Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the copper content exceeds the zinc content
Brass is a copper-zinc alloy; if copper predominates in the residue, classification under the copper subheading would apply.
If the residue is used for arsenic extraction
Subheading note 2 assigns residues containing arsenic to 2620.60 when used for extraction of arsenic or metals.
If the main metal is neither zinc nor copper
Residues containing mainly other metals are classified under the residual subheading of heading 2620.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Confirm the residue is not classified as copper slag, as the main metal content determines the subheading
• Provide a certificate of analysis showing zinc as the predominant metal
• Be aware that arsenic content may subject the material to additional environmental controls under Canadian law
