| Insurance Complexity | Low | High | Medium |
| Best Suited For | High-volume, time-sensitive shipments | Cost-sensitive, non-urgent bulk orders | High-value units, harsh climate routes |
4. Corrosion Protection: Wax Spraying System
Marine environments expose metal surfaces to salt-laden air and spray, accelerating corrosion—particularly on undercarriages, chassis frames, and suspension components of used tippers.
4.1 Wax Spraying Protocol
SEA LION International implements an industrial-grade anti-corrosion wax spraying system prior to shipment:
- Wax Type: Solvent-based, lanolin-infused, salt-displacing compound (ASTM B117 compliant)
- Application Method: High-pressure spray (15–20 bar), targeting:
- Chassis rails
- Suspension brackets
- Axle housings
- Wheel hubs and brake assemblies
- Underbody electrical conduits
- Film Thickness: 25–35 microns (dry)
- Coverage: Full undercarriage + wheel arches + cab mount points
- Curing Time: 4–6 hours (ambient 25°C)
4.2 Performance Benefits
| Benefit | Description |
|---|---|
| Saltwater Resistance | Wax forms hydrophobic barrier, preventing chloride ion penetration |
| Longevity | Protection effective for up to 60 days at sea (RH >85%, salinity 3.5%) |
| Non-Conductive | Prevents galvanic corrosion between dissimilar metals |
| Easy Post-Transit Removal | Biodegradable formula; removed with industrial degreaser or steam cleaning |
| Compatibility | Safe for rubber, plastics, and painted surfaces |
Note: Wax treatment is mandatory for all units shipped via RO-RO and Bulk Cargo; recommended for Flat Rack in tropical/salty climates.
5. Recommended Logistics Strategy by Region
| Destination Region | Preferred Method | Rationale |
|---|---|---|
| West Africa (Lagos, Tema) | RO-RO | Proximity to RoRo ports; high volume; reduced handling damage |
| Middle East (Dubai, Jeddah) | Flat Rack | High ambient salinity; need for maximum corrosion protection |
| Central Asia (via Iran) | Bulk Cargo | Cost-driven; inland routing; limited RoRo access |
| Southeast Asia | RO-RO or Flat Rack | Depends on port facilities; wax spraying essential due to humidity |
6. Compliance & Documentation
All shipments comply with:
– IMSBC Code (for Bulk)
– CTU (Cargo Transport Unit) Code (for Flat Rack)
– International Convention for Safety of Life at Sea (SOLAS) – Verified Gross Mass (VGM) for containers
– ISPS Code (security)
– Pre-shipment inspection (PSI) available upon request
7. Conclusion
For fleet managers and construction firms sourcing used Sinotruck Howo 371 tippers from China, RO-RO offers optimal balance of cost and speed for high-volume orders, while Flat Rack provides superior protection for high-risk maritime zones. Bulk Cargo remains a cost-effective option for non-critical timelines, though with increased risk of physical and environmental damage.
Wax spraying is a critical preventive measure—industrial application reduces post-import repair costs by up to 40% and extends operational lifespan in corrosive environments.
SEA LION International recommends a hybrid logistics model combining method selection based on destination, volume, and environmental exposure, with mandatory anti-corrosion treatment for all units.
