Import Tips
• Verify copper purity meets 'refined copper' standards via assay certificates to avoid reclassification
• Measure thickness excluding any temporary handling layers; provide caliper test reports
• Ensure no adhesive backing; declare as 'not backed' with photos or cross-sections if audited
