different types of iso certification

The most popular types of ISO certification in India include ISO 9001 for quality, ISO 14001 for environment, ISO 45001 for safety, ISO 27001 for data security, and ISO 22000 for food safety. Indian businesses typically apply for 7 to 10 ISO standards based on their sector and operations, choosing from a wide range of internationally recognized benchmarks.   

The International Organization for Standardization (ISO) has published over 25,000 ISO international standards to help businesses meet globally recognized benchmarks. Each ISO certification covers a specific area such as quality, safety, environment, energy, or information security. Indian companies apply for these through accredited certification bodies after a third-party audit process.

This guide covers the 10 most important types of ISO certification, their applications, costs, and benefits. It also includes a quick comparison table, industry-specific recommendations, and key factors that help businesses choose the right ISO standard for their operations in 2026.

Key Takeaways

  • The International Organization for Standardization (ISO) has published over 25,000 different types of ISO certification, but Indian businesses commonly apply for around 7 to 10 standards.
  • ISO 9001, ISO 14001, ISO 45001, ISO 27001, and ISO 22000 are the most popular ISO certifications adopted across Indian industries in 2026.
  • Each ISO certification covers a specific area, such as quality, safety, environment, energy, information security, or food safety.

The 10 Most Adopted ISO Standards in India for 2026 

The 10 ISO standards listed below are the most widely adopted by Indian businesses:  

1. ISO 9001:2015: Quality Management System (QMS)

ISO 9001:2015 is the world’s most widely adopted Quality Management System standard, with more than one million certificates issued across 189 countries. The current version is ISO 9001:2015, supported by Amendment 1:2024, which introduces climate change considerations. ISO has scheduled the revised ISO 9001:2026 for publication in September 2026.

The standard helps businesses improve product and service quality through documented processes and continual improvement. It reduces errors, rework, and customer complaints while improving operational consistency. ISO 9001 also strengthens eligibility for government tenders, large corporate contracts, and international business opportunities.

2. ISO 14001:2026: Environmental Management System (EMS)

ISO 14001:2026 is the latest international standard for Environmental Management Systems. It replaced the 2015 edition, and organizations have until April 2029 to complete the transition to the updated requirements.

The standard provides a structured framework to help businesses manage their environmental responsibilities and improve environmental performance over time. It:

  • Supports compliance with environmental laws
  • Reduces waste and emissions
  • Helps organizations achieve measurable environmental goals

The 2026 edition also places greater emphasis on climate change, biodiversity, and life-cycle thinking.

3. ISO 45001:2018: Occupational Health and Safety (OH&S) Management System

ISO 45001:2018 is the international standard for Occupational Health and Safety (OH&S) Management Systems. It replaced OHSAS 18001 and follows the Plan-Do-Check-Act (PDCA) approach to support continual improvement. The standard is widely used in construction, manufacturing, mining, logistics, and other industries where workplace safety is a priority.

ISO 45001 requires organizations to:

  • Identify workplace hazards across all operations and job roles.
  • Assess health and safety risks through a structured process.
  • Implement controls to eliminate or reduce identified risks.
  • Monitor and review safety performance through regular audits.

The standard helps businesses reduce workplace accidents, injuries, and legal risks. It also improves compliance with safety requirements and strengthens eligibility for construction projects, infrastructure contracts, and government tenders.

4. ISO/IEC 27001:2022: Information Security Management System (ISMS)

ISO/IEC 27001:2022 was published in October 2022, with Amendment 1:2024 on climate considerations. It replaces the 2013 version and adds 11 controls for cloud security, threat intelligence, and secure coding. With cybercrime rising, the standard helps organizations manage information security risks proactively.

ISO 27001 protects data confidentiality, integrity, and availability through structured controls applied across IT, banking, fintech, and healthcare.

The standard reduces breach exposure, ransomware damage, and legal liability after security failures. It unlocks enterprise deals and cross-border partnerships that demand credible data protection.

5. ISO 22000:2018: Food Safety Management System (FSMS)

ISO 22000:2018 is the international standard for Food Safety Management Systems. It replaced the 2005 edition and combines food safety management with the principles of Hazard Analysis and Critical Control Points (HACCP). The standard applies to every stage of the food supply chain, including farmers, manufacturers, processors, distributors, and food service businesses.

ISO 22000 helps businesses identify and control food safety risks before products reach consumers. It reduces the risk of food contamination, product recalls, and foodborne illnesses. The certification also improves customer confidence and supports access to export markets and global food supply chains.

6. ISO 13485:2016: Medical Devices Quality Management System

ISO 13485:2016 is the international quality management standard for the medical devices industry. It applies to manufacturers, distributors, and service providers involved in medical devices and related products. The standard covers product design, manufacturing, traceability, post-market monitoring, and regulatory documentation.

ISO 13485 helps businesses maintain product quality, improve patient safety, and comply with regulatory requirements. It also supports access to international markets, including regions that follow the EU Medical Device Regulation and the US FDA requirements.

