Target Audience: Fleet Managers, Construction Equipment Procurement Officers, and Project Logistics Planners

---

Executive Summary

This report evaluates three primary maritime logistics methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of micro excavators from manufacturing hubs in China (e.g., Xuzhou, Changsha, Qingdao) to global construction markets. The analysis focuses on cost-efficiency, equipment protection, transit reliability, and compatibility with industrial-grade corrosion prevention measures, including wax-based anti-seawater coatings.

Average Cost per Unit (USD)	$1,200 – $1,600	$900 – $1,300	$1,800 – $2,400
Best For	High-volume fleet deliveries	Non-urgent, cost-sensitive shipments	Oversized or non-standard units

---

3. Corrosion Protection: Wax Spraying Protocol

Micro excavators are highly susceptible to saltwater-induced corrosion during maritime transit, particularly on undercarriage components, hydraulic joints, and cooling systems.

Recommended Protection: Industrial Wax Spraying

• Material: Solvent-based, hydrophobic corrosion-inhibiting wax (e.g., Lanocare 3500 or equivalent)
• Application Method: High-pressure spray to all exposed metal surfaces
• Coverage Areas:
• Tracks and rollers
• Hydraulic cylinder rods
• Frame weld joints
• Cooling fins and radiator cores
• Battery terminals and electrical connectors (non-conductive variant)
• Film Thickness: 25–50 µm (measured via DFT gauge)
• Curing Time: 2–4 hours (ambient 20°C)
• Post-Transit Removal: Biodegradable citrus-based degreaser; no residue

Note: Wax protection is compatible with all three shipping methods but is most effective in RO-RO and Flat Rack due to reduced exposure to bilge moisture and condensation common in bulk holds.

---

4. Risk Assessment & Mitigation

Risk Factor	RO-RO	Bulk Cargo	Flat Rack	Mitigation Strategy
Saltwater Exposure	Moderate	High	Moderate	Wax spray + desiccant bags in cab
Physical Impact	Low	High	Low	Wheel chocks, lashing straps (≥5,000 kg)
Moisture Ingress	Low	Very High	Moderate	Silica gel packs, sealed operator cabin
Theft/Vandalism	Low	Moderate	Low	GPS tracking, port surveillance
Delayed Unloading	Low	High	Moderate	Pre-booked terminal slots

---

5. Recommendations

Scenario	Recommended Method	Rationale
Fleet delivery (10+ units)	RO-RO	Cost-per-unit efficiency, rapid loading, lower damage rate
Remote project site, irregular shipments	Flat Rack	Flexibility in routing, compatibility with break-bulk ports
Budget-constrained, non-time-sensitive	Bulk Cargo	Lowest base cost; acceptable if wax protection is rigorously applied

Critical Note: Regardless of method, wax-based anti-corrosion treatment is non-negotiable for all micro excavator exports from coastal Chinese ports due to high humidity and salt-laden air during transit.

---

6. Compliance & Documentation

All shipments must include:
– Bill of Lading (B/L) with cargo description
– Packing List (with serial numbers)
– Certificate of Origin (Form E for ASEAN)
– Fumigation Certificate (if wooden skids used)
– Corrosion Protection Certificate (wax application log)

---

Conclusion

For construction firms and fleet operators sourcing micro excavators from China, RO-RO shipping offers the optimal balance of cost, speed, and equipment integrity, particularly when combined with industrial wax spraying. While Bulk Cargo presents a lower entry cost, its elevated risk profile makes it unsuitable for high-value machinery without extensive protective measures. Flat Rack remains the preferred option for non-standard or wide-body models requiring special handling.

SEA LION International recommends integrating wax corrosion protection into all export workflows as a standard industrial practice to ensure equipment readiness upon arrival.
