REACH vs RoHS: What Each Rule Means for Chemical Products
REACH covers almost every chemical substance, mixture and article on the EU market; RoHS covers only restricted substances in electrical and electronic equipment. A grease, adhesive or coating sold on its own falls under REACH, not RoHS. Once it is built into equipment, RoHS limits apply to it as one material of that equipment.
RoHS Annex II restricts 10 substances to 0.1% by weight in each homogeneous material, and cadmium to 0.01% (Directive 2011/65/EU, Annex II, as amended by Delegated Directive 2015/863).
REACH requires a manufacturer or importer of a substance, on its own or in mixtures, to register it at one tonne or more per year (Regulation 1907/2006, Article 6).
A supplier of an article containing a Candidate List substance above 0.1% weight by weight (w/w) must give the recipient at least the substance name, and must answer a consumer's request free of charge within 45 days (Regulation 1907/2006, Article 33).
For a product made of several articles, the 0.1% w/w threshold applies to each article, not to the whole product (CJEU, Case C-106/14, 2015).
This comparison covers the EU texts as consolidated on 22 June 2026 (REACH) and 1 July 2026 (RoHS). It does not cover UK REACH, China RoHS, K-REACH or US TSCA, which keep their own lists and thresholds, or the CLP labeling rules for mixtures.
How do REACH and RoHS differ?
REACH and RoHS differ in what they cover, what triggers them and who proves compliance. REACH, the Registration, Evaluation, Authorisation and Restriction of Chemicals regulation, applies to the manufacture, placing on the market and use of substances on their own, in mixtures or in articles (Regulation 1907/2006, Article 1). RoHS, the Restriction of Hazardous Substances directive, lays down rules restricting hazardous substances in electrical and electronic equipment (EEE) (Directive 2011/65/EU, Article 1). Its list holds 10 substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers and four phthalates, DEHP, BBP, DBP and DIBP (European Commission RoHS page, accessed 2026). The European Commission's guidance puts it plainly: "RoHS and REACH are two different acts with different scopes and objectives." (European Commission RoHS 2 FAQ, 2012).
The table below shows which rule sets each duty for a grease, adhesive or coating used in electronics.
Obligation | REACH | RoHS |
|---|---|---|
Product sold in a drum, tube or cartridge | In scope as a mixture: registration of its substances, safety data sheet, restrictions | Not in scope: a consumable that does not meet the EEE definition is not equipment (European Commission RoHS 2 FAQ, 2012) |
Same material inside finished equipment | Part of an article; information duty if a Candidate List substance exceeds 0.1% w/w of the article (Regulation 1907/2006, Article 33) | One homogeneous material of the EEE; Annex II limits apply to it (Directive 2011/65/EU, Article 4) |
Restricted list | Annex XVII restrictions, Annex XIV authorisation, Candidate List information duties | 10 substances in Annex II (Delegated Directive 2015/863) |
Threshold basis | 0.1% w/w of each article, for Article 33 Candidate List information (CJEU, Case C-106/14, 2015); Annex XVII limits are set per substance (Regulation 1907/2006, Article 67) | 0.1% by weight per homogeneous material, 0.01% for cadmium (Directive 2011/65/EU, Annex II) |
Quantity trigger | Registration at one tonne or more per year per manufacturer or importer (Regulation 1907/2006, Article 6) | No quantity threshold in the directive; applies to EEE placed on the market (Directive 2011/65/EU, Article 4) |
Proof document | Safety data sheet for a hazardous mixture, and on request for an unclassified mixture with certain listed substances at 0.1% or 1% by weight or more (Regulation 1907/2006, Article 31); Article 33 information for an article | Technical documentation and EU declaration of conformity, kept 10 years (Directive 2011/65/EU, Article 7) |
The row that changes the most work is the threshold basis: RoHS applies 0.1% by weight to each homogeneous material, while REACH applies 0.1% w/w to each article (Directive 2011/65/EU, Annex II; CJEU, Case C-106/14, 2015).
