SEA LION International Trade Co., Ltd. | Heavy Equipment Solutions Division
EXECUTIVE OVERVIEW: CERTIFIED USED TRUCKS FOR DEMANDING OPERATIONS
SEA LION International delivers operationally validated heavy-duty truck platforms specifically engineered for sustained performance in mining extraction cycles, long-haul logistics corridors, and large-scale civil construction environments. Our certified pre-owned (CPO) fleet—sourced exclusively from SINOTRUK HOWO, SHACMAN F3000/F5000, and XCMG mining/concrete series—undergoes a rigorous, standardized refurbishment protocol exceeding ISO 9001:2015 standards. This program directly addresses the critical operational and financial constraints faced by fleet managers in capital-intensive sectors:
-
Total Cost of Ownership (TCO) Reduction:
Acquisition costs are 35-50% lower than equivalent new units, while maintaining 85-90% of the original operational lifespan. This preserves capital for core project investment without compromising on payload capacity (30-100 MT), terrain adaptability, or fuel efficiency (post-refurbishment verified within 5% of OEM specifications). -
Operational Continuity Assurance:
Each unit undergoes a 127-point technical validation, including:- Powertrain dynamometer testing (engine/transmission/differential)
- Structural frame integrity assessment (laser alignment, stress corrosion checks)
- Critical safety system recalibration (ABS, EBS, retarders)
- Replacement of all wear-limited components (brake linings, suspension bushings, hydraulic seals) using 100% OEM-sourced parts from authorized SINOTRUK/SHACMAN/XCMG channels.
-

INDUSTRIAL SPECIFICATION REPORT 2026
SEA LION International – Heavy Equipment Logistics Division
Document ID: SL-LOG-ISR-2026-04
Effective Date: 01 April 2026
Executive Summary
This report provides a technical evaluation of maritime logistics solutions for the export of certified used trucks from China to global construction and fleet operations. SEA LION International presents a comparative analysis of three primary shipping modalities—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack containerized transport—optimized for durability, cost-efficiency, and corrosion protection. Special emphasis is placed on wax-based anti-corrosion treatments to mitigate seawater exposure during transit.
Target stakeholders include fleet managers, procurement officers, and logistics directors within construction firms and heavy equipment operators sourcing reliable, cost-effective used trucks from Chinese OEM-certified surplus pools.
1. Scope & Application
- Commodity: Certified used heavy-duty trucks (6×4, 8×4 configurations), medium-duty dump trucks, and prime movers (GVWR: 18,000–44,000 kg)
- Origin: Major Chinese ports (Shanghai, Qingdao, Guangzhou, Tianjin)
- Destination: Global (Middle East, Africa, Southeast Asia, Latin America)
- Certification: Pre-shipment inspection per ISO 3834 & JIS D 1601 standards; full maintenance history and emissions compliance (Euro IV/V) verified
- Objective: Optimize transport method selection based on equipment integrity, transit time, cost, and corrosion risk
2. Comparative Shipping Method Analysis
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Lo-Lo) | Flat Rack Container (20’/40′) |
|---|---|---|---|
| Loading Mechanism | Driven on/off vessel via stern ramp | Lifted by crane (Lo-Lo) or via conveyor | Secured via lashing on open-frame container |
| Vehicle Compatibility | Operational units only (must self-propel) | Operational or non-operational (towable) | All types, including oversized or damaged units |
| Cargo Density (Units per Vessel) | High (200–500 trucks per vessel) | Medium (100–300, depending on crane capacity) | Low to Medium (3–5 per 40′ FR) |
| Port Infrastructure Required | RO-RO terminal with ramp access | Conventional multi-purpose terminal | Container terminal with FR handling capability |
| Transit Time (Shanghai → Dubai) | 18–22 days | 24–30 days | 20–25 days |
| Average Cost per Unit (USD) | $1,100–$1,400 | $1,600–$2,000 | $2,200–$2,800 |
| Risk of Handling Damage | Low (minimal lifting) | Medium (crane sling stress) | High (lashing point failure, shifting) |
| Weather Exposure | Partial (decks exposed) | High (open hold or deck) | Full (no overhead cover) |
| Best Suited For | High-volume, operational fleets | Mixed condition units, limited RO-RO access | Oversized, non-standard, or disassembled units |
3. Corrosion Protection Protocol: Wax Spraying System
Seawater-induced corrosion is the primary degradation risk during maritime transport. SEA LION International implements a multi-stage wax-based anti-corrosion treatment prior to shipment:
Treatment Process:
- Pre-Cleaning: High-pressure freshwater wash to remove salts, dust, and organic residues
- Cavity Wax Injection: Application of alkyl ketene dimer (AKD)-based wax emulsion into chassis cavities, frame rails, and undercarriage voids (penetration depth: 8–12 mm)
- Surface Coating: Electrostatic spray of marine-grade microcrystalline wax (melting point: 70–75°C) on exposed metal surfaces (radiator supports, suspension arms, fuel tanks)
- Drainage Check: Verification of open drain holes to prevent moisture entrapment
Performance Metrics:
| Parameter | Specification |
|---|---|
| Salt Spray Resistance (ASTM B117) | >1,000 hours to red rust |
| Film Thickness | 25–40 µm (dry) |
| Reversibility | Fully removable via industrial degreaser (alkaline pH 10–11) |
| Compatibility | Safe for rubber bushings, wiring harnesses, and painted surfaces |
Note: Wax treatment is mandatory for all units shipped via Bulk Cargo and Flat Rack; recommended for RO-RO in high-humidity routes.
4. Operational Recommendations
| Use Case | Recommended Method | Rationale |
|---|---|---|
| Large Fleet Procurement (≥50 units) | RO-RO | Lowest cost per unit, fastest turnaround, minimal handling |
| Mixed-Condition Units (non-operational) | Bulk Cargo | Accommodates non-driveable trucks; moderate cost |
| Oversized or Custom-Bodied Trucks | Flat Rack | Structural flexibility; full visibility for inspection |
| High Corrosion-Risk Regions (e.g., tropical maritime) | All methods + Wax Spray | Mandatory protection against chloride ingress |
5. Compliance & Certification
- IMO Code Compliance: All shipments adhere to the International Code for the Safe Carriage of Heavy Cargo and Breakbulk Cargoes (CSS Code)
- Lashing Standards: DIN 75410-3 for RO-RO; ISO 1496/2 for Flat Rack
- Documentation: Bill of Lading, Pre-shipment Inspection Certificate (PSI), Wax Treatment Log, and Corrosion Protection Declaration provided with each consignment
6. Conclusion
For fleet managers and construction companies sourcing certified used trucks from China, RO-RO shipping represents the optimal balance of cost, speed, and equipment safety for operational units. Flat Rack remains essential for non-standard configurations, while Bulk Cargo offers flexibility for mixed-condition fleets.
Universal application of wax-based corrosion protection is non-negotiable for preserving asset integrity across all modalities. SEA LION International enforces this protocol across its logistics network to ensure delivered units meet operational readiness standards upon arrival.
