Products classified under HTS 2826.30.00.00
Synthetic Cryolite Powder
Synthetic cryolite, chemically sodium hexafluoroaluminate (Na3AlF6), is a white crystalline powder used primarily as a flux in aluminum smelting to lower the melting point of alumina. It falls under HTS 2826.30.00.00 as a complex fluorine salt of sodium and aluminum, distinct from natural cryolite. This industrial-grade product is supplied in bulk bags for metallurgical applications.
Industrial Grade Synthetic Cryolite
High-purity synthetic cryolite (sodium hexafluoroaluminate) in granular form for use in electrolytic aluminum production and ceramic fluxing. Classified under HTS 2826.30.00.00 due to its specific chemical composition as a fluoroaluminate complex salt. It enhances conductivity in smelting baths.
Sodium Hexafluoroaluminate Flux Grade
Flux-grade synthetic cryolite, Na3[AlF6], optimized for aluminum reduction cells with low iron impurities. This complex fluorine salt is explicitly covered by HTS 2826.30.00.00 as sodium hexafluoroaluminate. Used to dissolve alumina in Hall-Héroult processes.
