Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mainly straight-run naphthas
Unprocessed or minimally processed naphtha wastes remain under specific naphtha waste provisions.
If benzene content exceeds 50% by weight
Subheading notes define benzol products separately when aromatic concentration is high.
If used as petroleum coke feedstock
Residues suitable for coke production shift to petroleum coke and related materials heading.
