4. Method-Specific Recommendations

4.1 RO-RO Shipping

• Advantages: Fast loading/unloading, minimal handling damage, ideal for operational vehicles.
• Constraints: Limited to ports with RO-RO infrastructure; higher cost than bulk.
• Use Case: Preferred for fleet deliveries to Middle East, Africa, and Southeast Asia with established RO-RO terminals.

4.2 Bulk Cargo Shipping

• Advantages: Lowest cost per unit; suitable for non-operational or stripped units.
• Constraints: High risk of impact damage; complex stowage planning; extended port turnaround.
• Use Case: Applicable for reconstruction markets or where cost is primary; not recommended for finished HOWO heads without structural cradles.

4.3 Flat Rack Container

• Advantages: Maximum control over securing and weather protection; ISPM-compliant; integrates with multimodal logistics.
• Constraints: Higher cost; limited availability of flat racks in off-peak seasons.
• Use Case: Recommended for high-value contracts, remote destinations, or mixed cargo shipments.

---

5. Compliance & Standards

All shipments comply with:
– IMDG Code (for fuel tank residuals)
– CSS Code (Cargo Securing Manual per unit)
– ISPM 15 (for wooden dunnage, if used)
– RoHS & REACH (wax formulation)

---

6. Conclusion

For fleet managers and construction logistics operators sourcing HOWO Truck Heads from China, RO-RO shipping offers the optimal balance of cost, speed, and integrity for standard deliveries. Flat Rack containers are advised for premium or mixed-load contracts requiring maximum protection. Bulk Cargo remains a niche option for cost-driven, non-critical deployments.

Wax-based anti-corrosion treatment is non-negotiable for all sea-exported units and must be applied at origin under ISO 9001-certified conditions.
