§177.9. Effect of ruling letters.

Generally. Each ruling letter is issued on the assumption that all of the information furnished in connection with the ruling request and incorporated in the ruling letter, either directly, by reference, or by implication, is accurate and complete in every material respect. The application of a ruling letter by a Customs Service field office to the transaction to which it is purported to relate is subject to the verification of the facts incorporated in the ruling letter, a comparison of the transaction described therein to the actual transaction, and the satisfaction of any conditions on which the ruling was based. If, in the opinion of any Customs Service field office by whom the transaction is under consideration or review, the ruling letter should be modified or revoked, the findings and recommendations of that office will be forwarded to the Headquarters Office for consideration, as provided in § 177.11(b)(1)(i), prior to any final disposition with respect to the transaction by that office. Otherwise, if the transaction described in the ruling letter and the actual transaction are the same, and any and all conditions set forth in the ruling letter have been satisfied, the ruling will be applied to the transaction.

Tariff classification rulings. Each ruling letter setting forth the proper classification of an article under the provisions of the Harmonized Tariff Schedule of the United States will be applied only with respect to transactions involving articles identical to the sample submitted with the ruling request or to articles whose description is identical to the description set forth in the ruling letter.

Valuation rulings. Each ruling letter setting forth the proper valuation of an article under the provisions of section 402 of the Tariff Act of 1930, as amended (19 U.S.C. 1401a), will be applied only with respect to transactions involving the same merchandise and like facts.

Carrier rulings. Each ruling letter setting forth the applicability of the navigation laws to a vessel will be applied only with respect to transactions involving operations identical to those set forth in the ruling letter. Each ruling letter setting forth a determination as to whether or not the primary object of a contemplated voyage is coastwise transportation in violation of 46 U.S.C. 289 will be binding on the United States Customs Service with respect to any transaction identical to the facts and circumstances described in the ruling request and undertaken in reliance on the ruling letter.
