Southeast Asia	High humidity, monsoon conditions, cost sensitivity	XCMG XG90 (6×2) w/ marine-grade electrical sealing, modular repair design	32% lower TCO vs. EU equivalents over 5 years (Thailand DOT study)

3. Competitive Differentiation

SEA LION’s 18-year export expertise ensures predictable uptime through:
– Refurbishment Protocol: 217-point inspection, component-level remanufacturing (engines/transmissions), and dynamometer validation to 100% OEM torque curves.
– Supply Chain Integrity: Direct access to SINOTRUK/SHACMAN/XCMG original spare parts (warranty-backed), eliminating counterfeit risk.
– Deployment Velocity: Dedicated RO-RO vessel slots from Charleston port; average 14-day transit to Durban/Dalian/Singapore.

4. Strategic Recommendation

For fleet managers operating in high-stress environments, SEA LION’s Charlotte-refurbished Chinese platforms deliver proven durability at 40–55% of new-unit CAPEX, with quantifiable reductions in unscheduled downtime (field data: ≤8% vs. industry avg. 18%). Our focus on technical transparency—via full maintenance history digitization and component traceability—supports long-term TCO optimization in capital-intensive sectors. Partnering with SEA LION mitigates asset risk while scaling fleet capability in frontier markets.

Fuel Efficiency Analysis

Fuel economy in WD615-powered trucks is influenced by engine calibration, transmission usage, load profile, and terrain. In real-world fleet operations across the Charlotte region:

• Average Fuel Consumption: 28–34 L/100 km (6.9–8.3 mpg)
• Optimal Efficiency Range: Achieved at 1,400–1,600 rpm in top gear (8th–10th) on flat terrain with loads at 80–90% of rated capacity
• ECO Driving Impact: Proper gear shifting and idle reduction can improve efficiency by up to 12%
• DPF & SCR Systems: Post-2018 models include SCR (AdBlue) systems; urea consumption averages 4–6% of diesel volume

These trucks demonstrate favorable fuel-to-load ratios in regional hauling (50–150 mi radius), particularly when operating on consistent routes with predictable payloads.

---

Load Capacity & Operational Suitability

• Rated Payload Capacity: 20,000–24,000 kg (44,092–52,911 lbs), depending on body configuration (dump, flatbed, stake)
• Dump Truck Configurations: Common in Charlotte market; payload optimized for sand, gravel, and demolition debris
• Axle Load Distribution: Even front-to-rear balance under full load ensures compliance and minimizes tire wear
• Gradeability: Capable of sustained 15–18% inclines at full load with proper momentum, making them suitable for hilly construction zones

The HW19710 transmission paired with the WD615 engine provides reliable torque delivery and gear retention under variable loads, reducing driveline shock and improving component longevity.

---

Summary Recommendations

Used trucks in the Charlotte market equipped with the Weichai WD615 engine and HW19710 transmission offer a cost-effective, high-capacity solution for construction and regional hauling. With proper maintenance, these units deliver:

• Proven durability in high-cycle environments
• Acceptable fuel efficiency for Class 8 diesel platforms
• Strong resale value due to component commonality and service network
• Compatibility with standard tire retreading and axle rebuild programs

Fleet managers are advised to verify maintenance logs, AdBlue system health, and tire tread depth (minimum 8/32″ recommended) prior to acquisition.

Document ID: ISR-LOG-2026-0418
Prepared by: SEA LION International – Global Asset Logistics Division

Executive Summary

This report evaluates the technical and operational suitability of three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of used trucks originating from Charlotte, USA, and transshipped through major Chinese export hubs (e.g., Shanghai, Qingdao, Ningbo). The analysis is tailored for fleet managers and construction firms managing large-scale vehicle redeployment or international resale. Special attention is given to corrosion protection via industrial wax spraying to mitigate seawater exposure during transit.

---

1. Overview of Export Logistics Chain

Used trucks from Charlotte are typically consolidated at inland logistics depots, transported via rail or heavy-haul trailers to East Coast U.S. ports (e.g., Savannah, Charleston), then shipped to transshipment hubs in China before final export to target markets in Africa, the Middle East, Southeast Asia, and Latin America.

