What Changed
Effective February 12, 2025Effective February 12, 2025, Section 232 steel and aluminum tariffs were reimposed at 25% on all countries after a period where expanded tariff-rate quotas (TRQs) had been negotiated with the EU and other partners under the Biden administration. The Trump administration ended these quota arrangements and reimposed broad S232 tariffs as a baseline before subsequent increases to 50% in June 2025. This restored the Section 232 framework to a universal application without country-specific quota carveouts.
Rate Changes
| Item | Before | After |
|---|---|---|
| Steel (HTS 72, 73) — EU and others | TRQ arrangement (quota at 0%, over-quota at 25%) | 25% S232 (universal) |
| Aluminum (HTS 76) — EU and others | TRQ arrangement | 10% S232 (universal) |
Who's Affected
US steel and aluminum importers who had benefited from tariff-rate quota arrangements with the EU under the 2021 agreement. European steel exporters lost their preferential quota access. Downstream US manufacturers — automotive, appliance, construction — saw steel and aluminum input costs rise again after the TRQ arrangements were terminated.
Analysis
Section 232 Steel and Aluminum Tariffs Reimposed at 25% After 2021-2024 Suspension (effective 2025-02-12). Effective February 12, 2025, Section 232 steel and aluminum tariffs were reimposed at 25% on all countries after a period where expanded tariff-rate quotas (TRQs) had been negotiated with the EU and other partners under the Biden administration. Section 232 of the Trade Expansion Act of 1962 authorizes the President to impose tariffs or quotas on imports when the Department of Commerce determines that the import levels threaten to impair national security. The statute provides broad executive authority and has been used extensively since 2018 to cover steel and aluminum, with subsequent expansions to copper, automobiles, lumber, and semiconductors. Section 232 tariffs are notably permanent in character — unlike Section 122, they carry no statutory expiration and can remain in effect indefinitely once imposed. Products covered by Section 232 are exempt from the Section 122 surcharge under the February 2026 proclamation, meaning importers of S232-covered goods do not face double-stacking of these two tariff authorities. However, S232 rates do stack on top of MFN base rates, and China-origin products that fall under Section 301 may face additional tariff layers on top of S232. The expansion of Section 232 to cover copper in March 2025 and semiconductors in January 2026 reflects a broader industrial policy strategy to protect domestic manufacturing capacity in strategic sectors. Importers of S232-covered products should verify the exact HTS classification of their goods and confirm whether any country-specific exemptions or quotas apply to their sourcing country.
Impact & Next Steps
Manufacturers and importers of S232-covered products should work with licensed customs brokers to verify HTS classifications and ensure correct duty application. Country-of-origin documentation is critical: the S232 tariffs apply to the country where the product was substantially transformed, not simply where it was last shipped from. Some S232-covered products have product-exclusion processes through the Department of Commerce; check current exclusion orders before assuming the full rate applies to your specific product.
