Arsenic-Bearing Copper Smelter Residue
Residue generated from copper smelting processes containing arsenic and metal compounds, used in industry for metal extraction or chemical compound production. It falls under HTS 2620.99.75 as unprocessed slag-like material not advanced in value, with low copper content under 2% to avoid recovery treatment classification.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from municipal waste incineration
Municipal waste ash/residues are specifically excluded from 2620 and classified under 2621.
If roasted copper-bearing residues advanced in value
If chemically treated or roasted for metal recovery, it shifts to Chapter 26 roasted residues.
If from iron or steel manufacture
Ferrous slag/ash residues are reclassified under Chapter 72, excluding them from 2620.

Import Tips & Compliance
• Verify metal content via assay reports to confirm under 2% Cu, Pb, Zn thresholds per statistical notes
• Provide documentation proving residue is from non-iron/steel processes and not treated for recovery
• Avoid misclassification as waste (Chapter 26 exclusions); ensure industrial use declaration