Does RoHS apply to greases, adhesives and coatings used in electronics?
RoHS applies to greases, adhesives and coatings only as part of electrical and electronic equipment placed on the EU market; sold on their own, they are not EEE. The directive defines EEE as equipment that depends on electric currents or electromagnetic fields to work properly, designed for a voltage rating not exceeding 1 000 volts AC and 1 500 volts DC (Directive 2011/65/EU, Article 3). A grease in a drum needs no current to do its job, so it is not equipment. The Commission guidance confirms that consumables that do not meet the EEE definition, such as soap powder, are not in scope (European Commission RoHS 2 FAQ, 2012).
Inside a finished device, the picture changes. The Commission states that EEE can only meet the substance requirements "if all its components and parts meet the substance restriction requirements of RoHS 2" (European Commission RoHS 2 FAQ, 2012). A cured adhesive bead, a conformal coating or a contact grease then counts as a homogeneous material, which the directive defines as one material of uniform composition throughout, or a combination that cannot be separated mechanically (Directive 2011/65/EU, Article 3). The Annex II maximum concentration values are applied to each homogeneous material individually (European Commission RoHS 2 FAQ, 2012), unless an Annex III or IV exemption applies. If two coating layers can be separated by physical methods, they are two homogeneous materials (European Commission RoHS 2 FAQ, 2012).
When does REACH matter more for a chemical product?
REACH matters more for any grease, adhesive or coating sold as a product, because REACH, not RoHS, sets the duties for the mixture itself. Any manufacturer or importer of a substance, on its own or in mixtures, in quantities of one tonne or more per year must register it with the European Chemicals Agency (ECHA) (Regulation 1907/2006, Article 6). The supplier of a mixture classified as hazardous under the CLP Regulation must provide a safety data sheet (SDS) (Regulation 1907/2006, Article 31).
REACH also restricts and authorizes substances in ways that reach the product before it ever meets a circuit board. A substance in Annex XVII may not be manufactured, placed on the market or used unless it complies with the conditions of that restriction, whether on its own, in a mixture or in an article (Regulation 1907/2006, Article 67). A substance in Annex XIV may not be placed on the market or used without an authorisation or an exemption for that use (Regulation 1907/2006, Article 56).
REACH also covers the many machines RoHS leaves out. RoHS does not apply to large-scale stationary industrial tools, large-scale fixed installations or means of transport for persons or goods, except electric two-wheel vehicles that are not type-approved, among other exclusions (Directive 2011/65/EU, Article 2). A lubricant or sealant used in those machines still answers to REACH, because REACH applies on its own scope (Regulation 1907/2006, Article 1) and RoHS applies "without prejudice to" REACH (Directive 2011/65/EU, Article 2).
Can a product be RoHS compliant but not REACH compliant?
Yes, a product can be RoHS compliant and still break REACH, because REACH covers substances RoHS does not list and measures them on a different basis. A device can keep all 10 Annex II substances below their limits and still contain a substance of very high concern (SVHC) from the Candidate List above 0.1% w/w in one of its articles. In that case its supplier must give the recipient enough information to allow safe use, as a minimum the name of the substance (Regulation 1907/2006, Article 33). A RoHS declaration says nothing about that duty.
The basis of the threshold widens the gap. For a product made of several articles, the Court of Justice of the European Union (CJEU) ruled that the 0.1% w/w threshold is checked for each article, not for the assembled product (CJEU, Case C-106/14, 2015). RoHS checks each homogeneous material instead (Directive 2011/65/EU, Annex II), so the same device is measured twice, on two different bases.
The reverse also holds. A grease with a complete REACH SDS can still make a finished device fail RoHS if it carries a restricted substance above the Annex II limit, because REACH paperwork for a mixture does not test that limit. The Commission sums up the relationship: "RoHS 2 does not affect the application of REACH, and vice-versa, with regard to the restriction of substances in EEE" (European Commission RoHS 2 FAQ, 2012).
