Import Tips
• Provide mill test reports verifying oxygen content below 10 ppm to distinguish from standard ETP copper
• Use proper packaging to prevent surface oxidation during transit, which could affect unwrought classification
• Avoid wire bar shapes; irregular ingot forms preserve unwrought status
