Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the copper content exceeds the zinc content
The subheading within 2620 is determined by the predominant metal; copper-dominant residues are classified under 2620.30.
If the residue is destined for arsenic extraction
Chapter subheading note 2 assigns residues containing arsenic to 2620.60 when used for arsenic or metal extraction.
If the main metal is not zinc
Residues with a main metal other than zinc are classified under the 'other' subheading of heading 2620.

Import Tips & Compliance
• Confirm the slag is not a byproduct of iron or steel manufacturing, as that would change the tariff classification
• Maintain records of the smelting process and chemical composition to present to CBSA upon request
• Verify whether the arsenic content triggers any import restrictions under Canadian hazardous materials regulations
