA
concentrations during cutting operations of asbestos-cement sheet that ranged from 8 to 14 f/cc
without local exhaust as compared to 0.04 to 0.15 f/cc when local exhaust was used.  Similarly,
sampling data collected by the U.S. National Institute of Occupational Safety and Health (NIOSH)
during the installation of asbestos-cement sheet ranged up to 0.32 f/cc when local exhaust ventilation
was not being used.  Similarly, when cutting asbestos-cement pipe with an abrasive disc saw andcutting and machining pipe without a shrouded tool or without using wet methods, exposures
exceeded OSHA’s exposure limit of 0.1 f/cc.  Many asbestos product manufacturing and installation
jobs expose workers to over the OSHA permissible exposure limit of 0.1 f/cc when dry operations
take place.  For example, OSHA determined in 1986 that "it is generally not feasible for the dry
operations of carding and spinning (in textile operations) to comply with" the then permissible limit of0.2 f/cc.  OSHA also found that in the asbestos reinforced plastic manufacturing process, the "problem
exposure areas" appear to be in dry finishing operations.  These operations are similar to dry
mechanical operations in other asbestos products manufacturing industries and include grinding and
sanding, which OSHA has determined may not be feasible to achieve exposure levels below 0.2 f/cc

without the use of respirators.213  Based on OSHA ’s risk assessments, lifetime cancer risks at these
levels are 6.7 per 1000 exposed workers.
326. Moreover, as discussed in both the U.S. and EC submissions to the Panel, the steady
enlargement of the stock of asbestos and asbestos-containing materials in society, which results from
failure to ban further use of asbestos, may engender substantial risks where demolition or maintenancetakes place and the composition of materials is not obvious.  As indicated in the U.S. third party's
submission, EPA has asbestos regulations in place which govern work practices and other controls to
be used during the demolition of buildings
214, and maintenance activities in schools.215  T h e s e
regulations require those engaging in such activities to identify asbestos-containing materials, or to
assume that certain materials are asbestos-containing, prior to commencement of the work.  If the
composition of the material is unknown, in the absence of such regulatory requirements concerning
work practices and controls, workers could be unprotected.  The United States believes thatunprotected workers who undertake building demolition or maintenance activities involving
asbestos-containing materials would be subject to the exposure levels set forth by OSHA in Table 6 of
the preamble to its final rule governing occupational exposure to asbestos.
216  Table 6, entitled
"Estimated Occupational Exposure to Asbestos and Reduction in Cancer Risk in General Industry and
Shipyards as a Result of the Final Revision to the Standard",217 presents average baseline exposure
levels in the absence of respiratory protection and other primary controls and work practices.218  These
figures are given in the third column of the table, entitled  "Potential mean fiber exposure with
minimal controls (f/cc)".219  Such exposure levels would be expected to occur for unprotected
workers.  Based on this table, the exposure level fo r an unprotected worker involved in a demolition
project would be 9.9 f/cc, or almost one hundred times the permissible exposure limit of 0.1 f/ccestablished by OSHA.
220  The 1991 Health Effects Institute-Asbestos Research report estimates that
the lifetime risk to workers historically exposed to levels of that magnitude is approximately
200,000 per million, or 1 in 5.221
327. EPA has issued public guidance concerning asbestos-containing products and their
management.222  In addition, EPA has issued lists of suspect asbestos-containing materials.223  But it
cannot be assumed that many "Sunday carpenters" know about such guidance, especially since they
may not even be aware that they are working with asbestos-containing materials.  The data in Table 6

of the preamble to the OSHA rule224 could be used to estimate exposures to these unprotected persons
as they periodically engage in repair activities such as those involving ceiling tiles, plumbing, roofing,
and drywall, based on such factors as the frequency and length of these intermittent exposures.
