Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for land-based steam turbines
Parts of steam turbines fall under heading 8406, differentiated by turbine type (gas vs steam).
If parts of industrial gas turbines not specifically turbojets or turboprops
Other gas turbine parts may classify under 8411.99 if not exclusively for turbojets/turboprops.
If imported as gear components rather than turbine-specific
Gears and gearing elements shift to Chapter 84 heading 8483 for transmission components.
