EU AI Act Risk Classification

Classify AI systems under Regulation (EU) 2024/1689 and determine obligations by role.

Important: This skill provides compliance workflow support, not legal advice. Always cite specific EU AI Act articles. Where facts are incomplete, state assumptions explicitly and ask targeted follow-up questions.

Classification Workflow

Follow this decision tree strictly in order. Stop at the first match.

Step 1 — Scope Check

Confirm the AI system falls within scope:

• Is it placed on the market or put into service in the EU?
• Who is the provider, deployer, importer, distributor, or authorized representative?
• Does a territorial or subject-matter exclusion apply (military, national security, pure research)?

If out of scope, document why and stop.

Step 2 — Gate 1: Prohibited Practices (Article 5)

Check every Article 5 category. If any match → PROHIBITED. Stop unless a narrow law enforcement exception applies.

Categories (check all eight):

1. Manipulation/deception causing significant harm
2. Exploitation of vulnerabilities (age, disability, socio-economic)
3. Social scoring with disproportionate/unrelated adverse treatment
4. Individual predictive policing based solely on profiling
5. Untargeted facial image scraping for recognition databases
6. Emotion recognition in workplace/education (narrow exceptions)
7. Biometric categorisation inferring sensitive characteristics
8. Real-time remote biometric identification in public spaces for law enforcement (narrow exceptions)

→ For the complete checklist with examples and edge cases, read references/prohibited-practices.md.

Step 3 — Gate 2: High-Risk (Annex I + Annex III)

Annex I path: Is the AI a product or safety component under EU harmonisation legislation (e.g., MDR, Machinery Regulation) subject to third-party conformity assessment? → HIGH-RISK

Annex III path: Does the intended purpose fall within one of the eight high-risk use-case categories?

→ For all categories with examples and edge cases, read references/high-risk-annex-iii.md.

Article 6(3) exception: Even if an Annex III use case matches, a system is NOT high-risk if it:

• performs a narrow procedural task,
• improves the result of a previously completed human activity,
• detects decision patterns without replacing human assessment, or
• performs a preparatory task for an assessment listed in Annex III,

AND the system does not pose a significant risk of harm to health, safety, or fundamental rights.

If claiming this exception, document the reasoning thoroughly.

Step 4 — GPAI Models (Articles 51–56)

Independent of system-level risk. A minimal-risk app can use a GPAI model with its own obligations. Downstream providers/deployers must still verify vendor evidence and ensure documentation is sufficient for their specific use case and risk profile.

Check:

• Is a general-purpose AI model involved (broad capability, not narrow-purpose)?
• Who is the GPAI model provider vs. downstream provider?
• Does the model meet systemic risk thresholds (compute-based criteria or EU AI Office designation)?

→ For GPAI obligations and systemic risk details, read references/gpai-obligations.md.

Step 5 — Gate 3: Limited Risk (Article 50)

If not prohibited or high-risk, check Article 50 transparency duties:

• AI-generated content or interaction → disclose AI involvement
• Deepfakes/synthetic media → label or watermark
• Emotion recognition systems → inform affected individuals
• Biometric categorisation → inform affected individuals

Step 6 — Default: Minimal Risk

No AI Act-specific obligations. Recommend:

• AI literacy training (horizontal obligation under the Act)
• Security and privacy by design
• Proportionate documentation for auditability
• Voluntary codes of conduct

Quick Question Set

Use these questions at the start (and whenever facts are missing) to gather the information needed for classification. For borderline cases or uncertainty, escalate early to qualified legal counsel and document assumptions.

System & Purpose

1. What does the AI system do? What are its inputs and outputs?
2. What is the intended purpose? What decisions does it support or make?

Impact & Context 3. Does it make or materially influence decisions about individuals in education, employment, essential services, law enforcement, migration, or justice? 4. Who is affected — customers, employees, citizens, patients? 5. Is it customer-facing? Is there meaningful human oversight in practice?

Technical 6. Does it use biometrics, emotion recognition, or infer sensitive attributes? 7. What data categories are processed, including special category data? 8. Is a GPAI model used? Which provider? What compliance evidence is available?

Organisational 9. Who is the provider vs. deployer? Where is it deployed? 10. Is it a product or safety component under EU harmonisation legislation?

If answers are incomplete, state assumptions explicitly and flag gaps.

Load these as needed based on the classification result:

Output Format

Every classification produces three deliverables:

1. Classification Memo — Formal assessment documenting the decision tree walkthrough, classification result, cited articles, and key assumptions. This is the primary legal record.

2. Risk Register Entry — Structured entry for the organisation's AI risk register with system name, classification, key obligations, deadlines, and responsible parties.

3. Executive Summary — One-page summary for leadership with classification result, key obligations, timeline, and recommended next steps.

Always consider horizontal obligations such as AI literacy/training (Article 4) as part of the compliance roadmap, even for minimal-risk systems.

→ For complete templates, read references/templates.md.

Penalties Overview

Flag these in every assessment to ensure appropriate escalation:

For SMEs and startups, the lower of the two amounts applies.
