3. Corrosion Protection: Wax Spraying System

Marine transport exposes excavators to salt-laden air and condensation, accelerating corrosion—particularly on undercarriages, hydraulic cylinders, and unpainted steel surfaces.

Recommended Protection Protocol:

• Pre-Shipment Treatment: Application of solvent-based synthetic wax coating (e.g., lanolin-derived or petroleum-based formulations) to all exposed metal surfaces.
• Coverage Areas: Track links, rollers, idlers, boom/stick pivot points, counterweight, and undercarriage frame.
• Application Method: High-pressure spray (25–30 bar), followed by brush detailing in crevices.
• Dry Film Thickness: 25–40 µm (meets ISO 12944-2 C5-M marine exposure class).
• Removal: Post-delivery, removable via industrial degreaser or hot water pressure wash (80°C max).

Benefits:

• Forms hydrophobic barrier against saltwater and humidity.
• Self-healing properties under minor abrasion.
• Compatible with all shipping methods; especially critical for RO-RO and Bulk Cargo.

Note: Wax protection is mandatory for all export shipments from Chinese coastal ports (e.g., Shanghai, Qingdao, Nantong) due to high ambient salinity.

5. Recommendations

Scenario	Recommended Method	Rationale
High-volume fleet exports (≥20 units/month)	RO-RO	Fast turnaround, lower labor cost; apply enhanced wax + deck covers.
Budget-constrained projects, inland delivery	Bulk Cargo	Lowest cost; must include full wax spray + VCI desiccants in cab.
High-value, oversized, or custom excavators	Flat Rack Container	Maximum protection, ISO compliance, ideal for crane-accessible sites.

---

6. Compliance & Documentation

All shipments must comply with:
– IMSBC Code (for Bulk)
– CTU Code (for Flat Rack)
– Ro-Ro Safety Guidelines (IMO MSC.1/Circ.1372)
– Customs Export Declaration (China) – Form EX-01
– Certificate of Conformity (CE/ECV) for EU-bound units

Wax application logs and pre-shipment inspection reports must be archived for 3 years.

---

Conclusion

For optimal balance of cost, speed, and asset integrity in exporting Chinese excavators, RO-RO is recommended for standard fleets with wax protection, while Flat Rack ensures maximum preservation for premium units. Bulk Cargo remains viable only when cost is the overriding factor and full corrosion countermeasures are implemented.

Fleet managers and construction logistics planners are advised to integrate wax-based anti-corrosion treatment as a non-negotiable step in the export workflow, regardless of shipping method.
