REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) is the EU’s regulatory framework for chemical safety. It requires companies manufacturing or importing over 1 metric ton of a substance annually into the EU to provide detailed safety and usage data. This ensures human and environmental protection while allowing market access. Non-EU companies must appoint an EU-based Only Representative for compliance.
Key steps to register under REACH:
- Identify the substance: Provide precise details like IUPAC name, CAS number, and composition.
- Submit an inquiry: Use the ECHA REACH-IT portal to check for existing registrations and share data.
- Collect data: Gather safety, environmental, and exposure information based on tonnage.
- Prepare a dossier: Use IUCLID software to compile and submit required information.
- Monitor updates: Stay informed of regulatory changes, like the 2025 revisions requiring polymer registration and Digital Product Passports.
Starting in 2025, registrations will have a 10-year validity, requiring updates for hazard classifications and compliance. Partnering with experienced suppliers can simplify the process by providing accurate documentation and regulatory support.
REACH 2018: Submit your registration dossier
Data Requirements for REACH Registration
REACH registration involves submitting data packages that correspond to the annual tonnage of a substance. Companies must supply detailed information in three key areas: substance identity, safety and environmental data, and exposure scenarios. The level of detail required increases with the tonnage – ranging from basic data for substances between 1 and 10 metric tons per year to extensive studies for those exceeding 1,000 metric tons. Below is a breakdown of these requirements.
Substance Identity and Composition
A complete profile of the substance’s identity is essential. This includes its IUPAC or trade names, CAS number, EC number, molecular or structural formula, and composition details. This ensures regulatory authorities can accurately identify the substance being registered.
The composition must include quantitative details about main constituents, impurities (≥0.1% w/w), and any additives. For complex substances, such as UVCBs (Unknown or Variable composition, Complex reaction products, or Biological materials), companies must also describe the manufacturing process and any variability in composition.
To support these details, analytical data – such as spectra from Nuclear Magnetic Resonance (NMR), Infrared (IR), and Mass Spectrometry (MS), as well as chromatograms – must be provided. This data serves as scientific evidence to confirm the substance’s identity and composition.
Safety and Environmental Data Requirements
The required safety and environmental data depend on the substance’s tonnage band. Basic data, such as melting/freezing points, boiling point, density, vapor pressure, water solubility, partition coefficient (n-octanol/water), flash point, flammability, and explosive or oxidizing properties, is required for lower tonnage bands. At higher tonnage levels, additional studies on stability, reactivity, and other specific properties are necessary.
Toxicological data requirements also increase with tonnage. Depending on the band, companies may need to submit studies on acute toxicity, skin and eye irritation, sensitization, mutagenicity, repeated dose toxicity, and reproductive or developmental toxicity. For substances exceeding 1,000 metric tons per year, carcinogenicity studies may also be required.
| Tonnage Band (metric tons/year) | Data Requirements |
|---|---|
| 1–10 | Basic physicochemical properties, limited toxicological and ecotoxicological data |
| 10–100 | Extended toxicological/ecotoxicological studies and a chemical safety assessment |
| 100–1,000 | Comprehensive toxicological/ecotoxicological data sets and detailed exposure scenarios |
| >1,000 | Long-term studies and a full risk assessment |
Ecotoxicological evaluations include both acute and chronic aquatic toxicity studies, biodegradation testing, bioaccumulation potential, and environmental fate analyses. Starting in 2025, new hazard classes – like endocrine disruptors and persistent, mobile, toxic substances – will require additional data as part of regulatory updates.
Exposure Scenarios and Use Information
Exposure scenarios provide a detailed overview of the substance’s lifecycle, from manufacturing to processing and use, along with the risk management measures in place. This information allows regulators to assess potential human and environmental exposure pathways and determine whether the substance can be used safely under the specified conditions.
Companies must also document all identified uses, whether in industrial processes, professional applications, or consumer products. Clear descriptions of risk management measures to minimize exposure throughout the supply chain are equally critical.
To streamline compliance, Allan Chemical Corporation offers detailed documentation and technical support. They provide customers with accurate specifications, certificates of analysis, and safety data sheets, ensuring smooth REACH compliance.

Step-by-Step REACH Registration Process
The REACH registration process is divided into three key phases, each building on the previous one. Completing these steps thoroughly is essential to avoid delays or rejections from ECHA, which can be both time-consuming and costly.
Substance Identification and ECHA Inquiry
Substance identification is the cornerstone of REACH registration. This involves collecting precise analytical data to confirm the identity, composition, and purity of your chemical. Key details include the IUPAC name, CAS number, EC number, molecular structure, and impurity profiles.
Ensure the accuracy of spectral data, such as NMR, IR, and MS, as well as chromatograms, to confirm the substance’s composition. Any errors in identification can lead to registration rejection, so getting it right from the start is critical.
Once the substance is identified, the next step is submitting an inquiry to ECHA through the REACH-IT portal. This inquiry determines if another company has already registered the substance and facilitates mandatory data sharing. The inquiry dossier must include substance identification details, the proposed tonnage band, and intended uses.
