INDUSTRIAL SPECIFICATION REPORT 2026
EXECUTIVE OVERVIEW: CERTIFIED USED TRUCK OFFERS FOR CRITICAL OPERATIONS

1. Operational Imperative & Market Context

Fleet managers in mining, logistics, and construction face escalating pressure to reduce total cost of ownership (TCO) while maintaining operational continuity in extreme environments. New asset capital expenditure (CAPEX) constraints, coupled with volatile supply chains, necessitate reliable, cost-optimized heavy equipment solutions. SEA LION International addresses this gap through rigorously refurbished used trucks from OEM partners SINOTRUK, SHACMAN, and XCMG, engineered specifically for high-stress applications in resource extraction, bulk haulage, and infrastructure development.

2. Core Application Validity

Certified used trucks from SEA LION deliver proven performance in three critical sectors:
– Mining: 6×4 & 8×4 rigid dump trucks (e.g., SINOTRUK HOWO 371HP) withstand 24/7 operation on unpaved haul roads, with reinforced chassis and drivelines validated for >450,000 km in iron ore/copper operations.
– Logistics: 6×2/8×4 prime movers (e.g., SHACMAN F3000) achieve 95%+ fleet availability in long-haul corridors, optimized for 40+ ton payloads on degraded road networks.
– Construction: XCMG 8×4 concrete mixers and dump trucks integrate site-specific modifications (e.g., extended wheelbases, high-ground clearance) for urban and remote project sites.

3. Regional Preference Drivers: Africa, Russia, Southeast Asia

Market dominance in these regions stems from alignment with operational realities, not cost alone. Key technical and logistical factors include:

Region	Primary Applications	Critical Operational Requirements	SEA LION Solution Advantage
Africa	Open-pit mining, cross-border logistics	Extreme dust tolerance, fuel flexibility (diesel/biodiesel), low-infrastructure resilience	Chassis sealed against particulate ingress; engines calibrated for low-cetane fuels; modular repair kits for remote sites
Russia	Arctic mining, Siberian logistics	Cold-start reliability (-45°C), snow/ice traction, corrosion resistance	Arctic-grade lubricants, dual-battery systems, reinforced undercarriage coatings; EOL testing at -50°C
Southeast Asia	Infrastructure construction, plantation logistics	Monsoon durability, high-humidity corrosion control, narrow-road maneuverability	Epoxy-coated frames, enhanced electrical sealing, compact cab variants (≤2.5m width)

4. SEA LION Value Chain Differentiation

Our 18+ years of export specialization enables unmatched reliability through integrated industrial processes:

Service Pillar	Technical Implementation	Operational Impact
Professional Refurbishment	OEM-standard rebuild protocols; 100+ point inspection; dyno-tested engines/transmissions	30% lower failure rate vs. non-certified used trucks (2025 field data)
Spare Parts Integrity	Direct OEM supply chain; barcode-tracked components; 24-month parts warranty	99.2% first-time fix rate; eliminates counterfeit part risks
Global Logistics	RO-RO vessel coordination; containerized break-bulk for remote sites; customs clearance engineering	14-day avg. port-to-site delivery in Africa/SEA; Russia rail-head integration

5. Strategic Recommendation

For fleet managers prioritizing uptime resilience and predictable TCO in capital-intensive operations, SEA LION’s certified used trucks represent a de-risked asset strategy. Our technical validation against regional environmental stressors—coupled with full-service support—ensures continuity where new-equipment volatility and unverified used markets introduce unacceptable operational risk. This model delivers 40-60% CAPEX reduction versus new units while maintaining 85%+ of original service life, directly supporting ROI targets in volatile commodity and infrastructure cycles.

Executive Summary

This report evaluates three primary maritime logistics methods for exporting used commercial trucks from China: Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack (Flat Rack Containers). The analysis focuses on cost efficiency, transit reliability, cargo protection, and compatibility with industrial-scale fleet relocation. Special emphasis is placed on wax-based anti-corrosion treatments to mitigate seawater exposure during transit.

---

1. Overview of Export Logistics Options

Used truck exports from Chinese ports (e.g., Shanghai, Guangzhou, Qingdao) require robust handling due to vehicle weight, dimensions, and susceptibility to marine environmental stress. The three dominant shipping methods are assessed below.

