Zinc Electrolyte Purification Slag Silver
Slag generated during zinc electrolyte purification in electrowinning plants, primarily zinc-based with silver precipitates and arsenic. Classified in 2620.19.60.40 for silver-content zinc residues used in metal recovery, per legal definitions excluding iron/steel and municipal waste. Basis for silver extraction processes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If enriched silver compounds extracted
Post-processing into chemical compounds of silver moves to Chapter 28 inorganics.
If contaminated with steelmaking residues
Any iron/steel manufacture link excludes from 2620 per chapter notes.
If for non-arsenic, non-zinc predominant residues
Lacks zinc main content or arsenic, shifting to other residues.

Import Tips & Compliance
• Include electrowinning process flowcharts and silver assay reports for customs; report gross metal content
• Certify non-municipal origin; common issue is moisture content affecting weight-based duties
• Use ISPM-15 compliant pallets for transport; declare arsenic levels for EPA compliance
