C10100 OF Copper Round Bar from Mexico
A 1-inch diameter round bar made from Oxygen-Free (OF) C10100 refined copper, used in electrical busbars and heat exchangers. It falls under HTS 7407.10.5050 as 'other' bars and rods of refined copper, excluding high-conductivity hollow rectangular bars. Refined copper ensures purity over 99.9% for superior conductivity.

Import Tips
• Provide mill test certificates verifying copper purity >99.9% to confirm refined status and avoid reclassification as alloy
• Declare exact dimensions and cross-section shape; 'other' excludes hollow rectangular high-conductivity bars
• Ensure EN or ASTM material specs match; common pitfall is mislabeling OFHC as standard ETP copper
