REACH: The EU's Chemical Safety Framework

The EU's big chemical lawExplain▾

If CLP is how the EU labels chemical hazards, REACH is how it manages chemicals across their entire life in the market. REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals, and it is one of the most comprehensive chemical laws in the world.

'No data, no market'Explain▾

REACH flips a familiar burden. Rather than requiring regulators to prove a chemical is dangerous before acting, it puts the responsibility on industry to demonstrate that chemicals can be used safely. Its guiding principle is often summarized as "no data, no market": a company generally cannot manufacture or sell a chemical in the EU unless it has registered it, along with data on its hazards and safe use.

This front-loads safety information into the system, so hazards — including carcinogenicity — are documented before products reach people.

The four steps in the nameExplain▾

REACH's name maps to its four functions:

• Registration. Companies register the chemicals they make or import above certain volumes, submitting hazard and safe-use data.
• Evaluation. ECHA and member states review registrations and can request more information or testing.
• Authorisation. The most concerning substances are placed on a list requiring special permission to use — pushing companies toward safer alternatives.
• Restriction. The EU can impose limits or outright bans on making, selling, or using specific substances.

How REACH handles carcinogensExplain▾

Carcinogens get special attention. A carcinogen (often already classified under CLP) can be identified as a Substance of Very High Concern (SVHC) and placed on the candidate list. From there it can move to:

• The Authorisation List (Annex XIV), meaning companies need EU permission — with a deadline (a "sunset date") after which use is banned unless authorised.
• A restriction under Annex XVII, capping or banning specific uses across the EU.

This gives the EU a genuine mechanism to phase out the most concerning carcinogens over time, steadily pushing industry toward safer substitutes. (See Substances of Very High Concern for how this works in detail.)

Why this reflects the EU's philosophyExplain▾

REACH embodies the EU's precautionary, hazard-aware approach. By requiring data up front and enabling phase-outs based on intrinsic hazard, it can act on carcinogens without waiting for a complete real-world risk tally for every use. That's a notable contrast with the more risk-based US system.

The bottom lineExplain▾

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 — including carcinogens — with the power to phase them out. Administered by ECHA, it's the engine behind much of the EU's control over cancer-causing substances.
