Products classified under HTS 7202.21.75.00
Ferrosilicon 85% Grade Alloy
Ferrosilicon alloy containing 85% silicon by weight, used primarily as a deoxidizer and alloying agent in steel production to remove oxygen and improve steel quality. This product falls under HTS 7202.21.75.00 because it is a ferroalloy with silicon content between 80% and 90% by weight. It is typically supplied in lump form for metallurgical applications.
High-Silicon Ferrosilicon 82/84 Lumps
Lump-form ferrosilicon with 82-84% silicon content, essential for producing low-carbon steels and as a source of silicon in foundry applications. Classified under HTS 7202.21.75.00 due to its silicon weight percentage between 80% and 90% in an iron-silicon alloy matrix. Commonly used in electric arc furnaces for steel desoxidation.
Ferrosilicon 88% Metallurgical Grade
Metallurgical-grade ferrosilicon with 88% silicon, widely used in steelmaking for silicon addition and deoxidation, particularly in continuous casting processes. This ferroalloy is specifically covered by HTS 7202.21.75.00 for its 80-90% silicon composition by weight. It enhances steel fluidity and strength properties.
Ferrosilicon 80/82% Foundry Grade Lumps
Foundry-grade ferrosilicon lumps with 80-82% silicon content, used in iron foundries to improve cast iron quality and nodulizing treatment. Falls under HTS 7202.21.75.00 as ferrosilicon alloy within the specified silicon range. Supplied in sizes suitable for furnace charging.
