Article 95 and Letters of Access

Access to non-member companies wishing to become substance suppliers under the BPR can be obtained in one of two ways: 

  1. An active substance supplier may join the full IIAHC and the BPR Subcommittee. Membership in the IIAHC is limited to manufacturers of the active substance only. A member of the full IIAHC is a part owner of the IIAHC database and may participate in all IIAHC activities.

  2. An active substance supplier may join only the BPR Subcommittee without joining the full IIAHC. Companies joining only the BPR Subcommittee will be part owners of the BPR dossiers but will not be part owners of the studies referred to in the dossier. The cost to join the BPR Subcommittee includes citation fees. 

Product Registrations under National Authorisations

Companies needing National Authorisations for biocidal products before the active substances have been approved under BPR may require a letter of access to the submitted BPD dossier(s), if the national authority wishes to review the submitted dossier(s). Letters of access to allow review of the BPD dossiers for National Authorisations must be obtained from the IIAHC, not from individual members.

Product Registrations under BPR

A biocidal product cannot be registered under the BPR until the active substance has been approved. Once an active substance has been approved, corresponding product authorisations under BPR can be submitted to any EC member state or to ECHA. Companies wishing to cite the IIAHC dossiers for product authorisations under the BPR must obtain a letter of access from the IIAHC or a member of the BPR Subcommittee.

Study Data for Product Authorisation

The IIAHC will undertake some testing on generic biocidal products for use in BPR product authorisations. In addition, the validated analytical methods for determination of the active substance concentration will be made freely available to formulators. In addition the analytical methods that were used as part of the IIAHC’s 5-batch analysis will be provided to customers of BPR Subcommittee members for their use in conducting the required stability studies on their own products.  Each customer will need to have each of the methods validated at the individual lab performing the stability study.  For additional information and to obtain a copy of these analytical methods, customers can contact the respective BPR Subcommittee member or the IIAHC directly.
