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 high antimony/beryllium content
Residues rich in specific metals like antimony are separated into dedicated subheadings.
If derived from steelmaking slag
Iron/steel manufacturing residues are excluded and classified in Chapter 72.
If copper ores in raw form
If minimally processed ore rather than smelter residue, it falls under ore headings.

Import Tips & Compliance
• Use certified lab assays for metal content reporting without deductions per statistical notes
• Document origin from non-ferrous processes to comply with Chapter 26 hierarchy
• Beware of particle size misinterpretation; not subject to iron ore coarseness notes
Related Products under HTS 2620.99.75
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.
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.
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.
