Duty drawback, the refund of 99 percent of duties paid on imported merchandise that is later exported or destroyed, runs today under the rules Congress set in the Trade Facilitation and Trade Enforcement Act, fully implemented in ACE with the old paper processes retired. The framework importers now live with: a five year window between import and the completed drawback claim, substitution judged on the eight digit HTSUS classification rather than the old commercial interchangeability tests for most manufacturing and unused merchandise claims, core and additional recordkeeping requirements spelled out in 19 CFR Part 190, and accelerated payment as a privilege earned with a bond and a compliance record, not a default. For claimants the practical shift is evidentiary. The claim succeeds or fails on whether the records connect the imported article to the exported article at the level the regulation demands, and that connection has to be built in the ordinary course of business, not reconstructed the quarter the claim is filed.
Substitution got simpler to state and harder to fake
The eight digit standard cut both ways. Claimants no longer litigate whether two articles are commercially interchangeable in the old fact heavy sense for the core substitution categories; classification at the eight digit level does the work, subject to the rule that if the eight digit line carries a specific duty rate description the comparison drops to that level of detail. That simplification moved the fight to classification accuracy itself. A drawback program built on sloppy inbound classification inherits the sloppiness at refund time, with interest, because the exported article's classification and the imported article's classification now have to meet on the page.
Perpetual and blanket arrangements also matured under the new regime. Importers with steady flows run drawback as a standing program with waivers of prior notice where approved and rulings covering their methodology, rather than as a series of individual claims assembled by hand. The standing program is where the money is for repeat exporters: the refund becomes a predictable line in the export margin instead of an occasional recovery project that finance treats as found money and operations treats as an interruption.

The record is the claim
Part 190 recordkeeping is not a suggestion to keep good files. The claimant must be able to prove import, with the entry summary and duty payment; possession and transfer through the chain where intermediaries handled the goods; and export, with the export documentation that ties the shipment to the drawback designation. Inventory methodology does the heavy lifting for fungible goods: FIFO, LIFO, or another approved accounting method, applied consistently, is what connects a specific export to the pool of imports when the physical article cannot be traced. Claimants get in trouble by treating the methodology as a claim time choice. It is an inventory system decision, made when the goods move, and the claim merely reports it.
Keep the clock in the same system. Five years sounds generous until a program discovers a rich vein of unclaimed exports in year four and a half, against imports whose records sit in a retired system. A drawback calendar that ages potential claims the way the open entry report ages entries converts that discovery from an emergency into a filing queue.
Frequently asked questions
What is duty drawback?
Drawback is the refund of up to 99 percent of customs duties paid on imported merchandise that is subsequently exported or destroyed without entering US commerce in its imported form, claimed under 19 CFR Part 190.
How long does an importer have to file a drawback claim?
Under the modernized rules the claim must be completed within five years of the import date of the merchandise the claim is based on. Tracking that window against aging imports is a core part of running a drawback program.
What does substitution mean in drawback?
Substitution lets a claimant export a commercially equivalent article, judged principally on eight digit HTSUS classification under the current rules, and claim drawback against duties paid on the imported article, rather than having to export the identical physical item.
What records support a drawback claim?
Entry summaries and proof of duty payment for the import, inventory and transfer records applying a consistent accounting method, and export documentation tying the exported merchandise to the claim. The connection must exist in ordinary business records, not be reconstructed at filing.
