| Salt Spray Resistance | >1,000 hours (ASTM B117) |
| Drying Time | 2–4 hours (ambient) |
| Reversibility | Removable with industrial degreasers |
3.3 Application Workflow (Pre-Export)
- Surface Preparation: Degrease and dry all undercarriage surfaces.
- Masking: Protect sensors, exhaust outlets, and air intakes.
- Spraying: Apply even coat using robotic or manual spray rigs.
- Inspection: Verify coverage via UV tracer dye (if required).
- Documentation: Issue anti-corrosion certificate with batch ID.
Note: Wax treatment is mandatory for all HOWO units shipped via RO-RO or Bulk; recommended for Flat Rack under tropical routes.
4. Method-Specific Recommendations
4.1 RO-RO Shipping
- Best for: High-volume exports to RO-RO-equipped destinations (Middle East, Africa, Southeast Asia).
- Advantages: Fast turnaround, minimal handling damage.
- Risk Mitigation: Apply wax spray + install desiccant packs in cabin.
4.2 Bulk Cargo Shipping
- Best for: Cost-sensitive, low-priority shipments to remote bulk ports.
- Disadvantages: High moisture ingress in holds; lifting risks.
- Risk Mitigation: Full wax spray + plastic shrink-wrapping of cab and radiator.
4.3 Flat Rack Container
- Best for: Oversized HOWO variants (e.g., long-haul 8×4), or shipments to stringent regulatory markets (EU, North America).
- Advantages: Maximum protection, ISO-compliant tracking.
- Risk Mitigation: Wax spray + lashing report (DNV-GL compliant).
5. Operational Recommendations
| Priority | Recommended Method | Justification |
|---|---|---|
| Cost Efficiency | Bulk Cargo | Lowest base rate; suitable for non-critical timelines |
| Speed & Volume | RO-RO | Rapid port cycling; ideal for fleet replenishment |
| Equipment Integrity | Flat Rack | Optimal protection; preferred for high-value units |
| Corrosion-Sensitive Routes | All methods + Wax Spray | Critical for tropical/humid maritime corridors |
6. Conclusion
For fleet managers and construction firms procuring Sinotruk HOWO Tractor Trucks from China, RO-RO shipping offers the optimal balance of speed and cost for standard configurations, provided anti-corrosion wax spraying is implemented. Flat Rack containers are recommended for premium protection, especially in high-humidity or long-transit scenarios. Bulk cargo is viable only under strict cost constraints and with enhanced preservation protocols.
SEA LION International advises integrating industrial wax spraying as a standard pre-shipment procedure across all modal choices to ensure compliance with 24-month structural warranty requirements and reduce field maintenance costs.
