Oxygen-Free High Conductivity Copper Billets from Mexico
Oxygen-free high conductivity (OFHC) copper billets feature ultra-low oxygen content (<10 ppm) for superior electrical performance in billets used for magnet wire. They qualify under HTS 7403.13.00.00 as unwrought refined copper billets. Ideal for semiconductors and RF applications due to high purity.

Import Tips
• Submit oxygen content analysis certificates; levels above 50 ppm may reclassify as ETP rather than OFHC
• Use ISRI scrap specifications if importing recycled content billets to qualify for lower duties
• Label as 'not for remelting into alloys' to prevent heading 7405 master alloy classification
