Product classification
HS code for Commercial steam turbines: 8406.82
Turbines, steam and other vapour turbines, (for other than marine propulsion), of an output not exceeding 40MW.
Classification of commercial steam turbines under HS 8406.82
Commercial steam turbines with an output not exceeding 40 MW are classified under HS code 8406.82. Heading 8406 covers steam turbines and other vapor turbines. The classification structure for this heading first distinguishes between turbines for marine propulsion (8406.10) and "other" turbines. Within the "other" category, the subheadings are divided by power output. Subheading 8406.82 is specifically for turbines with an output not exceeding 40 MW. These machines convert the thermal energy of pressurized steam into mechanical work, typically to drive an electrical generator or mechanical equipment like pumps and compressors. The classification is strictly based on the technical output rating and the intended non-marine application of the turbine.

Codes often confused with 8406.82
Common mistake. The most common error is misclassifying the turbine under 8406.81, which is for turbines with an output exceeding 40 MW. Accurate technical documentation of the megawatt (MW) rating is essential. Another misclassification occurs with 8406.10 if the turbine is intended for a ship, as marine propulsion turbines have their own dedicated category regardless of their power output. Finally, gas turbines should not be confused with steam turbines; gas turbines are classified under heading 8411.
Top exporters and importers of HS 840682 (the code used for commercial steam turbines), 2025
In 2025, the largest exporter of HS 840682 (the code used for commercial steam turbines) in UN Comtrade data was Japan, with 20% of world exports; the largest importer in UN Comtrade data was China, with 11% 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).
