Executive Summary
This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of Caterpillar 336-class excavators from manufacturing hubs in China (notably Qingdao, Shanghai, and Nansha) to global construction markets. Each method is assessed based on cost, transit time, equipment protection, handling efficiency, and suitability for high-value machinery. Additionally, the report outlines the implementation of wax-based anti-corrosion protection (wax spraying) to mitigate seawater exposure during transit.

| Vessel Type | Dedicated RO-RO vessel (e.g., NYK RO-RO, Wallenius Wilhelmsen) | Multi-purpose bulk carrier or heavy-lift vessel | Container ship with flat rack slots |
| Port Accessibility | High (major global ports with RO-RO terminals) | Moderate (requires heavy-lift port infrastructure) | High (standard container ports with flat rack handling) |
| Transit Time (China → Middle East / Africa / Latin America) | 18–25 days | 22–30 days | 20–28 days |
| Average Cost (per unit, FOB China) | $4,200 – $5,000 | $3,800 – $4,600 | $5,500 – $6,800 |
| Equipment Protection | Moderate (exposed to salt spray; requires full anti-corrosion prep) | Low (high exposure to moisture, debris, and handling stress) | High (customizable protection; full wrap and wax spray feasible) |
| Risk of Damage | Medium (potential tire/undercarriage wear during roll-off) | High (sway, shifting, contact with other cargo) | Low (secure lashings, isolated positioning) |
| Customs & Documentation | Streamlined (standard RO-RO manifest) | Complex (requires detailed cargo manifest) | Standard container documentation |
| Best For | High-volume fleet shipments to RO-RO-equipped ports | Low-cost transport to developing markets with bulk infrastructure | High-value units requiring maximum protection |
3. Corrosion Protection: Wax Spraying Protocol
Seawater exposure during maritime transport poses a critical risk to excavator integrity, particularly in hydraulic systems, undercarriages, and electrical components. SEA LION International mandates industrial-grade wax spraying as a standard anti-corrosion measure for all CAT 336 exports.
Wax Spraying Specifications
| Parameter | Specification |
|---|---|
| Coating Type | Solvent-based, hydrophobic synthetic wax (e.g., Cosmoline C5 or equivalent) |
| Application Method | High-pressure spray + brush detailing |
| Coverage Areas | Undercarriage, boom/stick pins, track links, radiator fins, hydraulic cylinders, battery compartment |
| Film Thickness | 50–75 µm (dry) |
| Salt Spray Resistance | ASTM B117 compliant (1,000+ hours) |
| Post-Transit Removal | Biodegradable citrus-based solvent; non-abrasive wipe |
| Applicable to All Methods | Yes (mandatory for RO-RO and Bulk; recommended for Flat Rack) |
Note: Wax spraying reduces post-arrival rework by up to 70% and extends equipment service life in coastal construction zones.
4. Method-Specific Recommendations
RO-RO Shipping
- Advantages: Fast turnaround, minimal crane dependency, ideal for operational units.
- Limitations: Limited to functional machines; higher exposure to salt-laden air.
- Recommendation: Use only with full wax spray + breathable poly wrap. Schedule port discharge during dry weather windows.
Bulk Cargo
- Advantages: Lowest cost; suitable for non-operational or damaged units.
- Limitations: High risk of impact and moisture damage; limited insurance coverage.
- Recommendation: Reserve for secondary markets. Apply wax spray + internal desiccants. Avoid during monsoon seasons.
Flat Rack
- Advantages: Maximum visibility and protection; allows full enclosure with tarping or shrink-wrapping.
- Limitations: Higher cost; requires container availability.
- Recommendation: Preferred for premium clients and cold-climate destinations. Combine with wax spray and VCI (Vapor Corrosion Inhibitor) bags.
5. SEA LION International Standard Operating Procedure (SOP-2026-HM)
All CAT 336 exports from China must comply with:
- Pre-shipment Inspection (PSI): Verified operational status, fuel/oil drained (if non-operational), battery disconnected.
- Wax Spraying: Applied within 24 hours of final wash; documented with before/after imaging.
- Securement:
- RO-RO: Wheel chocks + parking brake + GPS tracker.
- Flat Rack: 4-point lashing with 8-ton break load straps.
- Documentation: Bill of Lading, Packing List, Export Declaration, Phytosanitary (if wood dunnage), and Anti-Corrosion Certificate.
Conclusion
For fleet managers and construction firms procuring CAT 336 excavators from China, Flat Rack shipping with wax spraying offers the optimal balance of protection and reliability, despite higher costs. RO-RO remains efficient for functional units destined to developed ports. Bulk Cargo is viable only for cost-sensitive, high-tolerance operations.
SEA LION International recommends wax-based corrosion protection as non-negotiable across all transport modes to ensure equipment readiness upon arrival and minimize warranty claims.
