Duties, tariffs and fees
Section 232
Section 232 duties are tariffs on imports that threaten to impair U.S. national security. The President imposes them after a Commerce Department investigation.
What does Section 232 mean?
Section 232 of the Trade Expansion Act of 1962 (19 U.S.C. 1862) lets the President adjust imports that threaten to impair national security. The Secretary of Commerce investigates first, and the President acts by proclamation.
In September 2026, CBP lists Section 232 duties on steel, aluminum, copper, automobiles and parts, medium and heavy-duty vehicles, and timber and lumber. The list also includes semiconductors, patented pharmaceuticals and unmanned aircraft systems.
Entries report Section 232 duties with Chapter 99 numbers. For steel and aluminum products, the entry also reports the country of melt and pour or the country of smelt and cast.
Agreements with the United Kingdom, Japan, the European Union and Korea changed some Section 232 duties on automobiles and parts. The Section 122 surcharge did not apply in addition to Section 232 duties.
What does it mean for your shipment?
Ask your supplier for the metal content, the country of melt and pour, and the country of smelt and cast before the goods ship. We need this data to file steel and aluminum entries.
