RoHS Homogeneous Material Definition and Limits

Evidence to keep for the homogeneous-material decision

The useful record is not a generic RoHS certificate. It is a material-level trail that shows how the product was split, which Annex II threshold was applied, what declaration or test evidence supports the conclusion, and which exemptions or carve-outs were considered where relevant.

EN IEC 63000:2018 is the harmonised technical-documentation standard referenced for assessing materials, components, and electrical and electronic equipment under Directive 2011/65/EU. Use it as the organizing frame for supplier declarations, test reports, risk assessment, and conformity records.

  • Keep a material breakdown tied to the product version, supplier, part number, and revision.
  • Record the applicable Annex II threshold for each material rather than a single product-level pass/fail statement.
  • Keep supplier declarations, IEC 62321 test reports where needed, exemption rationale, change-control records, and EN IEC 63000 technical documentation together with the EU declaration of conformity.

RoHS Homogeneous Material Definition and Limits

Common mistakes with homogeneous materials

The most common mistake is treating a supplier's broad product declaration as proof for every material in the part. That declaration may be useful, but it should still map to the homogeneous materials and Annex II thresholds that RoHS actually uses.

Another mistake is testing a mixed sample and treating the result as decisive when one high-risk separable material could be diluted by lower-risk material mass. If the legal question is material-level, the evidence should stay material-level.

  • Do not average lead in a solder joint across a whole circuit board or finished appliance.
  • Do not treat a plated metal part as a single material decision without considering whether the plating or coating needs separate evidence.
  • Do not reuse old material declarations after supplier, formulation, plating, coating, resin, recycled-content, or process changes without checking whether the RoHS material evidence still matches.

RoHS importer checks for imported EEE before EU market placement

What must importers check before placing EEE on the EU market under RoHS?

Article 9 of Directive 2011/65/EU makes the importer a gatekeeper for imported EEE. The importer must place only EEE that complies with RoHS on the Union market, and must check the manufacturer's conformity work before the first EU market placement.

The practical pre-placement check is not just a supplier questionnaire. It should verify the manufacturer's conformity assessment, technical documentation, CE marking, required documents, manufacturer identification and address details, importer identification and contact address, and any facts that could show the EEE is not in conformity with Article 4 substance restrictions.

  • Confirm the product is EEE in scope and is being placed on the EU market by the importer.
  • Check that the manufacturer carried out the appropriate conformity assessment and drew up RoHS technical documentation.
  • Check that the finished EEE bears the CE marking and is accompanied by the required documents.
  • Check that manufacturer identification and address information are present, and add the importer name, registered trade name or trade mark, and contact address on the EEE or, where that is not possible, on the packaging or accompanying document.
  • If there is reason to believe the EEE is not RoHS-compliant, do not place it on the market until it has been brought into conformity; inform the manufacturer and the market surveillance authorities.

RoHS importer checks for imported EEE before EU market placement

Which evidence should an importer keep for imported EEE?

The importer must keep a copy of the EU declaration of conformity for 10 years after placing the EEE on the market and must ensure the technical documentation can be made available to market surveillance authorities on request. That makes the import file an evidence index as much as a purchasing record.

A useful importer file links the exact product identity to the EU declaration, technical documentation access route, CE marking check, manufacturer and importer traceability markings, supplier material evidence, and any exemption or change-control assumptions used to support the RoHS conclusion.

  • Store the EU declaration of conformity for the model or product family actually imported, and verify it references Directive 2011/65/EU where RoHS applies.
  • Record where the RoHS technical documentation can be obtained quickly if an authority asks for it; EN IEC 63000:2018 is the harmonised technical-documentation standard referenced in Commission Implementing Decision (EU) 2020/659.
  • Keep evidence that the CE mark was present before market placement and that required accompanying documents were present in the needed language context.
  • Keep a register of non-compliant EEE and recalls, and document corrective action, withdrawal, recall, and authority notifications where relevant.
  • Tie supplier declarations, material declarations, test reports, and exemption claims to the exact EEE, component, material, model, batch, or revision they support.

RoHS importer checks for imported EEE before EU market placement

What should stop the importer from placing the EEE on the market?

Article 9 is explicit: if an importer considers or has reason to believe that EEE is not in conformity with Article 4, the importer must not place it on the market until it has been brought into conformity. The importer must also inform the manufacturer and market surveillance authorities.

