The Commission fines Temu 200 million euro, the largest Digital Services Act penalty so far

The failure named is the risk assessment itself. It was built on general information about the e-commerce sector rather than evidence about Temu's own service, and it underestimated how often consumers in the EU would meet illegal goods. The size of the penalty is about how the assessment was done, not about any single listing.

Assess: A risk assessment written from sector research rather than your own data is the specific thing that was penalised.
