EU REACH Explained: The Ultimate Guide

Overview

EU REACH is a mandatory regulation that governs the production, import, and use of chemical substances within the European Union. It applies to substances on their own, in mixtures, and in articles, and covers a wide range of industries.

The regulation is designed to ensure that companies take responsibility for understanding and managing the risks posed by chemicals. Substances manufactured or imported in quantities of one tonne or more per year must be registered with the European Chemicals Agency, forming the foundation of EU REACH compliance.

As of 2018, it was estimated that up to 100,000 substances would be registered under REACH, highlighting the scale and industry-wide impact of the regulation.

What is EU REACH?

The EU’s REACH Regulation — Registration, Evaluation, Authorisation and Restriction of Chemicals — is one of the most comprehensive chemical safety laws in the world. It stands for:

• Registration – Companies manufacturing or importing one tonne or more of a chemical per year must register it with the European Chemicals Agency (ECHA). They must submit data on properties, hazards, uses, and safe handling. Without registration, the substance cannot be marketed (“no data, no market”).
• Evaluation – ECHA and Member States review registration dossiers and testing proposals to verify compliance and determine whether further information is needed to clarify potential risks.
• Authorisation – Certain hazardous substances, known as Substances of Very High Concern (SVHCs), require special permission for use. Authorisation is granted only if risks are adequately controlled or if socio-economic benefits outweigh them, and no suitable alternatives exist.
• Restriction – Limits or bans may be placed on the manufacture, use, or sale of substances posing unacceptable risks, applicable to all actors in the supply chain.

Together, REACH ensures chemicals are managed safely throughout their life cycle.

History and Rationale

Before REACH, EU chemical laws were fragmented, with a key gap: most “existing” substances (on the market before 1981) had never been systematically tested for safety. Public concern over persistent, bioaccumulative, and toxic substances drove the 1998 White Paper call for reform, based on the principle of “no data, no market” and shifting the burden of proof from regulators to industry.

REACH introduced a single, harmonised system covering substances in their pure form, in mixtures, and in articles. It requires companies to provide safety data, promotes substitution of hazardous chemicals, and empowers the European Chemicals Agency (ECHA) to oversee compliance and ensure transparency.

Today, REACH is not only the backbone of EU chemical safety but also a global benchmark, inspiring similar laws in Korea, Turkey, and beyond – proving that strong regulation can drive both protection and innovation.

Objectives of EU REACH

Key objectives of EU REACH include:

• Improving knowledge and transparency around chemical substances
• Promoting safer alternatives to hazardous chemicals
• Strengthening risk management across supply chains
• Supporting innovation within the chemical industry

By shifting responsibility to industry, EU REACH encourages companies to proactively manage chemical safety and reduce potential risks.

How Does EU REACH Work?

EU REACH operates through a structured process that ensures chemicals are assessed, controlled, and managed effectively throughout their lifecycle.

Registration

Registration is the cornerstone of EU REACH. Companies that manufacture or import chemical substances in quantities exceeding one tonne per year must submit a registration dossier to ECHA.

This dossier includes:

• Substance identity and properties
• Hazard classification and labelling
• Toxicological and ecotoxicological data
• Exposure scenarios and safe use guidance

Failure to complete registration means the substance cannot be legally placed on the EU market.

Evaluation

Once registered, substances may be evaluated by ECHA or national authorities to ensure compliance and assess potential risks.

Evaluation includes:

• Dossier Evaluation – Checking that the submitted information meets requirements
• Substance Evaluation – Investigating substances that may pose risks

Authorities may request additional data to clarify uncertainties and ensure robust risk assessment.

Authorisation

Authorisation applies to substances of very high concern (SVHCs), including those that are carcinogenic, mutagenic, toxic for reproduction, or persistent in the environment.

To continue using these substances, companies must apply for authorisation and demonstrate that:

• Risks are adequately controlled, or
• Socio-economic benefits outweigh the risks, and no suitable alternatives exist

This process aims to phase out hazardous substances and encourage safer alternatives.

Restriction

Restrictions are used to manage unacceptable risks by limiting or banning the manufacture, use, or placing on the market of certain hazardous substances.

Restrictions can apply to specific uses or across entire product categories, ensuring consistent risk control across the EU.

REACH’s Effect on Companies

Achieving REACH compliance is essential, as non-compliance can affect:

• Market Access: Non-compliance risks losing access to EU markets and limiting growth.
• Reputation Risk: Your brand could suffer if you do not meet your regulatory obligations or if your products harm people or the environment.
• Supply Chain Disruptions: Challenges can cause delays with lasting effects on the supply chain.

Recent enforcement changes highlight the importance of proactive compliance to protect your business and ensure continued market access.

REACH Fundamentals and Process Workflows

Understanding the REACH process is essential for achieving compliance. The typical workflow includes:

1. Substance Identification – Determine whether REACH applies
2. Data Collection – Gather existing data on substance properties
3. Gap Analysis – Identify missing information
4. Testing and Assessment – Generate required data where needed
5. Dossier Preparation – Compile registration documentation
6. Submission to ECHA – Submit via REACH-IT system
7. Evaluation and Follow-Up – Respond to authority requests
8. Ongoing Compliance – Maintain and update dossiers as required

This structured approach helps organisations manage regulatory obligations effectively and minimise compliance risks.

EU REACH vs UK REACH

Following the UK’s departure from the European Union, a separate UK REACH framework was established.

While both systems share similar principles, key differences include:

Companies trading across the EU and UK must ensure compliance with both EU REACH and UK REACH, which can increase regulatory complexity.

Implications for Consumers and Industry

EU REACH plays a critical role in protecting consumers and the environment.

For consumers:

• Improved safety of products through stricter chemical controls
• Access to information about hazardous substances

For industry:

• Increased responsibility for chemical risk management
• Greater transparency and accountability
• Incentives to develop safer and more sustainable alternatives

Environmental protection is also a key outcome, with REACH helping to reduce pollution and long-term ecological risks.
