The UKCA (UK Conformity Assessed) certificate is a new requirement for PPE goods sold in the United Kingdom (Wales and Scotland) and must bear the UKCA marking, which takes effect on January 1, 2021. During the transition period, however, you can continue to use the CE marking in most cases until December 31, 2021. Northern Ireland faces a unique set of challenges. EU conformity markings will be used to comply with EU regulations as long as the Northern Ireland Protocol is in effect. However, if you use a UK-based Notified Body to perform mandatory third-party conformity assessment, a UKNI (United Kingdom Northern Ireland) marking must also be applied.
