ISO 9001:2026 is the latest version of ISO 9001, the international standard for quality management systems. It was published on 16 September 2026 and replaces ISO 9001:2015. That started a three-year transition period for every organization certified to the 2015 edition.
This page explains what ISO 9001:2026 is, what has changed, how it compares with ISO 9001:2015, and what certified organizations need to do before the transition deadline
What Is ISO 9001:2026?
ISO 9001:2026 is the sixth edition of ISO 9001 certification and the current version of the standard. It sets out the requirements for a quality management system (QMS) that helps an organization consistently meet customer and regulatory requirements and keep improving.
The 2026 edition is a targeted revision, not a rewrite. It keeps the same harmonized 10-clause structure used across ISO management system standards, and the core concepts of ISO 9001:2015 remain: the process approach, the Plan-Do-Check-Act cycle and risk-based thinking. What changes is the emphasis and clarity of certain requirements.
Why Was ISO 9001 Revised?
ISO reviews its standards regularly so that they stay relevant to how organizations operate. In the decade since ISO 9001:2015 was published, organizations have changed how they work: more digital processes, more attention to organizational culture and ethics, faster change, and growing expectations from customers and other stakeholders.
The revision aims to:
- reflect what drives quality in organizations today, especially leadership and culture
- make requirements clearer and easier to apply consistently
- strengthen how organizations manage risks, opportunities and change
- give users better guidance on interpreting the standard
What's New in ISO 9001:2026
The main changes from ISO 9001:2015 are:
- Quality culture and ethical behaviour: These are now built into the requirements, particularly in leadership, awareness and the environment in which processes operate. Top management is expected to promote a culture that supports quality and ethical conduct.
- A clearer distinction between risks and opportunities: The 2015 edition handled them together. The 2026 edition has separate requirements for determining and addressing risks and for determining and addressing opportunities.
- Stronger change management: There are reinforced requirements for planning, communicating, monitoring and reviewing changes to the quality management system.
- Climate change considerations: The 2024 amendment’s requirement to consider whether climate change is a relevant issue is now part of the standard.
- Core terms inside the standard: A limited set of core QMS terms, drawn from ISO 9000, now appears directly in ISO 9001, so the key definitions sit in one place.
- Expanded Annex A: There is more informative guidance on the structure, terminology and intent of the requirements. Annex A explains the requirements but adds no new obligations.
What hasn’t changed: the overall clause structure, the process approach, the PDCA cycle, risk-based thinking, and the focus on customers and continual improvement. An effective ISO 9001:2015 certification system is a strong foundation for ISO 9001:2026.

| Quality culture and ethics | Implied through leadership and engagement | Explicitly built into the requirements |
| Risks and opportunities | Addressed together | Separate requirements for each |
| Change management | Planning of changes required | Reinforced: planning, communicating, monitoring and reviewing changes |
| Climate change | Added by the 2024 amendment | Part of the standard |
| Terms and definitions | Referenced in ISO 9000 | Core terms included in the standard |

ISO 9001:2026 Transition Timeline and Deadline
Certified organizations have three years to move from ISO 9001:2015 to ISO 9001:2026.
| Date | Milestone |
|---|---|
| 16 September 2026 | ISO 9001:2026 published; transition period begins |
| From publication | Transition audits can be scheduled once the certification body is accredited for the new edition |
| Around March 2028 (expected) | New certifications to ISO 9001:2015 expected to end [verify against IAF transition rules] |
| 30 September 2029 | Transition deadline: ISO 9001:2015 certificates expire or are withdrawn |
What this means:
- Your ISO 9001:2015 certificate stays valid during the transition period, so you can choose when to transition.
- The transition audit can usually be carried out with your next surveillance or recertification audit, or separately, ahead of your cycle.
- If you haven’t transitioned by 30 September 2029, your ISO 9001:2015 certificate will no longer be valid.
Plan early. Audit capacity is usually tightest in the final year of a transition window, and organizations that leave it late have less choice over timing. read the ISO 9001:2026 transition guide to know in detail.
What ISO 9001:2015-Certified Organizations Should Do
- Get a copy of ISO 9001:2026 from ISO or your national standards body, and read the changes in full.
- Compare your current QMS with the new requirements, focusing on quality culture, ethics, risks and opportunities, and change management.
- Update your processes and documented information where needed. For example, review how top management promotes quality culture, and how risks and opportunities are each identified and addressed.
- Brief your people. Awareness of quality culture and ethical behaviour now forms part of the requirements.
- Cover the new requirements in an internal audit and management review, so you have evidence that the changes are in place and working.
- Plan the transition audit with your certification body, and decide whether to combine it with your next surveillance or recertification audit.
As a certification body, Guardian audits your system against the new edition. Updating the QMS itself is your organization’s responsibility.
