The written communication is an important prerequisite for the placing on the market of the old biocidal product during the authorisation procedure. Therefore information according to § 13 (1) No 1 and 4 of the Act on Biocidal Products and according to Annex IIB section I and X and, if applicable according to Annex IVB Section I and X of the Biocidal Products Directive are necessary. In case of a registration procedure information according to § 14 (1) No 1 and § 9 (2) No 1 to 3 and 6 to 7 of the Act on Biocidal Products.
