Except where a Certificate of Origin either is not submitted when requested under § 181.22(b) of this part or is not acceptable and a corrected Certificate is not submitted or accepted as provided in § 181.22(c) of this part and except as otherwise provided in § 181.23 of this part and except in the case of a pattern of conduct provided for in § 181.76(c) of this part, Customs shall deny preferential tariff treatment on an imported good, or shall deny a post-importation claim for a refund filed under subpart D of this part, only after initiation of an origin verification under § 181.72(a) of this part which results in a determination that the imported good does not qualify as an originating good or should not be accorded such treatment for any other reason as specifically provided for elsewhere in this part.

(a) General. Subject to paragraph (e) of this section, Customs may initiate a verification in order to determine whether a good imported into the United States qualifies as an originating good for purposes of preferential tariff treatment under the NAFTA as stated on the Certificate of Origin pertaining to the good. Such a verification:

(1) May also involve a verification of the origin of a material that is used in the production of a good that is the subject of a verification under this section;

(2) May include verification of the applicable rate of duty applied to an originating good in accordance with Annex 302.2 of the NAFTA and may include a determination of whether a good is a qualifying good for purposes of Annex 703.2 of the NAFTA; and

(3) Shall be conducted only by means of one or more of the following:

(i) A verification letter which requests information from a Canadian or Mexican exporter or producer, including a Canadian or Mexican producer of a material, and which identifies the good or material that is the subject of the verification. The verification letter may be on Customs Form 28, or its electronic equivalent, or other appropriate format and may be sent:

(A) By certified or registered mail, or by any other method that produces a confirmation of receipt by the exporter or producer; or

(B) By any other method, regardless of whether it produces proof of receipt by the exporter or producer;

(ii) A written questionnaire sent to an exporter or a producer, including a producer of a material, in Canada or Mexico. The questionnaire:

(A) May be sent by certified or registered mail, or by any other method that produces a confirmation of receipt by the exporter or producer; or

(B) May be sent by any other method, regardless of whether it produces proof of receipt by the exporter or producer; and

(C) May be completed by the Canadian or Mexican exporter or producer either in the English language or in the language of the country in which that exporter or producer is located;

(iii) Visits to the premises of an exporter or a producer, including a producer of a material, in Canada or Mexico to review the types of records referred to in § 181.12 of this part and observe the facilities used in the production of the good or material; and

(iv) Any other method which results in information from a Canadian or Mexican exporter or producer, including a Canadian or Mexican producer of a material, that is relevant to the origin determination. The information so obtained may form a basis for a negative determination regarding a good (see § 181.75(b) of this part) only if the information is in writing and is signed by the exporter or producer.

(b) Applicable accounting principles. When conducting a verification of origin to which Generally Accepted Accounting Principles may be relevant, Customs will apply and accept the Generally Accepted Accounting Principles applicable in the country in which the good is produced or in which the exporter is located.

(c) Inquiries to importer not precluded. Nothing in paragraph (a) of this section shall preclude Customs from directing inquiries or requests to a U.S. importer for documents or other information regarding the imported good. If such an inquiry or request involves requesting the importer to obtain and provide written information from the exporter or producer of the good or from the producer of a material that is used in the production of the good, such information shall be requested by the importer and provided to the importer by the exporter or producer only on a voluntary basis, and a failure or refusal on the part of the importer to obtain and provide such information shall not be considered a failure of the exporter or producer to provide the information and shall not constitute a ground for denying preferential tariff treatment on the good.

