• Application Method: High-pressure electrostatic spray (25–35 µm thickness)
• Coverage Areas:
• Frame rails and crossmembers
• Fuel and air tanks
• Suspension brackets and leaf springs
• Exhaust system hangers
• Brake lines and electrical grounding points
• Performance Standard: 1,000+ hours salt fog resistance (ASTM B117)
• Reversibility: Non-hardening; removable via industrial steam or solvent wash pre-commissioning

Note: Wax protection is mandatory for all Bulk Cargo and Flat Rack shipments. RO-RO units receive partial application (undercarriage only), unless specified for extended lay-up.

4. Operational Recommendations by Use Case

Fleet Profile	Recommended Method	Rationale
Construction Fleets (50+ units, operational)	RO-RO	Fast discharge, minimal prep, low damage risk
Budget Rebuild Projects (non-running units)	Bulk Cargo	Lowest cost per unit; accepts higher risk
Oversized Articulated Trucks (e.g., crane carriers)	Flat Rack	Accommodates width/height beyond container limits
Mixed Fleet (Operational + Damaged)	Hybrid: RO-RO + Flat Rack	Segregate by condition; optimize cost and integrity

---

5. Compliance & Documentation

All shipments comply with:
– IMDG Code 2025 Edition (for residual fuel/battery hazards)
– CTU Code (Cargo Transport Unit) for lashing integrity
– China Customs Export Declaration (Form EX-7C) for used vehicle re-export
– Pre-shipment Inspection (PSI) per importing country requirements (e.g., EPA Section 601 for US-bound units)

---

6. Conclusion

For fleet managers and construction logistics planners, RO-RO shipping offers the optimal balance of protection, speed, and cost for drivable used trucks from Crookston, MN, exported via Chinese ports. Bulk Cargo remains viable for non-operational units where cost is paramount. Flat Rack is essential for non-standard dimensions but requires enhanced corrosion countermeasures.

SEA LION International’s wax-spray corrosion protection system is engineered to extend asset service life by up to 30% post-transit, reducing reconditioning costs and downtime.

Fleet deployment timelines should factor in port dwell time (avg. 72 hrs in Shanghai/Ningbo) and pre-loading preservation cycles (18–24 hrs for full wax cure).
