Shipping & Logistics Solutions

Industrial Specification Report 2026
Prepared by: SEA LION International – Senior Engineering Division
Subject: Export Logistics Solutions for Used Trucks from China – Comparative Analysis of RO-RO, Bulk Cargo, and Flat Rack Shipping
Target Audience: Fleet Managers, Construction Equipment Procurement Officers

---

Executive Summary

This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack containerization—for the export of used trucks sourced from St. Louis, USA, and transshipped via Chinese export hubs. The objective is to provide fleet and construction logistics managers with a technical comparison to optimize cost, safety, and equipment integrity during ocean transit. Special emphasis is placed on corrosion protection via wax-based anti-seawater coatings.

---

1. Overview of Export Logistics Chain

Used trucks from St. Louis are typically consolidated at U.S. inland depots, transported to East Coast ports (e.g., Savannah, Charleston), shipped to transshipment hubs in China (e.g., Shanghai, Ningbo), and then exported to global destinations. SEA LION International manages the Chinese export leg, ensuring compliance with international maritime standards.

---

2. Comparative Shipping Methods

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Loose Stowage)	Flat Rack Container
Cargo Compatibility	Ideal for operational trucks; driven on/off vessel	Suitable for non-operational or disassembled units	Best for oversized, heavy, or non-driveable trucks
Loading Mechanism	Self-propelled or towed onto vessel decks	Craned or rolled into hold; secured with lashings	Secured on open-frame ISO flat rack; crane-loaded
Protection from Elements	Moderate (exposed to salt spray on deck)	Low (exposed in hold; condensation risk)	High (customizable tarping, wax protection applicable)
Corrosion Risk (Seawater)	High (deck exposure to salt-laden air/water)	Moderate (humidity; limited salt spray)	Low (with full wax coating + tarping)
Securing Method	Wheel chocks, lashing straps	Welded braces, timber blocking, chains	Twist locks, lashing rods, corner castings
Insurance & Claims Risk	Moderate (standard for RO-RO)	High (poor stowage increases damage risk)	Low (controlled environment, documented lashing)
Transit Time Efficiency	High (fast loading/unloading)	Medium (complex stowage planning)	Medium (requires crane ops at both ends)
Cost (USD per Unit)	$1,800 – $2,400	$1,500 – $2,000	$2,600 – $3,500
Port Infrastructure Needs	RO-RO ramps, clear approach lanes	Heavy-lift cranes, ballast management	Flat rack availability, crane access
Best For	Operational fleets, time-sensitive deliveries	Budget-sensitive, non-roadworthy units	High-value, custom, or oversized trucks

3. Corrosion Protection Protocol: Wax Spraying System

All used trucks exported via sea are vulnerable to saltwater-induced corrosion, particularly in humid marine environments. SEA LION International implements an industrial-grade wax spraying protection system as standard for all shipments, with enhanced application for Flat Rack and RO-RO units.

Wax Spraying Specifications:

• Material: Solvent-based, hydrophobic microcrystalline wax compound
• Application Method: High-pressure spray (12–15 bar), full undercarriage + chassis coverage
• Thickness: 50–70 μm dry film
• Coverage Areas:
• Frame rails
• Suspension components
• Wheel wells
• Exhaust system
• Brake lines and fuel tanks
• Performance: Resists saltwater penetration for up to 60 days at sea; complies with ISO 9223 corrosion classification (C3–C4 environments)

Note: Wax protection is mandatory for RO-RO and strongly recommended for Flat Rack units. Bulk cargo shipments receive partial undercarriage treatment due to accessibility limits.

---

4. Recommendations by Use Case

Client Profile	Recommended Method	Rationale
Large Fleet Managers (10+ units, operational)	RO-RO + Full Wax Spray	Fast turnaround, cost-effective, scalable; wax mitigates deck exposure risk
Construction Firms (Heavy Equipment, Non-Driveable)	Flat Rack	Maximum protection, secure lashing, compatibility with excavators or crane trucks
Budget-Conscious Buyers (Scrap or Rebuild Units)	Bulk Cargo with Partial Wax	Lowest cost; acceptable risk for non-priority assets

---

5. Compliance & Documentation

All shipments comply with:
– IMO CSS Code (Cargo Securing Manual)
– IMSBC Code (for bulk stowage)
– CTU Code (for containerized units)
– Phytosanitary & Customs Declarations (China Customs Export Filing)

Wax application logs and pre-shipment inspection reports are provided for audit and warranty validation.

---

6. Conclusion

For the export of used trucks from Chinese transshipment hubs, RO-RO offers optimal efficiency for driveable units, Flat Rack ensures superior protection for high-value or oversized assets, and Bulk Cargo serves as a cost-minimized option for non-operational units. Industrial wax spraying is a critical mitigation measure against seawater corrosion, especially in RO-RO and deck-exposed scenarios.

SEA LION International recommends integrating wax protection into all export workflows and selecting transport mode based on equipment condition, value, and delivery urgency.
