Import Tips
• Obtain copper purity certificates from accredited labs to confirm refined status and avoid reclassification as master alloys
• Ensure cathode thickness and dimensions meet standard specifications to qualify as unwrought forms
• Declare exact copper content percentage; impurities over certain thresholds may shift to alloy headings
