Fuel Efficiency Analysis
Fuel economy in the Michigan operating environment (mixed highway, urban, and graded haul routes) was evaluated across 127 monitored units (2020–2023 model years):
- Average Fuel Consumption:
- Loaded (32-ton payload): 28–32 L/100 km (8.3–7.4 mpg)
-
Unloaded / Light Duty: 22–25 L/100 km (10.7–9.4 mpg)
-
Efficiency Drivers:
- Proper gear utilization with HW19710 reduces lugging and over-revving.
- Engine stop-start systems (on post-2021 models) yield 4–6% savings in urban cycles.
-
Aerodynamic retrofits (roof fairings, side skirts) improve highway efficiency by ~5%.
-
Fuel Quality Note:
Weichai WD615 engines require ULSD (Ultra-Low Sulfur Diesel) with <15 ppm sulfur. Biodiesel blends up to B20 permitted with OEM-approved additives.
Load Capacity & Operational Suitability
| Configuration | Max Payload (Michigan DOT Compliant) | Recommended Use Case |
|---|---|---|
| 6×4 Tractor + 40-ft Trailer | 22–25 tons (48,500–55,100 lbs) | Aggregate haul, inter-yard transport |
| 6×4 Dump Truck | 18–20 tons (39,700–44,100 lbs) | On-site earthmoving, road base delivery |
| 8×4 Mixer Configuration | 12–14 cubic yards (9–11 tons) | Ready-mix concrete, time-sensitive pours |
-
Axle Weight Compliance:
Michigan’s bridge formula and axle load limits (e.g., 20,000 lbs on steer, 34,000 lbs on tandem drive) are met when properly loaded. Overloading (>16T/axle) accelerates HC16 axle wear and increases tire failure risk. -
Structural Integrity:
Chassis frames on 2020+ models use 320–360 MPa high-tensile steel. Inspect for stress cracks at fifth-wheel mounts and suspension hangers during pre-purchase inspection.
Summary Recommendations
- For High-Utilization Fleets: Prioritize trucks with WD615.69 (371 hp) and 5.286 axle ratio—optimal balance of speed and torque.
- Maintenance Focus: Monitor HW19710 synchros and Weichai EGR cooler integrity; common wear points after 600,000 km.
- Tire Management: Rotate every 30,000 miles; retread eligibility up to two cycles with proper casing inspection.
- Total Cost of Ownership (TCO): Well-maintained units show 7–9% lower TCO vs. comparable Western OEMs over 5-year cycle (based on Michigan labor and parts pricing).
This specification set supports reliable, cost-effective operations in Michigan’s demanding construction and freight sectors. Pre-acquisition diagnostics are advised to verify engine compression, transmission bearing play, and frame straightness.

Prepared for: Fleet Managers & Construction Companies
Subject: Export Logistics Solutions for Used Trucks from China – Michigan Market Entry
Issuing Authority: SEA LION International – Global Heavy Equipment Logistics Division
Date: April 5, 2026
Executive Summary
This report evaluates three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of used trucks from Chinese ports to Michigan, USA. The analysis is tailored for fleet procurement managers and construction logistics decision-makers requiring cost-effective, secure, and compliant transportation of heavy-duty vehicles. Special attention is given to corrosion mitigation, particularly through industrial-grade wax spraying systems designed to protect against seawater exposure during transit.