Question 3:  In paragraph 4.51 of its submissi on the US states: "The use of a linear model is
appropriate for a quantitative estimation of the risks associated with low levels of exposure to
asbestos ….".  Could the US further elaborate on this statement, explaining why it considers the
use of a linear model – which implies that there is no threshold below which there is no
carcinogenic risk – appropriate?
328. As indicated in the U.S. third party's submission (footnote 4, paragraph 8, and Exhibit 15),
studies of workers exposed to asbestos in the workplace (occupational exposures) link such exposures
to high incidences of lung cancer and mesothelioma.  However, since workplace exposures toasbestos are higher than general environmental exposures, these occupational exposures lead to an
incidence of disease that is considerably higher than for the general population.  The International
Agency for Research on Cancer (IARC) and th e World Health Organization’s International
Programme on Chemical Safety (IPCS) recognize that there is no conclusive evidence to demonstrate
that there is an exposure level for asbestos below which there is no risk, i.e., there is no "threshold"for asbestos.  Even the Report of the Royal Commission on Matters of Health and Safety Arising from
the Use of Asbestos in Ontario stated: "Most epidemiological studies of asbestos workers that have
demonstrated an excess lung cancer risk associated with the inhalation of asbestos have produced
results consistent not only with a linear relationship between cumulative dose and mortality, but also
consistent with the absence of a threshold."
225  EPA uses a linear model to estimate the risks
associated with low levels of exposure to asbestos because of the observed linearity of the response in
occupational studies and because of the incomplete understanding of how asbestos causes diseases in
humans.  In order to estimate and project excess risks at the low level of exposures to which the
general public is subject for asbestos, EPA utilizes a mathematical model that shows excess risks as
simply proportionate to exposures at low levels (low-dose linearity).  This procedure uses a curve todescribe the excess incidence of disease observed at higher exposures (in the occupational setting) and
takes a straight line to project from this excess to the lower-exposure environment of the general
public.  EPA believes that this approach is a reasonably protective way to address the issue of effects
associated with low levels of exposure to asbestos.
329. Furthermore, as the United States points out in its submission, the limited data that exist for
low levels of exposure to asbestos relating to the incidence of mesothelioma also indicate a linear
relationship.  In addition, the following should be noted, as indicated in the U.S. submission.Canada’s statement that "no epidemiological study to date has detected a higher health risk [than the
linear model] resulting from low levels of exposure"
226 does not take into account that, by their very
nature, epidemiological studies are capable of detecting only relatively large incidences of cancer.
Null results from epidemiological studies conducted at low exposure levels do not prove the absence
of carcinogenic effects at such levels because su ch results can arise from such factors as inadequate
study design or small population size.  In 1986, OS HA also published a quantitative risk assessment
of asbestos, as a basis for amendments made in 1986 and 1994 to the OSHA asbestos standards. The
risk assessment made the following key findings concerning the dose-response relationship in the case
of asbestos.  With regard to lung cancer, the data from several well-conducted epidemiologic studies
show that a linear model best describes the dose-response relationship.  With regard to mesothelioma,

a linear model is reasonable, fits the data well, and is the best estimator of risk.227  As noted in the
U.S. submission, IPCS found a linear dose-response relationship for mesothelioma in its 1998 risk
assessment on chrysotile.
330. OSHA conducted a public hearing in 1984 with participation by major scientists and
researchers in the field, including Dr. Kenny Crump, who testified that the linear model "has beenwidely used … for asbestos and lung cancer."  Dr. William Nicholson and Dr. Hans Weill also
supported the use of the linear model to predict lung cancer risk.  Dr. Weill testified: " … as far as the
shape of the curve for the important malignant consequences of asbestos exposure, I think we are all
in agreement. . . that the evidence does not permit us, nor does concern for public health or prudence
permit use . . .  (of) risk analysis on any basis other than linearity of exposure and response and in a no
threshold model."
Question 4:  Does the US consider that any of  the currently used substitutes in the US for
chrysotile asbestos are as dangerous or more dangerous than chrysotile?
