Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper content exceeds 60% making it primarily copper-based
High-copper nickel alloys may classify under Chapter 74 copper tubes instead.
If for boiler/pressure vessel certified variants
Specific end-use tubes for boilers move to iron/steel headings in Chapter 73.
If aluminum-nickel composite rather than pure nickel alloy
Aluminum tubes/pipes with nickel elements fall under Chapter 76.
