Products classified under HTS 2605.00.00.00
Cobaltite Ore
Cobaltite is a sulfosalt mineral with the chemical formula (Co,Fe)AsS, primarily mined as a source of cobalt. It falls under HTS 2605.00.00.00 as a cobalt ore due to its high cobalt content extracted through roasting and leaching processes. This ore is typically found in hydrothermal veins and processed for cobalt recovery.
Heterogenite Cobalt Ore
Heterogenite is a hydrated cobalt oxide mineral (CoO(OH)) found in oxidized zones of copper-cobalt deposits. Classified under HTS 2605.00.00.00 as a cobalt ore and concentrate due to its direct use in hydrometallurgical cobalt extraction. Commonly mined in the Democratic Republic of Congo.
Erythrite Cobalt Ore
Erythrite, or cobalt arsenate (Co3(AsO4)2·8H2O), occurs as a secondary mineral in cobalt deposits. It is imported under HTS 2605.00.00.00 as cobalt ore for its cobalt recovery potential despite arsenic content. Processed via acid leaching to separate metals.
Carrollite Cobalt Copper Ore
Carrollite (CuCo2S4) is a thiospinel mineral yielding both cobalt and copper. It qualifies under HTS 2605.00.00.00 when cobalt is the principal valuable component per assay. Mined in Central Africa for battery-grade cobalt production.
Cobalt-Bearing Laterite Ore
Laterite ores from weathered ultramafic rocks contain cobalt alongside nickel and iron oxides. Imported as HTS 2605.00.00.00 when cobalt extraction is primary, often via high-pressure acid leaching (HPAL). Sourced from Indonesia and Australia.
Glauconite Cobalt Ore
Glauconite, a mica-like clay mineral, hosts trace cobalt in sedimentary deposits. Falls under HTS 2605.00.00.00 for concentrates enriched to economic cobalt levels. Used in low-grade leaching operations.
Cobaltite-Skutterudite Mixed Ore
Mixed ore from polymetallic veins containing cobaltite and skutterudite (CoAs3). Classified HTS 2605.00.00.00 based on dominant cobalt value. Processed in smelters for multi-metal recovery.
Hydrothermal Cobalt Ore
Hydrothermal cobalt ores from high-temperature fluid deposits, rich in sulfides like linnaeite (Co3S4). HTS 2605.00.00.00 applies for raw ore shipments prior to milling. Key for electric vehicle battery supply chains.
