4. Corrosion Protection: Wax Spraying Protocol

Seawater exposure during transit poses a high risk of corrosion to hydraulic components, undercarriage rollers, and structural steel. SEA LION International mandates the following anti-corrosion procedure for all JD 50 exports:

Wax-Based Protection System (WBPS-2026)

Component Protected	Treatment Method	Coating Thickness	Duration (Protection)
Undercarriage Assembly	High-pressure wax spray (cavity protection)	25–30 µm	Up to 6 months
Hydraulic Cylinders	Internal fogging + external wax sealant	20 µm	4–6 months
Electrical Enclosures	Dielectric wax spray (non-conductive)	15 µm	3–4 months
Exposed Fasteners & Joints	Penetrating corrosion inhibitor + wax topcoat	35 µm	6+ months

Application Standard:
– Performed in climate-controlled facility pre-loading
– ASTM D1141 synthetic seawater tested
– Compliant with ISO 9227 salt spray testing (1,000 hrs pass)

---

5. Recommended Shipping Strategy

Scenario	Recommended Method	Rationale
Exporting 10+ units to Mediterranean	RO-RO	Cost/unit drops with volume; faster discharge
Single unit to West Africa (limited RO-RO)	Flat Rack	Wider port compatibility; secure lashing
Non-functional unit (reconditioning)	Bulk Cargo	Lowest cost; damage risk acceptable

---

6. Compliance & Documentation

All shipments must include:
– Bill of Lading (B/L)
– Certificate of Origin (China CO)
– Equipment Test Report (ETR) – post-wax inspection
– Packing List with corrosion treatment log
– IMDG Code compliance (if fuel residues present)

---

7. Conclusion

For fleet managers and construction firms deploying JD 50 excavators globally, RO-RO shipping from Chinese ports offers the optimal balance of cost, speed, and equipment safety. Flat Rack is viable for niche routes, while Bulk Cargo is discouraged for operational units due to high damage risk. Wax-based corrosion protection is non-negotiable for all sea exports and must be documented per WBPS-2026 standards.

Future logistics planning should integrate port readiness assessments and pre-treatment verification to ensure equipment arrives operational and within warranty compliance.
