- Destination: NH (North Harbor) and equivalent deep-water terminals
- Cargo Type: Used commercial trucks (5–40 tons GVW)
- Average Shipment Volume: 10–50 units per consignment
- Critical Risk: Seawater-induced corrosion during transit (7–28 days, depending on route)
2. Comparative Analysis: RO-RO vs. Bulk Cargo vs. Flat Rack
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Loose Stowage) | Flat Rack Container |
|---|---|---|---|
| Loading Method | Driven on/off vessel via stern ramp | Craned or forklift-loaded into hold | Secured on open-frame ISO flat racks |
| Cargo Compatibility | Operational trucks only (must self-propel) | All truck types, including non-operational | All truck types, including oversized units |
| Stowage Density | High (efficient vertical stacking) | Medium (limited by crane access & hold geometry) | Low to Medium (requires lateral spacing) |
| Transit Time | 7–14 days (direct routes) | 10–21 days (subject to port congestion) | 12–28 days (container scheduling delays possible) |
| Handling Damage Risk | Low (minimal lifting) | High (multiple crane lifts, potential impact) | Medium (secure lashing reduces risk) |
| Corrosion Exposure | High (open decks, direct salt spray) | Medium (partially enclosed, humidity buildup) | High (fully exposed to marine atmosphere) |
| Average Cost per Unit (USD) | $1,100–$1,500 | $900–$1,300 | $1,600–$2,200 |
| Insurance Premium | Moderate | High (due to handling risk) | Moderate to High |
| Best For | Fleet transfers of operational units | Budget-sensitive, mixed-condition consignments | Oversized, non-standard, or disassembled trucks |
3. Corrosion Protection: Wax Spraying Protocol
Marine atmospheric conditions during transit induce accelerated corrosion on exposed ferrous components (chassis rails, suspension, undercarriage). SEA LION International mandates a standardized anti-corrosion wax spray treatment for all exported used trucks.
Wax Spraying Specifications:

| Film Thickness | 25–50 µm (measured via magnetic gauge) |
| Drying Time | 2–4 hours (ambient 25°C) |
| Protection Duration | Up to 6 months (marine exposure) |
| Reapplication Requirement | Prior to resale if storage > 90 days post-discharge |
Note: Wax treatment reduces post-transit rust claims by up to 78% (based on 2025 SEA LION claims data across 1,200 units).
4. Recommended Shipping Strategy by Use Case
| Use Case | Recommended Method | Rationale |
|---|---|---|
| Fleet Renewal – Operational Units | RO-RO | Fast turnaround, low handling risk, cost-effective for drivable assets |
| Budget Export – Mixed Condition Trucks | Bulk Cargo | Lower freight cost; suitable for non-running units requiring post-arrival refurbishment |
| Oversized/Modified Trucks (e.g., crane carriers) | Flat Rack | Accommodates width/height beyond container limits; full structural visibility |
5. Operational Recommendations
- Pre-shipment Inspection: Conduct SAE J2534-compliant diagnostics and fluid checks prior to export.
- Fuel & Fluid Management: Reduce diesel to ≤ 1/4 tank; disable battery; drain condensation traps.
- Wax Application Timing: Apply within 48 hours of final wash; verify coverage via UV tracer dye.
- Lashing Compliance: Adhere to CSC and ISO 1496 standards for securing loads on flat racks.
- Documentation: Provide EPA-compliant export declarations, title transfers, and corrosion treatment certificates.
6. Conclusion
For fleet managers and construction firms sourcing used trucks from China, RO-RO shipping offers the optimal balance of speed, safety, and cost for operational units. Bulk Cargo remains viable for non-running assets where cost is primary. Flat Rack is indispensable for non-standard configurations. In all cases, industrial-grade wax spraying is non-negotiable for preserving metal integrity during marine transit.
