---

3. Corrosion Mitigation: Wax Spraying Protection

3.1 Overview

Seawater exposure during maritime transport poses a significant risk to undercarriages, chassis frames, and engine compartments of used trucks. Wax-based anti-corrosion spraying is a proven industrial solution to inhibit salt-induced oxidation.

3.2 Application Protocol

• Pre-Treatment: Degrease and dry all metal surfaces, especially frame rails, suspension components, and wheel wells.
• Spray Application: Use high-pressure cold-applied wax (e.g., lanolin-based or synthetic polymer blends) to penetrate crevices.
• Coverage: Minimum 20–30 µm dry film thickness on all exposed ferrous components.
• Post-Treatment: Inspect for coverage continuity; reapply if damage occurs during loading.

3.3 Efficacy by Shipping Method

Method	Corrosion Risk (Unprotected)	Risk with Wax Protection	Recommended?
RO-RO	High	Moderate	Yes (mandatory)
Bulk Cargo	Very High	High	Limited use; not recommended
Flat Rack	Moderate	Low	Strongly recommended

Note: Wax protection increases preparation cost by ~$120–$180 per unit but reduces post-arrival repair costs by up to 60%.

---

4. Recommendations

For Fleet Managers:

• Prioritize Flat Rack + Wax Spraying for high-value or long-distance exports. Ensures maximum asset protection and compliance with fleet durability standards.
• Use RO-RO only for operational units on short transits (<21 days) with mandatory wax treatment.
• Avoid Bulk Cargo for mission-critical fleet vehicles due to high damage and corrosion exposure.

For Construction Companies:

• Deploy Flat Rack shipping for heavy dump trucks, excavator carriers, and off-road models. Structural support and corrosion resistance are critical in harsh job-site environments post-delivery.
• Implement batch wax treatment at Chinese consolidation yards to achieve economies of scale.

---

5. Operational Workflow (China Export)

1. Sourcing & Transport to China: Used trucks shipped from Crookston, MN to Midwest rail hubs → East Coast ports → Trans-Pacific to Chinese reconditioning centers.
2. Reconditioning & Protection: Mechanical servicing, compliance checks, and full undercarriage wax spraying.
3. Loading & Stowage: Method selected based on destination, cost, and vehicle condition.
4. Documentation: Bill of Lading, Export Declaration, Pre-Shipment Inspection (PSI), and Corrosion Protection Certificate.
5. Destination Handling: Customs clearance, post-arrival inspection, and wax removal (if required).

---

6. Conclusion

For reliable and durable export of used trucks from China, Flat Rack containerization combined with industrial wax spraying offers the highest integrity and long-term value. While RO-RO provides cost and speed advantages, it demands strict corrosion protection protocols. Bulk cargo is not advised for premium used truck exports due to unacceptable risk profiles. SEA LION International recommends integrated logistics planning with protective coating standards aligned with ISO 12944 for corrosion control.
