ISO 9001:2026 transition checklist.

Why this checklist has no clause list

Most pages on this subject are built around a table of new and changed clauses. Most of those tables were written from drafts, before the standard was published, and a free page cannot lawfully reproduce the published text. The summaries circulating since spring have contradicted each other on basic points.

We keep a separate page that sorts the claims about the content by how well corroborated each one is, including two specific errors worth knowing about — see what changed in ISO 9001:2026, claims ranked. This page is the other half of the problem: given a published but copyrighted text, and certification bodies that cannot yet audit to it, what should you actually be doing?

The answer is more than nothing and less than a rewrite, and it divides cleanly into three phases.

Now — published, but not yet auditable

From publication until your certification body is accredited for the 2026 edition. Everything here is worth doing whatever your audit date turns out to be.

1. Find your certificate expiry date. This single date drives every other decision you will make about the transition, and most people have to go and look it up. Write it down before you read any further.
2. Confirm the climate amendment is actually in your system. Amendment 1:2024, published February 23, 2024, added climate-change considerations to clauses 4.1 and 4.2, and it applies to your 2015 certificate today. If your context analysis and interested-party register do not address climate, that is a nonconformity now, not a future one.
3. Ask your certification body when their accreditation will cover the 2026 edition. Global ACI gives accreditation bodies until March 31, 2027, to be ready to assess, and certification bodies until June 30, 2027, to submit their transition declarations. Your certification body knows where it sits in that sequence. Ask by email so you have the answer in writing, and ask in the same email whether your transition can ride a scheduled surveillance or recertification audit.
4. Check how modular your documentation actually is. If your quality manual is one long document with clause numbers baked into its structure, any revision is expensive. If your system is a set of process documents that reference the standard loosely, a revision is cheap. Finding out which you are takes an hour, and if the answer is the first one, that is worth fixing regardless.
5. Get the standard and read it before you change anything. ISO sells it, and ANSI sells it in the United States. Read it before you act on anyone's summary, ours included. Most summaries in circulation were written from drafts before publication, and they have contradicted each other all year.
6. Then do a real gap analysis, against the published text. Now that the text exists, a gap analysis means something, provided it is done against the standard itself and not against a draft, a summary or a template. Start with the areas ISO named in its launch release: leadership and a culture of quality, risks and opportunities, and the new section on the intent of the requirements.

Once your certification body can audit you

Global ACI requires accreditation bodies to complete their transition decisions by September 30, 2027. Expect certification bodies to become available one by one before then.

1. Book early, not late. Audit calendars congest badly in the back half of every transition period, because most organizations wait. The cost of being early is a slightly earlier project. The cost of being late is not getting a slot.
2. Fold the transition into a scheduled audit where you can. Global ACI-TECH-3-TR allows the transition to take place at a scheduled surveillance or recertification audit, or through a separate transition audit. Ask your certification body how much audit time it will add either way, and plan around your audit calendar rather than the deadline.
3. Decide which edition your next recertification uses. If your certificate comes up for renewal during the window and your certification body's accreditation covers the new edition, recertifying to the superseded one generally means doing the work twice.
4. Update the system, then run an internal audit against the new text. Auditing your revised system yourself, against the actual standard, before your certification body does it is the cheapest way to find the gaps. See our page on internal audits.

If you are not certified yet

The date that matters to you is March 31, 2028, not 2029.

1. Know your cutoff. From March 31, 2028, new and initial accredited certifications may only be issued to ISO 9001:2026. If your certificate will be issued before then, certifying to the 2015 edition is still open to you, and you transition later like everyone else. Leave margin: audits slip, and corrective actions after an audit take time.
2. Ask about certificate validity before you sign. In previous transitions, certification bodies commonly shortened newly issued certificates to the old edition so they expired at the transition deadline. Global ACI's transition requirements do not address it for this one, so ask your certification body whether a certificate issued in 2027 runs a full three years, and get the answer in writing.

What not to do

Every item here is something we watch organizations spend money on during a revision.

• Do not buy a “2026-ready” template before you have read the standard. A template is somebody else's reading of a copyrighted text. Read the standard first, then decide whether you need a template at all.
• Do not pay for a gap analysis done against anything but the published text. Ask who did the analysis and what they compared you against. If the answer is a summary, a draft or a pre-publication template, it is not a gap analysis of ISO 9001:2026, and you will pay for it twice.
• Do not rewrite your whole manual. Rewrite against the published text, and only the parts that need it. ISO's own guidance on the revision describes it as evolutionary, not revolutionary, and says that for an organization already running an effective 2015 system the transition is not a complete rebuild.
• Do not plan a budget around September 2029. Confirmed as September 30, 2029, by Global ACI-TECH-3-TR, issued September 16, 2026 — but it is not the date that will constrain you. From March 31, 2028, new and initial accredited certifications may only be issued to ISO 9001:2026. All five dates are on our transition tracker.
• Do not assume AI, ESG or supply-chain clauses are coming. Those claims circulate widely, and ISO's own launch summary of the edition mentions none of them. We rank the claims by how well corroborated each one is on a separate page.

The standard published on September 16, 2026, and Global ACI set the transition requirements the same day. We keep the transition tracker current as that develops, and if your question is whether to certify to the 2015 edition now rather than wait, we answer that separately. If you would rather talk it through against your own certificate dates, get in touch — that conversation is free and does not require you to buy anything.

Common questions

Changelog

• 2026-10-03 — Rewritten for the period after publication. The first phase was still headed “before September 16,” two items still told readers to wait for the text and for transition rules that have both existed since September 16, and the gap-analysis advice still said to book it for October. It is now October, the text is published, and the advice has changed accordingly: read the published standard, then gap-analyze against it. Added a phase for organizations not yet certified, built on the March 31, 2028, cutoff.
• 2026-09-09 — Published, one week before the expected publication of ISO 9001:2026. Deliberately contains no clause-by-clause content, because the standard is not published and any such list would be invented. Every action listed is either verifiable from a published source today or edition-independent.
