2606.00.00.90 - Other

This HTS category, 2606.00.00.90, specifically covers "Other" aluminum ores and concentrates. This classification applies to all forms of aluminum-bearing ores and their concentrated preparations that are not otherwise specifically enumerated under preceding subheadings within Chapter 2606. This typically includes materials where aluminum is the principal element by weight, and which are intended for metallurgical processing or chemical extraction of aluminum. Examples might include less common aluminum minerals or beneficiated ores that don't fit into more defined categories.

It is crucial to distinguish this "Other" category from its sibling, 2606.00.00.10, which is dedicated to calcined bauxite. Calcined bauxite is bauxite that has undergone a heating process to remove water and impurities, altering its physical and chemical properties for specific industrial uses. Therefore, goods classified under 2606.00.00.90 will not have undergone such calcination and represent the raw or concentrated forms of aluminum ores not meeting the specific criteria for calcined bauxite.

As this is a leaf node, there are no further subcategories within 2606.00.00.90. Classification into this subheading relies on the absence of specific characteristics that would place the material into a more precisely defined category. Customs professionals will therefore need to consider the mineralogical composition and processing status of the aluminum-bearing material to ensure accurate classification within this residual category.