331. The big picture of asbestos is that asbestos-exposed workers are right now being diagnosed
with disabling asbestosis and mesothelioma that has clearly been caused by asbestos exposure.
Asbestos-exposed workers are also being diagnosed with lung cancer.  Because lung cancer is alsocaused by exposure to other toxic agents, it is sometimes difficult to prove that it was the asbestos
exposure that caused the lung cancer in these individuals.  However, looking at the epidemiological
studies of workers, there is no doubt that the asbestos exposure causes lung cancer, and that the
workers' exposure either caused the lung cancer or  played a large part in causing lung cancer (as
discussed above, no significant difference exists between the toxicity of chrysotile asbestos and otherasbestos).  The question above asks whether there is an equivalent or stronger causal relationship to
human disease or death in the case of substitute fibres or products containing them.
332. To begin with, as stated in the U.S. submission, in some instances asbestos use in a product
(e.g. an asbestos-lined hot pad) is not essential, and the "substitute" consists of simply subtracting
asbestos from the product, or using other materials such as iron or ceramic for the same purpose(e.g. an iron or ceramic trivet) or otherwise reformulating the product so that neither asbestos nor
substitute fibres are used.  In this case the health effects of substitutes are nil or trivial.  As indicated
in the U.S. submission, there is no evidence that any of the currently used substitutes in the U.S. for
chrysotile are as dangerous or more dangerous than chrysotile. The only fibre that has been shown to
be more hazardous than chrysotile is another naturally occurring fibre, erionite.
228  However, erionite
is not currently used in commerce.  Based on the current understanding of how fibres can cause
adverse health effects, available data indicate that the differences in physical structure and propertiesbetween substitute man-made mineral fibres (MMMFs) and chrysotile, such as the larger diameter of
MMMFs and the fact that they break transversely rather than longitudinally to shorter fibres, may
render some MMMF substitutes less dangerous than chrysotile.   No MMMF has the same magnitude
of carcinogenic potential as asbestos.  A man-made mineral fibre, refractory ceramic fibre, has been
shown to have considerable potency in some laboratory animal studies, but the legacy of suffering anddeath found with asbestos has not occurred.  The high cost of refractory ceramic fibres has limited
their use to high-temperature industrial operations. As a general matter, exposures to fibreglass have
been lower than asbestos fibres.  This may be due to the inherent property of fibrous glass to have
fewer airborne fibres of a size that is deposited in the lungs.

5. Questions from the European Communities to Zimbabwe
Question 1:  In its oral statement, Zimbabwe ap pears to argue that the so-called controlled use,
including all the protective measures relating the reto, is capable of "minimizing" risk to human
health.  Could Zimbabwe expand on what it means by "minimize", i.e. which level of risk – and
thus chrysotile-caused diseases – would still remain and how much of that risk would beacceptable to Zimbabwe?
333. Zimbabwe first of all wishes to state that, being a natural product, chrysotile asbestos is
present, for example, in the air we breathe and that some exposure is thus inevitable.  There is
therefore no question of eliminating exposure altogether.  This said, Zimbabwe recalls that
the 1998 Task Group has clearly stated that the risks to humans are conditional on exposure. The goal
for responsible governments must therefore be to reduce exposure.  It is the contention of Zimbabwethat as a result of the application of risk control measures the risk of exposure to asbestos dust can be
minimized - so much so that the use of chrysotile asbestos can be considered safe.  There is therefore
no justification for a complete ban on the use of chrysotile asbestos.  Zimbabwe submits that this
conclusion is valid for both "primary" and "secondary" users of chrysotile asbestos.  Regarding the
former, Zimbabwe notes that the 1998 Task Group has confirmed that:
"Data from industries where control technologies have been applied have demonstrated the feasibility
of controlling exposure to levels generally below 0.5 fibres/ml.  Personal protective equipment can
further reduce individual exposure where engineering controls and work practices prove insufficient."
