3. TARIFF CLASSIFICATION:WRG requires the correct classification under the Harmonized Tariff Schedule of theUnited States (“HTSUS”) to the 10th digit be incorporated into the Commercial Invoice
for each product shipped to WRG. WRG will verify that the correct HTSUS
classification is used for all products imported by WRG. WRG personnel will analyze
the products from the vendor and assign a verified HTSUS classification, which will thenbe incorporated into an HTSUS database maintained by WRG. As requested by WRG,
the vendor must also supply detailed product documentation (technical specifications,datasheets, marketing materials, etc.) necessary for WRG to complete the classification
analysis for the product in question.
These verified HTSUS classifications will be provided by WRG to the vendor for theirproducts. This verified HTSUS classification must then be incorporated into the invoice
for each product and used for all shipments to WRG. On an annual basis, the vendor
must submit a full listing of all products sold to WRG. This listing will be utilized by

4

WRG to ensure that the HTSUS classification database is current and contains verified
HTSUS classifications for all products imported by WRG.
Throughout the year, new products may be sourced by WRG from the vendor. Since
these new products would not exist in WRG’s HTSUS classification database, aclassification analysis must be conducted. For any new product to be shipped to WRG,
the vendor must submit a full description of the product as well as any supporting
documentation necessary to complete the classification analysis. Once the verified
HTSUS classification is determined, it will be incorporated into WRG’s classification
database and provided to the vendor for use on the invoice.
As discussed above, the vendor is not to assign the HTSUS classification. The vendor
must obtain a verified HTSUS classification for its product from WRG before shipping
any products. If any HTSUS classification data is missing or unclear, the vendor is
instructed to contact WRG according to the information provided in the Contact andNotification Information, section 1.
Classification of Samples:
WRG frequently receives product samples sent to the US for testing, evaluation, etc.
The above HTSUS classification review procedures also apply to any sample shipped to
WRG. The proper HTSUS classification of all samples must be included on the invoiceaccompanying the sample item(s). WRG must determine the correct HTSUS
classification of any sample prior to shipment. The vendor must provide a complete
description of the sample item, as well as any detailed product information requested by
WRG. Once the correct HTSUS classification is determined by WRG, the information
will be provided to the vendor for inclusion on the invoice. Please see Valuation,section 4, for other requirements specific to the shipment of samples to WRG.
Classification of U.S. Goods Returned:
For US origin goods shipped back to the US, use of the HTSUS heading 9801 provision
is not permitted without written authorization from WRG. Please see the U.S. Goods
Returned, section 7 below).
4. CUSTOMS VALUATION:
WRG typically uses transaction value as the method for appraisement for its imports
into the US. Transaction value is defined as “the price paid or payable” of themerchandise when sold for export to the US. As a result, the value on the commercial
invoice should always represent the amount being billed to WRG (please note exception
in the Valuation of Samples section below).
Additions to the Price Paid or Payable:5In addition to the “price paid or payable”, certain additions to transaction value must be
captured and included on the commercial invoice (if applicable). If the vendor believes
that any of the following may exist with respect to goods shipped to WRG, the vendor
must contact the appropriate personnel at WRG to determine the appropriate value toinclude on the commercial invoice and declare to Customs.
Assists are the following items, if WRG provides them to the vendor free of charge or ata reduced cost (i.e., not sold to the vendor) for use in producing goods subsequently
imported into the US. Information on any potential assists must be provided to thecontact personnel at WRG indicated in section 1 so that they can conduct an analysis todetermine if there should be an addition to the transaction value. Common assists
include the following:• Materials, components, parts, and similar items that are incorporated into theimported product• Tool, dies, molds, and similar items used in producing the imported product• Product consumed in producing the imported product• Engineering, development, artwork, design work, plans and/or sketches that areundertaken outside the US
Items on the assist list can also represent additions to transaction value even if they are
not provided directly to the vendor by WRG. These additions to value arise fromindirect payments, which would occur if the vendor acquires any of the assist items
and invoices WRG separately for the acquisition cost. Similarly, an indirect payment
could occur if WRG is invoiced by a third party for any assist item that is provided to thevendor. The vendor must provide any available information on indirect payments to theindicated contact personnel at WRG so that they can conduct an analysis to determine
if there should be an addition to transaction value.
Packing Costs (if not already included in the price paid or payable). The cost of
packing merchandise for export to the US (including the cost of all containers,
coverings, materials, and labor associated with packing) must be included in the priceactually paid or payable in order for the amount to be considered a valid transaction
value amount. The vendor must ensure that all applicable packing costs areincorporated into the invoice value charged to WRG. If the packing costs are notcaptured in the invoice value, the vendor must provide the cost information to thecontact personnel at WRG indicated in section 1 so that they can determine whether
there needs to be an adjustment to the transaction value of the shipment in question.
Selling Commissions – A selling commission is any commission paid to an agent of
the seller (and incurred by the buyer) with respect to the imported merchandise. Sellingcommissions are typically included as part of the transaction value of the imported
merchandise. Information on any selling commission must be provided to the contact
personnel at WRG indicated in section 1 so that they can conduct an analysis todetermine if the commission should be included as part of the transaction value.
Although they may not be dutiable, the vendor must report any information related tobuying commissions to WRG. Buying commissions are paid to an agent of the buyer forservices performed in relation to the purchase of imported goods.