(d) Failure to respond to letter or questionnaire—(1) Nonresponse to initial letter or questionnaire. If the exporter or producer, including a producer of a material, fails to respond to a verification letter or questionnaire sent under paragraph (a)(2)(i) or (a)(2)(ii) of this section within 30 calendar days from the date on which the letter or questionnaire was sent, or such longer period as may be specified in the letter or questionnaire, Customs shall send a follow-up verification letter or questionnaire to that exporter or producer. The follow-up letter or questionnaire:

(i) Except where the verification letter or questionnaire only involved the origin of a material used in the production of a good and was sent to the producer of the material, may include the written determination referred to in § 181.75 of this part, provided that the information specified in paragraph (b) of that section is also included; and

(ii) Shall be sent:

(A) By certified or registered mail, or by any other method that produces a confirmation of receipt by the exporter or producer, if so requested by the customs administration of Canada or Mexico from which the good was exported; or

(B) By any method, if no request under paragraph (d)(1)(ii)(A) of this section has been made by the Canadian or Mexican customs administration.

(2) Nonresponse to follow-up letter or questionnaire—(i) Producer of a material. If a producer of a material fails to respond to a follow-up verification letter or questionnaire sent under paragraph (d)(1) of this section, Customs may consider the material to be non-originating for purposes of determining whether the good to which that material relates is an originating good.

(ii) Exporter or producer of a good. If the exporter or producer of a good fails to respond to a follow-up verification letter or questionnaire sent under paragraph (d)(1) of this section, Customs may consider the good to be non-originating and consequently may deny preferential tariff treatment on the good as follows:

(A) If the follow-up letter or questionnaire included a written determination as provided for in paragraph (d)(1)(i) of this section and the exporter or producer fails to respond to the follow-up letter or questionnaire within 30 calendar days or such longer period as specified therein:

(1) From the date on which the follow-up letter or questionnaire and written determination were received by the exporter or producer, if sent pursuant to paragraph (d)(1)(ii)(A) of this section; or

(2) From the date on which the follow-up letter or questionnaire and written determination were either received by the exporter or producer or sent by Customs, if sent in accordance with paragraph (d)(1)(ii)(B) of this section; or

(B) Provided that the procedures set forth in §§ 181.75 and 181.76 of this part are followed, if the follow-up letter or questionnaire does not include a written determination as provided for in paragraph (d)(1)(i) of this section and the exporter or producer fails to respond to the follow-up letter or questionnaire within 30 calendar days or such longer period as specified in the letter or questionnaire:

(1) From the date on which the follow-up letter or questionnaire was received by the exporter or producer, if sent pursuant to paragraph (d)(1)(ii)(A) of this section; or

(2) From the date on which the follow-up letter or questionnaire was either received by the exporter or producer or sent by Customs, if sent in accordance with paragraph (d)(1)(ii)(B) of this section.

(e) Calculation of regional value content under net cost method—(1) General. Where a Canadian or Mexican producer of a good elects to calculate the regional value content of a good under the net cost method as set forth in General Note 12, HTSUS, and in the appendix to this part, Customs may not, during the time period over which that net cost is calculated, conduct a verification under § 181.72(a) of this part with respect to the regional value content of that good.

(2) Cost submission for motor vehicles. Where, pursuant to General Note 12, HTSUS, and the appendix to this part, a Canadian or Mexican producer of a light duty vehicle or heavy duty vehicle, as defined in the appendix to this part, elects to average its regional value content calculation over its fiscal year, Customs may request, in writing, that the producer provide a cost submission reflecting the actual costs incurred in the production of the category of motor vehicles for which the election was made. Such a written request shall constitute a verification letter under paragraph (a)(2)(i) of this section, and the requested cost submission shall be submitted to Customs within 180 calendar days after the close of the producer's fiscal year or within 60 days from the date on which the request was made, whichever is later.

(a) Written notification required. Prior to conducting a verification visit in Canada or Mexico pursuant to § 181.72(a)(2)(iii) of this part, Customs shall give written notification of the intention to conduct the visit. Such notification shall be delivered:

(1) By certified or registered mail, or by any other method that produces a confirmation of receipt, to the address of the Canadian or Mexican exporter or producer whose premises are to be visited;

(2) To the customs administration of the country in which the visit is to occur; and

(3) If requested by the country in which the visit is to occur, to the embassy of that country located in the United States.

