What compliance steps are required for marketplaces under the DSA?

 Online marketplaces must go beyond standard notice and action.

The DSA requires traceability of traders and reasonable steps to check sellers and product compliance. Platforms must perform random checks against relevant databases and act swiftly on illegal product notices. They should also enable users to report dangerous or counterfeit goods easily and provide clear statements of reasons when listings are removed.

Practical steps include KYC for traders, product compliance attestations, proactive duplicate detection, and transparency reporting that breaks out product enforcement metrics.
