4. Corrosion Protection: Wax Spraying Protocol

Compact excavator attachments are highly susceptible to saltwater-induced corrosion during maritime transit. To mitigate degradation, SEA LION International recommends the Industrial Wax Spraying (IWS) Protocol, applied pre-shipment at certified Chinese packaging facilities.

IWS Protocol Specifications:

Parameter	Specification
Wax Type	Solvent-based, hydrophobic synthetic resin (e.g., VCI-7000 series)
Application Method	Electrostatic spray coating (8–12 μm thickness)
Coverage Areas	All machined surfaces, hinge points, hydraulic ports, threaded zones
Drying Time	30–45 minutes at 25°C
Protection Duration	Up to 12 months in marine environments
Removal Process	Biodegradable citrus-based solvent; non-abrasive
Compliance	ISO 9227 (salt spray testing), MIL-PRF-16173G (Grade 2)

Note: Wax spraying is strongly advised for all shipments, but most effective under Flat Rack or enclosed RO-RO deck conditions. Bulk cargo renders wax protection partially ineffective due to abrasion and moisture saturation.

---

5. Recommended Solution by Use Case

Customer Profile	Recommended Method	Rationale
High-Value, Precision Attachments (e.g., tilt rotators)	Flat Rack Container + IWS	Maximum protection, traceability, and integrity assurance
High-Volume, Simple Attachments (e.g., buckets, couplers)	RO-RO + IWS	Cost-effective for batches; faster turnaround at compatible ports
Budget-Constrained, Non-Critical Components	Bulk Cargo (only if integrated with raw steel shipments)	Risk of damage and corrosion not recommended for standalone exports

---

6. Conclusion

For reliable, industrial-grade export logistics of compact excavator attachments from China, Flat Rack container shipping combined with Industrial Wax Spraying offers the optimal balance of protection, traceability, and global accessibility. RO-RO is viable for mobile or high-volume units destined to RO-RO-capable ports. Bulk Cargo is not recommended due to unacceptably high corrosion and damage risks, especially for precision equipment.

SEA LION International advises integration of the IWS Protocol across all shipment types to comply with ISO durability standards and reduce field failure rates upon delivery.
