Annex III High-Risk AI Systems: Article 6 Classification Guide
Article 6 of the EU AI Act defines two pathways to high-risk classification. This guide walks you through both, the Annex III use-case categories, the Article 6(3) exemption, and a step-by-step self-assessment.

Last updated: July 4, 2026
What Makes an AI System High-Risk?
Article 6 creates two independent pathways. Falling under either makes you high-risk — and triggers the full Annex IV documentation, Article 9–15 controls, and conformity assessment obligations.
The two pathways: Article 6(1) covers AI used as safety components in regulated products. Article 6(2) + Annex III covers stand-alone AI in eight specific use-case categories.
Pathway 1: Safety Components (Article 6(1))
If your AI is a safety component of a product covered by EU sectoral legislation (medical devices, vehicles, machinery, lifts, toys, etc.), or is itself such a product, it is automatically high-risk.
Conformity assessment must be conducted by a notified body.
Pathway 2: Annex III Use Cases (Article 6(2))
Eight use-case categories trigger high-risk classification regardless of the underlying technology:
- Biometrics: Remote biometric identification and emotion recognition systems
- Critical Infrastructure: AI in energy, water, gas, heating, and digital infrastructure
- Education: AI for student assessment, exam scoring, and learning analytics
- Employment: CV screening, interview analysis, task allocation, performance evaluation, termination decisions
- Essential Services: Credit scoring, loan approval, insurance pricing, emergency services dispatch
- Law Enforcement: Risk assessment, polygraphs, evidence evaluation, profiling
- Migration & Asylum: Visa applications, asylum processing, border control
- Justice: Sentencing assistance, case outcome prediction, legal research
The Article 6(3) Exemption
An Annex III AI system can be exempted if it does not pose a significant risk to health, safety, or fundamental rights.
Recognized cases include narrow procedural tasks, improving the result of a previously completed human activity, detecting decision patterns without replacing human assessment, or preparatory tasks for a downstream human decision. Profiling is always high-risk. The exemption never applies if the system performs profiling of natural persons.
If you claim the exemption, document the reasoning thoroughly. Regulators may challenge it.
Documentation Requirements If High-Risk
High-risk AI systems must maintain comprehensive compliance documentation:
- Annex IV technical documentation
- Article 9 risk management system
- Article 10 data governance records
- Article 12 logging in production
- Article 14 human oversight design
- Conformity assessment + CE marking
- EU AI database registration
How AIAgentree helps
If your system is high-risk, AIAgentree produces the ongoing evidence that classification triggers:
- Article 12 automatic decision logging — tamper-evident, captured via SDK, MCP, A2A, or the OpenTelemetry bridge with no rewrite
- Article 14 human-oversight and approval workflows that record who overrode what, when, and why
- Audit-fit retention (at least six months) plus Annex IV-aligned exports for your technical file, with EU data residency (Germany)
Frequently Asked Questions
How do I know if my AI system is high-risk under Annex III?
Work through the two Article 6 pathways: (1) your system is a safety component of a product covered by the EU legislation in Annex I, or (2) it falls into one of the Annex III use cases (biometrics, critical infrastructure, education, employment, essential services, law enforcement, migration, justice). If either applies and no Article 6(3) exemption holds, it is high-risk.
What is the Article 6(3) exemption?
An Annex III system can avoid high-risk status if it does not pose a significant risk to health, safety, or fundamental rights — for example narrow procedural tasks or preparatory work for a human decision. Profiling of natural persons is always high-risk, and you must document your exemption reasoning because regulators can challenge it.
When do high-risk obligations start applying?
For stand-alone Annex III high-risk systems, full obligations apply from August 2, 2026. AI that is a safety component of products regulated under existing EU sectoral law reaches full applicability on August 2, 2027.
What happens once my system is classified high-risk?
You must implement Article 9 risk management, Article 10 data governance, Article 11/Annex IV technical documentation, Article 12 logging, Article 14 human oversight, complete a conformity assessment, affix CE marking, and register in the EU database. AIAgentree covers the logging, oversight, and audit-evidence portion of that stack.
