Supply Chain Due Diligence Requirements.
Supply Chain Due Diligence Requirements
1. Meaning and Concept
Supply Chain Due Diligence (SCDD) refers to the systematic process by which companies identify, prevent, mitigate, and account for risks arising from their supply chains. These risks include:
- Human rights violations (forced labor, child labor)
- Environmental harm
- Corruption and bribery
- Data protection and cybersecurity risks
SCDD is now a core element of corporate governance and ESG compliance, moving from voluntary practice to mandatory legal obligation in many jurisdictions.
2. Legal and Regulatory Framework
(a) International Standards
- UN Guiding Principles on Business and Human Rights (UNGPs)
- OECD Due Diligence Guidance for Responsible Business Conduct
(b) National and Regional Laws
- Modern Slavery Acts (UK, Australia)
- Duty of Vigilance Law (France)
- Supply Chain Due Diligence Act (Germany)
- Emerging EU Corporate Sustainability Due Diligence Directive (CSDDD)
(c) India
- Companies Act, 2013 (CSR obligations)
- SEBI’s Business Responsibility and Sustainability Reporting (BRSR)
3. Core Elements of Due Diligence
(1) Risk Identification
- Mapping supply chains
- Identifying high-risk regions and sectors
(2) Risk Assessment
- Evaluating likelihood and severity of harm
(3) Risk Mitigation
- Supplier codes of conduct
- Contractual obligations
- Capacity-building measures
(4) Monitoring and Auditing
- Periodic supplier audits
- Third-party verification
(5) Reporting and Disclosure
- Public transparency reports
- Regulatory filings
(6) Remediation Mechanisms
- Grievance redress systems
- Compensation and corrective actions
4. Key Legal Issues
(1) Scope of Duty of Care
- Whether companies owe duties to:
- Workers in supply chains
- Communities affected by suppliers
(2) Extraterritorial Liability
- Liability for actions occurring outside the company’s home jurisdiction
(3) Standard of Due Diligence
- What constitutes “adequate” due diligence?
- Courts assess reasonableness and effectiveness, not just formal compliance
(4) Enforcement and Penalties
- Civil liability
- Administrative fines
- Reputational damage
(5) Contractual vs. Tort Liability
- Breach of supplier agreements
- Negligence claims
(6) Access to Justice
- Victims often face barriers in:
- Jurisdiction
- Evidence
- cost of litigation
5. Key Case Laws
Below are important judicial decisions shaping supply chain due diligence obligations:

7. Challenges in Implementation

The future of SCDD lies in robust governance frameworks, enforceable legal standards, and global cooperation, ensuring that businesses operate responsibly across complex international supply chains.
