4. Corrosion Protection: Wax Spraying Protocol

Seawater exposure during ocean transit poses a significant risk to excavator integrity, particularly in high-humidity and salt-laden environments. SEA LION International mandates the application of industrial-grade anti-corrosion wax as a standard protective measure for all exported 325 excavators.

Wax Spraying Specifications:

Parameter	Specification
Wax Type	Solvent-based, hydrophobic polymer blend
Application Method	High-pressure spray + brush detailing
Coverage Areas	Undercarriage, track links, pins, boom joints, hydraulic cylinder rods, radiator fins
Film Thickness	50–75 µm (dry)
Salt Spray Resistance	ASTM B117 compliant (1,000+ hours)
Post-Transit Removal	Biodegradable solvent wash or steam cleaning

Note: Wax application must occur within 48 hours of final assembly and prior to inland transport to port. Reapplication is advised if transit exceeds 45 days or includes tropical monsoon zones.

---

5. Risk Assessment & Recommendations

Risk Factor	RO-RO	Bulk Cargo	Flat Rack
Corrosion Exposure	Low	High	High
Physical Impact Risk	Low	High	Medium
Weather Exposure	Partial	Full	Full
Port Delays (Handling)	Low	Medium	Medium
Customs Clearance Speed	Fast	Moderate	Moderate

Recommended Use Cases:

• RO-RO: Preferred for operational machines, time-sensitive deliveries, and high-volume fleet exports.
• Bulk Cargo: Cost-effective for non-functional units or major overhauls; requires enhanced dunnage and corrosion control.
• Flat Rack: Ideal when disassembled (e.g., boom removal), or when destination lacks RO-RO infrastructure.

---

6. Compliance & Documentation

All shipments must comply with:
– IMDG Code (for ancillary fuels/lubricants)
– China Export Control Regulations (CCMC certification)
– Destination country import standards (e.g., CE, EPA Tier 4 Final)
– Bill of Lading, Packing List, Commercial Invoice, Certificate of Origin

---

7. Conclusion

For the export of the ‘325 Excavator’ from China, RO-RO shipping offers optimal balance of protection, speed, and cost for operational units. Bulk Cargo is viable for cost-driven, non-operational shipments but demands rigorous corrosion and lashing protocols. Flat Rack provides flexibility for oversized configurations but increases exposure risk. Industrial wax spraying is non-negotiable across all methods to ensure equipment integrity upon delivery.

SEA LION International recommends RO-RO as the default solution, supplemented by wax protection and real-time GPS tracking for high-value fleet consignments.
