Subject: Logistics Solutions for Exporting HOWO Prime Mover with Trailer from China
Document Code: ISR-LOG-2026-001
Revision: 1.0
Date: 2026-04-05
Executive Summary
This report evaluates three primary maritime transport methods for exporting the HOWO Prime Mover with Trailer 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 Container shipping in terms of cost, transit time, vehicle protection, and logistical efficiency. Special consideration is given to wax-based anti-corrosion treatment to mitigate seawater exposure during ocean transit.
1. Equipment Overview
| Parameter | Specification |
|---|---|
| Vehicle Model | HOWO A7 6×4 Prime Mover + 3-Axle Low-bed Trailer |
| Gross Vehicle Weight (GVW) | 40,000 kg |
| Dimensions (L×W×H) | 16.5 m × 2.5 m × 4.0 m |
| Fuel Type | Diesel |
| Origin Port | Qingdao Port, China |
| Target Destinations | Middle East, Africa, Southeast Asia, South America |
2. Shipping Method Comparison
| Criteria | RO-RO (Roll-on/Roll-off) | Bulk Cargo | Flat Rack Container |
|---|---|---|---|
| Loading Method | Self-driven onto vessel via ramps | Lifted by vessel cranes or shore-based heavy lift | Secured on open-top flat rack, containerized |
| Vehicle Protection | Moderate (exposed to salt spray on deck) | Low (exposed to weather, ballast handling) | High (controlled lashings, optional tarpaulin cover) |
| Transit Time | 18–28 days (direct routes) | 22–35 days (port congestion, handling delays) | 20–30 days (subject to container availability) |
| Port Infrastructure Required | RO-RO terminal with ramp access | Heavy-lift crane (>50T), open laydown area | Standard container terminal with CFS access |
| Cost (USD per unit) | $3,800 – $4,500 | $3,200 – $4,000 | $5,200 – $6,800 |
| Risk of Damage | Medium (chassis stress, salt exposure) | High (rigging damage, shifting) | Low (engineered securing, ISO compliance) |
| Customs Clearance | Straightforward (whole unit) | Complex (break-bulk declaration) | Standard container process |
| Scalability (Fleet Orders) | High (up to 50+ units per vessel) | Medium (space and crane limits) | Medium (limited flat rack availability) |
| Environmental Exposure | High (open deck, direct sea spray) | Very High | Moderate (elevated, but exposed top/sides) |
3. Corrosion Protection: Wax Spraying Treatment
To ensure long-term integrity during maritime transport, anti-corrosion wax spraying is strongly recommended for all HOWO units prior to shipment.
Treatment Protocol:
| Parameter | Specification |
|---|---|
| Product Type | Solvent-based, hydrophobic wax coating (e.g., Waxoyl HD390 or equivalent) |
| Application Method | High-pressure spray + brush detailing |
| Coverage Areas | Undercarriage, chassis rails, suspension components, wheel hubs, trailer bogies |
| Thickness | 25–40 μm (dry film) |
| Drying Time | 4–6 hours (ambient 25°C) |
| Duration of Protection | Up to 6 months (open sea conditions) |
| Compliance | ISO 9227 (salt spray tested), VOC-compliant formulations |
Note: Wax treatment must be applied 72 hours prior to loading to ensure full curing. Post-discharge inspection and wax residue cleaning are advised before commissioning.
4. Method Recommendation by Use Case
| Customer Profile | Recommended Method | Rationale |
|---|---|---|
| Large Fleet Orders (>20 units) | RO-RO | Cost-effective, rapid loading, minimal port infrastructure needed at destination |
| Remote Sites, Limited Port Access | Flat Rack | Secure transport, compatibility with inland heavy haulage, better protection |
| Budget-Constrained Projects | Bulk Cargo | Lowest cost, but requires robust post-arrival inspection and rework planning |
| High-Value or Precision Equipment | Flat Rack + Wax Spray | Maximum protection, traceable handling, reduced corrosion risk |
5. Operational Recommendations
- Pre-Shipment Preparation
- Drain and refill fuel with stabilizer.
- Disconnect battery; seal electrical connectors.
- Inflate tires to 80% of operating pressure.
-
Apply wax spray and document coverage (photographic log).
-
Lashing & Securing
- RO-RO: Use 4-point wheel chocks + lashing straps (SWL ≥ 5T).
- Flat Rack: ISO twist locks + diagonal tension straps.
-
Bulk: Steel slings with padding at load points.
-
Insurance & Documentation
- Declare full replacement value.
- Include wax treatment certification in shipping dossier.
- Obtain marine survey pre-loading.
6. Conclusion
For the export of HOWO Prime Movers with Trailers from China, RO-RO shipping offers the optimal balance of cost and scalability for fleet deployments. However, Flat Rack transport combined with industrial-grade wax spraying is superior for corrosion-sensitive environments and high-reliability operations. Bulk cargo is discouraged except for budget-limited projects with post-arrival refurbishment capacity.
SEA LION International recommends integrating mandatory anti-corrosion wax treatment across all shipping modes to extend equipment service life and reduce field failures.
