What to Do With an Expired Car Seat? | Safe Disposal Guide

The AAP advises against using an expired car seat.

Finding an old car seat in the back of the closet or realizing your child’s seat hit its expiration date six months ago is an oddly common moment. The seat itself looks fine — no cracks, no stains, no visible wear. It’s tempting to think it’s still usable, maybe for a younger sibling or as a backup for grandma’s car.

The reality is that car seats have a set lifespan, usually six years from the manufacture date. Materials degrade over time, and safety standards evolve. That seemingly fine seat might not protect your child the way a new one can. The goal is to get rid of it responsibly, and you have a few good options for doing exactly that.

What The Expiration Date Actually Means

Car seat expiration dates aren’t a ploy to sell more plastic. The materials — especially the polypropylene shell and the expanded polystyrene foam — wear down over time. Extreme heat and cold inside a parked car accelerate that process, making the plastic more brittle than it was on day one.

The American Academy of Pediatrics recommends against using any car seat past its expiration date. If you can’t find a sticker on the side or bottom of the seat, the rule of thumb is six years from the date of manufacture.

Handing down an expired seat to a friend or donating it might feel generous, but you’d be giving them a piece of safety equipment that’s past its prime. That’s why the most responsible move is to retire the seat completely.

Why It Feels Wrong To Throw It Away

It’s hard to toss something that looks perfectly functional. The straps are intact, the padding is clean, and it hasn’t been in a crash. That intuition makes sense — but the risks are hidden beneath the surface.

• Plastic degrades invisibly: After several years of UV exposure and temperature swings, the shell can become brittle. It might crack during a crash instead of absorbing the force.
• Safety standards shift: A seat that met the standards six years ago may not meet today’s side-impact or harness retention requirements. Newer models are tested against tougher criteria.
• Instructions get lost: Even if the seat is technically functional, missing manuals make correct installation less likely. Misuse rates for car seats are already high without adding an expired product into the mix.
• Hand-me-down pressure is real: Nobody wants to say no to free baby gear. But passing along an expired seat passes along a liability that the recipient might not recognize.

Once you accept that the seat has aged out of its safe window, you can focus on getting rid of it properly — and there are several satisfying ways to do that.

Where To Take An Expired Car Seat

The American Academy of Pediatrics recommends against using any seat past its expiration date, which is typically six years from manufacture. They stress that plastic degradation is invisible. You can read more about these safety guidelines in the AAP car seat expiration coverage. Once you’ve confirmed your seat is expired, several responsible disposal paths open up.

Retailer trade-in events are especially convenient. Target typically runs their Car Seat Trade-In program twice a year, offering a coupon toward a new seat. Walmart has partnered with TerraCycle to offer a similar program. These events make disposal easy while helping you budget for the next size up.

How To Prep A Car Seat Before You Get Rid Of It

Before you drop off or toss an expired seat, you need to make sure nobody else can pick it up and use it. An intact seat at the curb looks like a free find. Here’s how to make sure it’s truly retired.

1. Remove all fabric and padding: Most car seat covers snap or unclip easily. Take them off so they can be recycled or trashed separately from the plastic shell.
2. Cut the harness straps: This is the necessary step. Use sharp scissors or a utility knife to cut the straps completely. A seat without straps is obviously unusable.
3. Write “EXPIRED” on the shell: Grab a permanent marker and write in large letters that the seat is expired. That way, even if someone sees it, they won’t be tempted to grab it.
4. Separate the base (if applicable): Infant seats usually have a detachable base. Cut the straps on the base too before recycling or tossing it.

Taking these extra steps prevents someone from unknowingly using an unsafe seat. It also helps recycling centers process the materials faster when they arrive ready to handle.

Finding A Recycling Program Near You

Not all recycling centers accept car seats because they’re made from a mix of plastic, metal, and foam that’s hard to separate. But many areas are working to solve that problem. Some states have taken the lead on providing accessible recycling for families. For instance, you can find drop-off locations through the Colorado recycling program, which offers the service at no cost.

If you don’t live in Colorado, start by contacting your local waste management authority. Some private recyclers like Re-matt also accept car seats by mail or drop-off. It’s worth making a phone call.

Throwing a car seat in the landfill is sometimes unavoidable, but if a recycling option exists near you, it’s worth the extra trip.

The Bottom Line

An expired car seat isn’t a safety device you can keep using. The plastic degrades, the standards have moved forward, and the risk just isn’t visible from the outside. Your safest plan is to cut the straps, mark the shell, and hand it off to a retailer trade-in program or a local recycling center.

If you’re not sure whether your seat is expired or you just need help finding a drop-off location nearby, a certified Child Passenger Safety Technician can point you in the right direction — your local hospital or fire department usually has a list of upcoming seat-check and recycling events.
