Zinc Smelter Slag with High Zinc Content
Residue from zinc smelting processes containing primarily zinc compounds and arsenic, used in industry for metal recovery. Classified under HTS 2620.19.60.30 due to its main zinc content and suitability for extracting metals or manufacturing chemical compounds. Excludes steel production residues.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Ash and residues from municipal waste incineration are excluded from 2620 and fall under heading 2621.
If primarily from lead or zinc smelting slag
Slag and residues from lead-zinc smelting may classify under 2619 if not mainly zinc or meeting 2620 criteria.
If from iron or steel manufacture
Ferrous slag from iron or steel production is classified in Chapter 72, not 2620.

Import Tips & Compliance
• Provide assay certificates detailing zinc and arsenic content to verify classification and quantity reporting without deductions
• Ensure documentation proves industrial use for metal extraction to avoid reclassification under waste headings
• Comply with environmental regulations on hazardous residues containing arsenic during import