6Royalties or Licensing Fees - The value of any royalty or license fee paid as acondition of sale of the imported product for export to the US. may be dutiable. The
vendor must provide information on any royalties or license fees to the contact
personnel at WRG indicated in section 1 who will in turn conduct an analysis todetermine if the royalties or license fees should be included in the transaction value.
Proceeds of a Subsequent Resale – The value of any proceeds paid to the seller
directly or indirectly from the sale, disposal, or use of the imported merchandise isdutiable and must be added to the price paid or payable. The vendor must provide
information on any proceeds of a subsequent resale to the contact personnel at WRG
indicated in section 1, who will conduct an analysis to determine if there needs to be an
adjustment to transaction value.
Foreign Inland Freight – If the goods were not shipped on a through Bill of Lading, thecost of freight from the vendor to the foreign port of export must be added to the pricepaid or payable. The vendor must provide complete information on the costs of foreigninland freight, and itemize such costs on the invoice to WRG. Depending on the termsof sale, the WRG personnel (see 1) would then determine if the cost of foreign inlandfreight should be incorporated into the dutiable value of the shipment in question.
Deductions from the Price Paid or Payable:
International freight and insurance charges for imported goods can be deducted fromthe price paid or payable. If international freight and insurance are not incorporated into
the price paid or payable by WRG, then no action is required by the vendor (thissituation would typically occur for shipments with terms of sale of Ex-Works or Free On
Board (FOB), Free Along Side (FAS), or Free Carrier, (FCA)). However, if international
freight and insurance are incorporated into the price paid or payable (i.e., shipmentswith terms of sale other than Ex-Works, FOB, FAS, or FCA), WRG can only deduct
these charges from the entered value if they:• are itemized on the commercial invoice• represent actual charges (estimated charges are not acceptable).
As a result, the vendor must itemize international freight and insurance on its invoices to
WRG for any shipments with terms of sale other than Ex-Works, FOB, FAS, or FCA. If
possible, the vendor should always include the actual international freight and insurance
amounts to be charged. If the amounts on the invoices represent estimated charges,
the vendor must notify the indicated contact personnel at WRG of this fact at the time
the shipment is made. Once available, the vendor must immediately provide the actualinternational freight and insurance charges to the contact personnel at WRG indicatedin section 1. The WRG personnel will then make the necessary adjustments to thetransaction value of the shipment in question.
Valuation of Samples:

