Product classification
HS code for Small gas turbine: 8411.81
Turbines, gas-turbines (excluding turbo-jets and turbo-propellers), of a power not exceeding 5000kW.
Classification of small gas turbine under HS 8411.81
The HS code 8411.81 is applied to gas turbines with a power output not exceeding 5,000 kW, excluding turbo-jets and turbo-propellers. This classification is situated within Chapter 84, which deals with nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8411 covers turbo-jets, turbo-propellers, and other gas turbines. The distinction between "other gas turbines" and aviation-specific turbines is crucial for correct classification. Subheading 8411.81 specifically targets industrial or marine gas turbines that fall below the 5,000 kW threshold. These units operate by compressing air, mixing it with fuel, and igniting it to drive a turbine. The classification depends on the mechanical function and the power rating. It is essential to distinguish these from steam turbines or internal combustion engines. The classification is guided by the technical parameters of the turbine's output, usually measured in kilowatts (kW) or megawatts (MW). For customs purposes, the power rating must be the continuous rated power as specified by the manufacturer's technical documentation.

Codes often confused with 8411.81
Common mistake. Small gas turbines are often confused with turbo-jets (8411.11) or turbo-propellers (8411.21). However, those codes are strictly for aircraft propulsion. Another common misclassification is HS code 8411.82, which is for gas turbines with a power exceeding 5,000 kW. Additionally, if the turbine is part of an electric generating set, it should be classified under heading 8502 rather than 8411. Steam turbines, which operate on a different thermodynamic cycle, belong under heading 8406.
Top exporters and importers of HS 841181 (the code used for small gas turbine), 2025
In 2025, the largest exporter of HS 841181 (the code used for small gas turbine) in UN Comtrade data was Singapore, with 18% of world exports; the largest importer in UN Comtrade data was the United Kingdom, with 12% 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).
