3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose ferrous components to salt-laden air and condensation, accelerating oxidation. For used trucks with pre-existing wear, corrosion mitigation is essential to maintain residual value and operational readiness post-transit.

3.1 Industrial Wax Spraying System

• Material: Solvent-based anti-corrosion wax (e.g., Lanocote® or equivalent ISO 12944-compliant formulation).
• Application Method: High-pressure spray (15–20 bar), full undercarriage and chassis coverage.
• Target Zones: Frame rails, suspension mounts, fuel tanks, brake lines, wheel hubs.
• Film Thickness: 30–50 μm (measured via magnetic gauge).
• Curing Time: 4–6 hours at 20°C ambient.
• Performance: Withstands 120-hour salt spray test (ASTM B117).

3.2 Implementation Workflow

1. Pre-treatment: Degrease and dry undercarriage (70°C forced-air drying).
2. Spray application using robotic or manual boom systems.
3. Post-application inspection (adhesion and coverage verification).
4. Documentation: Certificate of Protection (CoP) issued per unit.

Note: Wax protection increases per-unit prep cost by $45–$60 but reduces post-arrival reconditioning by up to 60%.

---

4. Methodology Recommendation Matrix

Use Case	Recommended Method	Rationale
High-volume, operational trucks	RO-RO	Fast loading, low handling damage, cost/unit optimal
Non-operational or heavily damaged units	Bulk Cargo	Lower cost, tolerates non-functional units
Oversized or irregular dimensions	Flat Rack	Accommodates width/height beyond standard limits
High-corrosion-risk routes (e.g., tropical maritime)	RO-RO + Wax Spray	Mandatory protection despite exposure
Regulatory-sensitive destinations	Flat Rack	Containerized shipment simplifies customs audit

---

5. Risk Mitigation & Compliance

• SOLAS Compliance: Verified gross mass (VGM) required for all containerized units.
• IMSBC Code: Bulk shipments must classify trucks as “Heavy Cargo” with lashing plan.
• Environmental Standards: Wax formulations must be non-toxic and biodegradable (OECD 301B).
• Pre-shipment Inspection: ISO 17987-compliant diagnostics recommended for engine and drivetrain.

---

6. Conclusion

For fleet managers and construction firms sourcing used trucks under 20,000 RMB from China, RO-RO shipping with industrial wax spraying presents the optimal balance of cost, speed, and asset preservation. While Bulk Cargo offers lower nominal freight rates, increased damage and rework costs erode savings. Flat Rack remains necessary for non-standard units but is cost-prohibitive for high-volume procurement.

SEA LION International recommends:
– Implement wax spraying as standard for all maritime exports.
– Prioritize RO-RO for operational units on high-humidity routes.
– Conduct lifecycle cost analysis (LCA) inclusive of post-arrival reconditioning.
