HS Code for Hydraulic turbine parts

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.

Products Included

• Turbine runners and blades
• Wicket gates and guide vanes
• Turbine housings and spiral casings
• Hydraulic turbine regulators and governors
• Draft tube liners
• Stay rings and discharge rings

Common Misclassification

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.

FAQ

What is the HS code for hydraulic turbine parts?

The HS code for parts of hydraulic turbines, including water wheels and their regulators, is 841090.

Are electronic controllers for turbines included in 841090?

Purely electronic control panels are often classified under 8537, but mechanical or hydraulic regulators specifically for turbine speed control are included in 841090.
