Zinc Smelter Silver-Bearing Slag
Residue from zinc smelting processes containing mainly zinc along with silver content and arsenic compounds, used for metal recovery. Classified under HTS 2620.19.60.40 due to its primary zinc composition and silver assay, fitting Chapter 26 notes for industrial residues excluding iron/steel slag. Not suitable for direct use without processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Chapter notes exclude such ash/residues from 2620, directing to heading 2621 for household waste products.
If primarily a tungsten-bearing residue
Shifts to 2619 if main metal is tungsten rather than zinc, based on predominant metal content.
If from iron or steel manufacture
Ferrous slag falls under Chapter 72, excluded explicitly from 2620 by heading scope.

Import Tips & Compliance
• Report silver content via assay certificate without deductions per statistical notes; include lab analysis for customs valuation
• Verify absence of municipal waste incineration origin to avoid reclassification under 2621; provide smelter process documentation
• Ensure hazardous material declarations for arsenic content; common pitfall is underreporting metal quantities leading to penalties
