High-Risk AI Systems Under the EU AI Act
The EU AI Act classifies certain AI use cases as high-risk. If your system falls into one of these categories, you inherit a long list of obligations before you can lawfully place it on the EU market.
The Annex III categories in plain English
- Biometric identification and categorisation of natural persons
- Management of critical infrastructure (energy, water, traffic)
- Education and vocational training (admissions, scoring, proctoring)
- Employment (recruitment, task allocation, performance evaluation)
- Access to essential private and public services (credit scoring, benefits, insurance)
- Law enforcement, migration, border control, administration of justice
- Democratic processes (e.g. influencing elections)
Core obligations for providers
- Risk management system across the full lifecycle
- Data and data governance — representative, relevant, free of errors
- Technical documentation (Annex IV) kept up to date
- Record-keeping — automatic logging of events
- Transparency and information to deployers
- Human oversight designed into the system
- Accuracy, robustness, cybersecurity with declared performance metrics
- Quality management system covering the whole organisation
- Conformity assessment, CE marking, EU database registration
- Post-market monitoring and incident reporting
Where most teams underestimate the effort
- Building an actual data governance process (not a slide)
- Producing Annex IV technical documentation at the level regulators expect
- Designing human oversight that is meaningful, not cosmetic
- Setting up post-market monitoring with real telemetry
If your product touches HR, credit, health, education, insurance, or public services — assume high-risk until proven otherwise, and start building the evidence trail now.
