Article 6 — Classification Rules for High-Risk AI Systems

High-Risk Systems SME Relevant ~1 min read · 296 words

Article 6 is the gateway article for the high-risk chapter. It tells you whether your AI system needs to meet the Act’s most demanding compliance requirements — or not. Getting this classification right is one of the most important steps for any business deploying AI.

WHAT THE ARTICLE IS ABOUT

Article 6 establishes the criteria for determining whether an AI system qualifies as “high-risk” under the EU AI Act. This classification triggers a comprehensive set of obligations — from risk management and data governance to human oversight and transparency — so understanding where your system sits is essential before anything else.

WHAT IT SAYS

∙ Route 1 — Safety components: An AI system is automatically high-risk if it is a safety component of a product already regulated under EU harmonisation legislation and requires third-party conformity assessment.
∙ Route 2 — Annex III: An AI system is high-risk if it appears in Annex III — covering eight sensitive areas including biometrics, critical infrastructure, education, employment, and access to essential services.
∙ A notable exception exists: if a system poses “no significant risk” it may escape classification, but this must be documented.

WHO IS AFFECTED

∙ Companies that develop or sell AI systems used in the eight Annex III categories
∙ Companies that deploy third-party AI in regulated contexts — hiring tools, credit scoring, student assessment
∙ Importers and distributors of AI products covered by EU product safety law
∙ Non-EU companies whose systems are used in the EU

WHAT IT MEANS FOR SMES

∙ If you are buying and using a third-party AI tool you are a deployer and may have obligations even though you didn’t build the system
∙ If your AI performs a generic back-office task with no direct impact on people’s rights, you are likely outside high-risk scope
∙ First practical step: check Annex III — if your use case isn’t listed, you’re probably clear
∙ Document your reasoning either way — this protects you in any future regulatory inquiry
