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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not thermally roasted and particles exceed 4.75 mm
Unroasted coarse iron ores including non-roasted pyrites fall under 2601.11.0060 per statistical note definition.
If used industrially for metal extraction post-roasting
Roasted pyrites processed as slag/residues for metal recovery shift to Chapter 26 heading 2620 per chapter notes.
If primarily valued as sulfur source after extensive processing
If roasting extracts sulfur as main product, it may classify as sulfur under 2503 rather than ore.

Import Tips & Compliance
• Verify roasting certification and sulfur content via assay reports to confirm classification under 2601.20; ensure no metal extractions have occurred to avoid reclassification as residues
• Common pitfall: mislabeling as unroasted ore leads to incorrect duties; provide lab analysis for customs
Related Products under HTS 2601.20.00.00
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.
Sulfur-Bearing Roasted Pyrite
Roasted pyrite retaining significant sulfur content for direct use in acid production, thermally treated to remove impurities. HTS 2601.20.00.00 applies to this pre-extraction roasted form of iron pyrites. Common in fertilizer and steel sectors.
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.
