Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If still functional as catalyst
Active metal catalysts (vanadium compounds) are in Chapter 28, not residues.
If advanced in value or condition
Subheading excludes processed residues, placing them in later 2620.99 categories.
If carbon-based spent catalyst
Certain carbon electrode residues with vanadium may go to Chapter 85.
