26 July 2029: Application date for in-scope companies under the revised CSDDD

The data layer behind CSDDD compliance is built over multiple procurement cycles. Supplier engagement frameworks, contract clauses and risk methodologies signed today determine what is available when due diligence obligations begin to apply. Companies that already report under CSRD or run national supply chain regulations are using the transition period to consolidate one supplier-data foundation across all relevant regimes.

What the regulation requires

In-scope companies must identify, assess, and address adverse impacts on human rights and the environment across their own operations, subsidiaries, and chain of activities.

The revised scope applies to EU companies with more than 5,000 employees and net worldwide turnover above €1.5 billion, and to non-EU companies generating more than €1.5 billion in EU turnover.

Direct (Tier 1) business partners are the primary focus for due diligence. Evidence of risk in deeper tiers triggers further investigation.

Due diligence obligations cover six areas:

Integrating due diligence into company policy and risk management
Identifying and prioritizing impacts
Preventing and mitigating potential harms
Remediating actual harms
Engaging stakeholders
Operating a grievance mechanism

Member States designate supervisory authorities and set penalties up to 3% of worldwide net turnover.

Operational challenges of CSDDD compliance

Scoping the chain of activities correctly

The revised CSDDD focuses in-depth assessment on direct business partners, with deeper investigation triggered only by plausible information of risk further upstream. Determining which partners are in scope, which trigger points warrant escalation, and how downstream relationships are treated requires a defined methodology applied consistently across the business.
