| Film Thickness | 25–40 μm (dry) |
| Salt Spray Resistance | 720+ hours (ASTM B117) |
| Reversibility | Biodegradable remover available (non-toxic) |
| Validity | 6 months (marine exposure) |
Note: Wax protection is mandatory for all shipping modes. RO-RO and Bulk Cargo require full undercarriage coverage due to direct exposure. Flat Rack units benefit from dual protection—wax + optional polywrap encapsulation.
4. Risk & Mitigation Analysis
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Seawater Splash | High (lower decks) | Very High | Medium (elevated) |
| Deck Drainage Issues | Moderate | High | Low |
| Lashing Failure | Low (integrated) | High | Medium (ISO standards) |
| Theft/Vandalism | Low (secured vessel) | Medium | Low (container seal) |
| Delay at Port | Low | Medium (crane queues) | Medium (customs hold) |
5. Recommended Strategy by Use Case
| Client Profile | Recommended Method | Rationale |
|---|---|---|
| Large construction fleet (100+ units) | RO-RO | Fast turnaround, cost-effective for operational units, proven in ASEAN/MENA |
| Budget-constrained buyer | Bulk Cargo (with wax+) | Lowest cost; requires post-arrival reconditioning and inspection |
| Mountainous terrain delivery | Flat Rack + CKD kits | Enables disassembly; avoids size restrictions at inland ports |
| High-humidity destinations (e.g., West Africa, Pacific Islands) | Flat Rack + wax + tarpaulin | Maximum environmental shielding |
6. Compliance & Documentation
All shipments comply with:
– IMO CSS Code (Cargo Securing Manual)
– IMSBC Code (for Bulk vessels)
– CTU Code (Containerized Transport Units)
– CIQ Export Inspection (China Entry-Exit Inspection and Quarantine)
– Bill of Lading with condition report pre-loading
Conclusion
For Sinotruck HOWO exports, RO-RO offers optimal balance of cost and speed for operational units destined to RO-RO-capable ports. Flat Rack containers provide superior protection for high-value or oversized configurations, especially in corrosive climates. Bulk Cargo remains a cost-driven option, but demands rigorous post-arrival QA and wax protection to mitigate corrosion risk.
SEA LION International implements standardized wax spraying across all shipments, ensuring compliance with industrial durability standards and minimizing warranty exposure due to transit-induced corrosion.
