| 3 | Bulk Cargo | Not Recommended – High risk of corrosion, mechanical damage, and insurance claims. |
5. Operational Recommendations
- Pre-Shipment Preparation:
- Drain and seal all fluid reservoirs if non-operational.
- Install desiccant packs in cab and engine compartment.
-
Apply wax spray 72 hours prior to vessel loading.
-
Documentation:
- Provide wax application certificate.
- Include detailed lashing plan (for Flat Rack).
-
Submit vehicle conformity and export compliance forms.
-
Port of Loading:
- Use designated RO-RO terminals: Qingdao, Shanghai, Nansha.
-
Avoid transshipment hubs with high congestion.
-
Monitoring:
- Equip shipments with IoT humidity/tilt sensors (optional for high-value consignments).
6. Conclusion
RO-RO shipping remains the industry-preferred method for exporting Head Tractor Trucks from China, offering superior protection, faster turnaround, and reduced logistical complexity. When combined with standardized wax spraying protocols, RO-RO ensures fleet integrity upon arrival. Flat Rack serves as a viable backup for non-standard configurations. Bulk Cargo is discouraged due to unacceptable risk exposure.
SEA LION International advises integrating wax protection into the standard export workflow to mitigate long-term corrosion liabilities and ensure operational readiness upon delivery.
