---

3. Corrosion Protection: Wax Spraying Protocol

Seawater exposure during maritime transport poses a significant risk to undercarriages, chassis frames, and engine compartments of used trucks. SEA LION International mandates a wax-based anti-corrosion treatment for all exported stoops.

Recommended Wax Spraying Procedure:

• Product Type: Solvent-based, lanolin-enriched corrosion inhibitor (e.g., Dinitrol LS 2000, Fluid Film)
• Application Method: High-pressure spray (200–300 psi)
• Coverage Areas:
• Chassis rails and crossmembers
• Wheel wells and suspension components
• Under-hood engine mounts and brackets
• Fuel and brake lines
• Thickness: Minimum 30–50 µm dry film thickness
• Curing Time: 24 hours pre-shipment (ambient 25°C)
• Reapplication: Advised after discharge if long-term storage expected

Note: Wax film provides sacrificial barrier protection and self-healing properties under vibration—critical for rough sea conditions.

---

4. Operational Recommendations

Shipping Method	Use Case Recommendation	Corrosion Mitigation Add-Ons
RO-RO	High-volume fleet exports; operational units	Full wax spray + plastic fender covers
Bulk Cargo	Non-running units; oversized configurations	Wax spray + VCI (Vapor Corrosion Inhibitor) bags in cab
Flat Rack	Premium units; mixed cargo loads	Wax spray + desiccant loading + tarpaulin wrap

---

5. Compliance & Documentation

All shipments must comply with:
– IMSBC Code (for Bulk Cargo)
– CTU Code (for Flat Rack containers)
– IMO RO-RO Safety Guidelines (SOLAS Chap. VI/VI-1)
– Customs Declaration: Accurate HS Code 8704 (used trucks) with condition certification

---

6. Conclusion

For fleet managers and construction companies exporting stoops from China, RO-RO shipping offers the optimal balance of cost and efficiency for operational trucks. Flat Rack containers are recommended for high-value or mixed-load scenarios requiring enhanced security. Bulk Cargo is viable only for non-operational units where cost is secondary to accessibility.

Mandatory wax-based corrosion protection is non-negotiable for all methods to ensure equipment integrity upon arrival. SEA LION International enforces pre-shipment inspection and treatment verification at origin depots.
