The Biocidal Products Regulation (BPR) (EU/528/2012) was adopted in 2012 and came into effect on 1st September 2013. The BPR aims to improve the functioning of the internal market through the harmonisation of the rules on the making available on the market and the use of biocidal products, while ensuring a high level of protection of both human and animal health and the environment. 

The BPR replaced the Biocidal Products Directive (BPD) 98/8/EC previously in force since 2000. More information on the BPR is available on the European Chemicals Agency (ECHA) website
