Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If calcined to nickel oxide
Heat-treated to oxide form becomes Chapter 28 metal oxide, not residue.
If from precious metal refining
If co-produced with PGMs, classified as precious metal residues.
