The USMCA Drawback Trap: When Exports to Canada or Mexico Cannot Support a Duty Refund
U.S. law restricts duty drawback on goods exported to USMCA countries. Substitution unused merchandise drawback is flatly unavailable for exports to Canada or Mexico. Manufacturing and direct identification drawback are available but capped at the lesser of U.S. duties paid or duties owed in the USMCA country — which, for goods that qualify for preferential tariff treatment, may be close to zero. These restrictions create a powerful incentive to misrepresent export destinations, and a company that acts on that incentive is filing false claims for payment from the United States.
Drawback — the refund of customs duties on imported goods that are subsequently exported or destroyed — is one of the oldest features of U.S. trade law. Under 19 U.S.C. § 1313, importers may recover up to 99 percent of the duties paid when goods leave the country. But the statute does not treat all exports equally. When goods are exported to a USMCA country — Canada or Mexico — the drawback rules change significantly, and in ways that many companies either do not understand or choose to ignore. The resulting misrepresentations are false claims for payment under the False Claims Act.
How the USMCA Restrictions Work
Two separate restrictions apply to drawback on goods exported to USMCA countries.
First, substitution unused merchandise drawback under § 1313(j)(2) is entirely unavailable for exports to Canada or Mexico. The statute provides that the exportation of merchandise that is fungible with and substituted for imported merchandise to a USMCA country “shall not constitute an exportation” for purposes of the substitution drawback provision. In practical terms, this means a company that imports duty-paid goods and exports commercially interchangeable (but not identical) goods to Canada cannot claim any unused merchandise drawback on the substitution basis. Only direct identification drawback — where the actual imported goods are traced and exported — remains available under § 1313(j)(1) for USMCA-bound shipments.
Second, for drawback types that do remain available for USMCA exports — direct identification unused merchandise drawback, manufacturing drawback, and others — the refund is capped under the “lesser of two duties” rule in § 1313(n). Drawback on goods exported to a USMCA country cannot exceed the lesser of the total U.S. duties paid on importation or the total duties paid on the goods in the USMCA country. If the goods qualify for preferential USMCA tariff treatment and enter Canada or Mexico duty-free, the drawback recovery is capped at zero. If the USMCA country imposes a small duty, the recovery is capped at that small amount, regardless of how much the importer paid in U.S. duties.
The policy rationale for these restrictions is that USMCA is designed to create a low-tariff zone among its members. Unlimited drawback would allow importers to use the United States as a duty-free pass-through for goods destined for Canada or Mexico — importing from a high-tariff origin, recovering the U.S. duties through drawback, and exporting into the USMCA market where the goods face little or no duty. The restrictions prevent this arbitrage.
The Fraud Incentive
The financial logic is straightforward. A company that imports goods from China at a 25% Section 301 rate and exports to a non-USMCA country can recover nearly the full 25% through drawback. The same company exporting the same goods to Canada, where they enter duty-free under USMCA, recovers nothing. The difference can be hundreds of thousands or millions of dollars annually for a mid-size importer-exporter.
This creates two distinct fraud patterns. The first is filing substitution drawback claims on goods that were actually exported to Canada or Mexico. The drawback claim reports a non-USMCA destination, but the goods went to a USMCA country. The second is more sophisticated: routing goods through a non-USMCA intermediary — exporting on paper to a third country, with the goods ultimately transshipped to their real Canadian or Mexican destination. In both cases, the drawback claim depends on an exportation that either did not happen as described or does not qualify under the statute.
There is also a perverse structural incentive around destruction. A company that possesses imported merchandise it cannot sell domestically and intends to dispose of faces a choice: export it to a USMCA country (recovering little or nothing in drawback) or destroy it under CBP supervision (recovering up to 99% of the duties paid, because the destruction provision is not subject to the USMCA drawback cap in the same way). A company that understands this incentive and responds by misrepresenting the disposition of merchandise — claiming destruction when the goods were actually exported to a USMCA country, or misrepresenting the export destination to avoid the cap — has made a knowing false statement on its drawback claim.
Hypothetical Fact Patterns
Substitution drawback claimed on exports to Canada. A consumer electronics distributor imports smartphones from China, paying Section 301 duties. It also sources commercially interchangeable phones domestically. The distributor exports a shipment of the domestically sourced phones to a Canadian wholesaler and files a substitution unused merchandise drawback claim under § 1313(j)(2), designating the Chinese imports as the basis for the refund. But the statute is explicit: substitution drawback is not available for exports to USMCA countries. The export to Canada does not qualify. Filing the claim is a false claim for payment. An employee in trade compliance, export operations, or accounting who knows the destination was Canada has identified an actionable violation.
Transshipment to avoid the lesser-of-two-duties cap. A manufacturer exports industrial components to Mexico under a long-term supply agreement. It also imports duty-paid raw materials and claims manufacturing drawback on its exports. Because the components qualify for USMCA preferential treatment in Mexico and enter at a near-zero duty rate, the lesser-of-two-duties cap limits drawback recovery to almost nothing. To avoid this, the company begins routing shipments through a logistics hub in a Central American country, reporting that country as the export destination on its drawback claims. The goods continue to Mexico. The drawback claims misrepresent the export destination and claim a refund the statute does not allow. An employee in logistics, supply chain, or trade compliance who knows the ultimate destination is Mexico has identified the fraud.
Destruction claimed when goods were re-exported to a USMCA country. An importer holds surplus inventory of imported duty-paid industrial materials. Rather than exporting the surplus to its Canadian affiliate — which would yield no drawback due to the USMCA cap — the company reports that it destroyed the merchandise under CBP supervision and files a drawback claim for the full duty amount. In reality, the merchandise was shipped to the Canadian affiliate. The destruction certification is false. An employee in warehouse operations or inventory management who knows the goods were shipped rather than destroyed has the evidence to support a qui tam claim.
What Employees Should Watch For
The USMCA drawback restrictions are well-established in the statute and implementing regulations, and any reasonably informed trade compliance professional knows they exist. A company that files drawback claims inconsistent with these restrictions is not making a judgment call about an ambiguous legal question — it is misrepresenting facts on a government filing.
Red flags include: drawback claims filed using the substitution method on exports the employee knows went to Canada or Mexico; internal instructions to report non-USMCA destinations on drawback claims when the employee knows the goods are bound for a USMCA country; shipments routed through third countries when the ultimate customer is in Canada or Mexico; destruction certifications filed on merchandise the employee knows was shipped rather than destroyed; and any pattern of drawback claims that systematically avoid reporting USMCA destinations despite the company’s actual export profile.

The False Claims Act allows individuals with original knowledge of this kind of fraud to file suit on behalf of the United States and share in any recovery.