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Loose Stowage)	Flat Rack Container
Typical Capacity	150–500 vehicles/voyage	50–200 vehicles/voyage	1–3 trucks/unit
Loading Method	Self-driven or towed	Crane-lifted, fixed stowage	Crane-lifted, secured
Port Infrastructure	Dedicated RO-RO terminals	General multipurpose ports	Container terminals
Transit Time (China–MEA/Africa)	18–28 days	22–34 days	20–30 days
Damage Incidence Rate	Low (controlled entry)	High (handling impact)	Medium (exposed sides)
Cost per Unit (USD)	$1,100–$1,600	$900–$1,300	$1,800–$2,500
Reusability of Packaging	N/A	Limited	High (frame reuse)

---

2. Comparative Analysis

2.1 RO-RO (Roll-on/Roll-off)

• Advantages:
• Minimal handling reduces mechanical damage.
• Fast loading/unloading via ramps.
• Ideal for operable trucks; supports fleet-scale batching.

• Lower insurance claims due to secure internal stowage.

• Disadvantages:

• Limited to ports with RO-RO infrastructure.
• Requires functional vehicles (cannot transport non-operational units without trailers).

• Higher base cost compared to bulk.

• Best For: Operational fleets with multiple units bound for Middle East, Africa, or South America.

2.2 Bulk Cargo (Loose Stowage in General Cargo Holds)

• Advantages:
• Lower cost per unit.
• Accommodates non-operational or damaged trucks.

• Flexible port access.

• Disadvantages:

• High risk of impact damage during crane handling.
• Prolonged exposure to humidity and salt air.
• No standardized securing; increased tilt/shift risk.

• Longer port turnaround.

• Best For: Budget-driven exports of mixed-condition units where cosmetic integrity is secondary.

2.3 Flat Rack Container

• Advantages:
• Full structural visibility and access for inspection.
• Suitable for oversized or modified trucks (e.g., crane trucks, mixers).
• Stackable on deck; compatible with standard container logistics.

• Can be sealed with tarpaulins or shrink-wrapping.

• Disadvantages:

• Full exposure to sea spray and solar UV without secondary protection.
• Higher freight cost due to container use.

• Requires specialized lifting equipment.

• Best For: High-value, custom, or oversized construction vehicles requiring traceability and secure transit.

3. Corrosion Protection: Wax Spraying Protocol

All used trucks exported via maritime routes are subject to chloride-induced corrosion from sea-salt aerosols and condensation. SEA LION International mandates the following anti-corrosion treatment:

Wax-Based Undercoating Specification

Parameter	Specification
Wax Type	Solvent-based, lanolin-infused synthetic polymer
Application Method	High-pressure spray (120–150 psi)
Coverage Areas	Chassis rails, suspension mounts, brake lines, fuel tanks, under-hood components
Minimum Film Thickness	25–30 microns (measured via DFT gauge)
Drying Time (Pre-shipment)	24 hours at 20°C, 60% RH
Salt Spray Resistance (ASTM B117)	>720 hours to red rust

• Implementation:
• Conducted at certified pre-shipment treatment centers in Chinese export hubs.
• Post-application QC includes visual inspection and adhesion testing.
• Documentation: Certificate of Conformity (CoC) issued per ISO 9001:2015.

Note: Wax treatment is mandatory for Flat Rack and Bulk Cargo shipments. Recommended for RO-RO units with extended layover or tropical routing.

---

4. Recommendations by Use Case

Client Profile	Recommended Method	Rationale
Large fleet (50+ operable trucks)	RO-RO	Cost-effective per unit, low damage rate, rapid turnaround
Mixed-condition fleet	Bulk Cargo + Wax Spray	Handles non-running units; wax mitigates corrosion risk
Specialized construction vehicles	Flat Rack + Full Enclosure	Accommodates dimensions; wax + tarpaulin ensures protection

---

5. Conclusion

For industrial-scale export of used trucks from China, RO-RO remains the optimal balance of cost, speed, and safety for operable fleets. Flat Rack is superior for non-standard vehicles despite higher cost, while Bulk Cargo suits budget-sensitive, condition-variable consignments—provided corrosion protection is rigorously applied.

Wax-based anti-corrosion spraying is a non-negotiable protective measure, particularly for non-enclosed transport methods. SEA LION International enforces this standard across all logistics channels to ensure asset integrity upon delivery.
