What year was my container built?

Where the build date actually lives

Every real shipping container carries a small metal plate near the door, usually on the right-hand door as you face the container from outside. It's called the CSC plate, short for the Convention for Safe Containers, and it's stamped, not painted, so grime and weather don't erase it the way they'd fade a decal.

That plate carries more than the date. Along with the month and year of manufacture, it lists the container's serial number, its maximum gross weight, its tare weight and the maximum weight it can carry stacked under others at sea. It's the closest thing a container has to a birth certificate, and it travels with the box its whole working life.

Why we can't just tell you over the phone

Ask us how old a box is and we'll ask you to go look at its plate, not because we're dodging the question but because we don't keep a master list of build years in our heads. A container that lands at our yard came from a shipping line or a leasing company that put it in service years ago, and its whole prior identity, owner prefix, serial number, build date, belongs to that history, not to a spreadsheet we maintain.

That's true of any used dealer, not just us. The plate is the one document that follows the steel from the factory floor to your driveway, so it's always going to beat a guess or a memory.

What the year does, and doesn't, tell you

Two boxes, same year, different lives

A build year alone is a weak predictor of condition. A container stamped ten years ago that spent most of that decade parked and lightly used can look better than one stamped three years ago that got hammered by forklifts and salt air on a busy trade route. Grade, cargo-worthy, wind and water tight, one-trip, describes the wear a box actually carries, and that's a separate question from the date on its plate.

If you're trying to judge a container you're about to buy, the grade and a walk-around tell you more than the year ever will. Our container grades guide breaks down what each label actually means.

Reading the plate without guessing

The plate sits low enough to read without a ladder, usually within arm's reach near the door hinges. Stamped characters can be dirty or lightly rusted after years outdoors, so a rag and a flashlight go a long way. The manufacture date is typically written as month and year, sometimes alongside the maximum operating gross weight in both pounds and kilograms.
