In a series of Presidential Proclamations published on July 20, 2026, President Trump announced the imposition of additional duties of 50% under Section 338 on certain Canadian dairy, alcoholic beverages, and motor vehicle products.
Section 338 authorizes the President to “offset any burden or disadvantage placed on the commerce of the United States by an unequal imposition or discrimination by a foreign country by specifying and declaring additional duties.”
Each proclamation includes an annex which lists the tariff classifications subject to the additional 50% duty rate. The Section 338 duties will not apply to products that are subject to existing Section 232 duties.
These Section 338 duties will apply to the specific Canadian goods that are entered for consumption, or withdrawn from a warehouse for consumption, on or after 12:01 a.m. Eastern Time on August 19, 2026.
