Final Discharge	West African, Middle Eastern, or Southeast Asian ports
Average Transit Time (China to Destination)	18–32 days
Truck Types Evaluated	Class 8 Tractors, Dump Trucks, Crane Carriers, Heavy Haulers

---

3. SHIPPING METHOD COMPARISON

Criteria	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Lo-Lo)	Flat Rack Container
Vehicle Readiness	Must be operational (drivable)	Can be non-operational	Any condition (inoperable accepted)
Loading Method	Driven onto vessel via ramps	Lifted by shipboard cranes	Secured on open-frame ISO flat racks
Protection Level	Moderate (exposed decks)	Low (stacked, no enclosure)	High (custom lashings, partial exposure)
Corrosion Risk	High (direct sea spray)	Very High (unprotected)	Moderate (controlled exposure)
Wax Spraying Efficacy	Critical – full undercarriage & chassis coverage required	Mandatory – all metal surfaces	Recommended – focus on joints, welds, suspension

Port Infrastructure Needs	RO-RO ramps at origin & destination	Heavy-lift cranes	Container spreaders, flat rack availability
Suitability for Fleet Export	High (large volumes, operational units)	Medium (budget option, higher risk)	High (premium protection, mixed conditions)

---

4. ANTI-CORROSION PROTECTION: WAX SPRAYING PROTOCOL

To ensure long-term asset integrity during oceanic transit, all trucks must undergo industrial-grade wax spraying prior to export. SEA LION International mandates the following procedure:

4.1 Wax Application Specifications

Parameter	Requirement
Wax Type	Solvent-based, hydrophobic, salt-displacing compound
Application Method	High-pressure spray (minimum 2,000 psi)
Coverage Areas	Full chassis rails, suspension components, brake lines, fuel tanks, wheel hubs, undercarriage
Coating Thickness	80–120 microns (measured via DFT gauge)
Drying Time	Minimum 4 hours at 20°C before transport
Reapplication	Required if pre-shipment storage exceeds 14 days in humid environments

4.2 Performance Validation

• Salt spray test compliant: ASTM B117 (480-hour exposure with <5% rust formation)
• Adhesion tested per ISO 2409 (Class 0–1 cross-hatch rating)
• Validated by third-party QA at loading port

Note: Wax protection is non-negotiable for RO-RO and Bulk Cargo due to high moisture exposure. Flat Rack units benefit from dual protection—wax + physical lashings.

---

5. RECOMMENDATIONS BY USE CASE

Fleet Profile	Recommended Method	Rationale
Large-volume, drivable fleets	RO-RO	Fast turnaround, cost-per-unit optimal; wax protection mitigates corrosion
Non-operational or damaged units	Flat Rack	Secure transport, full structural support, controlled exposure
Budget-constrained, short-sea routes	Bulk Cargo	Lowest cost, but high risk; only with full wax + desiccant sealing
High-value or specialized trucks	Flat Rack + Climate Monitoring	Maximum control, traceable conditions, minimal handling damage

---

6. OPERATIONAL CONSIDERATIONS

• Pre-shipment Inspection: All units require pre-embarkation checklist (fluid levels, battery disconnect, tire pressure, documentation).
• Lashing & Securing: RO-RO and Flat Rack units must comply with CTU (Cargo Transport Unit) Code for dynamic load resistance.
• Customs Compliance: US export declaration (EEI via AES) + Chinese transshipment permit required.
• Environmental Exposure: Ships spend 60–80% of voyage in high-humidity/salt-air zones; passive protection is essential.

---

7. CONCLUSION

For the export of used trucks from Grand Junction, CO via Chinese ports, RO-RO offers optimal efficiency for operational fleets, while Flat Rack provides superior protection for high-value or inoperable units. Bulk Cargo, though economical, poses significant corrosion and damage risks without rigorous wax sealing.

Wax-based anti-corrosion treatment is not optional—it is a structural preservation imperative across all shipping modes. SEA LION International enforces wax application as a standard clause in all used truck export contracts to ensure asset longevity and client satisfaction.
