On September 16, 2026, the International Organization for Standardization (ISO) published ISO 9001:2026, the sixth edition of the world’s best-known quality management system standard. The new edition replaces ISO 9001:2015 after more than a decade.
ISO 9001 is used by organizations around the world to establish, operate and continually improve quality management systems. The publication of ISO 9001:2026 therefore marks the beginning of a new transition period for organizations already certified to ISO 9001:2015, as well as for businesses planning certification in the coming years.
What happened?
The revision of ISO 9001 has been under development for several years.
The Final Draft International Standard, ISO/FDIS 9001, successfully passed the final approval vote in 2026, after which the document moved into the publication stage.
On September 16, 2026, ISO 9001:2026 was officially published and became the new international edition of ISO 9001, replacing ISO 9001:2015.
This is the first full revision of ISO 9001 since 2015.
Before publishing this article, confirm that the official ISO page shows the standard as Published and verify the final publication date and edition details.
What has changed in ISO 9001:2026?
ISO 9001:2026 does not abandon the familiar quality management system model.
The process approach, the PDCA cycle, customer focus, risk-based thinking, performance evaluation and continual improvement remain central to the standard.
The revised edition instead strengthens and clarifies several areas that have become increasingly important over the past decade.
Among the most visible themes are quality culture, a stronger connection between leadership and quality, clearer treatment of risks and opportunities, greater attention to the active use of opportunities, more visible consideration of ethical behaviour, integration of climate-related provisions introduced through the 2024 amendment, and additional explanations intended to make certain requirements easier to interpret consistently.
The key message for certified organizations is important:
ISO 9001:2026 is an evolution of ISO 9001:2015, not a requirement to rebuild the entire quality management system from scratch.
Quality culture becomes more visible
One of the most notable themes in the revised standard is quality culture.
A quality management system can have policies, objectives, procedures, records and performance indicators and still operate poorly if day-to-day behaviour does not support quality.
ISO 9001:2026 places more emphasis on whether leaders and employees actually demonstrate the behaviours that support the intended results of the QMS.
In practice, organizations may need to look more closely at how employees report problems, how managers respond to nonconformities, whether improvement is encouraged, and whether quality objectives influence real business decisions.
This does not necessarily mean creating a separate “quality culture policy.” Culture cannot be demonstrated by documentation alone.
Risks and opportunities are addressed more clearly
Risk-based thinking remains one of the foundations of ISO 9001.
The revised edition makes the distinction between risks and opportunities more visible.
The practical management questions are different:
Risk: What could prevent us from achieving the intended result, and what will we do to reduce the likelihood or impact?
Opportunity: What could help us achieve a better result, and what will we do to make use of that opportunity?
For many organizations, this will be a good reason to review existing risk registers.
If opportunities currently appear only as a formal column in a spreadsheet, the transition to ISO 9001:2026 may be an opportunity to connect them with real improvement actions.
Climate change is not entirely new
Climate change should not be presented as a completely new ISO 9001:2026 requirement.
In 2024, ISO had already published ISO 9001:2015/Amd 1:2024, which introduced climate-related considerations into the existing edition.
Organizations should therefore first check whether they have already considered the relevance of climate change within their organizational context and the requirements of relevant interested parties.
The revised edition incorporates this topic into the updated standard.
What happens to ISO 9001:2015 certificates?
The publication of ISO 9001:2026 does not mean that ISO 9001:2015 certificates immediately become invalid.
Organizations already certified to ISO 9001:2015 will be given a transition period.
During that period, certified organizations will have time to update their quality management systems and complete the transition to the new edition in accordance with the applicable international transition requirements.
Important publication-day check
Before publishing this article, verify whether the final international transition requirements have already been issued.
If they have not yet been published, keep the following wording:
At the time of publication of this article, the detailed international transition requirements have not yet been finalized. Audit Advisor will update this article as soon as the official transition period, deadlines and audit arrangements are confirmed.
