区域国家：英国

变更类型：UKCA

英国退欧后，在英国市场销售的产品必须要符合UKCA标识的管控。

UKCA是英国合格认定（UK Conformity Assessed）的简称。

UKCA标志和CE一样，都是由制造商负责确保产品符合法令规定的标准，并按照规定程序进行自我声明后，在产品上做相应的标识。

制造商可以寻求有资质的第三方实验室来测试产品的性能，以证明产品符合相关标准。并出具符合性声明VOC/AOC，由此为基础出具制造商的自我声明DOC。DOC上需包含制造商名称和地址，产品型号等关键性的参数信息。

从2021年1月1日起，UKCA将取代欧盟的CE认证，绝大多少产品将纳入UKCA认证管控范围。

英国本土认证机构UKCA NB机构在NANDO数据库（Notified and Designated Organisations），4位数的NB编号不变。由英国UKCA NB机构发放NB证书。

官方原文：

Check whether you need to use the new UKCA marking

Selling goods in Great Britain

The UKCA marking applies to most goods previously subject to the CE marking. It also applies to aerosol products that previously required the ‘reverse epsilon’ marking.

The technical requirements (‘essential requirements’) you must meet – and the conformity assessment processes and standards that can be used to demonstrate conformity – are largely the same as they were for the CE marking.

The circumstances in which you can use self-declaration of conformity for UKCA marking are the same as for CE marking. Check the list of areas where self-declaration is permitted.

The UKCA marking came into effect on 1 January 2021. However, to allow businesses time to adjust to the new requirements, you will still be able to use the CE marking until 1 January 2022 in most cases.

In some cases, you need to apply the new UKCA marking to goods being sold in Great Britain immediately from 1 January 2021.

The CE marking is only valid in Great Britain for areas where GB and EU rules remain the same. If the EU changes its rules and you CE mark your product on the basis of those new rules you will not be able to use the CE marking to sell in Great Britain, even before 31 December 2021.
