Duty Drawback: Recovering Duty on Goods You Re-Export

Duty paid on imported goods is not always a sunk cost. If the goods are later exported, a large share of that duty can be recovered, and most small and mid-sized importers never claim it.
Drawback is a statutory refund administered by CBP, and the reason it goes unclaimed is not complexity of principle. It is that nobody owns the process.
What drawback is
Drawback is a refund of duties, taxes and fees paid on imported merchandise that is subsequently exported or destroyed under CBP supervision.
The statutory basis is 19 U.S.C. 1313. For most claims the refund is 99 percent of the duties, taxes and fees paid, with the remaining one percent retained by CBP.
The claim is time-limited: it must be filed within five years of the date of importation.
The two common types
Type | Core condition | Typical use |
Unused merchandise | Imported goods exported without being used in the U.S. | Returns, cancelled orders, unsold stock |
Manufacturing (substitution) | Imported goods or substitutes used to make exported articles | Components assembled into exported finished goods |
Substitution allows a claim even where the exported article does not contain the specific imported item, provided the imported and exported goods are commercially interchangeable and fall within the same statutory class.
That rule is what makes drawback useful in practice, because it decouples the physical flow from the accounting flow.
Why so little is claimed
Three reasons. The refund arrives months after the export, so the team that paid the duty is not the team that benefits from recovering it.
The documentation requires a link between the import entry and the export documentation, and that link is usually held by different systems or different people.
And the amounts per shipment often look too small to justify the work, until they are added up over a year.
What the file needs
For each claim: the import entry summary showing duty paid, the export documentation proving the goods left the United States, and the record connecting them.
For manufacturing claims, add the bill of materials and the production records. For substitution claims, the documentation that establishes commercial interchangeability.
The claim is filed with CBP, and like most customs processes it is judged on documentation rather than on narrative.
When it is worth doing
The threshold is not the size of an individual shipment, it is the total annual duty on goods that are exported. A company that imports components and exports finished goods, or that handles a meaningful volume of returns and resales abroad, usually has a claim worth pursuing.
The practical first step is not a filing. It is a reconciliation: take last year's entries, match them against exports, and see what the number actually is.
The mechanics of a claim
A claim involves a drawback entry, the export documentation, and the records that connect them. CBP Form 7551 is the claim itself; supporting documents establish the import, the export and the linkage.
The claim can be filed after export, so the sequencing is less rigid than it appears. What is rigid is the five-year window from the date of importation.
Many importers use a specialist drawback broker, because the documentation requirements are specific and the volumes are often small. The fee is usually a percentage of the recovery, which makes the decision easy to evaluate.
Why companies skip it
Three reasons, all rational in isolation. The recovery arrives long after the cost, so it does not appear in the budget of the person who paid the duty.
The documentation spans import and export records, which sit in different systems. And the first claim is genuinely time-consuming, because the mapping has to be built from scratch.
The counter-argument is arithmetic. If you know the annual duty on exported goods, the cost of a specialist claim is usually a fraction of the recovery. The first step is not a filing; it is that one number.
Drawback versus other relief
Drawback is one of several mechanisms, and it is not always the right one.
A bonded warehouse allows duty to be deferred until goods leave the warehouse, which helps cash flow but does not eliminate the duty. A foreign trade zone allows duty to be deferred or avoided where goods are re-exported, and can also allow inverted tariff treatment.
Drawback is the simplest to operate for companies that already export and do not want a zone. The zone is more powerful and considerably more expensive to establish.
The decision depends on volume and on how predictable the export flow is. A company exporting occasionally should look at drawback. One that exports most of what it imports should look at a zone.
Drawback is one of the few places in customs where the money flows back. It stays unclaimed because it requires one person to own a process that spans two departments.
