The UKNI marking is a specific conformity mark for products placed on the market in Northern Ireland (NI). It is not a standalone mark; it 必须 always accompany an EU conformity marking, such as the CE标志如果产品需要强制性第三方合格评定，且该评定由英国机构进行，则必须提交此文件。此文件旨在向监管机构表明这一事实。
UKNI标记，有时也称为UK(NI)标记，是北爱尔兰议定书的一项独特成果。它的存在是必要的，因为尽管北爱尔兰仍是英国关税区的一部分，但它遵循欧盟的货物法规，以避免与爱尔兰共和国出现硬边界。这就造成了双重市场局面。
A product sold in Northern Ireland must bear the CE标志. If a manufacturer chooses to use a conformity assessment body based in the EU to conduct a mandatory third-party assessment, only the CE mark is needed. However, if the manufacturer uses a body based in the United Kingdom (i.e., in Great Britain) for that same assessment, the product must be marked with both the CE mark and the UKNI mark. The UKNI mark essentially signifies that the CE compliance has been verified by a UK body. Products bearing the CE and UKNI marking can be sold in Northern Ireland but cannot be sold in the EU/EEA, as EU authorities do not recognise assessments from UK-based bodies.
