Does my Responsible Person need my Bill of Materials?

A GPSR responsible person does not automatically need your full Bill of Materials (BOM), but it may be required when necessary to demonstrate product safety or compliance with other applicable EU rules. Under the General Product Safety Regulation (EU) 2023/988 (GPSR), the key requirement is that relevant technical documentation can be made available to authorities on request. This article explains what a BOM is, when it matters, and how to share it safely.

What is a Bill of Materials, and how is it used in product compliance?

A Bill of Materials (BOM) is a structured list of the parts, materials, and subassemblies that make up a product, often including supplier references and specifications. In compliance work, a BOM supports traceability and helps assess whether restricted substances or safety-critical components are present. It is not the same as technical documentation, and it does not replace testing or risk analysis.

To avoid confusion, these documents serve different purposes:

BOM: what the product is made of, at the component and material level.
Technical documentation: the compiled evidence showing how product safety is ensured (description, safety-relevant characteristics, applied standards, and the manufacturer’s risk analysis, plus supporting evidence where appropriate).
Test reports: laboratory or internal test results against specific methods or standards.
Risk assessment: identification of hazards, foreseeable use and misuse, and risk controls.
Declarations: formal statements used under specific legislation (for example, a Declaration of Conformity under CE-marking laws, when applicable), not a universal GPSR requirement.

Does the GPSR responsible person need the Bill of Materials?

Under the GPSR, the responsible person is an EU-established economic operator that must be able to cooperate with market surveillance authorities and make relevant technical documentation available on request. A BOM is only needed if it forms part of the documentation required to demonstrate safety, or if it is necessary to answer an authority’s question about composition, traceability, or restricted substances.

In practice, a responsible person often verifies that technical documentation exists and is complete enough to be provided promptly when requested. If a market surveillance authority asks what materials are in a product, or whether a restricted substance could be present, a BOM—or a controlled extract of it—can be the fastest way to respond accurately.

Also note the interaction with the Market Surveillance Regulation (EU) 2019/1020 (MSR): if the responsible person has reason to believe a product presents a risk, it must inform the manufacturer (Article 4 MSR). Having the right composition information can be important for that internal escalation.

When a Bill of Materials is essential versus optional

A BOM is essential when product composition drives legal compliance or safety conclusions, and optional when safety can be demonstrated without detailed component disclosure. The deciding factor is whether material-level detail is needed to show compliance with applicable rules, manage traceability, or answer foreseeable authority questions.

Situation	BOM typically	Why it matters
REACH restrictions and SVHC screening	Essential	Substance presence depends on materials, additives, and supplier inputs.
RoHS for electrical and electronic equipment	Essential	Homogeneous material restrictions often require component-level declarations and traceability.
Packaging compliance (materials, heavy metals, composition controls)	Often needed	Packaging materials can trigger separate obligations and evidence requests.
Textiles and fiber composition labeling	Often needed	Fiber content must be supported by reliable composition information.
Food-contact materials (when applicable)	Essential	Compliance depends on material formulation and supplier declarations.
Simple, low-risk products with stable materials and clear test evidence	Optional	Risk assessment, labeling, and test reports may be sufficient.

How to share a Bill of Materials with a responsible person safely

You can share BOM information safely by providing only what is needed for regulatory cooperation, while protecting confidential design and sourcing details. The responsible person usually needs enough information to respond to market surveillance requests, confirm traceability, and verify that safety documentation matches the product placed on the market.

Use a confidentiality agreement before sharing any BOM or supplier-identifying data.
Share a compliance BOM (materials, substance declarations, safety-critical parts) instead of a full manufacturing BOM.
Redact supplier names where not needed, but keep unique component identifiers for traceability.
Use component-level declarations (for example, RoHS and REACH statements) linked to BOM line items.
Provide controlled access (a read-only portal, expiring links) rather than emailing editable spreadsheets.
Apply version control so the BOM matches the exact model, variant, and production change level.

Minimum information that is often sufficient includes product model identifiers, a component list for safety-relevant parts, material declarations for restricted substances, and a clear mapping between the BOM version and the product placed on the EU market.

How EARP helps with responsible person BOM and documentation handling

With [COMPANY], we help you decide whether a BOM is needed for your product and, if it is, how to provide the right level of detail without oversharing. Our work is structured to support fast, accurate responses to market surveillance requests and consistent documentation control.

We review which documentation is relevant under the GPSR and other applicable EU rules for your product type.
We set up a practical document set, including BOM extracts and supplier declarations when composition matters.
We maintain controlled storage and retrieval processes so documentation can be made available to authorities on request.
We help align identifiers across labels, listings, and files to reduce avoidable compliance friction.
