2025 21 The product assessment shall pay particular attention to 
the exposures, the risks and the efficacy linked to any uses covered by an application for authorisation, but not addressed in the Union level risk assessment of the active substance. 
For biocidal products, author isations are subject to the 
following conditions: 
(1) Products containing copper pyrithione shall not 
be authorised for and used by non-professional 
users. 
(2) For industrial or professional users, safe 
operational procedures and appropriate 
organisational measures shall be established. 
Where exposure cannot be reduced to an 
acceptable level by other means, products shall 
be used with appropriate personal protective 
equipment. 
(3) Labels and, where provided, instructions for use 
                                                            
1 The purity indicated in this column was the minimum degree of purity of the active substance used for the evaluation made in a ccordance with Article 8 of 
Regulation (EU) No 528/2012. The active substance in the product placed on the market can be of equal or different purity if it  has been proven technically 
equivalent with the evaluated active substance. 
2 For the implementation of the common principles of Annex VI to Regulation (EU) No 528/2012, the content and conclusions of ass essment reports are available

shall indicate that children shall be kept away 
until treated surfaces are dry. 
(4) Labels and, where provided, safety data sheets of 
products authorised shall indicate that 
application, maintenance and repair activities 
shall be conducted within a contained area and 
on impermeable hard standing with bunding to 
prevent direct losses and minimise emissions to 
the environment, and that any losses or waste containing copper pyrithione shall be collected 
for reuse or disposal. 
(5) For products that may lead to residues in food or 
feed, the need to set new or to amend existing 
maximum residue levels (MRLs) in accordance

European Parliament and of the Council
