Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel-zinc (nickel silver)
Nickel ≥5% per note (c) reclassifies to nickel silver alloys under 7409.19.
If further processed into foil-backed laminates
Composite materials with non-copper layers move to tubes/pipes or other worked forms.
If for industrial tube manufacturing use vs retail
End-use as tube components may shift to unwrought or semi-manufactured forms.
