2615.90.60.90 - Vanadium ores and concentrates

This classification, HTS 2615.90.60.90, specifically covers vanadium ores and concentrates that are not elsewhere specified within heading 2615. Vanadium ores are naturally occurring geological materials from which vanadium can be economically extracted. Concentrates, in this context, are materials that have undergone a process of beneficiation to increase the vanadium content and remove waste material, preparing them for smelting or further refining.

It is crucial to distinguish this category from its siblings, HTS 2615.90.60.30 (Niobium (columbium) ores and concentrates) and HTS 2615.90.60.60 (Tantalum ores and concentrates). While all fall under the broader heading of "Niobium (columbium), tantalum, vanadium or zirconium ores and concentrates," this specific subcategory is exclusively for those where vanadium is the primary valuable metal, or where the ore/concentrate is not predominantly composed of niobium, tantalum, or zirconium. The determination will rely on the principal metal content as defined by relevant industry standards or customs regulations.

As this is a leaf node within the Harmonized Tariff Schedule, there are no further subcategories. Therefore, classification into HTS 2615.90.60.90 is definitive for vanadium ores and concentrates that do not fit into the more specific niobium or tantalum classifications at the same level. Practical classification will often involve analyzing assay reports to confirm the predominant metal content and ensuring the material is indeed an ore or a concentrated form thereof.
