Under Article 6(4) of the EU AI Act (Regulation (EU) 2024/1689), a provider who concludes under Article 6(3) that its Annex III system is not, in fact, high-risk still has to register that system in the EU database — with a short summary of the grounds on which it reached that conclusion. That entry sits in the public section. The Commission’s Digital Omnibus proposal of 19 November 2025 tried to delete this obligation outright. Both the Council, in its negotiating mandate of 13 March 2026, and the European Parliament’s IMCO and LIBE committees, in a joint report adopted five days later on a 101-9-8 vote, independently rejected the deletion. The final text reinstates registration, with streamlined content requirements. If your compliance plan was drafted off the November proposal, it’s currently wrong.
The rule in one paragraph
Exemption doesn’t mean invisibility. Concluding that your Annex III system clears the Article 6(3) bar doesn’t end your paperwork — it starts a different kind. You keep the internal assessment that got you to that conclusion, you file a summary of it in the EU database, and that summary sits where the public can read it.
The three database categories
The EU database sorts entries into three categories, and who files depends on which one applies:
- Category 1 — genuinely high-risk systems under Article 6(2) and Annex III. Filed under Annex VIII Section A. The provider files.
- Category 2 — systems a provider has assessed as not-high-risk under Article 6(3). Filed under Annex VIII Section B. The provider files.
- Category 3 — high-risk systems used by public authority deployers. Filed under Annex VIII Section C, including a summary of the data protection impact assessment carried out under Article 35 GDPR. The deployer files, not the provider.
Category 2 is the one that catches people off guard, precisely because “not high-risk” sounds like an off-ramp from the database entirely. It isn’t.
What your competitors get to read
Category 2 entries go into the public section of the database, the same section genuinely high-risk registrations sit in. The public section is free to access, navigable, and machine-readable. That’s not a side effect — it’s the design.
The practical consequence is straightforward and easy to underestimate: the legal argument you’re relying on to stay out of the high-risk regime is a document a competitor, a journalist, or an NGO can read, and can challenge. If your reasoning under Article 6(3) is thin, it’s thin in public.
The Article 80 backstop
Article 80 gives market surveillance authorities a specific procedure for exactly this situation, and it’s worth reading in full rather than taking on faith. Where an authority has sufficient reason to believe a system a provider classified as not-high-risk is actually high-risk, it tests that classification against the Article 6(3) conditions and the Commission’s guidelines. If the test confirms the system is high-risk, the authority orders the provider to bring it into compliance within a deadline the authority sets. Miss that deadline, and fines follow under Article 99 — that’s the backstop the brief refers to, and it’s a real, specific consequence, not a vague risk of reputational harm.
There’s a second, sharper consequence sitting one paragraph later. If the authority’s review finds the provider classified the system as not-high-risk specifically to circumvent the Chapter III Section 2 requirements — not a good-faith misjudgment, but an evasive one — that draws its own, separately finable violation under Article 99.
And Article 80 names its own evidence source. In exercising their oversight, market surveillance authorities may carry out checks that take into account, in particular, information stored in the EU database. That’s not a general observation about transparency — it’s the Act telling authorities where to look first. Your Category 2 summary isn’t a filing that disappears into an archive; it’s a named input into exactly the kind of review Article 80 describes.
What the Omnibus changed
The sequence is worth having straight, because it moved more than once. The Commission’s Digital Omnibus package, published 19 November 2025, proposed deleting the Article 6(4) registration obligation for self-assessed not-high-risk systems entirely. The Council’s negotiating mandate of 13 March 2026 rejected that specific deletion while broadly aligning with the Commission elsewhere, reinstating a simplified registration obligation. Five days later, on 18 March 2026, the Parliament’s IMCO and LIBE committees adopted a joint report doing the same, by a 101-9-8 vote. A provisional political agreement reached on 7 May 2026 confirmed the reinstatement, with streamlined Annex VIII Section B content — fewer data points required in the filing, without removing the filing itself. Parliament adopted the final text on 16 June 2026, and the Council gave its final green light on 29 June 2026.
What’s actually different in the streamlined Section B, line by line, isn’t something I can confirm precisely — commentary consistently describes it as a reduced set of required data points rather than a restructured form, but I haven’t seen the specific before-and-after list. What isn’t in question is the outcome: the obligation survived a deletion attempt from its own drafter, unanimously rejected by both co-legislators before trilogue even started.
One more date worth anchoring this to: Annex III high-risk obligations, under the same reform, now apply from 2 December 2027 rather than the original 2 August 2026. The registration duty for Category 2 systems tracks that same timeline.
The one Annex III category that escapes the EU database
There’s a genuine exception, and it’s narrow. High-risk AI systems falling under Annex III point 2 — critical infrastructure — register at national level instead of in the EU database. The Act doesn’t name a single EU-wide national register to check; the obligation is simply pushed down to whichever Member State mechanism applies, and that mechanism isn’t uniform across the Union. If your system is critical-infrastructure-adjacent, “check the EU database” isn’t the right instruction to give your compliance team.
Frequently asked questions
Do I register before or after placing the system on the market?
Before. Registration is structured as a precondition tied to placing the system on the market or putting it into service, not a filing you make afterward to tidy up the paperwork. Treat the Article 6(3) assessment and the database entry as part of your go-live checklist, not a follow-up task.
What if my system triggers the profiling override?
Then Article 6(3) isn’t available to you at all. Any Annex III system also used to profile natural persons is high-risk regardless of how narrow, preparatory, or human-reviewed its role looks otherwise — there’s no exemption to claim. You’re in Category 1, filing under Annex VIII Section A, not Category 2.
Can I redact the grounds I file?
Not for a standard Category 2 entry — the summary of your grounds is what goes in the public section, and that’s the point of the filing. Restricted, non-public treatment is reserved for specific categories named in the Act, chiefly biometrics, law enforcement, migration and border control, and similar sensitive uses. A conventional HR, credit, or education system claiming the Article 6(3) exemption doesn’t get that treatment.
Who registers if we’re the importer, not the original developer?
Ordinarily, the original provider — including one established outside the EU, acting through its EU authorised representative. You become the provider yourself, with the provider’s registration duty, only if you put your own name or trademark on the system, make a substantial modification to it, or modify a non-high-risk system’s intended purpose in a way that makes it high-risk. A straightforward import without any of that doesn’t shift the filing obligation onto you.
Does this apply to a system already on the market?
This is genuinely less settled than the rest of this piece. The Act’s general grandfathering rule protects high-risk systems already on the market from the new obligations unless they undergo significant changes, and the same logic would plausibly extend to a system you’d assessed, before the relevant date, as not needing Article 6(3) registration at all. But I haven’t found a source that addresses this specific edge case directly, so treat it as a reasonable inference rather than a confirmed answer, and check it against the Commission’s guidance before relying on it.
