Import Tips
• Maintain purity certificates (e.g
• OFHC grade) to prove refined copper status
• Ensure the product is not considered 'unwrought' (e.g
• wire-bars) which would fall under heading 74.03
• Verify the rectangular cross-section thickness exceeds one-tenth of the width to qualify as a bar, not a plate
