19 C.F.R. § 191.32

(a) General. Section 313(j)(2) of the Act, as amended (19 U.S.C. 1313(j)(2)), provides for drawback on merchandise which is commercially interchangeable with imported merchandise if the commercially interchangeable merchandise is exported, or destroyed under Customs supervision, before the close of the 3-year period beginning on the date of importation of the imported merchandise, and before such exportation or destruction, the commercially interchangeable merchandise is not used in the United States (see paragraph (e) of this section) and is in the possession of the party claiming drawback.

(b) Requirements. (1) The claimant must have possessed the substituted merchandise that was exported or destroyed, as provided in paragraph (d)(1) of this section;

(2) The substituted merchandise must be commercially interchangeable with the imported merchandise that is designated for drawback;

(3) The substituted merchandise exported or destroyed must not have been used in the United States before its exportation or destruction (see paragraph (e) of this section); and

(4) For purposes of drawback of internal revenue tax imposed under Chapters 32, 38 (with the exception of Subchapter A of Chapter 38), 51, and 52 of the Internal Revenue Code of 1986, as amended (IRC), drawback granted on the export or destruction of substituted merchandise will be limited to the amount of taxes paid (and not returned by refund, credit, or drawback) on the substituted merchandise.

(c) Determination of commercial interchangeability. In determining commercial interchangeability, Customs shall evaluate the critical properties of the substituted merchandise and in that evaluation factors to be considered include, but are not limited to, Governmental and recognized industrial standards, part numbers, tariff classification and value. A party may seek a nonbinding predetermination of commercial interchangeability directly from the appropriate drawback office. A determination of commercial interchangeability can be obtained in one of two ways:

(1) A formal ruling from the Entry Process and Duty Refunds Branch, Regulations and Rulings, Office of International Trade; or

(2) A submission of all the required documentation necessary to make a commercial interchangeability determination with each individual drawback claim filed.

(d) Time limitations. For substitution unused merchandise drawback:

(1) The claimant must have had possession of the exported or destroyed merchandise at some time during the 3-year period following the date of importation of the imported designated merchandise; and

(2) The merchandise to be exported or destroyed to qualify for drawback must be exported, or destroyed under Customs supervision, before the close of the 3-year period beginning on the date of importation of the imported designated merchandise.

(e) Operations performed on substituted merchandise. In cases in which an operation or operations is or are performed on the substituted merchandise, the performing of any operation or combination of operations, not amounting to manufacture or production under the provisions of the manufacturing drawback law, on the commercially interchangeable substituted merchandise is not a use of that merchandise for purposes of this section.

(f) Designation by successor; 19 U.S.C. 1313(s)—(1) General rule.

(i) All or substantially all of the rights, privileges, immunities, powers, duties, and liabilities of the predecessor; or

(ii) The assets and other business interests of a division, plant, or other business unit of such predecessor, provided that the value of the transferred assets and interests (realty, personality, and intangibles, exclusive of the drawback rights) exceeds the value of such drawback rights, whether vested or contingent.

(3) Certifications and required evidence—(i) Records of predecessor. The predecessor or successor must certify in an attachment to the drawback claim that the successor is in possession of the predecessor's records which are necessary to establish the right to drawback under the law and regulations with respect to the imported and/or commercially interchangeable merchandise.
