If you manufacture, import, or place electrical and electronic equipment (EEE) on the EU market, RoHS compliance is not simply a matter of obtaining a supplier certificate.
You need to be able to demonstrate that the materials, components and products you place on the market meet the applicable substance restrictions — and that you have the evidence to support that conclusion.
The EU Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU, as amended, restricts the use of specified hazardous substances in electrical and electronic equipment. The Directive is intended to protect human health and the environment and applies requirements to economic operators across the EEE supply chain.
For electronics manufacturers, that creates a practical compliance chain:
Supplier data → materials → components → BOM → finished product → technical documentation → conformity evidence
The challenge is that the information required to establish compliance often sits across engineering, procurement, suppliers, quality and regulatory teams.
This guide will help you understand how EU RoHS compliance works and, more importantly, how manufacturers can operationalize it across their product and supply chains.
What Is EU RoHS?
RoHS stands for Restriction of Hazardous Substances.
The EU RoHS Directive restricts the use of specified hazardous substances in electrical and electronic equipment placed on the EU market. Directive 2011/65/EU is the current foundational legislation, with subsequent amendments adding substances and modifying exemptions and other requirements.
RoHS is therefore not a voluntary environmental certification.
It is a product compliance requirement.
For manufacturers, the central question is:
Can we demonstrate that every applicable material and component in our EEE product complies with the RoHS substance restrictions or is legitimately covered by an applicable exemption?
That distinction matters.
A supplier saying:
"RoHS compliant"
is useful evidence, but it may not be sufficient by itself for every product and technical-documentation scenario.
A robust compliance process needs to connect the supplier's declaration to the actual component, material, product and applicable evidence.
Who Needs to Comply With EU RoHS?
RoHS applies to electrical and electronic equipment within the scope of the Directive.
The Directive places obligations on different economic operators, including manufacturers, importers and distributors. Manufacturers have a responsibility to ensure that EEE they place on the market has been designed and manufactured in accordance with the Directive.
For manufacturers, this means RoHS needs to be considered during:
- product design
- component selection
- material sourcing
- supplier qualification
- BOM management
- engineering changes
- product conformity assessment
- technical documentation
- market release
- ongoing compliance monitoring
This is why RoHS should not be treated as a yearly declaration exercise.
It needs to be connected to the product lifecycle.
Which Products Are Covered by RoHS?
The RoHS Directive applies to EEE falling within the categories set out in Annex I, subject to the Directive's scope provisions and exclusions.
Depending on the product and applicable category, manufacturers may need to evaluate products such as:
- consumer electronics
- computers and IT equipment
- telecommunications equipment
- electrical appliances
- lighting equipment
- electrical and electronic tools
- toys and leisure equipment
- medical devices
- monitoring and control instruments
- automatic dispensers
- other EEE covered by the Directive
Important: Product classification should be assessed against the actual Directive and applicable exclusions rather than assuming that every electronic product is automatically in scope.
For a manufacturer, the first compliance question should therefore be:
Is my product within the scope of EU RoHS?
If yes, the next questions become:
- Which substance restrictions apply?
- Which components/materials contain restricted substances?
- Are any uses covered by an exemption?
- What evidence supports the assessment?
- Can the technical documentation demonstrate conformity?
What Substances Are Restricted Under EU RoHS?
The current RoHS framework restricts 10 substances.
Restricted substance | Maximum concentration in homogeneous material* |
|---|---|
Lead (Pb) | 0.1% |
Mercury (Hg) | 0.1% |
Cadmium (Cd) | 0.01% |
Hexavalent chromium (Cr VI) | 0.1% |
Polybrominated biphenyls (PBB) | 0.1% |
Polybrominated diphenyl ethers (PBDE) | 0.1% |
Bis(2-ethylhexyl) phthalate (DEHP) | 0.1% |
Butyl benzyl phthalate (BBP) | 0.1% |
Dibutyl phthalate (DBP) | 0.1% |
Diisobutyl phthalate (DIBP) | 0.1% |
Note - The limits are expressed at the homogeneous material level, and the applicable legal requirements should always be checked against the current Directive and amendments. The Commission/EUR-Lex materials identify these 10 substances and the Annex II framework.
Why the homogeneous-material concept matters
RoHS thresholds are not simply applied to the entire finished product.
A product can contain thousands of individual materials and components.
