Ferrophosphorus 18-25% Phosphorus Grade
Ferrophosphorus alloy containing 18-25% phosphorus and balance iron, produced by reducing phosphate rock with carbon in electric arc furnaces. It is used primarily as a deoxidizer and alloying additive in steel production to improve fluidity and strength. Classified under HTS 7202.99.8020 as a ferroalloy other than ferrosilicon, ferrochromium, or ferromanganese.

Import Tips & Compliance
• Provide mill test certificates verifying phosphorus content (typically 18-35%) and iron balance to confirm ferrophosphorus classification
• Ensure documentation distinguishes from ferrosilicon or other ferroalloys to avoid misclassification under different subheadings
• Check for hazardous material declarations as phosphorus content may trigger DOT/IMDG shipping regulations
