The Convention prohibits the production and use of PFOS and its related chemicals except in certain applications or as intermediate in the production of chemicals used in these applications. Producer and/or users of PFOS have to register with the Secretariat of the Convention and should take into account guidance on BAT and BEP. They were encouraged by the Conference of the Parties to implement recommendations on risk reduction for PFOS, its salts and PFOS-F that relate to the different stages in the life cycle of PFOS and processes and materials containing PFOS. This guidance (March 2021) has been developed to guide producers and users in adequately addressing the risks of perfluorooctane sulfonic acid (PFOS) and its related substances.

Main target audience is staff responsible for developing management plans for the application of BAT and BEP for the production and use of PFOS and technical staff involved in their implementation.
