ISO 9001 Certification

Notice

ISO 9001:2026 was published by ISO on 16 September 2026. The transition period follows IAF resolutions and is expected to be 36 months; contact TÜV NORD Vietnam for information on transition audits.

What is ISO 9001?

Published by the International Organization for Standardization (ISO), ISO 9001 sets out the requirements for a quality management system (QMS). It is designed for organisations of every type and size, from manufacturers to service providers. The current edition, ISO 9001:2026, was published on 16 September 2026 and replaces ISO 9001:2015. It follows ISO's Harmonized Structure with ten clauses; the requirements sit in clauses 4 to 10: context of the organisation, leadership, planning, support, operation, performance evaluation and improvement.

For senior management, ISO 9001 is more than a certificate. It is a strategic tool for building a clear, results-oriented way of working that can contribute to productivity, customer satisfaction and business performance. The standard rests on quality management principles such as customer focus, leadership, engagement of people, the process approach, improvement and evidence-based decision making.

Who should seek ISO 9001 certification?

A quality management system to ISO 9001 suits companies of any size, operating domestically or internationally, that want to demonstrate management capability and performance. A key strength is that it applies to every industry. In practice, companies typically pursue ISO 9001 certification when:

  • Customers, partners or tender documents require suppliers to hold a certified QMS.
  • They are preparing to export or join international supply chains.
  • Rapid growth calls for standardised processes and clearly defined responsibilities.
  • They want a foundation for adding other standards such as ISO 14001 or ISO 45001.

The PDCA cycle and risk-based thinking

ISO 9001 is built on the Plan-Do-Check-Act cycle, applied both to individual processes and to the management system as a whole across your value chain:

  • Plan: set objectives, processes and the resources needed.
  • Do: implement what was planned.
  • Check: monitor, measure and evaluate results.
  • Act: take action to improve.

Since the 2015 revision, and continuing in the 2026 edition, the emphasis has been from paperwork to the results and effectiveness of processes. Organisations have more freedom in how they implement the system, for example through electronic or web-based documentation, and are expected to identify risks and opportunities proactively rather than react once problems occur.

What's new in ISO 9001:2026?

ISO 9001:2026 does not replace the quality management framework; it clarifies and strengthens the requirements to reflect today's operating environment. Notable changes include:

  • Climate change: the requirement to determine whether climate change is a relevant issue in the organisation's context – introduced by amendment ISO 9001:2015/Amd 1:2024 – is now part of the standard's text.
  • Leadership, quality culture and ethical behaviour receive greater emphasis, including in the awareness requirements for staff.
  • Risks and opportunities are distinguished and clarified so they feed into planning and decision making.
  • Management of change is clarified: planning, communicating, monitoring and evaluating changes.
  • Data, information and organisational knowledge play a stronger role in evidence-based decisions.
  • A new Annex A explains concepts, terms and the intent of the requirements.

Organisations certified to ISO 9001:2015 must transition within the period set by the International Accreditation Forum (IAF), expected to be 36 months from publication; the exact deadline follows the IAF's official transition guidance. Thanks to the shared Harmonized Structure, ISO 9001 still combines easily with environmental, energy or occupational health and safety management systems.

Frequently asked questions

Which companies need ISO 9001 certification?
ISO 9001 certification is voluntary and suits any organisation regardless of size or sector, including manufacturing and services. Companies usually seek it when customers, foreign partners or tenders require it, or when they want independent confirmation that their quality management system works effectively.
How long is an ISO 9001 certificate valid?
In line with international practice, an ISO 9001 certificate is valid for three years. During that period the certification body carries out regular surveillance audits, usually once a year, to confirm the system is still effective. A recertification audit before expiry starts the next three-year cycle.
What does an ISO 9001 certification audit look at?
Auditors examine internal processes, responsibilities and authorities, as well as processes involving customers and business partners. The focus is on evidence that the system is actually applied and delivers results, for example quality objectives, internal audits, management review and corrective actions.
Can ISO 9001 be combined with other standards?
Yes. Through the common Harmonized Structure (formerly High Level Structure), ISO 9001 shares its clause framework and terminology with ISO 14001, ISO 45001, ISO 50001 and many other management system standards. You can build one integrated management system and have several standards audited together, saving time and resources.
Is my ISO 9001:2015 certificate still valid now that ISO 9001:2026 is published?
Yes, during the transition period. ISO 9001:2026 was published by ISO on 16 September 2026 and replaces ISO 9001:2015. Certificates to the 2015 edition remain valid until the end of the transition period set by the IAF, expected to be 36 months from publication. Review your system internally against the new requirements, update documentation, train your people and agree the transition audit timing with your certification body.