334. In Zimbabwe the fibre levels at workplaces where chrysotile asbestos is mined, milled or
processed are indeed below 0.5 fibres/ml/eight-hour period.  The aim is to bring those levels down
even further to 0.3 fibres/ml.  It is thus entirely possible for a developed country like France to
achieve its target level of 0.1 fibres/ml.  As concerns "secondary" users of chrysotile asbestos,Zimbabwe recalls that it has stated in paragraph 4.82 of its written submission that the:
"Combined use of high-density products made from asbestos-cement, which inherently are low-risk
products, coupled with adequate risk control measures minimize the risk of exposure to asbestos dust".
335. Zimbabwe thus believes that the combined  use of inherently safe products and adequate risk
control measures would enable France to achieve the maximum exposure level it deems acceptable.Zimbabwe finds itself in agreement on this point with Canada and the supporting evidence adduced
by it.229
Question 2:  In paragraph 4.98 of its written submission Zimbabwe suggests putting "asbestos
warning messages" next to buildings.  Can Zimbabwe explain why there would still be a need
for this type of warning if, as it alleges, co ntrolled use results in encapsulating indefinitely
chrysotile in cement?
336. Zimbabwe wishes to remind the EC that the relevant part of paragraph 4.98 of Zimbabwe's
written submission states as follows:
"While Zimbabwe recognizes that it may not be readily apparent to an inexperienced person whether or
not he/she is handling a product containing asbestos fibres, it is by no means justification for instituting
a far-reaching ban on products which might contain asbestos fibres.  […] Where the materials havealready been installed or incorporated, say, in a building, Zimbabwe does not see why there could not

d'hygième et de contrôle des fibres minérales, Pa ris, 1993, referred to by Canada (see Section III.B.7).WT/DS135/R/Add.1
Page 101
be, for instance, an asbestos warning message next to the evacuation instructions on a notice board of
that building."
337. Zimbabwe has also stated in paragraph 4.81 of its written submission that:
"… products made from asbestos-cement are products of high density and thus chrysotile asbestos
fibres are firmly blended into the final product [footnote omitted].  This reduces to a minimum thelikelihood of fibres being released into the air an d thereby posing a health hazard to human beings."
338. Contrary to what the EC tries to suggest, th ere is no contradiction between the two above-
mentioned statements made by Zimbabwe in its written submission.  The EC has contended that no
measure was available to France other than a complete ban of chrysotile asbestos and of products
containing chrysotile asbestos, if France were to achieve its public health objective.  The EC relies,
inter alia , on the argument that it may not be readily apparent to an inexperienced person whether
he/she is handling or dealing with a product cont aining asbestos fibres.  In its submission, Zimbabwe
addressed this argument put forward by the EC a nd Zimbabwe pointed out to the Panel that France
could have very easily required asbestos warning messages to be posted in buildings, for example, so
as to alert "secondary users" of the presence in buildings of chrysotile asbestos, if and where
appropriate.  The EC' argument does therefore not provide a justification for a ban on chrysotile
asbestos.  It is true, as the EC rightly points out, that asbestos warnings in buildings are in principleunnecessary in view of the fact that chrysotile as bestos fibres today are encapsulated permanently in
cement products.  The EC nevertheless asserts  that there could still be a risk of exposure to asbestos
dust whenever the cement-products are installed, maintained or repaired.  Zimbabwe has not contested
this.  Zimbabwe has, however, pointed out that ther e is a range of measures which would be available
to France to effectively control such risks of exposure.  All of these measures stop short of imposing
outright bans.  Thus, Zimbabwe's submissions are by no means internally inconsistent.
Question 3:  Could Zimbabwe explain whether training courses and the certification referred to
in paragraph 4.98 of its written submission are the only elements of the so-called "controlled
use" which can minimize risk, or does the postul ated "controlled use" require also other types
of measures?
