Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Te content makes it copper-tellurium alloy
Specific Cu-Te alloys with Te predominant over other minor elements classify as brasses.
If unwrought billets
Unwrought alloy copper (not refined) goes to 7403.12.
If coated for welding electrodes
Coated welding electrodes become Chapter 83 cored wire.
