As previously reported, on August 22, 2026, Canadian Prime Minister Mark Carney announced that Canada will impose dollar-for-dollar retaliatory tariffs in response to the Section 338 additional duties that went into effect following the suspension of trade negotiations between the U.S. and Canada.
On August 25, 2026, the Canadian Government unveiled the finalized list
In the latest development in United States-Canada trade relations, 50% additional duties, announced in three separate proclamations issued on July 20, 2026, took effect as of 12:01 a.m. eastern time on August 22, 2026. President Donald Trump imposed the additional duties pursuant to Section 338 of the Tariff Act of 1930, which empowers the President to impose additional duties (not exceeding 50%) on imports from a foreign country to offset the burden or disadvantage caused by that country’s unequal imposition on or discrimination against U.S. commerce.
The Trump Administration has officially reduced tariffs on patented pharmaceuticals and associated pharmaceutical ingredients imported from the United Kingdom (UK) from 10% to 0%. This change, effective July 31, 2026, is the result of an agreement between the United States and the UK, which created a carve out for UK origin pharmaceutical products from the recent national security tariffs imposed on patented pharmaceuticals pursuant to Section 232 of the Trade Expansion Act of 1962 (Section 232).
On August 4, 2026 the Bureau of Industry and Security (BIS) published a notice seeking public comments on expanding tariffs applicable to certain steel, aluminum and copper derivative products under Section 232 of the Trade Expansion Act of 1962 (Section 232) to fourteen (14) additional derivative products.

On August 3, 2026, the state attorney generals of twenty-five states (25) co-led by State of Oregon, Arizona and California filed a complaint in the Court of International Trade (CIT) challenging tariffs imposed under Section 301 of the Trade Act of 1974 (Section 301) to address forced labor. The complaint alleges that Section 301 forced labor tariffs are ultra vires, arbitrary, capricious and contrary to law.
This complaint by the 25 state attorney generals challenging the legality of the Section 301 forced labor tariffs, joins other lawsuits pending before the CIT that were filed by small business plaintiffs, Burlap and Barrel, Inc. and Collective Horology LLC.
On July 28, 2026, the U.S. Department of Commerce (Commerce) published a federal notice stating that U.S. manufacturers of engines for cars and medium- and heavy-duty trucks (MHDVs) can now receive tariff offsets for sectoral duties on imported parts. The U.S. International Trade Administration said the new process sets rules similar to the offsets announced in May for vehicle makers that use imported parts.
On July 20, 2026, President Trump issued a new Presidential Proclamation aimed at further strengthening the U.S. aluminum industry. The latest Proclamation builds upon the existing Section 232 aluminum tariff regime by introducing a strategic investment incentive program designed to bring primary aluminum production back to the United States.