1. Transport Modal Comparison: RO-RO vs. Bulk Cargo vs. Flat Rack
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Loose Vessel Loading) | Flat Rack Container |
|---|---|---|---|
| Vehicle Compatibility | High – Ideal for operational trucks with self-propulsion | Moderate – Suitable for non-operational or disassembled units | High – Supports all truck types, including oversized |
| Loading Method | Driven on/off vessel via stern ramp | Craned or slung into hold; no self-movement required | Secured via flat rack container, lifted by crane |
| Port Infrastructure (China) | Major ports: Shanghai, Guangzhou, Qingdao | Widely available; lower port specialization required | Standard container terminals; requires container handling |
| Port Infrastructure (U.S. – Great Lakes Access) | Limited – No direct RO-RO into Great Lakes; transload at East Coast ports (e.g., Baltimore, NY/NJ) required | Not feasible – bulk carriers do not service inland Great Lakes | Feasible – containers transited via intermodal rail to Detroit/Milwaukee |
| Transit Time (China to Michigan) | 35–45 days (including transload and rail) | Not recommended – no direct routing | 30–40 days (sea + rail) |
| Handling Risk | Low – minimal mechanical handling | High – repeated crane lifts increase damage risk | Moderate – secure lashing but crane-dependent |
| Cost (Per Truck Unit) | $2,800–$3,500 | $2,000–$2,600 (excluding inland logistics) | $3,600–$4,200 |
| Security & Vandalism Risk | Moderate – shared deck space | High – unsecured stowage in hold | Low – sealed, ISO-standard container |
| Customs & Documentation | Standard vehicle import protocols | Complex – non-containerized cargo scrutiny | Streamlined – ISO container tracking |
| Best Use Case | Operational fleets, time-sensitive deliveries (if transload acceptable) | Not advised for Michigan-bound used trucks | High-value, oversized, or corrosion-sensitive units |
2. Corrosion Protection: Wax Spraying System Specification
Marine exposure during transit poses significant risk of saltwater-induced corrosion on undercarriages, chassis frames, and exposed metal components. SEA LION International mandates industrial wax encapsulation for all used truck shipments originating from Chinese coastal ports.
Wax Spraying Protocol (SEA LION Standard SL-MEP-2026)
| Parameter | Specification |
|---|---|
| Wax Type | Solvent-based, hydrophobic polymer blend (ASTM D130 compliant) |
| Application Method | High-pressure spray (150–200 psi), full undercarriage coverage |
| Coverage Areas | Frame rails, suspension components, brake lines, fuel tanks, differential housings |
| Thickness | 75–100 µm dry film thickness |
| Salt Spray Resistance | 1,000+ hours per ASTM B117 testing |
| Removal | Biodegradable citrus-based solvent; non-damaging to paint or rubber |
| Application Location | Pre-shipment facility, Dalian or Shanghai (ISO 14644-7 clean environment) |
Note: Wax protection is mandatory for RO-RO and Bulk Cargo shipments. Optional but strongly advised for Flat Rack units due to prolonged exposure during intermodal transfer.
3. Recommended Solution for Michigan Market
Given the inland destination and lack of direct deep-water port access, Flat Rack container shipping via West Coast or East Coast gateway ports with intermodal rail is the optimal solution for used trucks exported from China to Michigan.
Advantages:
- Full compliance with U.S. EPA and DOT import standards for containerized vehicles
- Reduced handling damage and theft risk
- Seamless integration with Class I rail carriers (e.g., CN, NS) to Detroit, Grand Rapids, and Lansing
- Enhanced traceability via GPS-enabled container locks
Limitations:
- Higher base cost vs. RO-RO
- Requires chassis availability at U.S. rail ramps
4. Operational Workflow: China to Michigan
- Preparation (China)
- Vehicle inspection, fuel reduction (<1/4 tank), battery disconnect
-
Industrial wax spraying and documentation (title, export permit)
-
Loading & Stowage
- Flat Rack: Secured with 5-point lashing (DNV-ST-E373 compliant)
-
RO-RO: Parked and wheel-chocked; brake engaged
-
Ocean Transit
- Route: Shanghai → Los Angeles/Long Beach → Rail to Detroit (BNSF/UP)
-
Average transit: 28 days ocean + 5–7 days rail
-
U.S. Entry & Clearance
- CBP and EPA inspection at port of entry
-
DOT compliance verification (FMVSS standards)
-
Final Delivery
- Rail ramp release to local hauler or fleet pickup
5. Conclusion & Recommendations
| Shipping Method | Recommendation | Rationale |
|---|---|---|
| RO-RO | Conditional Use | Cost-effective for large fleets if transload logistics are managed; higher corrosion risk without wax |
| Bulk Cargo | Not Recommended | High damage potential, no direct access to Great Lakes, complex customs |
| Flat Rack | Preferred Solution | Optimal protection, regulatory compliance, and inland delivery integration |
SEA LION Recommendation: Utilize Flat Rack containers with mandatory wax spraying for all used truck exports from China to Michigan. This ensures asset integrity, regulatory adherence, and logistical efficiency across the supply chain.
