Import Tips & Compliance
• Ensure the polyurethane coating is declared as a minor surface treatment that does not change the wire's classification
• Provide a mill certificate or test report showing the copper content is at least 99.85% to qualify as refined copper
• Be prepared to explain why the wire is not classified as an insulated conductor of heading 85.44 if questioned by CBSA
