Subheadings
Products classified under HTS 2615.90.60
Zirconium Zircon Sand Concentrate
Zircon sand is a natural concentrate of zirconium silicate (ZrSiO4) extracted from mineral deposits, primarily used in ceramics and refractories. It falls under HTS 2615.90.60 as 'other' ores and concentrates of zirconium, not specified elsewhere in the subheading. The assay quantity of zirconium oxide content is reported without deductions per statistical notes.
Vanadium Pentoxide Ore Concentrate
Vanadium ore concentrate containing vanadium pentoxide (V2O5), derived from magnetite or titanomagnetite deposits, used in steel alloying. Classified under HTS 2615.90.60 as 'other' vanadium ores and concentrates not covered by specific subheadings. Meets chapter requirements for metallurgical extraction.
Tantalum Columbite Ore Concentrate
Columbite-tantalite (coltan) concentrate rich in tantalum niobates, sourced from pegmatite deposits in Africa and Australia. Falls under HTS 2615.90.60 as 'other' niobium/tantalum ores not specified elsewhere. Used for tantalum capacitor production in electronics.
Niobium Pyrochlore Concentrate
Pyrochlore ore concentrate containing niobium oxide (Nb2O5), primarily from carbonatite deposits like Araxá, Brazil. Classified in HTS 2615.90.60 as other niobium ores and concentrates for stainless steel and superalloy production.
Zirconium Baddeleyite Ore Concentrate
Baddeleyite concentrate, a monoclinic zirconia (ZrO2) ore from alkaline intrusions, used in high-purity zirconia production. HTS 2615.90.60 covers this as other zirconium ores, with statistical reporting of ZrO2 assay content.