(b) Contents of notification. The notification referred to in paragraph (a) of this section shall include:

(1) The identity of the Customs office and officer issuing the notification;

(2) The name of the Canadian or Mexican exporter or producer of the good, or producer of the material, whose premises are to be visited;

(3) The date and place of the proposed verification visit;

(4) The object and scope of the proposed verification visit, including specific reference to the good or material that is the subject of the verification;

(5) The names and titles of the Customs officers performing the proposed verification visit;

(6) The legal authority for the proposed verification visit; and

(7) A request that the Canadian or Mexican exporter or producer of the good, or producer of the material, provide its written consent for the proposed verification visit.

(a) Written consent required. Prior to conducting a verification visit in Canada or Mexico pursuant to § 181.72(a)(3)(iii) of this part, CBP shall obtain the written consent of the Canadian or Mexican exporter or producer of the good or producer of the material whose premises are to be visited.

(b) Written consent procedures. The written consent provided for in paragraph (a) of this section shall be delivered by certified or registered mail, or by any other method that generates a reliable receipt, to the CBP officer who gave the notification provided for in § 181.73 of this part.

(c) Failure to provide written consent or to cooperate or to maintain records. Except as otherwise provided in paragraph (d) of this section, where a Canadian or Mexican exporter or producer of a good, or a Canadian or Mexican producer of a material, has not given its written consent to a proposed verification visit within 30 calendar days of receipt of notification pursuant to § 181.73 of this part, CBP may deny preferential tariff treatment to that good, or for purposes of determining whether a good is an originating good may consider as non-originating that material, that would have been the subject of the visit, provided that, as regards the good, notice of intent to deny such treatment is given to that exporter or producer of the good and to the U.S. importer thereof prior to taking such action. A failure on the part of the Canadian or Mexican exporter or producer of a good, or on the part of the Canadian or Mexican producer of a material, to maintain records or provide access to such records or otherwise cooperate during the verification visit shall mean that the verification visit never took place and may be treated by CBP in the same manner as a failure to give written consent to a verification visit. However, in the case of a Canadian or Mexican producer of a good who is found during a verification visit to have not maintained records in accordance with the Generally Accepted Accounting Principles applied in the producer's country, CBP may deny preferential tariff treatment on the good based solely on a failure to so maintain those records only if the producer does not conform the records to those Principles within 60 calendar days after CBP informs the producer in writing of that failure.

(d) Postponement of visit in Canada or Mexico. Following receipt of the notification provided for in § 181.73 of this part, the Canadian or Mexican customs administration may, within 15 calendar days of receipt of the notification, postpone the proposed verification visit for a period not exceeding 60 calendar days from the date of such receipt by providing written notice of the postponement to the CBP officer who issued the notification of the verification visit, unless a longer period is requested and agreed to by CBP. Such a postponement shall not constitute a failure to provide written consent within the meaning of paragraph (c) of this section and shall not otherwise by itself constitute a valid basis upon which CBP may:

(1) Consider a material that is used in the production of a good to be a non-originating material; or

(2) Deny preferential tariff treatment to a good.

(e) Verification visits within the United States—(1) Notification and consent procedure. When the Canadian or Mexican customs administration intends to conduct a verification visit in the United States, notification of such intent will be given, and consent will be required, as provided for under Article 506 of the NAFTA. For purposes of the required notification to CBP, such notification shall be sent to U.S. Customs and Border Protection, Office of International Trade, Commercial Targeting and Enforcement, 1300 Pennsylvania Ave., NW., Washington, DC 20229.

(2) Postponement of visit. Following receipt of notification from the Canadian or Mexican customs administration of its intention to conduct a verification visit in the United States, CBP may, within 15 calendar days of receipt of the notification, postpone the proposed verification visit for a period not exceeding 60 calendar days from the date of such receipt by providing written notice of the postponement to the Canadian or Mexican customs administration.

