| Best For | Not recommended | Low-cost, high-volume, non-critical | High-value, corrosion-sensitive units |
3. Corrosion Protection: Wax Spraying System
Used truck engines are highly susceptible to marine atmospheric corrosion due to chloride ions and high humidity during ocean transport. SEA LION International recommends industrial-grade wax-based anti-corrosion treatment as a standard protective measure.
Wax Spraying Protocol (Per ISO 20743 & ASTM D1748)
| Step | Procedure | Specification |
|---|---|---|
| 1 | Surface Cleaning | Degrease with alkaline solvent; dry at 40°C |
| 2 | Wax Application | Spray-applied synthetic hydrophobic wax (e.g., VCI-enriched microcrystalline wax) |
| 3 | Coating Thickness | 20–30 µm uniform layer |
| 4 | Drying & Curing | 2 hours at ambient temperature |
| 5 | Secondary Protection (Optional) | Shrink-wrapping + desiccant packs |
Benefits of Wax Protection:
- Forms hydrophobic barrier against saltwater mist
- Inhibits electrochemical corrosion on ferrous components
- Removable via standard degreasing at destination
- Compatible with all shipping methods, especially critical for Bulk and RO-RO
Note: Wax treatment increases per-unit cost by $18–$25, but reduces field failure and rework by up to 70% (based on 2025 SEA LION field data).
4. Recommended Shipping Strategy
| Scenario | Recommended Method | Rationale |
|---|---|---|
| High-value engines, corrosion-sensitive markets (e.g., EU, GCC) | Flat Rack + Wax Spray | Maximum protection, traceability, security |
| High-volume, cost-sensitive, inland destinations | Bulk Cargo + Wax + Desiccant | Lower cost; wax mitigates high corrosion risk |
| Engines with rolling chassis (rare) | RO-RO | Only if engine is part of drivable unit |
| Mixed cargo (engines + parts) | Flat Rack (shared load) | Efficient space utilization, secure |
5. Conclusion
For the export of used truck engines from China:
– Flat Rack shipping with wax-based anti-corrosion treatment is the optimal solution for preserving engine integrity and ensuring compliance with international reconditioning standards.
– Bulk Cargo may be viable for budget-driven operations, but only when combined with rigorous wax protection and moisture control.
– RO-RO is not recommended for standalone engine shipments due to exposure and handling inefficiencies.
SEA LION International advises fleet managers and construction firms to prioritize cargo lifecycle protection over initial freight savings. Implementing wax spraying protocols reduces long-term maintenance costs and enhances resale value in secondary markets.
