Products classified under HTS 2615.90.60.30
Columbite Ore Concentrate
Columbite ore concentrate is a naturally occurring mineral primarily containing niobium (columbium) and tantalum, processed to increase niobium content for extraction. It falls under HTS 2615.90.60.30 as a niobium ore and concentrate used in metallurgical industries for producing niobium metal and alloys. The assay quantity of metal content is reported without deductions per statistical notes.
Niobite Bearing Ore Concentrate
Niobite-bearing ore concentrate consists of mineral deposits rich in niobium oxides, concentrated through gravity or magnetic separation. Classified under HTS 2615.90.60.30 for niobium (columbium) ores used directly in extraction processes. It adheres to chapter notes distinguishing unrefined ores from chemical residues.
Pyrochlore Niobium Ore Concentrate
Pyrochlore niobium ore concentrate is derived from carbonatite deposits, featuring complex niobium-tantalum-REE minerals upgraded via flotation. It is specifically under HTS 2615.90.60.30 as a niobium concentrate for ferro-niobium production in steel alloys. Statistical notes require reporting pure assay metal content.
Lueshite Columbium Ore Fines
Lueshite columbium ore fines are perovskite-structured niobium minerals ground to fine particles for hydrometallurgical processing. Classified in HTS 2615.90.60.30 as niobium concentrates, distinct from coarse iron ores per statistical definitions. Used in electronics-grade niobium oxide production.
Aeschynite Niobium Concentrate
Aeschynite niobium concentrate is a rare earth niobate mineral concentrate from granitic pegmatites, used in specialty alloy production. Falls under HTS 2615.90.60.30 for niobium ores and concentrates per the full hierarchy excluding other specified minerals. Excludes residues per chapter note restrictions.
