Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tin-dominant from alloy scrap
Tin residues classify under Chapter 80 for other base metals.
If not used for metal extraction
Fails chapter note (a)/(b); becomes general waste ash.
If other non-zinc metal furnace residues
Furnace slag for lead/copper primarily under 2617.
