In Annex I of the Directive 98/8/EC, implemented via the Decreto Legislativo n. 174 of the 25th of February 2000, all the active substances are listed which, after a careful evaluation at European level, have been considered as suitable for the preparation of biocidal products.

Important information is reported in this list, such as the date of inclusion of the active substance (which corresponds to the date of revocation of the PMC authorisation, and also to the deadline within which the companies have to submit the marketing authorisation application as a biocidal product) and the relative numbers of the European and National Journals, reporting the decree of inclusion.

It is important to note that the inscription of an active substance in Annex I does not allow for the use of the substance for any type of use but is tied to the specific PTs. This is shown in the Annex I, where for each active substance the PT of interest is highlighted.
