- “Minor Crash” Has a Strict Definition: According to the NHTSA, a seat may be reusable after a minor crash only if it meets five specific criteria, including that the vehicle was drivable and no one was injured.
- Vetted Retailers Exist: Some companies, like GoodBuy Gear, specialize in selling used car seats but only after they have undergone a thorough safety inspection process, offering a layer of protection for buyers.
The Verdict for 2025: Can You Legally and Safely Sell a Used Car Seat?

While no federal law explicitly forbids the private sale of used car seats, the practice is governed by a web of safety standards and legal responsibilities that fall squarely on the seller. The primary function of a car seat is to save a child’s life in a collision, and any compromise to its structural integrity—the core strength of its frame and materials—can have catastrophic consequences.
According to guidance from both the CPSC and the NHTSA, selling any children’s product that is damaged, has been recalled, or does not meet current safety standards is a serious matter. A recall, for instance, is issued when a product has a known safety defect. Selling a recalled and unrepaired car seat isn’t just unethical; it’s against the law. Therefore, when you decide to can you sell used car seats, you are taking on the responsibility of guaranteeing that seat is as safe as the day it was made.
Selling or buying a used car seat carries inherent risks because the seat’s full history might not be known. Any compromise to its structural integrity can be life-threatening. Prioritizing safety is paramount when you consider if can you sell used car seats.
So, while the answer is yes, the more important question is: should you sell it, and how can you do so without risking a child’s safety?

The Unbreakable Rules: A 2025 Safety Checklist for Sellers & Buyers
To safely and ethically can you sell used car seats, you must follow a strict set of non-negotiable rules. This checklist serves as the definitive guide for both sellers and potential buyers, ensuring that no critical safety aspect is overlooked. Think of this not just as a recommendation, but as the minimum standard of care required when a child’s safety is on the line.
Pro Tip: “Before you even think about listing your car seat, grab the owner’s manual. This will be your single source of truth for checking parts and specifications.”
A complete used car seat safety inspection involves confirming its crash-free history, checking the expiration date and for recalls, ensuring all parts are present and undamaged, and knowing the seat’s full ownership history. Failure to verify even one of these points should immediately disqualify the seat from being sold or passed on.
- Verify the Seat’s Complete and Undeniable History
- This is the absolute first step. If you cannot confirm the seat’s entire past, you cannot guarantee its safety.
- Confirm Zero Involvement in a Crash
- This is a critical safety factor. The forces in a collision can cause hidden damage. We will detail the only exception: a verified “minor crash.”
- Locate and Respect the Expiration Date
- All car seats expire. Selling an expired car seat is irresponsible and dangerous.
- Perform a Thorough Recall Check
- You must ensure the specific make and model has no outstanding safety recalls.
- Conduct a Full Physical Inspection
- Every strap, buckle, and piece of plastic must be present and in perfect working order, free from wear and tear that could compromise safety.
Rule #1: You Must Know the Seat’s Complete History (No Exceptions)
Only sell a car seat if you are the original owner and can guarantee it has never been in a moderate or severe crash. For minor crashes, you must consult the manual and meet all five specific safety criteria. This is the foundational rule of selling a used car seat. If you bought the seat at a garage sale or were given it by a neighbor, you cannot know with 100% certainty what it has been through. A seller must be able to provide an undeniable, comprehensive understanding of the seat’s entire history to guarantee its safety.
The most critical element of this history is its involvement in any vehicle collision. Most manufacturers, along with the NHTSA, recommend replacing any car seat that has been in a moderate or severe crash, even if the seat appears undamaged.
Quick Fact: Forces in a collision can cause micro-fractures in a car seat’s plastic shell that are completely invisible to the naked eye.
There is a very limited exception for what is defined as a “minor crash.” Some manufacturers may allow for reuse if, and only if, all of the following criteria are met:
* The vehicle was physically able to be driven away from the crash site.
* The vehicle door nearest to the car seat was completely undamaged.
* There were absolutely no injuries to any of the occupants in the vehicle.
* The vehicle’s airbags did not deploy during the incident.
* There is no visible damage whatsoever to the car seat itself.
If a car seat was in a crash that does not meet every single one of these points, it is not safe to use or sell. The seller must consult the owner’s manual for the specific manufacturer’s recommendations.
When in doubt, throw it out.
Rule #2: Locate and Verify the Expiration Date
Check the manufacturer’s sticker or the plastic shell for the expiration date, which is typically 6-9 years after the date of manufacture. Never sell or use an expired seat. Many people are surprised to learn that car seats have a shelf life, but it’s a critical safety feature. The reason, as explained by safety organizations like healthychildren.org, is material degradation. Over time, exposure to extreme temperatures in a car and simple aging can make the plastic components brittle and less able to withstand crash forces. The harness webbing can also weaken.
To determine if you can you sell used car seats, you first need to find the dates. Look for:
* The Date of Manufacture: This is usually on a mailing-label-sized sticker on the side or back of the seat. This is the starting point for the seat’s lifespan.
* The Expiration Date: This might be on the same sticker or imprinted directly into the plastic shell of the seat. It will often say “Do Not Use After [Date].”
It’s important to start with the date of manufacture, as the expiration is calculated from this point. A seat made in June [year-8] with a 6-year lifespan would have expired in June [year-2].
According to The Car Seat Lady, a leading authority on car seat safety, a sold used seat should have significant life remaining. They recommend “at least one year for rear-facing only seats, 2-3 years for convertible seats, and enough time for a booster seat to last until a child is around 10 years old.”
Rule #3: Perform a Thorough Recall Check
Using the model number and date of manufacture, check for recalls by contacting the manufacturer or using the NHTSA’s online database. Any recall issues must be resolved before selling. It is illegal to sell a recalled product that has not been repaired. A recall means the manufacturer has identified a safety defect that could put a child at risk. Fortunately, checking for recalls is a straightforward process.
To find out if you can you sell used car seats without legal and safety issues, follow these steps:
- Gather Your Information: Find the manufacturer’s information sticker on the car seat. Write down the Manufacturer Name, Model Name, Model Number, and the Date of Manufacture.
- Check the NHTSA Database: The National Highway Traffic Safety Administration maintains a comprehensive, easy-to-use database of all car seat recalls. You can enter your seat’s information to see if any recalls have been issued.
- Contact the Manufacturer: If you’re unsure or want to double-check, you can call the manufacturer’s customer service line directly with your seat’s information. They can confirm its recall status and tell you how to get a repair kit if one was issued.
Most recalls can be fixed with a simple repair kit that the manufacturer provides for free. If a recall has been issued for the seat, you must order and properly install the fix before you can consider selling it.
Where to Sell Used Car Seats: From Vetted Retailers to Online Marketplaces

