If a business imports components, pays duty on them, builds a product, and exports that product, the tax system in the United States does not intend the duty to stick. Drawback is the mechanism that refunds it, historically ninety nine percent of duties, taxes, and certain fees on the exported article. It is also chronically underclaimed, because the records have to be built before the export, not reconstructed after it.
The main claim families
Manufacturing drawback covers imported material used in producing an exported article, in two flavours: direct identification, where the exact imported material is tracked into the export, and substitution, where fungible domestic or other imported material of the same kind and quality is used instead, under the modernised rules. Unused merchandise drawback covers imported goods exported in the same condition, the pure re export case, again with a substitution variant.
Each family has its own basis for calculating the refund and its own documentary chain. Choosing the wrong family, or mixing their logic in one claim, is a common reason claims stall in review. Map the claim type to the actual flow of goods before filing anything: what came in, what was done to it, what went out, and what evidence connects those three facts.
Records are the programme
A drawback claim lives or dies on linkage: import entry to inventory, inventory to production or storage, storage to export. Lot numbers, bills of material, production records, and export documentation must form an unbroken chain, retained for the period the rules require after liquidation of the claim. Companies that bolt drawback onto a warehouse system that was never asked to track lots will spend more reconstructing the chain than the refund returns.
Start with one product line and one flow, build the record chain for it until a claim files cleanly, then extend. Drawback programmes fail by ambition more often than by law: five product lines launched at once, none with records good enough to survive the first verification.
Timing, waivers, and the five year clock
Claims run against deadlines tied to the import and export dates, with an overall window measured in years, and exporters who want to claim before the underlying import entry liquidates, or to waive prior notice requirements, need the relevant privileges in place through the drawback programme's application process. Accelerated payment is a privilege, earned and maintained, not a default.
Diarise the clock per import lot, not per calendar. The oldest imports in a growing programme age out quietly while the team works on the newest claims, and expired drawback is not recoverable by apology, however good the underlying records are. A simple ageing report, reviewed monthly, is the control that separates programmes that collect from programmes that intend to.
Whether it pays is arithmetic, not enthusiasm
Model it honestly: annual dutiable imports that feed exports, the applicable refund percentage, minus broker or consultant fees, system changes, and the staff time to maintain the record chain to audit standard. High duty inputs and steady export volume clear that bar easily. Low duty, occasional exports often do not, and a smaller truth serves the business better: file unused merchandise claims on the clean re export flow only, and leave the manufacturing programme until volume justifies it.
Decide from the model, revisit it when rates or export share move, and remember the direction of travel: every new tariff layer on imported inputs makes the drawback on the exported output worth more, which is why programmes shelved in a low duty era keep coming back.

Frequently asked questions
How much duty does drawback refund?
In general, ninety nine percent of the duties, taxes, and certain fees paid on the imported goods or material, when the related article is exported or destroyed under the programme's rules. The calculation basis depends on the claim type.
What is substitution drawback?
Where the exported article was made from, or is, material of the same kind and quality as the imported material rather than the identical imported lot. Substitution rules have specific standards and timing, and they are what make drawback workable for fungible goods.
What records does a drawback claim need?
An unbroken chain: the import entry, inventory and lot records, production records where manufacturing is involved, and the export documentation, retained for the required period after the claim liquidates. Claims fail on gaps in that chain more than on law.
How long do I have to claim drawback?
Claims are subject to deadlines measured from import and export dates, generally within a five year framework under the modernised rules. Track the clock per import lot with an ageing report, because expired claims cannot be recovered.
