The U.S. Commerce Department has created a pathway for Canadian and Mexican steel and aluminum producers serving U.S. vehicle manufacturers to cut Section 232 tariffs from 50% to 25% if they make binding commitments to build or expand primary metal production facilities in the United States.
Key Takeaways
-
Tariff cuts tied to U.S. investment: Qualifying Canadian and Mexican producers can halve their Section 232 tariff rate by committing to build or expand U.S. plants producing primary steel or aluminum for automakers and medium- and heavy-duty vehicle manufacturers.
-
Strict eligibility and documentation: Applicants must already supply U.S. vehicle makers, have exports that qualify under the USMCA, and submit a senior officer–certified filing detailing plant locations, products, customers, raw material sources and a full overview of the planned U.S. facility.
-
Milestones and volume limits apply: The lower tariff only covers volumes equal to the projected annual output of the new U.S. facility and for a fixed period, with companies required to meet specific project milestones such as land purchase, design completion, construction and the start of production.
