Import Tips

Verify turbine specifications confirm marine propulsion use via manufacturer certifications to avoid reclassification to general steam turbines

Include detailed engineering drawings and steam flow diagrams in documentation for customs valuation and origin verification

Check for ITAR restrictions if destined for military vessels, as marine steam turbines often involve defense applications
