Last updated: November 2026
ISO 9001:2026 was published on 16 September 2026 and replaces ISO 9001:2015. Under the Global ACI transition rules (TECH-3-TR, issued 4 September 2026), no new ISO 9001:2015 certifications can be issued after 31 March 2028, and every ISO 9001:2015 certificate stops being valid on 30 September 2029. Source: Global ACI transition requirements for ISO 9001:2026. Confirm your own audit dates with your certification body. The clause structure is unchanged, and the new requirements are limited: quality culture and ethical behavior, separate treatment of risks and opportunities, expanded planning of changes, climate change in your context review, and wider awareness requirements. Our transition plan assumes about 20 weeks of part-time work by default for a small or mid-sized company already certified to the 2015 edition. Template version 1.1 (October 2026), checked line by line against ISO 9001:2026 as published on 16 September 2026.

What changed in ISO 9001:2026?
| Clause | What changed | What to do |
|---|---|---|
| 3 Terms | Clause 3 now defines 20 core management system terms. ISO 9000 remains the reference for all other terms. | Check that the terms used in your manual and procedures still match. |
| 4.1 Context | You must determine whether climate change is a relevant issue. | Add a climate relevance assessment to your context review and record the conclusion. |
| 4.2 Interested parties | You decide which interested-party requirements are addressed through the QMS. | Add that decision to your interested parties register. |
| 5.1.1 Leadership | New item i): top management promotes quality culture and ethical behavior. The clause now has 12 items, up from 10. | Define what this means for you and keep evidence of leadership actions. |
| 5.2 Quality policy | Reorganized into 5.2.1 (establishing the policy) and 5.2.2 (communicating it). Substance largely the same. | Check your policy and its communication against the new layout and your strategic direction. |
| 6.1.2 and 6.1.3 | 6.1 now has three sub-clauses: 6.1.1 determining risks and opportunities, 6.1.2 actions to address risks, 6.1.3 actions to address opportunities. | Evaluate and act on opportunities in their own right. Separate lists are a convenient approach, not a requirement. |
| 6.3 Planning of changes | Four items become seven: adds communication of the change, monitoring and evaluation of effectiveness, and review of results. | Extend your change procedure and log to cover the full loop. |
| 7.3 Awareness | New item e): people must be aware of quality culture and ethical behavior. | Update induction and awareness training. Keep records. |
| 8 Operation | Mostly terminology and layout updates, for example externally provided processes, products and services. Item e) of 8.2.1 now refers to information on contingency actions and disruption. | Update terms in your procedures and check 8.2.1 e). No new processes are needed. |
| 9 Performance evaluation | Core requirements retained. The 9.3.2 inputs grow from six to eight. | Add the new topics to your audit checklist and update your management review inputs and agenda. |
| 10 Improvement | 10.1 Continual improvement now merges 10.1 and 10.3 of the 2015 edition. There is no 10.3 in 2026. | Update clause references in your procedures and records. |
| Annex A | Rewritten as informative guidance on structure, terminology and intent. It adds no requirements. The old Annex B is removed. | Read it for the intent of the requirements. |