7. ISO 50001:2018: Energy Management System (EnMS)

ISO 50001:2018 is the international standard for Energy Management Systems. It helps organizations improve energy performance by managing and reducing energy consumption. The standard requires businesses to establish an energy policy, set measurable energy goals, and regularly monitor energy use. Manufacturing units, commercial buildings, and other energy-intensive facilities commonly implement this standard.

ISO 50001 helps businesses reduce energy costs, improve operational efficiency, and lower their environmental impact. It also supports sustainability reporting and strengthens eligibility for green financing opportunities.

8. ISO 22301:2019: Business Continuity Management System (BCMS)

ISO 22301:2019 sets requirements for a BCMS that prepares organizations for disruptions like natural disasters, cyberattacks, power failures, and supply chain breakdowns. Banks, IT firms, government agencies, and critical infrastructure operators commonly adopt it.

ISO 22301 reduces revenue loss, customer churn, and reputation damage from extended downtime. It strengthens eligibility for banking contracts and IT outsourcing deals.

9. ISO/IEC 20000-1:2018: IT Service Management System (ITSMS)

ISO/IEC 20000-1:2018 is the international standard for IT Service Management Systems. It provides a framework for planning, delivering, monitoring, and improving IT services. IT service providers, managed service providers, and technology companies use this standard to deliver reliable and consistent services.

ISO 20000-1 helps businesses improve service quality, reduce service disruptions, and increase customer satisfaction. It also strengthens credibility and supports opportunities for larger outsourcing projects and government IT contracts.

10. ISO 37001:2025: Anti-Bribery Management System (ABMS)

ISO 37001:2025 is the latest international standard for Anti-Bribery Management Systems. It replaces the 2016 edition and provides a framework to help organizations prevent, detect, and address bribery. The standard includes requirements for anti-bribery policies, risk assessments, due diligence, employee training, and reporting procedures.

ISO 37001 helps businesses reduce the risk of bribery, legal penalties, and reputational damage. It also demonstrates ethical business practices, builds trust with stakeholders, and improves eligibility for government tenders and international business opportunities                   

Which Type of ISO Certification is Right for Your Industry?

The right ISO certification depends on the kind of business you run and the industry you operate in. Below is a clear breakdown of the most useful ISO certifications for each major sector in India:

  • Manufacturing: ISO 9001, ISO 14001, ISO 45001, and ISO 50001 together cover quality, environment, safety, and energy efficiency for any production setup.
  • Healthcare and Pharmaceuticals: Hospitals, pharma firms, and device makers apply for ISO 13485, ISO 9001, and ISO 27001 to cover quality, devices, and patient data.
  • Food and Beverage: ISO 22000 is the core standard for food safety, often paired with ISO 9001 to strengthen quality control across the supply chain.
  • IT and Software: Tech companies, SaaS startups, and IT firms rely on ISO 27001 for data security and ISO 20000-1 for service delivery.
  • Construction: Construction and engineering firms hold ISO 9001, ISO 14001, and ISO 45001 together to meet quality, environment, and safety requirements in major tenders.
  • Logistics and Transportation: Logistics firms start with ISO 9001 and ISO 14001, then add ISO 22301 when supply chain continuity becomes critical.

How Multiple ISO Certifications Strengthen Your Business?

Many Indian businesses today hold two or more ISO certifications, such as ISO 9001, ISO 14001, ISO 45001, and ISO 27001, together through an Integrated Management System (IMS). This works because all modern ISO standards share a common High-Level Structure (Annex SL), which uses the same clauses for leadership, planning, support, operations, and improvement.

Holding multiple ISO certifications through an IMS offers the following real benefits:

  • Reduced Documentation by 30 to 60%: A unified system removes duplicate policies, manuals, and records across standards. One policy framework replaces three or four separate document sets.
  • Lower Audit Costs: Certification bodies offer combined audits for IMS holders. One audit cycle covers multiple standards, which cuts down audit days, internal preparation time, and external fees.
  • Stronger Risk Management: A single integrated risk register captures quality, environmental, safety, and information security risks together. This gives leadership a complete view instead of fragmented data from separate teams.
  • Higher Tender Eligibility: Many government tenders, PSU contracts, and global procurement teams require two or three ISO certifications together. Holding them as a set strengthens your bid against single-certified competitors.
  • Better Operational Consistency: Teams follow one shared process for audits, corrective actions, training, and reporting. This removes confusion across departments and improves accountability.
  • Stronger Client and Investor Trust: International buyers, large corporates, and investors view multiple certifications as a sign of mature operations. This builds credibility during procurement, due diligence, and partnership talks.
  • Easier Indian Regulatory Compliance: Combined ISO certifications often align with Indian laws such as FSSAI, BIS, factory safety rules, and the DPDP Act, 2023. One integrated system covers most regulatory areas at once.
