USMCA Benefits for Canada-USA Trade

Tariff Reduction

Products meeting USMCA origin requirements qualify for reduced or eliminated tariffs, saving businesses significant costs on qualifying goods.

Certificate Requirements

To claim USMCA benefits, you must provide a Certificate of Origin signed by the importer, exporter, or producer certifying the goods meet origin criteria.

Regional Content Rules

Goods must typically contain a minimum percentage of North American content (usually 50-75%) to qualify for preferential treatment.
