19 C.F.R. § 190.51
(2) Drawback entry. The drawback entry is to be filed through a CBP-authorized electronic system and must include the following:
(xi) Indicate whether the eligible merchandise was exported or destroyed and provide the applicable 10-digit HTSUS or Department of Commerce Schedule B classification, quantity, and unit of measure (the unit of measure specified must be the same as that which was required under the HTSUS for the designated imported merchandise in paragraph (viii) for substitution unused merchandise drawback claims) and, for claims under 19 U.S.C. 1313(c), specify the basis as one of the following:
(b) Drawback due—(1) Claimant required to calculate drawback. Drawback claimants are required to correctly calculate the amount of drawback due. The amount of drawback requested on the drawback entry is generally to be 99 percent of the duties, taxes, and fees eligible for drawback. (For example, if $1,000 in import duties are eligible for drawback less 1 percent ($10), the amount claimed on the drawback entry should be for $990.) Claims exceeding 99 percent (or 100% when 100% of the duty is available for drawback) will not be paid until the calculations have been corrected by the claimant. Claims for less than 99 percent (or 100% when 100% of the duty is available for drawback) will be paid as filed, unless the claimant amends the claim in accordance with § 190.52(c). The amount of duties, taxes, and fees eligible for drawback is determined by whether a claim is based upon direct identification or substitution, as provided for below:
(2) Merchandise processing fee apportionment calculation. Where a drawback claimant requests a refund of a merchandise processing fee paid pursuant to 19 U.S.C. 58c(a)(9)(A), the claimant is required to correctly apportion the fee to that imported merchandise for which drawback is claimed when calculating the amount of drawback requested on the drawback entry. This is determined as follows:
(v) Limitation on amount of merchandise processing fee eligible for drawback for substitution claims. The amount of a merchandise processing fee eligible for drawback per unit of merchandise for drawback claims based upon substitution is subject to the limitations set forth in §§ 190.22(a)(1)(ii) (manufacturing claims) and 190.32(b) (unused merchandise claims), as applicable.
Example 1: Line item 1—5,000 articles valued at $10 each total $50,000 Line item 2—6,000 articles valued at $15 each total $90,000 Line item 3—10,000 articles valued at $20 each total $200,000 Total units = 21,000 Total value = $340,000 Merchandise processing fee = $485 (for purposes of this example, the fee cap of $485 is assumed; see 19 CFR 24.23 for the current amount consistent with 19 U.S.C. 58c(a)(9)(B)(i)). Line item relative value ratios. The relative value ratio for line item 1 is calculated by dividing the value of that line item by the total value ($50,000 ÷ 340,000 = .1471). The relative value ratio for line item 2 is .2647. The relative value ratio for line item 3 is .5882.Merchandise processing fee apportioned to each line item. The amount of fee attributable to each line item is calculated by multiplying $485 by the applicable relative value ratio. The amount of the $485 fee attributable to line item 1 is $71.3435 (.1471 × $485 = $71.3435). The amount of the fee attributable to line item 2 is $128.3795 (.2647 × $485 = $128.3795). The amount of the fee attributable to line item 3 is $285.2770 (.5882 × $485 = $285.2770).Amount of merchandise processing fee eligible for drawback per line item. The amount of merchandise processing fee eligible for drawback for line item 1 is $70.6301 (.99 × $71.3435). The amount of fee eligible for drawback for line item 2 is $127.0957 (.99 × $128.3795). The amount of fee eligible for drawback for line item 3 is $282.4242 (.99 × $285.2770).Amount of merchandise processing fee eligible for drawback per unit of merchandise. The amount of merchandise processing fee eligible for drawback per unit of merchandise is calculated by dividing the amount of fee eligible for drawback for the line item by the number of units in the line item. For line item 1, the amount of merchandise processing fee eligible for drawback per unit is $.0141 ($70.6301 ÷ 5,000 = $.0141). If 1,000 widgets form the basis of a claim for drawback under 19 U.S.C. 1313(j), the total amount of drawback attributable to the merchandise processing fee is $14.10 (1,000 × .0141 = $14.10). For line item 2, the amount of fee eligible for drawback per unit is $.0212 ($127.0957 ÷ 6,000 = $.0212). For line item 3, the amount of fee eligible for drawback per unit is $.0282 ($282.4242 ÷ 10,000 = $.0282).
