Import Tips
• Verify copper thickness excludes backing and does not exceed 0.15 mm; provide lab test reports for customs verification
• Include material composition certificates confirming plastics-impregnated glass base and refined copper alloy compliance
• Avoid misclassification as single-sided by clearly documenting 'copper on both sides' in invoices and packing lists
