Imposing Additional Duties To Offset Canadian Discrimination Against the Commerce of the United States With Respect to Motor Vehicles

This proclamation imposes an additional 50 percent ad valorem duty on certain Canadian products, effective August 19, 2026, to offset Canada's discriminatory tariff scheme against U.S. motor vehicles. The action uses Section 338 of the Tariff Act of 1930 to retaliate against Canadian tariffs and tariff-rate quotas that apply only to U.S. auto exports, which have allegedly caused a 22 percent drop in U.S. vehicle exports to Canada.
