Subheadings
Products classified under Tariff item 26.05
Carrollite Cobalt Copper Ore
Carrollite is a thiospinel mineral (CuCo2S4) that yields both cobalt and copper. It falls under this tariff item when cobalt is the principal valuable component as determined by assay, making it a cobalt ore rather than a copper ore.
2605.00.00Cobalt-Bearing Laterite Ore
Cobalt-bearing laterite ores from weathered ultramafic rocks contain cobalt alongside nickel and iron oxides. They are classified under this tariff item when cobalt extraction is the primary purpose, often processed via high-pressure acid leaching.
2605.00.00Cobaltite Ore
Cobaltite is a sulfosalt mineral with the formula (Co,Fe)AsS, mined primarily as a source of cobalt. It falls under this tariff item due to its high cobalt content, extracted through roasting and smelting processes.
2605.00.00Cobaltite-Skutterudite Mixed Ore
This mixed ore from polymetallic veins contains cobaltite and skutterudite (CoAs3). It is classified under this tariff item based on dominant cobalt value, and is processed in smelters for multi-metal recovery.
2605.00.00Erythrite Cobalt Ore
Erythrite, or cobalt arsenate (Co3(AsO4)2·8H2O), is a secondary mineral found in cobalt deposits. It is imported under this tariff item for its cobalt recovery potential despite its arsenic content.
2605.00.00Heterogenite Cobalt Ore
Heterogenite is a hydrated cobalt oxide mineral (CoO(OH)) found in oxidized zones of copper-cobalt deposits. It is classified under this tariff item as a cobalt ore and concentrate due to its direct use in hydrometallurgical extraction.
2605.00.00Hydrothermal Cobalt Ore
Hydrothermal cobalt ores from high-temperature fluid deposits are rich in sulfides like linnaeite (Co3S4). This tariff item applies to raw ore shipments prior to milling, making it relevant for electric vehicle battery supply chains.
