U.S. imports of High-Carbon Ferromanganese (Over 2% Carbon) (SITC 67141) totaled $21.0M in August 2026, imported from 9 countries.
Importers of High-Carbon Ferromanganese (Over 2% Carbon) paid $315K in duties in August 2026, an average duty rate of 1.50% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. High-Carbon Ferromanganese (Over 2% Carbon) imports of $21.0M in August 2026 ran 14% above the year-to-date monthly average of $18.4M.
Last updated: August 2026 dataHigh-carbon ferromanganese, containing more than 2% carbon by weight, is the workhorse deoxidizer and desulfurizer in carbon and alloy steel production, added during the steelmaking furnace or ladle stage to control oxygen and sulfur levels. The carbon threshold distinguishing this grade from medium- and low-carbon ferromanganese is the primary classification criterion and directly affects its metallurgical application — high-carbon grades are unsuitable where carbon pickup must be minimized. Antidumping and countervailing duty orders have historically applied to ferromanganese from certain origins, making admissibility review and scope rulings a routine part of import planning.

The 2% carbon by weight boundary is the controlling specification. Importers must provide mill certificates or chemical analysis reports confirming carbon content; a shipment misclassified between high-carbon and low-carbon grades can face reclassification and potential antidumping duty exposure if the correct grade is subject to an order. Independent laboratory testing at the port is sometimes required when documentation is disputed.
Antidumping and countervailing duty orders have been imposed on ferromanganese from specific countries at various times. Importers should check current Commerce Department and ITC order lists before contracting, and confirm whether the specific carbon grade and country of origin fall within an order's scope — scope rulings can be narrow and product-specific.