For example, an electronics assembly might contain:
- PCB laminate
- solder
- connectors
- cable insulation
- coatings
- plastics
- metal alloys
- displays
- batteries or other separately regulated elements
- mechanical components
The compliance assessment therefore needs sufficient material-level information to determine whether restricted substances exceed the applicable limits.
This is one reason BOM-level and supplier-level data are so important.
How Do Manufacturers Assess RoHS Compliance?
A practical electronics RoHS workflow looks like this:
1. Identify products in scope
Determine which products fall within the RoHS Directive.
2. Structure the BOM
Break the product down into components and materials that can be assessed.
3. Identify restricted-substance exposure
Determine whether components or materials contain any of the restricted substances.
4. Collect supplier evidence
Request relevant declarations, material disclosures, specifications, test evidence or other supporting information.
5. Evaluate exemptions
Where a restricted substance is present, determine whether the particular application qualifies for an applicable RoHS exemption.
6. Document the assessment
Maintain evidence supporting the conformity assessment.
7. Monitor changes
Reassess products when suppliers, components, materials, exemptions or regulatory requirements change.
This creates a much stronger compliance model than simply maintaining a folder of supplier PDFs.
What Is a RoHS Supplier Declaration?
A RoHS supplier declaration is a statement from a supplier concerning compliance of a component, material or product with applicable RoHS requirements.
Supplier declarations can be valuable evidence, but manufacturers should understand what the declaration actually covers.
A supplier declaration may refer to:
- a specific component
- a component family
- a material
- a product range
- a specific revision
- a date or validity period
- particular RoHS exemptions
The manufacturer's responsibility is to ensure the evidence is relevant to the product being assessed.
A stronger supplier-data process asks:
- Which part number does this declaration cover?
- Which revision?
- Which materials?
- Which restricted substances?
- Are any exemptions claimed?
- Which exemption numbers?
- What evidence supports the claim?
- When was the declaration issued?
- Has the supplier changed the material or manufacturing process?
- Does the declaration still reflect the current component?
This is where supplier-data management becomes a core part of RoHS compliance.
Why BOM-Level RoHS Compliance Matters
For electronics manufacturers, the BOM is effectively the bridge between engineering and regulatory compliance.
Consider a product containing:
1,500 components
A single supplier declaration covering the finished assembly does not necessarily provide the same level of visibility as a structured assessment of the underlying components and materials.
A manufacturer needs to understand:
Product → BOM → Component → Material → Substance → Evidence
That structure allows compliance teams to answer questions such as:
Which products contain components relying on a particular RoHS exemption?
or:
Which products are affected if a supplier changes the material used in a connector?
or:
Which components have missing or outdated compliance evidence?
This is why the RoHS compliance process should be connected to product and supplier data rather than maintained separately from engineering systems.
What Are RoHS Exemptions?
RoHS exemptions allow specified applications to use restricted substances where the legal conditions for the exemption are met.
They are not blanket permissions to use a restricted substance.
The European Commission explains that exemptions are granted under specific conditions, are limited in time, and are periodically reassessed based on factors including availability and reliability of substitutes, environmental and health impacts, socioeconomic effects and potential impacts on innovation.
Exemptions are listed primarily in:
- Annex III
- Annex IV
of the RoHS framework.
This creates an important manufacturer responsibility:
Do not simply record "RoHS compliant — exemption applies."
Instead, record:
Restricted substance → specific application → applicable exemption → evidence → expiry/review status
That distinction becomes especially important as exemptions change.
RoHS Exemption Expiry Must Be Monitored
RoHS exemptions are not permanent.
The European Commission states that exemption renewal applications generally need to be submitted no later than 18 months before expiry. The Commission also notes that exemption decisions can take approximately 18–24 months from the application date.
For manufacturers, that means an exemption register should not simply answer:
"Is exemption 7(a) applicable?"
It should also answer:
- Which components use it?
- Which products are affected?
- Which supplier supplied the evidence?
- What is the current expiry date?
- Is a renewal under consideration?
- What happens if the exemption expires?
- Is an alternative material/component available?
- How long would qualification take?
This is one of the areas where automated exemption monitoring can provide significant operational value.

What Is IEC 63000 and How Does It Relate to RoHS?
EN IEC 63000:2018 provides a framework for technical documentation used to demonstrate compliance with RoHS substance restrictions.
It is particularly relevant when manufacturers need to structure and maintain the evidence supporting their RoHS conformity assessment.
For the detailed documentation workflow, see:
EN IEC 63000:2018 RoHS Technical Documentation.
The key point for manufacturers is that RoHS compliance is not only about the conclusion:
"This product is compliant."
