More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a mixed oxide with other metals
Pure V2O5 is classified here, but if it contains other metal oxides, heading 28.25 'other' may apply.
If presented as a vanadate salt rather than an oxide
If the product is in a salt form (e.g., ammonium vanadate), heading 28.41 could apply.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the purity level is documented, as high-purity grades may be subject to different end-use considerations
• The product is chemically defined, so a certificate of analysis will support classification
• If used as a catalyst precursor, check if any environmental regulations apply
