Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing >1% zinc
Exceeds copper-nickel base alloy limit, potentially qualifying as copper-zinc if zinc predominates.
If nickel content dominates overall alloy
High-nickel alloys may shift to Chapter 72 iron/steel if reclassified by composition.
If for refined copper without alloying
Pure refined copper excludes alloys entirely.
