(1) General. Except as otherwise provided in paragraph (a)(2) of this section, Customs will, within 120 calendar days of receipt of a request, including any required information supplemental thereto, issue an advance ruling letter in the English language setting forth the position of Customs and the reasons therefor with respect to a specifically described Customs transaction whenever a request for such an advance ruling is submitted in accordance with the provisions of this subpart and it is in the sound administration of the NAFTA provisions to do so. Otherwise, a request for an advance ruling will be answered by an information letter or, in those situations in which general information is likely to be of little or no value, by a letter stating that no advance ruling can be issued. In the course of evaluating the advance ruling request Customs may solicit supplemental information from the person requesting the advance ruling. The submission of supplemental information will extend the time for response. The time for response will also be extended if it is necessary to obtain information from other government agencies or in the form of a laboratory analysis.

(2) Submission of NAFTA advance ruling letters to field offices. Any importer engaging in a NAFTA transaction with respect to which an advance ruling letter has been issued under this subpart either must ensure that a copy of the advance ruling letter is attached to the documents filed with the appropriate Customs office in connection with that transaction or must otherwise indicate with the information filed for that transaction that an advance ruling has been received. Any person receiving an advance ruling stating Customs determination must set forth such determination in the documents or information filed in connection with any subsequent entry of that merchandise; failure to do so may result in a rejection of the entry and the imposition of such penalties as may be appropriate. An advance ruling received after the filing of such documents or information must immediately be brought to the attention of the appropriate Customs field office.

(3) Disclosure of NAFTA advance ruling letters. No part of the advance ruling letter, including names, addresses, or information relating to the business transactions of private parties, shall be deemed to constitute privileged or confidential commercial or financial information or trade secrets exempt from disclosure pursuant to the Freedom of Information Act, as amended (5 U.S.C. 552), and part 103 of this chapter, or shall be deemed to be subject to the confidentiality principle set forth in § 181.121 of this part, unless, as provided in § 181.93(b)(7) of this part, the information claimed to be exempt from disclosure is clearly identified and a valid basis for nondisclosure is set forth. Before the issuance of the advance ruling letter, the person submitting the advance ruling request will be notified of any decision adverse to his request for nondisclosure and will, upon written request to Customs within 10 working days of the date of notification, be permitted to withdraw the advance ruling request. If in the opinion of Customs an impasse exists on the issue of confidentiality and the person who submitted the advance ruling request does not withdraw the request, Customs will decline to issue the advance ruling. All advance ruling letters issued by Customs will be available, upon written request, for inspection and copying by any person (with any portions determined to be exempt from disclosure deleted).

(4) Penalties for misrepresented or omitted material facts or for noncompliance. If Customs determines that an issued advance ruling was based on incorrect information, the person to whom the advance ruling was issued may be subject to appropriate penalties unless that person demonstrates that he used reasonable care and acted in good faith in presenting the facts and circumstances on which the advance ruling was based. In addition, Customs may apply such measures as the circumstances may warrant in a case where a person to whom an advance ruling was issued has failed to act in accordance with the terms and conditions of the advance ruling.
