Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for reactor pressure vessel imported separately
Large-scale pressure vessels may classify as tanks/reservoirs if not assembled.
If considered heat exchange units only
Standalone heat exchangers from reactors go to Chapter 84 machinery.
If for unmanned handling machinery within reactor
Fuel handling robots may classify as industrial robots separately.
