There should be a month/year stamped into the metal at the top near the neck. If there is no stamp, it probably needs hydro. Some gas places will just exchange it for you unless your area is a fill while you wait. If so, try a fire safety place that supplies and maintains extinguishers.

It's the date the tank was hydro-tested. They have to be tested every 5yrs.

My local gas shop charged me an extra $15 to hydrotest the one that I traded in so that is awesome for $10. Just look for the stamp next time if you pick up another CO2 cylinder

yes, out of date cylinders have to be re-tested. But this is often much cheaper than a new cylinder! If you don't know the date of your cylinder, just take it to the refill place & they can tell you. Also, they are supposed to check before they refill, so if it's out of date, they won't refill. But you can leave it, they will test it, remark it, and refill it for you.
