U.S. imports of Ferrosilicon Containing 55% or Less Silicon (HS 720229) totaled $4.5M in August 2026, imported from 13 countries.
Importers of Ferrosilicon Containing 55% or Less Silicon paid $69K in duties in August 2026, an average duty rate of 1.51% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataLow-silicon ferrosilicon — containing 55% or less silicon by weight — serves as a deoxidizer and alloying agent in steelmaking and foundry operations, with magnesium content driving the split between 7202290010 (over 2% magnesium) and 7202290050 (2% or less magnesium). Canada is the leading US supplier, followed by Thailand, India, Brazil, and Mexico. Ferrosilicon has historically been subject to antidumping duty orders from multiple countries, so importers should verify current order scope and applicable cash deposit rates before contracting supply.

The US schedule subdivides 7202.29 based on whether magnesium content exceeds 2% by weight. Ferrosilicon with over 2% magnesium (7202290010) is used in specific nodularizing applications in ductile iron production, while the lower-magnesium grade (7202290050) covers the broader deoxidizer and alloying market. Accurate chemical analysis certificates are essential to support the correct subheading declaration.
The US has maintained antidumping duty orders on ferrosilicon from several countries over the years. Importers should check the current scope of active orders with the Department of Commerce and confirm whether their supplier's country of origin and product specifications fall within an order's scope before finalizing purchase agreements, as retroactive duty liability can be significant.