Use that rule as an escalation trigger. A missing or mismatched EU declaration, missing CE marking, inaccessible technical documentation, unexplained supplier evidence gap, unsupported exemption claim, product change, or credible restricted-substance concern should pause placement until the evidence is corrected.

  • Escalate mismatches between the DoC, product label, model number, batch, shipment documents, or supplier evidence.
  • Escalate missing importer or manufacturer traceability information before goods are released to the EU market.
  • Escalate any indication that a homogeneous material may exceed a RoHS restriction or that an exemption claim no longer fits the application.
  • Document the final outcome as placed, corrected before placement, withdrawn, recalled, or blocked from market placement.

RoHS importer checks for imported EEE before EU market placement

How should the importer turn the check into a repeatable workflow?

Treat imported EEE review as a release gate tied to the exact product being placed on the EU market. The decision should be readable by procurement, logistics, quality, legal, and product teams without relying on undocumented supplier conversations.

The strongest record is short but specific: what product was imported, who the manufacturer and importer are, what DoC and technical-file evidence was checked, what supplier evidence supports substance compliance, what issues were found, and who approved release or blocked placement.

  • Create one importer review record per product family, model, or shipment scope where the evidence is the same.
  • Map each imported EEE record to the DoC, technical-documentation access path, CE marking check, traceability marking check, supplier evidence, and exemption assumptions.
  • Assign owners for supplier follow-up, technical-file retrieval, nonconformity investigation, authority response, and recall-register updates.
  • Reopen the record after design changes, supplier changes, material changes, new test results, exemption changes, or authority requests.

What do the 0.1% and 0.01% substance limits mean under EU RoHS?

What do the 0.1% and 0.01% substance limits mean under EU RoHS?

Article 4 of Directive 2011/65/EU points to Annex II for the maximum concentration values tolerated by weight in homogeneous materials. That means the threshold is checked against each separable material, coating, solder, plastic, alloy, wire, or other homogeneous material, not against the finished product as a whole.

The practical split is simple but easy to misapply: cadmium has the tighter 0.01% limit; the other Annex II substances are listed at 0.1%. The four phthalates added by Delegated Directive (EU) 2015/863, DEHP, BBP, DBP, and DIBP, also sit at 0.1% in Annex II.

  • Use 0.1% by weight for lead, mercury, hexavalent chromium, PBB, PBDE, DEHP, BBP, DBP, and DIBP.
  • Use 0.01% by weight for cadmium.
  • Apply the value to each homogeneous material separately; do not dilute a restricted substance by averaging it across an assembly, component, or finished EEE.
  • If an Annex III or Annex IV exemption is used, record the exact exemption entry, product category, substance, material, and validity condition that makes the higher concentration acceptable.

What do the 0.1% and 0.01% substance limits mean under EU RoHS?

What evidence should be kept for RoHS 0.1% and 0.01% limits?

Evidence should let a reviewer trace the conclusion from the finished EEE down to the homogeneous materials that matter for Annex II. A supplier statement that only says "RoHS compliant" is weak if it does not identify covered parts, materials, substances, exemptions, or the basis for the declaration.

The technical file should connect the BOM, homogeneous-material list, material declarations, substance risk assessment, selected test reports, exemption register, EU declaration of conformity, and change-control history. Manufacturers must keep the technical documentation and EU declaration of conformity for 10 years after the EEE has been placed on the market.

  • Map each relevant homogeneous material to the applicable Annex II substance and limit: 0.01% for cadmium or 0.1% for the other listed substances.
  • Keep supplier declarations specific to the part, material, revision, and restricted substances they cover.
  • When testing is used, retain the sample description, preparation logic, test method, lab report, and the material-level result being compared with the Annex II threshold.
  • For exemptions, retain the Annex III or Annex IV entry, applicability category, expiry or renewal status, and the product/material facts that support use of the exemption.
  • Recheck the record after material changes, supplier changes, product redesign, exemption changes, or a change to the harmonised standard used for the technical documentation.

What do the 0.1% and 0.01% substance limits mean under EU RoHS?

How to apply the RoHS 0.1% and 0.01% limits

Use the limits as a material-level screening question before release, supplier approval, design change, or exemption review. The output should be a clear pass, exemption-supported, or nonconforming-material decision for each material-substance pair.

