Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mainly lead
Lead-dominant slags use 2620.20, based on primary metal per subheading structure.
If gold content recovered into waste/scrap form
Processed precious metal waste classifies under Chapter 71, not industrial residues.
If from iron or steel manufacturing
Ferrous slags excluded from 2620 by hierarchy, directed to Chapter 72.

Import Tips & Compliance
• Label shipments with precise gold assay to match statistical reporting
• Confirm no arsenic extraction intent if declaring under 2620(b) to avoid scrutiny
• Partner with certified processors for end-use verification
