CSC Plate & Container Certification: What Buyers Need to Know
What the CSC plate is, why it matters, and how container certification works when buying in Saudi Arabia — reading the plate, ACEP/PES re-inspection, and when you do and don't need it.
Quick answer
The CSC plate (Safety Approval Plate) is a metal plate on a container's door certifying it meets the International Convention for Safe Containers. It records the unit's data and re-inspection status. A valid CSC plate is required to ship a container by sea, but not for static storage, offices or conversions.
Key takeaways
- The CSC plate certifies a container is structurally safe to handle and stack when shipping by sea.
- A valid plate is required for export shipping — but not for storage, offices or conversions.
- Certification is kept current by periodic re-inspection under an ACEP or PES scheme.
- Always record the container's serial number and CSC details when you buy.
Every genuine shipping container carries a small metal plate on its left-hand door — the CSC plate, or Safety Approval Plate. It is one of the first things our surveyors check and one of the most misunderstood details by buyers. This guide explains what the plate certifies, how to read it, and when it actually matters for your purchase.
What is the CSC plate?
CSC stands for the International Convention for Safe Containers, an International Maritime Organization treaty that sets safety standards for containers in international transport. The CSC plate is the certificate that a specific container was approved as structurally safe to lift, stack and carry cargo. Without a valid plate, a container cannot legally be shipped by sea — ports and lines will refuse it.
How to read a CSC plate
The plate is stamped with the container's key data. The most important fields for a buyer are below.
| Field | What it tells you |
|---|---|
| Date manufactured | The container's build date — a guide to its age |
| Identification (serial) number | The unique owner/ISO code for this exact unit |
| Maximum gross weight | Total laden weight the unit is rated for |
| Allowable stacking weight | How much can be stacked on top at sea |
| Racking test value | Structural strength the unit was tested to |
| Next examination date / ACEP | When re-inspection is due, or the ACEP scheme it is under |
Keeping certification current: ACEP and PES
A one-off approval is not enough — containers in service must be re-examined periodically. There are two schemes. Under the Periodic Examination Scheme (PES), each unit is inspected at set intervals and the next date is marked on the plate. Under the Approved Continuous Examination Programme (ACEP), the owner runs an approved inspection programme and the plate shows an ACEP reference instead of a fixed date. Either way, a container used for shipping must have current certification.
Do you need a CSC plate for your use?
This is the key question for most buyers. If the container will be shipped by sea — export cargo, a one-way move abroad — you need a valid, in-date CSC plate, which means buying a Cargo Worthy or One-Trip unit. If the container will stay on the ground as storage, a site office or a conversion, the plate's status does not affect its use — you are buying a steel box, not a shipping asset.
What to record when you buy
Whatever the use, note the container's serial number and the CSC plate details at purchase, and keep them with your tax invoice and release note. The serial identifies your exact unit for insurance, resale and any later shipping survey. Our inspection checklist includes checking the plate is present and legible. Buyers across Dammam, Riyadh and Jeddah can ask us to confirm CSC status before delivery.
