Welcome to the LOA (Lower Olefins and Aromatics) REACH Consortium website

This website is intended to provide some general information on the Consortium, its objectives and scope, the substances which were registered in 2010, costs of letters of access for those substances and instructions on how to join any of the SIEFs currently managed by the LOA REACH Consortium.

Classification and Labelling of LOA Substances

Classification, Labelling and Packaging regulation - CLP-Regulation (EC) No 1272/2008
Enterprise and Industry Guidance Page - DG Enterprise
ECHA Guidance on CLP - ECHA CLP Page

Classification and Labelling positions have been agreed within the Consortium and the SIEF for all substances managed by LOA and have been registered with ECHA by the lead registrant.

To promote consistency of use, links to the agreed CLP position are provided below. They can be found on the ECHA dissemination page which displays the lead registrant’s dossier.

Please note that these CLP positions are relevant for the substances as registered by the Lead Registrant. Anyone using them must satisfy themselves that the substance they classify does not have a different purity profile that may require a different CLP position. This is critical for the UVCB streams where more than one possible classification is given dependent upon the known composition of the specific stream.
