Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared for: Fleet Managers & Construction Companies
Subject: Logistics Solutions for Exporting Heavy-Duty Dump Trucks from China

---

Executive Summary

This report evaluates three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack shipping—for the export of heavy-duty dump trucks from manufacturing hubs in China (e.g., Qingdao, Shanghai, Guangzhou) to global destinations. The analysis focuses on cost efficiency, transit time, equipment safety, and corrosion mitigation, with specific reference to wax-based anti-corrosion treatments applied prior to shipment.

---

1. Overview of Shipping Methods

Parameter	RO-RO Shipping	Bulk Cargo Shipping	Flat Rack Shipping
Definition	Trucks driven on/off vessel via ramps	Trucks disassembled and stowed in hold	Trucks secured on open, collapsible frames
Suitability	High – for operational vehicles	Low – requires partial disassembly	High – for oversized or non-operational units
Loading Method	Self-propelled	Crane-lifted in sections	Crane-lifted, fully assembled
Typical Vessels	Pure Car/Truck Carriers (PCTCs)	Capesize/Bulk Carriers	Multi-purpose vessels with flat rack capacity
Port Infrastructure	Requires RO-RO terminals	Standard bulk terminals	Heavy-lift capable terminals
Transit Time	25–35 days (Asia to Europe)	30–45 days	28–40 days
Average Cost (USD/unit)	$8,500 – $11,000	$6,000 – $8,500 (disassembled)	$10,000 – $14,000

Note: Cost estimates assume a 40-ton rigid dump truck (e.g., XCMG XDR400, SANY SRT55). Pricing varies by route, fuel surcharges, and port fees.

---

2. Comparative Analysis

Criterion	RO-RO	Bulk Cargo	Flat Rack
Vehicle Integrity	✅ High (no disassembly)	❌ Medium (risk of component damage during reassembly)	✅ High (fully assembled, minimal handling)
Corrosion Risk	Medium (exposed to salt spray)	High (prolonged hold exposure)	Medium-High (fully exposed)
Security & Theft Risk	Low (sealed vessel decks)	Medium (shared cargo space)	Medium (external lashing points)
Customs Clearance	Fast (complete unit)	Slower (components listed separately)	Standard (unitized cargo)
Port Availability	Limited (RO-RO-capable ports)	High (most major ports)	Moderate (specialized cranes required)
Environmental Exposure	Moderate (deck-level salt air)	High (humidity, condensation)	High (full weather exposure)
Insurance Complexity	Low	Medium	Medium-High

---

3. Corrosion Protection: Wax Spraying Protocol

To mitigate seawater-induced corrosion during ocean transit, industrial-grade wax spraying is recommended for all exposed metallic surfaces, including:

• Chassis frames
• Axles and suspension components
• Hydraulic cylinder rods
• Undercarriage and engine mounts

Wax Application Specifications

Parameter	Specification
Wax Type	Solvent-based, hydrophobic synthetic polymer coating (e.g., Dinitrol AVS 80, Waxoyl NV40)
Film Thickness	25–50 µm (uniform coverage)
Application Method	High-pressure spray (200–300 bar)
Curing Time	4–6 hours (ambient 25°C)
Protection Duration	Up to 6 months (open-sea conditions)
Removal Process	Biodegradable solvent wash or steam cleaning upon delivery

Best Practice: Apply wax treatment within 48 hours of final assembly. Conduct post-treatment inspection using adhesion and continuity tests per ISO 8501-1.

---

4. Method Recommendation by Use Case

Scenario	Recommended Method	Rationale
Fleet delivery (operational units)	RO-RO	Fast deployment, minimal post-delivery work, lower mechanical risk
Cost-sensitive, non-urgent shipment	Bulk Cargo	Lower freight cost; viable if reassembly infrastructure exists on-site
Oversized or custom-configured units	Flat Rack	Accommodates non-standard dimensions; secure lashing options

---

5. Operational Recommendations

1. Pre-Shipment Inspection (PSI): Conduct FOC (Free of Charge) PSI per ISO 10472-1 to verify mechanical and electrical integrity pre-loading.
2. Lashing & Securing: For Flat Rack and RO-RO, use ISO-compliant lashing points with ≥ 4-point tie-down per truck (breaking load ≥ 10,000 kg).
3. Desiccant Use: Place silica gel desiccants (min. 500 g/m³) in enclosed cabs and electrical enclosures.
4. Documentation: Include Bill of Lading (B/L), Packing List, Certificate of Origin, and Wax Application Certificate.

---

6. Conclusion

For fleet managers and construction firms importing heavy-duty dump trucks from China, RO-RO shipping offers the optimal balance of speed, safety, and operational readiness. While Flat Rack provides flexibility for non-standard units, and Bulk Cargo reduces freight costs, both entail higher handling risks and longer deployment timelines. Mandatory wax spraying is critical across all methods to ensure corrosion resistance during 30+ day transits across saline marine environments.

SEA LION International recommends integrating wax protection into OEM pre-shipment protocols and selecting RO-RO where port infrastructure permits, to maximize equipment longevity and reduce field maintenance costs.