(3) Designation of observers. A U.S. exporter or producer, including a producer of a material, whose good or material is the subject of a verification visit by the Canadian or Mexican customs administration shall be allowed to designate two observers to be present during the visit, subject to the following conditions:

(i) The U.S. exporter or producer shall not be required to designate observers;

(ii) There shall be no restriction on the class of persons that may be designated as observers by the U.S. exporter or producer;

(iii) The observers to be present are designated in the written consent to the proposed visit or subsequent thereto;

(iv) The observers do not participate in the verification visit in a manner other than as passive observers;

(v) The presence of observers shall in no way affect the right to have legal counsel or other advisors present during the visit;

(vi) There shall be no obligation on the part of the United States government or on the part of the Canadian or Mexican government to designate observers from its staff, even when the U.S. exporter or producer fails to, or specifically declines to, designate observers; and

(vii) The failure of the U.S. exporter or producer to designate observers shall not result in the postponement of the visit.

(a) General. Except in the case of a pattern of conduct within the meaning of § 181.76(c) of this part, following receipt and analysis of the results of an origin verification initiated under § 181.72(a) of this part in regard to a good imported into the United States and prior to denying preferential tariff treatment on the import transaction which gave rise to the origin verification, Customs shall provide the exporter or producer whose good is the subject of the verification with a written determination of whether the good qualifies as an originating good. Subject to paragraph (b) of this section, the written origin determination shall be sent within 60 calendar days after conclusion of the origin verification process, unless circumstances require additional time, and shall set forth:

(1) A description of the good that was the subject of the verification together with the identifying numbers and dates of the export and import documents pertaining to the good;

(2) Subject to the provisions of § 181.131 of this part and except in the case of a negative origin determination where specific findings of fact cannot be made because of a failure to respond to a follow-up verification letter or questionnaire sent under § 181.72 of this part, a statement setting forth the findings of fact made in connection with the verification and upon which the determination is based; and

(3) With specific reference to the rules applicable to originating goods as set forth in General Note 12, HTSUS, and in the appendix to this part, the legal basis for the determination.

(b) Negative origin determinations. If Customs determines, as a result of an origin verification initiated under § 181.72(a) of this part, that the good which is the subject of the verification does not qualify as an originating good, the written determination required under paragraph (a) of this section:

(1) Shall be sent by certified or registered mail, or by any other method that produces a confirmation of receipt by the exporter or producer, if so requested by the customs administration of Canada or Mexico from which the good was exported; and

(2) Shall, in addition to the information specified in paragraph (a) of this section, set forth the following:

(i) A notice of intent to deny preferential tariff treatment on the good which is the subject of the determination;

(ii) The specific date after which preferential tariff treatment will be denied, as established in accordance with § 181.76(a)(1) of this part;

(iii) The period, established in accordance with § 181.76(a)(1) of this part, during which the exporter or producer of the good may provide written comments or additional information regarding the determination; and

(iv) A statement advising the exporter or producer of the right to file a protest under 19 U.S.C. 1514 and part 174 of this chapter:

(A) Within 90 days after notice of liquidation is provided pursuant to part 159 of this chapter; or

(B) In cases where the negative origin determination does not result in a liquidation, within 90 days after the date of issuance of the written determination.

(a) General. Except as otherwise provided in this section, an origin determination may be applied upon issuance of the determination under § 181.75 of this part.

(b) Negative origin determinations. In the case of a negative origin determination issued under § 181.75(b) of this part:

(1) The date on which preferential tariff treatment may be denied shall be no earlier than 30 calendar days from the date on which:

(i) Receipt of the written determination by the exporter or producer is confirmed, if a request under § 181.75(b)(1) of this part has been made; or

(ii) The written determination is sent by Customs, if no request under § 181.75(b)(1) of this part has been made; and

(2) Before denying preferential tariff treatment, Customs shall take into account any comments or additional information provided by the exporter or producer during the period established in accordance with paragraph (b)(1) of this section.

