Substitution Drawback

Last updated October 1, 2026

Definition

Substitution drawback lets you claim a refund of duties paid on imports when the goods you export or destroy are different but interchangeable goods classified under the same 8-digit HTS subheading. It applies to unused merchandise (19 U.S.C. 1313(j)(2)) and to manufacturing (1313(b)), works within five years of import, and refunds up to 99% of the lesser of the duty paid on the import or the duty that would apply to the substituted goods.

How similar do substituted goods have to be?

Since TFTEA, the test is the tariff classification. The substituted goods must be classifiable under the same 8-digit HTS subheading as the duty-paid imports. For unused merchandise, the substitute can be imported or domestic. There is one important exception: if the article description of that 8-digit subheading begins with "other", the goods must share the same 10-digit statistical reporting number instead, and that description cannot begin with "other" either (19 U.S.C. 1313(j)(5)). Before TFTEA, the standards were "commercially interchangeable" for unused merchandise and "same kind and quality" for manufacturing, which took far more judgment to apply.

How is the refund calculated for a substitution claim?

Substitution claims use the lesser-of rule: the refund is 99% of the lower of (a) the duty paid on the designated import or (b) the duty that would apply to the substituted goods if they were imported. For example, if you paid $10,000 in duty on the import and the exported goods would have owed $6,000, the refund is 99% of $6,000, or $5,940. Accurate HTS classification of both the imports and the exports is what makes the calculation defensible.

Why does matching matter more for substitution claims?

With substitution, many imports can be paired with many exports in the same subheading, and each import can be claimed only once. Because of the lesser-of rule and differences in duty rates between entries, which import you designate against which export changes the refund. Pairing them first-in-first-out is simple but rarely recovers the most. See drawback matching.

What records do you need for substitution drawback?

Keep the import entries that show the classification and the duties, taxes and fees paid, the export or destruction records with the classification of the exported goods, and the records that show the substituted goods were not used in the United States (for unused merchandise) or were used in manufacturing (for manufacturing claims). Claims are filed in ACE within five years of the import date.

Frequently asked questions

How does substitution drawback work?

You designate duty-paid imports and export or destroy other goods classifiable under the same 8-digit HTS subheading within five years of import. CBP refunds up to 99% of the lesser of the duty paid on the import or the duty that would apply to the substituted goods.

Can I substitute domestic goods for imported goods?

For unused merchandise drawback, yes: 19 U.S.C. 1313(j)(2) allows other merchandise, imported or domestic, classifiable under the same 8-digit HTS subheading, as long as it was not used in the United States before export or destruction.

What if the HTS description starts with "other"?

Then the 8-digit match is not enough. The goods must share the same 10-digit HTS statistical reporting number, and that description cannot begin with "other" either.