  • Identify the EEE, category, part number, supplier, revision, and date of placing on the market.
  • Break the relevant assemblies into homogeneous materials, including plastics, metals, coatings, solder, insulation, cables, and phthalate-relevant polymer parts.
  • For each homogeneous material, mark whether cadmium, lead, mercury, hexavalent chromium, PBB, PBDE, DEHP, BBP, DBP, or DIBP is relevant.
  • Compare cadmium results or declarations to 0.01% by weight and all other Annex II substance results or declarations to 0.1% by weight.
  • If a value exceeds the Annex II limit, stop treating the material as compliant unless an exact Annex III or Annex IV exemption covers that use.
  • Store the conclusion in the RoHS technical documentation package used to support the CE marking and EU declaration of conformity.

What do the 0.1% and 0.01% substance limits mean under EU RoHS?

Common mistakes to avoid when documenting EU RoHS 0.1% and 0.01% substance limits

Most mistakes come from using the right percentage at the wrong level of detail. Annex II limits are material-level values, so a finished-product calculation can hide a nonconforming coating, solder, plastic, or cable material.

  • Do not apply 0.1% to cadmium; Annex II lists cadmium at 0.01%.
  • Do not average a restricted substance across a component or finished EEE when separable homogeneous materials should be checked individually.
  • Do not forget DEHP, BBP, DBP, and DIBP when reviewing phthalate-relevant polymers; they are listed in Annex II at 0.1%.
  • Do not rely on an exemption unless the exact material use, product category, and exemption timing still match Annex III or Annex IV.
  • Do not reuse supplier declarations after a material, coating, cable, adhesive, solder, or supplier revision changes unless the declaration still covers the changed material.

What should teams do before a RoHS exemption expires?

What should teams do before a RoHS exemption expires?

Start with the legal entry, not with a supplier statement. RoHS exemptions are tied to a listed application in Annex III or Annex IV, and the Directive allows those lists to be adapted to scientific and technical progress.

For each product that depends on an exemption, record the Annex entry number, exact wording, EEE category, restricted substance, homogeneous material or component use, expiry date, renewal status, and technical-file evidence. If the application no longer matches the exemption wording, treat the product as needing a new compliance path.

Do not build a current-status table unless it is sourced from the current consolidated Directive, the official Commission exemptions list, or the delegated directive that changed the relevant entry.

  • Assign one owner to verify the current Annex wording and expiry date against the official source.
  • Confirm whether a renewal application was filed at least 18 months before the exemption expires.
  • If no renewal is available or the renewal is rejected, prepare a redesign, substitution, qualification, or market-withdrawal decision before the transition period ends.
  • Keep the expiry review with the EU declaration of conformity, technical documentation, supplier evidence, and change-control record.

How RoHS exemption timing works

Article 5 sets the renewal clock. A renewal application must be submitted no later than 18 months before the exemption expires, and the existing exemption remains valid until the Commission takes a decision on that renewal application.

The Commission implementation page states that RoHS exemption decisions currently take 18 to 24 months from the application date. It also describes the evaluation sequence: technical and scientific assessment with stakeholder consultation, draft delegated act feedback, WTO Technical Barriers to Trade notification, and European Parliament and Council scrutiny.

The maximum validity period depends on the Annex and category. For Annex III exemptions listed as at 21 July 2011, unless a shorter period is specified, RoHS sets 5 years for categories 1 to 7 and 10, 7 years for categories 8 and 9 from the relevant Article 4(3) dates, and 5 years for category 11 from 22 July 2019. Annex IV exemptions listed as at 21 July 2011 have a renewable maximum validity period of 7 years from the relevant Article 4(3) dates unless a shorter period is specified.

  • Use the specific Annex entry to calculate the practical review date; do not assume one expiry rule covers every exemption.
  • Open an independent review before the 18-month renewal deadline so engineering can assess substitutes and procurement can qualify suppliers.
  • When a renewal is pending, record the application reference and Commission process source rather than relying on an informal status note.
  • When a delegated directive changes an entry, update product files, supplier requests, and customer-facing compliance statements together.

Evidence to keep with an exemption-expiry review

A useful record should let a reviewer see why the product can still be placed on the EU market, or why it needs redesign before the exemption lapses. Keep the decision tied to the exact exemption wording and product configuration.

For technical documentation, EN IEC 63000 is the harmonised standard cited for assessing electrical and electronic products with respect to restricted substances. Use it as the structure for supplier evidence, material declarations, test reports where needed, and the rationale for relying on an exemption.

