|---|---|---|
| High-Volume Fleet Export (10+ units) | RO-RO | Cost-efficient, rapid turnaround at RO-RO-capable ports |
| Single Unit to Harsh Climate (e.g., Middle East, Coastal Africa) | Flat Rack + Wax | Maximum protection, traceability, reduced condensation risk |
| Budget-Constrained Project, Non-Critical Timeline | Bulk Cargo | Lowest cost; acceptable with full wax + desiccant bags |
| Machinery with Sensitive Hydraulics | Flat Rack | Isolated stowage prevents vibration damage |
6. Compliance & Documentation
All shipments must comply with:
– IMDG Code (for wax solvents, if classified)
– CSS Code (Cargo Securing Manual per ISO 1161)
– CIQS (China Entry-Exit Inspection and Quarantine)
– Bill of Lading, Packing List, and Certificate of Origin
7. Conclusion
For optimal balance of cost, protection, and logistics efficiency in exporting CAT 320-class excavators from China:
– RO-RO is ideal for volume and speed but requires supplemental wax protection.
– Bulk Cargo offers lowest cost but highest risk; only recommended with full corrosion mitigation.
– Flat Rack provides superior asset protection and is strongly advised for high-value or long-transit shipments.
Implementing standardized wax spraying protocols reduces post-arrival maintenance costs by up to 40% and extends equipment service life in corrosive environments.