7

WRG frequently receives product samples sent to the US. for testing, evaluation, etc.
Even though the sample is likely sent to WRG free of charge, it is imperative that the
sample be properly valued. This requires that the sample value should reflect actual
cost to acquire or produce the product, or the normal price that would have been
charged to WRG for the product (i.e., the normal retail cost of the product plus a
reasonable profit by the vendor). Once the proper sample value has been determined,
the value should be incorporated into the invoice with the following language:“Sample, Not for Resale – Value for Customs Purposes Only $___________.”
See Tariff Classification, section 3, for other requirements specific to the shipment ofsamples to WRG.
5. COUNTRY OF ORIGIN / MARKING:In general, every article of foreign origin entering the US. must be legibly marked with
the English name of the country of origin. Additionally, the country of origin of the
product must be declared on the commercial invoice.
Country of Origin Determination:
Goods imported by WRG under a special trade program (e.g., NAFTA, GSP, etc.) will
have their own unique country of origin and qualification requirements. Please see
Special Trade Programs, section 6, for more information.
For goods imported without the benefit of a special trade program, the country of origin
determination is conducted as follows. For products made wholly ofcomponents/materials from a single country, the country of origin is the country of
manufacture or growth of the product in question. For products manufactured with
imported components/materials, the country of origin is the country in which the final
product underwent a “substantial transformation” to become a new article of commerce.
The criteria-giving rise to substantial transformation can vary from industry to industry
and product to product. As a result, the vendor must contact WRG if there is any
uncertainty over the proper country of origin determination for a product to be shipped to
WRG.
Marking Requirements:
Articles and containers imported into the U.S. must be clearly marked in English
according to the following guidelines:
Scope: Every article and/or its container (excluding goods of US origin) that is received
by the ultimate purchaser in the US must be marked with the country of origin.
Location: The markings must be conspicuous, read without strain and visible during
casual handling.

8Legibility: The markings must be clear, of adequate size, easily read by persons ofnormal vision.
Permanence: The marking must be indelible and as permanent as the product allows.
Language: All markings must be in English.
Statement: The markings must consist of the language “Made in (country)” or “Productof (country)”
Exemptions from the above marking requirements exist for certain imported articles andcircumstances. These exemptions from marking requirements apply to the following:•

Articles incapable of being marked (including bulk products and crude
substances).

•

Products of US origin that are being returned to the US.

•

Articles imported for use by the importer and not intended for sale in theirimported or any other form.

•

Articles imported into the US for further processing by the importer or for its
account, through which any marking would be obliterated, destroyed, or
permanently concealed.

•“Usual containers” from a NAFTA country (i.e., the U.S., Canada, or Mexico). An“usual container” is the container in which an imported article will ordinarily reachthe ultimate purchaser. Usual containers, which are goods of a NAFTA country,
are not required to be marked with their own origin, whether or not filled.

6. SPECIAL TRADE PROGRAMS:
Goods shipped to WRG from Canada or Mexico may qualify for duty-free treatment
under the North American Free Trade Agreement (“NAFTA”). Additionally, some WRG
imports may qualify for duty-free treatment under the Generalized System ofPreferences (“GSP”). Specific rules exist for determining whether a product qualifies forthe duty-free treatment under both NAFTA and GSP. The vendor is responsible for
conducting the necessary analysis to qualify the products under NAFTA and GSP, if
applicable. However, the vendor is not to indicate that the goods qualify for NAFTA or
GSP without first obtaining approval from the responsible officials from WRG. In
particular, the vendor is responsible for providing all information and declarations
necessary for qualifying the goods under NAFTA or GSP to WRG for review. Once
reviewed, WRG will indicate if it agrees that the goods are qualified for NAFTA or GSP.
The vendor may not claim NAFTA or GSP on products shipped to WRG without thisexplicit approval from WRG. All claims for NAFTA or GSP by vendors are subject toaudit by WRG. Information on the qualification requirements for NAFTA and GSP areprovided below.
North American Free Trade Agreement (NAFTA):

