# President Revises Tariffs on Canadian Goods

President Donald J. Trump signed a proclamation changing which Canadian products are subject to an additional 50% ad valorem duty under Proclamation 11048. The revised treatment applies to covered goods entered for consumption, or withdrawn from warehouse for consumption, on or after October 30, 2026, and the duty applies in addition to Section 232 duties. A separate fact sheet describes further tariff changes under Section 338 of the Tariff Act of 1930 but does not specify affected products, rates, or an implementation date. For contractors and suppliers sourcing Canadian vehicles or other Canadian inputs, the changes may affect customs costs, bids, and supply-chain decisions; the October 30 effective date is six days away as of October 24, 2026.

- Companies sourcing motor vehicles or related products from Canada should review the proclamation’s HTSUS classifications and Annex I product lists to determine whether their goods are covered.
- Update landed-cost estimates and bids for applicable goods, accounting for the additional duty on top of Section 232 duties.
- For other Canadian-sourced inputs potentially affected by the Section 338 action, assess the proclamation’s product scope, rates, and effective date before revising pricing or delivery assumptions.