  • Current Annex III or Annex IV source used for the expiry date and wording.
  • Product, component, material, and EEE category mapping showing why the exemption applies.
  • Supplier declarations, material declarations, test reports, or engineering analysis supporting the restricted-substance position.
  • Renewal application status, Commission decision status, or rejection transition-period note if relevant.
  • Substitution or redesign assessment, including why immediate substitution is or is not technically practicable for the application.

Common expiry mistakes

The main risk is treating an old exemption reference as a standing permission. RoHS exemptions can be renewed, amended, or deleted, and the Commission reassesses them against substitution, health, environmental, consumer-safety, socioeconomic, and innovation considerations.

A supplier declaration is not enough if it only says the part is RoHS compliant. The declaration must connect the part, material, substance, and exemption wording that the finished product relies on.

  • Do not use an expired Annex entry without checking whether a renewal application keeps it valid pending a Commission decision.
  • Do not reuse an exemption for a different product category, material application, or substance unless the Annex wording actually covers it.
  • Do not cite local files, scraped filenames, or private working notes as public sources; cite the official external URL used for the decision.
  • Do not wait for the listed expiry date before starting redesign work; the Commission page reports that decisions currently take 18 to 24 months.

When can RoHS spare parts use transition rules?

When can spare parts rely on a RoHS transition rule?

Start with the exact role of the part. RoHS defines a spare part as a separate part of EEE that can replace a part of EEE, where the EEE cannot function as intended without it and functionality is restored or upgraded when the part is replaced.

Article 4(4) keeps the restriction from applying to cables or spare parts used to repair, reuse, update functionality, or upgrade capacity of specified legacy EEE. The relevant legacy dates are: EEE placed on the market before 1 July 2006; medical devices before 22 July 2014; in vitro diagnostic medical devices before 22 July 2016; monitoring and control instruments before 22 July 2014; industrial monitoring and control instruments before 22 July 2017; and other EEE newly brought into RoHS scope before 22 July 2019.

There is also a narrow exemption for EEE that benefited from an exemption and was placed on the market before that exemption expired, but only as far as that specific exemption is concerned. That makes the exemption entry, expiry date, product placement date, and spare-part use case essential facts.

  • Do not treat repair stock as automatically outside RoHS; Article 4(1) expressly includes spare parts.
  • Match the spare part to the supported EEE category and the supported product's original EU placing-on-the-market date.
  • If relying on a past Annex exemption, record the exact Annex entry and show that the relevant EEE was placed on the market before that exemption expired.
  • If the spare part is newly sourced and no legacy or Annex rule applies, assess the part against the RoHS restricted substances at homogeneous-material level.

When can RoHS spare parts use transition rules?

What are the reused spare-part cutoff dates?

Article 4(5) is narrower than the general spare-part transition rule. It applies only where reuse happens in auditable closed-loop business-to-business return systems and the reuse of spare parts is notified to the consumer.

For reused spare parts, the recovered-from and used-in dates must both fit the Directive. Reused parts recovered from EEE placed on the market before 1 July 2006 may be used in EEE placed on the market before 1 July 2016. Reused parts recovered from medical devices or monitoring and control instruments placed before 22 July 2014 may be used in EEE placed before 22 July 2024. Reused parts recovered from in vitro diagnostic medical devices placed before 22 July 2016 may be used in EEE placed before 22 July 2026. Reused parts recovered from industrial monitoring and control instruments placed before 22 July 2017 may be used in EEE placed before 22 July 2027. Reused parts recovered from other EEE that was outside RoHS 1 scope and placed before 22 July 2019 may be used in EEE placed before 22 July 2029.

  • Keep evidence that the return system is auditable and business-to-business.
  • Keep the customer or consumer notification record for each reuse of parts.
  • Record both sides of the date test: the EEE from which the part was recovered and the EEE in which the part is used.
  • Do not apply the reused-part route to ordinary new replacement stock.

How do Annex exemptions affect spare parts?

Article 4(6) excludes applications listed in Annex III and Annex IV from the Article 4(1) restriction. Those exemptions are application-specific and time-limited; they should not be treated as product-wide approval.

Some Annex IV entries expressly mention spare parts. For example, Annex IV includes an entry for lead, cadmium, hexavalent chromium, and PBDE in recovered spare parts used for repair or refurbishment of certain medical devices, in vitro diagnostic medical devices, or electron microscopes, with auditable closed-loop B2B reuse and customer notification. That entry expired on 21 July 2021 for medical devices other than in vitro diagnostic medical devices, 21 July 2023 for in vitro diagnostic medical devices, and 21 July 2024 for electron microscopes and their accessories.

