2826.19 - Other:

This HTS category, 2826.19, encompasses fluorides other than those specifically classified under more detailed subheadings. It serves as a residual category for various metallic or non-metallic fluorides that do not fall into designated groups. The primary characteristic for inclusion here is the presence of the fluoride anion (F⁻) combined with another element or radical, falling within the broader classification of inorganic chemicals.

Distinguishing this category from its sibling, 2826.12.00.00, is crucial. While 2826.12.00.00 is exclusively for aluminum fluorides, category 2826.19 is reserved for all other types of fluorides. This means if a fluoride is not an aluminum fluoride, it will likely be found within this broader 2826.19 classification, pending further subheading differentiation.

The subcategories within 2826.19 provide for further refinement based on the cation or associated radical. These include specific classifications for ammonium fluorides (2826.19.10.00) and sodium fluorides (2826.19.20.00). The remaining subdivisions, such as "Other" (2826.19.90.00), are intended for all other fluorides not falling under the more specific ammonium or sodium subheadings, ensuring comprehensive coverage of diverse fluoride compounds.
