Products classified under HTS 7202.21.50.00
Custom Blend Ferrosilicon 70-75% Mix
Custom Blend Ferrosilicon 70-75% is a plant-specific mix averaging 72.5% silicon, tailored for particular steel chemistry requirements. Classified HTS 7202.21.50.00 as 'other' within 55-80% silicon range, lacking standard grade designation. Batch certificates specify exact blend.
Ferrosilicon 65% Lumpy Form FeSi65
Ferrosilicon 65% in lumpy form contains 65% silicon by weight with iron balance, typically sized 10-100mm, used in steelmaking for silicon addition and deoxidation. Classified under HTS 7202.21.50.00 as 'other' ferrosilicon with 55-80% silicon, not fitting standard granulated or specific alloy subcategories. Its irregular lump shape suits electric arc furnace feeding.
Ferrosilicon 55.5% Borderline Grade
Ferrosilicon 55.5% Grade sits at the minimum threshold with precisely 55.5% silicon by weight, used in cost-sensitive steel alloys. Falls under HTS 7202.21.50.00 as 'other' ferrosilicon >55% up to 80% Si, distinguished from ≤55% category. Tight composition control essential.
Ferrosilicon 78% High-Silicon FeSi78
Ferrosilicon 78% High-Silicon grade approaches 80% limit with 78% Si content, used for maximum deoxidation with minimal iron dilution. HTS 7202.21.50.00 'other' category for 55-80% silicon ferrosilicon. Brittle texture requires careful handling.
Ferrosilicon 75% Grade FeSi75A
Ferrosilicon 75% Grade FeSi75A is an alloy containing approximately 75% silicon and 25% iron by weight, used primarily as a deoxidizer and alloying agent in steel production. It falls under HTS 7202.21.50.00 as ferrosilicon with silicon content between 55% and 80%, classified as 'other' since it does not meet specific subheadings for standard grades. This granular or lump form alloy is essential for controlling oxygen levels in molten steel.
High-Purity Ferrosilicon 72% FeSi72B
High-purity Ferrosilicon 72% FeSi72B has 72% silicon with low aluminum (<1%) and calcium (<0.5%), optimized for high-quality steel and stainless production. It qualifies for HTS 7202.21.50.00 as ferrosilicon containing 55-80% silicon in the 'other' category, distinguished by its impurity profile. Used in ladle metallurgy for precise alloying.
Ferrosilicon 60% Standard Grade FeSi60
Standard Ferrosilicon 60% contains 60% silicon by weight, balanced with iron and minor elements, commonly used in gray iron casting and mild steel production. Under HTS 7202.21.50.00, it is 'other' ferrosilicon with silicon between 55-80%, not specified under granulated or calcium-bearing types. Available in crushed or natural lump sizes.
Atomized Ferrosilicon 70% Powder
Atomized Ferrosilicon 70% is produced by gas atomization resulting in spherical powder with 70% silicon content, used in powder metallurgy and welding electrodes. Classified under HTS 7202.21.50.00 as 'other' ferrosilicon (55-80% Si) since it doesn't match granulated subheading specs. Particle size typically 45-150 microns.
Low-Aluminum Ferrosilicon 68% FeSi68Al
Low-Aluminum Ferrosilicon 68% contains 68% Si with Al <0.5%, designed for aluminum-sensitive steel grades like electrical steels. HTS 7202.21.50.00 covers this as 'other' 55-80% silicon ferrosilicon without special calcium or granule specs. Critical for silicon-electrical steel production.
