UKCA is short for UK Conformity Assessed. On February 2, 2019, the British government announced that it will adopt the UKCA labeling scheme in the absence of a Brexit agreement. After March 29, trade with the United Kingdom will be conducted in accordance with the rules of the World Trade Organization (WTO). The UKCA mark is the same as the CE mark. The manufacturer is responsible for ensuring that the product complies with the standards stipulated by the law, and after making a self-declaration in accordance with the prescribed procedures, the corresponding mark is made on the product.

The UK is currently in a transitional period for Brexit, which will end at the end of 2020. On September 1, 2020, the Department of Business, Energy and Industrial Strategy of the United Kingdom officially announced on its official website that the UKCA logo will be used from January 1, 2021.

At present, most of the products covered by the CE mark will also belong to the scope of use of the UKCA mark. It will also be suitable for aerosol products.

From January 1, 2021, those products that require the CE mark in the EU market must have the UKCA mark, manufacturer's declaration of conformity, and complete conformity assessment technical documents to enter the UK market. The requirements of the UKCA Declaration of Conformity DoC are also equivalent to the EU CE Marking Declaration of Conformity, but it is necessary to use the corresponding British BS standard on the DoC and declare compliance with UK regulations.

As a transitional period, products with the same technical requirements and marking rules of the UK and EU can still accept the CE marking before January 1, 2022. However, if there is a change in the CE marking rules of the product during this period, the CE marking made under the new EU rules will not be accepted by the UK market. Therefore, it is recommended to transition to the use of the UKCA logo as soon as possible.
