Few things in EU compliance cause as much head-scratching as two four-letter acronyms that look almost interchangeable yet answer to completely different laws. If you have ever puzzled over PCN vs CPNP — which one your product actually needs, whether they are the same thing, or whether you are supposed to do both — you are in very good company. Cosmetic brand owners, importers and distributors trip over this constantly, usually because the names sound alike and both involve “notifying” something before a product goes on sale.
The short answer is that they are not substitutes, and most cosmetics need only one of them. This article explains what each notification is, the separate regulation behind it, how to tell which one applies to your product, and the specific situations where a single business genuinely needs both.
Key takeaways
- CPNP and PCN are separate obligations under separate regulations — one never replaces the other.
- CPNP (Cosmetic Products Notification Portal) is required for every cosmetic under Article 13 of Regulation (EC) No 1223/2009. It is free and produces no UFI.
- PCN (Poison Centre Notification) is required under Annex VIII of the CLP Regulation for hazardous chemical mixtures sold to consumers or professionals. It produces a UFI you must print on the label.
- A normal finished cosmetic needs CPNP only. CLP does not apply to finished cosmetics intended for the final user, so no PCN is triggered.
- You may need both across your range if you also sell non-cosmetic chemical products — cleaners, room sprays, reed diffusers — or a “cosmetic” that is legally a chemical mixture.
- The deciding question is almost always: does the product legally count as a cosmetic?
Same acronym energy, two different rulebooks
The confusion is understandable. Both CPNP and PCN are pre-market notifications, both feed data to poison centres, and both are submitted through an online portal. But they sit under two entirely separate pieces of EU law with different purposes and different duty holders.
CPNP is a cosmetics obligation: the EU Cosmetic Products Regulation requires the Responsible Person to register every cosmetic centrally before it is placed on the market. PCN is a chemicals obligation: the CLP Regulation requires anyone placing a hazardous mixture on the market to give poison centres the formulation details they need in a medical emergency. A finished lipstick and a bottle of drain cleaner live in different legal worlds — CPNP governs the first, PCN the second. Reading them as two flavours of the same task is where brands go wrong.
CPNP: the cosmetic product notification
CPNP stands for the Cosmetic Products Notification Portal, the free electronic system run by the European Commission. Under Article 13 of Regulation (EC) No 1223/2009, the EU Responsible Person must notify each cosmetic here before it is made available anywhere in the EU market — whether or not the product is “hazardous” in any chemical sense. A moisturiser, a mascara, a bar of soap: they all need a CPNP notification.
The notification captures the product category and name, the Responsible Person’s details, the country of first placing, any nanomaterials or CMR substances, the frame formulation (or full formula), and the original labelling artwork. That gives national authorities a market-surveillance record and gives poison centres a first point of reference if someone swallows or reacts to a product. Crucially, CPNP does not generate a UFI and carries no fee.
Note: CPNP is a notification, not an approval — submitting it does not mean an authority has reviewed or “passed” your product, and the legal responsibility for safety stays with you and your safety assessor. If you are new to it, our guides on what CPNP notification is and the step-by-step CPNP submission walk through what you enter.
PCN: the poison centre notification
PCN stands for Poison Centre Notification. It is required under Annex VIII of the CLP Regulation (EC) No 1272/2008 and submitted through ECHA’s Poison Centres portal in a harmonised EU format. The trigger is different in kind: a PCN is needed when a mixture is classified as hazardous for health or physical effects — think corrosive, flammable, acutely toxic — and is placed on the market for consumer or professional use. The duty falls on the company placing that mixture on the market, typically the importer or a downstream user.
The purpose is purely emergency response: if a member of the public or a worker is exposed, poison centres need to know what is in the product to advise treatment fast. That is also why a PCN produces a UFI — a Unique Formula Identifier that links a specific formulation to the notification and, unlike CPNP, must be printed on the label. Our overview of the CLP Regulation, the explainer on what a UFI code is, and the full guide to poison centre notification (PCN) set out the mechanics.
CPNP vs PCN at a glance
Side by side, the two notifications share almost nothing except the word “notification” and a role in protecting public health. Here is the comparison in full.
| Feature | CPNP | PCN |
|---|---|---|
| Legal basis | Article 13, Regulation (EC) No 1223/2009 (EU Cosmetic Products Regulation) | Annex VIII, CLP Regulation (EC) No 1272/2008 |
| Purpose | Register a cosmetic with authorities and poison centres before it is placed on the EU market | Give poison centres formulation data for emergency medical response to hazardous mixtures |
| Who submits | The EU Responsible Person (a distributor too, for certain relabelled products) | The company placing the mixture on the market — usually the importer or downstream user |
| Which products | Every finished cosmetic product, hazardous or not | Mixtures classified as hazardous for health or physical effects, for consumer or professional use |
| Portal | Cosmetic Products Notification Portal, run by the European Commission | ECHA Poison Centres portal (harmonised PCN format) |
| Output / UFI | A notification record; no UFI produced | A Unique Formula Identifier (UFI) that must appear on the label |
| When / deadline | Before the product is placed on the market; kept updated when the formula or label changes | Before the hazardous mixture is placed on the market; the obligation is now fully in force for consumer, professional and industrial uses |
| Cost | Free to submit | Free to submit (costs sit in classification and preparation) |
Do you need both? How to tell
For most cosmetic brands, the honest answer is CPNP yes, PCN no — and one rule unlocks why. The CLP Regulation does not apply to cosmetic products in their finished state intended for the final user. Because Annex VIII sits inside CLP, that exemption means a genuine finished cosmetic does not require a poison centre notification, even if its formula happens to be flammable. An alcohol-based eau de parfum or a cosmetic aerosol carries its flame warning under aerosol and cosmetic rules, not through a PCN. As a cosmetic, it needs CPNP and nothing more here.
