Nickel Silver Hollow Extruded Profile for Musical Instrument Valves
Hollow extruded profile from copper-nickel-zinc alloy (nickel silver, 65Cu-18Ni-17Zn), used in manufacturing trumpet and valve components for its acoustic properties and corrosion resistance. Falls under HTS 7407.29.16.10 as a profile of copper-nickel-zinc base alloy with nickel ≥5%. The specific cross-sectional shape qualifies it as a profile rather than bar.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If solid cross-section
Solid profiles of same alloys fall under non-hollow subheading; only hollow profiles get .16.10 suffix.
If imported pre-machined as finished musical instrument part
Completed valve components classify under musical instrument parts, not raw material profiles.
If of refined copper without alloying elements
Pure copper profiles have separate heading; alloy content determines Chapter 74 subheading.

Import Tips & Compliance
• Include chemical analysis confirming nickel ≥5% and zinc/tin limits per subheading note to distinguish from brass
• Label shipments clearly as 'hollow profiles' with cross-section diagrams; avoid 'tube' terminology to prevent misclassification
• For musical instrument suppliers, provide end-use letters showing machining required, supporting unfinished profile status
