Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically refined to zinc bars or ingots
Advanced processing elevates it from residue to unwrought zinc under 7901/7902.
If in granular or powder form post-crushing
Physical form changes may shift within 2620, but dross/skimmings are specifically 2620.19.30.
If chemically treated as a compound
Prepared chemical compounds of zinc residues may classify as chemical preparations.

Import Tips & Compliance
• Conduct particle size analysis if needed, though not directly applicable; focus on zinc assay compliance
• Avoid bulk packaging that mimics ore shipments, which could lead to Chapter 26 misrouting
• Partner with certified labs for pre-shipment testing to confirm 'mainly zinc' composition

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.
Zinc Skimmings from Die Casting
Zinc skimmings are surface impurities removed from molten zinc in die casting operations, primarily zinc-rich with metal compounds. Classified under HTS 2620.19.30.00 for residues used in industry for zinc extraction or chemical manufacturing, aligning with Chapter Note (a). These are byproducts suitable for recycling.
Secondary Zinc Smelter Skimmings
Skimmings from recycling zinc in secondary smelters, containing zinc dross with impurities for further extraction. Falls under HTS 2620.19.30.00 as zinc-based industrial residues, excluding ferrous or waste ash per Chapter Notes. Used as feedstock for zinc recovery.
Zinc Alloy Melting Dross
Dross skimmed during melting of zinc alloys for manufacturing, primarily zinc with compound residues. HTS 2620.19.30.00 covers this as 'other' zinc dross for industrial use in metal/compound production. Recovered for zinc reclamation.
