Duty Drawback for Manufacturers Recover Up to 99% of Import Duties

Manufacturing drawback — formally known as manufacturing or production drawback under 19 CFR Part 191 — allows U.S. manufacturers to recover up to 99% of the import duties paid on raw materials or components that are used in the production of finished goods that are subsequently exported. The manufacturer must document the nexus between the imported inputs and the exported end product. CBP then refunds the eligible duties, taxes, and fees associated with those imported materials.

CBP typically requires import entry summaries, commercial invoices, bills of lading, production records showing consumption of imported materials, and export documentation for the finished goods. The specific records needed depend on the accounting method used — FIFO, LIFO, or averaging. Maintaining a clear audit trail linking each imported input to a specific export is critical. Missing or inconsistent documentation is one of the most common reasons manufacturing drawback claims are delayed or denied.

Manufacturing drawback applies when imported materials are used in a production process and the resulting finished goods are exported. Unused merchandise drawback applies when imported goods are re-exported in substantially the same condition in which they were imported — no manufacturing involved. Manufacturers typically qualify primarily for manufacturing drawback, but may also qualify for unused merchandise drawback on components that were never consumed in production.

With traditional providers using manual workflows and legacy software, manufacturing drawback claims typically take 9–12 months from start to refund. Zollback's automated platform compresses that timeline to 10–15 working days by eliminating manual data entry and running algorithmic optimization instead of manual Excel matching. The 5-year statute of limitations means manufacturers can also file retroactive claims on duties paid in prior years.

Yes, though many smaller manufacturers have historically been turned away by legacy drawback providers whose business models require large enterprise claim volumes to be profitable. Zollback's automation lowers the cost-to-serve enough to profitably handle manufacturers across a wide range of revenue sizes, making duty drawback accessible to companies that previously had no viable option for recovering their import duties.

Substitution manufacturing drawback allows manufacturers to claim drawback using domestically sourced materials of the same kind and quality as the imported materials — even if the specific imported goods were not themselves used in the exported product. This can significantly expand a manufacturer's eligible refund pool. Eligibility depends on matching HTS classifications and other regulatory criteria under 19 CFR Part 190, the modernized drawback regulations that took effect in 2019.
