MD 26 sets key requirements for certification bodies:

Auditor competence: Certification bodies must train auditors for ISO 9001:2026. Auditors must assess quality culture (Clause 5.1.1), climate change context (Clause 4.1), and restructured risk management (Clause 6.1).

Transition audit planning: Certification bodies must provide transition audit plans to ISO 9001:2015 certificate holders. The plan must state when the transition audit will occur. It must state any extra audit time needed.

Certificate validity: ISO 9001:2015 certificates remain valid throughout the transition period. Certification bodies must not withdraw ISO 9001:2015 certificates before the transition ends. Exceptions apply only if the certificate holder requests withdrawal or fails to cooperate.

New certifications: From the publication date of ISO 9001:2026, certification bodies must issue new certificates to ISO 9001:2026. They must not issue new ISO 9001:2015 certificates after this date.

What This Means for Certified Organizations

For organizations currently certified to ISO 9001:2015, MD 26 provides important assurances. Your certificate remains valid until the end of the transition period (September 2029), and your certification bodycertification body/glossary#certification-body is required to contact you with a transition audit plan. You do not need to rush your transition — but you should engage with your certification body to understand their timeline and ensure you have sufficient time to prepare.

Companies planning initial ISO 9001 certification should note this. New certifications will reference ISO 9001:2026 from the publication date. Align implementation with the 2026 requirements, not the 2015 edition.

The transition requirements align with ISO 9001:2026 on ISO.orgISO 9001:2026 on ISO.orghttps://www.iso.org/standard/62085.html, the definitive reference upon publication on September 16, 2026.

What IAF MD 26 Requires: The Full Breakdown

IAF Mandatory Document MD 26 establishes the requirements for accredited certification bodies conducting ISO 9001:2026 transition audits. Understanding what MD 26 requires helps organizations know exactly what their certification body is obligated to assess — and what they need to prepare.

Transition Audit Timing

IAF MD 26 requires transition audits be completed within the 3-year window. The window runs from September 16, 2026 to September 16, 2029. Certification bodies may combine the transition audit with surveillance or recertification audits. This is most cost-effective for companies. Alternatively, companies may request a dedicated transition audit at any time during the window.

Scope of the Transition Audit

The transition audit must cover all clauses where ISO 9001:2026 introduces changes. Based on the FDIS text, the main focus areas are: Clause 4.1 covers climate change consideration. Clause 5.1.1 covers quality culture and ethical behavior. Clause 6.1 covers risk and opportunity analysis and evaluation. Clause 8.2.1 covers contingency communication arrangements. Clause 8.4 covers externally provided processes. Clause 9.1.2 covers multiple customer feedback channels. Clause 9.2 covers defined audit objectives. Clause 9.3 covers management review outputs linked to improvement.

Auditor Competence Requirements

IAF MD 26 requires auditors to complete ISO 9001:2026 transition training. Certification bodies must ensure their auditors can assess the new clauses. Companies can ask certification bodies to confirm auditors completed ISO 9001:2026 training.

Certificate Validity

Existing ISO 9001:2015 certificates remain valid until September 16, 2029. After a successful transition audit, the certification body issues a certificate referencing ISO 9001:2026. The certificate expiry date typically aligns with the existing certification cycle.

What Organizations Must Do Under IAF MD 26

IAF MD 26 sets requirements for certification bodies. Companies also have matching obligations to meet:

  1. Notify your certification body that you intend to transition and agree on a timeline. Most certification bodies require advance notice to schedule transition audits.
  1. Complete a gap analysis against ISO 9001:2026 requirements before the transition audit. The auditor will expect evidence that the organization has assessed the gap and implemented the necessary changes.
  1. Update documented information to reflect the new requirements. This includes quality policy updates (if needed to address quality culture), management review procedures (to address the new output requirements), and supplier management procedures (to address Clause 8.4 changes).
  1. Prepare evidence for the three new requirements: a documented consideration of climate change relevance (Clause 4.1), evidence of leadership behaviors that demonstrate quality culture (Clause 5.1.1), and documented analysis and evaluation of risks and opportunities (Clause 6.1).
