This report presents the Risk Classification Analysis Service developed at RISE to support early implementation of the EU Artificial Intelligence Act (Regulation (EU) 2024/1689).

The service offers a structured methodology for preliminarily assessing whether AI systems may fall under the Act’s High-Risk category and for identifying related compliance measures.

It combines questionnaire-based information collection, analytical workshops, and preliminary classification, resulting in a final report that documents assumptions, explains the rationale for the classification, highlights compliance gaps, and provides recommendations for preparation toward conformity assessment.

Pilot applications in manufacturing and energy showed that classification outcomes depend strongly on deployment context and on how regulatory criteria are interpreted, particularly when determining whether an AI system falls within an Annex III area, supports critical-infrastructure operation, or functions as a safety component of an Annex I–regulated product.

The report also summarises key findings, challenges and lessons learned from applying the methodology in practice.
