Products classified under HTS 7202.99.80.20
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.
High-Phosphorus Ferrophosphorus 25-32% P
Ferrophosphorus with 25-32% phosphorus content, an iron-phosphorus master alloy essential for phosphorous alloy steel production. It enhances machinability in carbon steels and acts as a deoxidizer during melting. Falls under HTS 7202.99.8020 as specified ferrophosphorus ferroalloy.
Ferrophosphorus Lumps 20% Phosphorus
Lump-form ferrophosphorus with approximately 20% phosphorus, sized 10-50mm, used in electric arc furnaces for steel dephosphorization and alloying. This ferroalloy meets the Chapter 72 definition for ferrophosphorus under HTS 7202.99.8020.
Ferrophosphorus Powder 22% P Fine Grade
Atomized or crushed ferrophosphorus powder with 22% phosphorus content, particle size <1mm, used for precise alloy additions in continuous casting steel. Classified as ferrophosphorus under HTS 7202.99.8020 despite powder form, as primary form isn't specified.
Ferrophosphorus for Ductile Iron Production
Special ferrophosphorus grade optimized for ductile iron with controlled 19-21% phosphorus to promote spheroidal graphite formation. Supplied in crushed form for foundry ladle additions. Properly classified under ferrophosphorus HTS 7202.99.8020.
Atomized Ferrophosphorus 20-25% P
Atomized ferrophosphorus particles 20-25% P, spherical morphology for uniform melting in specialty steel production. Used in high-speed tool steels and wear-resistant castings. HTS 7202.99.8020 classification unchanged by atomization process.
Standard Ferrophosphorus FeP18-22 Grade
Standard grade ferrophosphorus alloy (FeP18-22) with 18-22% P, produced from electric furnace smelting of iron ore and phosphate. Primary use in gray iron and steel for improved castability and machinability. HTS 7202.99.8020 specifically covers ferrophosphorus.
