Products classified under HTS 7202.93.80.00
Standard Ferroniobium Lumps 60-70% Nb
Irregular lumps of ferroniobium alloy with 60-70% niobium content, ideal for electric arc furnace steelmaking additions. Classified under HTS 7202.93.80.00 as general ferroniobium not meeting specialized grade criteria. Packaged in 50kg steel drums for industrial use.
Ferroniobium 68% Nb Low Carbon Grade
Low-carbon ferroniobium alloy at 68% niobium, designed for applications requiring minimal carbon pickup in stainless steel production. Classified as 'other' under HTS 7202.93.80.00 due to standard specifications. Delivered in 100kg supersacks.
Master Ferroniobium Alloy 62% Nb
Master alloy ferroniobium with 62% niobium optimized for micro-alloying in continuous casting steel. HTS 7202.93.80.00 covers this as other ferroniobium not in specific grades. Low aluminum and titanium impurities.
Ferroniobium Chips 64% Nb Recycling Grade
Clean ferroniobium chips from processing with 64% niobium recovery grade for remelting. Under HTS 7202.93.80.00 as other ferroniobium scrap not fitting waste categories. Sized under 25mm.
Premium Ferroniobium 67% Nb Pipeline Steel
High-spec ferroniobium 67% Nb for API pipeline steel with tight control on trace elements. HTS 7202.93.80.00 for general ferroniobium import. Bulk density optimized for feeder use.
Ferroniobium Powder 65% Nb Atomized
Gas atomized ferroniobium powder 65% Nb for powder metallurgy applications. Classified HTS 7202.93.80.00 as other ferroniobium despite powder form. Mesh size -100.
Ferroniobium Briquettes 63% Nb
Pressed briquettes of ferroniobium 63% Nb for consistent dosing in steel ladles. HTS 7202.93.80.00 covers this formed ferroalloy. Density >4.5 g/cm³.
Ferroniobium 65% Niobium Grade A
A ferroalloy containing approximately 65% niobium and 35% iron, used primarily in the production of high-strength low-alloy steels for construction and automotive applications. This product falls under HTS 7202.93.80.00 as 'other' ferroniobium, not qualifying for specific higher-grade exemptions. It is supplied in lump form with standard purity levels.
Industrial Ferroniobium 66% Nb Vacuum Melted
Vacuum induction melted ferroniobium with 66% niobium, low impurity levels for specialty steel production like pipeline grades. This 'other' ferroniobium under HTS 7202.93.80.00 distinguishes it from basic grades. Supplied as crushed material sized 10-50mm.
Ferroniobium Granules 65% Nb for Steel Inoculation
Granulated ferroniobium with 65% niobium content, optimized for uniform dispersion in ladle metallurgy. Falls under HTS 7202.93.80.00 as other ferroniobium ferroalloys. Particle size 3-10mm for foundry addition.
