Shein Digital Services Act Duties: What a Very Large Online Platform Must Do

Shein has been a very large online platform under the EU’s Digital Services Act since April 2024. That label means it has to meet the strictest version of the DSA rulebook, and since 17 February 2026 it has also been the subject of formal Commission proceedings. Much of the coverage has focused on what Shein sells. This piece looks at the legal machinery: what the DSA requires Shein to do, how the Commission has used its powers so far, and how the Shein case compares with Temu, which was fined €200 million in May 2026.

Short answer: Shein was designated a very large online platform on 26 April 2024 after reporting more than 45 million monthly EU users. It must verify its traders, avoid dark patterns, assess and reduce systemic risks every year, pass independent audits, keep a public ad repository, explain its recommender systems and give researchers data. The Commission opened formal DSA proceedings against it on 17 February 2026.

Key takeaways

• The Commission designated Shein a very large online platform (VLOP) on 26 April 2024, giving it until the end of August 2024 to comply with the extra VLOP duties.
• Before opening proceedings, the Commission sent Shein three formal requests for information: on 28 June 2024, 6 February 2025 and 26 November 2025.
• The February 2026 investigation covers illegal products (including child-like sex dolls), addictive design such as points and rewards, and the transparency of Shein’s recommender systems.
• Temu went from formal proceedings in October 2024 to a €200 million fine in May 2026. A fine of up to 6% of global annual turnover is possible if breaches are proven against Shein.

When did Shein become a very large online platform?

The Digital Services Act, Regulation (EU) 2022/2065, applies to every online platform in the EU, but it saves its heaviest obligations for services with at least 45 million average monthly active users, roughly 10% of the EU population. Shein told the Commission it had an average of more than 45 million monthly users in the EU, and the Commission formally designated Shein a VLOP on 26 April 2024. Shein then had four months from notification, until the end of August 2024, to comply with the extra VLOP rules.

Designation changes who supervises the platform. For most services, the regulator is the Digital Services Coordinator in the country where the company is established. For a VLOP, the Commission becomes competent to supervise compliance, in cooperation with the national coordinator. Shein’s EU base is in Ireland, so Ireland’s media regulator, Coimisiún na Meán, is associated with the Commission’s investigation.

What does the DSA require of Shein as a marketplace?

Some duties have applied to every online marketplace since 17 February 2024. They matter because much of Shein’s business is a marketplace for third-party sellers.

Know your trader (Article 30). Before a trader can sell, the marketplace must collect its name, address, telephone number and email address, a copy of an identity document, payment account details, trade register details where it is registered, and a self-certification that it will only offer products that comply with EU law. The platform must make best efforts to check that the information is reliable and complete, and suspend traders who do not supply it.

Compliance by design and warnings to buyers (Articles 31 and 32). The interface must be designed so traders can give the information EU law requires, such as product safety details. If the platform learns that a trader has sold an illegal product, it must tell consumers who bought it in the previous six months, identify the trader and explain the redress available.

No dark patterns (Article 25). Platforms must not design their interfaces in a way that deceives, manipulates or otherwise distorts users’ ability to make free and informed choices. The Commission describes this as a ban on dark patterns.

Notice and action. Anyone, including a brand that finds counterfeits, must be able to report illegal content through an easy mechanism. Notices from trusted flaggers get priority, sellers whose listings are removed get a statement of reasons, and there must be an internal complaints system.

What extra duties apply because Shein is a VLOP?

The VLOP layer is about systemic risk and transparency. The Commission’s designation notice says Shein must analyse risks from illegal products and from the design of its own service, put mitigation measures in place against counterfeit goods, unsafe products and IP-infringing items, and pay particular attention to the physical and mental wellbeing of minors, including through age assurance for age-restricted items.

The advertising repository matters to fashion brands. Each entry must show the content of the ad, who paid for it, the period it ran, the main targeting parameters and how many people it reached. That is a useful source of evidence for anyone tracking how a product, or a lookalike of it, was promoted in the EU.

What has the Commission asked Shein so far?

The Commission’s enforcement usually starts with formal requests for information, which carry their own penalties: a provider that gives incorrect, incomplete or misleading answers can be fined up to 1% of its worldwide annual turnover. Shein received three. The first, on 28 June 2024, went to Shein and Temu together and asked about notice and action, illegal products and the protection of minors. The second, on 6 February 2025, focused on illegal products and the recommender system. The third, on 26 November 2025, followed reports that child-like sex dolls and weapons were on sale on the platform and asked for internal documents on preventing illegal sales, age assurance and how well Shein’s risk controls work.

A separate consumer law track runs in parallel. On 26 May 2025, the network of national consumer authorities known as the CPC Network, coordinated by the Commission, notified Shein of practices it considered unlawful: fake discounts, pressure selling with false deadlines, misleading information on returns and refunds, deceptive product labels, misleading sustainability claims and hidden contact details. That action is led by Belgium, France, Ireland and the Netherlands, and any fines would be imposed nationally. FLJ’s guide to whether Shein is legit covers the French fines and court rulings that sit alongside it, and the French anti-fast fashion law adds another national layer.

What is the Commission investigating in the formal proceedings?

