The White House issued a formal proclamation on July 20, 2026, placing additional import duties on Canadian goods tied to the dairy sector.
The administration said the tariffs are meant to offset what it characterized as Canadian discrimination against U.S. dairy commerce. The legal basis is Section 338, codified at 19 U.S.C. 1338, a provision of the Tariff Act of 1930 that grants the President authority to levy duties on imports from countries found to treat U.S. commerce unequally or in a discriminatory manner.
The proclamation was issued from the White House in Washington, D.C.
