Import Tips
• 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
