A substance of very high concern (SVHC) is a chemical substance
Chemical substance
In chemistry, a chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e. without breaking chemical bonds. They can be solids, liquids or gases.Chemical substances are...

 be subject to authorisation under the REACH Regulation. Indeed, listing of a substance as an SVHC by the European Chemicals Agency
European Chemicals Agency
The European Chemicals Agency is an agency of the European Union which manages the technical, scientific and administrative aspects of the Registration, Evaluation, Authorisation and Restriction of Chemicals system...

 (ECHA) is the first step in the procedure for authorisation and restriction of use of a chemical. The first list of SVHCs was published on 28 October 2008 and updated on 13 January 2010.

Criteria

The criteria are given in article 57 of the REACH Regulation. A substance may be proposed as an SVHC if it meets one or more of the following criteria:
  • it is carcinogen
    Carcinogen
    A carcinogen is any substance, radionuclide, or radiation that is an agent directly involved in causing cancer. This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes...

    ic;
  • it is mutagen
    Mutagen
    In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations cause cancer, mutagens are therefore also likely to be carcinogens...

    ic;
  • it is toxic for reproduction
    Reproductive toxicity
    Reproductive toxicity is a hazard associated with some chemical substances, that they will interfere in some way with normal reproduction. It includes adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring...

    ;
  • it is persistent
    Persistent organic pollutant
    thumb|right|275px|State parties to the Stockholm Convention on Persistent Organic PollutantsPersistent organic pollutants are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes...

    , bioaccumulative
    Bioaccumulation
    Bioaccumulation refers to the accumulation of substances, such as pesticides, or other organic chemicals in an organism. Bioaccumulation occurs when an organism absorbs a toxic substance at a rate greater than that at which the substance is lost...

     and toxic according to the criteria set out in Annex XIII to the REACH Regulation (PBT substances);
  • it is very persistent and very bioaccumulative according to the criteria set out in Annex XIII to the REACH Regulation (vPvB substances);
  • there is "scientific evidence of probable serious effects to human health or the environment which give rise to an equivalent level of concern"; such substances are identified on a case-by-case basis.


Simply because a substance meets one or more of the criteria does not necessarily mean that it will be proposed as an SVHC. Many such substances are already subject to restrictions on their use within the European Union, such as those in Annex XVII of the REACH Regulation. SVHCs are substances for which the current restrictions on use (where these exist) might be insufficient. There are three priority groups for assessment:
  • PBT substances and vPvB substances;
  • substances which are widely dispersed during use;
  • substances which are used in large quantities.

Procedure for listing

Proposals for inclusion of a substance on the list of SVHCs can come either from the European Commission
European Commission
The European Commission is the executive body of the European Union. The body is responsible for proposing legislation, implementing decisions, upholding the Union's treaties and the general day-to-day running of the Union....

 or one of the Member States of the European Union. The proposals are made public by the European Chemicals Agency
European Chemicals Agency
The European Chemicals Agency is an agency of the European Union which manages the technical, scientific and administrative aspects of the Registration, Evaluation, Authorisation and Restriction of Chemicals system...

 (ECHA) and are open for public comment for 60–90 days. If the substance is deemed to meet one or more of the criteria, it is then listed as an SVHC.

Once a substance has been listed as an SVHC, the Agency commissions a technical report from one or more national or private laboratories, which analyses the available information on manufacture, imports, uses and releases of the substance, as well as possible alternatives. On the basis of this technical report, the Agency decides whether to prioritise the substance, in effect, whether to make a recommendation to the European Commission to add the substance to Annex XIV of the REACH Regulation, making its use subject to authorisation. The draft recommendations must be made public and opened for comment for three months before the final recommendations are sent to the Commission. The first draft recommendations were published on 14 January 2009, and new draft recommendations must be issued at least once every two years.

Consequences of listing

The list of SVHCs is primarily a public list of substances for which the European Chemicals Agency is considering imposing a requirement for authorisation for some or all uses. However, there are some direct consequences of including a substance on the list of SVHCs. Suppliers of pure SVHCs must provide their customers with a safety data sheet (SDS). Suppliers of mixtures of substances which contain more than 0.1% by weight of any SVHC must provide their customers with a safety data sheet on request. Manufacturers or importers of articles containing more than 0.1% by weight of any SVHC must provide their customers, and consumers on request, with adequate information on the safe use and disposal of the article, including the name of the SVHC(s) concerned. From 1 June 2011, manufacturers and importers of articles will also have to notify the European Chemicals Agency of the quantities of SVHCs used in their articles.

Candidate list of substances of very high concern

The following substances are included on the candidate list of substance of very high concern. This list is updated at regular intervals by the European Chemicals Agency (ECHA), with the first substances listed on 28 October 2008.

This list is referred to as the "candidate" list because all substances placed on it are candidates for inclusion in Annex XIV of REACH. If a substance is added to Annex XIV, it is given a "latest application date" and a "sunset date". The sunset date is the date after which the substance cannot be used or imported into the EU without authorisation from the ECHA, and the latest application date is the date by which any applications for use must be submitted to the ECHA.

  • The CAS numbers for groups of compounds such as "SCCP" are indicative. Such groups can include several compounds, each of which has a different CAS number.
  • PBT = persistent, bioaccumulative and toxic
  • vPvB = very persistent and very bioaccumulative
