Stibnite Ore
Stibnite is the primary mineral ore of antimony, consisting mainly of antimony trisulfide (Sb2S3), typically appearing as steel-gray crystals. It falls under HTS 2617.10.00.00 as a natural antimony ore mined directly from deposits and processed into concentrates for metal extraction. This classification covers unrefined antimony-bearing materials used in industrial smelting.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing significant lead alongside antimony
Ores with lead as the principal metal fall under lead ores in heading 2607, based on dominant metal value.
If processed as industrial slag or residue
Slag, ash, or residues used for metal extraction classify under heading 2620 per chapter notes.
If refined into unwrought antimony metal
Unwrought antimony metal shifts from ores (Chapter 26) to refined forms in Chapter 81.

Import Tips & Compliance
• Obtain assay certificates verifying antimony content to meet statistical reporting requirements without deductions
• Declare exact metal content per US Customs guidelines to avoid penalties for misclassification
• Check for export restrictions from source countries, as antimony ores are often subject to quotas

Antimony Concentrate from Bolivian Mines
High-grade antimony concentrate produced from Bolivian stibnite deposits, with antimony content typically 50-60% after flotation processing. Classified under HTS 2617.10.00.00 as it remains an ore concentrate, not yet smelted into metal. Used primarily for antimony trioxide production in flame retardants.
Jamesonite Antimony-Lead Ore
Jamesonite (Pb4FeSb6S14) is a sulfosalt mineral ore containing both antimony and lead, mined as a primary antimony source in some deposits. It qualifies for HTS 2617.10.00.00 when antimony is the chief value, distinguishing it from pure lead ores. Concentrates are roasted to recover antimony for alloys and compounds.
Kermesite Antimony Oxide Ore
Kermesite (Sb2S2O) is a rare antimony ore mineral formed through oxidation of stibnite, containing antimony in oxide-sulfide form. It is classified under HTS 2617.10.00.00 as an antimony ore and concentrate suitable for industrial extraction. Primarily sourced from secondary deposits for chemical manufacturing.
Antimony-Gold Bearing Concentrate
Flotation concentrate from deposits containing both antimony and byproduct gold, with antimony as the primary metal value. Falls under HTS 2617.10.00.00 for antimony ores, separated from precious metal ores by chief value determination. Used in refractory gold processing and antimony recovery.
