Import Tips & Compliance
• Use ISRI scrap specifications for consistent grading and valuation
• Screen for arsenic content if residues suggest Chapter Note (b) applicability
• File for binding rulings if alloy composition blurs lines with finished products

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.
Galvanized Steel Processing Zinc Dross
Zinc dross generated during hot-dip galvanizing of steel, skimmed from zinc kettles, mainly zinc oxides and compounds. HTS 2620.19.30.00 applies as non-ferrous slag/residue for industrial metal recovery, per Chapter Note (a). Commonly recycled in secondary zinc smelters.
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.
