HS Code for Small steam turbines
Small steam turbines are classified under HS code 8406.82 based on the General Rules for the Interpretation of the Harmonized System (GRI). Chapter 84 encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Within this chapter, heading 8406 is specifically dedicated to steam turbines and other vapor turbines. The classification process involves evaluating the primary function of the machinery and its technical specifications. Subheading 8406.82 is reserved for turbines that are not intended for marine propulsion and have a rated power output not exceeding 40 megawatts (MW). These turbines operate by converting the thermal energy of pressurized steam into mechanical work through a rotating output shaft. The distinction between 8406.82 and other subheadings is primarily based on the power capacity and the intended environment of use. If the turbine exceeds 40MW, it moves to 8406.81. If it is designed for marine use, it falls under 8406.10. Accurate classification requires a review of the manufacturer's technical data sheet to confirm the maximum continuous rating (MCR) and the intended application of the unit.
Products Included
- Industrial back-pressure steam turbines under 40MW

Common Misclassification
Small steam turbines are frequently confused with marine propulsion turbines classified under HS code 8406.10. While the mechanical principles are similar, the 8406.10 code is strictly for engines used to move vessels. Another common error is misclassifying units under 8406.81, which is reserved for larger turbines with an output exceeding 40MW. Importers must ensure the power rating is clearly documented to avoid these errors. Additionally, gas turbines are classified under 8411, and hydraulic turbines fall under 8410, both of which are distinct from steam-driven units.
