Substance Compliance Management Software

Substance compliance is not limited to checking whether a chemical appears on a restricted substances list. Businesses need to understand the substance, its concentration, where it occurs in the product structure, which regulatory requirement applies, whether a threshold is exceeded and what documentation or reporting action may be required.

For example, the EU REACH Candidate List can create obligations for substances of very high concern present in articles. ECHA states that suppliers of articles containing a Candidate List substance above 0.1% weight by weight may have communication obligations, while EU suppliers placing qualifying articles on the market may also have SCIP notification obligations.

REACH Annex XVII introduces another type of control. It contains restrictions that may limit or prohibit the manufacture, placing on the market or use of specified substances, including substances in mixtures or articles.

RoHS applies a different compliance model for electrical and electronic equipment, with substance limits defined at homogeneous-material level. The Directive's Annex II, for example, specifies maximum concentration values for regulated substances such as lead, mercury, cadmium and hexavalent chromium.

A scalable substance compliance system therefore needs to connect product composition with the particular rules, thresholds and evidence relevant to each compliance framework.

Effective substance compliance begins with reliable master data. ComplyMarket provides dedicated Substance Management capabilities designed to organize substance information centrally.

Substance profiles can contain identifiers and compliance-related attributes including:

• Substance name
• CAS number
• EC number
• Substance groups
• EPA accession number where applicable
• Hazard classes or categories
• Environmental, health and safety impact information
• REACH Annex XVII entry information
• Conditions, comments and alternative names

The platform can also connect an individual substance to legislation and sub-legislation records together with the associated threshold unit and threshold value. This provides a structured connection between the identity of a substance and the regulatory conditions used during compliance review.

Organizations can therefore maintain substance information as reusable compliance data rather than repeatedly collecting the same information for individual products or projects.

Knowing that a regulated substance exists in a database is only the beginning. Compliance teams must know where that substance appears within actual products.

ComplyMarket supports BOM structures connecting finished products, components, materials and substances. During BOM creation, substances can be assigned to their relevant parent and their concentration entered as percentage by weight.

The Substance Composition view can collect substances contained throughout the product hierarchy, including substances indirectly contained through materials and components. The available information includes substance name, CAS number, EC number and concentration data.

This provides important traceability when teams need to answer practical questions such as:

Which products contain a regulated substance? Which component introduces it? Which material contains it? What concentration has been recorded? Which suppliers are associated with the relevant item?

By maintaining these relationships in one environment, businesses can investigate substance issues without manually reconstructing the BOM every time a regulatory or customer requirement changes.

Substance regulations frequently work through lists or groups rather than isolated chemical records. ComplyMarket allows substances to be connected to substance groups and applicable legislation.

A substance group can be associated with main legislation and, where required, sub-legislation. Users can review the substances within the group together with identifiers such as CAS and EC numbers.

Individual substances can also be linked to more than one legislation, with threshold units and threshold values maintained for the relevant regulatory relationship.

This structure is particularly valuable because regulatory treatment can vary significantly between jurisdictions and legal frameworks. A substance may be restricted under one requirement, declarable above a particular threshold under another, or subject to reporting and communication obligations elsewhere.

Much of the information needed for substance compliance originates upstream. Manufacturers may depend on component suppliers, material suppliers and contract manufacturers to provide accurate declarations and composition information.

ComplyMarket supports supplier questionnaires and questionnaire packages as part of Material Compliance Management. Supplier campaigns can be reviewed after completion, responses can be approved, response progress can be monitored and answer history can be retained where questionnaires have been submitted more than once.

The documented concentration logic also addresses situations where supplier substance information interacts with internal company data. Supplier-provided concentration information can take precedence when available, newer responses can replace earlier responses, and inconsistent concentration values can result in a warning requiring review.

This creates a more controlled process for turning supplier responses into usable compliance information.

The same component or material may be purchased from multiple manufacturers, creating differences in substance composition.

