The Trump administration is considering overhauling U.S. steel and aluminum tariffs—keeping 50% duties on commodity imports from Canada and Mexico while cutting derivative product tariffs to 15%–25%. Crucially, duties would now apply to the full value of finished goods, not just metal content. With $154.9B in 2025 metal imports—and $15.7B from Mexico alone—the policy threatens to raise costs across integrated North American supply chains, especially in automotive, appliances, and construction. Laredo, TX, the top U.S.–Mexico trade gateway for metal goods, faces heightened compliance and cost pressures. Revenue projections estimate $70B raised through FY2036.
According to www.freightwaves.com, the Trump administration is considering a major revision of its steel and aluminum tariff regime — one that would maintain 50% tariffs on commodity steel and aluminum imports from top U.S. trade partners including Canada and Mexico, while reducing duties on derivative metal products to 15%–25%, depending on the item.
Key Policy Shifts
The proposed changes, expected via presidential proclamation, would fundamentally alter how tariffs are calculated: duties would apply to the full value of imported derivative goods — such as auto parts, tractors, stainless steel sinks, and gas ranges — rather than only the embedded steel or aluminum content. This change aims to simplify compliance but may substantially raise import costs for finished and semi-finished goods entering the U.S. from Canada and Mexico.
Impact on Cross-Border Supply Chains
In 2025, the U.S. imported approximately 13% of its steel and 60% of its aluminum consumption, with total metal imports (iron, steel, aluminum, copper) valued at $154.9 billion, slightly down from 2024. Top sources included Canada ($27.2B), China ($18.5B), Mexico ($15.7B), Chile ($9.12B), and South Korea ($7.66B), per the Observatory of Economic Complexity.
These flows underpin deeply integrated North American manufacturing networks — especially in automotive and industrial sectors — where raw metals may be melted in the U.S., rolled or processed in Mexico, and assembled into final products through multiple border crossings. Laredo, Texas, serves as the largest U.S. trade gateway for steel-containing manufactured goods moving between the U.S. and Mexico.
Industries and Products Affected
- Automotive manufacturing
- Heavy equipment and machinery
- Appliances and HVAC
- Construction materials
- Energy equipment and pipelines
Derivative products already subject to Section 232 tariffs include auto parts, tractors, industrial machinery, steel sinks, and household appliances. The shift to full-value assessment means even U.S.-origin metal re-exported as part of a Mexican-assembled component could trigger duties on the entire product’s landed value — not just its metal share.
Fiscal and Regulatory Context
The overhaul is tied to federal revenue goals. One estimate by the Committee for a Responsible Federal Budget projects the changes could generate $70 billion in revenue through fiscal year 2036, helping offset losses after the Supreme Court curtailed the administration’s tariff authority under emergency powers. The Trump administration had previously expanded Section 232 tariffs last year — doubling steel and aluminum duties to 50% and extending them to thousands of derivative products.
