Note: Bulk Cargo presents lowest upfront cost but highest risk of post-arrival rework or warranty claims due to corrosion or damage.

---

6. Recommendations

1. For Budget-Conscious, High-Volume Fleets:
2. Use Bulk Cargo with mandatory wax spraying and shrink-wrapping.

3. Accept higher post-inspection labor for re-lubrication and cleaning.

4. For Balanced Cost & Reliability:

5. RO-RO is optimal for self-propelled units with on-site commissioning teams.

6. Combine with wax treatment and deck placement below main deck when possible.

7. For Premium Protection & Traceability:

8. Flat Rack is recommended for units destined to humid/tropical regions.
9. Enables GPS tracking, faster customs clearance, and minimal post-arrival maintenance.

---

7. Conclusion

While Bulk Cargo offers the lowest base freight cost for exporting low-cost excavators from China, its exposure risks necessitate robust anti-corrosion protocols. RO-RO provides a balanced solution for operational fleets, whereas Flat Rack ensures maximum integrity at a premium. Mandatory wax-based corrosion protection is non-negotiable across all methods to preserve equipment lifespan and reduce field failure rates.

SEA LION International recommends integrated logistics packages combining method-optimized shipping with factory-applied wax sealing to ensure cost-effective, durable delivery of construction equipment.