9

Many products imported by WRG obtain duty-free treatment under NAFTA. NAFTA
eliminates or reduces duties imposed on goods traded between the member countries,
provided that the goods qualify as "originating" within the NAFTA territory (i.e., the US,
Canada and Mexico).
It is imperative that assumptions are not made regarding origin being US, Canada and
Mexico. Vendors are required to properly qualify their goods under NAFTA andcomplete a formal NAFTA Certificate of Origin for all qualifying products sourced by
WRG. (A sample NAFTA Certificate of Origin is attached to these instructions as
Appendix A). The NAFTA Certificate of Origin is the document used to certify that the
goods being exported are "originating". The original NAFTA Certificate of Origin must
be completed and signed by the exporter, and be maintained at WRG Import
Departments. Vendors are required to recertify originating NAFTA products on a yearlybasis.
It is critical that the NAFTA Certificates of Origin be accurately prepared. Key elementsof the NAFTA Certificates of Origin that must be addressed are discussed below:
The NAFTA certificates of origin must be signed and dated by an appropriate
representative of the vendor.
The NAFTA certificates of origin must include an accurate description of each product(not just a part number or internal identifier).
The NAFTA certificates of origin must include the correct US tariff classification of eachproduct according to the HTSUS.
The correct preference criterion – A, B, C or D – must be used for each product. These
preference criteria indicate the manner in which a product qualifies for NAFTA
preferential treatment, as indicated below:
Criterion A – This preference criterion is only used for goods that are “wholly obtained or
produced entirely” in a NAFTA territory. Goods that can qualify for NAFTA under thiscriterion are generally limited to minerals and agricultural products that are mined orgrown entirely within a NAFTA country and will therefore not normally be used forgoods imported by WRG.
Criterion B – This preference criterion is used for goods that satisfy a specific rule oforigin as defined in the HTSUS. Each product classification in the HTSUS will have its
own qualification requirements, which will consist of a “tariff shift” and/or regional value
content (RVC) calculation. Goods that require a tariff shift can qualify provided thateach of the non-originating materials used in the production of the product undergoes
an applicable change in tariff classification as the result of production occurring
entirely in the territory of the NAFTA parties. Goods that require an RVC calculation
can qualify provided that the value of the NAFTA originating materials/components
meets a specified threshold. Many goods imported by WRG will qualify for NAFTA
under this preference criterion.
Criterion C – This preference criterion is used for goods that are produced entirely
within the territory of a NAFTA country exclusively from originating
materials/components. Goods are produced entirely in the territory of one or more of
the NAFTA countries, but one or more of the non-originating materials used in the10

production of the good which is provided for as "parts" under the HTSUS does notundergo a change in tariff classification. Some goods imported by WRG could qualify
for NAFTA under this preference criterion.
Criterion D – This preference criterion is only used in limited circumstances for products
where the RVC calculation for non-originating materials/components has been met, but
the materials/components do not undergo a tariff shift because: a) the goods areimported into a NAFTA country in an unassembled or disassembled form but classified
as an assembled good, or b) the goods are produced using materials imported into a
NAFTA country that are provided for as parts according to the Harmonized System, andthose parts are classified in the same subheading or undivided heading as the finishedgoods. This preference criterion will not likely be used for goods imported by WRG.
Generalized System of Preferences (GSP):
Some products imported by WRG obtain duty-free treatment under GSP. GSP is usedby the US and other countries to help certain developing nations improve their financial
or economic condition through exports. It provides for the duty-free importation of awide range of products from beneficiary countries, as designated by the President of the
US. Each good eligible for GSP is designated in the HTSUS under its tariffclassification. Once it has been determined that good(s) to be imported are eligible for
GSP, a number of qualification requirements must be met as discussed below:
The origin of the product must be a designated beneficiary country, as specified in the
HTSUS for that product’s classification.
The goods must be imported directly from the beneficiary country, and cannot enter thecommerce of another country before reaching the US.
The goods must be deemed a product of the beneficiary country in question. If the
product contains materials/components from a non-beneficiary country, this requiresthat the sum of the value materials/components originating in a beneficiary country plus
the “direct cost of processing operations” performed in a beneficiary country is not lessthan 35% of the appraised value of the final product when imported into the U.S. The
direct cost of processing includes all labor, quality control, engineering, and testing
associated with the production of the final product.
The vendor must complete a statement attesting to the fact that the goods meet theabove-mentioned criteria. This attestation must be included with each import shipment.
If the product contains materials/components from a non-beneficiary country, a GSP
Declaration must be completed that incorporates the following information for each
imported product:• a description of the final product;• a description of the processing operations undertaken in the beneficiary country;• a breakdown of the direct cost of processing operations undertaken in thebeneficiary country;• a description of each of the material/component, the production process for eachmaterial/component, and the country of origin of each material/component; and• a breakdown of the cost of each of the materials/components.

