EU AI Act Full Enforcement
Enterprise Compliance Checklist

EU AI Act took effect August 2, 2026. Covers high-risk AI compliance, CE marking, documentation, and cross-border challenges for non-EU firms.

High-Risk AI System Compliance Requirements

August 2, 2026 marks the full enforcement of the EU AI Act. Prohibited practices (such as social scoring and real-time remote biometric identification) took effect in February 2025. The provisions now in force cover the Act's core scope — the full compliance obligations for high-risk AI systems.

High-risk AI systems span eight domains including employment screening, credit assessment, education admissions, law enforcement support, and critical infrastructure management. Before deploying such systems, organizations must complete a conformity assessment covering risk management, data governance, technical documentation, transparency obligations, human oversight design, and accuracy and robustness requirements. Non-compliant high-risk AI systems are barred from the EU market.

CE Marking and Technical Documentation Checklist

High-risk AI systems must undergo a conformity assessment and obtain CE marking before being placed on the market. This requires a complete technical documentation package: system architecture description, training data provenance and quality records, model evaluation reports, logging mechanisms, human oversight interface design, and post-market monitoring plans.

Conformity assessment can be completed via internal control (Annex VI) or through a Notified Body. Biometric high-risk AI systems require Notified Body assessment. The CE mark is not just a market access credential — it is the basis for post-market surveillance by EU authorities. Companies should maintain document version control to ensure technical documentation stays current throughout the system lifecycle.

Cross-Border Challenges for Non-EU Firms

For non-EU companies, the EU AI Act presents unique cross-border compliance challenges. First, the Act uses a market access jurisdictional principle — if an AI system's output is used within the EU, the provider falls under the Act regardless of location. This means non-EU firms selling AI products to EU customers must meet all compliance requirements.

Second, an Authorized Representative must be established within the EU to liaise with regulators and maintain technical documentation. Third, high-risk AI systems must be registered in the EU database. These requirements impose substantial organizational, legal, and documentation burdens. Non-EU firms should initiate compliance gap assessments early, budgeting 6 to 9 months for preparation.
