CSC Plate Information: What It Means and Why It Matters

What Is a CSC Plate?

CSC stands for Container Safety Convention, an international agreement created in 1972 by the United Nations and the International Maritime Organisation (IMO). The CSC plate, also called a CSC panel, is a mandatory, standardised metal plate fixed to a container’s exterior, usually on the left door, confirming that the container meets stringent safety and performance standards.

Why Are CSC Plates Important?

The CSC plate certifies that a container is structurally sound for cargo transportation. Without it, containers can be rejected at ports or by shipping lines. It ensures the safety of dockworkers, freight handlers, and cargo. Much like a car’s MOT, regular inspections renew the certification and extend the container’s usability for international shipping.

What Information Does a CSC Plate Display?

A valid CSC plate typically includes:

• Container model type – design specification reference
• CSC rules version – under which the container was approved
• Manufacturer’s serial number
• Container identification number – usually includes an owner code and serial number.
• Manufacturer's name and address
• Date of manufacture
• Timber treatment details – treatment of any wooden floor components
• Classification society approval number
• Maximum gross weight – total safe loaded weight
• Allowable stacking weight for 1.8G forces
• First maintenance examination date
• Racking test load value – the amount of side-to-side force the container frame can handle

CSC Plate Design Requirements

The construction and appearance of a CSC plate must follow strict guidelines:

• Fabricated from non-corrosive, fire-resistant material
• Minimum size: 20cm x 10cm
• Text height: 8mm for "CSC SAFETY APPROVAL", 5mm for all other information
• Lettering must be embossed or stamped and highly legible
• Contrast in colour from the container to ensure visibility

These rules ensure the plate remains readable throughout the container’s service life, even in harsh conditions.

What Happens If a Container Has No Valid CSC Plate?

A container without a valid CSC plate cannot legally be used for international shipping. Customs may reject it, refused by shipping lines, and pose safety risks. CSC certification ensures containers are fit for purpose and helps avoid costly delays, refusals, or insurance issues.

Suppose a container's CSC plate is missing or expired. In that case, it must undergo inspection and certification by approved bodies such as Bureau Veritas or the International Institute of Container Lessors (IICL) to regain compliance.

How to Check a CSC Plate

Before purchasing or leasing a container, always verify the CSC plate. Confirm:

• The plate is physically present and securely attached
• Information is legible and matches the container documentation
• The latest inspection date is valid

If in doubt, request a recertification before finalising your purchase.
