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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If granulated for granulation process
Granulated slag from metal recovery differs from natural ores.
If smelted into waste and scrap antimony
Processed antimony waste/scrap moves to Chapter 81.
If mineral earths with antimony traces
Earths and mineral substances not primarily ores fall under 2530.

Import Tips & Compliance
• Submit XRF or ICP assay results for precise antimony quantification
• Verify no municipal waste incineration origin per Chapter 26 exclusions
• Prepare for potential BIS export control checks on high-purity concentrates

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.
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.
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.
High-Grade Chinese Antimony Concentrate
Premium antimony concentrate (>60% Sb) exported from major Chinese producers like Hunan province mines via flotation of stibnite. HTS 2617.10.00.00 applies to this unrefined form used globally for antimony metal and trioxide production. Subject to frequent trade quotas affecting import volumes.
Tetrahedrite Antimony-Copper Ore Concentrate
Tetrahedrite ((Cu,Fe)12Sb4S13) ore concentrate where antimony contributes significant value alongside copper, processed via selective flotation. Classified HTS 2617.10.00.00 when antimony chief value prevails over copper. Common in polymetallic deposits for alloy and chemical applications.