ComplyMarket can calculate average, minimum and maximum substance composition values where a material or component is sourced from multiple suppliers. The platform documentation also makes an important distinction: for complex multi-sourced compositions, these calculated values are estimates, while the true composition depends on the actual components used in a production batch.

This distinction helps compliance professionals use composition calculations appropriately rather than treating estimated supply-chain scenarios as confirmed production data.

Substance information becomes more valuable when teams can turn it into actionable compliance status and reporting.

ComplyMarket's Material Compliance Management environment includes reporting capabilities for areas such as REACH SVHC and SCIP, PFAS, RoHS, material risk assessment and status reporting by substance, legislation, item and supplier.

The platform also provides supplier-focused status reporting that distinguishes between missing declarations, failed declarations, declarations requiring further review and passed declarations. This enables compliance and procurement teams to identify where supplier follow-up is required instead of reviewing every declaration manually.

In the United States, PFAS reporting under TSCA Section 8(a)(7) demonstrates why structured substance information and regulatory monitoring are increasingly important. EPA's requirements concern information such as chemical identity, uses, volumes and other PFAS-related data, while the reporting framework has also undergone timing and scope changes.

Substance compliance becomes especially difficult when companies manage thousands of products, components and materials.

ComplyMarket supports bulk BOM uploads using structured Excel templates, including products, components, materials and substances. Upload status information can be reviewed, failed records can be identified and corrected, and larger datasets can be divided into multiple upload files where necessary.

This allows organizations to build a structured compliance data foundation without relying entirely on manual item-by-item entry.

ComplyMarket's public platform information also describes centralized composition and substance management, regulatory lists, concentration tracking, multi-level BOMs and bulk data handling as connected elements of its Product Data Management environment.

A structured process can help businesses make substance compliance repeatable across products and markets:

1. Build the product structure by connecting finished products, components, materials and substances.
2. Standardize substance identification using reliable names and identifiers such as CAS and EC numbers.
3. Record concentration information at the appropriate product, component or material level.
4. Connect substances to legislation and maintain the relevant thresholds, groups and regulatory conditions.
5. Collect missing information from suppliers through structured questionnaires and declaration workflows.
6. Review compliance status and warnings by substance, item, supplier and legislation.
7. Generate the required compliance outputs and update records when products, suppliers, substance information or regulatory requirements change.

The result is a continuous compliance process rather than a one-time restricted-substance check.

Centralized substance compliance management can help manufacturers and supply-chain organizations reduce fragmented data, improve visibility and respond faster to regulatory or customer enquiries.

Compliance teams gain a clearer relationship between substances and applicable requirements. Procurement teams can identify suppliers with missing or problematic declarations. Engineering teams can understand where restricted substances occur within the BOM. Quality teams can access supporting documentation and status information. Management can obtain a consolidated view of compliance gaps across the product portfolio.

Most importantly, structured substance data becomes reusable. The same product and supplier information can support multiple compliance workflows rather than being recreated for every regulatory request.

ComplyMarket can support businesses in establishing a structured, scalable approach to substance compliance across complex products and supply chains.

The platform brings together BOM management, substance inventories, substance groups, regulatory relationships, concentration information, supplier questionnaires and compliance reporting within one connected environment. Substance records can be traced back to the products, components and materials in which they occur, while regulatory thresholds and legislation can be linked directly to the relevant substances.

Supplier workflows help businesses collect missing information and review declaration status, while reporting capabilities provide visibility by substance, legislation, item and supplier. Dedicated reporting areas also support important material-compliance topics including REACH SVHC and SCIP, RoHS and PFAS.

For organizations managing large product portfolios, bulk BOM functionality can further support efficient onboarding of product, component, material and substance information.

By combining product structure, regulatory information and supplier evidence, ComplyMarket Substance Compliance Management Software helps companies create a more traceable and controlled substance compliance process—from data collection and composition analysis to regulatory review and reporting.
