REACH Registration (Registration, Evaluation, Authorization and restriction of chemicals)

REACH-Gateway to the EU Chemical Market

The REACH Regulation—Registration, Evaluation, Authorisation, and Restriction of Chemicals is the cornerstone of chemical safety regulation in the European Union. Enacted in 2007 and managed by the European Chemicals Agency (ECHA), REACH ensures that anyone manufacturing or importing more than 1 tonne of a chemical substance per year into the EU is responsible for assessing and managing associated risks.

What Is REACH Registration?

REACH registration is the gateway that authorises substances and mixtures to enter the EU market. It requires:

  • Submission of a dossier via REACH‑IT containing:
  • Physicochemical characteristics
  • Toxicological and ecotoxicological data
  • Exposure assessments and risk management measures
  • A Chemical Safety Report (CSR) for substances ≥ 10 tonnes/year
  • The submission adheres to the principle: “no data, no market”

Importers, manufacturers, distributors, downstream users, and non‑EU entities (via an Only Representative) are all obligated to register.

Objectives

The REACH Regulation aims to: 

  • ensure a high level of protection of human health and the environment against harmful substances
  • assess the safety of chemical substances in use in the EU
  • promote innovation and competitiveness
  • promote alternative (non-animal) methods for the assessment of the hazards of substances
Law

The REACH Regulation (EC 1907/2006) entered into force in 2007 and has since evolved to reflect the advancement of knowledge regarding various chemicals and their properties.

The Commission is currently revising the REACH Regulation, in line with the Commission’s Better Regulation provisions.

It will include a thorough assessment of possible impacts of potential changes to REACH on

  • the protection of human health and the environment
  • the use of animal testing
  • the functioning of the internal market
  • and the competitiveness and innovation of European industry and businesses
REACH Registration process
REACH stipulates that chemical substances that exceed 1 tonne per year per company must be registered with ECHA. In this process, companies must identify the risks linked to the substances they handle and indicate how they manage them. This obligation applies to both substances and mixtures.
Evaluation
ECHA and the Member States then evaluate the information submitted by companies to ascertain whether a given substance poses risks to human health or the environment.
Authorization
The authorization process aims to ensure that substances of very high concern (SVHCs) are progressively replaced by less dangerous substances or technologies where technically and economically feasible alternatives are available.
Restrictions
REACH includes a restriction process for certain substances of very high concern if they pose an unacceptable risk to health or the environment. Such substances may be limited or even banned, if necessary.

Importance of REACH Registration

  1. Protecting Health & Environment
    2. With more than 100,000 chemicals historically used in Europe—and only a small portion fully evaluated—REACH bridges a critical safety gap. Its “no data, no market” approach ensures robust safety data is available before market entry
  1. Ensuring EU Market Access
    2. Any substance manufactured or imported in quantities ≥ 1 tonne/year must be registered—otherwise, access to the EU market is legally blocked
  1. Driving Innovation
    2. REACH encourages innovation by:
    • Promoting safer alternative substances.
    • Incorporating New Approach Methods (NAMs) and reducing animal testing
  1. Boosting Supply Chain Transparency
    2. Downstream users gain access to comprehensive safety information, enhancing responsible handling and compliance throughout the supply chain.
  1. Building Trust and Market Confidence
    2. Compliance reassures regulators, business partners, and consumers—particularly as concerns grow about Substances of Very High Concern (SVHCs)

REACH Registration Workflow

Data Collection: Substance ID, usage, hazard assessment.
Engage with SIEFs: Collaborate with others registering the same substance, sharing data and costs.
Dossier Preparation: Use IUCLID and Chesar to build the dossier and CSR
 Submission via REACH‑IT: Submit through ECHA’s portal.
Evaluation Follow‑Up: Respond to ECHA/member-state requests.
Ongoing Compliance: Keep the dossier current; renew every 10 years as required

Sample Success with Masuu

A non-EU manufacturing client sought entry into the EU market but lacked EU representation, dossier readiness, and SIEF access. We:

  • Became their Only Representative
  • Mapped substance usage and tonnage
  • Negotiated SIEF data access
  • Prepared and submitted a dossier with CSR
  • Managed follow-up through ECHA evaluation

Frequently Asked Questions

REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals and is a key EU regulation for managing chemical safety. It helps protect human health and the environment while ensuring that companies understand and manage the risks associated with the substances they manufacture or import.

Companies that manufacture or import a chemical substance at 1 tonne or more per year per company may have a REACH registration obligation, subject to applicable exemptions. Non-EU manufacturers can also appoint an Only Representative (OR) to manage certain EU REACH responsibilities on their behalf.

A REACH registration dossier generally includes information about the identity and properties of the substance, uses, physicochemical characteristics, toxicological and ecotoxicological data, exposure, and risk management measures. A Chemical Safety Report (CSR) is required for applicable substances at the relevant higher tonnage threshold.

The “No Data, No Market” principle means that companies must provide the required safety information before placing applicable substances on the EU market. Registration helps demonstrate that the risks associated with a substance have been identified and are being appropriately managed.

REACH involves several stages, including registration, evaluation, authorisation, and restriction. ECHA and Member State authorities can evaluate submitted information, while substances of very high concern (SVHCs) may be subject to authorisation or restrictions where risks require additional controls.

The process starts with substance identification, use and tonnage assessment, and collection of relevant safety data. The information is then compiled using tools such as IUCLID and Chesar, followed by preparation of the applicable dossier and CSR and submission through REACH-IT.

Companies registering the same substance may need to work together to share relevant data and registration costs. Masuu Global can support SIEF or joint-submission activities, including data-access discussions, Letters of Access, and cost-sharing arrangements.

An Only Representative is an EU-based entity appointed by an eligible non-EU manufacturer to handle specified REACH registration responsibilities. Masuu Global can support OR activities, including communication with ECHA, SIEF participants, and relevant supply-chain stakeholders.

REACH requires companies to assess the potential health and environmental hazards and risks associated with chemical substances. It also promotes safer alternatives, better supply-chain communication, and the use of alternative approaches that can help reduce unnecessary animal testing.

ECHA or Member State authorities may evaluate the information provided and request additional data or clarification where necessary. Companies must respond appropriately and keep their registration information updated as new scientific, regulatory, or substance information becomes available.

Masuu Global provides end-to-end REACH support, including regulatory applicability and exemption assessments, substance and tonnage mapping, hazard and risk assessment, IUCLID dossier preparation, CSR development, REACH-IT submission, SIEF support, and Only Representative services.

REACH compliance continues after the initial registration. Masuu Global can monitor ECHA regulatory updates, SVHC developments, guidance changes, and evolving chemical safety requirements, while helping clients update their dossiers and compliance strategies as their products, uses, or markets change.
