Roasted Zinc Ore Residue with Silver
Ash-like residue from roasting zinc concentrates, rich in zinc with recoverable silver and arsenic traces, destined for hydrometallurgical recovery. Falls under 2620.19.60.40 as 'other' zinc-containing residues with silver content, per hierarchy excluding iron/steel origins. Industrial use only for metal extraction.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mainly lead instead of zinc
Hierarchy shifts to 'other metals' subheading if zinc is not predominant.
If for unroasted zinc ore residues
Roasting state determines heading; unprocessed falls under roasted/calcined ores in 2613.
If processed into electrical waste residues
Advanced processing may classify as electrical scrap rather than raw industrial slag.

Import Tips & Compliance
• Submit detailed chemical composition report highlighting zinc majority and silver assay for accurate statistical reporting
• Confirm industrial extraction intent via end-user certificates to prevent misclassification as waste
• Watch for particle size documentation if coarse; avoid blending with iron residues to maintain 2620 eligibility