339. In a sweeping and grossly exaggerated statement the EC has claimed that "Once on the
market, there is no further reasonable means of controlling the use of asbestos and, in particular,
controlling commonplace operations (cutting, sawing, …) that many persons may have to carry
out".230  Zimbabwe refutes this argument in its third party submission and cites specific and less
trade-restrictive measures which could have been used by the French Government.  Even assuming
arguendo  that the EC' concern about control were justified with regard to do-it-yourself users of
asbestos-containing products, Zimbabwe has submitted that, if indeed the French Government was soconcerned about those users of asbestos-containing products, it could have easily banned the sale of
such products in all do-it-yourself outlets.  As an additional measure, the French Government could
also have restricted the handling of asbestos-made products to certified experts, thus eliminating
exposure of inexperienced private users to asbestos.  Through certification the Government could
ensure that training meets certain minimum standa rds and thus enables the individuals concerned to
engage in safe work practices.
340. Zimbabwe also addressed the question of how the French Government could have sufficiently
protected occupational  "secondary users" of chrysotile asbestos other than through an outright ban on
asbestos.  As explained in Zimbabwe third party' s submission, the French Government "could have,
for example, required certification, which would only be bestowed upon an individual once he/shehad successfully followed information and training courses on the use and handling of asbestos-
                                                     
230 See arguments of the EC in Section III.C.1.(c) (ii).WT/DS135/R/Add.1
Page 102
containing products.  The French Government could also have laid down the precise work practices
and technical appliances that must be used in all contacts with asbestos-containing products.  To
ensure compliance, the regulations could authorize the imposition of heavy fines or a custodial
sentence in the event of a wilful disregard of the government's regulations.  Needless to say, it is also
open to a Member to run information campaigns.  Thus, it emerges clearly from this statement thatcertification, which would be conditional upon completion of, inter alia , training courses, is not the
only element of "controlled use".  In any event, th is statement must be read together with the
paragraphs where Zimbabwe has set out the types of measures that together make up "controlled use".
It might be added here that in Zimbabwe's view, periodical medical surveillance of workers can and
should be an integral part of "controlled use", notably in the case of "primary" and occupational
"secondary" users of chrysotile asbestos.
Question 4:  Could Zimbabwe comment on  the findings of the study by Cullen et al. , Chrysotile
Asbestos and Health in Zimbabwe, 1991 Am. J. Int. Med. 19, 171-182, which establishes a net
excess of mesothelioma cases of workers in mines and mills of chrysotile in Zimbabwe?
341. Zimbabwe disputes the assertion by the EC that the study by Cullen et al.  establishes a net
excess of mesothelioma cases of workers in chrysotile mines and mills in Zimbabwe. At page 178 ofthe study referred to it is stated that "[m]ajor x-ray abnormalities were rare in the population, with
only four having evidence of TB and three having nodules or masses that potentially represented
cancer."  This could hardly amount to conclusive evidence in support of the assertion by the EC.  In
fact, pleural disease was also surprisingly uncommon in the population which was examined.
Eighty-five of the subjects had parenchynal changes of whom 65 were in grade 0/1.  The fact that thestudy in question does show a relationship between parenchynal change and cumulative doses merely
confirms the need for risk control measures.  In no way does it establish a case for a complete ban on
the use of chrysotile asbestos.  It is worth noting here that there is another study by Cullen et al.
entitled Chrysotile Asbestos and Health in Zimbabwe - Analysis of Miners and Millers Compensated
for Asbestos-Related Disease Since 1980  (1991 Am. J. Int. Med. 19, 161 – 169). This study was not,
however, specifically on workers of chrysotile mines and mills in Zimbabwe.  This was a case study
on cases certified as having pneumoconiosis by the Pneumoconiosis Board in Zimbabwe.
