The United States imports substantial quantities of articles of iron or steel from Mexico, with approximately $779B in total bilateral trade.

The current tariff framework for articles of iron or steel from Mexico reflects the post-SCOTUS landscape: a 10% Section 122 tariff replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The Section 122 tariff is subject to a 150-day statutory time limit and is set to expire approximately July 24, 2026, unless Congress acts to extend or replace it. Importers should monitor legislative developments closely as this deadline approaches.

Products in this chapter may be subject to Section 232 tariffs of 50% on steel and aluminum items, which were doubled in June 2025 and remain unaffected by the SCOTUS ruling. When applicable, the combined rate reaches 60%.

Mexico is party to the USMCA, which may provide preferential or duty-free access for qualifying articles of iron or steel. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 73 imported from Mexico include Steel structures, Steel containers, Screws and bolts, Steel springs, Wire fencing, and Steel nails.
