Import Tips & Compliance
• Ensure the wire's diameter is accurately measured and documented, as classification depends on it being over 9.5 mm but not over 12.7 mm
• Verify the copper is refined (at least 99.85% pure) and provide a mill certificate to the CBSA if requested
• Check if the wire qualifies for preferential duty treatment under a free trade agreement by providing a valid certificate of origin
