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
