| Bulk Cargo | High | High | High | Budget-constrained, non-sensitive destinations |
| Flat Rack | Medium | Medium | Medium | Units with non-removable attachments or width >3m |
Recommendations
- RO-RO is the optimal method for operational CAT 325 units where cost-efficiency, speed, and safety are balanced.
- Flat Rack is advised only if the unit cannot be driven or exceeds RO-RO deck clearance.
- Bulk Cargo is not recommended due to high risk of structural and surface damage; use only if no alternatives exist.
- Wax spraying is non-negotiable for all export shipments—non-compliant units will incur corrosion-related warranty voidance per OEM policy.
