ISO 9001:2026 vs ISO 9001:2015: Key Changes Explained

ISO 9001:2026 is out. ISO released it on 16 September 2026, and it takes the place of ISO 9001:2015 and the 2024 climate amendment.

If your company in Oman holds a 2015 certificate, you probably want one answer first: is this a big job? For most organizations, no. The clause layout is familiar and your core processes still apply. What has shifted is the detail, and a few of those details deserve attention before your next audit.

Below, the changes are grouped by who they land on: top management, the quality team and operations. The table gives the whole picture first.

The changes at a glance

For top management

Culture and ethics (Clauses 5.1.1 and 7.3)

Leaders now have an explicit job: promote a culture of quality and ethical behaviour. Staff, in turn, must understand what that culture looks like. The idea also appears in a note on the work environment (Clause 7.1.4).

Documents will not prove it. Evidence will come from daily behaviour: whether people report errors early, what a manager does when a shipment is due but a check has failed, and how staff describe their own part in quality when asked.

A simple first step is to ask your supervisors those questions. If the answers are patchy, a short briefing for each team is the quickest fix, and ISO 9001 awareness training is one way to build that awareness.

Interested parties and climate (Clauses 4.2 and 4.1)

Clause 4.2 adds a choice. Once you know who your interested parties are and what they expect, you must state which of those expectations your QMS will meet. Legal requirements and promises already made to customers stay in scope, so this is not an opt-out. An extra column in your existing register can record the decision.

Clause 4.1 asks whether climate change matters to your QMS. The question first appeared in the 2024 amendment, so the 2026 text only absorbs it. In Oman the answer is rarely theoretical. Cyclone Mekunu shut the Port of Salalah in 2018, and Sohar Port paused marine operations just before Cyclone Shaheen arrived in 2021. A storm like that can delay supplies, stop site work and push back customer deliveries.

For the quality team

Risks and opportunities are split (Clause 6.1)

The old Clause 6.1.2 covered actions for both. It now divides into 6.1.2 for risks and 6.1.3 for opportunities, while 6.1.1 still covers identifying both. For each one you analyse, evaluate, act and then check that the action worked. Risk actions should fit what is at stake for the QMS's intended results. A new note flags the danger of being unable to supply conforming products or services during and after a disruption.

A register that only lists threats will look thin. An opportunity needs an owner, an action and a result, just as a risk does. Your current register may still do the job if it shows that chain.

Change planning (Clause 6.3)

Planning a change used to mean four checks: purpose and consequences, QMS integrity, resources, and responsibilities. Three more are added. How will you monitor whether the change worked? How will you tell people about it? When will you review the outcome?

Picture a warehouse operator in Sohar moving to new stock-control software. Before, its plan might stop at process controls and who does what. Now it should also say who is told and when, which figures will show the system is working, and when management will look at the results.

Audits, management review and improvement

• Internal audits (9.2.2): every audit needs its own stated objective, next to scope and criteria. Update your audit plan templates. If auditors need a refresher, see ISO 9001 internal auditor training.
• Management review (9.3.2): add a standing input on shifts in what interested parties need and expect. The results of risk actions and opportunity actions are also shown as separate inputs, and Clause 9.1.3 evaluates them separately too.
• Improvement (10.1): the old Clause 10.3 is gone. Continual improvement now sits in 10.1 and draws on monitoring and measurement results as well as analysis, evaluation and review outcomes. Nonconformity and corrective action stay in 10.2 with light edits. Update clause numbers quoted in your procedures, checklists and review templates.

For operations

Clause 8 is mostly stable. Four updates affect day-to-day work:

• Disruptions (8.2.1): when supply of a product or service is disrupted, give customers relevant information about your contingency actions.
• Changed orders (8.2.4): when a customer changes a requirement, update the related documented information and inform everyone affected.
• Design work (8.3): planning must consider other interested parties, not just customers and users. Outputs must carry the information needed for safe and proper provision.
• Suppliers (8.4.3): brief external providers on the requirements for how they deal with your customers and other interested parties, where relevant.

Knowledge (Clause 7.1.6)

The 2015 text asked you to keep process knowledge on hand. The 2026 text wants it retained, applied and shared so the whole QMS reaches its intended results. The weak spot is know-how held by one or two long-serving people, such as a senior estimator or a maintenance supervisor. Handover notes, job shadowing and a log of lessons learned reduce that exposure.

What stays the same

• The ten-clause layout and the process approach.
• Customer focus, release of products and services, preservation, and control of nonconforming outputs.
• Your document and record names. The wording on documented information was revised, but nothing needs renaming.
• Annex A has been expanded to explain terms and intent. It explains the standard but adds no requirements.

Timeline for certified organizations in Oman

Publication of the new edition does not cancel your current certificate. Global ACI, which sets transition rules for accredited certification bodies, has set these milestones:

• 31 March 2027: accreditation bodies must be ready to assess against ISO 9001:2026.
• 31 March 2028: from this date, new and initial accredited certificates are issued to ISO 9001:2026 only.
• 30 September 2029: the deadline for organizations already certified to ISO 9001:2015.

You can move over at a surveillance or recertification audit, or in a separate transition audit. Certification bodies are still getting ready, so ask yours what it offers and when. Also check that it is accredited by a Global ACI MRA signatory for your scope.
