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 Dairy

Summary: This proclamation, signed September 8, 2026, escalates U.S. trade action against Canada's dairy tariff-rate quota practices, moving from tariffs to an import ban — mirroring the same-day action on motor vehicles. Background: Proclamation 11047 (July 2026) imposed 50% ad valorem duties on Canadian dairy products after finding Canada discriminated against U.S. cheese exports through its tariff-rate quota allocation measures. Proclamation 11056 (August 2026) briefly suspended these duties for 3 days after Canada pledged to fix the discrimination. Canada reneged on August 21, 2026, so the duties took effect August 22, 2026. New action: Finding Canada still hasn't revoked its discriminatory dairy quota measures, Trump now excludes certain Canadian dairy 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 dairy products remain subject to duties as set in a separate, same-day proclamation modifying the dairy tariff scope. Implementation: U.S. Customs and Border Protection, in consultation with Treasury, Commerce, and the U.S. Trade Representative, will administer the ban and make 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.
