4. Recommended Shipping Strategy (2026)
| Scenario | Recommended Method | Rationale |
|---|---|---|
| High-Volume Fleet Delivery (10+ units) | RO-RO via Qingdao Port | Fast turnaround, low handling risk, proven reliability |
| Remote Destinations (limited RO-RO access) | Flat Rack + Wax Encapsulation | Ensures structural integrity and traceability |
| Budget-Constrained Projects (non-critical timelines) | Not recommended: Bulk Cargo | High post-delivery rework cost offsets savings |
5. Pre-Shipment Checklist for HOWO Trailers
- Drain non-essential fluids (except engine oil, coolant)
- Apply wax corrosion protection (per Section 3)
- Secure all movable components (fifth wheel, landing gear)
- Deactivate battery; seal terminals
- Install moisture absorbers inside cab (if applicable)
- Document pre-shipment condition (photos, video log)
- Verify ISO container/RO-RO slot booking 14 days in advance
6. Conclusion
For reliable, large-scale export of Sinotruck HOWO truck trailers from China, RO-RO shipping remains the industry-preferred method, offering optimal protection, speed, and handling. Flat Rack containers are viable for niche routes but incur higher costs and exposure risks. Bulk cargo is discouraged due to unacceptably high corrosion and mechanical damage potential.
Mandatory implementation of industrial-grade wax spraying is critical to preserve chassis integrity during marine transit, reducing post-arrival rework and extending equipment service life in harsh operational environments.
