A U.S. federal agency has ruled that Amazon is responsible for recalling hundreds of thousands of defective products sold by third-party vendors.

On Tuesday, the Consumer Product Safety Commission (CPSC) issued a determination that Amazon, as a “distributor,” did not “provide sufficient notification to the public and did not take adequate steps to encourage its customers to return or destroy these hazardous items, thereby leaving consumers at risk of injury.”

More than 400,000 items, ranging from children’s clothing that violated federal flammability standards to hairdryers without electrocution protection to faulty carbon monoxide detectors were cited in the ruling.

Amazon said it's not responsible for sales made by third-party vendors

The decision comes three years after the CPSC filed its initial complaint against Amazon on July 14, 2021.

The e-commerce giant, which generated $575 billion in revenue through sales in 2023, did not contest that any of the products sold posed hazards to consumers, but argued that it did not have legal responsibilities for sales made by third-party vendors through its Fulfilled by Amazon program.

Amazon also claimed that its policy of sending messages to customers about “potential” safety hazards and providing them with credits towards future purchases rather than recalling defective items were remedies.

As part of the ruling, Amazon must now “develop and submit proposed plans to notify purchasers and the public about the product hazards, and to provide refunds or replacements for these products.”
