Reach

Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union Regulation of 18 December 2006. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment. Its 849 pages took seven years to pass, and it has been described as the most complex legislation in the Union's history and the most important in 20 years. It is the strictest law to date regulating chemical substances and will affect industries throughout the world. REACH entered into force in 1 June 2007, with a phased implementation over the next decade.

When REACH is fully in force, it will require all companies manufacturing or importing chemical substances into the European Union in quantities of one tonne or more per year to register these substances with a new European Chemicals Agency (ECHA) in Helsinki, Finland. Because REACH applies to some substances that are contained in objects ('articles' in REACH terminology), any company importing goods into Europe could be affected. About 143,000 chemical substances marketed in the European Union were pre-registered by the 1 December 2008 deadline. Although pre-registering was not mandatory, it allows potential registrants much more time before they have to fully register. Supply of substances to the European market which have not been pre-registered or registered is illegal (known in REACH as "no data, no market").

REACH also addresses the continued use of chemical 'substances of very high concern' (SVHC) because of their potential negative impacts on human health or the environment. From 1 June 2011, the European Chemicals Agency must be notified of the presence of SVHCs in articles if the total quantity used is more than one tonne per year and the SVHC is present at more than 0.1% of the mass of the object. Some uses of SVHCs may be subject to prior authorisation from the European Chemicals Agency, and applicants for authorisation will have to include plans to replace the use of the SVHC with a safer alternative (or, if no safer alternative exists, the applicant must work to find one) - known as 'substitution'. As of March 2009, there are fifteen SVHCs.

REACH applies to all chemicals imported or produced in the EU. The European Chemicals Agency will manage the technical, scientific and administrative aspects of the REACH system.

To somewhat simplify the registration of the 143,000 substances and to limit vertebrate animal testing as far as possible, Substance Information Exchange Forums (SIEFs) are formed amongst legal entities (such as manufacturers, importers, and data holders) who are dealing with the same substance. This allows them to join forces and finances to create 1 registration dossier.
