Import Tips

Verify engine power rating with manufacturer's spec sheet to confirm it falls within 149.2-223.8 kW range; misclassification to adjacent power bands is common

Include marine propulsion certification and EPA Tier 3 emissions documentation for U.S. customs clearance

Ensure gearbox or propeller shaft interfaces are declared separately if imported as an assembly to avoid set classification issues
