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.

Letters of Access

Letters of Access – Prices for 1st January 2014 to 1st January 2018

Ahead of the 2010 REACH deadline the LOA REACH Consortium submitted dossiers for 120 Lower Olefin and Aromatic substances in 12 categories.

In February 2014 the LOA REACH Consortium provided costs for letters of access below 100 tpa to reflect the reduced information requirements.

The costs of a letter access are detailed below. Please note that a letter of access is required for each legal entity using the registration materials - affiliates are not covered by a single letter of access.

Prices for LOA REACH Consortium Letters of Access (Monoconstituents)

The following prices are valid until 1st January 2018, after which an additional €1,000 will be charged per letter of access regardless of the tonnage band selected.

Prices for LOA REACH Consortium Letters of Access (Categories)

As part of the process of developing the registration dossiers for a number of streams and UVCB substances, LOA assigned them to categories based on the chemical and technological descriptors of each substance. During the assessment phase there was a check of the compositional coherency of the streams within the category, which formed the basis of the LOA Category Justification Documents.

You can find descriptions of the LOA Categories and links to the Category Justification Documents here
