Chemicals industry: prepare for after the transition period

The UK has left the EU but remains strongly committed to the effective and safe management of chemicals. Guidance on regulating chemicals after the transition period is available:

End of UK transition period (from January 2021)


From 1 January 2021 applications to make biocidal active substances and products available on the UK market must be submitted to HSE. How HSE will process these applications is currently being finalised.


Businesses will also need to make sure they are fully informed about their obligations and duties under the classification, labelling and packaging regulation for chemicals.