Example 2.This example illustrates the treatment of dutiable merchandise that is exempt from the merchandise processing fee and duty-free merchandise that is subject to the merchandise processing fee. Line item 1—700 meters of printed cloth valued at $10 per meter (total value $7,000) that is exempt from the merchandise processing fee under 19 U.S.C. 58c(b)(8)(B)(iii) Line item 2—15,000 articles valued at $100 each (total value $1,500,000) Line item 3—10,000 duty-free articles valued at $50 each (total value $500,000) The relative value ratios are calculated using line items 2 and 3 only, as there is no merchandise processing fee imposed by reason of importation on line item 1. Line item 2—1,500,000 ÷ 2,000,000 = .75 (line items 2 and 3 form the total value of the merchandise subject to the merchandise processing fee). Line item 3—500,000 ÷ 2,000,000 = .25. If the total merchandise processing fee paid was $485, the amount of the fee attributable to line item 2 is $363.75 (.75 × $485 = $363.75). The amount of the fee attributable to line item 3 is $121.25 (.25 × $485 = $121.25).The amount of merchandise processing fee eligible for drawback for line item 2 is $360.1125 (.99 × $363.75). The amount of fee eligible for line item 3 is $120.0375 (.99 × $121.25).The amount of drawback on the merchandise processing fee attributable to each unit of line item 2 is $.0240 ($360.1125 ÷ 15,000 = $.0240). The amount of drawback on the merchandise processing fee attributable to each unit of line item 3 is $.0120 ($120.0375 ÷ 10,000 = $.0120).If 1,000 units of line item 2 were exported, the drawback attributable to the merchandise processing fee is $24.00 ($.0240 × 1,000 = $24.00).
(ii) Examples. As illustrated in the examples in this paragraph, in the case of customs duties, the type of calculation required to determine the amount of duties available for refund (generally 99% of the duties paid on the imported merchandise) will vary depending on whether the duty involved is ad valorem, specific, or compound.
Example 1: Ad valorem duty rate.Apportionment of the duties paid (and available for refund) will be based on the application of the duty rates to the per unit values of the imported merchandise. The per unit values are based on the invoice values unless the method of refund calculation is per unit averaging, which would require equal apportionment of the duties paid over the quantity of imported merchandise covered by the line item upon which the imported merchandise was reported on the import entry summary. As a result, the amount of duties available for refund will vary depending on the method used to calculate refunds.
Example 2: Specific duty rate.No apportionment of the duties paid is required to determine the amount available for refund. A fixed duty rate is applicable to each unit of the imported merchandise based on quantity. This fixed rate will not vary based on the per unit values of the imported merchandise and, as a result, there is no impact on the amount of duties available for refunds (regardless of whether the refunds are calculated based on invoice values or per unit averaging).
Example 3: Compound duty rate.A compound duty rate is a combination of an ad valorem duty rate and a specific duty rate, with both rates applied to the same imported merchandise. As a result, a combination of the calculations discussed in paragraphs (a) and (b) of this section will apply when calculating the amount of duties paid that are available for refund.
(c) HTSUS classification or Schedule B commodity number(s)—(1) General. Drawback claimants are required to provide, on all drawback claims they submit, the 10-digit HTSUS classification or the Schedule B commodity number(s), for the following:
(ii) Substituted merchandise on manufacturing claims. For merchandise substituted on manufacturing drawback claims, and consistent with the applicable general manufacturing drawback ruling or the specific manufacturing drawback ruling, the applicable HTSUS classification numbers must be the same as either—
(iv) Destroyed merchandise or articles. For destroyed merchandise or articles, the HTSUS classification or Schedule B commodity number(s) must be reported, subject to the following:
(e) Time of filing—(1) General. A complete drawback claim is timely filed if it is successfully transmitted not later than 5 years after the date on which the merchandise designated as the basis for the drawback claim was imported and in compliance with all other applicable deadlines under this part.
(2) Major disaster. The 5-year period for filing a complete drawback claim provided for in paragraph (e)(1) of this section may be extended for a period not to exceed 18 months if:
