CUSMA/USMCA rules of origin: when 'Made in North America' actually saves you duty

The Canada–United States–Mexico Agreement (CUSMA, or USMCA in the US) eliminates duties on most goods traded within North America — but only for goods that qualify as originating, and only when the claim is properly certified. Neither happens by default.

Origin is determined by product-specific rules: some goods qualify by being wholly produced in the region, others through a tariff-shift test (non-originating inputs change classification during manufacturing), and others by regional value content thresholds. A product assembled in Ontario from imported components may or may not qualify — the rule for its specific HS code decides.

Certification is self-declared under CUSMA: no government-stamped certificate exists. The certifier provides a set of minimum data elements and takes legal responsibility for the claim. That flexibility cuts paperwork but raises audit exposure — customs authorities in all three countries verify claims, and an unsupported claim means repaid duties plus penalties.

For manufacturers, the practical move is a solid origin analysis per product family, refreshed when sourcing changes. For importers, ask your supplier for the certification data before the goods ship, not after entry. We help clients build both — the analysis and the document trail that survives a verification.

One more note: even where most-favoured-nation duty is already zero, CUSMA claims can still matter for other measures. When trade policy shifts quickly — as it has across North America in recent years — documented origin is an asset.
