Steel and ferroalloy imports broadly fall within the scope of Section 232 national security tariffs. The applicable duty depends on the specific product form and the country of origin; some countries have negotiated quota arrangements or exemptions. Importers should consult a licensed customs broker to determine current treatment for their specific HTS subheading.

Ferroalloy production involves smelting iron with alloying elements such as manganese, chromium, silicon, or nickel to create master alloys used as additive inputs in steelmaking. Unlike integrated steel mills that produce finished steel, ferroalloy plants supply intermediate materials that control the chemical composition and mechanical properties of the final steel product.
