Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other phosphorus oxides predominate over vanadium
Mixtures where phosphorus oxides are principal classify under inorganic acids/oxides of phosphorus.
If containing arsenic, lead, or mercury compounds
Toxic metal mixtures have specific subheadings within 3824.99.39.
If rare-earth modified vanadium salts
Salts of metals not elsewhere specified including vanadium modifications go to Chapter 28 heading 2841.
