Ferrosilicon 93% Lumps for Steel Deoxidation from Mexico
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
