Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pipe is made of a copper-zinc base alloy (brass)
This subheading covers copper-zinc base alloy tubes and pipes, which would apply if the alloy composition fits the brass definition instead.
If the pipe is made of a copper-nickel base alloy with a different composition
This subheading specifically covers copper-nickel base alloy tubes and pipes, but only if the alloy meets the exact definition in subheading note (d).

Import Tips & Compliance
• Ensure the pipe's alloy composition is documented with a mill certificate to confirm it qualifies as a copper-nickel base alloy under subheading note (d)
• Verify the pipe's dimensions and wall thickness meet the definition of tubes and pipes in Section XV note 9(e) to avoid reclassification
