Run this gate before any material change to qualified certificate issuance, certificate profiles, CA hierarchy, QSCD handling, revocation/status services, repository publication, subcontracted service components, or termination planning. Under the amended eIDAS Article 24, a QTSP must inform its supervisory body at least one month before changing the provision of a qualified trust service and at least three months before it intends to cease those activities.
The review should decide whether the event is only a CP/CPS maintenance item, an assessment item, a subscriber or relying-party notice item, or an Article 24 notification. Commission Implementing Regulation (EU) 2025/2530 identifies significant changes to service descriptions, policies, practice statements, terms, architecture, hosting, cryptography, registration, governance, termination, financial resources or insurance, trusted-list data, and third-party arrangements. The notice must describe the change, planned date and time, reasons and supporting evidence where applicable, and updated documents where applicable. The supervisory body may request more information or a conformity-assessment result and may condition permission to implement an intended change. Confirm the national submission channel with the qualified-service compliance owner.