Collaborating with knowledgeable chemical suppliers can simplify this process. For example, Allan Chemical Corporation offers detailed specifications, certificates of analysis, and safety data sheets that support accurate substance identification. Their products meet recognized quality standards like ACS, USP, NF, and FCC, ensuring compliance with ECHA requirements.
After confirming your substance’s identity and submitting the ECHA inquiry, you can move on to the next phase: data collection.
Data Collection and Collaboration
Gathering the necessary data for REACH registration is a demanding process. You’ll need detailed information on physical-chemical properties, toxicological profiles, ecotoxicological data, and exposure scenarios, all tailored to the substance’s tonnage band. This data can be sourced from existing studies, literature reviews, or newly commissioned tests.
Joining a Substance Information Exchange Forum (SIEF) is highly beneficial for companies registering the same substance. These forums allow participants to share data, reduce duplicate testing, and share the costs of required studies. By working together, registrants can meet data requirements more efficiently and at a lower cost.
Navigating SIEF collaboration involves agreeing on study protocols, cost-sharing arrangements, and joint submission strategies. Engaging regulatory consultants or partnering with experienced suppliers can help streamline this complex process.
Only commission new tests if there are gaps in the existing data. For substances exceeding 100 metric tons per year, comprehensive toxicological and ecotoxicological studies may be necessary, which can take 12–18 months to complete.
Once all required data is gathered, proceed to dossier preparation and submission.
Dossier Preparation and Submission
The dossier is prepared using IUCLID software, which organizes all required data into standardized formats for ECHA’s review. This software ensures that each data requirement is addressed and formatted correctly for electronic submission.
Your dossier must include:
- Substance identity details
- Safety and environmental data
- Chemical safety assessments for substances over 10 metric tons per year
- Detailed exposure scenarios for each identified use
Dossier preparation can take 2–4 months for simpler substances, but more complex chemicals or those with limited data may require additional time.
Submit your completed dossier via the REACH-IT portal, along with the necessary fee. ECHA will perform a completeness check to verify that all mandatory fields are filled. If the dossier passes this review, a registration number is assigned, allowing the legal manufacture or import of the substance within the EU.
ECHA may request additional information during their evaluation, especially for substances with higher tonnage or concerning hazard profiles. Responding quickly to these requests is essential to maintain compliance, particularly with the upcoming 2025 REACH revisions, which introduce 10-year validity periods for registrations.
Allan Chemical Corporation offers support throughout this process. Their Regulatory Document Coordinator helps clients gather the required documentation and ensures accuracy in dossier preparation, reducing the likelihood of delays or additional information requests from ECHA.

REACH Timelines and 2025 Updates
Keeping track of REACH timelines is critical to staying compliant with the 2025 updates. These changes require a thorough review of existing registrations to ensure alignment with the updated requirements.
Registration Deadlines and Timelines
REACH deadlines depend on the type of substance. For phase-in substances – those listed in the European Inventory of Existing Commercial Chemical Substances (EINECS) and pre-registered before December 2008 – deadlines are extended based on tonnage bands[4]. In contrast, non-phase-in substances must be registered before they are imported or manufactured in quantities exceeding 1 metric ton per year[4].
2025 REACH Revisions
The 2025 updates introduce a 10-year validity period for registrations. After this period, companies must renew their registrations. The European Chemicals Agency (ECHA) may revoke registration numbers if dossiers are not updated or fail ad-hoc completeness checks[1][2]. Businesses are required to update dossiers with new hazard data, including changes in substance classification or Substances of Very High Concern (SVHC) status, to avoid invalidation[1][2].
The revisions also expand registration requirements. Polymers and low-tonnage substances that were previously exempt now fall under the scope of registration if they exceed 1 metric ton per year. Additionally, new hazard classes, such as endocrine disruptors and persistent, mobile, toxic (PMT) substances, demand more controls and data submissions[3]. The introduction of Digital Product Passports (DPPs) will improve the sharing of compliance data across the supply chain, enhancing traceability and transparency[2].
Enforcement will also see major changes. With increased audits, dossier validation checks, and harmonized penalties across EU Member States, compliance expectations are rising. ECHA’s REF-10 enforcement project revealed an 18% non-compliance rate in consumer products. Furthermore, the SVHC Candidate List was updated in June 2025 to include 250 substances, requiring companies to identify concentrations above 0.1% w/w in their articles[2].
Table: Old vs. New REACH Requirements
| Requirement | Pre-2025 REACH | 2025 REACH Revision |
|---|---|---|
| Registration Validity | Indefinite | 10-year validity, renewal required |
| Polymers Registration | Generally exempt | Registration required if >1 metric ton/year |
| Dossier Update Obligation | Required on change | Mandatory on new hazard data/SVHC status |
| Hazard Classes | Limited existing classes | Expanded to include endocrine disruptors and PMTs |
| Digital Compliance | Paper/electronic files | Enhanced via Digital Product Passports |
| Enforcement Approach | National, less harmonized | More EU-level audits, harmonized penalties |
To prepare for these changes, companies should start reviewing their chemical portfolios, setting up processes for regular dossier updates, and organizing compliance documentation for digital reporting. Allan Chemical Corporation offers regulatory expertise and can assist with up-to-date compliance documentation and dossier preparation, ensuring a smooth transition to the new requirements.
