What is the primary objective of ISO 37301?

ISO 37301 specifies requirements for establishing, implementing, maintaining, and improving an effective Compliance Management System (CMS). Published on 13 April 2021, it replaces the guidance-only ISO 19600 by introducing certifiable 'shall' requirements, following the High-Level Structure (HLS) and Plan-Do-Check-Act (PDCA) cycle to systematically identify compliance obligations, assess risks, and foster a culture of integrity.

Who is legally or professionally required to comply with ISO 37301?

No organization is legally required to comply with ISO 37301, as it is a voluntary certifiable standard applicable to all sizes and sectors. It is professionally adopted by organizations seeking third-party certification to demonstrate systematic compliance risk management, particularly in regulated industries facing ESG pressures, with accreditation available via bodies like ANAB.

Does ISO 37301 require an external audit or third-party certification?

ISO 37301 enables but does not require external audits or third-party certification. Certification is optional through accredited bodies (e.g., ANAB-accredited), involving initial conformity assessment and surveillance audits in a typical three-year cycle, providing verifiable evidence of CMS effectiveness to stakeholders.

How often should an assessment for ISO 37301 be performed?

ISO 37301 requires continual performance evaluation, including internal audits at planned intervals and management reviews at regular planned times. Monitoring, measurement, and analysis occur ongoing via KPIs, with risk-based internal audits and management reviews feeding into the PDCA cycle for continual improvement; certification involves annual surveillance audits.

What are the consequences of non-compliance with ISO 37301?

Non-compliance with ISO 37301 itself carries no direct penalties, as it is voluntary, but certification withdrawal or failure to maintain CMS exposes organizations to regulatory fines, litigation, and reputational damage. It increases risks of unmet compliance obligations, lacking mitigating evidence in enforcement actions.

Can ISO 37301 be mapped to other international frameworks?

Yes, ISO 37301 follows the High-Level Structure (HLS), enabling seamless mapping and integration with other ISO management system standards. Its PDCA-based clauses on context, leadership, planning, support, operation, evaluation, and improvement align directly, supporting Integrated Management Systems (IMS) without referencing specific other frameworks.

What is the first step to begin implementing ISO 37301?

The first step for implementing ISO 37301 is determining the context of the organization, including internal/external issues and interested parties' expectations. This informs CMS scope, obligation identification, and risk assessment per Clause 4, securing top management buy-in before building a centralized compliance register.

What is the primary objective of AS9120B?

AS9120B establishes quality management system requirements for aerospace distributors that procure, store, split, and resell parts without altering characteristics. Built on ISO 9001:2015's 10-clause structure, it adds over 100 IAQG-specific controls targeting distribution risks like traceability loss, counterfeit parts, documentation errors, and external provider weaknesses. Core focus: chain-of-custody integrity via configuration management, preservation, and counterfeit prevention.

Who is legally or professionally required to comply with AS9120B?

AS9120B applies to stockist distributors, pass-through distributors, and those performing batch splitting in aviation, space, and defense supply chains. It targets organizations handling aerospace parts without modification; excludes value-added activities altering conformity or MRO. Certification is not legally mandated but commercially required by OEMs and primes for supply chain approval, with ~2,442 global certifications (836 U.S.) as of March 2026 enabling OASIS visibility.

Does AS9120B require an external audit or third-party certification?

AS9120B requires third-party certification through accredited bodies for formal recognition and OASIS listing. Organizations conduct internal audits per Clause 9.2 at planned intervals, but certification involves Stage 1 (documentation) and Stage 2 (implementation) audits per AS9101, followed by annual surveillance and triennial recertification to verify QMS effectiveness.

How often should an assessment for AS9120B be performed?

AS9120B mandates internal audits at planned intervals to cover all processes annually, plus management reviews at defined intervals. Clause 9.2 requires audit programs ensuring objectivity; Clause 9.3 ties reviews to performance data like nonconformities, supplier trends, and risks. External surveillance audits occur yearly post-certification, with full recertification every three years.

What are the consequences of non-compliance with AS9120B?

Non-compliance with AS9120B risks commercial exclusion from OEM supply chains, loss of OASIS listing, and supply chain liabilities. Auditors issue major nonconformities for gaps in traceability, counterfeit controls, or supplier evaluation, potentially delaying certification. Operationally, it leads to nonconforming outputs, recalls, and eroded customer trust; no direct legal penalties but exposes to contract breaches and safety liabilities.

Can AS9120B be mapped to other international frameworks?

AS9120B aligns directly with ISO 9001:2015's high-level structure, enabling seamless mapping of its 10 clauses. It augments ISO baseline with aerospace additions (e.g., Clause 8 counterfeit prevention, traceability), supporting integrated QMS without other standards. IAQG tools facilitate clause-by-clause comparisons for gap analysis.

What is the first step to begin implementing AS9120B?

Conduct a formal gap analysis against AS9120B clauses using cross-functional teams to map current processes. Per Clause 4, document context, interested parties, scope, and "not applicable" justifications (e.g., 8.3 design); prioritize distributor risks like supplier controls and traceability to build a risk register and implementation backlog.
