High-risk AI under the EU AI Act

The EU AI Act classifies AI systems as "high-risk" via two independent routes: the Annex I product route (AI as a safety component of CE-marked products) and the Annex III use-case route (8 listed application areas). Use this reference to check whether your AI system falls into either category - and whether the Article 6(3) filter brings it back out. Article 6

The short version

  • Route 1 - Annex I (product safety): AI that is a safety component of a product regulated under EU harmonisation law (machinery, medical devices, toys, vehicles, aviation, etc.) and required to undergo third-party conformity assessment.
  • Route 2 - Annex III (8 use-case areas): Stand-alone AI systems in biometrics, critical infrastructure, education, employment, essential services, law enforcement, migration/asylum, or administration of justice and democratic processes.
  • Article 6(3) filter: An Annex III system is not high-risk if it does not pose a significant risk of harm to health, safety or fundamental rights - but this exception does not apply where the system profiles people.

Two routes to high-risk

How an AI system becomes high-risk

Route 1 - Annex I

Safety component of a regulated product

AI that is a safety component of, or is itself, a product regulated under the EU harmonisation laws listed in Annex I (e.g. machinery, medical devices, toys, motor vehicles, aviation equipment) and that product is required to undergo third-party conformity assessment. Annex I

Obligations under Route 1 apply from 2 August 2027 under current law ([OMNIBUS - PROPOSED] deferred to 2 August 2028 if the Digital Omnibus is adopted - not yet law as of 9 June 2026).

Route 2 - Annex III

Listed high-risk use-case area

Stand-alone AI systems that fall in one of the 8 use-case areas in Annex III - unless the Article 6(3) filter applies. The filter requires a documented assessment that the system does not pose significant risk of harm. It cannot be used if the system profiles natural persons. Annex III

Obligations under Route 2 apply from 2 August 2026 under current law ([OMNIBUS - PROPOSED] deferred to 2 December 2027 if the Digital Omnibus is adopted - not yet law as of 9 June 2026).

Article 6(3) filter - not a free pass

The Article 6(3) filter allows an Annex III system to avoid the high-risk classification if it does not pose a significant risk of harm. Indicators of non-significant risk: the system performs a narrow procedural task; it improves a prior human activity; it detects decision-making patterns without replacing human judgement; it performs preparatory tasks only. The filter does not apply where the system profiles natural persons. You must document your filter assessment and be prepared to defend it. Article 6(3)

14 areas shown

High-risk AI use cases under the EU AI Act. Columns: area, category, example use cases, and a compliance note.
AreaCategoryExample use casesNote
Biometrics (area 1)Annex III
  • Remote biometric identification systems (face, gait, fingerprint)
  • Biometric categorisation systems inferring attributes from biometric data
  • Emotion recognition systems used outside prohibited contexts
Excludes uses already banned by Article 5 (untargeted facial-image scraping, real-time biometric ID in public for law enforcement without authorisation, and biometric categorisation inferring sensitive attributes). Source: https://artificialintelligenceact.eu/annex/3/
Critical infrastructure (area 2)Annex III
  • AI used as safety components in road-traffic management systems
  • AI in management or operation of water, gas or heating distribution
  • AI safety components in electricity-grid or digital-infrastructure management
Covers AI that is a safety component in, or manages/operates, critical infrastructure. The Article 6(3) filter may apply to purely administrative or monitoring tools that do not directly affect safety. Source: https://artificialintelligenceact.eu/annex/3/
Education & vocational training (area 3)Annex III
  • AI determining access or assignment to educational or vocational institutions
  • AI assessing or evaluating learning outcomes
  • AI evaluating a person's learning level
  • AI monitoring or proctoring students during exams
Covers AI that determines or materially influences educational access or assessment. AI that merely recommends learning resources or provides study aids may qualify for the Article 6(3) filter exception. Source: https://artificialintelligenceact.eu/annex/3/
Employment & workers management (area 4)Annex III
  • AI for recruitment and selection of candidates (screening CVs, shortlisting)
  • AI making or substantially influencing decisions on promotion or termination
  • AI monitoring and evaluating employee performance or behaviour
  • AI allocating tasks to workers (including gig workers)
One of the most compliance-relevant areas for enterprise deployers. HR software vendors offering AI-assisted screening, performance management or workflow automation should assess this area carefully. Source: https://artificialintelligenceact.eu/annex/3/
Access to essential private & public services (area 5)Annex III
  • Credit-scoring and creditworthiness evaluation AI (excluding fraud detection)
  • AI assessing eligibility for public benefits or social services
  • AI for life insurance or health insurance risk assessment and pricing
  • Emergency service dispatch and triage AI
Credit scoring and insurance risk assessment are the highest-profile commercial use cases here. These also trigger the Article 27 FRIA requirement for deployers. Fraud-detection AI is excluded from the credit-scoring entry. Source: https://artificialintelligenceact.eu/annex/3/
Law enforcement (area 6)Annex III
  • AI assessing the risk of a person committing an offence or re-offending
  • AI polygraph and similar lie-detection tools
  • AI evaluating reliability of evidence in criminal investigations
  • AI profiling individuals in the context of criminal investigations
Narrow sector - primarily relevant to law-enforcement authorities and vendors supplying them. Some uses may overlap with Article 5 prohibitions (predictive policing based solely on profiling). Source: https://artificialintelligenceact.eu/annex/3/
Migration, asylum & border control (area 7)Annex III
  • AI polygraph or lie-detection tools used in migration/asylum contexts
  • AI assessing risk of irregular migration or other risks
  • AI examining or deciding on asylum, visa or residence permit applications
  • AI detecting or recognising persons at borders
Primarily relevant to government/border-control authorities and vendors supplying them. High sensitivity given fundamental rights implications for applicants. Source: https://artificialintelligenceact.eu/annex/3/
Administration of justice & democratic processes (area 8)Annex III
  • AI tools that assist judges or judicial authorities in researching, interpreting or applying the law
  • AI used to influence election or referendum outcomes
  • AI targeting voters based on political preferences or behaviour
Very narrow. Pure legal-research tools that help lawyers find relevant case law may qualify for the Article 6(3) filter if they perform preparatory tasks without replacing judicial judgement. Electoral AI uses raise the most severe fundamental-rights concerns. Source: https://artificialintelligenceact.eu/annex/3/
Medical devices & IVDsAnnex I product
  • AI clinical decision-support software used as a safety component in a medical device (MDR/IVDR)
  • AI-enabled diagnostic imaging analysis classified as a medical device
