2846.10.00.10 - Cerium oxides

This HTS category, 2846.10.00.10, specifically covers cerium oxides. Cerium oxides are inorganic chemical compounds containing the element cerium in an oxidized state. They are typically encountered as powders or solid materials and are utilized in a variety of industrial applications, including polishing compounds for glass and lenses, catalysts, and as components in specialized ceramics and pigments.

At this level of classification, 2846.10.00.10 is distinguished from its sibling category, 2846.10.00.50, which encompasses "Other" cerium compounds. While this category is exclusively for cerium oxides, the sibling category would include other cerium compounds that are not oxides, such as cerium salts or hydroxides. Therefore, the key differentiator is the specific chemical form – the presence of oxygen bonded to cerium.

As this node is a leaf node in the HTS structure, there are no further subcategories. Classification within this heading is solely determined by whether the product is definitively identified as a cerium oxide. This ensures precise categorization of cerium-based inorganic chemicals, focusing on a specific and industrially significant compound within the broader group of cerium compounds.
