Vanadium Pentoxide Sulfate
Vanadium pentoxide sulfate (V2O5·SO3) is a chemically defined inorganic compound used in catalysts for oxidation reactions and in the production of vanadium metal. It falls under HTS 2833.29.30.00 as a sulfate of vanadium, specifically classified among other vanadium sulfates due to its sulfate group and vanadium content.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as vanadates rather than sulfates
Vanadates are antimony oxides or vanadates classified under heading 2825, not sulfates.
If for vanadium metal salts used as luminophores
Salts of metals used as luminophores fall under 2841 per Chapter Note exclusions, shifting from sulfates.
If impure or in mixtures exceeding chemical definition thresholds
Complex mixtures or non-chemically defined preparations go to 3824, not pure inorganic compounds of Chapter 28.

Import Tips & Compliance
• Verify chemical purity and composition via lab analysis to confirm classification as a vanadium sulfate under Chapter 28
• Include Safety Data Sheets (SDS) and Certificates of Analysis in documentation to avoid misclassification as mixtures
• Check for REACH or TSCA compliance if destined for EU or US markets, as vanadium compounds may require notifications
