2805.30.00.90 - Other

This HTS category, 2805.30.00.90, specifically encompasses "Other" rare-earth metals, scandium, and yttrium that are not categorized under other headings within the broader classification of alkali or alkaline-earth metals. This includes substances that, while composed of rare-earth metals, scandium, or yttrium, do not fit the more precise definitions of "intermixed" or "interalloyed" forms described in sibling categories. The inclusion of "Other" signifies a residual category for these elements when they are presented in forms not explicitly detailed elsewhere.

The primary distinction of this category lies in the form of the rare-earth metals, scandium, and yttrium. Unlike sibling categories that might differentiate based on the degree of mixing or alloying, this heading captures individual elements or compounds that do not meet those specific criteria. Therefore, classification under this code relies on the absence of significant intermixing or alloying, or the presentation of these elements in forms not otherwise specified, such as simple chemical compounds or unalloyed elemental forms that are not explicitly covered by subheadings.

As this is a leaf node, there are no further subcategories. Classification under 2805.30.00.90 is determined by whether the product consists of rare-earth metals, scandium, or yttrium, and whether it does not fit into the "intermixed or interalloyed" designations. Practical considerations for classification will often involve examining the product's composition, purity, and the presence or absence of other metals in a combined state, ensuring it does not fall under more specific or exclusionary descriptions.
