Hot-Dip Galvanizing Residue
Residue ash collected from hot-dip zinc galvanizing lines, composed primarily of zinc compounds with arsenic impurities. This material is used industrially as a basis for manufacturing zinc compounds or for metal extraction, which places it under tariff item 2620.19.00 for slag and ash containing mainly zinc.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the residue is hard zinc spelter rather than ash
Hard zinc spelter is a distinct form of zinc residue classified separately from ash.
If the residue contains mainly metals other than zinc
Residues containing mainly other metals are classified under the 'other' subheading.

Import Tips & Compliance
• Ensure the residue is not from iron or steel manufacturing, as those fall under a different heading
• Provide a certificate of analysis showing zinc content to support classification
• Check if the arsenic content triggers any hazardous waste import permit requirements under Canadian environmental regulations
