Shippers Own Containers (SOC): The Complete Guide

What is a Shipper’s Own Container?

A Shipper’s Own Container (SOC) is a freight container owned by the exporter, importer, freight forwarder, or cargo owner rather than the shipping line. The shipping line simply transports the equipment after accepting the booking, while ownership and ongoing responsibility remain with the shipper.

SOC containers have become increasingly popular across international logistics due to recurring equipment shortages, rising detention charges, and the need for greater flexibility in supply chains. They are commonly used by construction companies, exporters, manufacturers, project logistics specialists, military contractors, charities, and organisations that transport cargo to remote destinations.

Common Types of SOC Containers

Compliance Responsibilities

Ownership of an SOC places several important legal responsibilities upon the container owner. International shipments are governed by numerous conventions, customs regulations and carrier operating procedures. Before presenting an SOC for export, owners should ensure that all applicable documentation and inspections have been completed.

Typical SOC Shipping Process

1. Purchase or lease a compliant ISO shipping container.
2. Verify structural integrity and CSC certification.
3. Book a shipment with a carrier that accepts SOC equipment.
4. Load and secure cargo correctly.
5. Declare the Verified Gross Mass (VGM).
6. Complete customs documentation.
7. Deliver the container to the export terminal.
8. Transport internationally.
9. Reuse, retain or reposition the container after delivery.
