Ferric Vanadium Sulfate from Mexico
Ferric vanadium sulfate is a mixed ferric-vanadium sulfate used in water treatment as a coagulant and in vanadium battery electrolytes. It is classified under tariff item 2833.29.00 as an 'other sulfate' because it is a chemically defined inorganic sulfate of vanadium and iron, not specifically provided for elsewhere in Chapter 28.

Import Tips
• Provide the exact chemical formula and purity to the CBSA to confirm classification as a sulfate
• If the product contains both iron and vanadium, be prepared to justify why it is not a double salt of heading 28.42
• Check if the product meets the definition of a chemically defined compound under Chapter 28 Note 1
