• Undercarriage (track links, rollers, idlers)
• Exposed hydraulic cylinders
• Unpainted weld zones and chassis joints
• Coverage: Minimum 95% of ferrous metal surfaces below canopy
• Drying Time: 2–4 hours (ambient 25°C)
• Duration of Protection: Up to 6 months in enclosed or covered transport

3.2. Advantages:

• Non-toxic, biodegradable options available
• Self-healing film resists minor abrasion
• Compatible with pre-delivery washing and commissioning

3.3. Integration by Shipping Mode:

Method	Wax Spraying Compatibility	Additional Protection Measures

Bulk Cargo	Medium (limited post-stowage access)	Mandatory wax + shrink-wrapping on deck-stowed units
Flat Rack	High	Optional tarpaulin cover; recommended for tropical routes

---

4. Recommended Solution by Use Case

Scenario	Recommended Method	Rationale
Fleet Deployment (5+ units)	RO-RO	Fast turnaround, low damage rate, cost-efficient at scale
Remote Site Delivery (limited port access)	Flat Rack	Compatibility with break-bulk ports and inland crane logistics
Mixed Cargo Shipment (excavators + tools)	Flat Rack	Containerization enables consolidated LCL/ FCL shipping
Budget-Constrained (accepts higher risk)	Bulk Cargo (avoid if possible)	Only for obsolete or heavily depreciated units

---

5. Compliance & Documentation

All shipments must adhere to:
– IMSBC Code (for Bulk, if applicable)
– CTU (Cargo Transport Unit) Code for Flat Rack
– ISPS and SOLAS regulations
– COC (Certificate of Conformity) and export customs clearance from Chinese MOFCOM

Pre-shipment inspection (PSI) by third-party agency (e.g., SGS, BV) recommended for fleet buyers.

---

6. Conclusion

For reliable, scalable export of Yanmar excavators from China, RO-RO shipping with pre-shipment wax spraying offers the optimal balance of cost, speed, and equipment protection. Flat Rack is the preferred alternative for non-RO-RO destinations or mixed logistics. Bulk Cargo is not recommended for operational machinery due to elevated corrosion and damage risks.

Fleet managers should integrate wax corrosion protection into procurement contracts to ensure equipment readiness upon arrival.
