2826.19.90.00 - Other

This classification, "Other," within the HTS code 2826.19.90.00, pertains to inorganic fluorine salts that are not specifically enumerated under preceding subheadings within the broader category of "Fluorides." These are complex fluorine-containing chemical compounds that do not fall into the categories of ammonium fluorides or sodium fluorides. The scope is therefore broad, encompassing a variety of metallic and non-metallic fluorides.

The distinction of this category lies in its residual nature. It serves as a catch-all for fluorides that have not been classified as either ammonium fluorides (2826.19.10.00) or sodium fluorides (2826.19.20.00). Therefore, any fluoride salt not meeting the chemical composition criteria for ammonium or sodium would be examined for classification under this "Other" subheading. This necessitates a detailed analysis of the cation present in the fluoride salt.

As a leaf node in the HTS, 2826.19.90.00 does not have further subcategories. Classification decisions within this heading will depend on the specific chemical identity of the fluoride salt in question, ensuring it is not specifically covered by the sibling categories. This often involves referring to chemical nomenclature and detailed product specifications to confirm the absence of ammonium or sodium as the primary cation.
