Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel-zinc (nickel silver)
Nickel silvers (≥5% Ni) use 7407.12 per note (c); phosphor bronze lacks nickel dominance.
If copper-nickel base alloy
Note (d) copper-nickel alloys (≤1% Zn, Ni dominant) classify under 7409.90.
If parts of compressors after fabrication
Finished compressor diaphragms become parts under 8414.90, not raw sheet.
