3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose metal surfaces to salt-laden air and condensation, accelerating corrosion—especially in coastal discharge zones. To preserve truck integrity during 30+ day voyages, SEA LION International mandates the Industrial Wax Spraying Protection (IWSP) System for all exported units.

IWSP Specifications:

• Material: Solvent-based, hydrophobic synthetic wax (ASTM D130 compliant)
• Application Method: High-pressure electrostatic spraying
• Coverage Areas: Undercarriage, chassis rails, suspension components, wheel hubs, exhaust systems
• Thickness: 25–35 microns (measured via Elcometer 456)
• Salt Spray Resistance: 500+ hours (per ASTM B117 testing)
• Reapplication Interval: Recommended after 5 years or post-heavy washdown

Note: Trucks treated with IWSP show 78% lower incidence of structural corrosion after 12 months in tropical port storage (based on 2025 SEA LION field trials, n=142 units).

---

4. Method Recommendation by Use Case

Use Case	Recommended Method	Rationale
Large Fleets (50+ units), Standard Models	RO-RO	Cost-effective, rapid loading, low damage risk
Mixed Cargo, Budget-Constrained Projects	Bulk Cargo	Lower freight cost; acceptable for short-term deployment
Oversized/Heavy Equipment (e.g., Crane Trucks, Mixers)	Flat Rack	Structural support for non-standard dimensions
High-Resale Value or Premium Reconditioned Units	RO-RO + IWSP	Optimal protection and presentation

---

5. Operational Recommendations

• Pre-Shipment Inspection: Conduct ISO 14613:2023-compliant checks for fluid levels, battery isolation, and tire pressure.
• Wax Application Timing: Apply IWSP within 72 hours pre-loading; avoid application in >85% RH environments.
• Lashing Compliance: Adhere to CTU (Cargo Transport Unit) Code for all securing procedures.
• Insurance: Declare full asset value with marine corrosion endorsement.

---

6. Conclusion

For fleet managers and construction firms exporting used trucks through Chinese ports, RO-RO shipping combined with industrial wax spraying offers the optimal balance of cost, protection, and scalability. While Bulk Cargo presents lower upfront costs, its higher risk profile limits suitability for long-term asset deployment. Flat Rack remains essential for non-standard vehicles but incurs premium handling costs.

SEA LION International recommends integrating IWSP as a standard protocol across all export streams to ensure equipment longevity and customer satisfaction in corrosive tropical and coastal markets.
