What Is the ISO 37301 Compliance Management System?
ISO 37301 is an international standard published by the International Organization for Standardization (ISO) in 2021 that provides a framework for establishing, implementing, and maintaining a Compliance Management System (CMS). It replaced the earlier ISO 19600 guideline and was upgraded to a certifiable requirements standard, enabling organizations to obtain third-party certification.
How It Differs from ISO 37001 and the Integration Trend
While ISO 37001 focuses specifically on anti-bribery management, ISO 37301 covers all compliance domains—antitrust, data privacy, environmental regulations, labor laws, and more. Since 2025, a growing number of organizations have pursued integrated certification for both standards. According to the Korean Standards Association (KSA), ISO 37301 certifications in Korea grew by 42% year-over-year in 2025.
Rapid Adoption in Korea in 2026
Major Korean conglomerates including KG Group, Hanwha Solutions, and POSCO International have obtained ISO 37301 certification in recent years, and they are now requiring their entire supply chains to strengthen compliance capabilities. KG Group, in particular, declared a group-wide commitment to compliance management in late 2025 and recommended that key suppliers establish formal compliance systems.
Why SMEs Need ISO 37301
Increasing Supply Chain Compliance Requirements
As large corporations expand their ESG management practices, compliance assessments of tier-1 and tier-2 suppliers have become standard procurement criteria. Companies like Samsung Electronics and Hyundai Motor evaluate whether suppliers maintain a compliance management system. ISO 37301 certification is the most effective way to provide objective proof.
Regulatory Penalty Mitigation
Korea's Fair Trade Commission grants up to a 20% reduction in penalties for companies operating a voluntary compliance program (CP). Courts also consider the existence of a compliance management system as a mitigating factor during sentencing. ISO 37301 offers an internationally recognized framework that delivers stronger risk mitigation than a standalone CP.
ESG Due Diligence and Global Credibility
The EU Corporate Sustainability Due Diligence Directive (CSDDD), which took effect in 2024, requires companies operating in the European market to conduct human rights and environmental due diligence across their supply chains. ISO 37301 certification serves as a powerful tool to demonstrate compliance capabilities internationally when engaging with global buyers.
Core Requirements of ISO 37301 Certification
Identifying Compliance Obligations and Risk Assessment
Organizations must systematically identify all legal, regulatory, and contractual obligations and assess each one for likelihood and impact of non-compliance. For SMEs, this process typically reveals 50 to 80 compliance obligations, all of which must be regularly updated and monitored.
Establishing Compliance Functions, Responsibilities, and Authority
PDCA-Based Continuous Improvement
ISO 37301 operates on the Plan-Do-Check-Act cycle:
A Practical Roadmap for SMEs
Step-by-Step Implementation Strategy
| Phase | Duration | Key Activities |
|-------|----------|----------------|
| Phase 1: Gap Analysis | 1–2 months | Regulatory landscape review, gap analysis, risk assessment |
| Phase 2: System Design | 2–3 months | Policy and procedure development, organizational setup, training design |
| Phase 3: Operation | 3–4 months | Pilot operation, internal audit, management review |
| Phase 4: Certification Audit | 1–2 months | Stage 1 (document review) + Stage 2 (on-site audit) |
For a typical SME, the entire process takes 7 to 11 months, with total costs (including consulting) ranging from KRW 20 to 50 million (approximately USD 15,000–38,000).
Leveraging Government Support Programs
By leveraging these programs, SMEs can reduce their actual costs by more than 50%.
