Product standards and CE marking for the Northern Ireland market

How product standards and marking requirements differ for the Northern Ireland market under the Windsor Framework. Covers CE marking requirements, why UKCA marking is not valid in NI, the EU General Product Safety Regulation applying in NI from December 2024, and dual compliance obligations for businesses selling across the whole UK.

Northern Ireland
Guide summary

Use CE marking for products sold in Northern Ireland, not UKCA marking. If you sell across the UK, CE marking works for both. From December 2024, follow EU safety rules for NI.

  • CE marking required for Northern Ireland market
  • UKCA marking not valid in Northern Ireland
  • UKNI marking needed with CE if UK body assessed product
  • CE marking accepted in Great Britain indefinitely
  • EU safety rules apply in NI from December 2024
  • Label GB-standard goods in NI as ‘Not for EU’
  • Full ‘Not for EU’ labelling required by 1 July 2025
  • Check if your product needs third-party assessment
  • Keep records of conformity assessments
  • Use EU Notified Body if selling to EU and NI

If you manufacture, import, or sell products in Northern Ireland, you face a fundamentally different regulatory landscape from the rest of the United Kingdom. Under the Windsor Framework, Northern Ireland follows EU product regulations for goods, while Great Britain (England, Scotland, and Wales) has its own regime. This means different marking requirements, different safety regulations, and, for businesses operating UK-wide, the need for dual compliance.

The practical consequence is straightforward but important: products placed on the Northern Ireland market must carry CE marking, not UKCA marking. If you currently sell products only in Great Britain using UKCA marking, those products cannot be sold in Northern Ireland without CE marking. Conversely, CE marked products can be sold in both NI and, under indefinite recognition arrangements, in Great Britain.

This guide explains how the dual regime works, what it means for your product marking and compliance strategy, and how the EU General Product Safety Regulation introduces additional obligations for the NI market.

CE marking in Northern Ireland: the core requirement

For products covered by EU harmonised regulations (which includes most manufactured consumer and industrial products), CE marking is mandatory for the Northern Ireland market. This is not optional and is not subject to any transitional period. The requirement has applied since the end of the Brexit transition period on 1 January 2021, continued under the Northern Ireland Protocol, and is now governed by the Windsor Framework.

CE marking on a product means it has been assessed against the relevant EU directive or regulation and meets all applicable requirements for safety, health, and environmental protection. The conformity assessment may be carried out by:

  • The manufacturer (self-declaration), where the relevant directive permits this for lower-risk products
  • An EU Notified Body, where third-party assessment is required
  • A UK Approved Body, in which case the product must also carry the UK(NI) marking alongside the CE marking

The UK(NI) marking

The UK(NI) marking is a supplementary marking used when a UK-based body (a UK Approved Body) has carried out the conformity assessment for a product intended for the Northern Ireland market. It must appear alongside the CE marking, never on its own.

Key points about the UK(NI) marking:

  • It is required only when a UK Approved Body conducted the mandatory third-party conformity assessment
  • It must always accompany CE marking, not replace it
  • Products bearing the UK(NI) marking cannot be placed on the EU market. The UK(NI) mark is not recognised in EU member states
  • If you want to sell the same product in both NI and the EU, use an EU Notified Body for conformity assessment so you can use CE marking alone

Why UKCA marking does not work in Northern Ireland

The UKCA (UK Conformity Assessed) marking was introduced on 1 January 2021 as the GB-only replacement for CE marking. It demonstrates compliance with GB-specific product regulations. However, because Northern Ireland follows EU product rules under the Windsor Framework, UKCA marking alone is not valid for products placed on the NI market.

This catches businesses that have switched from CE to UKCA marking for their GB sales. If those businesses also sell into Northern Ireland, they need to maintain CE compliance or they cannot legally place products on the NI market.

For many businesses, the simplest strategy is to maintain CE marking for all UK sales. Since October 2024, CE marking has been recognised indefinitely in Great Britain alongside UKCA. This means a single CE marked product can be sold across the entire UK, whereas a UKCA-only product is limited to Great Britain.

Dual compliance for UK-wide businesses

If you sell products across the whole United Kingdom, you have two options:

Option 1: CE marking for everything (recommended for most businesses)

Maintain CE marking compliance. CE marked products are accepted in Northern Ireland (as required) and in Great Britain (under indefinite recognition). This is the simplest approach and avoids the need for dual product lines.

Option 2: Dual marking

Products can carry both CE and UKCA markings simultaneously if they meet the requirements of both EU and GB regulations. This may be necessary if EU and GB standards diverge in future, but currently the requirements are substantially identical for most product categories.

For most SMEs, Option 1 (CE marking for all UK sales) is the pragmatic choice. It requires only one conformity assessment process, one set of technical documentation, and one product marking.

EU General Product Safety Regulation in Northern Ireland

From 13 December 2024, the EU General Product Safety Regulation (Regulation 2023/988) applies in Northern Ireland, replacing the UK General Product Safety Regulations 2005 for the NI market. The GB GPSR 2005 continues to apply in Great Britain.

The EU GPSR introduces requirements that go beyond the GB regime:

  • Online marketplace obligations: Online marketplaces have specific duties to prevent dangerous products being listed, including cooperation with enforcement authorities and single points of contact
  • Enhanced traceability: Stricter requirements for identifying and tracing products through the supply chain
  • Risk assessment: Updated criteria for assessing product safety, reflecting modern risks including connected products and cybersecurity
  • Economic operator responsibilities: Clearer duties for manufacturers, importers, distributors, and fulfilment service providers

For businesses selling into both GB and NI, this means complying with two different general product safety regimes. Products already placed on the NI market before 13 December 2024 under the old rules do not need to be relabelled, but new products must comply with EU Regulation 2023/988.

Sector-specific considerations

The dual regime has particular implications for certain sectors:

  • Medical devices: CE marking is accepted in GB until 30 June 2028 (general devices) or 30 June 2030 (IVDs). NI requires CE marking permanently. The MHRA regulates in GB; EU rules apply in NI.
  • Construction products: CE marking is accepted indefinitely in both GB and NI. This is one area where the regimes are effectively aligned.
  • Electrical and electronic products: EMC, low voltage, and radio equipment directives apply in NI as EU law. GB has equivalent but separate regulations.
  • Toys: EU Toy Safety Directive applies in NI. GB has its own toy safety regulations, but CE marking is accepted.

What this means for your business

If you sell products only in Great Britain, you can use either CE or UKCA marking. If you sell products in Northern Ireland, you must use CE marking. If you sell UK-wide, CE marking covers both markets and is the simplest compliance path.

Before making a product marking decision, consider:

  • Do you currently sell into Northern Ireland or plan to?
  • Do you export to the EU or plan to? (CE marking is required for EU export)
  • Has your conformity assessment been carried out by an EU Notified Body or a UK Approved Body?
  • Are your products subject to sector-specific rules with different timelines?

For specific product marking queries, contact the Office for Product Safety and Standards (OPSS), which can advise on both GB and NI requirements.
