Registrant's guide : how to act in substance evaluation : February 2018

Practical Guides aim to help duty holders to fulfil their obligations in relation to the REACH Regulation (or "REACH"). They provide practical tips and advice and explain ECHA's processes and scientific approaches. Practical Guides are produced by ECHA, under its sole responsibility. They do not replace the formal Guidance (which is established under the formal guidance consultation process involving stakeholders) that provides the principles and interpretations needed for a thorough understanding of the requirements of REACH. However, they explain, in a practical way, specific issues presented in the formal Guidance. ECHA invites interested parties to submit experiences and examples to be incorporated in future updates of this document. These can be submitted using the contact form. The purpose of this practical guide is to explain in simple terms what substance evaluation (SEv) is, and how substances are selected and subsequently evaluated. This guide aims also to highlight the opportunities as well as the obligations that you, as registrant, have in providing the information requested under substance evaluation. This guide describes (i) what kind of different administrative outcomes you can expect from the substance evaluation process and (ii) how and when you can react to communications received from an evaluating Member State competent authority (eMSCA) and/or from ECHA. This guide also addresses data sharing and communication between registrants of the same substance.
