Date: April 5, 2026
1. Executive Summary
This report evaluates three primary maritime transport methods for exporting new and used excavators from manufacturing hubs in China (e.g., Xuzhou, Shandong) to global construction markets: Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping. Each method is assessed for cost efficiency, equipment safety, transit time, and compatibility with corrosion protection protocols, including wax-based anti-seawater coatings. Recommendations are tailored for fleet procurement and logistics optimization.
2. Shipping Method Comparison
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Loose Stowage) | Flat Rack Container |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed on/off | Crane-lifted, secured in hold | Crane-lifted onto open platform |
| Excavator Size Suitability | Up to 35-ton class | All sizes (including 50+ ton) | All sizes (modular assembly OK) |
| Typical Transit Time | 18–28 days (Asia to EU/MEA) | 22–35 days | 20–30 days |
| Port Infrastructure | Requires RO-RO terminal | Standard bulk terminal | Container terminal with heavy lift |
| Cargo Insurance Cost | Low (minimal handling) | Medium (increased risk) | Medium-High (exposed load) |
| Average Cost (per unit, 20–25t) | $3,200–$4,000 | $2,800–$3,600 | $4,500–$5,800 |
| Risk of Physical Damage | Low (direct roll) | Medium (rigging, stacking) | High (exposure, weather) |
| Customs Clearance | Fast (pre-inspected units) | Standard | Standard (subject to container checks) |

3. Corrosion Protection: Wax Spraying Protocol
Marine export exposes excavator undercarriages, hydraulic cylinders, and structural joints to salt-laden air and condensation. To mitigate galvanic and pitting corrosion during transit, industrial-grade wax spraying is specified as a mandatory pre-shipment treatment.
3.1 Wax Application Specifications
| Parameter | Specification |
|---|---|
| Wax Type | Solvent-based, hydrophobic synthetic polymer (e.g., Dinitrol 4722, Fluid Film) |
| Spray Coverage | Full undercarriage, track links, boom pins, cylinder rods, cavity interiors |
| Coating Thickness | 50–75 microns (measured via wet film gauge) |
| Curing Time | 4–6 hours (ambient 25°C) prior to loading |
| Salt Spray Resistance | >500 hours (ASTM B117 compliance) |
| Removal Process | Biodegradable degreaser + pressure wash (post-delivery) |
3.2 Method-Specific Protection Efficacy
- RO-RO: High protection retention (enclosed vessel, low moisture ingress). Wax layer remains intact.
- Bulk Cargo: Moderate protection (humidity control varies; wax essential for hold-stowed units).
- Flat Rack: Critical protection layer (direct exposure to sea spray; wax + breathable tarp overlay recommended).
Note: SEA LION mandates wax treatment for all excavators shipped via sea. Non-compliant units void transport warranty.
4. Operational Recommendations
4.1 RO-RO – Preferred for Standard Fleets
- Use Case: Delivery of 10–30 operational excavators (15–35t class).
- Advantages: Fast turnaround, low damage rate, ideal for just-in-time project deployment.
- Constraint: Limited availability on non-primary trade routes (e.g., West Africa, Central America).
4.2 Bulk Cargo – High-Volume, Cost-Driven
- Use Case: Export of 50+ units for large infrastructure tenders.
- Advantages: Lowest per-unit cost, flexible stowage.
- Constraint: Requires disassembly for oversized units; higher inspection scrutiny.
4.3 Flat Rack – Oversized & Modular Units
- Use Case: Excavators >40t, or with attachments (e.g., hydraulic breakers, long-reach booms).
- Advantages: Accommodates non-standard dimensions.
- Constraint: Higher freight + insurance costs; mandatory wax + tarpaulin sealing.
5. Compliance & Documentation
All shipments must include:
– Bill of Lading (B/L) with HS Code 8429.52 (excavators)
– Certificate of Origin (China CO)
– Pre-shipment Inspection Report (PSI) per SGS or Bureau Veritas
– Wax Application Certificate (signed by approved applicator)
6. Conclusion
For fleet managers and construction logistics planners, RO-RO is optimal for operational efficiency and equipment integrity, particularly for standard-sized excavators. Bulk cargo remains cost-effective for large-volume, budget-driven projects, while Flat Rack is indispensable for oversized configurations. In all cases, industrial wax spraying is non-negotiable to ensure corrosion-free delivery and warranty compliance.
SEA LION International recommends integrated logistics packages combining method-specific transport with certified corrosion protection to minimize downtime and field maintenance post-import.
