2826.30.00.00 - Sodium hexafluoroaluminate (Synthetic cryolite)

This HTS category, 2826.30.00.00, specifically classifies sodium hexafluoroaluminate, commonly known as synthetic cryolite. This compound is a white crystalline solid that is primarily used as a flux in the electrolytic production of aluminum. Its specific chemical composition and application in this industrial process are key to its distinct classification.

Within the broader heading of "Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts" (2826), this sub-heading is distinguished from its siblings. The sibling category, 2826.90, covers "Other" complex fluorine salts that do not fit the specific definitions of fluorides, fluorosilicates, or the fluoroaluminates defined here. Therefore, this classification is for a precisely defined chemical compound with a particular industrial use, not for a broader range of complex fluorine salts.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 2826.30.00.00 is definitive for goods that meet the description of sodium hexafluoroaluminate. Importers and exporters should confirm that the product's chemical composition and intended use align with the established definition of synthetic cryolite to ensure accurate declaration and compliance.
