Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unthreaded
Unthreaded brass pipe nipples fall under the 'not threaded' subheading within the same copper-zinc alloy category.
If made of iron or steel
Iron/steel pipe nipples are classified in Chapter 73 for ferrous tube fittings, not copper alloys.
If of refined copper (not alloy)
Fittings of pure copper without significant zinc alloying move to the refined copper fittings heading.

Import Tips & Compliance
• Verify alloy composition meets copper-zinc base alloy definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates
• Ensure NPT threading standards compliance; mismatched threads lead to customs reclassification or rejection
• Provide pressure ratings and plumbing end-use documentation to avoid misclassification as industrial machinery parts
