Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If municipal or mixed waste fly ash
Municipal incineration residues explicitly go to 2621 per chapter exclusions.
If aluminum industry residues
Specific aluminum slag/ash classified separately in 2619.
If chemically treated residues
Advanced processing into chemical preparations shifts to Chapter 38.

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.
Lead Smelter Dust Ash
Fine ash and dust residues from lead smelting operations containing arsenic and trace metals, suitable for arsenic or metal compound production. Classified in 2620.99.75 due to being unprocessed industrial residues with lead content below 2% by weight.
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.
Precious Metal Recovery Slag
Slag residues from precious metal refining with arsenic traces, used in further extraction processes. Under 2620.99.75 for unprocessed form with negligible Cu/Pb/Zn.
Industrial Arsenic Furnace Ash
Ash from arsenic production furnaces in metal industries, containing metal compounds for chemical use. 2620.99.75 due to being residue not advanced and compliant with metal limits.
