| Budget-limited, high-tolerance risk | Bulk Cargo (not advised) | Only if units are scrap-grade; high corrosion and damage risk |
SEA LION Recommendation: For Monroe used trucks, RO-RO with wax spraying offers optimal balance of cost, speed, and asset preservation. Flat Rack is advised for non-drivable or customized units.
6. Operational Workflow (RO-RO with Wax Protection)
- Pre-shipment Inspection – Verify drivability, fluid levels, battery status
- Wax Spraying – Full undercarriage and chassis treatment at approved depot
- Dehumidification – Interior cabin drying to prevent mold
- Loading – Drive onto RO-RO vessel; secure with wheel chocks and straps
- Transit Monitoring – GPS-tracked vessels with climate logging
- Destination Unloading – Drive-off at port, immediate post-arrival washdown advised
7. Conclusion
Exporting Monroe used trucks from China demands a logistics strategy that balances economic efficiency with long-term asset integrity. RO-RO shipping, enhanced with industrial wax corrosion protection, is the preferred solution for operational fleets. Flat Rack containers serve as a secure alternative for non-drivable units. Bulk Cargo is discouraged due to high risk of structural and cosmetic degradation.
SEA LION International advises all fleet managers and construction firms to integrate wax-based protection into their export protocols to ensure vehicle longevity and compliance with international reconditioning standards.
