HS Code 8411.91 – Turbines; parts of turbo-jets and turbo-propellers
HS code 8411.91 is the 6-digit subheading for turbines, parts of turbo-jets and turbo-propellers. It is used for turbine blades, compressor rotors, combustion chambers, nozzles and engine casings.
What HS 8411.91 covers
This category encompasses the specialized components and parts essential for turbo-jet and turbo-propeller aircraft engines. These parts are critical for both the manufacturing of new engines and the vital maintenance, repair, and overhaul (MRO) of existing ones, ensuring the safety and operational efficiency of aircraft globally. International trade is characterized by a complex global supply chain involving original equipment manufacturers (OEMs), their extensive network of suppliers, and specialized MRO facilities. Importers include aircraft engine manufacturers, airlines with in-house MRO capabilities, and independent repair shops. Exporters are typically the engine OEMs or their authorized parts distributors. The trade is highly regulated, demanding stringent quality control and traceability, reflecting the paramount safety role of these components in the aviation industry.

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).
