US regulators have ruled that Amazon is responsible for handling recalls of unsafe products sold on its site and must improve its process.

They said Amazon’s alerts were not sufficient to convince its customers to stop using such products and ordered the company to submit a new plan for how it will respond.

The decision by the US Consumer Product Safety Commission (CPSC) came after the agency sued the e-commerce giant in 2021 for distributing more than 400,000 hazardous items, including faulty carbon monoxide detectors.

Amazon said it planned to appeal the finding, while defending its practices.
