Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If gold is the chief value metal
Precious metal ores dominate classification under 2616 regardless of antimony presence.
If gold extracted and unworked
Refined gold bullion classifies as precious metal, not ore.
If from leaching residues
Solution residues for metal recovery per heading 2620 notes.

Import Tips & Compliance
• Perform chief value calculation including gold content to justify 2617 classification
• Segregate precious metal recovery documentation from antimony declarations
• Ensure concentrates meet 'coarse' particle size if applicable for statistical notes

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.
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.
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.
