U.S. imports of Low- & Medium-Carbon Ferromanganese (Not Over 2% Carbon) (SITC 67149) totaled $12.5M in August 2026, imported from 10 countries.
Importers of Low- & Medium-Carbon Ferromanganese (Not Over 2% Carbon) paid $245K in duties in August 2026, an average duty rate of 1.96% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataRefined ferromanganese with no more than 2% carbon commands a significant price premium over the high-carbon grade because its low carbon content makes it suitable for stainless steel, specialty alloy, and high-strength low-alloy (HSLA) steel applications where carbon pickup is tightly controlled. The refining process — typically oxygen blowing or electrolytic production — is more energy-intensive, concentrating production in regions with competitive power costs. Buyers should verify that supplier certifications clearly document carbon content at or below the 2% threshold, as misclassification between this heading and high-carbon ferromanganese (67141) carries antidumping duty implications.

Low- and medium-carbon ferromanganese is preferred in stainless steel, electrical steel, and HSLA grades where the carbon specification of the finished product is tight. Adding high-carbon ferromanganese in these heats would require additional decarburization steps, increasing cost and processing time, so the refined grade is specified from the outset.
A mill certificate or ladle analysis report from the producing facility, showing carbon content at or below 2% by weight, is the primary supporting document. For high-value or high-volume shipments, importers often commission independent third-party laboratory analysis to corroborate the producer's certificate, particularly when the declared carbon level is close to the 2% threshold.
