U.S. Bans Selected Canadian Products and Targets $50 Billion in Canadian Goods Under Section 338

2.    Section 338 Invoked: President Trump exercised authority under Section 338 of the U.S. Tariff Act of 1930 to:

3.    Targeted Canadian Sectors: The new import bans primarily cover:

o    Motor vehicles

4.    Reason Cited by U.S.: The measures are intended to counter Canada's alleged discriminatory treatment of crucial U.S. exports, including vehicles, dairy and alcoholic beverages.

8.    Modification of Earlier Measures: The September action also refines the scope of the July 20, 2026 Section 338 measures, targeting strategic Canadian sectors while removing certain non-sensitive Canadian goods.

9.    Presidential Powers Under Section 338: Section 338 of the Tariff Act of 1930 (19 U.S.C. §1338) permits the President to impose duties of up to 50% on imports from countries whose discriminatory or unequal treatment disadvantages U.S. commerce.

10.  Import Bans Also Authorized: Section 338 allows the President to exclude products from U.S. importation where a foreign country maintains or increases discriminatory practices against U.S. commerce.

On 8 September, 2026, Ambassador Jamieson Greer issued a statement after President Trump exercised his authority under Section 338 of the Tariff Act of 1930 to ban certain Canadian products from entering the U.S. market and modify the scope of the July 20 actions to effectively offset the burden or disadvantage to U.S. commerce by Canada’s discriminatory measures.

“After weeks of good faith and intensive efforts between U.S. and Canadian negotiators, Canada walked away from a near-final trade deal that offered better treatment than any other trading partner, and instead Canada chose to embark on senseless retaliation against the United States,” said Ambassador Greer. “Today’s action, combining targeted import bans as authorized by Section 338 and a calibration of the underlying Section 338 tariffs, is a natural consequence of Canada’s continued discriminatory treatment of crucial American exports, ranging from alcoholic beverages to dairy products to motor vehicles. President Trump will continue to leverage the tools at his disposal to defend the interests of American workers and exporters, and restore reciprocity in our bilateral trade relationships.”

Additionally, the President has directed USTR (Office of the United States Trade Representative) and GSA (General Services Administration) to remove $50 billion dollars’ worth of Canadian-origin products from GSA’s Multiple Award Schedules.

Background:

Section 338 of the Tariff Act of 1930 (19 U.S.C. 1338) empowers the President to, among other things, impose duties of up to 50 percent on imports of a foreign country to offset the burden or disadvantage from a foreign country’s unequal imposition on or discrimination against the commerce of the United States. On July 20, 2026, finding that the public interest will be served by his actions, President Trump took three separate Section 338 actions to level the playing field for important American exports to Canada—motor vehicles, alcoholic beverages, and dairy. Section 338 further empowers the President to exclude products from importation into the United States if a foreign country maintains or increases its discriminatory practices against U.S. commerce.

Based on Canada’s continued retaliation and discrimination against U.S. commerce, President Trump has determined that it is necessary and appropriate to ban certain Canadian products from entering the U.S. market and refined the scope of the July 20 actions to target strategic Canadian sectors while removing certain non-sensitive Canadian goods from the scope of the actions.
