Import Tips
• Ensure the copper content meets the definition of refined copper (≥99.85% by weight) to qualify for this tariff item
• Provide a mill certificate or assay report to the CBSA to support classification
• Verify whether the wire-bar ends are simply tapered or worked; if worked beyond simple tapering, it may be classified elsewhere
