Import Tips
• Due to precious metal content, verify whether the residue also falls under Chapter 71 rules for precious metals; if so, additional declarations may be required
• Provide a detailed assay report to the CBSA to substantiate the copper content below 94% by weight
• Check if the residue qualifies as hazardous waste under Canadian environmental regulations, which may require permits beyond customs clearance
