Calcium Silicon 30/65 Ferroalloy from Canada
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.

Import Tips
• Provide mill test certificates verifying calcium (28-32%) and silicon (62-68%) content to confirm classification under 7202.99.20.00
• Ensure proper hazardous material documentation as calcium silicon can react with moisture; common pitfall is inadequate UN packaging certification
• Declare exact alloy composition on entry to avoid reclassification to general ferroalloys under 7202.99.80
