Shipping & Logistics Solutions
INDUSTRIAL SPECIFICATION REPORT 2026
Prepared by: SEA LION International – Engineering & Logistics Division
Subject: Export Logistics Solutions for HOWO 6×4 Dump Trucks from China
Target Audience: Fleet Managers, Construction Equipment Procurement Officers, Logistics Supervisors
Executive Summary
This report evaluates three primary maritime transport methods for exporting HOWO 6×4 Dump Trucks from manufacturing hubs in China (e.g., Jinan, Qingdao) to global project sites. The analysis compares Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack (Containerized) shipping solutions based on cost, handling efficiency, equipment protection, and operational compatibility. Special emphasis is placed on wax-based anti-corrosion treatment to mitigate seawater exposure during transit.
1. Equipment Profile: HOWO 6×4 Dump Truck
| Parameter | Specification |
|---|---|
| GVW (Gross Vehicle Weight) | 31,000 – 33,000 kg |
| Dimensions (L×W×H) | ~8,500 × 2,500 × 3,500 mm |
| Unladen Weight | ~15,000 kg |
| Drive Configuration | 6×4 (Triple Axle, Rear Dual Wheels) |
| Fuel Type | Diesel (CN-6 Emission Standard) |
| Origin Ports (China) | Qingdao, Shanghai, Tianjin, Lianyungang |
2. Comparative Logistics Solutions
| Criteria | RO-RO Shipping | Bulk Cargo Shipping | Flat Rack Container (20’/40′) |
|---|---|---|---|
| Loading Method | Self-propelled onto vessel | Crane-lifted into hold | Crane-lifted onto open-top platform |
| Handling Time (per unit) | 15–25 minutes | 45–75 minutes | 30–50 minutes |
| Vessel Type | Pure Car/Truck Carrier (PCTC) | Handymax / Panamax Bulk Carrier | Container Ship |
| Port Infrastructure | Requires RO-RO ramp & clearance | Heavy-lift crane, open berth | Standard container terminal |
| Cargo Density Efficiency | High (stacked decks) | Moderate (mixed with other bulk) | Low (1–2 units per 40′ FR) |
| Transit Time (Asia to MENA) | 22–28 days | 26–34 days | 24–30 days |
| Insurance Cost (per unit) | Moderate | High | Moderate to High |
| Risk of Physical Damage | Low (drivable, minimal lifting) | High (rigging, crane handling) | Medium (secure lashing critical) |
| Suitability for 6×4 Trucks | Optimal | Feasible with planning | Feasible for limited volumes |
3. Corrosion Protection: Wax Spraying System
Exposure to salt-laden maritime environments necessitates robust anti-corrosion measures during ocean transit.
Recommended Protocol: Industrial Wax Spraying (ASTM D1746 Compliant)
| Feature | Specification |
|---|---|
| Coating Type | Solvent-based, hydrophobic corrosion inhibitor |
| Application Method | High-pressure spray (undercarriage, chassis) |
| Coverage Areas | Frame rails, suspension, fuel tanks, axles |
| Film Thickness | 25–35 µm (dry) |
| Salt Spray Resistance (ASTM B117) | >500 hours (no red rust) |
| Drying Time | 6–8 hours (ambient, 25°C) |
| Removability | Biodegradable solvent or hot water wash |
Note: Wax treatment is mandatory for all HOWO units shipped via RO-RO and Flat Rack due to prolonged deck exposure. Bulk cargo units benefit from internal hold protection but still require waxing for coastal unloading phases.
4. Operational Recommendations
| Solution | Best For | Limitations |
|---|---|---|
| RO-RO | High-volume fleet deliveries; time-sensitive projects | Limited to RO-RO-capable destination ports |
| Bulk Cargo | Cost-sensitive, mixed cargo shipments | High risk of handling damage; scheduling inflexibility |
| Flat Rack | Oversized units; non-operational or damaged units | Higher cost per unit; lashing certification needed |
5. Cost Analysis (FOB Qingdao to Jebel Ali, UAE – Per Unit)
| Method | Base Freight (USD) | Lashing/Securing | Wax Treatment | Total (Est.) |
|---|---|---|---|---|
| RO-RO | $1,850 | $120 | $95 | $2,065 |
| Bulk Cargo | $1,600 | $300 | $95 | $1,995 |
| 40′ Flat Rack | $2,300 | $450 | $95 | $2,845 |
Note: Costs exclude insurance, customs, and inland logistics.
6. Conclusion
For fleet managers and construction firms procuring HOWO 6×4 Dump Trucks from China:
- RO-RO is the preferred method for operational units due to speed, safety, and reduced handling.
- Bulk Cargo offers marginal cost savings but increases damage risk and delays.
- Flat Rack is suitable for non-running units or mixed-container shipments but is cost-prohibitive for large fleets.
Critical Success Factor: All units must undergo industrial wax spraying pre-shipment to ensure long-term chassis integrity under marine conditions.
SEA LION International recommends RO-RO with certified anti-corrosion treatment as the optimal export solution for HOWO 6×4 fleets in 2026.
