- Thickness: 30–50 microns (uniform coating)
- Duration of Protection: Up to 6 months in maritime conditions
- Compliance: Meets ISO 9227 (salt spray testing) and ASTM D1748 (humidity resistance)
Benefits:
- Forms hydrophobic barrier against seawater ingress
- Reduces oxidation during 20–45 day transits
- Easily removable upon delivery using biodegradable degreasers
- Cost: ~$85–$120 per unit (one-time application)
Best Practice: Apply wax coating within 72 hours of final assembly, prior to inland transport to port.
4. Recommended Logistics Strategy
| Scenario | Recommended Method | Rationale |
|---|---|---|
| Operational Trucks (Ready-to-Use) | RO-RO | Fast turnaround, minimal handling, cost-effective for volume |
| Non-Operational or Modified Units | Flat Rack | Full structural protection, secure lashings, ideal for project cargo |
| Mixed Fleet Shipments | Hybrid: RO-RO + Flat Rack | Balance cost and protection; operational units via RO-RO, damaged or disassembled via Flat Rack |
Avoid: Bulk Cargo shipment for high-value construction and haulage vehicles.
5. Port of Loading & Compliance
- Primary POL: Qingdao Port, China (major RO-RO and container terminal)
- Export Documentation:
- Certificate of Origin (China Chamber of International Commerce)
- Bill of Lading (Sea Waybill for efficiency)
- Packing List (detailed for customs)
-
Vehicle Conformity Certificate (to destination standards)
-
Pre-Shipment Inspection (PSI): Mandatory for African, Middle Eastern, and CIS markets.
6. Conclusion
For efficient, secure export of Sinotruck HOWO Tractor Trucks from China:
– RO-RO is optimal for operational units requiring fast deployment.
