Introduction: Why Substance of Concern Tracking Matters Under the ESPR

The Ecodesign for Sustainable Products Regulation (EU Regulation 2024/1781) places significant emphasis on the tracking and reporting of substances of concern present in products sold on the EU market. This is not merely an extension of existing chemical safety regulations like REACH, it represents a new paradigm where substance information must be transparently communicated throughout the value chain and made accessible to consumers, recyclers, and regulators through Digital Product Passports.

For businesses manufacturing, importing, or selling physical products in the EU, understanding these substance of concern obligations is essential. Failure to accurately track and report can result in market access restrictions, financial penalties, and reputational damage. This article provides a comprehensive guide to what the ESPR requires and how businesses can prepare.

What Qualifies as a Substance of Concern Under the ESPR?

The ESPR takes a broad approach to defining substances of concern, going beyond the traditional focus on substances of very high concern (SVHCs) under REACH. Under the regulation, a substance of concern includes any substance that negatively affects the reuse or recycling of materials in the product, any substance classified as hazardous under the CLP Regulation, substances identified as SVHCs under REACH, and substances that may be restricted or subject to specific conditions under future delegated acts.

This expanded definition is deliberate. The ESPR aims to support the circular economy by ensuring that materials can be safely recovered and reused. Substances that compromise recyclability or contaminate waste streams are therefore captured even if they are not currently restricted for health or safety reasons. The EU Circular Economy Action Plan provides the broader policy context for this approach.

Delegated acts for specific product categories may further expand or refine the list of substances that must be tracked, meaning businesses need to monitor regulatory developments relevant to their product range continuously. The practical implication is that a substance which is currently permitted without disclosure may become reportable under a future delegated act, requiring businesses to maintain flexible and comprehensive substance tracking systems rather than static compliance lists.

Reporting Obligations: What Information Must Be Provided?

The ESPR requires that substance of concern information be included in the Digital Product Passport for each applicable product. This information must be sufficiently detailed to enable safe handling, informed purchasing decisions, and effective end-of-life processing.

At a minimum, businesses will need to report:

• The chemical name and unique identifier (e.g., CAS number) of each substance of concern present
• The concentration of the substance within the product or specific components
• The location of the substance within the product (which component or material contains it)
• Safe handling and disposal instructions related to the substance
• Information relevant to recycling and material recovery processes
• Any applicable regulatory classifications or restrictions

This level of detail represents a significant step beyond existing SCIP database reporting under the Waste Framework Directive. Businesses that have already established SCIP reporting processes will have a foundation to build on, but additional data collection and structuring will be required to meet ESPR standards. The requirement to specify the location of substances within products is particularly demanding, as it requires component-level knowledge that many businesses currently lack, especially for complex assembled products sourced from multiple suppliers.

Integration with Digital Product Passports

Substance of concern data must be integrated into the Digital Product Passport in a structured, machine-readable format. This enables automated processing by waste management and recycling operators, allowing them to identify and segregate materials containing problematic substances before they enter recycling streams.

The DPP framework ensures that substance information travels with the product throughout its lifecycle, from point of sale through use, repair, and eventual end-of-life treatment. This is a fundamental shift from the current situation where substance information is often buried in safety data sheets that rarely reach downstream operators.

For businesses, this means substance of concern data must be accurate, up-to-date, and formatted according to the technical standards being developed for DPPs. Our guide to Digital Product Passports explains the data structure and technical requirements in detail.

Supply Chain Challenges in Substance Tracking

One of the most significant practical challenges of substance of concern tracking is obtaining reliable data from complex, multi-tier supply chains. Many businesses, particularly importers and brand owners, have limited visibility into the chemical composition of components and materials sourced from sub-tier suppliers.

Key challenges include:

• Suppliers in non-EU countries may not be subject to equivalent chemical disclosure requirements
• Proprietary formulations and trade secret protections can obstruct full disclosure
• Complex products with hundreds of components require systematic data collection across multiple supplier tiers
• Data quality and reliability varies significantly between suppliers and regions
• Legacy products and existing stock may lack the substance data required for new compliance obligations

Addressing these challenges requires a proactive approach to supplier engagement. Businesses should be incorporating substance disclosure requirements into supplier agreements, conducting material testing where supplier data is unavailable, and investing in supply chain transparency platforms that facilitate data sharing. See our ESPR compliance checklist for a structured preparation approach.

Relationship with REACH, CLP, and the SCIP Database

The ESPR's substance of concern requirements do not replace existing obligations under REACH, the CLP Regulation, or SCIP database reporting. Instead, they complement and extend these frameworks by requiring substance information to be communicated more transparently and in a more accessible format through Digital Product Passports.

Businesses that are already compliant with REACH and SCIP requirements will find that much of the data they need for ESPR compliance is already being collected. However, the ESPR demands a different level of granularity and accessibility. SCIP reporting, for example, focuses on articles containing SVHCs above 0.1% by weight, whilst the ESPR may require reporting on a broader range of substances at different thresholds depending on the relevant delegated act.

The regulatory landscape for chemical substances in products is becoming increasingly integrated. Businesses that take a holistic approach to substance data management, rather than treating each regulation in isolation, will achieve greater efficiency and resilience. A unified substance database that serves REACH, CLP, SCIP, and ESPR reporting needs simultaneously is far more cost-effective than maintaining separate compliance processes for each regulatory framework.

Enforcement and Consequences of Non-Compliance

Market surveillance authorities will verify substance of concern reporting as part of their ESPR enforcement activities. This may involve physical testing of products, auditing of technical documentation, and cross-referencing DPP data with known substance databases.

Inaccurate or incomplete substance reporting can trigger product recalls, market access restrictions, financial penalties, and requirements for corrective action. Where substances are deliberately concealed or misreported, more severe sanctions may apply. Our article on ESPR penalties and enforcement provides a detailed overview of the consequences.

Given the potential severity of enforcement actions, businesses should invest in robust data verification processes and consider third-party testing to validate supplier-provided substance data.

Practical Steps to Prepare for Substance of Concern Reporting

Preparing for ESPR substance of concern requirements is a multi-step process that requires cross-functional collaboration between procurement, quality, regulatory, and sustainability teams. Businesses should begin by mapping all substances present in their products, assessing current data quality and identifying gaps, engaging suppliers with specific data requests aligned to ESPR requirements, and establishing internal systems for managing and updating substance data.

Investing in substance tracking capabilities now will smooth the transition to mandatory reporting and reduce the risk of compliance failures when delegated acts take effect. Tools like MyProductPassport can help businesses structure and manage substance data within their Digital Product Passports, ensuring that reporting obligations are met efficiently and accurately.

The ESPR's approach to substance of concern tracking is ultimately about creating a safer, more transparent, and more circular economy. Businesses that embrace these requirements will not only avoid regulatory risk but will also contribute to a healthier product ecosystem for consumers and the environment.
