The short answer
REACH is the EU's overarching chemical law. It requires companies to register chemicals and their hazards, lets the EU restrict or require authorisation for the most concerning substances, and can phase out carcinogens. Its motto: 'no data, no market.'
REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals.
Companies must register chemicals and provide hazard and safety data.
The principle is 'no data, no market' — unregistered chemicals can't be sold.
The most concerning substances face authorisation or restriction.

The full explanation.
The EU's big chemical law
If CLP is how the EU labels chemical hazards, REACH is how it manages chemicals across their whole life in the market. REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals. It is one of the most far-reaching chemical laws in the world.
'No data, no market'
REACH flips a familiar burden. Regulators do not have to prove a chemical is dangerous before they act. Instead, industry has to show that chemicals can be used safely. The guiding principle is often summed up as "no data, no market." A company generally cannot make or sell a chemical in the EU unless it has registered it, with data on its hazards and safe use.
This front-loads safety information into the system. Hazards — including the power to cause cancer — are on record before products reach people.
The four steps in the name
REACH's name maps to its four jobs.
- Registration. Companies register chemicals they make or import above set volumes, with hazard and safe-use data.
- Evaluation. ECHA and member states review registrations. They can ask for more information or testing.
- Authorisation. The most concerning substances go on a list that requires special permission to use. That pushes companies toward safer options.
- Restriction. The EU can set limits or outright bans on making, selling, or using a substance.
How REACH handles carcinogens
Carcinogens get special attention. A carcinogen is often already classified under CLP. It can then be named a Substance of Very High Concern (SVHC) and put on the candidate list. From there it can move to:
- The Authorisation List (Annex XIV). Companies then need EU permission, and there is a deadline — a "sunset date" — after which use is banned unless authorised.
- A restriction under Annex XVII, which caps or bans specific uses across the EU.
This gives the EU a real way to phase out the most concerning carcinogens over time. It also pushes industry toward safer substitutes. (See Substances of Very High Concern for the detail.)
Why this reflects the EU's philosophy
REACH shows the EU's precautionary, hazard-aware approach. It asks for data up front and allows phase-outs based on the hazard itself. So it can act on carcinogens without waiting for a full real-world risk tally for every use. That is a sharp contrast with the more risk-based US system.
The bottom line
REACH is the EU's overarching chemical framework. It registers chemicals and their hazards, evaluates them, and can authorise or restrict the most concerning ones, carcinogens included. It can also phase them out. Run by ECHA, it is the engine behind much of the EU's control over cancer-causing substances.

Common questions
What is REACH?
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the EU's main law governing chemicals. It requires companies to register the chemicals they make or import, along with data on hazards and safe use.
What does 'no data, no market' mean?
Under REACH, a company generally cannot sell a chemical in the EU unless it has been registered with the required safety data. The burden is on industry to show chemicals can be used safely.
How does REACH control carcinogens?
Carcinogens can be identified as Substances of Very High Concern, placed on a candidate list, and then subjected to authorisation (needing special permission to use) or restriction (limits or outright bans).
Who runs REACH?
The European Chemicals Agency (ECHA) administers REACH, working with the European Commission and member states.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
