Import Tips
• Require mill test certificates confirming 99.95% minimum copper purity and compliance with ASTM B115 standards
• Verify country of melt and pour documentation as duty rates vary significantly by origin (e.g
• duty-free from FTA countries)
• Ensure cathodes are free of surface contaminants; customs may reject if oxidized or contaminated beyond specified limits
