Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the muntz metal is considered a copper-zinc base alloy rather than refined copper
This subheading covers copper-zinc base alloy plates, sheets and strip, which may be more appropriate if the alloy definition applies.
If the sheet is of a copper alloy not specified elsewhere
This subheading covers other copper alloy plates, sheets and strip, for alloys not classified under the specific alloy subheadings.
