Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If importing fuel elements for the reactor
Non-irradiated fuel cartridges are classified separately from the reactor itself.
If classified as nuclear reactor parts rather than complete assembly
Certain machinery components may fall under gas turbine-like provisions if not deemed a full reactor.
If for isotopic separation apparatus integrated within
Machinery for isotopic separation is in a different subheading of 8401.
