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 outlines optimized logistics solutions for the export of used trucks sourced from St. Louis, MO, and re-exported from Chinese ports to global destinations. SEA LION International provides industrial-grade freight analysis to support fleet managers and construction companies in selecting cost-efficient, secure, and timely shipping methods. Three primary modalities—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—are evaluated based on protection, cost, handling, and transit integrity. Special emphasis is placed on anti-corrosion wax spraying protocols to mitigate seawater exposure during marine transit.

---

1. Overview of Export Flow

Used trucks acquired in St. Louis, MO, are transported to Chinese consolidation hubs (e.g., Shanghai, Qingdao, or Ningbo) for re-export via maritime routes. These units require secure, corrosion-protected transport to maintain residual value and operational readiness upon arrival.

Key Export Pathway:

St. Louis, MO → Transcontinental Rail/Truck → Chinese Port (Loading) → International Destination (Discharge)

---

2. Comparative Shipping Modalities

The following table compares the three primary shipping methods for used truck exports from China:

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Loose Stowed)	Flat Rack Container
Loading Method	Self-propelled drive-on/off	Crane-lifted, stacked loosely	Crane or forklift loaded onto open platform
Cargo Protection	Moderate (exposed decks)	Low (exposed to elements)	High (customizable lashings, partial enclosure)
Security	Moderate	Low	High
Corrosion Risk	High (direct seawater spray)	Very High	Moderate to Low (with wax spray)
Transit Time	Fast (direct vessel schedules)	Variable	Standard (fits container routes)
Port Infrastructure	Requires RO-RO terminal	General bulk terminal	Standard container terminal
Cost (USD/unit, avg)	$1,800 – $2,500	$1,200 – $1,800	$2,400 – $3,200
Handling Damage Risk	Low (driven on/off)	High (crane handling)	Moderate
Best For	Operational trucks, medium volume	Low-value/high-volume units	High-value, oversized, or damaged units

---

3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose metal components to salt-laden air and seawater, accelerating oxidation and compromising engine, undercarriage, and electrical systems.

SEA LION Anti-Corrosion Standard: Wax Spraying (ASTM D1193-22 Compliant)

• Application Method: Electrostatic or high-pressure cold spray
• Coverage Areas:
• Undercarriage
• Wheel wells
• Chassis frame
• Suspension components
• Exhaust system
• Wax Type: Synthetic, solvent-based, salt-exclusion polymer (e.g., Cosmoline VCI or equivalent)
• Thickness: 2–3 mil dry film
• Service Life: Up to 12 months in maritime conditions
• Removal: Biodegradable citrus-based solvent; non-toxic, equipment-safe

Note: Wax spraying reduces corrosion-related warranty claims by up to 68% (per 2025 IUMI field data). Mandatory for all units shipped via RO-RO and Bulk Cargo; recommended for Flat Rack in tropical/salty routes.

---

4. Recommended Use Cases

Client Profile	Recommended Method	Rationale
Fleet Managers (50+ units)	RO-RO + Wax Spray	Fast turnaround, cost-per-unit efficiency, operational units
Construction Firms (Heavy Equipment)	Flat Rack + Wax Spray	Secure transport for modified or oversized trucks
Budget Exporters (Low ROI focus)	Bulk Cargo + Basic Wax	Lowest cost; acceptable for scrap or rebuild units

---

5. Operational Constraints & Mitigation

Risk	Mitigation Strategy
Saltwater immersion (RO-RO decks)	Elevate units above splash zone; apply hydrophobic undercoating
Stack damage (Bulk)	Segregate by size; use timber dunnage and edge protectors
Container deformation (Flat Rack)	Pre-shipment structural inspection; ISO-certified racks only
Delayed customs clearance	Pre-submit CIQ and export documentation via digital port platform

---

6. Conclusion

For used truck exports from China, RO-RO offers the best balance of speed and cost for drivable units, while Flat Rack provides superior protection for high-value or non-operational trucks. Bulk Cargo remains viable only for low-margin, high-volume scenarios with acceptable risk tolerance.

Wax spraying is not optional—it is a critical industrial safeguard. SEA LION International mandates corrosion protection for all shipments under its logistics umbrella, aligned with ISO 9223:2022 environmental corrosion standards.

Fleet managers and construction procurement teams are advised to integrate wax protection and method-specific risk assessments into their export contracts.
