Zinc Galvanizing Kettle Dross
Dross and skimmings collected from molten zinc baths used in hot-dip galvanizing of steel sheets and structures. Falls under HTS 7902.00.00.00 as zinc waste and scrap due to its form as oxidation impurities and metallic zinc mixture suitable only for recycling.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly zinc oxide from roasting processes
Zinc oxide, whether pure or from residues, is classified under Chapter 28 chemicals, not metal scrap.
If ferro-zinc alloy waste from steelmaking
Ferro-zinc alloys are under Chapter 72 for iron and steel, based on iron predominance or specific alloy composition.
If sold as leaching residues with other metals
Complex mineral processing residues containing zinc are Chapter 26, not simple metal scrap.

Import Tips & Compliance
• Submit lab assays confirming zinc predominance (>50% by weight) to distinguish from iron-zinc alloys under Chapter 72
• Comply with Basel Convention if transboundary hazardous waste movement is involved due to potential heavy metal leachates
• Declare exact source (e.g
• galvanizing plant) to prevent misclassification as primary zinc oxide under 2817
