Product classification
HS code for Hydraulic turbine parts: 8410.90
Turbines, parts of hydraulic turbines and water wheels, including regulators.
Classification of hydraulic turbine parts under HS 8410.90
Parts for hydraulic turbines and water wheels are classified under HS code 841090. Heading 8410 is dedicated to water turbines and water wheels, which are machines that transform the energy of flowing or falling water into mechanical energy. Following the General Rules of Interpretation and the specific notes for Section XVI, components that are uniquely designed for these turbines are categorized in the 841090 subheading. This includes both the massive structural components of hydroelectric turbines and the precision control mechanisms required to manage water flow. The classification is distinct from general hydraulic motor parts (841290) because 8410 specifically addresses turbines used in power generation and large-scale water management. The inclusion of 'regulators' in the HS description for 841090 is a specific instruction to include the complex governors and control systems that maintain the turbine's rotational speed.

Codes often confused with 8410.90
Common mistake. Parts for steam turbines (840690) or gas turbines (841199) are frequently confused with hydraulic turbine parts. It is essential to identify the driving medium (water vs. steam/gas). Additionally, general hydraulic valves used in the control system might be classified under 848120 rather than 841090 if they are not specifically designed solely for the turbine assembly.
Top exporters and importers of HS 841090 (the code used for hydraulic turbine parts), 2025
In 2025, the largest exporter of HS 841090 (the code used for hydraulic turbine parts) in UN Comtrade data was China, with 28% of world exports; the largest importer in UN Comtrade data was the United States, with 7.2% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 841090, not only hydraulic turbine parts.

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).
