Ferrosilicon 93% Lumps for Steel Deoxidation from China

Lump-form ferrosilicon with 93% silicon by weight, essential for deoxidizing steel melts and preventing porosity in castings. This ferroalloy is specifically classified in HTS 7202.21.90.00 for its high silicon concentration in an iron-silicon matrix. It promotes dense, high-quality steel structures in foundries.

Import Tips

Certify silicon percentage via independent lab analysis at entry to match HTS 7202.21.90.00 high-silicon criteria precisely

Document end-use as steelmaking additive to support classification and avoid chemical chapter shifts

Avoid bulk unpackaged shipments; use sealed bags to minimize oxidation issues disallowed for duty relief
