EU - ECHA Published a Guidance for Identification and Naming of Substances under REACH and CLP Regulation

​ECHA published a guidance regarding the identification and naming of substances under REACH and CLP Regulation in December 2023.

This document describes how to name and identify a substance under REACH and CLP. It is part of a series of guidance documents that are aimed to help all stakeholders with their preparation for fulfilling their obligations under the REACH and CLP Regulations. These documents cover detailed guidance for a range of essential REACH and CLP processes as well as for some specific scientific and/or technical methods that industry or authorities need to make use of under REACH and CLP. 

The objective of this guidance document is to give guidance for manufacturers and importers on recording and reporting the identity of a substance within the context of REACH and CLP. As an important key element of substance identification the guidance document provides guidance on how to name the substance. It also gives guidance on whether substances may be regarded as the same in the context of REACH and CLP and how the “one substance, one registration” (OSOR) principle can be implemented by defining the Substance identity profile” (SIP). Identifying the same substances which can be covered by the same SIP is important for inquiries, for data sharing, for Joint Submission of data, for notification to the Classification and Labelling inventory and for harmonization of Classification and Labelling. ​
