2837.11.00.00 - Of sodium 🖩

This HTS category, 2837.11.00.00, specifically covers inorganic cyanides and cyanide oxides where the primary cation is sodium. This includes well-known compounds such as sodium cyanide (NaCN) and sodium cyanate (NaOCN). These substances are characterized by the presence of the cyanide radical (CN⁻) or the cyanate radical (OCN⁻) bonded to sodium. Their applications are diverse, ranging from mining and metallurgy (e.g., gold extraction) to electroplating, chemical synthesis, and the production of dyes and pharmaceuticals.

This classification is distinct from its sibling category, 2837.19.01, which encompasses all other inorganic cyanides, cyanide oxides, and complex cyanides not of sodium. Therefore, if a cyanide compound contains a cation other than sodium, or if it is a complex cyanide involving sodium along with other metals, it would fall under the "Other" category (2837.19.01). The defining characteristic for inclusion here is the exclusive or primary presence of sodium as the associated metal.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under 2837.11.00.00 is final once the material is identified as a sodium-based inorganic cyanide or cyanide oxide. Importers and exporters should ensure that the chemical composition and origin documents clearly confirm the sodium content and the presence of the cyanide or cyanate radical to facilitate accurate customs declaration.