When is the ISO 9001:2026 transition deadline?
ISO 9001:2026 was published on 16 September 2026. Under the Global ACI transition rules (TECH-3-TR, issued 4 September 2026), no new ISO 9001:2015 certifications can be issued after 31 March 2028, and every ISO 9001:2015 certificate stops being valid on 30 September 2029. Source: Global ACI transition requirements for ISO 9001:2026. Confirm your own audit dates with your certification body. Your certification body sets the practical timetable: when it will start auditing to the 2026 edition, and the last date it will accept a transition audit so there is time to close findings. Ask them now, and consider transitioning at a scheduled surveillance or recertification audit, which may avoid the cost of a special visit. For the full timeline and what transition training covers, see ISO 9001:2026 transition period, deadline and training.
How do you transition to ISO 9001:2026?
- Get the standard and read the changes. The free changes summary gives you the overview.
- Run a gap analysis against the 2026 edition. Use the Gap Analysis Workbook.
- Approve a transition plan with owners and dates. Treat the transition as a planned change under clause 6.3. The transition plan template does the scheduling for you.
- Update clause 4 records: context, climate change relevance and interested parties.
- Address leadership, culture and ethics: policy wording (the Quality Manual Template has 2026-ready policy examples), leadership evidence and awareness training.
- Split risks and opportunities using a risk and opportunity register, and extend your change management process.
- Train people and run an internal audit against the 2026 edition using an updated audit checklist.
- Hold a management review, close actions and book the transition audit.
All of the tools for these steps are in the ISO 9001:2026 templates collection, or together in the Transition Toolkit. Building a system from scratch or replacing an overgrown 2015 system? The Complete QMS Documentation Kit includes the toolkit plus the manual, 20 procedures and 43 forms. See also the complete documentation templates guide.
What did not change?
The harmonized structure with clauses 4 to 10 stays. The process approach, risk-based thinking and the plan-do-check-act cycle stay. Operational clauses are substantively unchanged. The text adds no specific requirements on artificial intelligence, digitalization or supply chain resilience. The standard does not require a quality manual, although most companies keep one; see the quality manual template guide.
How much does the transition cost?
For a company that is already certified, the main cost is internal time. External costs are a copy of the standard, any extra audit time your certification body charges for the transition, and whatever support you buy. Consultants typically quote several thousand dollars for a supported transition. Doing it in-house with templates costs a few hundred dollars at most. See templates vs hiring a consultant for an honest comparison.
Frequently asked questions
Is there an ISO 9001:2026 implementation guide?
Yes. The eight steps above are the implementation sequence for a company already certified to ISO 9001:2015: get the standard, run a gap analysis, approve a plan, update clause 4 records, address leadership and culture, split risks and opportunities, train people and audit internally, then hold the management review and book the transition audit.
What are the ISO 9001:2026 certification requirements?
Certification is decided by your certification body, which audits your system against the requirements of ISO 9001:2026. From 31 March 2028 new certifications can only be issued to the 2026 edition, and ISO 9001:2015 certificates stop being valid on 30 September 2029. The new requirements to be ready for are quality culture and ethical behavior (5.1.1 and 7.3), opportunities handled separately from risks (6.1), the expanded planning of changes (6.3) and the added management review inputs (9.3.2).
How long does the ISO 9001:2026 transition take?
Our plan assumes about 20 weeks of part-time work for a small or mid-sized company already certified to the 2015 edition, plus time to close any audit findings.
What is the ISO 9001:2026 transition period?
It runs from publication on 16 September 2026 to 30 September 2029. See the transition period, deadline and training page for the dates and a week-by-week plan.
Need help with the transition?
Most certified companies can transition in-house with the tools above. If you want independent eyes before your auditor arrives, we offer a fixed-price gap assessment ($1,950), a remote internal audit day ($2,250) or a done-with-you transition (from $5,950). Work is remote by default, with on-site support by arrangement for larger engagements. Consulting does not guarantee certification. Book a free 30-minute scoping call or see the consulting packages.

ISO 9001:2026 transition FAQ
Is ISO 9001:2026 a major revision?
No. It keeps the structure of the 2015 edition and adds or clarifies a limited number of requirements. Organizations that conform to ISO 9001:2015 will not need to restructure their system.
Do we need a new certificate?
Yes. Your certification body will assess your system against the 2026 edition and then reissue your certificate to ISO 9001:2026. Ask it whether it will do this at a scheduled surveillance or recertification audit or at a separate visit.
What happens if we miss the transition deadline?
Under the transition rules set by accreditation bodies, ISO 9001:2015 certificates stop being valid three years after publication (September 2029). After that you would need to be certified to the 2026 edition from scratch. Confirm your own audit dates with your certification body.
Do internal auditors need retraining?
They need to understand the changes and audit against them. Clause 7.2 requires you to determine the competence your people need and keep evidence of it. Our ISO 9001:2026 Internal Auditor course and Transition Masterclass give auditors a documented, certificated update.
Does ISO 9001:2026 affect ISO 13485, IATF 16949 or AS9100?
Not directly. Sector standards based on ISO 9001 are revised on their own timetables. If you hold one of those certificates, follow the guidance of that scheme owner.
