UKNI marking
The product was put on the Northern Ireland market after a mandatory third-party conformity assessment by a notified body based in the UK. It accompanies the CE marking.
A mark tells you what the maker declares, never that the product is safe.
- What it looks like
- The letters UK above the letters NI, set as a square block, always next to a CE marking.
- Who may apply it
- The manufacturer adds it when it has used a UK-based Northern Ireland notified body for a conformity assessment that the law makes compulsory. Products that are self-declared carry CE alone.
What it does not promise
It never stands on its own: without the CE marking beside it, it has no meaning. It says which kind of body did the assessment. It is not a separate safety certificate, and it does not apply in the Crown dependencies (Guernsey, Jersey, the Isle of Man) or the British Overseas Territories.