Which documents prove REACH and RoHS compliance?
No single certificate proves both REACH and RoHS compliance: RoHS is shown by the equipment maker's technical documentation and EU declaration of conformity, and REACH by the SDS for a mixture and Article 33 information for an article. Under RoHS, the manufacturer draws up technical documentation, carries out internal production control, draws up the EU declaration of conformity and affixes the CE marking, then keeps the documentation and declaration for 10 years after the equipment is placed on the market (Directive 2011/65/EU, Article 7). By drawing up the declaration, the manufacturer assumes responsibility for compliance (Directive 2011/65/EU, Article 13).
The Commission published the reference of EN IEC 63000:2018 as the harmonised standard for this technical documentation, covering materials, components and equipment, and it replaced EN 50581:2012 (Implementing Decision 2020/659). A chemical supplier's material declaration feeds that file; RoHS puts no declaration duty on the supplier of a grease sold on its own.
Under REACH, the SDS travels with a hazardous mixture (Regulation 1907/2006, Article 31). An unclassified mixture still needs an SDS on request when it contains a Candidate List substance at 0.1% by weight or more, among other cases (Regulation 1907/2006, Article 31(3)). For articles, Article 33 information goes to the recipient, and since 5 January 2021 article suppliers also send that information to ECHA (Directive 2008/98/EC, Article 9). The file is not a shield: if enforcement analysis finds a violation, the manufacturer bears full responsibility even after assessing the equipment according to the standard (European Commission RoHS 2 FAQ, 2012).
What drives the REACH and RoHS compliance effort over a product's life?
The REACH and RoHS compliance effort over a product's life is driven by changes: changes to the regulated lists, to formulations and suppliers, and to the number of materials in each device. The one-time declaration is the smaller part.
List changes come first. ECHA must publish and update the Candidate List on its website without delay after each decision to include a substance (Regulation 1907/2006, Article 59), so an article that met Article 33 at launch can trigger a new information duty later. The RoHS Annex II list is reviewed periodically and must stay coherent with REACH Annexes XIV and XVII (Directive 2011/65/EU, Article 6).
Formulation and supplier changes come second. RoHS requires procedures so that series production stays in conformity, and changes in product design or characteristics must be taken into account (Directive 2011/65/EU, Article 7). A reformulated grease or a new coating source therefore means new evidence for every device that uses it.
Material count comes third. Every adhesive, coating, grease and solder is a separate homogeneous material under RoHS, while REACH Article 33 checks Candidate List content against 0.1% w/w of each article (Regulation 1907/2006, Article 33; CJEU, Case C-106/14, 2015), so a device with more chemical materials carries more evidence to keep current. Record keeping comes last: RoHS files stay available for 10 years (Directive 2011/65/EU, Article 7). Matching supplier SDSs, certificates and declarations against both rules for each device is the kind of case Lubinpla structures into one cited document for your review.
FAQ
Do REACH SVHCs and RoHS restricted substances overlap?
Yes, partly. The four phthalates that Delegated Directive 2015/863 added to RoHS Annex II from 22 July 2019 (22 July 2021 for medical devices and monitoring and control instruments), DEHP, BBP, DBP and DIBP, are substances of very high concern under REACH (Delegated Directive 2015/863). Any review of the RoHS list must stay coherent with REACH and take account of REACH Annexes XIV and XVII (Directive 2011/65/EU, Article 6).
Which limit applies when REACH and RoHS both restrict a substance?
The Commission guidance says that when overlaps occur, the strongest restriction, meaning the lowest maximum concentration, should be applied (European Commission RoHS 2 FAQ, 2012).
Do RoHS limits apply to chemicals used only during production?
No. The Commission guidance states that RoHS restrictions apply only to finished EEE, so a restricted substance may be used in the production process as long as other rules allow it and the finished equipment does not contain it above the maximum concentration values (European Commission RoHS 2 FAQ, 2012). REACH still applies to that process chemical.
