C10100 Oxygen-Free Electronic (OFE) Copper Ingots
Ultra-high purity refined copper ingots with less than 0.0005% oxygen, cast for electronic applications. Falls under HTS 7403.19.00.00 as unwrought refined copper not meeting the highest purity threshold, ideal for remelting into wire or components.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper purity is 99.99% or higher
Exceeds the purity threshold for the more specific refined copper subheading 7403.11.
If made from copper-zinc brass alloys
Copper-zinc base alloys (brasses) per subheading note (a) classify under separate 7403.21 unwrought alloys.
If anodes for electrolytic refining rather than refined product
Unrefined copper anodes for further processing fall under heading 7401, not refined copper.

Import Tips & Compliance
• 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
