Import Tips
• Verify copper purity meets 'refined copper' standards (≥99.85% Cu) with mill test certificates to avoid reclassification
• Measure thickness excluding backing precisely; provide lab reports if audited, as exceeding 0.15mm shifts to 7410.22
• Declare backing material accurately on entry docs to prevent penalties for misdescription
