President Trump and U.S. Trade Representative Jamieson Greer waited to see if Canada was going to follow through with their retaliatory tariffs against U.S. imports.

The Canadian government carried out their tariffs, so today the White House introduced 50% ‘stacking tariffs’, on top of pre-existing tariff rates, and additional import bans against several Canadian products.

It should be quickly noted that several North American corporations are already making moves to avoid the issues by shifting production lines and adding additional investment into U.S. manufacturing.  As expected, getting locked out of a 32 trillion economy is not an option for survivability.

The easiest way to review the issues is not to read media reports, but rather to read the actual outcomes as announced by the White House and USTR.  CTH has noticed several Canadian outlets are already making false claims.

It is worth reviewing both sets of outlines as well as accompanying links to determine the exact types of Canadian products being targeted by stacking tariffs and import bans.

WHITE HOUSE – Today, to address Canada’s increased discrimination against U.S. commerce, President Trump signed five Proclamations pursuant to Section 338 of the Tariff Act of 1930 to ban certain products from Canada and modify the scope of the tariffs on certain Canadian products previously announced on July 20, 2026. President Trump is taking decisive and appropriate action to respond to Canada’s additional retaliation and continued discriminatory treatment of crucial American exports.

• After breaking off trade talks with the United States last month, today Canada imposed new retaliatory tariffs on about $20 billion of U.S. exports, including steel, dairy, and agricultural equipment.

• Because Canada maintained and in fact increased its discrimination against U.S. commerce with respect to U.S. alcoholic beverages, President Trump, under Section 338, imposed import bans on certain Canadian alcohol and other products that were subject to the 50 percent tariffs imposed under Section 338 in Proclamation 11046.

• Moreover, because Canada maintained its discrimination against U.S. commerce with respect to dairy, President Trump, under Section 338, imposed import bans on certain Canadian dairy and other products of Canada that were subject to the 50 percent tariffs imposed under Section 338 in Proclamation 11047.

• To offset the burden to U.S. commerce while better serving the public interest, President Trump is also modifying the July 20, 2026 actions by removing certain products, such as rock salt and cement, from the scope of the Section 338 tariffs and replacing those products with new ones, ranging from all-terrain vehicles (ATVs) to additional dairy products.

• These Section 338 tariffs apply to all covered goods regardless of whether a good originates under the U.S.-Mexico-Canada Agreement (USMCA) and apply in addition to tariffs imposed under Section 232 of the Trade Expansion Act of 1962.

• The import bans will take effect on September 29, 2026, and the product additions and removals will take effect on September 15, 2026.

WASHINGTON – Today, 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. {Source}

It appears that some of the product categories would be limited by ‘stacking tariffs’, as a consequence the U.S. is simply moving to ban the products altogether.
