U.S. imports of ferrosilicon manganese (HS 720230) totaled $41.4M in August 2026, imported from 15 countries.
Importers of Ferrosilicon Manganese paid $1.4M in duties in August 2026, an effective tariff rate of 3.40% of the $41.4M imported — duty actually collected as a share of that value, not the published tariff schedule. Ferrosilicon Manganese imports of $41.4M in August 2026 ran 17% above the year-to-date monthly average of $35.5M.
Last updated: August 2026 dataFerrosilicon manganese is a combined deoxidizer and alloying agent used in steelmaking to simultaneously introduce manganese and silicon, improving strength and toughness. Classified under a single 10-digit line (7202300000), it competes with separate ferromanganese and ferrosilicon additions, making the choice between them a cost and specification decision for melt shops. Malaysia leads US import supply, followed by South Africa and Georgia, reflecting the geographic concentration of both manganese ore and smelting capacity. Importers should monitor Section 232 exposure, as ferroalloys entering under Chapter 72 may be subject to steel-related trade measures.

Ferrosilicon manganese delivers both manganese and silicon in a single addition, reducing the need for separate ferrosilicon charges. Standard ferromanganese contains little silicon, so melt shops choose between them based on the target chemistry of the steel grade and the relative cost per unit of each element.
Imports under HTS 7202300000 may be subject to Section 232 tariffs applicable to certain steel and steel-derivative products. Importers should verify current applicability with a licensed customs broker, as coverage and exclusions can change.
