ISO 9001:2026: what changed, the transition dates, and what a plant should do now

Short answer

ISO 9001:2026 is the new edition of the international quality management system standard, published on 16 September 2026. The 2015 edition is superseded, and organisations certified to it have until 30 September 2029 to finish their transition.

The 2026 edition is a revision of the 2015 text, not a new standard. ISO's technical committee describes clearer wording, a stronger focus on leadership, quality culture and accountability, clearer risks and opportunities, and a new Annex A that explains key terms and intent. Your ISO 9001:2015 certificate stays valid during the transition. The dates that matter to a plant are 31 March 2028, when new and initial accredited certifications can only be issued to the 2026 edition, and 30 September 2029, when the move must be finished. The move can happen at a surveillance audit, a recertification audit or a separate transition audit, and your certification body decides how it runs. Write to it now and ask which it offers, and when.

What changed in ISO 9001:2026

ISO/TC 176/SC 2, the technical committee that maintains the standard, announced the publication on its news page. It names five things about the revision: clearer wording, a stronger focus on leadership, quality culture and accountability, a clearer treatment of risks and opportunities, a new Annex A that clarifies key terms and the intent of the requirements, and close alignment with other ISO management system standards. That page is run by a third party, so confirm the details against the standard on iso.org.

Several certification bodies have published their own summaries. Where at least two of them agree, the points below are safe to plan around. Where only one says it, this page leaves it out and you should check the standard.

What changed in ISO 9001:2026, and how well it is confirmed (checked 2026-11-05)
ChangeWhat it means on a plantWho says so
Quality culture and ethical behaviour sit with top managementLeaders have to show, with evidence, that they promote quality culture. Expect auditors to talk to managers, not only read records.ISO/TC 176/SC 2 (leadership, quality culture, accountability); LRQA, DNV and BSI (ethical behaviour)
Risks and opportunities are handled separatelyYour risk register and your improvement ideas need their own treatment, with their own owners and actions.ISO/TC 176/SC 2 (clearer risks and opportunities); LRQA and DQS (separate requirements)

New Annex AGuidance on terms and intent. It is informative, so it adds no new requirement.ISO/TC 176/SC 2; LRQA and DQS (no new obligations)
Process approach, plan-do-check-act and risk-based thinking stay centralThe system you built for 2015 is the starting point. This is a targeted revision, not a rewrite.LRQA and other certification bodies describe it as a targeted update

Not confirmed here: new clause numbers, any move of defined terms into the main text, and any new supply chain or digital requirement. Only single sources mention them. Read the standard before you rely on a number, and do not rewrite procedures around a clause number you have not seen.

The practical reading is simple. If your leaders already run daily management, you are most of the way there. If quality sits with the quality department alone, that is the gap. For the requirements the revision builds on, see ISO 9001 in plain language, which walks the 2015 clauses and keeps their numbering.

ISO 9001:2026 transition dates

The committee's transition guidance gives the dates below. Some dates apply to certification and accreditation bodies, not to you, but they decide when your body can audit to the new edition. Other sources quote slightly different end dates, such as mid-September 2029, so use the date in the transition letter from your own body.

DateWhat happensWhat it means for a plant
16 September 2026ISO 9001:2026 publishedThe transition period starts. Your 2015 certificate is unaffected.
31 March 2027Accreditation bodies ready to assess to 2026Certification bodies can start applying to be approved to audit the new edition.
30 June 2027Certification bodies submit transition declarationsYour body should tell you its plan after this date.
30 September 2027Accreditation body decisions completeYour body should be approved to audit to 2026 by this point.
31 March 2028New and initial accredited certifications only to 2026Applies to organisations being certified for the first time. Ask your body how it treats a recertification after this date.
30 September 2029ISO 9001:2015 certificates valid until this dateYour transition must be finished. It can be at a surveillance, a recertification or a separate audit.

Is ISO 9001:2015 still valid? Do you need a separate transition audit?

Yes. ISO 9001:2015 stays a valid basis for an accredited certificate until 30 September 2029, and your existing certificate remains in force during the transition. Publication of the new edition does not cancel it.

A separate transition audit is optional. The committee says the transition can happen during a scheduled surveillance or recertification audit, or through a separate audit. Combining it with a scheduled audit saves a visit but usually adds audit time, so ask your body for the price and the days in writing. A separate audit gives you control over the date and keeps the surveillance routine. Your certification body decides which routes it offers.

A worked transition timeline

Illustrative. A plant was first certified to ISO 9001:2015 in June 2025. Surveillance audits fall each June, and recertification is due in June 2028. Today is 5 November 2026. The question is which audit to use for the move.

