Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If zinc predominates over nickel (<5% Ni)
Becomes copper-zinc base alloy (brass) per note (a), not nickel-silver.
If imported as unfinished tube sections for further fabrication
Articles of copper alloys not elsewhere specified cover unfinished or waste forms.
If assembled into complete heat exchanger units
Finished machinery parts like condenser assemblies shift to Chapter 84 machinery headings.
