Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared by: SEA LION International – Senior Engineering Division
Subject: Logistics Solutions for Exporting Small Excavators from China
Target Audience: Fleet Managers, Construction Equipment Procurement Officers, and Logistics Coordinators

Executive Summary

This report evaluates three primary maritime logistics methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of small excavators (operating weight: 1.5–6.0 tonnes) from manufacturing hubs in China (e.g., Xuzhou, Changsha, Qingdao) to global markets. The analysis compares cost efficiency, equipment integrity, transit time, and corrosion protection requirements, with emphasis on long-term durability in marine environments. Special attention is given to wax-based anti-corrosion treatments to mitigate seawater exposure risks.

---

2. Shipping Method Comparison

Criteria	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Loose Stowage)	Flat Rack Container (20’/40′)
Loading Mechanism	Self-propelled or towed onto vessel	Crane-lifted into hold	Crane-lifted onto open-sided platform
Stowage Density	High (efficient vertical stacking)	Low (requires dunnage & lashing)	Medium (1 unit per rack, stackable)
Transit Time	25–35 days (Asia to Europe/USA)	30–40 days	28–38 days
Port Infrastructure	Requires RO-RO terminal	Standard bulk terminal	Container terminal with heavy lift
Damage Risk	Low (minimal handling)	High (sway, impact, moisture)	Medium (exposed sides, weather risk)

Average Cost per Unit (USD)	$1,800–$2,400	$1,500–$2,000	$2,600–$3,200
Best Suited For	High-volume OEM shipments, operational units	Low-value, non-operational units	Oversized units, non-rollable models

---

3. Corrosion Protection: Wax Spraying Protocol

Marine transport exposes equipment to high-humidity, salt-laden air, and potential seawater ingress. To ensure long-term structural and functional integrity, wax-based anti-corrosion treatment is mandatory for all export-bound small excavators.

3.1 Wax Spraying Specifications

Parameter	Requirement
Wax Type	Solvent-based, hydrophobic polymer compound (e.g., DINITROL 4521, FUCHS Rustop)
Application Method	High-pressure spray (15–20 bar)
Coverage Areas	Undercarriage, boom/pin joints, hydraulic lines, chassis welds, radiator fins
Film Thickness	80–120 µm (dry)
Drying Time (Ambient)	4–6 hours
Salt Spray Resistance (ASTM B117)	>1,000 hours (no red rust)
Post-Transit Removal	Biodegradable solvent wash (recommended)

Note: Wax treatment must be applied post-final assembly and pre-containerization. Reapplication is advised if storage exceeds 60 days pre-shipment.

---

4. Method-Specific Risk Mitigation

Method	Corrosion Risk	Mitigation Strategy
RO-RO	Low–Medium	Wax spray + sealed cab, silica gel desiccants in operator compartment
Bulk Cargo	High	Full wax spray + VCI (Vapor Corrosion Inhibitor) bags in enclosed zones
Flat Rack	Medium–High	Wax spray + tarpaulin wrapping (PVC, UV-resistant) + corner protectors

---

5. Recommendations

• For High-Volume OEM Exports: Use RO-RO for cost-per-unit efficiency and reduced handling damage. Ideal for operational units destined for immediate deployment.
• For Budget-Conscious Buyers: Bulk Cargo offers lower freight costs but requires enhanced corrosion protection and post-arrival reconditioning.
• For Non-Standard or Damaged Units: Flat Rack provides flexibility for units that cannot be driven or exceed container dimensions.

Critical Note: Regardless of shipping method, wax spraying is non-negotiable for equipment longevity. SEA LION International mandates compliance with ISO 9227 (corrosion testing) for all export shipments.

---

6. Conclusion

Optimal logistics selection depends on shipment volume, equipment condition, destination infrastructure, and lifecycle cost considerations. While RO-RO offers the best balance of cost and protection for standard small excavators, Flat Rack and Bulk Cargo remain viable for niche cases—provided anti-corrosion protocols, especially industrial-grade wax spraying, are strictly enforced.

SEA LION International continues to support clients with integrated logistics packages, including pre-shipment inspection, wax application certification, and marine insurance coordination.
