Executive Summary

This report evaluates three primary maritime shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container transport—for the export of excavator mulchers from manufacturing hubs in China to global project sites. The analysis focuses on cost efficiency, equipment protection, transit reliability, and corrosion mitigation, with specific reference to the application of wax-based anti-corrosion treatments during marine transit.

---

1. Equipment Overview: Excavator Mulcher

Excavator mulchers are heavy-duty forestry and land-clearing attachments mounted on excavator carriers. Key characteristics influencing shipping logistics:

• Weight: 8–25 metric tons (unit-dependent)
• Dimensions: Up to 4.5 m (L) × 3.2 m (W) × 3.8 m (H)
• Sensitive Components: Hydraulic systems, cutting drums, control panels
• Corrosion Risk: High exposure to salt-laden atmospheres during sea transit

---

Insurance Premium	Moderate	High	Low to Moderate
Suitability for Mulchers	High (if self-propelled)	Low (poor protection)	Very High (optimal for oversized)

---

3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose metal surfaces to chloride-induced corrosion. To mitigate degradation during transit (typically 14–35 days), SEA LION International mandates the application of industrial-grade wax-based corrosion inhibitors prior to shipment.

Wax Spraying Specifications:

Parameter	Requirement
Coating Type	Solvent-based synthetic wax (e.g., DINITROL 4600)
Application Method	High-pressure spray (minimum 25 psi)
Coverage Areas	Undercarriage, hydraulic cylinders, joints, unpainted steel
Film Thickness	30–50 µm (uniform layer)
Drying Time	4–6 hours at 25°C ambient
Salt Spray Resistance	>500 hours (ASTM B117 compliant)
Post-Transit Removal	Biodegradable solvent wash or steam cleaning

Note: Wax protection is recommended for all shipping methods but is critical for RO-RO and Bulk Cargo due to direct seawater spray exposure.

---

4. Method-Specific Recommendations

RO-RO Shipping

• Best for: Operational units capable of self-propulsion.
• Advantages: Fast loading/unloading; reduced crane dependency.
• Limitations: Limited port availability; higher exposure to salt spray.
• Mitigation: Full wax spray + temporary plastic shielding of cab and hydraulics.

Bulk Cargo

• Best for: Cost-sensitive, non-urgent shipments of multiple units.
• Advantages: Lowest freight cost per ton.
• Limitations: High risk of impact damage; no environmental protection.
• Mitigation: Wax spray + wooden crating of sensitive zones; avoid in high-humidity routes.

Flat Rack Container

• Best for: High-value or precision mulcher units; long-distance exports.
• Advantages: Full lashing capability; tarpaulin coverage; ISO container tracking.
• Limitations: Higher cost; requires port crane availability.
• Mitigation: Wax spray + desiccant bags inside enclosed tarp system; GPS shock monitoring.

---

5. SEA LION International Compliance Standards

All export shipments from Chinese facilities (Shanghai, Qingdao, Nansha) must comply with:

• ISO 1496/3 – Flat Rack Container Safety
• CTU Code (IMO/ILO/UNECE) – Cargo Transport Unit guidelines
• IMDG Code (for ancillary fluids) – Hydraulic oil and fuel handling
• Internal Specification SL-MUL-2026-CORR – Mandatory wax corrosion protection

---

6. Conclusion & Recommendations

For excavator mulcher exports from China, Flat Rack container shipping is recommended for high-value or long-transit shipments due to superior protection and traceability. RO-RO is viable for operational units moving to RO-RO-equipped ports, provided wax protection and tarping are applied. Bulk Cargo is discouraged except for budget-constrained, short-sea routes with minimal exposure.

Universal Requirement: Application of industrial wax spray per SL-MUL-2026-CORR is mandatory across all methods to ensure equipment integrity upon delivery.
