Tariff resources

While NAFEM regularly updates this resource page, we recommend regular communication with your customs broker for up-to-the-minute tariff information relative to your business and its products.

Customs and Border Protection has a helpful one-page fact sheet summarizing all tariffs.

U.S. steel and aluminum tariffs

• Steel and aluminum products (including derivatives) – regardless of country of origin – are subject to a uniform 25% Section 232 (national security) tariff. No extensions or exclusions apply, effective March 12. Only exception is aluminum from Russia, which is subject to 200% tariff.
• For steel and aluminum imports from China, tariffs are cumulative, including the above 25% from March 12 + International Emergency Economic Powers Act (IEEPA) tariffs of 10% from March 4, 2025 and 10% from Feb. 1, 2025. De Minimis no longer available effective May 2.

• Imports from China, Hong Kong and Maca are subject to a 125% tariff.
  • Customs and Border Protection (CBP) posted a message exempting certain electronic products, items and components from the IEEPA reciprocal tariffs. The exemptions are applied based on HTS codes included in the link.
• Imports from Canada and Mexico
  • 25% tariff on imports of all products of Canada and Mexico.
    • 10% on Canadian energy products and potash
    • 10% on Mexican potash
    • Automobile production and products qualifying under the USMCA are exempt.

Additional U.S. investigations

• The U.S. Department of Commerce opened a brief three-week comment period (April 16 – May 7) on its Section 232 investigation of the security risks of imports of semiconductors, semiconductor manufacturing equipment and their derivative products. The investigation also covers semiconductor substrates and bare wafers, legacy chips, leading-edge chips, microelectronics and manufacturing equipment components. The final report is due to President Trump Dec. 27, although the administration has stated its intent to move at a faster pace.
• Despite possessing ample copper reserves, America’s smelting and refining capacity lags far behind global competitors. President Trump initiated a Section 232 investigation to assess U.S. national security risks arising from the country’s increasing dependence on imported smelted and refined copper. Findings are due Nov. 22. 
• A similar Section 232 investigation is underway for imports of timber, lumber and their derivative products. According to the White House, “current United States softwood lumber industry has the practical production capacity to supply 95% of the United States’ 2024 softwood consumption. Yet, since 2016 the United States has been a net importer of lumber.” Findings are due Nov. 26. 
• Following a Section 301 investigation of China’s targeting dominance in the maritime, logistics and shipbuilding sectors, the U.S. Trade Representative proposed significant service fees on China-bult vessels upon entrance to U.S. ports. NAFEM, the U.S. Chamber of Commerce and 100+ others advocated against the proposal that would increase shipping costs, raise prices and decrease exports and imports.
