| High-volume fleet procurement | RO-RO + Wax Spray | Cost-efficient, faster turnaround, suitable for working units |
| Budget-constrained, inland destination | Avoid Bulk Cargo | High risk of claims; not cost-effective long-term |
| Arctic or tropical deployment | Flat Rack + Enhanced Wax | Extra coating zones (electrical enclosures, cab seals) |
6. Compliance & Documentation
All shipments must comply with:
– IMO International Maritime Solid Bulk Cargoes (IMSBC) Code (if applicable)
– CTU (Cargo Transport Unit) Code
– ISPM 15 for wooden dunnage (if used)
– Bill of Lading, Packing List, Certificate of Origin, Wax Treatment Certificate
7. Conclusion
For mini excavators sold by owner and exported from China, Flat Rack shipping with industrial wax corrosion protection offers the optimal balance of security, compliance, and long-term equipment integrity.
