U.S. exports of alloy pig iron and spiegeleisen (HS 720150) totaled $135K in December 2025, traded with 1 country.
Alloy pig iron and spiegeleisen — a manganese-rich iron alloy historically used as a deoxidizer and desulfurizer in steelmaking — occupy separate 10-digit lines (7201503000 and 7201506000) within this heading. Spiegeleisen, named for its mirror-bright fracture surface, typically contains 15–30% manganese and is now largely supplanted by ferromanganese in modern steelmaking, making it a specialty import. Italy is the recorded top supplier, consistent with European specialty metallurgical production. Both products are subject to Section 232 tariffs as primary iron forms.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Spiegeleisen (7201506000) is classified as a pig iron because it is produced in a blast furnace and contains significant carbon alongside manganese, whereas ferromanganese (heading 7202) is a ferroalloy produced specifically to deliver manganese as an alloying addition. The key classification test is the production process and the relative proportions of iron, manganese, and carbon; when manganese content is high enough to meet the ferroalloy definition, heading 7202 takes precedence.
Yes. Section 232 steel and iron tariffs apply to pig iron in primary forms regardless of alloy content. Importers should confirm current country-specific exclusion status with CBP or a licensed customs broker, as the tariff landscape for iron and steel products has evolved through successive proclamations and exclusion processes.
