Subject: Logistics Solutions for Exporting ‘Thornton Used Trucks’ from China
Issuing Authority: SEA LION International – Senior Engineering Division
Date: 2026-04-05

Executive Summary

This report evaluates three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack shipping—for the export of used Thornton trucks from manufacturing and consolidation hubs in China. The analysis focuses on operational efficiency, cost structure, equipment integrity, and environmental protection, with emphasis on long-term corrosion prevention through wax-based anti-seawater treatments.

---

1. Introduction

SEA LION International provides industrial-grade logistics solutions for heavy equipment transport. With increasing demand for cost-effective used truck procurement from China, particularly among construction firms and fleet operators in Southeast Asia, Africa, and Latin America, optimized shipping methods are critical. This report compares RO-RO, Bulk Cargo, and Flat Rack shipping for the transport of Thornton used trucks, including protective measures against marine corrosion.

---

2. Transport Method Comparison

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo	Flat Rack Container
Suitability for Trucks	High – Designed for wheeled vehicles	Low – Not optimized for individual vehicle handling	High – Secure for non-operational or oversized units
Loading Mechanism	Driven on/off via ramps	Crane-lifted into hold	Crane-lifted; secured on open platform
Vehicle Condition Required	Operational (must be drivable)	Non-operational acceptable	Non-operational acceptable
Cargo Securing	Wheel chocks, tie-downs	Minimal; stowed in mass hold	Lashing chains, corner castings
Transit Time (China → Major Ports)	18–25 days	22–30 days	20–28 days
Port Infrastructure Dependency	High (RO-RO terminals required)	Moderate (bulk terminals)	Moderate (container terminals)
Damage Risk (Handling)	Low (if drivable)	High (contact during stowage)	Medium (exposure to elements)
Average Cost per Unit (USD)	$1,200–$1,600	$900–$1,300 (shared hold)	$1,800–$2,400
Scalability (Fleet Volume)	High (up to 50+ units/voyage)	Medium (depends on vessel mix)	Medium (limited by container availability)
Weather Exposure	Low (enclosed decks)	High (open holds, potential moisture)	High (fully exposed to salt spray)

---

3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose metal surfaces to chloride-laden air and saltwater immersion risks, accelerating oxidation and structural degradation. SEA LION International mandates the Wax-Based Anti-Corrosion Treatment (W-ACT) 2026 for all exported Thornton trucks.

3.1 Wax Spraying Specifications

Parameter	Specification
Application Method	High-pressure electrostatic spraying
Wax Composition	Microcrystalline wax + corrosion inhibitors (VCI)
Coating Thickness	25–35 µm (undercarriage, chassis, wheel hubs)
Coverage Areas	Frame rails, suspension components, brake lines, fuel tanks
Curing Time	4–6 hours (ambient 25°C)
Protection Duration	Up to 12 months in marine conditions
Compliance Standard	ISO 9223 (Corrosivity of Atmospheres), ASTM D130

3.2 Method-Specific Protection Requirements

Shipping Method	Wax Application Priority	Additional Measures
RO-RO	Medium – Enclosed transport reduces exposure	Interior desiccant packs; battery disconnect
Bulk Cargo	High – High moisture and contact risk	Full chassis encapsulation; VCI paper wrapping
Flat Rack	Critical – Fully exposed to salt spray	Double-coat wax; sealed electrical housings

---

4. Operational Recommendations

• RO-RO is recommended for operational fleets where drivability is confirmed. Offers fastest loading, lowest handling risk, and moderate cost.
• Bulk Cargo is not advised for high-value truck shipments due to uncontrolled stowage and elevated damage/corrosion risk. Suitable only for scrap or non-revenue units.
• Flat Rack is optimal for non-operational or oversized Thornton models requiring disassembly. Justified for specialty units despite higher cost.

Note: All units must undergo pre-shipment wax protection. SEA LION-certified facilities in Shanghai, Guangzhou, and Qingdao offer on-site W-ACT 2026 treatment.

---

5. Conclusion

For fleet managers and construction companies sourcing Thornton used trucks from China, RO-RO shipping with full wax corrosion protection represents the optimal balance of cost, safety, and equipment integrity. Flat Rack is a viable alternative for non-drivable units, provided enhanced protective protocols are implemented. Bulk cargo transport is discouraged for revenue-grade equipment.

SEA LION International continues to lead in industrial logistics engineering, ensuring asset longevity through climate-adaptive shipping and preservation technologies.
