Should the US lower tariffs on Canadian aluminum to reduce costs?
Canadian aluminum producers expressed optimism that US tariffs on their metal could be reduced following Democrats' control of both chambers of Congress in the November 3 midterm elections. The existing 50% Section 232 tariff remains in effect, and no formal agreement or revised tariff schedule has been announced.
Why it matters
The political shift could increase pressure on the Trump administration to resume trade negotiations with Canada. Tariff relief could improve cross-border trade flows and exert downward pressure on the US Midwest aluminum premium, though any adjustment could be gradual.
The US Midwest aluminum premium eased to approximately US$1.12/lb on November 4, down from a record US$1.19/lb in late May 2026. Canada's share of US aluminum imports has declined to about 62%, compared with an average of 74% during 2020-2024, and it remains unclear how far the premium will move if tariffs are eased.
The players
Democratic Party
The Democratic Party won control of both chambers of Congress in the November 3, 2026 midterm elections, a shift that could influence the trade policy environment.
Trump administration
The administration of President Donald Trump imposed the Section 232 tariff on Canadian aluminum and may face renewed pressure to resume negotiations with Canada.
The details
Canadian producers are redirecting shipments towards Europe as the 50% tariff continues to weigh on US sales. Imports account for more than 80% of US primary aluminum consumption, leaving the US market dependent on foreign supply.
Timeline
November 3, 2026: US midterm elections held, with Democrats winning control of both chambers of Congress.
Late May 2026: US Midwest aluminum premium reached a record US$1.19/lb.
November 4, 2026: US Midwest aluminum premium eased to approximately US$1.12/lb.
Market Dynamics
The Section 232 aluminum tariff continues to shape how Canadian supply reaches the US market, with Canada's share of US imports now falling to about 62%. Any move to ease the 50% rate would reverse a trend in which Canadian producers have been redirecting volume toward Europe.
Investors with exposure to aluminum prices or Canadian metals producers should monitor whether tariff negotiations resume and how the US Midwest premium responds. No formal agreement has been reached, so the timing and extent of any change remain uncertain.
The takeaway
Tariff policy on Canadian aluminum remains unsettled despite the shift in Congress, so readers should watch for formal trade negotiations before assuming relief. Monitoring the US Midwest premium can offer an early read on whether market expectations are moving.
