Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from municipal waste incineration
Ash or residues from household waste incineration fall under heading 2621, not 2620.
If primarily containing lead
Slag with mainly lead shifts to 2619, as classification follows dominant metal content.
If from iron or steel manufacture
Ferrous slag residues are classified under Chapter 72, excluding them from Chapter 26 heading 2620.

Import Tips & Compliance
• Provide assay reports certifying main zinc content and arsenic presence to confirm classification under 2620.19.60
• Ensure documentation proves industrial use for metal extraction to avoid reclassification as waste
• Comply with EPA hazardous waste regulations due to arsenic content during import
