ISO 9001 2026 September 16: What to Prepare Now
What Certification Bodies Will Do on Publication Day
Stay Current
ISO expects the next edition in September 2026. Get source-checked weekly briefings.
Major certification bodies — BSI, DNV, SGS, Bureau Veritas, TÜV SÜD, NQA, LRQA, and others — have been preparing for the ISO 9001:2026 publication for months. On and immediately after publication day, certified organizations can expect:
Formal notification: Certification bodies will notify all ISO 9001:2015 certificate holders. The notice will confirm the publication of ISO 9001:2026. It will state the transition timeline. They will explain how to schedule the transition audit.
Updated audit protocols: Certification bodies will use updated audit protocols that include ISO 9001:2026 requirements. All new certifications after September 16, 2026 will be to ISO 9001:2026.
Transition audit scheduling: Certification bodies will begin scheduling transition audits for existing certificate holders. Most bodies plan to include the transition audit within regular surveillance. Or they will include it in recertification audits. This approach will minimize disruption and extra cost.
What Certified Organizations Should Do Now
Organizations that have not begun transition planning have six weeks until publication. Act now to start transition planning. Minimum preparation before the transition audit includes these actions: Conduct a gap analysis against the new requirements. Update the context analysis to include climate change. Review the quality policy and the management reviewmanagement review/glossary#management-review process for quality culture evidence. Restructure the risk register to match the new Clause 6.1 structure. Train internal auditors on the new requirements.
For most organizations with a mature ISO 9001:2015 implementation, this preparation can be completed in 20–60 hours of internal effort. Organizations that have not yet started should allocate this time before the end of September 2026.
Action Required
Contact your certification bodycertification body/glossary#certification-body now to understand their transition audit process and timeline. Ask specifically: (1) Will the transition audit be conducted as part of my next regular audit? (2) What additional audit time will be required? (3) What evidence will you expect to see for the new Clause 5.1.1 and Clause 4.1 requirements?

Frequently Asked Questions
Can I still get certified to ISO 9001:2015 after September 16, 2026?
No. Certification bodies will not issue new ISO 9001:2015 certificates after publication of ISO 9001:2026. All new certifications starting September 16, 2026 will be to ISO 9001:2026.
What if my ISO 9001:2015 certificate expires before I complete the transition?
Certificates expiring before the transition audit require a full initial audit to ISO 9001:2026. This process costs more and takes more time. Organizations should schedule the transition audit before their certificate expiry date.
Will there be a grace period after September 2029?
No. The IAF transition timeline is mandatory with no grace period. Organizations not completing transition by September 2029 will have certificates withdrawn.
