About HS Code 840690

This HS code covers all parts of steam and other vapor turbines, encompassing components for both marine propulsion (840610) and non-marine applications (840681, 840682). This category is vital for the manufacturing, assembly, maintenance, and repair of these complex power-generating machines. The international trade involves a vast array of precision-engineered components, often made from specialized alloys to withstand extreme conditions. Importers include turbine manufacturers, power plant operators, shipyards, and MRO service providers globally, who rely on a robust supply chain for critical spares and upgrades. Exporters are typically advanced manufacturing nations with expertise in metallurgy and precision machining.

Products Under This Code

Turbine blades, rotors, diaphragms, casings, bearings (for turbines), seals (for turbines), control valves (for turbines), turbine shafts, nozzle blocks, labyrinth seals

Real World Examples

Siemens Energy turbine blades, GE Power rotor assemblies, Mitsubishi Heavy Industries turbine casings, SKF turbine bearings

Common Misclassification

Can be confused with parts of gas turbines (841190) or general machinery parts (8487) if not clearly identified as specific to steam or other vapor turbines. The material and design are often unique to steam applications.
