• Verify engine power rating with manufacturer specs to confirm it does not exceed 111.9 kW for this subheading; provide test data if requested by customs

• Include marine propulsion certification and EPA Tier 3 emissions documentation to avoid reclassification or delays

• Declare as 'new' or 'used' accurately; used engines may require additional condition reports to prevent undervaluation penalties
