Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically processed as a spent catalyst preparation
Prepared chemical products from catalysts may shift to 3824 if not raw residues.
If containing mainly chromium or lead instead
Same heading but different subheading based on primary metal content.
If for retail sale packaging vs industrial bulk
If packaged for consumer use rather than industrial extraction, it may be waste ash under 2621.

Import Tips & Compliance
• Submit lab assays specifying vanadium content as the primary metal to meet statistical reporting requirements
• Declare origin and process to distinguish from steel slags or waste ash
• Avoid common pitfall of undervaluation by documenting vanadium recovery value