Smart Alternatives: What to Do With Old Car Seats If You Can’t Sell
If a car seat is expired, damaged, or has an unknown history, do not sell it. Instead, take advantage of retail trade-in events like Target’s for a discount, or discard it to ensure it cannot be used unsafely. After going through the safety checklist, you may find that you can you sell used car seats is not the right decision for your particular seat. If it’s expired, been in a crash, is missing parts, or you simply don’t know its full history, choosing not to sell is the most responsible choice you can make.
But that doesn’t mean it has to end up in a landfill. Here are the best alternatives:
- Retail Trade-In Events: This is by far the best option for old, expired, or damaged car seats. The most well-known of these is the Target Car Seat Trade-in Event.
- Target holds this event seasonally, where they will accept and recycle all types of car seats.
- Accepted items include: infant car seats, convertible car seats, car seat bases, harness or booster seats.
- They accept seats that are expired or damaged.
- In exchange for the old seat, guests receive a 20% off coupon for a new car seat, stroller, or select baby gear.
- Local Recycling Programs: Some municipal recycling centers have programs that can properly break down and recycle car seats. This is less common, so you will need to check with your local waste management authority. They may require you to strip the fabric and foam from the plastic shell first.
- Proper Disposal: If recycling or trade-in isn’t an option, you should make the seat unusable before discarding it. Cut the harness straps, write “EXPIRED – DO NOT USE” in permanent marker on the shell, and remove the padding. This helps prevent someone from pulling it from the trash and using an unsafe seat.
Pro Tip: Mark your calendar for Target’s trade-in events, which typically happen seasonally. It’s a fantastic way to recycle responsibly and save money.
To ensure the car seat you’re selling is in the best possible condition, or to clean one you’ve responsibly acquired, having the right tools is essential.