If they have been published, replace that paragraph with the confirmed transition period, final deadline and any relevant requirements for certification bodies and certified organizations.
I would not state that the transition period is three years unless the final official transition document confirms it.
Do organizations need to rewrite their entire QMS?
No.
The publication of a new ISO 9001 edition does not make an existing QMS obsolete.
For organizations already certified to ISO 9001:2015, the most practical starting point is a Gap Analysis.
A Gap Analysis should identify which requirements have genuinely changed, which new expectations are already being met, where actual gaps exist, which processes need adjustment, which documented information should be updated, whether employee training is required, and what changes should be incorporated into internal audit and management review.
A successful transition is not about rewriting every procedure.
It is about changing the system where the new edition genuinely requires a different approach.
What should certified organizations do now?
Organizations should first obtain and review the final published text of ISO 9001:2026.
They can then compare the new requirements against their existing quality management system and develop a practical transition plan.
A sensible sequence is:
- review the final ISO 9001:2026 text;
- perform a Gap Analysis against the current QMS;
- identify affected processes and responsibilities;
- update only the documented information that actually needs to change;
- train relevant employees where necessary;
- implement and monitor the changes;
- verify implementation through internal audit and management review;
- coordinate the transition audit with the certification body.
There is no reason to make large-scale changes before understanding the final requirements.
What does ISO 9001:2026 mean for organizations in the United States?
For U.S. organizations, ISO 9001 remains an international standard, but accredited certification is delivered through certification bodies working within the relevant accreditation system.
Many U.S. organizations use certification bodies accredited by ANAB or another internationally recognized accreditation body.
The publication of ISO 9001:2026 does not necessarily mean that every certification body can immediately issue accredited certificates to the new edition.
Certification bodies will need to complete the applicable transition and accreditation arrangements.
Organizations planning certification or recertification should therefore verify not only that a certification body offers ISO 9001 certification, but also whether its accreditation status covers the new edition at the time the audit is performed.
What does ISO 9001:2026 mean for organizations in the United Kingdom?
In the United Kingdom, UKAS accredits certification bodies that provide management system certification, including ISO 9001 certification.
As the transition progresses, UK organizations should confirm that their certification body has completed the necessary transition arrangements and is able to issue accredited certification to ISO 9001:2026.
Organizations and customers can also use UKAS CertCheck to verify UKAS-accredited management system certificates.
As in the United States, publication of the standard and availability of accredited certification to the new edition may not happen on exactly the same day.
Should organizations delay ISO 9001 certification because of the new edition?
Not necessarily.
An organization that currently needs ISO 9001 certification for a customer requirement, supplier qualification, tender, contractual obligation or internal business objective should not automatically postpone certification simply because a revised edition has been published.
The correct decision will depend on the applicable transition rules and the readiness of the selected certification body.
For some organizations, certification to ISO 9001:2015 followed by a later transition may still be appropriate.
For others, certification directly to ISO 9001:2026 may become possible once certification bodies have completed the necessary transition arrangements.
Audit Advisor is tracking the ISO 9001:2026 transition
Audit Advisor has created a continuously updated information hub dedicated to ISO 9001:2026.
We will track the publication of official transition requirements, accreditation-body guidance, certification-body transition arrangements, deadlines for certified organizations, audit practices, and practical implementation issues.
The section will also include detailed materials on quality culture, risks and opportunities, Gap Analysis, transition audits, documentation changes and what auditors may focus on under the revised edition.
What happens next?
The publication of ISO 9001:2026 is an important milestone, but it is only the beginning of the transition process.
Organizations certified to ISO 9001:2015 do not need to rebuild their QMS overnight.
The practical priorities are to understand the final requirements, wait for confirmed transition rules where necessary, perform a Gap Analysis and develop a focused transition plan.
Audit Advisor will continue updating its ISO 9001:2026 materials as new official information becomes available from ISO, Global Accreditation Cooperation, ANAB, UKAS and other relevant accreditation bodies.
