What Is ISO Certification?
ISO Certification — Overview
ISO (International Organization for Standardization) is an independent, non-governmental international body that publishes management system, product, and process standards. ISO certification is third-party confirmation by an accredited Certification Body (CB) that an organisation’s management system complies with a specific ISO standard.
In India, ISO Certification Bodies are accredited by the National Accreditation Board for Certification Bodies (NABCB), which operates under the Quality Council of India (QCI). NABCB is a signatory to the International Accreditation Forum (IAF) Multilateral Recognition Arrangement — meaning NABCB-accredited certificates are internationally recognised in 70+ countries.
ISO certification is typically voluntary in India, but is effectively mandatory for GeM portal vendor registration, most government tenders, MNC vendor qualification, export market access, and sector-specific regulatory compliance (CDSCO for medical devices, FSSAI for food, RBI/SEBI for financial services).
All ISO management system certificates have a 3-year validity with mandatory annual surveillance audits in Year 1 and Year 2, and a full recertification audit in Year 3.
⚠️
NABCB Accreditation Matters
Always verify your CB is NABCB-accredited. Certificates from non-accredited CBs are not accepted by government tender committees, export authorities, or MNC procurement teams. TaxClue works exclusively with NABCB-accredited CBs.
