Zinc Dross from Galvanizing Operations
Zinc dross consists of impurities and oxide layers skimmed from molten zinc during galvanizing processes, containing mainly zinc with traces of other metals and compounds. It falls under HTS 2620.19.30.00 as a residue from zinc processing used for metal recovery or chemical compound production, per Chapter Note (a). This material is typically reprocessed to extract zinc.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Residues from incineration of municipal waste are excluded from 2620 and classified separately in 2621.
If refined to zinc dust or powders
Processed zinc in powder form changes from residue to primary zinc products under Chapter 79.
If containing mainly lead instead of zinc
Slags and residues primarily of lead fall under 2619, based on main metal content.

Import Tips & Compliance
• Provide assay reports certifying zinc content without deductions as per statistical notes for accurate declaration
• Ensure documentation proves industrial use for metal extraction to avoid misclassification under heading 2621
• Verify absence of municipal waste incineration origins to comply with Chapter Note exclusions
