Industrial Calcium Silicon 30/60 Briquettes
Calcium silicon 30/60 formed into briquettes (50x50mm) for easier handling and reduced dust in steel plants. This physical form of the ferroalloy is still classified under HTS 7202.99.20.00 as calcium silicon, not further worked beyond simple compaction.

Import Tips & Compliance
• Briquettes remain classified as ferroalloy if no binders used; document pure compaction process
• Weight per briquette and binding method must be declared

Calcium Silicon 30/65 Ferroalloy
Calcium silicon 30/65 is a ferroalloy containing approximately 30% calcium and 65% silicon, used primarily as a deoxidizer and desulfurizer in steel production. It falls under HTS 7202.99.20.00 as a specific type of calcium silicon ferroalloy not elsewhere specified in heading 7202. This master alloy helps control non-metallic inclusions in molten steel.
Calcium Silicon 24/70 Deoxidizer Lump
This ferroalloy grade with 24% calcium and 70% silicon is supplied in lump form (10-50mm) for use in secondary steel refining. Classified under HTS 7202.99.20.00 as calcium silicon, it provides both deoxidation and desulfurization functions in ladle metallurgy.
Calcium Silicon Cored Wire Filler
