Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If as individual turbine components like compressors
Separate parts of gas turbines classify under 8411.99 rather than complete assemblies.
If reciprocating engines modified for aircraft
If piston-based rather than gas turbine, falls under spark-ignition aircraft engines.
If power exceeding 1,100 kW
Higher power turbopropellers use 8411.22.40.00 subheading.