Illustrative: three ways to schedule the move for a plant audited each June
OptionAudit monthMonths from nowMonths before 30 September 2029Main risk
Transition at the 2027 surveillanceJune 2027727Your body may not be approved yet. Its decision date can be as late as 30 September 2027.
Transition at the 2028 recertificationJune 20281915Fits the cycle. Confirm how your body treats a recertification after 31 March 2028.
Separate audit at the latest practical dateJune 2029313Audit capacity is likely tightest at the end. Any major finding leaves little time to close it.

Sums. November 2026 to June 2027 is 7 months, and June 2027 to September 2029 is 27 months, so 7 + 27 = 34 months in total. November 2026 to June 2028 is 19 months and June 2028 to September 2029 is 15 months, so 19 + 15 = 34. November 2026 to June 2029 is 31 months, and June 2029 to September 2029 is 3, so 31 + 3 = 34. The numbers are counted by calendar month, not by day.

For this plant the 2028 recertification is the natural fit, since it leaves 15 months of margin and avoids a separate visit. The 2027 date is only worth chasing if the body confirms it is approved and has auditors for the 2026 edition. The point of the exercise is the same for any plant: put your own audit months into the table, and let the gaps decide.

What a plant should do in the next 12 months

  1. 1

    November to December 2026: get the standard and write to your certification body

    Buy the 2026 edition. Ask your body in writing: which route for your site, which audit month, how many extra audit days, whether it will be approved by your audit date, and what the transition letter says. Keep the reply on file.

  2. 2

    January to March 2027: run a gap analysis

    Read the new text against your system. Mark each requirement met, partly met or not met, with the evidence. Pay attention to leadership evidence, the separate treatment of risks and opportunities, and how changes are planned.

  3. 3

    April to June 2027: update procedures and records

    Change only what the gap analysis showed. Split risk and opportunity records, add a change planning step where one is missing, and keep the version history so an auditor can see what moved. See SOP format and meaning.

  4. 4

    July to September 2027: retrain your internal auditors

    Give auditors the new requirements and Annex A. Rewrite the audit checklist to match, then run one internal audit against the new text. See the ISO 9001 internal audit checklist.

  5. 5

    October 2027: management review and confirm the date

    Use the review to show leaders the gap analysis and the plan, with owners. Confirm the audit date in writing. The management review kit lists the inputs.

Do not stop other work for this. Most of it is evidence your plant already has but has not collected. A training matrix and a closed CAPA record are the kind of evidence an auditor asks for.

Common mistakes in a transition

  • Waiting for the final year. The committee's own dates leave a three year window, and the last months are when auditors are in the shortest supply.
  • Rewriting every procedure. The revision builds on 2015, so change what the gap analysis found.
  • Trusting a clause table from a blog. Single sources disagree on numbering and detail. Buy the standard.
  • Leaving leaders out. The revision puts leadership, culture and accountability at the front, so managers need to be able to explain them to an auditor.
  • Assuming the date on this page is yours. Your certification body sets your audit month and route.

FAQ

Questions about iSO 9001:2026

  1. ISO 9001:2026 was published on 16 September 2026, according to ISO's technical committee for the standard, ISO/TC 176/SC 2. It replaces ISO 9001:2015 as the current edition.

  2. Yes, for now. An accredited ISO 9001:2015 certificate stays valid until 30 September 2029, which is the end of the transition period set by ISO's technical committee. During that time your certificate remains in force, and you transition at a time agreed with your certification body.

  3. Not necessarily. The transition can be done during a scheduled surveillance or recertification audit, or in a separate audit. Which routes are open depends on your certification body, so ask it in writing and ask how many audit days each route adds.

  4. ISO's committee lists clearer wording, a stronger focus on leadership, quality culture and accountability, clearer risks and opportunities, and a new Annex A that explains key terms and intent. Certification bodies add that risks and opportunities are treated separately and that change management is stronger. Check the standard for the exact requirements.

  5. No. According to ISO's committee, 31 March 2028 is the date after which new and initial accredited certifications can only be issued to ISO 9001:2026. Organisations already certified to ISO 9001:2015 have until 30 September 2029 to transition. Ask your certification body how it handles a recertification after 31 March 2028.

  6. This page has not confirmed any 2026 clause numbers, because the standard is paid and certification bodies give different detail. Buy the edition your certification body audits to before you update references. The clause walk on the ISO 9001 guide uses the 2015 numbering.

  7. No. The standard does not require certification, and a plant can follow it without a certificate. A customer contract or tender is the usual reason to certify, and the certificate is then issued by an accredited certification body that audits the plant.
