Manufacture & Expiry Dates
All infant capsules, car seats and booster seats expire. This includes all imported car seats. The lifespan range is 5-12 years, this is typically from the date of manufacture (DOM).
Diono has confirmed the life span now applies from the date of purchase of a new child restraint (this does not apply to second hand seats, bought or handed down), this is also stated in the child restraint manual. Where the seat is secondhand the lifespan applies from the date of manufacture.
Some seats state an expiration on the rear of the seat, or underside of the seat shell. The date is embossed on the seat and reads as "Do not use after" with a month and year. Otherwise the life span will be stated in the seat manual.
The life span does not depend on how well the seat was looked after, how long it has been stored between use or how many children have used the seat.
If you cannot find the expiry date,
you will then need to locate the manufacture date. Most will have a sticker with the date on the side of, or underneath the seat. All seats have a clock system stamped on them, some are easy to locate while others are hidden under the seat covers or other seat parts. The manufacture date helps identify how old the seat is, if it has been in any recalls and when it can no longer be used based on its life span .
If the sticker cannot be read, or cannot be found on the seat, is it likely that the seat has exceeded the maximum life span limit, or has been so many times that is is now in similar in condition to a seat that is 10 years old.
Once a seat expires, or has been in an accident, the life span becomes nil. The car seat needs to be disposed of safely, to prevent other people from using the seat again.
