Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nickel-enhanced admiralty brass
Nickel admiralty becomes nickel silver if Ni ≥5%, separate subheading.
If machined into finished valve stems
Finished articles of copper alloys classified by function, not material.
If pump shafts or marine propeller components
Pump parts take machinery classification over tube material.

Import Tips & Compliance
• Certify tin <3% to avoid bronze misclassification; naval brass straddles the line
• For yacht/marine use, may qualify for temporary importation under TIB without duty
• Specify 'drawn' vs 'extruded'; different manufacturing affects allowable tolerances
