2846.90.20.84 - Other

This HTS category, 2846.90.20.84, specifically covers mixtures of rare-earth oxides or rare-earth chlorides that are not specifically enumerated under other subheadings within the 2846.90 classification. It encompasses compounds where rare-earth metals are present, and the mixture is not predominantly yttrium or scandium based, nor is it solely cerium chlorides. The focus is on the combined presence of various rare-earth metal oxides or chlorides in a blended form.

This subheading is distinct from sibling category 2846.90.20.82, which is reserved for mixtures where yttrium or scandium are the predominant rare-earth metals. Therefore, this category applies when the mixture contains a broader range of rare-earth elements or when the predominance of yttrium or scandium is absent. It serves as a residual category for rare-earth oxide and chloride mixtures that do not fit into more specific classifications.

As this is a leaf node within the HTS structure, there are no further subdivisions under 2846.90.20.84. Classification into this category relies on the absence of specific rare-earth metal predominance (like yttrium or scandium) and the material being a mixture of rare-earth oxides or chlorides, not specifically cerium chlorides or other more precisely defined categories. Practical considerations for classification would include laboratory analysis of the composition to confirm the presence of multiple rare-earth elements and the absence of a single predominant metal.