So where does the “you might need both” scenario actually come from? Almost always from products that are not cosmetics, or from a brand whose range spills over into chemicals:
- Household and air-care lines — surface cleaners, laundry products, room sprays and reed diffusers are chemical mixtures, not cosmetics. If classified as hazardous and sold to consumers or professionals, they need a PCN with a UFI and do not go through CPNP.
- Borderline products — a “cosmetic” that is really a biocide, medical device or chemical mixture under the law. If it is not legally a cosmetic, CPNP is the wrong route and CLP may apply. Our guide to cosmetic vs medicinal vs biocide is the place to settle it.
- Mixed portfolios — a skincare range (CPNP) sold alongside a scented candle or a cleaning concentrate (PCN). Both obligations then live in one business, applied to different products.
The single most useful test is this: work out first whether each product legally counts as a cosmetic. If it does, you are on the CPNP path. If it does not and it is a hazardous mixture for consumer or professional use, you are on the PCN path. A product almost never runs down both tracks at once — but a company with a varied catalogue easily can. Where a chemical line is involved, our poison centre notification service handles the classification and submission.
Warning: Do not assume a CPNP notification covers your poison-centre obligations, or vice versa. They protect different things and are checked by different authorities. Selling a hazardous cleaning product with no PCN and no UFI on the label — or placing a cosmetic on the market with no CPNP — both expose you to enforcement. National authorities can order withdrawal or recall and impose administrative penalties.
Where the UFI fits in, and the mistakes to avoid
The UFI is the clearest dividing line between the two systems, and the source of a lot of avoidable errors. A UFI is generated only through the PCN process; CPNP never produces one. So if a marketplace, retailer or customer asks for “the UFI code” on a straightforward cosmetic, the answer is usually that a cosmetic does not have one — and that a CPNP reference is not a UFI. Three mistakes come up again and again:
- Expecting CPNP to hand you a UFI. It will not. If your product legitimately needs a UFI, it needs a PCN — which means the product is a hazardous mixture, not a plain cosmetic.
- Treating one notification as the other’s substitute. A completed PCN does not register your cosmetic under the Cosmetics Regulation, and a CPNP entry does not satisfy CLP.
- Forgetting the non-cosmetic side of the range. Brands focus hard on getting cosmetics right and overlook that their candle, diffuser or cleaning add-on is a CLP mixture with its own notification and label duties.
Get the classification right at the start and the rest follows cleanly: cosmetics to CPNP, hazardous mixtures to PCN, and the UFI printed on the labels that actually need it.
Bringing it all together
PCN and CPNP are easy to confuse and impossible to swap. CPNP is the free, universal registration of every cosmetic under the Cosmetic Products Regulation; PCN is the poison-centre notification for hazardous chemical mixtures under CLP, complete with a UFI on the label. A normal finished cosmetic needs CPNP only. You need both across your business only when your range also includes products that are not cosmetics.
If your catalogue is cosmetics and you simply need those products registered correctly and kept up to date, our CPNP notification service takes care of the submission and the ongoing changes — and if part of your range is chemical, we can flag where a PCN and UFI belong too, so nothing falls between the two systems.
Frequently asked questions
Is PCN the same as CPNP?
No. They are separate notifications under separate laws. CPNP is the cosmetic product registration required by Article 13 of Regulation (EC) No 1223/2009, while PCN is the poison centre notification required by Annex VIII of the CLP Regulation for hazardous chemical mixtures. One never replaces the other — see our explainer on what CPNP notification is.
Do cosmetics need a poison centre notification (PCN)?
Generally no. The CLP Regulation does not apply to finished cosmetics intended for the final user, so a genuine cosmetic does not trigger a PCN — even a flammable perfume. It needs a CPNP notification instead. A PCN is required for chemical mixtures that are not cosmetics, such as cleaning products or room sprays classified as hazardous.
Does CPNP give me a UFI code?
No. CPNP produces a notification record but never a UFI. A UFI is generated only through the poison centre notification process under CLP. If someone asks for a UFI on a plain cosmetic, it usually does not have one — read more in our guide to what a UFI code is.
Who is responsible for submitting each notification?
For CPNP, the EU Responsible Person submits the notification for each cosmetic. For PCN, the duty falls on the company that places the hazardous mixture on the market — normally the importer or downstream user. The two roles can sit in the same business but are legally distinct.
How do I tell whether my product needs CPNP or PCN?
Start by deciding whether the product legally counts as a cosmetic. If it is a cosmetic, it goes through CPNP. If it is not a cosmetic but a hazardous mixture for consumer or professional use, it goes through PCN with a UFI. Borderline cases are worth confirming — our guide to cosmetic vs medicinal vs biocide helps you classify it first.
