The European Union on Friday added Chinese-founded online retailer Shein to its list of digital companies that are large enough to come under stricter safety curbs.
The company joins Facebook, TikTok, X, and YouTube on 23 online platforms, with more than 45 million monthly active users in the European Union.
From the end of August, four months after the designation, Shein will have to apply the tougher rules under the Digital Services Act (DSA), one of the EU's landmark new laws against online platforms.
These include implementing measures to "protect consumers from purchasing unsafe or illegal goods, with particular focus on preventing the sale and distribution of products that could be harmful to minors", the European Commission said.
Shein has said it has around 108 million monthly active users in the 27-nation EU.
Reacting to the announcement, Shein said it would comply with the rules.
"We share the commission's ambition to ensure consumers in the EU can shop online with peace of mind, and we are committed to playing our part," said Leonard Lin, global head of public affairs at Shein.
Beyond the EU, Shein has faced fierce criticism with a litany of accusations from alleged exploitation of its factory workers with low pay to promoting hyperconsumerism to causing damage to the environment.
Brussels has flexed its legal muscle against the world's biggest digital platforms, launching investigations against TikTok, X and Chinese retailer AliExpress.
Another Chinese shopping app, Temu, is expected to be added to the EU's list after announcing in April that it has around 75 million monthly active users after entering the EU market a year ago.
Under the DSA, the platforms must assess the risks posed to Europeans' rights and safety by the content they publish, or the products on sale in the case of online marketplaces like Amazon and Shein, and submit a report to regulators.
At their own expense, they must also provide an external audit once a year to verify they comply with the rules.
The largest platforms are also subject to increased transparency, with the obligation to provide access to their data to researchers approved by Brussels.
