Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for marine auxiliary power generation
Auxiliary marine engines (non-propulsion) classify under other engines of diesel heading, not marine propulsion subheading.
If power exceeds 149.2 kW
Higher power marine propulsion engines fall into the next statistical break in the same marine propulsion heading.
If imported as complete marine propulsion machinery set with gearbox
Machinery with integral transmission components may classify as marine propulsion systems rather than bare engines.

Import Tips & Compliance
• Verify engine power rating with manufacturer's spec sheet; customs requires certification that output is measured at propeller shaft and within 111.9-149.2 kW range
• Include marine propulsion certification (e.g
• IMO compliance docs) and ensure engine is not configured for auxiliary/generator use to avoid reclassification
