Shipper Owned Container (SOC): Definition, Types, and Advantages
Compared to Carrier Owned Containers (COC), a Shipper Owned Container (SOC) gives businesses greater control and flexibility over their shipping needs. Since these SOC containers are purchased or leased by the company itself, businesses can manage container ownership independently without relying solely on shipping lines.
In recent years, the use of SOC containers has grown significantly. More companies are now looking for ways to optimize global trade, and studies show that over 35% of businesses report lower shipping costs and improved cargo flow efficiency after switching to SOC.
In this blog, I will explain what a Shipper Owned Container is, the different types available, and why it plays such an important role in logistics.
What is a Shipper Owned Container (SOC)?
A Shipper Owned Container (SOC) is a cargo container that belongs to the shipper or freight forwarder instead of the carrier. By using SOC containers, businesses can take full control of their logistics and avoid additional charges often associated with Carrier Owned Containers (COC).
This flexibility is especially valuable when companies handle long-haul shipments or frequently encounter delays. Moreover, SOC containers are often stored at ports, warehouses, and remote locations, making them an ideal solution for both domestic and international shipping.
Types of Shipper Owned Containers
Different types of SOC containers are available to meet varying business needs. The right choice depends on factors such as cargo type, destination, and transport environment.
Standard SOC Containers
These are the most common containers, mainly used for general cargo transport. Industries like manufacturing, retail, and agriculture widely rely on them for safe storage and shipping.
Specialized SOC Containers
Specialized SOCs, such as refrigerated containers and open-top containers, are designed for temperature-sensitive or oversized goods. These are widely used in food logistics, pharmaceuticals, and construction.
High-Cube SOC Containers
High-cube containers are taller than standard ones and provide more capacity. They are especially suitable for large equipment or bulky cargo. Many retailers and industrial companies use them to improve shipping efficiency.
Flat-Rack SOC Containers
Flat-rack containers have collapsible sides, making them perfect for transporting heavy machinery, vehicles, and oversized industrial equipment. Industries like mining and construction often rely on these versatile SOC containers.
Shipper Owned Container (SOC) vs. Carrier Owned Container (COC)
The main difference between Shipper Owned Containers (SOC) and Carrier Owned Containers (COC) is ownership. SOC containers belong to the business, giving it more control and reducing dependency on carriers. This also helps avoid charges such as demurrage and detention fees.
In contrast, COC containers belong to shipping lines. If shippers fail to return empty COCs on time, they often face extra fees. As a result, SOC containers allow freight forwarders to manage transportation more efficiently, while COCs limit flexibility due to carrier schedules and possible delays.
Key Advantages of Shipper Owned Containers
Using SOC containers provides several benefits, especially for international trade and long-term logistics planning:
Cost Management: SOC containers reduce costs by avoiding demurrage and detention fees linked with COCs.
Flexibility: Businesses can choose carriers freely, manage schedules better, and maintain control over cargo flow.
Logistics Control: Companies gain greater control over their supply chain, reducing risks of port congestion or carrier-related delays.
Additional Storage: SOC containers can double as mobile storage units, particularly in remote areas.
Versatility: These containers serve multiple purposes, from long-haul transport to on-site storage in industries like construction and retail.
In short, investing in Shipper Owned Containers offers flexibility, control, and cost savings that help businesses streamline their shipping operations.
Cost Considerations for SOC Containers
Purchasing a Shipper Owned Container (SOC) requires an upfront investment, as businesses must buy or lease the container. The cost depends on the condition and size of the unit. Maintenance is another factor since the owner is responsible for inspections and repairs.
While detention charges can still occur if shipping delays happen, SOC containers avoid demurrage fees, making them more cost-effective compared to COCs.
How to Acquire Shipper Owned Containers
Companies can obtain SOC containers either through purchase or leasing.
Purchase: Businesses can buy directly from shipping lines, leasing companies, or second-hand suppliers. It is essential to verify the container’s serial number, condition, and ensure it has a valid CSC plate for international use.
Lease: Leasing SOC containers provides flexibility for short-term needs with lower upfront costs. However, extra charges may apply.
Regardless of purchase or lease, always verify container ownership and check that the SOC is suitable for long-distance transport.
Steps to Acquire SOC Containers
- Research Suppliers – Look for reliable shipping lines, leasing companies, or resellers.
- Inspect Containers – Check for wear and tear, valid CSC certification, and container numbers.
- Decide on Purchase or Lease – Match your choice with long-term or short-term business needs.
- Verify Ownership – Confirm that the seller legally owns the SOC container.
- Check Specifications – Ensure the container fits your specific cargo requirements.
Managing Shipper Owned Containers
Proper management ensures smooth operations and minimizes logistics challenges. Businesses must track, maintain, and comply with regulations to keep SOC containers in optimal condition.
Inventory Management: Use software tools to track container movement, avoid loss, and ensure efficient cargo flow.
Maintenance & Inspection: Conduct regular inspections to keep SOC containers compliant with safety standards.
Legal Compliance: Follow International Maritime Organization (IMO) regulations and ensure containers hold valid CSC plates.
Common Challenges and Solutions
Like any logistics solution, Shipper Owned Containers come with challenges. Below are some common issues and how to address them:
Customs Handling: Delays may occur during clearance. Ensure proper documentation and work with experienced freight forwarders.
Tracking Container Numbers: Monitoring large fleets can be complex. Automated software helps minimize errors.
Responsibility & Maintenance: Since the shipper owns the container, maintenance responsibility lies with them. Outsourcing repairs or using digital tracking tools can ease this burden.
Conclusion
Understanding the value of a Shipper Owned Container (SOC) helps businesses gain stronger control over logistics, lower costs, and optimize supply chain efficiency. Compared to Carrier Owned Containers (COC), SOC containers provide flexibility and independence that benefit long-term international trade operations.
Whether purchased or leased, SOC containers remain a smart and cost-effective choice for companies aiming to simplify transportation and strengthen their logistics management.
By using Shipper Owned Containers, you can confidently streamline your shipping process, reduce expenses, and achieve better supply chain control.
