What is a container CSC plate and why should we check it before shipping?

When buying, renting or loading a shipping container, it is not enough to check the appearance of the hull. One of the most important things to see on containers used in international shipping is the CSC Plate or Container Safety Certification Plate.

When buying, renting or loading a shipping container, it is not enough to check the appearance of the hull. One of the most important things to see on containers used in international shipping is the CSC Plate or Container Safety Certification Plate.

What is CSC Plate?

After a Container Design has been approved according to the relevant requirements, the competent authority or authorized organization can issue permission to install a Safety Approval Plate.

This plate indicates that the container design has been approved for its intended use in accordance with the CSC framework. One of the important principles of the Convention is the mutual acceptance of these approvals between member countries so that approved containers can be transported in international transport with minimal additional safety formalities.

Does having a CSC license plate mean the container is always safe?

No; and this point is very important when buying a used container.

CSC is not limited to initial design approval. Subsequent maintenance of the container is the responsibility of the Owner and the container must undergo the necessary inspections.

So the presence of an old license plate on the body does not replace checking the current condition of the floor, corner fittings, doors, walls, ceiling, corrosion, and structural deformation.

What kind of information is on a CSC license plate?

The safety plate provides information about the approval and key safety features of the container, including specifications related to the approval, production, and design capacities of the container.

As a result, when inspecting a container, the plate information must match the container itself, and any illegibility, tampering, or significant discrepancies must be taken seriously.

What does CSC have to do with container weight?

The two concepts should not be confused:

• The CSC Plate is about the approval and safety capacities of the container structure.
• VGM is the actual gross weight of the container after loading for a specific shipment.

So even if the CSC specification indicates that the container is designed for a certain Maximum Gross Mass, the shipper must still declare the actual weight of the loaded container in accordance with VGM requirements. This, along with proper stowage and securing of the container, is part of controlling shipping risk.

How is a periodic container inspection carried out?

The CSC Convention has considered the issue of Examination for the continued safe use of Containers.

In practice, containers may be subject to inspection and control programs. The goal is that a container that has worked for years in harsh port, sea and land conditions should not be assumed safe solely based on its condition at the time of manufacture.

For this reason, when buying or renting a container, in addition to the year of construction, it is best to check the repair records, structural condition, and examination information.

The Iranian Ports and Maritime Organization has also included the “International Convention on Safe Containers CSC 1972” in its set of regulations and circulars.

What should we check besides CSC when buying a used container?

• Corrosion status of columns and beams and health of corner castings
• Container floor and signs of rot or water infiltration
• Sealing, locks, and proper door operation
• Repair work, serious dents or structural deformation
• Container inspection and previous use records

The intended use is also important. A container that is intended to be used solely as a fixed storage facility does not have the same requirements as a container that is to be used in international shipping.

Why is CSC important for product owners?

The owner of the goods may not own the container, but choosing the wrong equipment directly puts her cargo at risk.

Even the best packaging cannot eliminate all risks if the container floor is damaged, the doors do not close properly, or the structural components are faulty. This is why container inspection before stuffing should be part of the shipping quality control process.

Is CSC also important for rental containers?

Yes. If the container is to be used in international shipping, being rented does not eliminate safety issues.

Before delivering the container, it is best to inform the supplier of your intended use and ensure that the equipment is suitable for that operation.

Conclusion

The CSC Plate can be considered one of the important container safety identification cards, but it should not be confused with the current health guarantee of the container.

Before shipping, purchasing or leasing a container, both the CSC information and status and the actual condition of the container body and structure must be checked. In addition, the actual cargo weight and VGM requirements must also be considered separately.

FAQ

What does CSC stand for?
International Convention for Safe Containers.

Is the CSC Plate the same as the VGM?
No. CSC is about container safety and verification; VGM is the verified gross weight of the container after loading.

Who is responsible for maintaining the approved container?
As explained by IMO, it is the responsibility of the Owner to maintain the Container further.

Is CSC also relevant in Iran?
Yes. The Ports and Maritime Organization has CSC 1972 in its set of regulations.
