Raw Iron Pyrite Lumps
Raw iron pyrite lumps are unroasted iron pyrites in their natural lump form, composed mainly of FeS2. They are extracted directly from mines and have not been subjected to roasting, calcination, or mixing. These lumps are used as a source of sulfur and iron in industrial processes, and they qualify under tariff item 2502.00.00 as unroasted iron pyrites.

Bulk Unroasted Pyrite Sand
Bulk unroasted pyrite sand consists of naturally occurring iron pyrite (FeS2) grains sourced from sedimentary deposits. It remains in a crude, unroasted state, having only been subjected to physical processes such as washing or screening, which are permitted under Chapter 25 Note 1. This product is used in water treatment and as an abrasive, and it qualifies under tariff item 2502.00.00 as unroasted iron pyrites.
Marcasite Iron Pyrite Crystals
Marcasite iron pyrite crystals are a natural variety of unroasted iron pyrites (FeS2) in crystalline form. They are not roasted or calcined, and their physical form does not affect classification under Chapter 25. These crystals serve as a source of sulfur in industrial applications and as collector specimens, both falling under tariff item 2502.00.00.
Pyrrhotite-Unroasted Pyrite Blend
This natural mineral blend contains unroasted iron pyrites along with pyrrhotite, a related iron sulfide mineral, mined together as a sulfur-bearing ore. The principal component is iron pyrite, and the product is not roasted or processed beyond crushing or grinding. It is used in steel desulfurization and falls under tariff item 2502.00.00 as unroasted iron pyrites.
Unroasted Pyrite Ore Fines
Unroasted pyrite ore fines are fine-grained iron pyrites ground to less than 10mm particle size during extraction. The product is not thermally processed, and the grinding is a mechanical process permitted under Chapter 25 Note 1.
