HS-4 · Heading

8406Turbines; steam and other vapour turbines

Chapter 84: Nuclear reactors, boilers, machinery

Plain-language overview

Use HS-4 8406 when importing or exporting turbines, particularly steam and other vapor turbines. For example, if you’re shipping a steam turbine designed for marine propulsion, this is the appropriate code to use.

When deciding between the subheadings, consider the intended use of the turbine. HS-6 840610 is specifically for turbines used in marine propulsion, while HS-6 840681 and HS-6 840682 cover turbines for other applications, with the former exceeding 40MW output and the latter not exceeding that threshold.

If your shipment involves parts of turbines, you would use HS-6 840690. This line is distinct from the turbine codes and is specifically for components rather than complete units, so ensure you classify correctly based on what you are importing or exporting.
