EU AI Act Article 50: the four transparency obligations every EU storefront will face in 2026
The EU AI Act (Regulation 2024/1689) entered force on 1 August 2024. The transparency obligations in Article 50, which catch every EU storefront using a chatbot or AI-generated product imagery, become enforceable from 2 August 2026. Here is what each of the four obligations actually requires, who has to comply, and what "appropriately marked" means in practice.
Article 50 of the EU AI Act is the part of the Regulation that most EU storefronts will actually encounter. It does not require a risk classification, a notified body, or a conformity assessment. It requires a label.
The Regulation entered force on 1 August 2024. Article 50 starts applying on 2 August 2026. The 24-month gap was the legislative compromise that allowed the rest of the Act to enter force quickly while giving providers and deployers time to wire up labelling.
Obligation 1: AI chatbots must disclose
Providers shall ensure that AI systems intended to interact directly with natural persons are designed and developed in such a way that the natural persons concerned are informed that they are interacting with an AI system, unless this is obvious from the point of view of a natural person who is reasonably well informed.
Every Intercom, Drift, Tidio, Crisp, Zendesk, and LiveChat AI chatbot deployed on an EU storefront falls within the obligation if the bot is AI-driven and the user is in the EU. The exception for "obvious" AI cases is narrow. A first-message disclosure such as "You are chatting with our AI assistant. Type 'human' to speak to a person." satisfies the requirement.
Obligation 2: Emotion recognition systems
Article 50(2) requires deployers of an emotion recognition or biometric categorisation system to inform the natural persons exposed to it. The obligation is rarely relevant for an e-commerce storefront, but it does apply to in-store smart cameras connected to an online storefront, and to behavioural emotion-analysis layers that some checkout-conversion tools claim to provide.
Obligation 3: Deepfake and synthetic media must be marked
Article 50(4) is the obligation that most affects storefronts using AI-generated product photography or AI-generated lifestyle imagery. "Image, audio or video content constituting a deep fake" must be marked as artificially generated or manipulated.
EnforcementEuropean Commission, Q&A on Article 50 published 9 February 2026: a still product image of an item that does not exist in the trader's catalogue, generated by a text-to-image model, is treated as synthetic media within the meaning of Article 50(4). An edited photograph of a real product (background swap, colour correction) is not, provided the underlying product depiction remains accurate.
Obligation 4: AI-generated text must be marked when published for the public interest
Article 50(4) second subparagraph extends the marking obligation to AI-generated text "published with the purpose of informing the public on matters of public interest". A storefront's marketing copy is not on its face within scope. A storefront's news section, blog, or sustainability claims may be, depending on the subject matter. Conservative practice is to mark AI-generated blog and editorial copy regardless.
What does "appropriately marked" mean?
The Regulation does not prescribe a label. It requires the mark to be in a "machine-readable format and detectable as artificially generated or manipulated". Industry practice in mid-2026 is converging on two layers: a human-visible badge near the content (the words "AI-generated" or a recognised pictogram) plus C2PA content credentials embedded in the file metadata. C2PA is supported by Adobe, Microsoft, Sony, Leica, and the major AI image providers.
How we test thisComplianceGuardHQ flags AI chatbots without disclosure as a medium-severity Article 50(1) issue. AI-generated product imagery without a visible label is flagged as a warning rather than a violation, because the vision-classifier confidence is rarely high enough to reach our deterministic-detection threshold. The warning carries a confidence score so a human reviewer can prioritise.
What to audit this week
Inventory your chatbot vendors. Confirm each AI assistant exposed to EU users displays the AI nature of the system on its first message. Inventory the product photography pipeline. For every AI-generated still, add a visible "AI-generated" caption and embed C2PA content credentials. If you publish AI-generated editorial content (blog posts, sustainability statements), add the same label and credentials.
Run a free scan of your live storefront. ComplianceGuardHQ surfaces every detected chatbot vendor without disclosure and every detected likely-AI image without a visible label, with the page URL and the suggested label text. The scan takes about 60 seconds and requires no install.
Frequently asked questions
When does the EU AI Act Article 50 take effect?
Regulation (EU) 2024/1689 entered force on 1 August 2024. Article 50 transparency obligations start applying on 2 August 2026, two years after entry into force. Other provisions of the Regulation have earlier or later start dates: prohibited practices applied from 2 February 2025, general-purpose AI rules from 2 August 2025, and the bulk of the Regulation from 2 August 2026.
Do I need to disclose that my support chatbot uses AI?
Yes, if the chatbot is genuinely AI-driven and your users are in the EU. Article 50(1) requires natural persons interacting with the AI system to be informed of its AI nature, unless that is obvious to a reasonably well informed person. A first-message disclosure on every chat session satisfies the requirement.
Do I need to label AI-generated product photographs?
Generally yes. The European Commission Q&A of 9 February 2026 treats a still image of an item that does not exist in the trader's catalogue, generated by a text-to-image model, as synthetic media within the meaning of Article 50(4). The mark must be machine-readable and detectable. Industry practice combines a visible "AI-generated" caption with C2PA content credentials embedded in file metadata.
Does Article 50 apply to background swaps and colour corrections?
No. The Commission Q&A confirms that an edited photograph of a real product (background swap, colour correction, retouching) is not synthetic media for Article 50(4) purposes, provided the underlying product depiction remains accurate.
What format does the AI-generated label need to take?
The Regulation does not prescribe a format. It requires the mark to be "in a machine-readable format and detectable as artificially generated or manipulated". The European Commission's 2025 implementation guidance recommends a combination of a human-visible label (the words "AI-generated" or an equivalent pictogram) and C2PA content credentials, which are supported by Adobe, Microsoft, Sony, Leica, and the major AI image providers.
