| Best For | High-volume fleets, operable trucks | Non-operational units, scrap/repair | High-value or sensitive-condition units |
3. Corrosion Risk Assessment & Mitigation
Environmental Exposure During Transit
- Average humidity: 75–95%
- Saltwater aerosol concentration: High in Pacific shipping lanes
- Exposure duration: 18–30 days
Used trucks, especially those with residual moisture or existing surface imperfections, are highly susceptible to marine-induced corrosion during ocean transport. This is particularly critical for undercarriages, brake systems, and exposed metal joints.
Recommended Protection: Wax-Based Anti-Corrosion Spray
SEA LION International mandates the application of industrial-grade wax emulsion spray as a preventive measure prior to shipment. This treatment is applied to all exposed metal surfaces, including:
- Chassis frames
- Suspension components
- Wheel hubs and brake assemblies
- Exhaust manifolds and underbody panels
Wax Spray Specifications (Per ASTM D130/D665 Compliance)
| Property | Specification |
|---|---|
| Base Composition | Microcrystalline wax + corrosion inhibitors (VCI) |
| Thickness (Dry Film) | 25–35 µm |
| Salt Spray Resistance (ASTM B117) | >500 hours |
| Application Method | High-pressure spray (150–200 psi) |
| Drying Time | 30–45 minutes (ambient 25°C) |
| Removal | Biodegradable solvent or steam wash |
Note: Wax treatment adds $85–$120 per unit but reduces post-arrival reconditioning costs by up to 40%.
4. Method-Specific Recommendations
RO-RO – Preferred for Operational Fleets
- Ideal for 5+ truck shipments
- Fast turnaround at origin and destination
- Requires pre-shipment wash and wax to prevent salt buildup in crevices
Bulk Cargo – Cost-Effective for Non-Operational Units
- Suitable for trucks requiring refurbishment upon arrival
- High corrosion risk; mandatory wax treatment and sealed cabs advised
- Not recommended for late-model or low-mileage units
Flat Rack – Maximum Protection & Flexibility
- Optimal for oversized or custom-configured trucks (e.g., crane carriers, mixers)
- Allows full undercarriage wax application and tarpaulin covering
- Higher cost justified for premium resale or mission-critical equipment
5. Operational Workflow (China Export to Portland, OR)
- Pre-shipment Inspection & Cleaning – Remove dirt, grease, and moisture
- Wax Spraying & Drying – Full underbody and exposed metal coverage
- Documentation & Customs Clearance – Chinese export compliance + U.S. EPA/DOT import
- Loading & Securing – Method-dependent stowage and lashing
- Ocean Transit – Real-time GPS tracking and humidity monitoring
- Portland Discharge & Inspection – Post-arrival corrosion check and cleaning
6. Conclusion & Strategic Recommendation
For fleet managers and construction companies sourcing used trucks from China, RO-RO shipping with industrial wax protection offers the optimal balance of cost, speed, and asset preservation. While Flat Rack provides superior environmental shielding, its cost is justified only for high-value or specialized units. Bulk cargo remains viable for repair-bound fleets but requires stringent corrosion controls.
SEA LION International recommends:
✅ Standardize wax spraying across all export shipments
✅ Use RO-RO for operable trucks (≥80% functional condition)
✅ Reserve Flat Rack for non-standard or premium-condition units
Implementation of these protocols ensures compliance with industrial durability standards and maximizes residual equipment value upon arrival in the Portland market.