(c) Cases involving a pattern of conduct. Where multiple origin verifications initiated under § 181.72(a) of this part indicate a pattern of conduct by an exporter or producer involving false or unsupported representations on Certificates of Origin that a good imported into the United States qualifies as an originating good, Customs may deny subsequent claims for preferential tariff treatment on identical goods exported or produced by such person until that person establishes compliance with the rules applicable to originating goods as set forth in General Note 12, HTSUS, and in this part, provided that advance written notice of the intent to deny such claims is given to the importer. For purposes of this paragraph, a “pattern of conduct” means repeated instances of false or unsupported representations by an exporter or producer as established by Customs on the basis of not fewer than two origin verifications of two or more importations of the good that result in the issuance of not fewer than two written determinations issued to that exporter or producer pursuant to § 181.75 of this part which conclude, as a finding of fact, that Certificates of Origin completed and signed by that exporter or producer with respect to identical goods contain false or unsupported representations.

(d) Differing determinations. Where Customs determines, either as a result of an origin verification initiated under § 181.72(a) of this part or under any other circumstance, that a certain good imported into the United States does not qualify as an originating good based on a tariff classification or a value applied in the United States to one or more materials used in the production of the good, including a material used in the production of another material that is used in the production of the good, which differs from the tariff classification or value applied to the materials by the country from which the good was exported, the Customs determination shall not become effective until Customs provides written notification thereof both to the U.S. importer of the good and to the person who completed and signed the Certificate of Origin upon which the claim for preferential tariff treatment for the good was based.

(e) Applicability of a determination to prior importations. Customs shall not apply a determination made under paragraph (d) of this section to an importation made before the effective date of the determination if, prior to notification of the determination, the customs administration of the country from which the good was exported either issued an advance ruling under Article 509 of the NAFTA or any other ruling on the tariff classification or on the value of such materials, or gave consistent treatment to the entry of the materials under the tariff classification or value at issue, on which a person is entitled to rely and on which that person did in fact rely. For purposes of this paragraph, the person who received notification of the determination shall demonstrate to the satisfaction of Customs, in writing within 30 calendar days of receipt of the notification, that the conditions set forth herein have been met. For purposes of this paragraph:

(1) A “ruling” on which a person is entitled to rely in the case of Canada must be issued pursuant to section 43.1(1) of the Customs Act (Advance Rulings) or in accordance with Departmental Memorandum 11-11-1 (National Customs Rulings) and in the case of Mexico must be issued pursuant to Article 34 of the Codigo Fiscal de la Federacion and pursuant to Article 30 of the Ley Aduanera or the applicable provision of Mexican law related to advance rulings under Article 509 of the NAFTA; and

(2) “Consistent treatment” means the established application by the Canadian or Mexican customs administration that can be substantiated by the continued acceptance by the customs administration of the tariff classification or value of identical materials on importations of the materials into Canada or Mexico by the same importer over a period of not less than two years immediately prior to the date of signature of the Certificate of Origin for the good that is the subject of the determination referred to in paragraph (d) of this section, provided that with regard to those importations:

(i) The tariff classification or value of the materials was not the subject of a verification, review or appeal by that customs administration on the date of the determination under paragraph (d) of this section; and

(ii) The materials had not been accorded a different tariff classification or value by one or more district, regional or local offices of that customs administration on the date of the determination under paragraph (d) of this section.

(f) Detrimental reliance. If Customs proposes to deny preferential tariff treatment to a good pursuant to a determination made under paragraph (d) of this section, Customs shall postpone the application of the determination for a period not exceeding 90 calendar days from the date of issuance of the determination where the U.S. importer of the good, or the person who completed and signed the Certificate of Origin upon which the claim for preferential tariff treatment for the good was based, demonstrates to the satisfaction of Customs that it has relied in good faith to its detriment on the tariff classification or value applied to such materials by the customs administration of the country from which the good was exported.
