The LkSG and the CSDDD are two different levels of legislation
The Supply Chain Due Diligence Act is German law which applies directly. It obliges covered companies to manage human rights and certain environmental risks in an appropriate manner. The obligations apply in stages to the company’s own business operations, its direct suppliers and, where there is substantiated knowledge, also to its indirect suppliers. However, the Act does not require that every violation in a global supply chain be prevented. Rather, it requires effective, risk-based due diligence management that is tailored to the extent of influence, the nature of the contribution and the severity of the risk.
The CSDDD is an EU directive that must first be transposed into national law. The original Directive (EU) 2024/1760 was substantially amended by Directive (EU) 2026/470, which entered into force on 18 March 2026. For companies established in the EU, the key threshold now stands at more than 5,000 employees and a global net turnover of over 1.5 billion euros. The ultimate parent companies of such groups, as well as certain franchise and licensing arrangements, may also be covered. For companies from third countries, separate criteria apply, which are linked to the turnover generated within the Union.
The two regimes are similar in their underlying risk-based approach, but do not overlap in terms of either their scope of application or their reach. Thus, a company may currently be subject to the LkSG without subsequently falling within the narrower personal scope of the CSDDD. Conversely, international groups may be covered by the CSDDD even though the German entity alone does not meet the LkSG threshold.
