Introduction to REACH and DPP Integration

The Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation has been the cornerstone of EU chemical safety policy since 2007. It requires manufacturers and importers to identify and manage the risks associated with chemical substances placed on the European market. Now, with the introduction of the Ecodesign for Sustainable Products Regulation (ESPR) and its Digital Product Passport (DPP) requirements, a new chapter in chemical compliance is opening.

The ESPR explicitly requires that Digital Product Passports include information about substances of concern present in products. This creates a direct link between REACH compliance data and DPP obligations, offering both opportunities for streamlined reporting and challenges for businesses that must now present chemical data in new formats and through new channels. Understanding how these two regulatory frameworks interact is essential for any manufacturer or importer operating in the EU market.

This article explores the intersection of REACH and DPP requirements, examining what chemical data must be included in Digital Product Passports, how existing REACH compliance processes can be leveraged, and what practical steps businesses should take to integrate their chemical compliance workflows with DPP systems.

Understanding Substances of Concern Under the ESPR

The ESPR introduces the concept of "substances of concern" as a central element of Digital Product Passport data requirements. This concept is broader than the REACH Candidate List of Substances of Very High Concern (SVHCs), encompassing any chemical substance that may have a negative impact on the sustainability of products, including their recyclability, durability, or reparability.

Substances of concern under the ESPR framework include:

• Substances on the REACH Candidate List of Substances of Very High Concern (SVHCs), currently numbering around 250 entries
• Substances restricted under REACH Annex XVII, which sets conditions for the manufacture, placing on the market, and use of certain dangerous substances
• Substances classified as carcinogenic, mutagenic, or toxic for reproduction (CMR) under the CLP Regulation
• Substances that negatively impact the recycling of materials in which they are present
• Substances identified through delegated acts as problematic for specific product categories due to their environmental or health impacts

This expanded scope means that businesses cannot simply transpose their existing REACH compliance data into their DPPs without additional analysis. They must assess whether their products contain any substances that fall within the broader ESPR definition, even if those substances are not currently subject to REACH authorisation or restriction requirements.

Chemical Data Requirements in Digital Product Passports

The ESPR sets out specific requirements for how chemical substance information must be presented in Digital Product Passports. These requirements go beyond simple declarations of SVHC presence, demanding detailed, machine-readable data that enables downstream users, recyclers, and consumers to make informed decisions about product handling and end-of-life management.

For each substance of concern present in a product, the DPP must typically include the substance name and its unique identifier (CAS or EC number), the concentration range in which the substance is present, the specific component or material within the product that contains the substance, and information about safe handling and disposal requirements. The exact data fields will be specified in product-category-specific delegated acts, but the regulation establishes the general principle that chemical transparency must be a core feature of every DPP.

This level of detail represents a significant step up from current REACH Article 33 obligations, which require suppliers to communicate information about SVHCs present above 0.1% weight by weight in articles. The DPP framework demands not just notification but structured, standardised data that can be automatically processed and analysed across the supply chain.

Leveraging Existing REACH Compliance Processes

The good news for businesses with mature REACH compliance programmes is that much of the data and many of the processes needed for DPP chemical compliance are already in place. The challenge lies in restructuring and extending this data to meet DPP format and scope requirements.

Existing REACH compliance assets that can be leveraged for DPP integration include:

• SVHC declarations collected from suppliers under REACH Article 33, which provide a starting point for identifying substances of concern in products
• Safety Data Sheets (SDS) maintained under REACH Article 31, which contain detailed information about substance hazards, composition, and safe handling
• SCIP database notifications submitted to the European Chemicals Agency (ECHA), which already require structured data about articles containing SVHCs
• Chemical inventory databases maintained internally for REACH registration and compliance tracking purposes
• Supply chain communication protocols established for REACH compliance, which can be extended to request additional substance data needed for DPPs

Businesses that have invested in the SCIP database notification process are particularly well-positioned, as the data structure required for SCIP notifications shares significant overlap with DPP chemical data requirements. In many cases, extending SCIP workflows to cover the broader DPP scope will be more efficient than building DPP chemical compliance processes from scratch.

Supply Chain Data Collection Challenges

One of the most significant practical challenges in integrating REACH data with DPP requirements is collecting comprehensive substance information from complex, multi-tier supply chains. Whilst REACH Article 33 establishes a legal obligation for suppliers to communicate SVHC information, compliance with this obligation remains inconsistent, and the broader scope of DPP requirements will demand even more extensive data collection efforts.

Common supply chain challenges include incomplete or inaccurate SVHC declarations from upstream suppliers, limited visibility into the chemical composition of complex components or assemblies sourced from third countries, difficulties in obtaining substance-level data from suppliers who consider their formulations to be trade secrets, and the practical challenge of managing chemical data across product portfolios that may contain thousands of individual components.

To address these challenges, businesses should consider implementing full material disclosure (FMD) requirements in their supplier contracts, investing in supply chain management platforms that can collect, validate, and aggregate chemical data from multiple tiers, engaging with industry initiatives that provide standardised substance data exchange formats, and building relationships with key suppliers based on shared commitment to transparency and compliance.

The textile sector provides a useful example of how chemical compliance integrates with broader DPP requirements. Our guide on Digital Product Passports for textiles covers the specific chemical data challenges and solutions relevant to this important product category.

Technical Integration Approaches

From a technical perspective, integrating REACH chemical data with DPP systems requires careful attention to data architecture, interoperability standards, and workflow design. The goal is to create a seamless flow of chemical data from raw material suppliers through to the final DPP, minimising manual data entry and the associated risk of errors.

