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.
