4. Recommendation by Use Case

Scenario	Recommended Method	Rationale
Export of 20+ operational NH trucks	RO-RO	Fast turnaround, low handling damage, cost per unit optimized
Single non-running unit, budget-limited	Bulk Cargo	Lowest cost; acceptable if wax protection and insurance are reinforced
Modified or high-value NH units	Flat Rack	Maximum control, protection, and traceability

---

5. Operational Workflow (SEA LION Standard)

1. Pre-shipment Inspection – Verified operational status, fluid levels, tire pressure.
2. Cleaning & Degreasing – High-pressure wash, removal of mud/salt residues.
3. Wax Spraying – Full undercarriage treatment per Section 3.
4. Loading & Securing – Method-specific lashing (RO-RO chocks, Flat Rack twist locks).
5. Documentation – Bill of Lading, Certificate of Conformity, Corrosion Protection Report.
6. Transit Monitoring – GPS tracking (Flat Rack), humidity logs (Bulk/RO-RO holds).

---

6. Conclusion

For the export of used NH-series trucks from China, RO-RO shipping offers the optimal balance of speed, safety, and economy for operational units. Flat Rack is superior for high-value or modified configurations requiring maximum protection. Bulk Cargo, while cost-attractive, carries elevated risk and is recommended only with stringent wax protection and insurance coverage.

SEA LION International enforces wax spraying as a non-negotiable step in all export operations to ensure asset integrity across all shipping methods.
