Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nickel silver alloy (>5% nickel)
Copper-nickel-zinc alloys per note (c) fall under 7409.29 alloy plates.
If under 5mm thickness
Thinner plates/sheets of refined copper use lower thickness subheadings.
If shaped into copper tubes afterward
Post-import fabrication into tubular form changes to copper tube headings.

Import Tips & Compliance
• Submit spectrometry reports proving oxygen-free refined copper composition
• Document width/thickness precisely; strips <500mm wide still qualify as strip
• Ensure no surface treatment that could reclassify as 'worked' copper
