Summary

The proclamation imposes an additional 50% ad valorem (value-based) duty on certain Canadian products identified in Annex II. The document states the measure is intended to offset what it describes as Canada's discriminatory treatment of U.S. motor vehicle exports under Canada's tariff system.

What it does#

  • Imposes an additional 50% duty on specified Canadian products.
  • States that the new duty is in addition to other applicable duties, taxes, and fees, except where the proclamation provides exclusions.
  • Modifies the Harmonized Tariff Schedule of the United States (HTSUS) to implement the new duties.
  • Directs U.S. Customs and Border Protection (CBP) to issue any rules, guidance, and technical tariff changes needed to administer the proclamation.

Who it affects#

  • Importers of the Canadian products listed in Annex II.
  • Businesses importing covered Canadian goods into the United States.
  • U.S. Customs and Border Protection and other federal agencies responsible for implementing the tariff changes.

Why the proclamation says it was issued#

The proclamation states that Canada applies tariffs and tariff-rate quotas to certain U.S. motor vehicles while treating imports from other countries more favorably. It cites section 338 of the Tariff Act of 1930 as authority for imposing additional duties to offset what the proclamation characterizes as discrimination against U.S. commerce.

When it takes effect#

The additional duties apply to covered goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. Eastern Time on August 19, 2026.
