President modifies Canadian product scope for 50% auto duties
Effective Sep. 15, 2026, certain Canadian imports face a 50% ad valorem duty while others are removed from the levy
Proclamation 11065, issued Sep. 8, 2026, revises the product list covered by the additional 50 percent ad valorem duty imposed under Proclamation 11048. The revision applies to imports of Canadian goods and takes effect for goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. Eastern time on Sep. 15, 2026.
Annex I, Part A of the proclamation identifies the Canadian products that will now be subject to the 50 percent duty, while Annex I, Part B lists the products that are no longer subject to that duty. The duties remain in addition to any rates imposed under section 232 of the Trade Expansion Act of 1962. The Harmonized Tariff Schedule of the United States (HTSUS) is amended as set out in Annex II, with the same effective date, and the changes will remain in force unless expressly suspended, revoked, supplemented, amended, or terminated.
The heads of each executive department and agency are directed to take all appropriate measures to implement the proclamation. The Commissioner of U.S. Customs and Border Protection, in consultation with the Secretaries of Treasury and Commerce and the United States Trade Representative, may issue the necessary rules, regulations, guidance, or determinations. Any such rule requiring approval must obtain the President's or the Trade Representative's consent as delegated under 19 U.S.C. 1338(h).
The authority for the action derives from section 338 of the Tariff Act of 1930, which permits additional duties not to exceed 50 percent ad valorem, and from section 604 of the Trade Act of 1974, which allows the President to amend the HTSUS. Inconsistent provisions of prior proclamations and Executive Orders are superseded, and a severability clause preserves the remainder of the proclamation if any part is held invalid.
The proclamation appears in the Federal Register, Vol. 91, No. 176, pages 58339-58346, FR Doc No. 2026-18839, and binds importers of the specified Canadian products as well as the agencies charged with enforcement.
