Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing >50% gaseous hydrocarbons
Gaseous mixtures from gas works fall under 2705, not solid coke.
If aromatic extracts like creosote from process
Creosote and other coal tar oils separate from the coke residue.
If with high ash or clinker content
Ashy coal residues classify as Chapter 26 mineral wastes.
