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 containing mainly zinc
High zinc content (>40%) residues fall under specific zinc subheadings within 2620.
If calcined or roasted for recovery
Processed residues advanced by roasting shift to subheading for metal recovery materials.
If further chemically processed
Advanced treatment into residual chemical products moves it out of Chapter 26 slag residues.

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.
Zinc Refinery Slag Residue
Slag residues from zinc refining processes with arsenic and metal impurities, used as basis for metal extraction. HTS 2620.99.75 applies to these unadvanced, untreated materials ensuring zinc content stays under 2% threshold.
Arsenic-Rich Smelter Flue Dust
Flue dust collected from non-ferrous metal smelters containing primarily arsenic with minor metals, for extraction or compound use. Fits 2620.99.75 as unprocessed residue not intended for Cu/Pb/Zn recovery.
Mixed Non-Ferrous Ash Residue
Ash from incineration of non-ferrous metal production waste, containing arsenic and compounds for industrial recovery. 2620.99.75 covers this as other unadvanced residues with controlled low Cu/Pb/Zn levels.
