3. Corrosion Protection: Wax Spraying Protocol

Seawater exposure during Pacific transit presents a significant risk of salt-induced corrosion on chassis, undercarriages, brake lines, and electrical connectors. To mitigate degradation, SEA LION International mandates a wax-based anti-corrosion treatment for all exported used trucks.

Wax Spraying Specifications (ASTM D1193-22 Compliant)

Parameter	Specification
Wax Type	Solvent-based, petroleum-derived corrosion inhibitor (C.I. Grade 4)
Application Method	High-pressure spray (2,000 psi) with undercarriage extension nozzles
Coverage Areas	Frame rails, suspension components, fuel tanks, exhaust manifolds, wheel hubs
Dry Film Thickness	25–35 µm (measured via magnetic gauge)
Salt Spray Resistance (ASTM B117)	500+ hours without red rust formation
Reapplication Interval	Required if storage >60 days pre-shipment

Note: Wax treatment is especially critical for Flat Rack and RO-RO units due to direct exposure. Bulk cargo units benefit from reduced airflow but remain at risk due to condensation in holds.

---

4. Method-Specific Risk Assessment

Method	Corrosion Risk	Mechanical Damage Risk	Cost Efficiency	Scalability
RO-RO	Medium	Low	High	High
Bulk Cargo	High (humidity)	Medium (shifting)	Medium	Medium
Flat Rack	Very High	Low–Medium (secure lashing)	Low	Low (space-inefficient)

---

5. Recommendations by Use Case

Fleet Profile	Recommended Method	Rationale
Large fleet renewal (50+ units, operational)	RO-RO	Fast loading, lower damage, cost-effective at scale
Mixed-condition units (non-running, salvage)	Bulk Cargo	Accommodates non-functional units; lower cost
Oversized dump trucks, crane carriers	Flat Rack	Accommodates width/height beyond container limits

---

6. Compliance & Documentation

All shipments must include:
– Bill of Lading (Sea Waybill)
– Export Declaration (Chinese Customs)
– U.S. EPA Engine Certification (for pre-2010 models)
– DOT Conformance Letter
– Wax Treatment Certificate (issued by certified applicator)
– Pre-shipment Inspection Report (SASO/SONCAP if applicable)

---

7. Conclusion

For fleet managers and construction firms sourcing used trucks from China, RO-RO shipping offers the optimal balance of cost, speed, and protection, particularly when combined with industrial-grade wax spraying. While Bulk Cargo presents a lower-cost alternative for non-operational units, it increases corrosion risk due to humidity. Flat Rack remains a niche solution for oversized equipment but demands enhanced anti-corrosion protocols.

SEA LION International recommends integrating wax-based undercarriage protection as a non-negotiable step in pre-shipment preparation to ensure equipment integrity and extend service life upon U.S. arrival.