Key Export Flow:

Charlotte, USA → U.S. East Coast Port → Trans-Pacific/Trans-Indian Route → Chinese Transshipment Port → Final Destination

All shipping modes evaluated below are applicable at the Chinese export leg.

---

2. Comparative Analysis of Shipping Methods

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Lo-Lo)	Flat Rack Container
Vehicle Compatibility	High – ideal for operational trucks; drives on/off	Medium – requires crane handling; suitable for non-operational units	High – accommodates oversized or damaged trucks
Loading/Unloading Speed	Fast (≤ 4 hrs per vessel cycle)	Slow (8–12 hrs due to crane ops)	Moderate (4–6 hrs with spreader lifts)
Cargo Security	Moderate – exposed decks; limited weather protection	Low – open holds; high exposure to moisture and shifting	High – lashing points, structural containment
Corrosion Risk (Seawater)	High – prolonged salt spray exposure	Very High – bilge moisture, poor ventilation	Moderate – elevated position reduces immersion risk
Max Unit Dimensions	L: 18m, W: 2.5m, H: 4.5m	Limited by crane reach and hold clearance	L: 20m (extendable), W: 3.0m, H: 4.7m (open-top)
Cost per Unit (USD)	$1,100 – $1,600	$900 – $1,300 (economical for non-running units)	$1,800 – $2,500 (premium for flexibility)
Insurance Premiums	Moderate	High (due to handling risk)	Low to Moderate
Best For	Operational fleet transfers, high-volume consignments	Salvage units, non-running trucks	Oversized construction vehicles (e.g., excavators, cranes on chassis)

---

3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose steel undercarriages, brake lines, and suspension systems to chloride-laden aerosols, accelerating galvanic and pitting corrosion. To mitigate degradation during 20–45 day transits:

Industrial Wax Spraying Specification:

• Material: Solvent-based, lanolin-infused anti-corrosion wax (e.g., Cosmoline VCI-379 or equivalent)
• Application Method: High-pressure spray (200–300 psi) with rotary nozzle
• Coverage Areas: Frame rails, fuel tanks, axle housings, suspension joints, brake drums
• Film Thickness: 50–75 microns (measured via magnetic gauge)
• Curing Time: 24 hours pre-shipment in climate-controlled bay (15–25°C, RH <60%)
• Compliance Standard: ISO 9227 (Salt Spray Test), ASTM D1748 (Humidity Resistance)

Note: Wax treatment increases protection duration by 3–5x versus untreated units. Full de-wax required upon delivery using biodegradable solvent (e.g., citrus-based degreaser).

---

4. Operational Recommendations

Use Case	Recommended Mode	Rationale
Fleet Relocation (Operational Trucks)	RO-RO	Fast turnaround, minimal handling damage, cost-efficient for volume
Non-Running Units / Salvage	Bulk Cargo	Lower cost; acceptable risk for low residual value assets
Specialized Construction Equipment	Flat Rack	Accommodates irregular dimensions; superior lashing and visibility

---

5. Risk Mitigation Matrix

Risk Factor	RO-RO	Bulk Cargo	Flat Rack
Saltwater Corrosion	High (apply wax + deck tarping)	Very High (mandatory wax + sealed crating)	Moderate (wax + elevated stowage)
Mechanical Damage	Low	High (lifting points stress frame)	Low (custom lashing)
Theft/Vandalism	Moderate (monitored ramps)	High (open holds)	Low (container seal compliance)
Delay Risk (Port Congestion)	Low (dedicated RO-RO berths)	High (shared general cargo cranes)	Moderate

---

6. Conclusion

For fleet managers and construction companies exporting used trucks via Chinese transshipment ports, RO-RO remains the optimal balance of speed, cost, and safety for operational units. Flat Rack containers are indispensable for non-standard or high-value construction vehicles despite higher costs. Bulk cargo is viable only for non-running units where cost is the primary driver.

Mandatory wax spraying is non-negotiable across all modes to ensure asset integrity. SEA LION International recommends integrating wax treatment into pre-shipment conditioning protocols at U.S. consolidation centers to ensure compliance and reduce rework at Chinese ports.

Future logistics planning should consider hybrid models—e.g., RO-RO with post-arrival wax inspection and reapplication in destination ports—to extend service life in high-humidity markets.
