The world's most widely held management-system standard has been refreshed. ISO published the sixth edition, ISO 9001:2026, on 16 September 2026 — the date ISO/TC 176/SC 2 fixed when it approved the final draft on 7 August. The transition is confirmed: Global ACI's transition requirements give certified organisations until 30 September 2029 to move across, and from 31 March 2028 new certifications are to the 2026 edition only.
The headline for anyone running a quality system: this is an evolution, not a rebuild. The clause structure stays the same. The process approach and the Plan-Do-Check-Act backbone are unchanged. If your 2015 system is genuinely working, the gap to 2026 is manageable — and most of it can be closed inside your normal management-review and internal-audit rhythm.
What is actually changing
These are the areas that carry real, confirmed change:
- Climate change in your context (4.1 and 4.2). Already in force since the 2024 amendment. You must determine whether climate change is a relevant issue for your organisation, and record that decision — even if the answer is "not relevant to our scope".
- Quality culture and ethics (5.1.1). Top management is now explicitly expected to promote and demonstrate a quality culture and ethical behaviour, with a light evidence trail to show it.
- Awareness (7.3). That culture-and-ethics expectation extends to all staff, not just the quality policy and objectives.
- Risk and opportunity, separated (6.1). The clause is restructured so that managing risk and pursuing opportunity are documented distinctly, introducing "opportunity-based thinking" alongside the familiar risk-based thinking.
- Management of change, strengthened (6.3). The existing change-planning clause adds expectations to communicate changes, monitor their effectiveness, and review the results — closing the loop between planning a change and confirming it worked.
- A much expanded Annex A. ISO 9001:2015's short informative Annex A explained its structure and terminology; the 2026 edition replaces it — and the old Annex B — with a far more extensive clarifying annex: word meanings, applicability, and a section for every clause from 4 to 10. It adds no new requirements and contains no worked examples, but it will shape how auditors interpret the standard.
We unpack each of these in its own article — see the links below.
Two more items complete ISO's own list of six changes. Twenty core quality-management terms now appear directly in clause 3, rather than only by reference to ISO 9000 — convenient, though notably the word "opportunity" is still left undefined despite the new emphasis on opportunity-based thinking. And the old Annex B is removed, its references to other standards folded into Annex A and the bibliography. Neither changes what you must do, but both are worth knowing so the published document holds no surprises.
One thing the change lists do not mention, which your clause map will: clause 10 is renumbered. The published edition has no 10.3 — the 2015 clauses 10.1 and 10.3 are folded into a single 10.1, continual improvement, and 10.2 is now the last clause. Management review (9.3) also gains an explicit input — changes in the needs and expectations of interested parties — weighs risks and opportunities as two separate verdicts, and its outputs are now called results. Same work, different numbers: re-point your cross-references and your management-review agenda when you transition. We cover the clause-3 point in Terms now in clause 3 — and the one that's missing.
What is not changing
It is worth being equally clear about what the 2026 edition does not introduce, because there is a lot of noise about it. There is no new mandatory requirement for AI governance, ESG reporting, supply-chain resilience, remote auditing, or digital documentation. Clause 8 (operations) sees only minor wording tweaks. Be sceptical of anyone using the revision to sell you a full system overhaul — the changes do not justify it.
A sensible plan from here
The only change that is already mandatory today is the climate amendment. Start there, fold the rest into your next management-review cycle, and you will be comfortably ahead.
Want it clause by clause instead of by theme? The free 2015 vs 2026 comparison covers every clause of ISO 9001 across both editions.
Start with three things: add a documented climate-change assessment to your 4.1 context; put quality culture and ethics on your management-review agenda with minutes that actually reference them; and run a gap assessment against the published text. Then split your risk and opportunity records, add ethics to induction and awareness training, and bring the new topics into your internal-audit scope.
If you would like the gap sized properly — clause by clause, with a prioritised close-out plan rather than a generic checklist — the ISO 9001:2026 Transition Toolkit is built for exactly that — Version 2.0 is aligned to the published text.
Written against the approved final draft of ISO 9001:2026 and public committee updates. Checked against the published text of ISO 9001:2026 (SANS 9001:2026 Ed. 6, the identical South African adoption) on 27 September 2026. Updated 23 September for publication and the confirmed transition dates; updated 27 September after the published-text check — the clause 10 renumbering, the management-review changes, and Annex A described as it is.
