Frequently Asked Questions

Did USMCA change the duty drawback rules from NAFTA?

Not much. USMCA carried NAFTA’s drawback restrictions forward largely intact. The lesser-of limitation still applies to most claims on goods exported to Canada or Mexico, same-condition exports remain fully eligible, and substitution claims still cannot use exports to either country. For drawback purposes, the transition changed less than the name did.

What is the lesser-of rule?

It caps drawback on goods exported to Canada or Mexico at the lower of two figures: the duties paid when the goods entered the United States, or the duties paid when they entered Canada or Mexico. Because qualifying goods enter those markets duty free under USMCA, the lower figure is often zero.

Do any exports to Canada or Mexico escape the limit?

Yes. Goods exported in the same condition they arrived in, meaning unused merchandise claims with direct identification, qualify for full drawback with no lesser-of cap. The limit mostly bites on manufactured goods, which is why sorting a program’s exports by destination and claim type matters so much.
