Banned, Not Taxed: Starting September 29 Canadian Beer, Wine, Spirits, Whey and Big-Engine Motorcycles Cannot Enter the U.S. at Any Price, While Ottawa's Own 50% Tariffs on $20 Billion of American Goods Took Effect the Same Morning

For the first time in this trade war, the United States is refusing Canadian goods rather than charging for them. On Tuesday, September 8, President Trump signed five proclamations under Section 338 of the Tariff Act of 1930. Three of them exclude specific Canadian products from importation entirely, effective 12:01 a.m. Eastern on September 29. Two more rewrite the list of Canadian goods that pay a 50% tariff, effective September 15. The White House also ordered the General Services Administration to strip Canadian-origin products from its Multiple Award Schedules, the catalog behind more than $50 billion in federal procurement. The proclamations landed hours after Canada's retaliatory tariffs on about $20 billion of U.S. exports took effect at 12:01 a.m. that morning.

What is banned from September 29

The exclusions cover three product families that the July 20 proclamations had already hit with 50% duties. Alcoholic beverages: beer, wine, cider and other fermented drinks, high-proof beverage alcohol and most major spirits categories. Dairy-adjacent goods: whey products, molasses and non-alcoholic beer. Motor vehicles: motorcycles, mopeds and cycles with internal-combustion engines above 800 cubic centimeters. Trade economist Deborah Elms of the Hinrich Foundation put the value of the banned lines at less than $1 billion in trade value. Goods that cross before September 29 but have not yet been entered for consumption stay at the 50% rate rather than being refused. If a court strikes the ban on any product, the 50% duty snaps back automatically; the proclamations say so.

The September 15 reshuffle matters to more shippers than the ban. Added to the 50% list: specialty cheeses and additional dairy products, modified fats and oils, bovine hides and upholstery leather, certain raw and dressed furskins, recreational motorboats, all-terrain vehicles, specialty paper, some steel and aluminum items, metal fittings and welding inputs, golf carts, furniture and lamps. Removed: rock salt, cement, toilet paper, and whiskies, liqueurs and cordials in containers over four liters. The White House fact sheet is explicit that the Section 338 duties apply whether or not a good qualifies under USMCA and stack on top of existing Section 232 tariffs. Elms called the net change "basically a wash" in dollar terms, with the caveat that "if your firm produces the goods now added to any list, it's impactful."

How it got here

The July 20 proclamations found Canada to be discriminating against U.S. alcohol, dairy and motor-vehicle exports and set 50% tariffs to take effect August 19. On August 18 the White House suspended them for three days after Canada signaled it would remove the measures. Talks collapsed on August 21, the suspension lapsed at 12:01 a.m. on August 22, and the tariffs went live on roughly $20 billion to $28 billion of Canadian imports, depending on whose count is used. Canada answered with duties of 15%, 25% and 50% on hundreds of U.S. products, including steel and aluminum at 50%, cheese, appliances, clothing, cosmetics and farm equipment. Ottawa calls it dollar-for-dollar; the roughly $20 billion covered equals about 6% of the $333.6 billion the United States exported to Canada in 2025. Imports from Canada that year were $381.9 billion.

Prime Minister Mark Carney's response was to accept the pain and speed up decoupling. "We will do whatever it takes for as long as it takes," he said Tuesday, and later: "It was easy business, but it meant we relied too much on one economic partner. That time is over." More than 70% of Canadian exports still go to the United States. Carney is due in Strasbourg next week for the European Commission president's State of the Union address on September 16 and will address the European Parliament the following day, and a Canadian official said Ottawa is exploring ties with the European Union short of membership. Trade Minister Dominic LeBlanc said he remains in contact with U.S. Trade Representative Jamieson Greer, and a senior U.S. official told reporters the two sides had "constructive conversations" and would talk again within days.

What cross-border carriers see

FreightWaves' SONAR index of outbound tender volumes from Canada to the United States has fallen more than 16% since Sunday after surging at the end of August, when shippers pushed freight across ahead of the retaliation date. FreightWaves attributes a big part of the drop to the U.S. Labor Day holiday on Monday. The wider exposure for carriers is on the U.S. export side: steel, aluminum, dairy, appliances and farm equipment heading north now carry Canadian duties of 15% to 50%. Southbound, the banned categories are small in dollar terms, under $1 billion by Elms's estimate, so the direct hit lands on the carriers that specialize in beverage, dairy and powersports freight rather than on the border as a whole.
