President Donald Trump on Friday modified which Canadian products face an extra 50 percent import duty tied to a dispute over Canada’s motor vehicle tariff scheme. The proclamation says the changes aim to continue offsetting what the President previously found to be discrimination against United States commerce with respect to motor vehicles.
The action affects certain Canadian goods that will no longer face the additional duty and others that will now face it, as detailed in Annex I to the proclamation. The document did not say how many products are affected. The proclamation says the additional duties remain intended to “offset the burden or disadvantage on U.S. commerce.”
The changes take effect for goods entered or withdrawn from warehouse for consumption on or after 12:01 a.m. eastern time on Oct. 30, 2026. The additional duty is set at 50 percent ad valorem and applies in addition to duties imposed under section 232 of the Trade Expansion Act of 1962, according to the proclamation.
The proclamation cites section 338 of the Tariff Act of 1930, which allows the President to impose and modify additional duties to counter unequal foreign measures when doing so serves the public interest. It also invokes section 604 of the Trade Act of 1974 to make changes to the Harmonized Tariff Schedule of the United States in Annex II.
Senior executive branch officials advised that adjusting the scope of covered products would still offset the burden on U.S. commerce and better serve the public interest, according to the proclamation. After considering those views, the President determined the public interest requires the modification.
The action follows Proclamation 11048 of July 20, 2026, which first imposed the additional duties after findings that Canada’s measures discriminate against U.S. commerce; a three-day suspension under Proclamation 11056 in August; and subsequent updates under Proclamation 11065 in September. The suspension lapsed on Aug. 22, 2026, and the duties took effect at that time, the proclamation says.
U.S. Customs and Border Protection, in consultation with the Departments of the Treasury and Commerce and the United States Trade Representative, is authorized to issue rules, guidance, and determinations to implement the proclamation. The CBP Commissioner is also directed to make any needed technical or ministerial updates to the tariff schedule by notice in the Federal Register. Any inconsistent prior proclamations or executive orders are superseded to the extent of a conflict, according to the document.
