Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the copper content exceeds the zinc content
Heading 2620 covers slag, ash and residues containing metals; if copper is the main metal, it would be classified under the copper-specific subheading.
If arsenic content is significant and the residue is used for arsenic extraction
Subheading note 2 directs slag, ash and residues containing arsenic to subheading 2620.60 when used for arsenic or metal extraction.
If the residue contains metals other than zinc as the main component
Residues containing mainly metals other than zinc, iron, or steel are classified under the 'other' subheading of heading 2620.

Import Tips & Compliance
• Ensure the residue is not from iron or steel manufacture, as that would fall under a different heading
• Be prepared to provide a certificate of analysis showing the zinc, copper, and arsenic content to support classification
• Verify whether the material meets the definition of 'ores' under Chapter 26 note 2, as processed materials may be excluded
