Letter of Access

A Letter of Access (LoA) is available for a full dossier and for intermediates. You need to purchase a LoA for each affiliate of your company (with an individual registration). If you are interested, please contact us via E-mail SIEF@SDIOConsortium.com.

If you are an ONLY REPRESENTATIVE (OR) you can also use the LOA agreement and state on the first page on whose behalf you are acting. Please note that you will need to purchase a LOA for each company that you represent.

Reimbursement

Based on the REACH guidance on data sharing SDIOC developed a Reimbursement Mechanism Exercise in 2016/2017. The Reimbursement Mechanism Exercise determines the cost/price of each LOA for each individual registrant for each substance.  The Reimbursement Mechanism Exercise takes into account the number of registrants for a substance in a given tonnage band and the initial payment made by each LOA purchaser and SDIOC member. The LOA payment made by each registrant will be taken into account and offset against the actual cost of the individual registration at the moment of reimbursement. Depending on whether the LOA price exceeds or comes within the LoA payment, each SIEF member will receive an invoice or credit note. The reimbursement exercise will be repeated every two years.

Each SIEF member shall continue to benefit from the rights of access to data needed to register the substance/s under REACH as long as relevant invoice(s) are fully paid by relevant deadlines. 

SDIOConsortium continues to review available data and updates the dossiers as required.
