---

2. Technical Evaluation by Method

2.1 RO-RO (Roll-on/Roll-off)

• Advantages:
• Fast loading/unloading using ramps; minimal handling reduces mechanical stress.
• Vehicles remain operational upon arrival; no reassembly required.
• Optimized for high-volume tractor truck exports.

• Lower labor and crane dependency.

• Disadvantages:

• Limited to ports with RO-RO infrastructure (e.g., Antwerp, Houston, Jebel Ali).
• Exposure to salt spray unless enclosed or sealed.

• Risk of deck-level flooding in rough seas if drainage fails.

• Corrosion Protection:

• Wax spraying (see Section 4) is critical due to open deck exposure.
• Interior cabin and undercarriage fogging recommended.

---

2.2 Bulk Cargo (Loose Stowage)

• Advantages:
• Suitable for non-operational units or damaged units requiring repair post-arrival.

• Flexible in port selection (most general cargo ports accept bulk).

• Disadvantages:

• High handling risk during crane lifts; potential for frame or component damage.
• Extended port dwell time increases exposure to coastal humidity.

• No standardized securing; prone to shifting in heavy seas.

• Corrosion Protection:

• Full wax encapsulation required due to prolonged exposure during loading and stowage.
• Desiccant bags inside cabins and sealed electrical enclosures advised.

---

2.3 Flat Rack Container

• Advantages:
• Secure, standardized ISO container handling.
• Stackable; compatible with global intermodal networks (rail, truck, ship).

• Partial weather shielding; tarpaulin or shrink-wrapping enhances protection.

• Disadvantages:

• High cost per unit; limited availability on high-demand trade lanes.
• Requires disassembly of oversized components (e.g., extendable hitches).

• Crane access needed at both ends.

• Corrosion Protection:

• Wax spray + breathable moisture barrier film (e.g., VCI paper) recommended.
• Ideal for long-term storage-in-transit due to reduced condensation risk.

---

4. Wax Spraying for Seawater Corrosion Protection

To mitigate saltwater-induced degradation during maritime transport, SEA LION International mandates the application of industrial-grade rust-inhibiting wax emulsion on all HOWO NX Tractor Trucks prior to shipment.

Specifications:

• Product Type: Solvent-based, hydrophobic wax (e.g., DINITROL 45xx series or equivalent)
• Application Method: High-pressure spray (12–15 bar)
• Coverage Areas:
• Undercarriage (frame rails, suspension, exhaust)
• Wheel hubs and brake assemblies
• Engine bay (external surfaces)
• Exposed fasteners and hinge points

Performance Metrics:

Parameter	Value
Salt Spray Resistance (ASTM B117)	≥ 500 hours
Film Thickness	30–50 μm
Service Temperature Range	-30°C to +80°C
Repeatability	Single application sufficient for 45-day voyage

Note: Wax film must remain intact until post-delivery inspection. Removal should be conducted using biodegradable degreasers prior to commissioning.

---

5. Recommendations

Use Case	Recommended Method	Rationale
High-volume fleet delivery (≥50 units)	RO-RO + Wax Spray	Cost-effective, rapid turnaround
Remote site delivery with limited port access	Flat Rack + VCI Wrapping	Maximum protection and intermodal flexibility
Non-operational or salvage units	Bulk Cargo + Full Encapsulation	Lower cost tolerance, higher risk acceptance

---

6. Conclusion

For fleet managers and construction logistics planners, RO-RO shipping offers the optimal balance of cost, speed, and integrity for HOWO NX Tractor Truck exports from China. However, when maximum corrosion resistance and handling control are required—particularly in tropical or high-humidity routes—Flat Rack with industrial wax protection is the preferred solution. Bulk Cargo remains a fallback option for non-critical or repair-bound units.

All export shipments should include standardized wax-based anti-corrosion treatment compliant with ISO 9227 and ASTM D1748 marine exposure protocols.
