Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosphor bronze composition
Specific copper-tin-phosphorus alloys have statistical suffixes within thick 'other' category.
If fabricated into tubes/pipes
Post-import forming into tubular products shifts to Chapter 73 iron/steel pipes if applicable.
If in unwrought form
Not plates/sheets but castings/billets of copper-zinc alloys use refined copper unwrought headings.
