More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the copper content is 94% or more by weight
Higher-purity copper scrap would fall under the residual item for other waste and scrap.
If the lining scrap is derived from spent anodes and is not alloyed
Spent anode-derived waste with copper below 94% is covered by this item.
If the lining is predominantly plastic or rubber rather than copper
Non-metal tank linings would be classified as plastic or rubber waste, not copper scrap.

Import Tips & Compliance
• Ensure the scrap is thoroughly cleaned of electrolyte residues before shipping to avoid classification as hazardous waste
• Provide documentation showing the copper content is below 94% by weight, as the presence of adherent residues may complicate the assay
• Confirm with the CBSA whether the lining material itself (e.g
• rubber or plastic) affects classification under the General Interpretative Rules
