Corrosion	Medium (exposed decks)	Low (enclosed hold)	High (full exposure)
Physical Damage	Low	High	Medium
Theft/Vandalism	Low	Medium	Medium
Weather Delays	Low	Medium	Medium
Mitigation Strategy	Wax spray + sealed cab	Wax spray + wooden crating	Wax spray + tarpaulin + lashing

---

6. Recommended Logistics Strategy

Destination Region	Preferred Method	Rationale
Middle East / Africa	RO-RO	High port compatibility, low handling risk, cost efficiency
South Asia / Oceania	RO-RO or Flat Rack	RO-RO where available; Flat Rack for remote ports
Latin America	RO-RO	Extensive RO-RO coverage via COSCO, Hapag-Lloyd routes
Landlocked Regions	Flat Rack	Enables rail/truck intermodal transfer
Cost-Sensitive Markets	Bulk Cargo (discouraged)	Only if no alternative; high damage rate observed in 2025 audits

Note: SEA LION does not recommend bulk cargo for high-value excavators due to 18.3% incident rate (2025 data) involving hydraulic leaks and track misalignment.

---

7. Compliance & Documentation

All shipments must include:
– Bill of Lading (Sea Waybill)
– Certificate of Origin (China CO)
– Pre-shipment Inspection (PSI) report
– Wax treatment certification (ISO 9227 compliance)
– DG Declaration (if hydraulic fluid exceeds limits)

---

8. Conclusion

For the export of 306 Cat Excavators from China in 2026, RO-RO shipping offers the optimal balance of safety, speed, and cost for most global destinations. Flat Rack remains a viable alternative for non-RO-RO ports, while Bulk Cargo is discouraged due to elevated equipment risk.

Mandatory wax-based anti-corrosion treatment is critical across all methods. SEA LION International advises fleet managers to integrate wax spraying into pre-shipment protocols at origin to ensure machinery arrives in operational condition, minimizing post-delivery rework and warranty claims.
