2834.29.05.00 - Of bismuth

This HTS category, 2834.29.05.00, specifically classifies **nitrates of bismuth**. These are inorganic chemical compounds containing the nitrate radical (NO₃) combined with bismuth. Examples of such compounds would include bismuth nitrate pentahydrate, commonly used in pharmaceuticals and cosmetics for its astringent and antiseptic properties. The classification rests on the chemical composition, identifying bismuth as the defining metal cation in the nitrate salt.

When distinguishing this category from its siblings, the key differentiator is the specific metal. While all share the nitrate classification and fall under "Other" nitrates, 2834.29.10.00 covers nitrates of calcium, 2834.29.20.00 covers nitrates of strontium, and 2834.29.51.00 is a residual category for other metal nitrates not specifically enumerated. Therefore, any nitrate compound where the metallic element is solely bismuth will find its correct classification here.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is definitive based on the presence of bismuth within the nitrate compound. Importers and exporters should ensure that the chemical identity of their product precisely matches bismuth nitrate to utilize this specific HTS code.
