Product classification
HS code for Turboprop parts: 8411.91
Turbines, parts of turbo-jets and turbo-propellers.
Classification of turboprop parts under HS 8411.91
The classification of turboprop parts under HS code 8411.91 is governed by the General Rules of Interpretation (GRI) 1 and 6, as well as the Section XVI Note 2, which dictates the classification of parts of machinery. Heading 8411 covers turbo-jets, turbo-propellers, and other gas turbines. Subheading 8411.91 is specifically reserved for parts of turbo-jets or turbo-propellers. To be classified here, a component must be identifiable as being suitable for use solely or principally with a turboprop engine. This includes high-precision components designed to withstand the extreme thermal and mechanical stresses of aviation. Unlike general airframe components, these parts are classified based on their integral function within the power plant. The distinction is critical because it separates engine-specific components from general aircraft parts, ensuring that specialized aerospace engineering standards are reflected in the customs documentation. Proper classification requires technical documentation verifying that the part is indeed a component of the engine assembly rather than a secondary system.

Codes often confused with 8411.91
Common mistake. A frequent error is classifying these items under HS code 8803, which covers general parts of goods of heading 8801 or 8802 (aircraft). However, according to Section XVI Note 2(a), parts which are goods included in any of the headings of Chapter 84 or 85 are in all cases to be classified in their respective headings. Therefore, engine parts must stay in 8411. Another common mistake is using 8411.99, which is a residual category for parts of other gas turbines, whereas 8411.91 is the specific provision for turbo-jets and turboprops.
Top exporters and importers of HS 841191 (the code used for turboprop parts), 2025
In 2025, the largest exporter of HS 841191 (the code used for turboprop parts) in UN Comtrade data was the United Kingdom, with 24% of world exports; the largest importer in UN Comtrade data was Singapore, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about turboprop parts
What is the HS code for Turboprop parts?
The HS code for Turboprop parts is 841191 (Turbines; parts of turbo-jets and turbo-propellers). The primary HS code for parts of turbo-jets and turbo-propellers is 8411.91.
How do I classify Turboprop parts for customs?
Turboprop parts is classified under HS code 841191 — Turbines; parts of turbo-jets and turbo-propellers. This is a 6-digit subheading level code.
Does this code include the propeller itself?
No, propellers and rotors for aircraft, even if used with a turboprop engine, are typically classified under HS code 8803.01 or 8807.10 depending on the specific tariff version, as they are considered parts of the aircraft's propulsion system rather than the internal engine assembly.
Which countries are the top exporters of turboprop parts (HS 841191)?
