Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Chapter note excludes such ash/residues from 2620, directing to 2621 for waste incineration products.
If roasted residues specifically from zinc/lead production
Specific heading 2613 covers roasted zinc/lead residues, taking precedence over general 2620.
If ferrous slag from iron/steel manufacture
Ferrous metallurgical slags fall under Chapter 72, excluded from 2620 scope.

Import Tips & Compliance
• Provide detailed assay certificates showing metal/arsenic content and absence of vanadium/silver/gold to avoid reclassification
• Declare as unadvanced residues; any chemical treatment may shift to 2620.19 or 2621
• Comply with EPA/TSCA import notices for arsenic-bearing materials to prevent customs holds
