Galvanizing Plant Zinc Ash Gold Impurity
Ash from hot-dip galvanizing plants, mainly zinc dross with minor gold content from alloy recycling, for metal recovery. Classified in HTS 2620.19.60.50 as zinc-dominant residues containing metals/gold, not from iron/steel primary production. Industrial use only.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other roasted/unroasted zinc residues
Non-arsenic/metal compound zinc materials may fall under general zinc ore residues.
If from waste incineration processes
Any municipal or general waste ash excludes from 2620 per chapter note.
If refined zinc dust/powder form
Processed zinc products without slag characteristics shift to Chapter 79.

Import Tips & Compliance
• Document galvanizing process to distinguish from steel slag under Chapter 72
• Use certified labs for gold assay to comply with no-deduction statistical quantity rules
• Prepare for environmental queries; prove non-municipal waste origin per chapter exclusions
