In recent months, the European Commission has adopted implementing acts on the approval of active substances in biocidal products.
This means that an authorization date has been set for each substance and we are approaching the date when the dossier for the authorization of the biocidal products containing this substance must be submitted.

If you wish to continue to market or use a currently notified biocidal product that contains only one active substance that is to be approved, you must submit an application for authorisation no later than the date of authorisation of the active substance. However, if your biocidal product contains more than one active substance, you must submit the application no later than the date of authorisation of the last active substance for that product type.
You can read more about authorization procedures here.
Despite the seemingly distant date, you need to act today because preparing a comprehensive dossier takes time. If you have any questions or need advice, please feel free to contact us and we will be happy to help.
