Trump Reshuffles 50% Canada Tariff List, Effective Oct. 30

President Trump signed a proclamation on Oct. 23, 2026, changing which Canadian goods face the additional 50% duties imposed under Section 338 of the Tariff Act of 1930. The White House says the revised product scope takes effect Oct. 30, 2026.

The order removes plywood sheets, some paper products, certain machinery and packing crates from the duties, and adds valves, carpets and waste products. Trade coverage also names cocoa powder and vinyl flooring among the additions; those two items do not appear in the White House list.

Which Products Leave the List and Which Join It

The White House lists plywood sheets, some paper products, certain machinery, certain refrigeration equipment and certain packing crates and boxes among the removals. A 24/7 Wall St. report on Oct. 24, 2026 adds blueberry harvesting boxes to the crate category.

Reporting differs on the additions. Supply Chain Dive, as republished by Yahoo News on Oct. 23, 2026, names cocoa powder, carpets and air conditioners. 24/7 Wall St. names cocoa powder, vinyl flooring, shampoos and carpets. Yahoo's air conditioner entry may conflict with the White House removal of refrigeration equipment. The White House list names valves, carpets and waste products as additions and refers to other unnamed goods.

CBP guidance is still pending, according to a GHY trade-compliance report, which points readers to ANNEX 1 and ANNEX 2 of the proclamation for the revised product lists. GHY also notes that duty is based on entry date, so timing entries around Oct. 30 matters.

How the Duties Stack on Section 232 and Treat USMCA Goods

The White House says the Section 338 duties apply in addition to tariffs imposed under Section 232 of the Trade Expansion Act of 1962. The same order applies the duties to covered goods whether or not they originate under the U.S.-Mexico-Canada Agreement, a treatment GHY describes as unchanged from the original duties.

The White House ties the action to Canada's trade conduct. Its Oct. 23 fact sheet cites Canada's discriminatory treatment of U.S. commerce, Canada's decision to walk away from a near-final trade deal, and retaliatory tariffs on about $20 billion of U.S. exports. The fact sheet also says the changes protect American farmers, manufacturers and workers.

Reactions From Trump, Maine's Senator and Ottawa

Trump said Canada is working hard to make a deal but that the United States holds the leverage, according to 24/7 Wall St. In the proclamation, as Supply Chain Dive reported, he changed the list after senior executive branch officials advised that the change would still offset the alleged discrimination while serving 'the public interest.'

Sen. Susan Collins (R-Maine) announced the relief herself, saying nine categories of imports used by Maine growers and seaweed harvesters are now exempt, per 24/7 Wall St. Sen. Ron Wyden (D-Ore.) called the move a “desperate, 11th hour attempt” to save Collins’ career. Prime Minister Mark Carney said Canada could sign a deal this afternoon if the U.S. were there.

Trade lawyer Robert Glasgow told 24/7 Wall St. that more items were added than removed and expects a relatively small impact in the immediate term.

Separately, the Liberty Justice Center filed suit in the U.S. Court of International Trade the same week on behalf of Gellert Global Group. As Supply Chain Dive reported, the complaint argues Trump did not meet Section 338's requirements and asks the court to remove the tariffs, block their collection and order refunds. These are allegations, and no ruling has been reported.

What Happens Before and After October 30

The scope changes take effect Oct. 30, 2026. CBP guidance is still pending, according to GHY, which advises importers to re-screen their Canadian HTSUS lines against the revised product lists before Oct. 30.

GHY notes that duty is assessed by entry date, which means shipments entering on either side of Oct. 30 may face different treatment. No ruling in the Court of International Trade case has been reported.
