Import Tips
• Provide mill test certificates verifying 99.99% copper purity to confirm refined status and avoid reclassification as alloy
• Ensure billets meet ASTM B49 standards for refined copper; improper documentation can lead to higher duties under alloy headings
• Declare exact dimensions and weight accurately, as billets over certain sizes may trigger anti-dumping scrutiny
