– Failure Rate: 0.8% at 12 months (vs. industry average 4.2% for non-SEA LION refurbished units).

---

WHY SEA LION DEFINES “BEST USED TRUCK”

Generic “certified pre-owned” programs prioritize aesthetics over structural integrity. SEA LION’s process targets construction-specific failure modes:
– Chassis fatigue from repeated dump-body articulation.
– Engine contamination from airborne silica/dust.
– Corrosion from de-icing chemicals/cement.
– Tire damage from sharp aggregate.

Only units passing all 4 phases with zero critical deviations (per Table 3) earn SEA LION certification. This eliminates the “hidden defect risk” inherent in conventional used-truck procurement, delivering predictable lifecycle costs and job-site reliability.

---

3. Corrosion Mitigation: Wax Spraying Protection System

Marine transport exposes vehicles to high-salinity environments, accelerating corrosion on undercarriages, chassis frames, and electrical systems. SEA LION International recommends the application of industrial-grade wax-based anti-corrosion treatment prior to shipment.

Wax Spraying Specifications:

Parameter	Specification
Product Type	Solvent-based, high-adhesion wax (e.g., Dinitrol LS 800 or equivalent)
Application Method	High-pressure spray (20–30 bar)
Coverage Areas	Undercarriage, wheel wells, frame rails, suspension components, exhaust system
Film Thickness	80–120 microns (dry)
Salt Spray Resistance (ASTM B117)	>500 hours
Application Timing	Pre-loading, within 72 hours of shipment
Curing Environment	Ambient temperature (15–25°C), low humidity

Benefits:
– Reduces saltwater penetration by 70–85%
– Preserves resale value and mechanical integrity
– Extends service life in coastal and humid operational zones

Note: Wax treatment is strongly advised for RO-RO and Bulk Cargo shipments due to direct exposure. Flat Rack units benefit from supplementary waxing despite partial enclosure.

---

4. Recommended Use Cases by Industry Segment

Industry	Recommended Shipping Mode	Rationale
Construction Firms (Large Fleets)	RO-RO	Cost-efficient for multiple drivable units; fast turnaround at destination ports with RO-RO facilities
Remote Site Operators (Non-Running Units)	Bulk Cargo	Lower cost for non-operational trucks; suitable when port has heavy-lift cranes
High-Value or Custom Trucks (e.g., Crane Carriers, Articulated Dump Trucks)	Flat Rack	Maximum protection, secure lashing, compatibility with oversized dimensions

---

5. Compliance & Documentation

All shipments must comply with:
– IMO Code of Safe Practice for Cargo Stowage and Securing (CSS Code)
– China Customs Export Declaration (Used Mechanical Equipment)
– Pre-shipment Inspection (PSI) Certificate (required by many destination countries)
– Bill of Lading (B/L) specifying cargo type, stowage method, and protective treatments applied

---

6. Conclusion & Recommendations

For fleet managers and construction companies sourcing used trucks from China:

• RO-RO is optimal for drivable, standard-spec trucks when cost and speed are priorities.
• Bulk Cargo offers the lowest cost but requires robust corrosion protection and crane-capable ports.
• Flat Rack provides superior protection and is ideal for high-value or non-standard units despite higher cost.

Critical Recommendation: Implement wax-based anti-corrosion treatment on all units prior to shipment, regardless of method. This single measure significantly reduces post-import repair costs and extends operational lifespan in harsh environments.

SEA LION International advises pre-qualifying port infrastructure at destination terminals and conducting corrosion audits upon arrival to ensure compliance with fleet maintenance standards.
