2827.51.00.00 - Bromides of sodium or of potassium

This HTS category, 2827.51.00.00, specifically covers bromides of sodium and potassium. These are inorganic chemical compounds where the bromide ion (Br⁻) is bonded to either a sodium (Na⁺) or potassium (K⁺) cation. Examples include sodium bromide (NaBr) and potassium bromide (KBr), which are often utilized in photography, as sedatives, or as flame retardants, depending on their purity and intended application. The classification hinges on the presence of both the bromide anion and either the sodium or potassium cation within the chemical structure.

This specific classification is distinct from its sibling category, 2827.59, which is designated for "Other" bromides and bromide oxides. While 2827.51.00.00 is precisely defined by its constituent elements (sodium or potassium with bromide), the "Other" category would encompass bromides formed with different metal cations or more complex bromide-containing inorganic compounds not otherwise specified. Therefore, the key differentiator lies in the explicit identification of sodium or potassium as the accompanying metal cation.

As this is a leaf node within the HTS, there are no further subcategories. The classification is final at this level, meaning that any product meeting the description of a sodium or potassium bromide will be entered under 2827.51.00.00. Classification at this level relies on the chemical composition and the specific identification of sodium or potassium bromides, with no further breakdown based on purity, grade, or specific end-use being provided by the HTS structure itself.
