This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically for zinc extraction
Narrower subheading 2620.19.30 applies if explicitly designated for zinc recovery processes.
If refined copper-zinc scrap
If sorted as usable copper-zinc scrap rather than residue, it moves to Chapter 74.
If other waste incineration residues
Non-metal extraction residues from incineration classify under 2621.

Import Tips & Compliance
• Submit lab assays showing zinc as majority component to justify 'mainly zinc' criteria
• Avoid common pitfall of incomplete hazardous material declarations for arsenic
• Document end-use for chemical manufacture or extraction to meet heading 2620 note
