Sodium Vanadate Na3VO4
Sodium vanadate (Na3VO4) is a white or yellowish powder used in protein phosphorylation studies and as a corrosion inhibitor. Its tetrahedral vanadate ion and hydroxide-like structure place it under tariff item 2825.30.00 as a vanadium hydroxide derivative, despite the sodium content.

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 classified as a salt of an oxometallic acid
Sodium vanadate may be viewed as a sodium salt of vanadic acid, which falls under heading 28.41 rather than 28.25.
If the vanadium content is not predominant
If the product is a mixed oxide with other metals, it may be classified under other inorganic bases in heading 28.25.
