Products classified under HTS 2530.90.10.00
Greenland Cryolite Crystals
Large translucent crystals of natural cryolite mined from the Ivigtut deposit in Greenland, the world's primary source. Falls under HTS 2530.90.1000 as unprocessed natural cryolite used in metallurgical fluxes. Known for its low iron content ideal for high-purity aluminum production.
Natural Cryolite Granules
Naturally occurring granular cryolite from weathered deposits, minimally handled post-mining. Classified HTS 2530.90.1000 as it remains in natural mineral form without artificial processing. Used in granular form for certain flux applications.
Unprocessed Cryolite Flux Ore
Crude cryolite ore directly from mining operations, containing typical gangue materials, destined for aluminum flux production. HTS 2530.90.1000 covers this natural mineral in its raw, unbeneficiated state. Essential raw material for Hall-Héroult aluminum smelting process.
Natural Cryolite Ore
Raw sodium aluminum fluoride mineral extracted from deposits in Greenland, used primarily as a flux in aluminum smelting. Classified under HTS 2530.90.1000 as natural cryolite, a mineral substance not elsewhere specified. It appears as colorless to white crystalline masses or granular aggregates.
Natural Chiolite Mineral
Rare sodium aluminum chloride fluoride mineral (Na5Al3F14) occurring in cryolite deposits, used in specialty fluxes. Classified under HTS 2530.90.1000 alongside natural cryolite as nes mineral substances. Typically found as white or colorless cleavable masses.
Ivigtut Cryolite Specimen
Museum-grade natural cryolite crystals from the historic Ivigtut mine, suitable for geological collections or research. Falls under HTS 2530.90.1000 as natural cryolite, even in specimen form. Features classic cubic crystal habit and high transparency.
