Import Tips
• Ensure the copper foil thickness is 0.15 mm or less, excluding the FR4-PTFE backing, to meet the tariff item definition
• Document the refined copper content and the hybrid backing structure for CBSA review
• If the PTFE content is significant, verify whether the laminate could be classified as a plastic article instead
