Product classification
HS code for Gas turbine parts: 8411.99
Turbines, parts of gas turbines (excluding turbo-jets and turbo-propellers).
Classification of gas turbine parts under HS 8411.99
HS Code 841199 is the specific classification for parts of gas turbines, excluding those used for aircraft propulsion such as turbo-jets and turbo-propellers. Gas turbines classified under 8411 are internal combustion engines where the working fluid is a gas, typically used in industrial power generation, mechanical drive applications, or marine propulsion. The parts classified under 841199 must be identifiable as being suitable for use solely or principally with these specific turbines. This classification follows the General Rules of Interpretation and Section XVI Note 2(b), which directs parts that are not specified elsewhere to be classified with the machines they are intended for. The technical complexity of these parts, often involving high-temperature resistant alloys and precision engineering, necessitates a specific code to track trade data accurately for the energy and industrial sectors. This code excludes parts for turbo-jets (841191) and general-purpose parts like bolts or gaskets which are classified by their own material headings.

Codes often confused with 8411.99
Common mistake. The most common misclassification occurs with 841191, which is strictly for parts of aircraft turbo-jets or turbo-propellers. Importers also frequently confuse these with steam turbine parts (840690) or general engine parts (840999). It is vital to verify the end-use of the turbine to distinguish between industrial gas turbines and aviation engines.
Top exporters and importers of HS 841199 (the code used for gas turbine parts), 2025
In 2025, the largest exporter of HS 841199 (the code used for gas turbine parts) in UN Comtrade data was the United States, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 14% 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).
