Westinghouse Geared Marine Steam Turbine
Geared steam turbine system for merchant ships, reducing high turbine speeds to propeller RPM via reduction gears for propulsion. HTS 8406.10.10.00 applies as it's a complete steam turbine for marine use.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported primarily as the reduction gear mechanism
Clutches and gears for marine propulsion have separate provisions in 8483, separate from turbine itself.
If for direct-drive stationary turbines
Other vapor turbines like those for power plants use different subheadings based on propulsion vs stationary.
If pre-installed in a complete tanker vessel
Vessels with installed turbines classify as ships under Chapter 89, not separate machinery.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Include gearbox integration details in invoices, as bundled components must align with marine propulsion tariff text
• Prepare for vibration and noise compliance testing under IMO regulations during import clearance
• Use precise HS descriptions matching 'steam turbines for marine propulsion' to prevent shifts to broader categories