Annex IV also includes a later entry for DEHP, BBP, DBP, and DIBP in spare parts recovered from and used for repair or refurbishment of medical devices, in vitro diagnostic medical devices, and their accessories, under the same closed-loop and notification conditions. The consolidated Directive lists that entry as expiring on 21 July 2028.

  • Use the exact Annex entry, not a generic material family description.
  • Check whether the entry is in Annex III or Annex IV and whether it applies to the product category at issue.
  • Track expiry and renewal status before each repair-stock release or service bulletin.
  • Where a renewal application was submitted on time, Article 5 says the existing exemption remains valid until the Commission decides.

What evidence should a spare-parts decision file contain?

A useful spare-parts decision file should let a reviewer re-run the RoHS logic without interviewing the service team. The key facts are the spare part identity, supported EEE identity, product category, placement dates, whether the part is new or recovered, and the exact legal route used.

For ordinary compliant spare parts, keep supplier declarations, material declarations, restricted-substance assessment, and any test evidence used to assess homogeneous materials. For transition or reused-part cases, add placement-date evidence, return-system controls, customer notification proof, and the Annex exemption register if an exemption is being relied on.

  • Tie every spare-part SKU to the finished EEE or installed base it supports.
  • Retain the EU declaration of conformity and technical documentation for the EEE where required by the manufacturer's or importer's RoHS obligations.
  • Use EN IEC 63000 where relevant for the technical-documentation method rather than relying on informal supplier emails alone.
  • Reopen the file after a supplier, material, part design, supported product, Annex exemption, or harmonised-standard change.

Which EEE is in scope under EU RoHS?

Which electrical and electronic equipment is in scope under EU RoHS?

A product is in RoHS scope when it meets the Directive's definition of electrical and electronic equipment, falls within one of the Annex I categories, is placed or made available on the EU market, and is not covered by an Article 2(4) exclusion.

The definition is broader than products whose main purpose is electrical. The Commission FAQ explains that a product can be EEE where an electric function is only a minor but intended and integral function, such as a gas cooker with an electrical clock or petrol-powered equipment with an electric spark for ignition.

Do not stop at a broad product label. A finished product, a separately marketed cable, a component sold as a finished EEE product, or a consumable with an EEE constituent can each need its own RoHS scope analysis.

  • Start with Article 3: does the product need electric currents or electromagnetic fields for at least one intended function, or generate, transfer, or measure them?
  • Confirm the voltage design limit in the EEE definition: not exceeding 1,000 V AC or 1,500 V DC.
  • Assign the product to one of the 11 Annex I categories, including category 11 for other EEE not covered by categories 1 to 10.
  • Check Article 2(4) exclusions, including large-scale stationary industrial tools, large-scale fixed installations, means of transport except non-type-approved electric two-wheel vehicles, active implantable medical devices, certain photovoltaic panels, business-to-business R&D-only equipment, and pipe organs.
  • If the product has both excluded and in-scope uses, treat it as in scope unless the evidence shows it is specifically designed and made available only for an excluded use.

Which EEE is in scope under EU RoHS?

Scope questions that usually change the answer

RoHS scope often turns on how the product is placed on the market, not only on what it contains. The same physical item may be assessed differently if it is sold as a finished EEE product, built into another EEE, sold only as a component for integration, or designed solely for an excluded application.

The Commission FAQ also draws a distinction between electrical parts that are integrated into the product's intended function and detachable EEE that can be separated and used as a fully functional product. That distinction matters for furniture with lighting, cards and boards, consumables, RFID tags, and similar mixed products.

  • Finished EEE: if placed on the EU market for direct use by an end user and it meets the EEE definition, assess it under RoHS.
  • Components and parts: parts used in finished in-scope EEE must meet Article 4 substance restrictions, including non-electrical parts such as fasteners or plastic cases, but components do not automatically need separate CE marking.
  • Cables: cables are generally in RoHS scope unless they belong to EEE or a combination of EEE outside scope; external cables placed on the market separately need their own scope and conformity treatment.
  • Consumables: consumables are in scope only where they include an equipment constituent that meets the EEE definition, such as the Commission FAQ's printer-cartridge example.
  • Professional or industrial use: RoHS does not generally distinguish consumer from professional EEE, although specific Article 2 exclusions or timing rules may apply.
  • Multiple use: EEE with at least one intended in-scope use must comply; excluded-use evidence needs to show the product is made available only for the excluded use.
