• Application Method: High-pressure spray (120–150 psi)
• Coverage Areas:
• Undercarriage (rollers, idlers, track links)
• Hydraulic cylinder rods
• Frame weld joints
• Electrical junction boxes (sealed post-treatment)
• Film Thickness: 30–50 µm (measured via wet-film gauge)
• Curing Time: 24 hours at 20°C prior to loading

4.2 Performance Metrics

Parameter	Specification
Salt Spray Resistance (ASTM B117)	>500 hours
Water Displacement	Complete within 1 hour of application
Repeatability	Single application sufficient for 45-day transit

Verification: Each unit undergoes post-treatment inspection with digital coating thickness measurement and visual audit.

---

5. Recommended Logistics Strategy

Scenario	Recommended Method	Rationale
Urgent delivery, >10 units	RO-RO	Fast turnaround, minimal handling damage
Cost-optimized, non-urgent	Bulk Cargo (with wax treatment)	Lowest cost; acceptable risk with corrosion control
High-value, precision units	Flat Rack + Weather Cover	Maximum protection, full visibility, secure lash

---

6. Compliance & Standards

All shipments comply with:
– IMO International Maritime Dangerous Goods (IMDG) Code (for fuel/lubricants)
– CSS Code (Cargo Securing on Vessels)
– ISO 1496/1 for Flat Rack container integrity
– Chinese Customs Export Classification: 8429.52.00 (Self-propelled excavators)

---

7. Conclusion

For Groundhog excavator exports from China, RO-RO and Flat Rack represent the optimal balance of cost, safety, and transit efficiency. Wax-based corrosion protection is non-negotiable for all sea shipments, with documented application required prior to vessel loading. Bulk cargo remains a viable option only under strict cost constraints and with enhanced protective measures.

Fleet managers and construction logistics teams are advised to integrate wax treatment into pre-shipment SOPs and prioritize containerized or RO-RO methods to ensure equipment readiness upon arrival.
