Target Audience: Fleet Managers & Construction Companies
Executive Summary
This report evaluates industrial-grade logistics methodologies for the export of used trucks from manufacturing and consolidation hubs in China to end-market destinations in Oklahoma City, OK, USA. As demand rises for cost-effective, pre-owned heavy-duty vehicles in North American construction and logistics sectors, SEA LION International provides a comparative analysis of three primary maritime shipping modalities: Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack (Flat Rack Containerized) transport. Each method is assessed for suitability, cost-efficiency, transit reliability, and corrosion protection—specifically addressing the critical need for anti-seawater corrosion treatment via industrial wax spraying.
1. Export Logistics Overview
Used trucks exported from China are typically consolidated at major ports such as Shanghai, Qingdao, and Guangzhou. Final inland delivery to Oklahoma City is coordinated via U.S. Gulf Coast ports (e.g., Houston, TX) with overland drayage via Class I rail or heavy-haul trucking.
Key Export Flow:
China Port → Trans-Pacific Vessel → U.S. Gulf Port → Inland Rail/Truck → Oklahoma City, OK
2. Comparative Shipping Modalities
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Loose Stowed) | Flat Rack (40′ HC Flat) |
|---|---|---|---|
| Loading Mechanism | Self-driven onto vessel decks | Craned/stowed in hold | Craned onto open-frame containers |
| Cargo Protection | Moderate (exposed decks) | Low (stacked, no enclosure) | High (secured, weather-resistant) |
| Vehicle Integrity Risk | Low (if properly secured) | High (vibration, shifting) | Very Low (fully restrained) |
| Transit Time (China → Houston) | 28–35 days | 30–40 days | 28–33 days |
| Port Handling Speed | Fast (drive-on/drive-off) | Slow (crane-dependent) | Moderate (requires rigging) |
| Cost per Unit (USD) | $1,800 – $2,400 | $1,500 – $2,000 | $2,600 – $3,400 |
| Insurance Complexity | Standard | High (damage risk) | Standard to High (premium coverage) |

| Drying Time | 2–4 hours (ambient 25°C) |
| Performance Life | Up to 18 months in marine environments |
| Compliance | ASTM D610, ISO 9227 (salt spray tested) |
Note: Wax treatment is mandatory for all shipments via RO-RO and Bulk Cargo due to direct seawater aerosol exposure. Flat Rack units benefit from added protection but still require treatment for full asset preservation.
4. Risk & Mitigation Analysis
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Saltwater Corrosion | High (exposed) | Very High | Moderate |
| Mechanical Damage | Low | High | Very Low |
| Weather Exposure | High | Very High | Moderate |
| Theft/Vandalism | Low | Moderate | Low |
| Delay at Port | Low | High | Moderate |
| Recommended Mitigation | Wax spray + GPS tracking | Wax spray + full insurance | Wax spray + lashing certification |
5. Recommended Solution by Use Case
| Customer Profile | Recommended Method | Rationale |
|---|---|---|
| Large Fleet Procurement (10+ trucks, operable) | RO-RO | Cost-effective, rapid loading, wax-protected units maintain resale value |
| Budget-Conscious Buyers (non-running units) | Bulk Cargo | Lowest cost; requires full refurbishment post-arrival |
| High-Value or Oversized Trucks (e.g., crane trucks, lowboys) | Flat Rack | Maximum protection, secure transport, ideal for non-driveable units |
6. Conclusion & Recommendations
For fleet managers and construction firms sourcing used trucks from China, RO-RO shipping with full wax corrosion protection offers the optimal balance of cost, speed, and asset integrity for operable units. Flat Rack is advised for specialized or high-value equipment requiring maximum structural safeguarding. Bulk Cargo remains a niche option for non-operational units where upfront cost is the primary constraint.
SEA LION International enforces mandatory wax spraying across all export shipments to ensure compliance with international durability standards and to preserve residual asset value upon arrival in Oklahoma City, OK.
All shipments are tracked via IoT-enabled GPS tags and accompanied by corrosion inspection reports pre- and post-transit.
