Parsons Reaction Marine Steam Turbine
A reaction-type steam turbine for ship propulsion, featuring partial admission blades for efficient steam expansion in maritime applications. Falls under HTS 8406.10.10.00 due to its design for marine steam propulsion.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as turbine parts like rotors or casings
Parts of marine steam turbines are separately provided for in 8406.90, not the complete turbine.
If for non-marine propulsion applications like industrial drives
Other steam turbines not for marine use fall under 8406.19, based on end-use application.
If coupled with electric generator for hybrid marine power
Generating sets with steam turbines may classify under Chapter 85 if sold as complete power units.

Import Tips & Compliance
• Obtain ABS or Lloyd's Register certification proving marine propulsion compliance to support tariff classification
• Declare precise power output and RPM ratings, as exceeding certain thresholds may trigger additional safety inspections
• Avoid mislabeling as parts; ensure import docs specify complete turbine assembly to prevent shifting to parts subheadings
