CE Marking
The letters CE appear on many products that are sold in the European Economic Area (EEA) and is the manufacturers indication of compliance with EU legislation, thereby allowing the free movement of such products within the EEA.
The CE marking is the manufacturer declaring that the product conforms with EU safety, health or environmental requirements and they are confirming the product is valid for sale within the EEA. Since the UK's withdrawal from the EU, most products which required the CE marking would instead require a UKCA marking, although the validity of CE markings was still valid until 1st January 2022.
“This does not apply to existing stock, for example if your good was fully manufactured, CE marked and ready to place on the market before 1 January 2021. In these cases, your good can still be sold in Great Britain with a CE marking even if covered by a certificate of conformity issued by a UK body before 1 January 2021.
