Northern Ireland follows the EU Cosmetics Regulation (EC) No 1223/2009 for cosmetics placed on its market, so the EU notification portal (CPNP) applies for Northern Ireland.

Northern Ireland can feel confusing because it is part of the United Kingdom, but for many product rules (including cosmetics), it works like the EU. This is why people sometimes say Northern Ireland has a “dual” system.

1) The simple map: Great Britain vs Northern Ireland

To understand compliance, start with a map. The UK has two different rule paths for cosmetics:

This “two-lane” setup is the reason people talk about a “dual” situation: one part of the UK (NI) follows EU product rules for cosmetics, while the other part (GB) follows the UK system.

2) What does “dual statute” mean in real life?

When people say “dual statute,” they usually mean this practical reality:

• One company can have two legal compliance tracks for the same product line—one track for NI (EU rules) and one track for GB (UK rules).
• Two portals may be needed if you sell in both places: CPNP (for NI) and SCPN (for GB).
• Ingredient rules can diverge over time because EU annex changes and UK changes do not always happen in the same way or at the same time.

3) Which portal do I use: CPNP, SCPN, or both?

Case A — You sell only in Northern Ireland (and/or EU/EEA)

If the product is placed on the Northern Ireland market, the notification is handled through the EU Cosmetics Product Notification Portal (CPNP). This is because NI cosmetics placement follows the EU cosmetics framework for goods, so the EU portal is the matching notification tool.

Case B — You sell in Northern Ireland and in Great Britain

If you sell the same cosmetic product in Northern Ireland and also in Great Britain, you usually need:

• CPNP notification for the NI market, and
• SCPN notification for the GB market.

That is why some businesses end up doing “both” notifications: it is not because NI uses two portals, but because the business sells into two different markets (NI and GB) with two different notification systems.

4) Responsible Person: where must they be for Northern Ireland?

A “Responsible Person” (RP) is the official person or company that holds the product file and is legally responsible for the cosmetic on the market. For Northern Ireland, because the system follows the EU cosmetics framework, the RP setup follows the EU-style requirements used for NI placement.

In practice, this often means:

• For a product placed on the Northern Ireland market, you need an RP that fits the NI/EU-aligned requirements (commonly: NI-based or EEA-based in the compliance model).
• For a product placed on the Great Britain market, you need a UK/GB-aligned approach and use SCPN.

This is one of the biggest “real-world” compliance differences, because it affects who can legally act as the RP for the specific market.

5) TPO in Northern Ireland: allowed or banned, and when?

TPO is not allowed in cosmetic products placed on the Northern Ireland market from 1 September 2025.

Why? Because Northern Ireland follows the EU cosmetics rules for goods, and the EU set a ban date for TPO (Trimethylbenzoyl Diphenylphosphine Oxide) in cosmetics. So the EU date is the date that matters for NI placement.

If you run a nail gel webshop, this is important because TPO was commonly used as a photoinitiator in nail gel systems. From the NI perspective, any product with TPO is “not compliant for NI placement” after that EU date.

6) Silver in Northern Ireland: allowed or not, and when do the new rules start?

Silver is not a single simple yes/no answer. The rules depend on which silver ingredient you mean and how it is used.

The EU introduced a major update for silver rules in cosmetics that applies from 1 May 2026. Because Northern Ireland follows EU cosmetics rules for goods, this update also becomes the rule for Northern Ireland placement starting that date.

Here is the practical way to handle “silver” questions in a safe compliance process:

1. Identify the exact ingredient name (INCI) used on the cosmetic label or in the formula (for example: “Silver,” “Silver (nano),” “Colloidal Silver,” or a CI colorant reference if relevant).
2. Check the Annex status under the EU Cosmetics Regulation annexes (and specifically the updated rule set applying from 1 May 2026).
3. Match the product type and use: nail gel colorant use is not the same as antimicrobial claims, oral products, or nano-material use.

So, if someone asks, “Is silver still allowed in Northern Ireland?” the correct answer is:

“It depends on the silver ingredient form and use; the updated EU restrictions apply from 1 May 2026, and some forms are restricted or prohibited while others may still be allowed under conditions.”

7) What you should do if you sell cosmetics into Northern Ireland

If you want an easy checklist, use this one:

• Step 1 — Decide your market: Are you selling in NI only, GB only, or both?
• Step 2 — Use the right portal:
  • NI: CPNP
  • GB: SCPN
  • Both markets: typically both portals
• Step 3 — Check substance dates for NI using EU dates:
  • TPO: banned from 1 September 2025 (NI follows EU rule)
  • Silver updates: apply from 1 May 2026 (NI follows EU rule)
• Step 4 — Confirm RP readiness: Make sure the Responsible Person setup matches the market (NI/EU-aligned for NI placement).
• Step 5 — Keep evidence: Maintain the Product Information File (PIF), safety assessment, and supporting documents in a way that matches the legal market you place the product on.

8) The final takeaway

Northern Ireland is part of the UK, but for cosmetics it follows the EU cosmetics rulebook for goods. This is why NI uses the EU notification portal (CPNP) and why EU substance dates (like the TPO ban date) matter for NI. If you also sell in Great Britain, you add a second compliance track using the UK portal (SCPN). For TPO, the key NI date is 1 September 2025. For silver, the key NI change date is 1 May 2026, and whether silver is allowed depends on the exact type of silver ingredient and its use.
