1. The US 50% Duty on Canadian Goods Now Covers the Box Your Product Ships In
The covered list includes corrugated boxes, kraft linerboard, plastic film and plywood.
If a Canadian mill supplies your boxes, bags, stretch film or pallet plywood, or the importer behind your distributor does, that packaging has carried an extra 50% duty since August 22, on top of the duties it already paid.
The duty rests on a 1930 trade law that lets the president penalize a country he finds is discriminating against US commerce. Three July 20 proclamations used it against Canada. Their titles named alcohol, dairy and motor vehicles, but the annexes behind them are broad lists, and the president changed the list effective September 15. It now includes corrugated cartons and boxes, sacks and bags, uncoated kraft linerboard, plastic packaging and film, plywood and wood panels, some aluminum products and dissolving pulp. Folding cartons and other grades of pulp are not on it. The import bans that took effect September 29 are narrower: whey, molasses and sugar syrups, alcohol and beverages, and motorcycles. No paper.
The duty stacks on top of the normal rate and any extra duties on goods sold below fair price, and it applies on the date goods enter the United States, so cargo that was still at sea on August 22 paid the 50% when it entered the country. Sandler Travis & Rosenberg, a trade-law firm, and GHY, a customs broker, read the proclamations as giving no relief to goods that qualify under the US-Mexico-Canada trade agreement, and none of the proclamations carves them out. Canada supplied $6.59 billion of US paper and paperboard imports in 2025, according to Printing United Alliance, the printing and packaging trade association, and Canada has answered with C$27.6 billion, about US$20 billion, in counter-tariffs that include pulp, paper and plastics. No lawsuit challenging the law had been filed as of September 28, according to Law News, and the US Trade Representative said October 1 that talks continue but difficult issues remain.
