2620.99.75.20 - Vanadium bearing materials

This classification covers miscellaneous slag, ash, and residues, excluding those from iron or steel production, which are characterized by the presence of arsenic, metals, or their compounds. Crucially, for goods to fall under this heading, they must not have undergone any significant advancement in value or condition through processing. Furthermore, if these residues contain more than 2 percent by weight of copper, lead, or zinc, they are specifically excluded from this category if intended for recovery of those metals.

As this is a terminal node in its branch of the tariff schedule, there are no sibling categories at this exact level to distinguish it from. Its specificity lies in the exclusion of materials advanced in value or condition, and the specific quantitative threshold for copper, lead, and zinc if recovery is intended. This ensures that materials undergoing further processing or designated for specific recovery operations are classified elsewhere.

This category serves as a residual catch-all for a variety of industrial byproducts that do not fit more specific classifications. Its subcategories further refine the classification based on the presence of specific precious metals or the absence of vanadium, silver, and gold, allowing for precise tariff determination. These include materials containing silver (2620.99.75.60), materials containing gold (2620.99.75.80), and a broad category for other materials that do not contain vanadium, silver, or gold (2620.99.75.90).
