Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel base alloy
Copper-nickel alloys with nickel predominant and zinc ≤1% are under separate subheading per note (d).
If high purity copper scrap >99% Cu
Pure copper waste without significant alloying elements falls under unalloyed copper scrap heading.
If containing >2% slag/ash impurities
Slag/dross containing copper classified in Chapter 26 as mineral waste, not clean metal scrap.