342. The fact that this study showed cases of asbestos-related disease does not mean that the origin
of those cases can be traced back to chrysotile mines and mills in Zimbabwe.  The two cases referred
to in the study (numbers 19 and 20), where the histological examination confirmed mesothelioma,
were cases of individuals who had also worked in South African crocidolite asbestos mines.  They
were thus not exposed exclusively to chrysotile asbestos dust.  Another case referred to in the study(number 12) had also worked in a crocidolite mine in South Africa for five years.  This finding is
confirmed by the records of the National Cancer Registry, which have been carefully maintained since
1940 in Bulawayo.  The records show no more than 15 cases of mesothelioma.  In a detailed study
undertaken by Dr. Baloyi et al.  of those 15 cases, 14 were found to involve individuals who have had
mixed exposures, i.e. exposure to both crocidolite and chrysotile asbestos dust.  In the remaining case,no exposures could be established.  It is very important to note in this connection that in any event all
the findings referred to were the result of past exposures.  The control measures which have been put
in place at the chrysotile mines, mills and manufacturing units in Zimbabwe since then mean that
comparable exposure levels will never occur again.WT/DS135/R/Add.1

6. Questions from Brazil to the European Communities
Question 1:  In regard to the INSERM Report:  (a) does it contain any original research
(research performed by INSERM during the time the report was prepared)?  (b) does it review
any study regarding current controlled uses (post 1990 uses of chrysotile products)?  (c) does it
purport to review all available scientific studies?   (d) does it review the then current research
performed on the subject by and for the EC, in particular, that regarding bio-persistence and its
relationship to disease?  (e) if the answer to any of these questions is "no", the report cannot
support the ban, can it?
343. The INSERM Report bases its conclusions on the analysis of 1200 international scientific
studies, and reviews the status of international scientific knowledge concerning asbestos-related risks
at the time of its adoption.  It should be pointed out that all the studies on so-called controlled use andon bio-persistence available in 1996 were examined and taken into account in the INSERM Report.
The French ban is thus fully justified scientifically.  In addition, we do not understand Brazil's
reasoning, which amounts to saying that one negative reply, for example to the question in
subparagraph (a), would deprive the French Decree of a scientific basis in the light of the large
volume of scientific data from the international sources existing on the subject.
Question 2:  Why has France not banned all Class I carcinogens?
344. Brazil appears to be referring to an obligation of consistency which does not exist either in the
GATT 1994 or in the TBT Agreement.  It should be noted that, to our knowledge, no country has
imposed a general ban on all Class I products (proven human carcinogens), but several have alreadybanned asbestos.  There is no international text imposing a general ban on all Class I products.  France
imposed a general prohibition on asbestos as a result of a risk assessment.  Risk assessment must be
specific to each product, and the ensuing national risk management decisions are different according
to each product concerned.  Of the Class I carcinogens, none has been used in such a widespread way,
in products, spreading the carcinogenic risk when they are used, and sold to the general public.  Mostof these products are subject to very strict marketing restrictions and are usually used in an isolated
environment as synthesis intermediates.  Thus, they are no longer present in the finished products and
hence do not spread the carcinogenic risk when the end-product is used.  Besides, none of these
products has caused as many deaths or occupational illnesses.
Question 3:  How will the ban protect handymen from existing asbestos?
345. The French measure by prohibiting the use of any type of asbestos, including chrysotile
asbestos, provides effective protection by stopping future human exposure to risk from this substance.
The fact that quantities of asbestos, because of past use, remain and thus may continue to provide a
source of risk, does not diminish at all the right of France to take the measure in question to stop
further exposure to the risk from new applications .  The implicit logic in Brazil's question is that
because of possible risks from existing asbestos France should continue adding further risks.  Thistype of reasoning the EC contests.  In any case, France has taken indeed very serious and strict
measures to protect handymen from existing asbest os.  They have been communicated to the Panel
231.
Question 4:  Does not France regulate the use of  pesticides through use restrictions, labelling
and disposal requirements and the like?  Are not many of these pesticides extremely toxic?  If
these types of dangerous products can be regulated to control risk and avoid improper use anddisposal during the entire product life cycle, how can France maintain that chrysotile in
contrast cannot be regulated?
