You bought a used container, or you are about to, and someone told you it needs to be “certified” before it can ship overseas. They are half right. Here is the whole path, step by step, including the exit ramp most people should take at step 2.
One definition before we start. “Certified” here means the container has a CSC Safety Approval plate and a current examination status under the international container safety convention (CSC 1972), which the US enforces through Coast Guard regulations at 49 CFR Parts 450 through 453. If you want the full background, our container certification guide covers the whole system. This post is just the how.
Step 1: Check what you actually have
Open the left-hand door and look for the metal CSC plate riveted near the bottom. Three things to check:
- Is the plate there at all? It usually is; it stays with the box for life.
- Is there an NED decal with a future date? NED means Next Examination Date. A future date means the examination status is current. Rare on a used box, but check.
- Is there an ACEP marking instead? A marking like ACEP/USA followed by a year means the box was covered by a fleet owner’s continuous examination program. Here is the catch: the program belonged to the fleet, not the box. When the line sold the container, it removed the box from the program, and the coverage ended. Per the Container Owners Association’s guidance (COA TG03), the buyer inherits responsibility for CSC maintenance from that point on.
So the usual answer for a used box is: plate present, examination status lapsed. That is normal. It is not damage and not a defect. It just means the box is retired from ocean work until someone re-examines it. Our container reference shows where every marking lives if you want help reading yours.
Step 2: The escape hatch. Are you actually shipping internationally?
Stop here and answer honestly, because this step ends the project for most readers.
CSC certification applies to international transport only. If your container will store equipment, sit on a job site, or move by truck anywhere inside the United States, you need nothing. No survey, no decal, no paperwork. A lapsed examination status has zero effect on domestic use. People pay for surveys they never needed because a listing said “expired” and it sounded urgent. It is not. If you are not putting this box on a ship, you are done. Enjoy the container.
Still here? Then you have a real booking ahead. Continue.
Step 3: Find a qualified examiner
The regulation is looser than you would expect. 49 CFR 452.3 requires examinations by “qualified personnel, trained and experienced,” and no US government license for container surveyors exists. In practice, the credential that matters is IICL inspector certification, earned by exam and renewed every five years, because ocean carriers know it and accept reports behind it. The IICL’s “Find a Certified Inspector” directory is the one real listing of these inspectors.
Practical routes, in order:
- Ask a container depot. Depots coordinate most surveys, since the box, the forklift, and the inspector meet there anyway.
- Search the IICL directory for an inspector in your region and contact them directly. Our container inspector finder lists that directory’s full US roster, grouped by state.
- Ask your freight forwarder or carrier who they accept. The carrier is the final judge of any report, so their answer outranks everything.
Questions worth asking before you book: Are you IICL certified? Will I get a written report and an NED decal on a pass? Have your reports been accepted by the carrier I am booking with?
Step 4: Survey day
The examiner inspects the container against industry criteria, structure first. Expect attention on the corner castings and posts, the top and bottom rails, the cross members and underside, the floor, the doors and gaskets, the side and end panels, the roof bows, and weathertightness overall. The underside matters, which is why surveys usually happen where a forklift can raise the box. A container sitting on grass at your place is a harder, costlier survey than the same box at a depot.
On timing, providers publish turnarounds of about two to five business days for the survey and report. Treat that as their published figure, not a promise; your depot and inspector set the real schedule.
Step 5: What you get, and what it does not guarantee
A passing survey gets you two things: a new NED decal on the plate and a written examination report. Together with the plate, that is your “certified” container.
One honest caveat: the carrier still decides. A survey report is evidence, not a ticket. Hapag-Lloyd, for example, publishes requirements for shipper-owned containers that include a valid CSC plate and certificate, minimum stacking and racking values, ISO 668 dimensions, and a proper ISO 6346 number. Book early, send your paper to the carrier, and confirm acceptance before the box heads to port.
If it fails: know when to fold
Surveys fail on real structural findings: cracked castings, bent rails, corroded cross members, floor damage. Repairs to survey standard are steel work by qualified hands, and on an older box they can cost more than the box justifies. There is no shame in the math.
The alternative is usually smarter: buy a cargo worthy (CW) container from a depot, tell the seller it is for export, and have it surveyed at booking, since carriers want a fresh certificate for shipper-owned boxes anyway. One warning from our condition guide applies here too: a dealer grade is not a certification. Even a box sold as cargo worthy needs its own valid examination before a carrier takes it.
What it costs
Published figures, attributed: IPL publishes container survey pricing of $75 to $250 per container. A greater-Cincinnati inspector publishes a rate of $125 per hour including travel, plus a depot handling fee. Location, access, and the box’s condition move the final number, and any repairs are on top.
The bottom line
Check the plate. If you are not shipping internationally, stop at step 2 and spend the money on a lock instead. If you are, use an IICL-certified inspector through a depot, get the NED decal and report, and clear it with your carrier before the box moves. And if the booking is still hypothetical, do not certify a storage box on spec. Buy for the job you actually have.
