Excluding Certain Canadian Products from Importation into the United States in Response to Continued Discrimination Against the Commerce of the United States with Respect to Motor Vehicles

Summary: This proclamation, signed September 8, 2026, escalates U.S. trade action against Canada over its motor vehicle tariff scheme, moving from tariffs to an outright import ban on certain goods. Background: Proclamation 11048 (July 2026) imposed additional duties on Canadian products after finding Canada discriminated against U.S. motor vehicle commerce. Proclamation 11056 (August 2026) briefly suspended those duties for 3 days after Canada pledged to fix the discrimination. Canada allegedly reneged on that commitment on August 21, 2026, so the suspended duties took effect August 22, 2026. New action: Having determined Canada still hasn't removed the discriminatory tariff scheme, Trump now excludes certain Canadian products (listed in an Annex) from importation into the U.S. entirely, effective September 29, 2026. Goods already imported but not yet entered for consumption before that date remain subject to the existing 50% duty rather than the new ban. This changes only the treatment of specified products from tariffs to an import ban — other products remain subject to the original duties. Implementation: U.S. Customs and Border Protection, in consultation with Treasury, Commerce, and the U.S. Trade Representative, is tasked with issuing rules and making any necessary tariff schedule modifications. Includes standard severability language: if the import ban is struck down for any product, that product reverts to the 50% duty rather than escaping restriction entirely.
