Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfur extracted as primary product
Sulfur from roasted pyrites becomes 2503 commodity post-processing.
If pig iron production ready
Advanced processing into pig iron shifts to Chapter 72.

Import Tips & Compliance
• Assay reports must show no metal extraction; label sulfur percentage accurately
• Common issue: retest at port if humidity affects content

Roasted Iron Pyrite Concentrate
Roasted iron pyrites, also known as pyrite ash, are thermally processed iron sulfide ores used primarily as a source of sulfur and iron in industrial applications. This product falls under HTS 2601.20.00.00 as roasted iron pyrites, distinct from unroasted ores in 2601.11 or 2601.12. It is commonly roasted to remove volatile sulfur content for easier handling and extraction.
Pyrite Ash from Roasting
Pyrite ash is the residue obtained from roasting iron pyrites to produce sulfuric acid, containing residual iron oxides and sulfur. Classified under HTS 2601.20.00.00 specifically for roasted iron pyrites before further chemical processing. It serves as a raw material in iron production and fertilizer manufacturing.
Calcined Iron Pyrite Lumps
Calcined or roasted iron pyrite lumps are heat-treated chunks of FeS2 ore, reducing sulfur volatility for safe transport and use in metallurgy. This HTS 2601.20.00.00 covers roasted forms explicitly, separating from raw pyrites. Primarily imported for sulfuric acid plants and iron smelters.
Roasted Pyritic Ore Fines
Fines from roasted pyritic iron ore, processed to stabilize for industrial sulfur recovery and iron concentrate production. Falls under HTS 2601.20.00.00 as roasted iron pyrites, not distinguished by size like unroasted ores. Used in cement and chemical industries.
Industrial Roasted Pyrite Pellets
Pelletized roasted iron pyrites for uniform feeding into roasters and smelters, heat-treated for density. Classified in HTS 2601.20.00.00 despite pellet form, as roasting defines it over agglomeration. Used in non-ferrous metal recovery.
