About HS Code 840681
This HS code covers large-scale steam and other vapor turbines with an output exceeding 40MW, specifically for non-marine propulsion applications. These are the workhorses of modern power generation, found in thermal, nuclear, and large-scale concentrated solar power plants. They are high-value, critical infrastructure components, traded globally between major energy equipment manufacturers and utility companies or independent power producers. The trade is characterized by long lead times, complex engineering, and significant project financing. Importers are typically countries expanding their power grids or replacing aging infrastructure, while exporters are global leaders in heavy industrial and power generation equipment.
Products Under This Code
Utility steam turbines, nuclear power plant turbines, combined cycle gas turbine (CCGT) steam turbines, industrial steam turbines (large), concentrated solar power (CSP) steam turbines
Real World Examples
Siemens Energy SGT5-8000H steam turbine, GE Power H-Class steam turbine, Mitsubishi Hitachi Power Systems (MHPS) J-Series steam turbine, Toshiba steam turbines
Common Misclassification
Differentiated from smaller turbines (840682) by their output capacity (>40MW) and from gas turbines (8411) by the working fluid (steam/vapor vs. combustion gases).
Products Classified Under 8406.81
Industry
This code belongs to the Electronics & Electrical Equipment industry.
Trade Overview
China, India, and the USA are major importers for new power plant construction, while Germany, Japan, and the USA are leading exporters of these large, high-output turbines.
