Prepared by: SEA LION International
Subject: Export Logistics Solutions for Used Trucks from China – OKC Market
Target Audience: Fleet Managers & Construction Companies
1. Executive Summary
SEA LION International presents a technical evaluation of marine transport options for exporting used trucks from major Chinese ports (e.g., Shanghai, Guangzhou, Qingdao) to global markets, with focus on cost-efficiency, cargo integrity, and operational reliability. This report compares three primary shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack containerized transport—for used trucks marketed under the “used trucks for sale OKC” trade stream.
Key considerations include transit duration, structural protection, corrosion mitigation, and compatibility with heavy-duty fleet logistics. A standardized wax-based anti-corrosion treatment is recommended for all export units to ensure longevity during sea transit.
2. Shipping Method Comparison
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Loose Stowage) | Flat Rack Container |
|---|---|---|---|
| Loading Mechanism | Self-driven onto vessel | Craned/lifted into hold | Craned onto open-frame container |
| Cargo Compatibility | Operational trucks only | All truck types (incl. non-runners) | All truck types (incl. oversized) |
| Protection Level | Moderate (exposed decks) | Low (stacked, minimal cover) | High (custom lashings, partial enclosure) |
| Corrosion Risk | High (direct salt spray) | Very High (confined humid hold) | Moderate (exposed sides) |
| Transit Time (China → US Gulf) | 28–35 days | 30–40 days | 32–38 days |
| Port Infrastructure | Requires RO-RO terminal | Standard bulk terminal | Standard container terminal |
| Average Cost per Unit (USD) | $1,800 – $2,400 | $1,500 – $2,000 | $2,600 – $3,500 |
| Insurance Complexity | Low | Medium | High |
| Security & Theft Risk | Moderate | High | Low |
| Best For | Operational fleets, high volume | Budget-sensitive, non-running units | Oversized, custom, or high-value units |
3. Corrosion Protection: Wax Spraying Protocol
Seawater exposure during marine transit poses a critical threat to undercarriage components, electrical systems, and structural weld points on used trucks. SEA LION International mandates the application of marine-grade wax-based anti-corrosion spray for all export-bound units.
3.1 Wax Spraying Specifications
| Parameter | Specification |
|---|---|
| Product Type | Solvent-based, hydrophobic polymer wax |
| Application Method | High-pressure spray (minimum 25 psi) |
| Coverage Areas | Frame rails, suspension, fuel tanks, brake lines, wheel hubs |
| Film Thickness | 30–50 μm (uniform coat) |
| Salt Spray Resistance | ASTM B117 compliant (≥500 hrs) |
| Reapplication Requirement | Not required for single-transit export |
| Drying Time | 2–4 hours (ambient 25°C) |
3.2 Benefits
- Forms a water-displacing barrier on ferrous and non-ferrous metals
- Reduces chloride ion penetration by >90%
- Preserves resale value and mechanical integrity
- Complies with ISO 9227 environmental exposure standards
4. Method-Specific Recommendations
4.1 RO-RO Shipping
- Advantages: Fast loading/unloading, low handling damage, ideal for operational fleets.
- Limitations: Limited to drivable units; higher exposure to salt-laden air.
- Mitigation: Pre-shipment wax spray + wheel well sealing recommended.
4.2 Bulk Cargo
- Advantages: Lowest cost; accommodates non-functional units.
- Limitations: High risk of moisture accumulation; no structural containment.
- Mitigation: Wax spray + desiccant bags in cab and engine compartment advised.
4.3 Flat Rack Containers
- Advantages: Full structural control; suitable for wide loads (e.g., dump trucks, cranes).
- Limitations: Higher cost; requires specialized lifting.
- Mitigation: Wax spray + side tarpaulin covering during transit recommended.
5. Operational Workflow (China Export)
- Pre-shipment Inspection – Verify drivability, fuel level, battery status
- Corrosion Protection – Full undercarriage wax spray application
- Documentation – Title clearance, export customs (CIQ), bill of lading
- Port Handling – Transport to terminal; method-specific loading
- Marine Transit – Vessel tracking via AIS; condition monitoring
- Destination – Customs clearance, post-transit inspection, delivery
6. Conclusion
For fleet managers and construction firms sourcing used trucks from China, shipping method selection must balance cost, cargo condition, and long-term asset preservation.
- RO-RO is optimal for drivable fleets requiring rapid deployment.
- Bulk Cargo suits budget-driven procurement of repairable units.
- Flat Rack is superior for oversized or high-value equipment.
Universal Recommendation: All units must undergo industrial wax spraying prior to shipment to mitigate seawater corrosion and ensure compliance with international durability benchmarks.
