2836.99.10.00 - Cobalt carbonates

This HTS classification, 2836.99.10.00, specifically covers cobalt carbonates. These are inorganic chemical compounds where cobalt is combined with the carbonate radical. Examples of products falling under this heading include various forms of cobalt carbonate, such as basic cobalt carbonate, which are typically used as pigments, catalysts, or in the production of other cobalt compounds.

Within the broader category of "Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate," this subheading distinguishes itself by its specific focus on cobalt. It is differentiated from its siblings, such as bismuth carbonate (2836.99.20.00), commercial ammonium carbonate (2836.99.30.00), and lead carbonates (2836.99.40.00), by the distinct chemical identity and properties of cobalt as the primary metal constituent of the carbonate compound.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, the classification of a product under 2836.99.10.00 relies solely on its identification as a cobalt carbonate. Importers and exporters should ensure that the chemical composition definitively identifies the product as a cobalt carbonate to meet the requirements of this specific tariff line.
