|---|---|---|---|
| Seawater Corrosion | Medium | High | Medium |
| Physical Impact | Low | High | Medium |
| Moisture Ingress (Cab/Electrical) | Medium | High | Low |
| Delayed Unloading | Low | Medium | Medium |
| Theft/Vandalism | Low | Medium | Low (if sealed) |
Recommendations
-
Preferred Method – Flat Rack:
Recommended for high-value contracts, remote destinations, and units with sensitive electronics. Offers maximum protection, full inspection access, and compatibility with wax sealing and tarpaulin covering. -
Cost-Effective Alternative – RO-RO:
Suitable for nearby regions with RO-RO infrastructure. Requires strict adherence to wax spraying and pre-shipment inspection. -
Avoid – Bulk Cargo:
Not recommended for 336 excavators due to high risk of corrosion and handling damage. Only viable under tight budget constraints with full insurance coverage.
Conclusion
For reliable and industrial-grade export logistics of the 336 excavator from China, Flat Rack shipping with synthetic wax corrosion protection provides the optimal balance of safety, compliance, and long-term equipment integrity. RO-RO remains a viable secondary option for proximate markets. Bulk Cargo is discouraged unless no alternative exists.
SEA LION International enforces a zero-tolerance policy for non-compliant anti-corrosion treatment. All units must pass pre-shipment inspection with documented wax application logs.
