---

5. Recommended Logistics Strategy (2026)

Scenario	Recommended Method	Rationale
Large-scale fleet delivery	RO-RO + Wax Spray	Fast turnaround, reduced crane risk, scalable
Cost-sensitive bulk order	Bulk Cargo + Full Wax Encapsulation	Lowest cost; wax critical to offset high corrosion risk
High-value or prototype units	Flat Rack + Climate Wrap	Maximum control, visibility, and protection

---

6. Compliance & Documentation

All shipments must comply with:
– IMO CSS Code (Cargo Securing Manual)
– IMSBC Code (for bulk vessel stowage)
– China Export Inspection (CIQ) certification
– ISPM 15 (for wooden dunnage, if used)

Wax application must be documented with pre-shipment inspection reports and material safety data sheets (MSDS).

---

7. Conclusion

For hydraulic dump truck exports from China, RO-RO shipping with industrial wax protection offers the optimal balance of efficiency and equipment integrity for fleet-scale deliveries. While bulk cargo remains cost-effective, it demands rigorous anti-corrosion protocols. Flat rack is best reserved for specialized or low-volume consignments requiring maximum handling control.

SEA LION International advises integrating automated wax spraying systems at final assembly plants to ensure uniform protection and reduce export delays.
