| Security & Vandalism Risk | Moderate | High | Low (sealed lashings, visibility) |
Note: All costs are FOB Qingdao or Lianyungang, China; destination assumed: Port of Lagos, Nigeria (West Africa route). Fuel, BAF, and CAF surcharges may apply.
3. Corrosion Protection: Wax Spraying Protocol
Seawater-induced corrosion is a critical risk during maritime transport, particularly for steel-intensive vehicles such as the Howo NX dump truck. SEA LION International recommends the following anti-corrosion wax spraying protocol as a mandatory pre-shipment procedure:
3.1 Wax Application Specifications
| Parameter | Requirement |
|---|---|
| Wax Type | Solvent-based, hydrophobic corrosion inhibitor (e.g., Woolwax™ or Dinitrol AV-27) |
| Application Method | High-pressure spray (200–300 psi) |
| Target Zones | Undercarriage, frame rails, suspension components, wheel hubs, exhaust system, battery compartment |
| Coating Thickness | 50–70 microns (verified via micrometer) |
| Drying Time | 4–6 hours (ambient 25°C, 60% RH) |
| Reapplication Threshold | Required if shipment delay exceeds 14 days |
3.2 Efficacy by Shipping Method
| Shipping Method | Wax Protection Efficacy | Rationale |
|---|---|---|
| RO-RO | Moderate | Continuous salt spray on open decks reduces wax longevity; partial wash-off likely |
| Bulk Cargo | Low | Direct exposure to sea conditions; no physical barrier |
| Flat Rack | High | Controlled environment; wax layer remains intact due to reduced turbulence and targeted coverage |
Recommendation: Wax treatment is non-negotiable for all export units. Flat Rack shipping maximizes wax effectiveness and should be prioritized for high-humidity or long-duration routes.
4. Operational Recommendations
| Priority | Recommendation |
|---|---|
| 1 | For operational trucks, RO-RO offers fastest turnaround but requires rigorous pre-shipment maintenance and immediate post-arrival decontamination. |
| 2 | For non-operational or high-value units, Flat Rack is optimal—provides structural security, corrosion control, and compatibility with wax protection. |
| 3 | Bulk Cargo is cost-effective but high-risk; only recommend for budget-constrained projects with robust refurbishment plans post-delivery. |
| 4 | Implement wax spraying + silica gel desiccant bags in cab and electronics enclosures to prevent internal condensation. |
| 5 | All units must undergo pre-shipment inspection (PSI) per ISO 14555 and include corrosion protection certification. |
5. Conclusion
For fleet managers and construction firms sourcing used Howo NX Dump Trucks from China, Flat Rack shipping combined with industrial-grade wax corrosion protection offers the highest integrity-to-cost ratio for long-haul maritime logistics. While RO-RO and Bulk Cargo present lower initial costs, their exposure risks compromise vehicle lifespan and increase post-import repair expenditures. SEA LION International endorses Flat Rack as the standard for corrosion-sensitive heavy equipment in tropical and coastal deployment zones.