                                                     
231 Affections professionnelles consécutives à l'inhalation de poussières d'amiante, Tableau n° 30
(document submitted by the EC to the Panel).WT/DS135/R/Add.1
Page 104
346. The rationale of regulating the use of pesticides is completely different from that of the ban
on the use of asbestos.  Use of pesticides is allowed, after proper evaluation, in order to protect
human, animal or plant life or health from pests, diseases, illnesses, etc.  So although toxic, they serve
a specific purpose and their use is authorized under well-specified quantities and conditions.  The useof asbestos is not comparable to the controlled use of pesticides, as its use is proposed by Canada
exclusively for commercial and economic reasons.  To clarify even better the point, the parallel
should be drawn with human medicinal products which are allowed to be used under strictly
controlled conditions.  Taking Brazil's logic to its extreme, it would also suggest prohibiting human
medicinal products because asbestos is also prohibited.
Question 5:  Have substitute fibres been subject to the same close scientific scrutiny as asbestos?
Do not the relevant studies conclude that many of  the fibres cause cancer in rats and thus are
suspected carcinogens?  Does not IARC specify several of them as Class II carcinogens,
including glass fibres, rock wool and slag wool?
347. The products used as substitutes for asbestos have been the subject of scientific studies like
asbestos.  Among all the products that may be used as asbestos substitutes, no fibre has beenrecognized as a proven human carcinogen (Class I - International Cancer Research Centre), unlike
asbestos, which is a proven carcinogen.  Only ceramic fibres are classed as Class II carcinogens,
i.e. proven for animals, but they are used only in very limited and carefully controlled cases.
Question 6:  If France were to remove from the fi rst submission all reference studies that do not
distinguish chrysotile and amphibole, is it true that no studies would remain?  If some studieswould remain, how many would remain?
Question 7:  If France were to remove from the first submission all references to studies that do
not directly address the risk of current controlled use of chrysotile, isn't it true that no studies
would remain?  If some studies would remain, how many would remain?
348. Those questions of Brazil are purely rhetoric.  Brazil appears to ignore the fact that the WHO
Health Criteria 203 of 1998 (point 3 of Recommendations and Conclusions) have confirmed that:
"Exposure to chrysotile asbestos poses increased risks for asbestosis, lung cancer and mesothelioma in
a dose dependent manner.  No threshold has been identified for carcinogenic risks"…"Where safersubstitute materials are available for chrysotile, they should be considered for use"…"Some asbestoscontaining products pose particular concern and chrysotile use in those circumstances is not
recommended.  These uses include friable products with high exposure potential.  Construction
materials are of particular concern for several reas ons.  The construction industry work force is large
and measures to control asbestos are difficult to institute.  In-place building materials may also pose
risk control to those doing alterations, maintenance and demolition.  Minerals in-place have thepotential to deteriorate and create exposures".
349. It follows that the WHO, like so many other scientific publications cited in the report of
INSERM, consider that chrysotile asbestos poses similar risks and the same type of problems asregards controlled use to those posed by amphiboles asbestos.  So, all the references in the scientific
literature in the INSERM report remain valid and pertinent.
Question 8:  Does the EC not recognize that am phiboles is more toxic than chrysotile?  If so,
shouldn't the EC focus only on studies that at least attempt to distinguish the two?  If not, how
does the EC explain its position in light of th e conclusions of relevant studies, including the
INSERM report itself, concluding that amphiboles is more toxic?WT/DS135/R/Add.1
Page 105
350. Lung cancer is caused, with a comparable carcinogenic effect, by chrysotile asbestos and by
amphiboles asbestos.  Chrysotile asbestos, on the ot her hand, presents a lesser risk than amphiboles as
regards mesothelioma.  In both cases these diseases are currently untreatable and fatal, and it is no less
serious to die of lung cancer than to die of mesothelioma.
