8411.22 - Of a power exceeding 1,100 kW:

This HTS category, 8411.22, specifically classifies turbopropellers that have a power output exceeding 1,100 kW. Turbopropellers are a type of gas turbine engine that utilize a propeller for propulsion, commonly found in aircraft. The key distinguishing feature for classification under this heading is the engine's power rating; if the output is greater than 1,100 kW, it falls within this group.

This classification is differentiated from its sibling category, 8411.21, which covers turbopropellers with a power output not exceeding 1,100 kW. Therefore, the threshold of 1,100 kW is the primary determinant for placing a turbopropeller engine into either 8411.21 or this category, 8411.22. Both categories are part of the broader classification for turbojets, turbopropellers, and other gas turbines, and their parts.

Within HTS 8411.22, further subdivisions exist to refine classification. The subcategories include 8411.22.40.00 for aircraft turbines, indicating turbopropellers specifically designed for aerospace applications. The remaining turbopropellers exceeding 1,100 kW that do not fit the specific aircraft turbine definition are classified under the general subheading of "Other," denoted by 8411.22.80.00. This hierarchical structure allows for precise identification of the type and intended use of these powerful propulsion systems.
