---

2. Technical Evaluation by Modality

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

• Advantages:
• Minimal handling reduces mechanical stress.
• Fast loading/unloading via ramps.
• Ideal for operational or semi-assembled Hitachi ZX-series units.
• Limitations:
• Limited availability of RO-RO terminals outside major hubs (e.g., Shanghai, Rotterdam).
• Higher exposure to salt spray unless enclosed in weatherproof wraps.
• Not suitable for loose or small components.

Corrosion Mitigation: Apply industrial-grade wax emulsion spray (e.g., Cosmoline C5 or equivalent) to exposed hydraulic cylinders, pivot joints, and unpainted metal surfaces prior to transit. Wax film thickness: 25–50 µm. Reapplication recommended upon arrival.

---

2.2 Bulk Cargo

• Advantages:
• Lowest cost per ton for raw or machined parts (e.g., bucket teeth, track links).
• High volume capacity.
• Limitations:
• High risk of seawater ingress and condensation in hold areas.
• Part-on-part abrasion leads to surface degradation.
• No individual part traceability; unsuitable for precision components.

Corrosion Mitigation: Bulk loads must be double-wrapped in VCI (Vapor Corrosion Inhibitor) kraft paper and placed in sealed HDPE liners. Wax spraying not recommended due to particulate contamination risk. Desiccant packs required at 500g per m³.

---

2.3 Flat Rack Containers (20′ & 40′)

• Advantages:
• Full structural support with lashing points (ISO 1496/3 compliant).
• Accommodates oversized components (e.g., dipper arms up to 12m).
• Weather protection via tarpaulin or container-side enclosure.
• Compatible with multimodal interchanges (rail, truck, port crane).
• Limitations:
• Higher per-unit cost than bulk.
• Requires skilled rigging for securement.

Corrosion Mitigation: Electrostatic wax spraying (paraffin-based, salt-exclusion formula) applied pre-loading. Coverage must include weld zones and machined surfaces. Post-spray inspection via wet film thickness gauge (ASTM D4414). Treated parts to be stored >24h before shipment to ensure cure.

---

3. Corrosion Protection Protocol: Wax Spraying Specification

All Hitachi excavator parts exposed to marine environments must undergo passive corrosion protection in accordance with ISO 9223 (C3-C5 corrosivity categories).
