How to sell used car seats and boosters in Colombia without risks

Almost always, the car seat leaves the house for the same reason: the child grew up and the infant seat ended up in the junk room, that is, the corner of what is no longer used. On the other side is a dad who wants to save money, but looks at the ad with suspicion: is it expired? Has it been in an accident? If you are selling, your job is not to convince, it is to show. A photo of the label and two honest lines are worth more than any "like new, mate."

This guide is only for car seats, infant seats, convertibles, and boosters. If you are looking for a stroller or crib, check how to sell used cribs, playpens, and strollers; that case is there, and we will not repeat it here.

What should not be listed as suitable

There is no gray area here. A seat is equipment that only works if it holds up well on the day it matters. That is why I would skip selling it as "suitable" in these cases:

• A seat should not be advertised as suitable if its label shows a manufacturer's expiration or useful life date that has already passed, or if the date cannot be read. If only a manufacturing date appears, photograph it and do not invent an expiration period.
• The shell has cracks, the harness is frayed, or the buckles do not click shut.
• Parts are missing, as well as the base or the manual.
• It was in a moderate or severe crash. The NHTSA, the US road safety authority, recommends not using it again. This is a safety practice, not a Colombian traffic ticket.

Regarding a minor crash, the NHTSA itself considers it minor only if five conditions are met at the same time: the vehicle was able to drive away, the door closest to the seat was not damaged, no occupants were injured, the airbags did not deploy, and the seat has no visible damage. If you cannot confirm all five, do not present it as suitable. And if you do not know the history (for example, you bought it used), say so in the ad.

What the regulation says versus what is just a recommendation

It is best not to get confused here. What is law is Article 82 of the National Traffic Code, as it stands with Law 2393 of 2024, enacted on July 26, 2024: children under 10 years old cannot travel in the front seat, and children under 2 years old can only go in the back, in a seat that guarantees their safety and allows them to be secured to the seat, when traveling only with the driver.

What is not law is the 1.50 m figure. The National Road Safety Agency (ANSV) recommends using restraint systems at least until the child is 1.50 m tall and choosing the seat based on weight, height, and vehicle; age is only a reference. It is a safety recommendation, not the text of a traffic ticket. Also, do not present the safe seat bill known as the Guillermo Viecco Law as law. On June 11, 2026, Blu Radio reported that it was still awaiting the final debate in the House plenary. That report does not prove the status as of October 3, 2026, and does not make it law.

If you want to cite efficacy figures, attribute them with a date: a 2019 ANSV statement mentions 75% reductions in deaths and 90% in injuries with proper use, and in 2022 the Minister of Transportation said that use can reduce fatalities and serious injuries by up to 80%. Since the figures do not match, I would not put them in the ad as a promise.

How to read and photograph the label

Almost all seats have a label stuck to the shell or fabric, or molded into the plastic. It is the most important part of your ad. Photograph it up close, with good light and no glare, and make sure the following can be read:

• the weight or height range for which it works;
• the manufacturing date, if printed;
• if it exists, the expiration date or the "do not use after" warning;
• the standard acronym marked by the manufacturer (it could be ECE, i-Size, or another).

Watch out for a common mistake: that acronym informs the buyer, but it is not a procedure you have to do to post. No source in this guide requires ECE R44, R129, or FMVSS 213 for an individual to post an ad. FMVSS 213 is a US standard for new child restraint systems, and the federal obligation to comply with it does not cover resale after the first retail sale. Resolution 20223040044935 of 2022 regulates those systems in the chain of producers and vehicle suppliers, not a private classified ad. Resolution 20263040030325 of 2026 postpones the provisions in section 1.5 of that 2022 resolution to September 22, 2027. That postponement does not govern the ad. If the label cannot be read, do not claim homologation.

Complete it with a photo of the open harness and another of the buckles. Whoever buys looks right there.

What to put in the ad

A good ad answers before they ask, and that saves you from curious people who write "is it still available?" and then disappear.

1. Type: infant seat, convertible, or booster.
2. Printed range of weight or height, copied from the label.
3. How it is secured: with the car's seat belt or with lower connectors.
4. What it includes: base, manual, covers, infant inserts.
5. History: "no crashes that I know of" or "I don't know the history." Whatever you know, write it without embellishments.
6. Delivery: in person.

Regarding the price, I will not give you figures: it depends on the condition, the range it still covers, and whether it is complete. A seat with a legible label and complete parts defends itself; one without a label will have to be offered with more caution.

According to the active ads on Colombia Move (October 3, 2026), the Strollers, Car Seats, and Carriers category shows 4 active ads. There is low supply, so a clear ad stands out. If you are also going to sell clothes or cribs, check where to sell cribs, playpens, and baby clothes or the baby and kids section.

Warranty and occasional sale

Here, Law 1480 of 2011 (Consumer Statute) distinguishes according to who is selling. A supplier is someone who offers products on a regular basis. If you are one and sell a used item whose legal warranty has already expired, you must inform that it comes without a warranty and leave the buyer's acceptance in writing; otherwise, a three-month warranty is understood. In addition, the public offering of used items must state in a precise and noticeable way that they are used.

If you sell your child's car seat only once, an occasional sale does not make you a supplier just for posting. Even so, write "used, sold in the condition shown in the photos." It avoids complaints and is more honest with the buyer.

Delivery: where and how

• Meet to see the seat in person, in a public place with good lighting. The buyer should be able to check the harness and the label.
• Do not ship it against an advance payment. If someone insists on paying in advance and having it sent without seeing it, it is a classic sign of a scam.
• Do not disassemble the harness "to make it fit" in the car. If it doesn't fit, it doesn't fit.
• Tell the buyer to install it and test it in their own car before paying, if possible.

Frequently Asked Questions

❓ Can I sell the seat if the date printed by the manufacturer has already passed?

It should not be advertised as suitable if the expiration date or printed useful life has passed, or if the date cannot be read. If there is only a manufacturing date, photograph it and do not invent an expiration period. The ad must show that photo.

❓ Does the law require me to have an ECE R44, R129, or FMVSS 213 label to post it?

The sources consulted do not require that label for resale between private individuals. It should still be photographed because it provides information on the range, date, and standard the manufacturer marked. If it cannot be read, do not claim homologation.

❓ From what age is it mandatory to have a car seat in the vehicle?

Article 82 requires a seat for children under 2 years old who are in the back and traveling only with the driver, and prohibits children under 10 years old from sitting in the front seat. The 1.50 m figure is a recommendation from the ANSV, not the text of the traffic ticket.

❓ Does selling between private individuals oblige me to provide a three-month warranty?

The three-month warranty applies to regular suppliers who do not inform or leave written acceptance that the used item is sold without a warranty. An occasional sale does not in itself meet the definition of a supplier under Law 1480 of 2011, and the ad should still state that it is used.

❓ How much should I ask for a used seat or booster?

This article does not provide figures in pesos. The price depends on the condition, the range still covered by the label, and whether it is complete, and there is no source that sets it.

❓ How do I sell safely and avoid scams?

Delivery is in person, in a public place, and without advance payment. The buyer looks at the harness and the label, and the ad states the history that is known.

❓ Where do I post the seat without paying a commission?

In the baby strollers and car seats category on Colombia Move, with photos of the label and the harness. Posting there has no commission and the buyer contacts you directly. If you want to compare, you can also use other channels, but none of them save you from writing a clear ad.
