- ISO 9001:2026 was published on 16 September 2026. The official Bulgarian translation, BDS EN ISO 9001:2026, has been in force since 24 September 2026 and can already be purchased from the Bulgarian Institute for Standardization (BDS).
- ISO 9001:2015 certificates remain valid until 30 September 2029. By that date, all certified organizations must transition to the new edition.
- From 31 March 2028, initial certifications will be carried out against ISO 9001:2026 only.
- The transition can take place at a scheduled surveillance audit, at recertification or at a separate transition audit.
- The changes are mostly clarifications. The main new points are that risks and opportunities are managed separately, quality culture and ethical behaviour are now explicit requirements, and the management of change has been expanded.
ISO 9001:2026 is now a reality. On 16 September 2026, the International Organization for Standardization (ISO) published the sixth edition of the world’s most widely used standard for quality management systems. The new edition replaces ISO 9001:2015 and incorporates the 2024 amendment on climate change.
ISO 9001 remains the most widely applied of all management system standards. More than one million certificates have been issued worldwide, in almost every sector and for organizations of every size. This is why each new edition affects a very large number of certified organizations, suppliers and customers across the entire supply chain.
The Bulgarian standard BDS EN ISO 9001:2026 has been in force since 24 September 2026. It is the official Bulgarian-language edition of EN ISO 9001:2026 and supersedes BDS EN ISO 9001:2015 and its amendment BDS EN ISO 9001:2015/A1:2024. The standard can be purchased from the Bulgarian Institute for Standardization.
The structure of the standard is unchanged. Most requirements remain the same in substance, and the changes are mainly clarifications and editorial improvements. The most important are:
The transition deadlines have been set by Global ACI, the international organization formed by the merger of IAF and ILAC:
| Deadline | What it means |
|---|---|
| 31 March 2027 | Accreditation bodies are ready to assess against the new edition. |
| 30 June 2027 | Certification bodies submit their transition declaration to their accreditation body. |
| 30 September 2027 | Accreditation bodies complete their transition decisions for certification bodies. |
| 31 March 2028 | Initial accredited certifications are carried out against ISO 9001:2026 only. |
| 30 September 2029 | End of the transition period. ISO 9001:2015 certificates lose their validity. |

Do I need to take action immediately?
It is not urgent. ISO 9001:2015 certificates remain valid until 30 September 2029. However, the changes take time to implement and to build up evidence, so it makes sense to start early. It is convenient to combine the transition with a scheduled surveillance audit or with recertification.
Will I need an additional audit?
Not necessarily. The transition can take place at a scheduled surveillance audit or at recertification. A separate transition audit is also possible if that suits you better.
Will the audit itself change?
Auditors will look for specific evidence of two things: that risks and opportunities are managed separately, and that quality culture and ethical behaviour are actually practised, not just described in documents.
When can I get certified directly to the new edition?
Accredited ISO 9001:2026 certificates will be issued once the accreditation body has confirmed the certification body’s transition. From 31 March 2028, initial certifications are carried out against the new edition only.
Where can I buy the standard?
The official Bulgarian translation, BDS EN ISO 9001:2026, is sold by the Bulgarian Institute for Standardization. The original English version is sold by ISO.
INCERT is closely following the accreditation process and will inform certified organizations of the specific steps in good time. For questions about the transition to ISO 9001:2026 or about certification, contact us or submit a certification application online.
