Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If partially beneficiated
Any advancement in value/condition moves out of the 'not advanced' subheading.
If pure vanadium oxide
Refined vanadium compounds are chemicals in Chapter 28, not residues.
If primarily petroleum residue
Bulk petroleum coke/residues with incidental vanadium may classify in Chapter 27.
