Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper predominates (>50%)
Nickel alloys where copper exceeds nickel content shift to copper alloy classifications in Chapter 74.
If of ball-bearing steel composition
High-nickel alloys meeting strict ball-bearing steel specs from Chapter 72 note (h) have separate subheading.
If hot-rolled rather than cold-formed
Same high-nickel composition but hot-rolled processing moves to Chapter 72 hot-rolled bars and rods.

Import Tips & Compliance
• Include UNS N04400 designation and chemical analysis proving Ni-Cu dominance for classification verification
• Document cold-finishing parameters (drawing, turning) without subsequent surface treatments
• Avoid misclassification by distinguishing from copper-nickel alloys under Chapter 74
