Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a cathode or section of cathode
Cathodes are a different unwrought form of refined copper, not billets.
If the billet is not refined copper but a copper alloy
Alloy billets fall under other refined copper or alloy headings.
