Short answer: A duty drawback claim requires proving three things with documents: that you paid duty on the imported goods, that the same or commercially interchangeable goods were exported, and that the import and export are linked within the legal timeframes. The paperwork trail runs from the import entry summaries and duty payment records, through inventory records showing what happened to the goods, to the export documentation: bills of lading, export invoices, and proof of export. Most claims fail not on eligibility but on record-keeping: the goods qualify, but the brand cannot produce the chain of documents connecting the import to the export. Building that chain starts before the first shipment, not when you file.
The three things you must prove
Every drawback claim, regardless of type, has to establish the same triangle. First, the import: entry summaries showing the goods entered, the classification used, and the duties paid. Second, the export: documentation that goods left the country, with enough detail to identify them. Third, the link: records showing the exported goods are the imported goods, or qualifying substitutes, and that everything happened within the statutory time limits, generally five years from import to export in the US.
The link is where claims die. A brand that imports components, manufactures, and exports finished products needs production records tying specific import lots to specific export shipments. A brand claiming unused-merchandise drawback needs inventory records showing the goods were not used before export. Customs does not take your word for any of this; the documents either form an unbroken chain or the claim gets denied.
The import-side documents
Start with the CBP entry summaries, the 7501 forms, for every import you intend to claim against. These show the entered value, classification, and duty paid, and they are the foundation of the claim amount. Keep the commercial invoices, packing lists, and proof of duty payment alongside them. If you used a broker, make sure you actually receive and retain these documents rather than assuming the broker's files are yours.
For manufacturing drawback, add the production records: bills of material, manufacturing logs, and inventory movements showing imported inputs becoming exported outputs. For substitution drawback, where commercially interchangeable goods are exported instead of the exact imported lot, you need the records proving interchangeability, which is a factual claim customs will test. Organize import documents by entry number from day one; reconstructing them years later during a claim is where most of the pain lives.
The export-side documents
Proof of export is more demanding than many brands expect. The bill of lading or air waybill shows the goods left, but drawback wants more: export invoices describing the goods, packing lists, and evidence of delivery to the foreign destination. For exports to related parties, customs scrutinizes the documentation more closely, so arm's-length paperwork standards apply even to intercompany shipments.
Electronic export information filed through AES is part of the record, and the details in it should match your claim documents. Inconsistencies between the AES filing and the drawback claim, in quantities, values, or descriptions, are a common reason for delays and denials. Treat every export as a potential drawback export from a documentation standpoint, because you cannot go back and create this paperwork after the goods have shipped.
Building the system before you need it
The brands that collect drawback successfully treat it as a process, not a project. That means a document retention policy that keeps import and export records for the full statutory period, inventory systems that track lots from receipt through export, and a quarterly review that matches exports against import entries to identify claimable shipments before the paperwork goes cold.
Most brands use a drawback specialist or broker for filing, and that is usually the right call: the regulations are detailed and the claim preparation is technical. But the specialist can only work with the records you kept. The division of labor is clear. You own the document chain through your daily operations; the specialist turns it into a filed claim. Start keeping the records now, even if you do not plan to file for a year, because the claims you file then will depend on the documents you keep today.
How far back can I claim?
In the US, the export generally must occur within five years of the import, and claims are subject to filing deadlines after export. Do not assume old shipments are claimable; check the timeframes before investing in reconstructing the paperwork. The clock runs from specific events, so get the dates right.
Can I claim drawback on goods I already sold domestically?
No. Drawback requires export or destruction under customs supervision. Goods sold domestically do not qualify, even if identical goods were exported. The export has to be real and documented, which is why the proof-of-export requirements are strict.
Is drawback worth it for a small brand?
It depends on the duty paid and the export volume. Filing has costs, whether you do it in-house or through a specialist, and small claims may not justify them. But the analysis should use your actual duty spend, which surprises many brands once they add it up. Run the numbers before dismissing it.