Several technical approaches are emerging as best practices:

• Adopting standardised chemical data exchange formats such as IPC-1752A for material declarations, which can serve as an input layer for DPP systems
• Implementing middleware solutions that map existing chemical database schemas to DPP data models, enabling automated data transfer without requiring wholesale changes to legacy systems
• Using application programming interfaces (APIs) to connect enterprise resource planning (ERP) systems, product lifecycle management (PLM) systems, and DPP platforms, creating an integrated data pipeline
• Establishing data validation rules that automatically check incoming substance data against the REACH Candidate List, restriction list, and any additional substances of concern identified in ESPR delegated acts
• Building audit trail capabilities that track the provenance of chemical data throughout the supply chain, supporting regulatory inspections and customer due diligence requests

The investment in technical integration infrastructure will pay dividends beyond DPP compliance. A well-designed chemical data management system supports faster product development, more efficient regulatory reporting, and improved risk management across the product portfolio.

Regulatory Convergence and Future Developments

The integration of REACH and DPP requirements is part of a broader trend towards regulatory convergence in the EU's chemicals and sustainability policy landscape. The European Commission's Chemicals Strategy for Sustainability, published in 2020, explicitly called for better alignment between chemicals regulation and circular economy objectives, and the ESPR's substance-of-concern provisions are a direct result of this strategic direction.

Looking ahead, several developments are likely to deepen the connection between chemical compliance and Digital Product Passports. The ongoing revision of REACH is expected to introduce new provisions for chemicals in products that align more closely with DPP data requirements. The Commission is also exploring how DPP data can be used to improve chemical risk assessment by providing better information about actual substance concentrations in products on the market.

Furthermore, the development of the circular economy framework is creating additional drivers for chemical transparency. Recyclers and waste managers need to know what substances are present in products to ensure safe and effective end-of-life processing. The DPP, with its comprehensive chemical data, has the potential to transform waste management by providing the information needed to sort, process, and recycle materials safely.

Practical Steps for Businesses

Businesses seeking to integrate their REACH compliance processes with DPP requirements should take a phased approach. Begin by conducting an audit of existing chemical data assets, identifying gaps between current REACH compliance data and the broader substance-of-concern information required by the ESPR. Next, assess supply chain readiness by surveying key suppliers about their ability to provide the additional data needed for DPPs. Then, evaluate technology solutions that can bridge the gap between existing chemical data management systems and emerging DPP platforms.

The organisations that move early on REACH-DPP integration will find themselves with a significant competitive advantage. Not only will they be better prepared for mandatory DPP requirements as delegated acts come into force, but they will also be able to demonstrate the kind of chemical transparency that is increasingly demanded by consumers, retailers, and institutional buyers. In a market where sustainability credentials are becoming a key differentiator, the ability to provide comprehensive, verified chemical data through a Digital Product Passport is a powerful commercial asset.

10-Step Action Plan for Chemical Producers

1. Inventory your chemical portfolio. List every product placed on the EU market with REACH registration status, CLP classification, and current data quality.
2. Audit SCIP submissions. Substances of very high concern in articles must be submitted to ECHA SCIP. The DPP draws on this data.
3. Document hazard classification. CLP hazard pictograms, signal words, hazard statements all feed the DPP hazard fields.
4. Update safety data sheets to the latest format. SDSs feed the DPP. Keep them current with the latest CLP and REACH updates.
5. Engage downstream users. Article-level DPPs will pull substance data from chemical suppliers. Anticipate the requests.
6. Plan for authorisation deadlines. Annex XIV substances require REACH authorisation. The DPP records authorisation status.
7. Map SVHC list updates to your portfolio. ECHA updates the SVHC list twice yearly. Each update is a portfolio re-assessment.
8. Choose a DPP hosting model. Chemical producers typically have substantial existing regulatory infrastructure. Integration with that infrastructure is the priority.
9. Pilot on one product line. Choose a product with clean SCIP and CLP data, build the full DPP, test data flow to article-level customers.
10. Update commercial contracts. Customer contracts should reference DPP data provision as part of standard supply terms.

Frequently Asked Questions

When does the chemicals DPP become mandatory?

Chemicals are not a product group in the ESPR working plan 2025-2030, but chemical data feeds the article-level DPPs of every sector that is, and detergents get a passport under their own Regulation (EU) 2026/405 from 23 September 2029. SVHC disclosure under REACH and SCIP is already in force.

What data must a chemicals DPP contain?

CLP hazard classification, REACH registration status, SVHC content, authorisation status, recycled and bio-based content, and end-of-life guidance.

How does the DPP relate to REACH?

REACH provides the substance-level data foundation. The DPP draws on REACH registrations, restrictions, and authorisations to populate substance-of-concern fields.

How does the DPP relate to SCIP?

SCIP collects SVHC data for articles. The DPP draws on SCIP submissions for substance-of-concern disclosure in article-level DPPs.

What about CLP labelling?

CLP hazard pictograms and statements remain mandatory on the physical product. The DPP carries the underlying classification data plus richer detail.

Do non-EU chemical producers need to comply?

Yes. Chemicals placed on the EU market require DPPs regardless of manufacturing origin. Only Representatives carry responsibility for non-EU producers.

What about bulk chemical deliveries?

Tankered chemicals link DPP data to delivery documentation rather than individual packaging.

How does the DPP support downstream users?

Article manufacturers using your chemicals need substance data for their own DPPs. The DPP standardises the data exchange.
