Drawback is the refund of duty paid on imported merchandise that is later exported or destroyed, and the common thread is proof of two events: duty was paid on import, and the same goods, or goods made from them, left the country or were destroyed under supervision. A drawback claim lives or dies on linkage. You need the entry summary showing duty paid, inventory records showing the goods were received and tracked, and export documents showing they left. For manufacturing claims, bills of material and production records connect imported inputs to exported finished goods. CBP allows designated methods such as first in first out accounting, but the method must be consistent and documented before the audit, not invented during it.
The scale of the unclaimed money is the reason the paperwork matters. Industry estimates suggest only 5 to 10 percent of eligible drawback is actually claimed, leaving several billion dollars in unclaimed refunds annually, because companies do not know the program exists, believe their products do not qualify, or find the record-keeping burden too daunting without a specialist. The claims that are filed fail on paperwork more often than on eligibility, and the paperwork failures are the same three mistakes every time. The drawback claim file is the documents CBP asks for, and the file is the claim: without it, there is nothing to pay.
Mismatch is the top problem: quantities on export documents that do not reconcile to import quantities, part numbers that changed names between systems, or export proof that is a booking confirmation instead of a filed export record. Each mismatch turns a payable claim into correspondence, and the correspondence is where the five-year clock runs out. The fix is a single part-number map across the import, inventory, and export systems, maintained before the claim is filed, not reconstructed after CBP asks. A part number that changed names between systems is a mismatch until someone maps it, and the mapping has to be documented, not remembered.
Missing export proof is the other classic gap. A commercial invoice to a foreign buyer is not proof of export by itself. Parcel exports often lack EEI filings, and carrier data can fill the gap, but it has to be collected. The proof CBP wants is the export record: the EEI filing, the carrier's proof of export, or the bill of lading showing the goods left. A booking confirmation is not an export record, and a commercial invoice is not proof the goods left the country. The export proof has to be collected at the time of export, because reconstructing it months later is how claims get denied.
The wrong claim type is the third mistake. Using the wrong category, like filing under unused merchandise when the goods were actually manufactured, can result in a rejected claim. Unused merchandise drawback covers goods exported in the same condition they were imported, under 19 USC 1313(j), and manufacturing drawback covers goods built from imported inputs and then exported, under 19 USC 1313(a) and (b), and manufacturing drawback needs an approved ruling describing the production process. Substitution drawback claims duty back on goods you never exported, and the substitution has to be commercially interchangeable goods under the same 8-digit tariff code, not just similar goods. The five-year clock and the three-year record rule are the deadlines that turn a paperwork mistake into a lost refund.
The file is the entry summary, the inventory records, the export documents, and the part-number map, kept together from the day the goods arrive, not assembled when the claim is filed. Claims filed after the fact with reconstructed records are frequently denied, and inadequate records are the primary cause of claim denials and penalties. The goods must be exported or destroyed within five years of the import date, and the claim must be filed within that same five-year period. Records must be retained for three years after the drawback claim is paid. Most claimants need drawback privileges approved before filing accelerated claims, and manufacturing drawback needs an approved ruling before the claim, not after.
The other check is which duties qualify. Section 232 duties on steel, aluminum, and their derivatives are barred from drawback by the 2025 proclamations, and IEEPA duties are refunded through a separate CBP process, not drawback. Mixing either into a claim causes rejections. Antidumping and countervailing duties are generally not eligible either. The claim that files only the qualifying duties, with the linkage documented, is the claim that gets paid. The claim that files everything and hopes CBP sorts it out is the claim that gets denied, and the denial arrives after the five-year clock has already run out on the oldest entries.
Mismatch: quantities on export documents that do not reconcile to import quantities, part numbers that changed names between systems, or export proof that is a booking confirmation instead of a filed export record. Each mismatch turns a payable claim into correspondence.
No. A commercial invoice to a foreign buyer is not proof of export by itself. CBP wants the export record: the EEI filing, the carrier's proof of export, or the bill of lading showing the goods left.
The claim can be rejected. Unused merchandise covers goods exported in the same condition they were imported. Manufacturing drawback covers goods built from imported inputs and exported, and it needs an approved ruling describing the production process.
Goods must be exported or destroyed within five years of the import date, and the claim must be filed within that same five-year period. Records must be retained for three years after the claim is paid.
