Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel alloy instead of beryllium
Different alloy base per subheading notes shifts within same form dimensions but other alloy type.
If End-use as machinery parts classified by function in Chapter 84, not material.
If under 0.15 mm thickness
Thinner foil forms move to Chapter 74 heading 7408 for clad or thin sheets.