It is about being able to support that conclusion with appropriate technical evidence.
A useful evidence chain is:
Supplier information → component/material information → assessment → technical documentation → conformity declaration
What Documentation Should Manufacturers Maintain?
The exact documentation required depends on the product and applicable conformity-assessment requirements, but a manufacturer's RoHS compliance file may include:
- product identification
- product description
- BOM/component information
- material information
- supplier declarations
- material declarations
- relevant test reports
- exemption information
- exemption justification
- technical assessment records
- conformity documentation
- change-management records
- supporting technical evidence
The objective is to maintain enough evidence to demonstrate that the product meets the applicable RoHS requirements.
The manufacturer should therefore be able to trace:
Why did we conclude that this product is RoHS compliant?
and:
What evidence supports that conclusion?
How Does RoHS Relate to CE Marking?
RoHS compliance is part of the EU product-conformity framework for EEE covered by the Directive.
However, CE marking is not a standalone RoHS certificate.
A product may be subject to several EU product requirements at the same time.
Depending on the product, these can include requirements associated with:
- RoHS
- EMC
- Low Voltage
- Radio Equipment
- other applicable EU legislation
The manufacturer must identify and comply with the legislation applicable to the product before affixing CE marking.

RoHS vs REACH: Are They the Same?
No.
RoHS and REACH are separate EU regulatory frameworks.
RoHS
Focuses specifically on restrictions of certain hazardous substances in electrical and electronic equipment.
REACH
Is the broader EU chemicals framework covering the registration, evaluation, authorisation and restriction of chemical substances.
For electronics manufacturers, both can matter.
A component may therefore need to be assessed against:
RoHS requirements + REACH requirements + other applicable product/material regulations

How Manufacturers Should Operationalize RoHS Compliance
A mature RoHS programme should connect five data layers:
1. Regulatory layer
Track:
- restricted substances
- thresholds
- exemptions
- regulatory amendments
- exemption expiry/review
2. Supplier layer
Track:
- supplier declarations
- material declarations
- component evidence
- declaration dates
- supplier changes
- missing evidence
3. Product layer
Track:
- products
- BOMs
- components
- materials
- product revisions
4. Evidence layer
Track:
- technical documentation
- test reports
- supplier evidence
- exemption justification
- conformity records
5. Risk layer
Identify:
- missing declarations
- expired evidence
- exemption dependencies
- affected products
- high-risk suppliers
- components requiring reassessment
This turns RoHS from a document-collection exercise into a proactive product compliance process.
Common RoHS Compliance Mistakes
1. Treating "RoHS compliant" as sufficient evidence
A generic declaration may not provide the product/component-level information required for a defensible assessment.
2. Ignoring supplier changes
A component can change even when its part number appears unchanged.
3. Tracking exemptions manually
Exemptions have specific scopes and time limits. The Commission confirms that they are periodically reassessed.
4. Assessing only the finished product
A manufacturer needs visibility into the materials and components that make up the product.
5. Keeping technical documentation disconnected from the BOM
If engineering changes a component, compliance evidence can become stale.
6. Treating RoHS as a one-time certification
RoHS compliance needs to be maintained as products, suppliers, materials and regulatory requirements change.
A Practical EU RoHS Compliance Checklist for Electronics Manufacturers
Before placing an EEE product on the EU market, ask:
Product scope
Restricted substances
Supplier data
Exemptions
Technical documentation
Ongoing monitoring
How Regilient Helps Manufacturers Manage RoHS Compliance
RoHS becomes difficult at scale because the data is distributed.
A manufacturer may have:
- thousands of components
- hundreds of suppliers
- multiple product revisions
- different supplier declarations
- changing exemptions
- different evidence formats
- multiple regulatory requirements
Regilient is designed to bring these compliance workflows together.
The platform can support manufacturers with:
BOM and component screening
Connect product and component information to regulatory requirements.
Supplier declaration collection
Automate supplier outreach and follow-ups to collect required compliance information.
Supplier evidence validation
Organize and assess supplier declarations and material information.
Exemption management
Track exemptions and their relevant dates so teams can identify products that may be affected by regulatory changes.
Compliance reporting
Generate structured compliance outputs and maintain evidence for audit and regulatory needs.
Continuous monitoring
Connect regulatory changes to affected products, components and supplier evidence.
The goal is simple:
Know what is in your products, know what evidence supports compliance, and know what changes could put that compliance at risk.
