Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If auxiliary plant machinery for steam turbines
Parts and accessories for steam turbines (not generating sets) fall under 8406.90
If imported as separate AC generator only
Generators without prime movers classify under heading 8503
If hydraulic turbine-generator instead of steam
Water-powered turbine sets use 8410; steam uses 8502.39.0040
