USMCA Duty-Free
Freight Checker

⚠ Tariff Shift Rules Apply

When non-North American materials are used in production, USMCA duty-free eligibility depends on whether those inputs undergo a sufficient change in tariff classification (HTS heading or subheading) during manufacturing within a USMCA territory.

Under the Tariff Shift Rule (TSR), an imported input classified under one HTS chapter must emerge from the production process classified under a different chapter, heading, or subheading — the specific rule varies by product category.

This significantly increases documentation burden. A Complex Origin Audit is recommended before tendering this freight.