On 17 February 2026 the Commission opened formal proceedings against Shein. The investigation has three strands:

• the systems Shein uses to limit the sale of illegal products in the EU, including content that could amount to child sexual abuse material, such as child-like sex dolls;
• the risks of addictive design, including points or rewards for engagement, and how Shein mitigates them;
• the transparency of its recommender systems, including whether users get at least one easily accessible option not based on profiling.

The Commission said the decision followed its analysis of Shein’s risk assessment reports, its replies to the three requests and information from third parties. Opening proceedings does not mean Shein has broken the law. It gives the Commission the power to adopt interim measures, accept binding commitments from Shein or issue a non-compliance decision. The DSA sets no deadline for finishing. As of the end of October 2026, the Commission had not announced preliminary findings against Shein.

How does the Shein case compare with Temu?

Temu is the closest precedent, and the two cases started almost in step. Both received their first requests for information on the same day. Temu, designated a VLOP on 31 May 2024, faced formal proceedings on 31 October 2024 covering illegal products, addictive design, recommender systems and researcher data access. Shein’s proceedings, opened more than 15 months later, cover the same ground except data access.

The Temu decision shows what the Commission will look for. According to the Commission’s announcement, Temu’s 2024 risk assessment relied on general information about e-commerce rather than evidence about its own service, seriously underestimated how often EU consumers were likely to meet illegal items, and ignored how recommender systems and influencer promotion programmes could spread them. The evidence included a mystery shopping exercise by an independent testing organisation and data from EU customs and market surveillance authorities. FLJ explains why clothing was part of that picture in The EU Just Fined Temu €200 Million.

The scale has grown since. On 20 July 2026 the Commission fined AliExpress €550 million for failing to assess and reduce the risk of illegal, unsafe and counterfeit products, and its announcement named counterfeit clothing among the harms. Shein’s own risk assessments will be measured against those two decisions.

What happens next, and what could Shein face?

The Commission’s enforcement framework sets out the tools. During the investigation it can send more requests, interview people and monitor the service. Where there is urgency and a risk of serious harm, it can order proportionate, temporary interim measures. If it finds a breach, it can fine a VLOP up to 6% of its global annual turnover and impose periodic penalty payments of up to 5% of average daily worldwide turnover for each day of delay. A non-compliance decision can also trigger a period of enhanced supervision.

The Temu decision shows the follow-up. Temu had until 28 August 2026 to file an action plan under Article 75, the European Board for Digital Services then had a month to give its opinion, and the Commission a further month to set an implementation period. The strongest step, a temporary suspension of the service, is a last resort. It needs a persistent breach causing serious harm and involving criminal offences that threaten life or safety, and it must be ordered by a court in the country of establishment.

What does this mean for brands and sellers on Shein?

For brands whose designs or trade marks appear on Shein’s marketplace, the DSA gives practical levers. Notices must be handled diligently, removal decisions must be explained, and an organisation that wins trusted flagger status gets priority. Article 30 means Shein should hold verified details about the trader behind a listing, which helps when a brand moves from takedown to legal action. Article 32 means buyers of an illegal product should hear about it.

For sellers, the message is that marketplace onboarding will keep getting stricter. Self-certification, identity checks and product safety information are legal requirements, and the Temu and AliExpress decisions show the Commission expects platforms to act on their own testing data. The DSA also works alongside customs changes, including the end of duty-free treatment for low-value parcels, covered in FLJ’s piece on the end of de minimis. The full DSA text is on EUR-Lex.

Frequently asked questions

Is Shein a very large online platform under the DSA?

Yes. The European Commission designated Shein a very large online platform on 26 April 2024 after Shein reported an average of more than 45 million monthly users in the EU. It had to comply with the extra obligations for very large platforms by the end of August 2024.

Has Shein been fined under the Digital Services Act?

Not as of the end of October 2026. The Commission opened formal proceedings on 17 February 2026, but it had not announced preliminary findings or a fine. The French fines Shein received in 2025 were imposed under national consumer and data protection law, not the DSA.

What is the Commission investigating Shein for?

Three things: whether Shein’s systems adequately limit the sale of illegal products, including child-like sex dolls; whether its design, such as points and rewards for engagement, creates addictive risks that it fails to mitigate; and whether its recommender systems are transparent and offer an option not based on profiling.

How much could Shein be fined?

Up to 6% of its global annual turnover if the Commission finds a breach. The Commission can also impose periodic penalties of up to 5% of average daily worldwide turnover to force compliance, and fines of up to 1% of turnover for incorrect or misleading answers to its requests.

What does Article 30 of the DSA require of Shein?

It requires Shein to collect and check identifying information from marketplace traders before they sell, including contact details, an identity document, payment account details, trade register details and a self-certification that their products comply with EU law. Traders who do not provide it must be suspended.

Why was Temu fined €200 million but not Shein?

Temu’s case started earlier. Formal proceedings opened in October 2024, preliminary findings followed in July 2025 and the fine came on 28 May 2026. Shein’s proceedings only opened in February 2026, and the DSA sets no deadline for an investigation to finish.

This article is general information, not legal advice. It reflects Commission announcements and the DSA text available at the time of writing; the formal proceedings against Shein do not prejudge any finding of breach.
