Products classified under Tariff item 2617.10.00
Antimony Concentrate from Bolivian Mines
High-grade antimony concentrate produced from Bolivian stibnite deposits, with antimony content typically 50-60% after flotation processing. This concentrate remains in an unrefined mineral state, not yet subjected to smelting or other metallurgical processes, and is therefore classified as an antimony ore concentrate under tariff item 2617.10.00.
Antimony-Gold Bearing Concentrate
Flotation concentrate from deposits containing both antimony and byproduct gold, with antimony as the primary metal value. Since antimony is the chief value and the product is an ore concentrate, it falls under tariff item 2617.10.00, not under precious metal ores.
High-Grade Chinese Antimony Concentrate
Premium antimony concentrate exceeding 60% antimony content, produced from Chinese stibnite mines via flotation. This unrefined concentrate is used globally as feedstock for antimony metal and trioxide production, and qualifies under tariff item 2617.10.00 as an antimony ore concentrate.
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. When antimony is the chief value, this ore qualifies under tariff item 2617.10.00, distinct from lead ores.
Kermesite Antimony Oxide Ore
Kermesite (Sb2S2O) is a rare antimony ore mineral formed through oxidation of stibnite, containing antimony in both oxide and sulfide forms. As a natural antimony ore suitable for metallurgical extraction, it falls under tariff item 2617.10.00.
Stibnite Ore
Stibnite is the primary mineral ore of antimony, consisting mainly of antimony trisulfide (Sb2S3), typically appearing as steel-gray crystals. Mined directly from natural deposits, it falls under tariff item 2617.10.00 as an antimony ore.
Tetrahedrite Antimony-Copper Ore Concentrate
Tetrahedrite ((Cu,Fe)12Sb4S13) ore concentrate where antimony contributes significant value alongside copper, processed via selective flotation. When antimony is the chief value, this concentrate is classified under tariff item 2617.10.00, not under copper ores.
