The Supply Chain Due Diligence Act: A Complete Guide to Corporate Compliance

The Supply Chain Due Diligence Act (known in Germany as the Lieferkettensorgfaltspflichtengesetz or LkSG) has fundamentally transformed corporate accountability. As we navigate 2026, companies are no longer just responsible for their immediate operations; they are legally bound to uphold strict human rights and environmental standards across their entire global supply networks.

This comprehensive guide breaks down exactly what the law entails, who it affects, and how companies can successfully leverage modern technology to ensure seamless compliance.

Understanding the Supply Chain Due Diligence Act

At its core, the Supply Chain Due Diligence Act mandates that companies actively monitor, identify, and mitigate risks related to human rights violations and environmental degradation throughout their supply chains.

In today’s hyper-globalized economy, supply chains have become highly complex and occasionally opaque. Historically, critical issues like forced labor, child labor, and severe environmental damage could go unnoticed without strict regulatory oversight. This legislation forces businesses to shine a light on these blind spots, transitioning from passive observation to active, transparent risk management across all tiers of their supply chain.

Who Are the Obligated Companies?

The scope of the German Supply Chain Due Diligence Act applies to enterprises that have their central administration, principal place of business, statutory seat, or branch office in Germany.

The criteria for compliance have expanded over time:

• Since 2023: Companies with at least 3,000 employees in Germany.

• Since 2024: The threshold was lowered to encompass companies with at least 1,000 employees in Germany.

Note: The employee count includes both part-time and full-time staff, calculated on a full-time equivalent basis.

7 Core Obligations Under the Act

Companies falling under the jurisdiction of the Supply Chain Due Diligence Act must embed comprehensive due diligence into their corporate governance. The primary obligations include:

1. Effective Risk Management: Establish an active risk management framework to identify and mitigate environmental and human rights risks within internal operations and at direct suppliers.

2. Continuous Risk Analysis: Conduct regular assessments to evaluate both actual and potential negative impacts on human rights and environmental standards.

3. Preventive Measures: Implement robust policies and procedures within your own business and mandate similar standards for direct suppliers.

4. Remedial Action: Act swiftly to correct any adverse impacts your company has caused or contributed to. This includes clear steps to cease, prevent, or minimize the damage.

5. Grievance Mechanisms: Deploy a secure, accessible whistleblowing and complaint system that allows affected individuals to report violations safely and without fear of retaliation.

6. Documentation & Reporting: Maintain transparent records of all risk management activities and publish an annual report detailing your due diligence efforts.

7. Indirect Supplier Due Diligence: If a company obtains “substantiated knowledge” of a violation by an indirect supplier, it must immediately take appropriate measures to address the issue.

Sanctions for Non-Compliance

Failing to comply with the Supply Chain Due Diligence Act carries severe consequences that can paralyze a business financially and operationally:

• Substantial Fines: Companies can face penalties of up to 2% of their average annual global turnover (for enterprises generating over €400 million annually). For other non-compliance issues, fines can reach up to €8 million.

• Exclusion from Public Contracts: Violators can be blacklisted and barred from participating in public procurement processes in Germany for up to three years.

• Strict Enforcement Actions: The Federal Office for Economic Affairs and Export Control (BAFA) is empowered to conduct sudden audits, demand information, and heavily investigate company records.

• Increased Civil Litigation Risk: While the Act doesn’t create direct civil liability in German courts for overseas violations, it establishes a legal baseline. Affected parties are increasingly leveraging these obligations in civil lawsuits.

• Severe Reputational Damage: Mandatory public reporting means non-compliance will quickly reach consumers and investors, destroying brand trust.
