REACH - Registration, Evaluation and Authorization of Chemicals


REACH is to further improve the protection of human health and the environment through the better and earlier identification of certain chemical substances. The European Union (EU) has adopted regulation no.1907/2006, also known as the REACH (Registration, Evaluation and Authorization of Chemicals) regulation, which became effective 1st June 2007. The EU REACH regulation has been brought into UK law under the European Union (Withdrawal) Act 2018. REACH, and related legislation, have been replicated in the UK with the necessary changes to make it operable in a domestic context. The Key principles of the EU REACH Regulation have been retained. The new Domestic regime within the UK is known as UK REACH. 

To address the requirements of the above REACH regulation, Perception Sensors and Instrumentation Ltd. (PSI) request their supply chain component suppliers to provide information on the relevant chemicals in supplied products. This enables PSI to provide their customers and end users with information about any Substances of Very High Concern (SVHC’s) that are currently on the candidate list in concentrations of greater than 0.1% in a sold product’s homogenous materials weight. PSI REACH data is based upon information provided by their suppliers. 

An up-to-date candidate list can be found on the ECHA website as follows: 


Registration is required for companies that either produce or import into the UK/EU any relevant substance in volumes that exceed one tonne per substance. PSI do not produce SVHC and do not exceed this import amount. PSI are therefore not required to register. 

Please contact us if you require any further information related our products and REACH regulation.
