Sodium Aluminum Fluoride (Na3AlF6, Cryolite)
Sodium aluminum fluoride (Na3AlF6, cryolite) is a complex fluoride of aluminum and sodium, essential in the Hall-Héroult process. As a fluoroaluminate, it is a complex fluorine salt, not a simple fluoride, and is classified under 2826.90 (fluoroaluminates) rather than 2826.12.00. Therefore, it is excluded from this tariff item.

Related Products under Tariff item 2826.12.00
Aluminum Fluoride (AlF3)
Aluminum fluoride (AlF3) is a white crystalline powder used primarily as a flux in aluminum smelting to lower the melting point of alumina. It is a separate chemically defined compound of aluminum and fluorine, meeting the criteria of Chapter 28 Note 1(a). It is classifiable under tariff item 2826.12.00 as a fluoride of aluminum.
Aluminum Fluoride Hydrate (AlF3·3H2O)
Aluminum fluoride hydrate (AlF3·3H2O) is a hydrated form of aluminum fluoride used as an intermediate in fluorochemical production and as a flux. As a hydrate of a chemically defined compound, it remains within Chapter 28 Note 1(b) (products dissolved in water) and is classifiable under 2826.12.00 as a fluoride of aluminum.
Aluminum Fluosilicate (Al2(SiF6)3)
Aluminum fluosilicate (Al2(SiF6)3) is a complex fluorine salt of aluminum, used as a laundry sour and in water fluoridation. Although it contains silicon, it is a fluosilicate, which falls under the subheading 'fluorosilicates, fluoroaluminates and other complex fluorine salts' (2826.90) rather than 2826.12.00, which covers only simple fluorides of aluminum. Therefore, it does not belong under this tariff item.
Potassium Aluminum Fluoride (KAlF4)
Potassium aluminum fluoride (KAlF4) is a double fluoride salt of potassium and aluminum, used as a cover flux in aluminum remelting. It is a complex fluoride, not a simple fluoride of aluminum, and is classifiable under 2826.90 (other complex fluorine salts) rather than 2826.12.00. Thus, it does not fall under this tariff item.
Synthetic Cryolite Powder (Na3[AlF6])
Synthetic cryolite powder (Na3[AlF6]) is a fine powder form of sodium hexafluoroaluminate, used in aluminum production and as an opacifier. It is a fluoroaluminate complex salt, which falls under 2826.90 (other complex fluorine salts), not under 2826.12.00 for simple aluminum fluorides. Hence, it does not belong under this tariff item.
