Washington Can't Raise Its Canada Tariff Rate — So It Re-Cut the Product List Eleven Days Before the Midterms

The Oct 23 proclamation removed plywood sheets, some paper products, certain machinery, refrigeration equipment and packing crates from the 50% Section 338 list, and added certain valves, carpets and waste products in their place. It strips 50% duties from five product groups and adds three others, effective Oct 30. Covered goods pay the Section 338 duty whether or not they qualify under USMCA, and it stacks on top of existing Section 232 duties.

The reason is electoral. Senator Susan Collins of Maine announced the exemptions and argued they would protect blueberry, potato, apple and seaweed growers; her Democratic challenger Troy Jackson answered that Trump's trade wars had made life harder and more expensive for Mainers. CTV News reported the White House moved the change specifically to boost Collins' re-election campaign, and reported that Trump was facing lagging polls about ten days out. The carve-out lands 11 days before the midterms with a named beneficiary.

The legal architecture has been rebuilt twice in eighteen months. IEEPA tariffs were terminated on Feb 24, 2026; the administration then used Section 122 of the Trade Expansion Act of 1962 to impose a 10% surcharge on most imports for 150 days from the same date. When that window ran out, the White House reached for Section 338 of the Tariff Act of 1930, a statute unused for 96 years that authorises tariffs of up to 50% against a country judged to discriminate against US commerce. The statute caps the rate at 50% and had gone unused for 96 years. Section 338 duties on Canadian goods took effect Aug 22, 2026.

On Oct 20 the Liberty Justice Center filed suit at the Court of International Trade for Gellert Global Group, arguing that Section 338 was superseded by Section 301 of the Trade Act of 1974, that the products covered were not tied to the discrimination alleged, and that the September addition of specialty cheeses skipped the statute's mandatory 30-day waiting period. It asks the court to strike down the levies, block collection and order refunds. Because the rate is pinned and the statute is contested, escalation migrates to the schedule — and the schedule is what gets rewritten.

The carve-out moves different companies in opposite directions. Carpets went on the list while plywood and refrigeration equipment came off, so a US flooring maker and a US appliance maker feel the same proclamation in reverse. Carpet joined the 50% list while plywood and refrigeration came off — one schedule, opposite sign.

Note what is missing from both sides. Canada focused its counter-tariffs on steel, dairy, appliances, agricultural equipment, pulp and paper and electronics, and the Oct 23 proclamation touched neither power nor energy. Neither government has put electricity on a counter-tariff line, which leaves Canadian hydro and gas exports as the reserve that has not yet been spent.

Tariffs are not a footnote in these earnings; they sit in the gross margin line, and they separate the companies cleanly. Gross margins moved in opposite directions on the same policy. US metal and vehicle producers gained; the companies that ship product across the 49th parallel in both directions lost.

Two of these deserve emphasis. Magna International posted a small net loss in Q1 2026 before returning to $457 million of profit in Q2, and its gross margin fell 320 basis points year over year. Whirlpool booked an $85 million net loss in Q1 2026, and a Q2 gross margin of 12.6% leaves no cushion for a Canadian duty on US-made appliances. The names with the biggest margin compression all ship product across the 49th parallel in both directions.

Ottawa holds a card it has not played. Suncor Energy reported Q2 2026 revenue of C$19.0 billion against C$12.0 billion a year earlier, with net income of C$3.73 billion against C$1.13 billion and earnings per share of C$3.17 against C$0.93. Quarterly revenue rose 58% year over year, which means the barrels Canada sends to the United States are worth materially more in 2026 than they were in 2025.

The infrastructure that delivers them is regulated and long-dated. TC Energy runs roughly 4,900 kilometres of liquids pipeline carrying crude from Alberta to refining centres in Illinois, Oklahoma, Texas and the US Gulf Coast, alongside a 93,300-kilometre natural gas network and seven generating plants of about 4,300 megawatts in Alberta, Ontario, Québec and New Brunswick. It reported Q2 2026 revenue of C$3.99 billion, gross profit of C$2.01 billion and net income of C$987 million against C$833 million a year earlier. Ottawa can afford to wait longer than Washington can afford to look resolved: Carney said there was no merit to the election-interference claims, that Canada would never be the 51st state, and that if a proper deal took months or a change of administration, Ottawa would wait.

The sequencing matters for position sizing. Nothing about the next 60 days requires a binary call on Canada. It requires a view on which product lines sit inside the list, and on the two dated step-ups — the Oct 30 rewrite and the Jan 1 furniture and cabinet duties.
