What Is ECHA? The European Chemicals Agency

The European Chemicals Agency, or ECHA, is a decentralised agency of the European Union. It sits in Helsinki, Finland, at Telakkakatu 6. It was established in 2007. It employs about 600 people. Its director is Sharon McGuinness.

Its job is narrow and deep. ECHA does not regulate food, medicines, or air quality. It regulates chemicals as chemicals, across four bodies of EU law.

ECHA exists because of one article in one regulation. That article is Article 75(1) of Regulation (EC) No 1907/2006, known as REACH. It states that a European Chemicals Agency is established. Its stated purpose is to manage, and in some cases carry out, the technical, scientific and administrative parts of the Regulation. Its other stated purpose is to keep those parts consistent across the Union.

Article 76 then sets out what ECHA is made of, starting with a Management Board. The design is deliberate. The agency handles science and administration. Legal decisions to ban or restrict a substance are taken elsewhere.

ECHA runs four EU regulations:

• REACH. Registration, Evaluation, Authorisation and Restriction of Chemicals.
• CLP. Classification, Labelling and Packaging. This is Regulation (EC) No 1272/2008.
• BPR. The Biocidal Products Regulation.
• PIC. The Prior Informed Consent Regulation. It covers exports of hazardous chemicals.

For cancer, the two that matter are REACH and CLP.

REACH works on a simple principle: no data, no market. The trigger is volume.

A company must register with ECHA if it makes or imports a substance at 1 tonne or more per year. What the registration must contain scales with the amount:

• At 1 tonne or more per year, the information listed in Annex VII.
• At 10 tonnes or more per year, Annexes VII and VIII.

Higher tonnages pull in further annexes. The result is a single Union database of chemical hazard data, built by companies at their own cost. Our page on REACH covers the registration machinery in more detail.

This is the part that matters for cancer, and it runs on named articles.

Article 57 lists the properties that can put a substance on the road to authorisation. Six categories qualify:

• Carcinogenic, category 1 or 2.
• Mutagenic, category 1 or 2.
• Toxic for reproduction, category 1 or 2.
• Persistent, bioaccumulative and toxic, under Annex XIII.
• Very persistent and very bioaccumulative, under Annex XIII.
• Equivalent concern. This covers substances with scientific evidence of probable serious effects. They are named case by case. Endocrine disruptors are the example given in the text.

Substances identified under Article 59 go onto the Candidate List of Substances of Very High Concern. Candidate listing is not a ban. It is the trigger for legal duties.

Article 58 covers what happens next. If a substance is added to Annex XIV, the decision must set a sunset date. After that date, placing the substance on the market and using it are prohibited unless an authorisation has been granted. The decision must also set an application deadline at least 18 months before the sunset date, so companies that need the substance have a fixed window to make their case.

One provision is worth knowing because it applies to ordinary shoppers.

Under Article 33, any supplier of an article containing a Candidate List substance above 0.1% by weight must give the recipient enough information for safe use. At minimum, that means naming the substance.

The second paragraph goes further. On request from a consumer, the supplier must provide the same information, free of charge, within 45 days.

That is a legal right with a deadline attached, and it exists whether or not the product carries a warning label.

CLP sets the hazard classes that appear on the label. For carcinogenicity there are two categories, split into three levels:

• Category 1A. Known human carcinogen. The judgment rests largely on human evidence.
• Category 1B. Presumed human carcinogen. The judgment rests largely on animal evidence.
• Category 2. Suspected human carcinogen. The human or animal evidence is not strong enough for 1A or 1B.

Each level comes with a fixed hazard statement and a fixed signal word:

• Category 1A and 1B carry H350: May cause cancer, with the signal word Danger.
• Category 2 carries H351: Suspected of causing cancer, with the signal word Warning.
• Where a route is proven to be the only one that causes the hazard, the statement names it. H350i reads "May cause cancer by inhalation."

Here is the practical difference between the EU system and an advisory body. An IARC classification is scientific advice. A CLP classification is law. It changes what must be printed on a drum, a bottle, or a safety data sheet across the Union.

ECHA prepares the technical case. It does not, by itself, ban a chemical.

Adding a substance to the authorisation list is an EU procedure. So is imposing a restriction. Both involve the European Commission and the member states, with ECHA's scientific input. That split is the point. Evidence is gathered in one place. The political decision is taken in another.

ECHA does three other things. It works with the Commission and national governments to spot substances of concern. It runs a free public database of chemical information. And it helps companies work out what the law asks of them.

A chemical made anywhere must meet these rules to be sold into the EU. That gives the Candidate List and Annex XIV reach past the Union's borders. It is why one EU decision can pull a substance out of consumer goods worldwide.

Trying to work out what a carcinogen listing means for you? Start with what a carcinogen is. Then read hazard versus risk.
