Import Tips & Compliance
• Ensure the wire is declared as refined copper wire, not as an insulated article of Chapter 85, to benefit from the correct tariff classification
• Keep certificates of analysis showing copper purity (at least 99.85% by weight) to support the refined copper claim
• Verify whether the enamel coating is considered a minor processing step that does not alter the wire's essential character
