REACH is not a certification in the traditional sense. It is a European Union regulation that governs how chemical substances are manufactured, imported, and used. The acronym stands for Registration, Evaluation, Authorisation, and Restriction of Chemicals. When companies or products are described as “REACH certified” or “REACH compliant,” it means they meet the requirements of this regulation, not that they passed a third-party certification program like ISO or UL.
Why REACH Exists
REACH entered into force in 2007 as the EU’s primary law for protecting human health and the environment from hazardous chemicals. It applies across all EU member states plus Iceland, Liechtenstein, and Norway. The regulation shifted the burden of proof: instead of governments having to demonstrate that a chemical is dangerous, companies must prove their substances can be used safely before placing them on the market.
The European Chemicals Agency (ECHA), based in Helsinki, administers REACH. It maintains the databases, evaluates registrations, and publishes the lists of restricted and high-concern substances that drive most of the compliance work companies do.
The Four Pillars of REACH
Each letter in the acronym represents a distinct regulatory process.
Registration requires any company manufacturing or importing a chemical substance into the EU in quantities exceeding one metric ton per year to submit a dossier to ECHA. The dossier includes data on the substance’s properties, hazards, and safe use conditions. Companies registering the same substance are expected to collaborate and share data rather than duplicate testing. There are four tonnage bands (1–10, 10–100, 100–1,000, and over 1,000 tonnes per year), and higher volumes require more extensive safety data.
Evaluation is where ECHA reviews submitted registration dossiers for compliance and completeness. EU member states can also select specific substances for deeper scrutiny when there are initial concerns about risks to health or the environment.
Authorisation targets the most hazardous chemicals. Substances identified as being of “very high concern” are placed on the Candidate List, which currently contains 247 entries. Some entries cover groups of chemicals, so the actual number of affected substances is higher. Companies wanting to continue using these substances must apply for specific authorisation and demonstrate that risks are adequately controlled or that the social and economic benefits outweigh the risks.
Restriction sets conditions or outright bans on the manufacture, sale, or use of dangerous substances. REACH Annex XVII contains the full list of restrictions, covering chemicals like asbestos, lead compounds, mercury compounds, cadmium, certain phthalates, chromium VI compounds, and polycyclic aromatic hydrocarbons, among many others.
What Makes a Substance “Very High Concern”
REACH defines specific criteria for flagging a chemical as a Substance of Very High Concern (SVHC). A substance qualifies if it is carcinogenic, mutagenic, or toxic to reproduction. It also qualifies if it is persistent, bioaccumulative, and toxic, meaning it doesn’t break down easily in the environment, accumulates in living organisms, and causes harm. Substances that are very persistent and very bioaccumulative meet the threshold even without separate toxicity data.
Beyond those categories, REACH includes a catch-all provision for chemicals with probable serious effects on health or the environment that raise an equivalent level of concern. This has been used to flag endocrine disruptors (chemicals that interfere with hormone systems) and respiratory sensitizers.
Why People Search for “REACH Certification”
The confusion is understandable. Many product safety standards work through certification: a lab tests a product, issues a certificate, and the manufacturer can display a mark. REACH works differently. There is no single “REACH certificate” issued by ECHA or any accredited body. Instead, compliance is demonstrated through registration dossiers submitted to ECHA, safety data sheets provided along the supply chain, and internal documentation showing that restricted substances are below legal thresholds.
When a supplier provides a “REACH certificate” or “REACH declaration,” they are typically issuing a self-declaration. This document states that their product complies with the relevant REACH requirements, particularly the restrictions in Annex XVII and the obligation to disclose SVHCs above 0.1% by weight. These declarations are useful for supply chain communication, but they are not issued or verified by ECHA itself.
Who Has to Comply
REACH obligations fall on several types of companies. Manufacturers and importers who bring chemical substances into the EU bear the primary registration burden. But “downstream users,” companies that buy and use chemicals in their products or processes, also have responsibilities. Downstream users must follow the risk management measures outlined in safety data sheets they receive from suppliers. If their specific use of a chemical isn’t covered by the supplier’s registration, they need to report that gap to ECHA within six months.
Companies that produce or import finished articles (think electronics, textiles, or toys) must notify customers if those articles contain a Candidate List substance above 0.1% concentration by weight. If the total amount of that substance across all articles exceeds one tonne per year, the company must also notify ECHA. This is why product manufacturers outside the EU who export to Europe often need to engage with REACH, even though they aren’t directly registering chemicals.
Safety Data Sheets Under REACH
The safety data sheet (SDS) is the primary tool for communicating chemical hazard information through the supply chain. REACH specifies a standardized 16-section format for these documents, covering everything from hazard identification and first aid measures to storage conditions and disposal considerations. Any company supplying a hazardous substance or mixture must provide an SDS to its customers, and it must be written in the official language of the country where the product is sold.
These documents aren’t just paperwork. They contain the specific exposure scenarios and risk management measures that downstream users are legally required to follow. When new hazard information becomes available or a restriction changes, companies must update and redistribute their safety data sheets without delay.
Costs of Compliance
Registering substances with ECHA involves fees that vary by company size and data requirements. Large companies face standard fees that are set to increase by 19.5% starting in November 2025. Small and medium-sized enterprises pay reduced fees, but they must apply for company size validation before submitting their dossiers to qualify for the discount. Beyond registration fees, the real cost for many companies lies in generating the toxicological and environmental data required for higher tonnage bands, which can involve extensive laboratory testing.
REACH Compliance for Non-EU Companies
REACH places the registration obligation on the EU-based manufacturer or EU-based importer, not on the foreign producer. If you manufacture chemicals or products outside the EU and export to European customers, your EU importer is legally responsible for registration. Alternatively, you can appoint an “Only Representative” based in the EU to handle registration on your behalf, which shifts the obligation away from each individual importer.
This structure is why non-EU companies often hear about REACH compliance from their European buyers. A customer in Germany or France may request a REACH declaration, test reports for restricted substances, or confirmation that no Candidate List SVHCs are present above 0.1%. Meeting these requests is a practical market access requirement, even though the regulation technically governs EU-based entities.
