Importers of Ferrosilicon Manganese paid $1.2M in duties in April 2026 — an effective duty rate of 3.9% on $30.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ferrosilicon Manganese imports of $63.6M in April 2026 ran 79% above the year-to-date monthly average of $35.5M.
Last updated: April 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.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