11

7. U.S. GOODS RETURNED:WRG utilizes special provisions in the HTSUS for goods of US origin that are exported
and subsequently returned to the US. These special provisions, under HTSUS 9801.00(U.S. Goods Returned) allow for the duty-free entry of products of US origin if they were
not advanced in value or improved in condition while abroad.
The vendor is not to indicate that the goods qualify as U.S. Goods Returned under
HTSUS 9801 without first obtaining approval from the responsible officials from WRG.
In particular, the vendor is responsible for providing all information and declarations
necessary for qualifying the goods under HTSUS 9801. Once reviewed, WRG will
indicate if it agrees that the goods are qualified as U.S. goods returned. The vendor
may not classify products shipped to WRG as HTSUS 9801 without this explicit
approval from WRG. All uses of HTSUS 9801 by vendors are subject to audit by WRG.
There are specific criteria that must be met for a product to qualify for duty-freetreatment under HTSUS 9801, as well as certain documentation requirements including
a Foreign Shipper’s Declaration that must be provided by the vendor. Specifically, a
returned product qualifies for HTSUS 9801 only if it satisfies each of the following
qualification criteria and documentation requirements:• The product must be of US origin.
• WRG will produce or obtain (in the case of products purchased from third parties)
a Manufacturer’s Affidavit (or NAFTA Certificate of Origin) to verify the US origin
claim for the product in question.
• The product must not have been advanced in value or improved in condition by
any process of manufacture or other means while abroad (sorting, separating by
grade, packing, etc., are allowed as they are not considered to advance the valueof the US item itself).
The vendor must prepare a Foreign Shipper's Declaration for any product qualifying
as HTSUS 9801.00 and valued at over US$2,000. The Declaration must accompany
the import documentation, and must be signed and dated by an appropriate official fromthe vendor and attest to the fact that the products were not advanced in value or
improved in condition abroad. For each qualifying products, the Declaration must also
include a description of each of the qualifying products, the quantity of each productbeing returned, and the value of each product being returned. A sample declaration is
attached at the back of the instructions in Appendix B. The product must have beenpreviously exported from the US. WRG will supply proof of export as needed, throughan export invoice, bill of lading, or other commercial documentation. The product must
not have been the subject of a drawback claim related to the export. The product must
not have been manufactured in a US bonded warehouse. The product must not havebeen previously entered into the US under a Temporary Importation Bond, HTSUS
9813.00.05.

8. Wood Packing Material:
The statutory requirements of 7 C.F.R. §319.40-3 mandate that regulated WPM – suchas, crates, boxes, and pieces of wood used to support or brace cargo – being imported
into the United States shall be heat treated or fumigated with methyl bromide inaccordance with EPA label instructions and include a mark that certifies the woodcompleted the required treatment under the “Guidelines for Regulating Wood Packing
Material in International Trade,” ISPM 15 of the International Standards of Phytosanitary
Measures (ISPM) and any associated amendments, revisions or exemptions identified
by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service(APHIS).
The regulation (7 C.F.R. §319.40-3) requires that WPM display a visible, legible, andpermanent mark certifying treatment. The mark must be a legible and permanent markthat indicates that the article has been subjected to the approved measure and include
the following elements:•

The International Plant Protection Convention (IPPC) logo;•

The ISO two-letter country code for the country that produced the wood packing
material followed by a unique number code;•

The unique number code is assigned by the country’s National Plant Protection
Organization (NPPO) to the producer of the wood packaging material, who is
responsible for ensuring appropriate wood is used and properly marked.
Therefore, this code allows a trace back to the facility that treated and stamped
the WPM; and•An abbreviation that discloses the type of treatment (HT for heat treatment or MB
for methyl bromide fumigation; Guatemala is approved to use TT in place of HT
or BM in place of MB).
