Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel alloy instead of bronze
Copper-nickel base alloys have separate provisions excluding >1% zinc content.
If shaped into fittings/connectors
Profiles further worked into pipe fittings classified in 7412, not raw profiles.
If unwrought refined copper
Unwrought forms precede worked profiles; must be extruded profile for 7407.

Import Tips & Compliance
• Submit chemical analysis verifying tin predominance over other elements except limited zinc (<10%)
• Document end-use application to distinguish from tube/pipes in 7411
• Ensure profiles remain extruded shapes, not drawn/manufactured tubes
