Article 16: the twelve duties of a provider of a high-risk AI system
Article 16 is the summary list of duties for providers: twelve points that route onward to the quality management system, the documentation, the logs, the conformity assessment, the EU declaration of conformity, the CE marking, the registration, corrective actions and accessibility requirements.
Applies to providers of high-risk AI systems. For the standalone Annex III route (Article 6(2)) the date is 2 December 2027. For systems embedded as a safety component in products covered by the Annex I harmonisation legislation (Article 6(1)) the date is 2 August 2028.
A provider that considers an Annex III system not to be high-risk must document that assessment before placing it on the market and remains subject to the registration obligation of Article 49(2) (Article 6(4)). Where an AI system referred to in Annex III performs profiling of natural persons it is always considered high-risk (Article 6(3), final subparagraph).
Article 16 requires providers of high-risk AI systems to do twelve things. They must ensure their systems comply with the requirements of Chapter III, Section 2 (point (a)); indicate on the system or, where that is not possible, on its packaging or accompanying documentation, their name, registered trade name or registered trade mark and the address at which they can be contacted (point (b)); have a quality management system in place complying with Article 17 (point (c)); keep the documentation referred to in Article 18 (point (d)); keep the automatically generated logs referred to in Article 19 when under their control (point (e)); ensure the system undergoes the conformity assessment procedure referred to in Article 43 prior to being placed on the market or put into service (point (f)); draw up an EU declaration of conformity in accordance with Article 47 (point (g)); affix the CE marking in accordance with Article 48 (point (h)); comply with the registration obligations referred to in Article 49(1) (point (i)); take the necessary corrective actions and provide the information required under Article 20 (point (j)); upon a reasoned request of a national competent authority, demonstrate conformity with the requirements of Section 2 (point (k)); and ensure the system complies with the accessibility requirements of Directives (EU) 2016/2102 and (EU) 2019/882 (point (l)).
Article 16 reads like a table of contents and is therefore often planned as a single roadmap line. It is twelve separate duties with widely differing lead times: building a quality management system takes months, affixing a CE marking takes a day. The bigger trap sits in Article 25(1): anyone who puts their own brand on an existing high-risk system, substantially modifies it, or changes the intended purpose of a non-high-risk system so that it becomes high-risk counts as a provider and inherits all twelve points without ever having built anything. In the branding scenario of point (a) this applies without prejudice to contractual arrangements stipulating that the obligations are otherwise allocated, but you must have made and be able to show those arrangements in advance. In practice this catches parties that white-label AI or apply a general-purpose model to an Annex III use case.
First determine whether you are a provider or whether Article 25 makes you one, then work out the twelve points as twelve separate work packages with an owner and a date. Start with points (c) and (f), because they set the lead time of the whole track.
