USMCA Origin Can Preserve Drawback on Section 338 Tariffs
USMCA origin can preserve Section 338 drawback on Canadian inputs used in U.S. goods exported to Canada or Mexico, even when it provides no entry exemption.

The October 23 proclamation changes the Canadian products subject to Section 338 tariffs on October 30. U.S. manufacturers using covered Canadian inputs need to revise their entry calculations, but they also have a recovery question that does not depend on a new trade agreement. USMCA origin can preserve a drawback claim after those inputs are manufactured into goods exported to Canada or Mexico, even though it does not exempt the inputs from Section 338 at the U.S. border.
The distinction follows from two existing rules. CBP's Section 338 guidance makes the additional duties eligible for drawback. 19 CFR 182.45(a)(2) exempts qualifying Canadian or Mexican originating inputs from the usual limit tied to duties paid in the export destination. For a U.S. manufacturer's customs manager, that makes the imported material's origin evidence a priority in the direct-identification manufacturing drawback file.
This recovery route predates the October amendment. Qualifying manufacture, export and a complete claim are still required, and the importer must finance the original duty payment.
October 30 changes coverage, not the origin test
The October 23 action, collected in the Section 338 official-action record, removes some Canadian products from the additional 50% tariff and adds others. Its changes apply to consumption entries and warehouse withdrawals for consumption from one minute after midnight, eastern time, on October 30. The accompanying White House fact sheet expressly says covered goods face Section 338 regardless of USMCA origin.
Traverse's analysis of the packaging and cold-storage changes explains why related purchases can move in opposite tariff directions. A manufacturer should first establish which inputs actually incur the duty. An exemption on a future entry creates no Section 338 payment to recover from that entry.
For duties already paid, the amendment supplies no automatic retrospective refund. Drawback rests on the imported merchandise's subsequent use and export. Removing a product from the tariff list and recovering duty on an earlier qualifying import are different transactions.
The imported material's origin determines the exception
Under the general USMCA drawback calculation in 19 CFR 182.44, recovery is limited by the lower of the U.S. import duty and the duty paid when the exported good enters Canada or Mexico. A zero-duty entry in the destination can therefore eliminate recovery under that comparison.
Section 182.45(a)(2) removes that limitation when the dutiable imported material itself originates under USMCA and is used to produce another good subsequently exported to Canada or Mexico. The relevant origin rules are General Note 11 of the HTSUS and Appendix A to Part 182. Canadian shipment or a Canadian supplier's address does not establish that qualification. Nor does the finished product's USMCA status prove the origin of each imported input.
The regulation's heading, goods eligible for full drawback, does not mean a 100% refund here. Direct-identification manufacturing drawback under 19 CFR 190.21 remains capped at 99% of eligible duties, taxes and fees. The originating-input exception removes the USMCA comparison limit, not that ceiling.
A zero-duty export can produce two different results
Consider a hypothetical $100,000 of Canadian inputs subject to a 50% Section 338 duty. The importer pays $50,000 under that measure. Assume all of those inputs are properly identified to eligible U.S.-manufactured goods exported to Mexico without prior U.S. use. The finished goods enter Mexico with zero customs duty, and every other requirement for the claim is satisfied.
Treatment of the imported inputs
Maximum recovery of the $50,000 Section 338 component
Inputs satisfy the originating-goods exception in 19 CFR 182.45(a)(2)
$49,500, applying the 99% manufacturing drawback ceiling
Inputs do not satisfy that exception, and no other exception applies
$0, because the destination duty in the lesser-of comparison is zero
Illustration as of October 28, 2026, applying the USMCA comparison and exceptions and the manufacturing drawback ceiling. These hypothetical figures exclude other duties, fees, multiple-output allocations and financing or administrative costs. They make no finding about a particular product's origin.
The consequence is substantial even without a rate change. Two imports carrying the same Section 338 payment can have different recoverable costs after U.S. manufacturing. A sourcing comparison that records only the duty paid at entry misses that distinction. Conversely, treating the possible $49,500 recovery as an immediate cash saving would understate the funding requirement.
Build the claim around the actual production record
The customs manager should connect the imported material's origin support to its entry line, duty payment, manufacturing record and export. 19 CFR 190.51 requires detailed tracing and claim data, including the relevant manufacturing ruling, import information and evidence of exportation. A supplier certificate detached from the material used in production cannot establish that complete chain.
Direct identification keeps this inquiry focused on the imported merchandise used in the exported articles. Section 190.21 requires the manufactured articles to leave the United States without prior U.S. use. Domestic sales do not satisfy that export condition. Where production yields several products, the regulation requires allocation by their relative values. The simplified example assumes none of those allocation issues reduces the eligible amount.
Keep other duty components separate. CBP's Section 338 drawback eligibility does not establish the treatment of a Section 232 payment or another charge on the same entry. Each needs its own authority and eligibility assessment.
Non-originating inputs also require care before assigning a zero recovery. Section 182.45 contains other exceptions, including qualifying same-condition direct-identification exports. Those are separate routes. They should not be confused with the manufacturing example above or dismissed simply because the input fails USMCA origin.
Both manufacture and export must occur within five years of importation under 19 CFR 190.27(a). The ordinary deadline for a complete claim is also five years from importation under 19 CFR 190.51(e). A prospective trade agreement does not complete that file or preserve missing production records. For newly covered inputs, begin the origin and tracing review when the import is planned. For earlier duty payments, test the existing records now. Revisit the claim when an operative tariff change, the export destination or new evidence about the input's origin changes its eligibility or recoverable amount.
