What Are PCN and UFI — And Why Do They Matter?
If you manufacture or import chemical mixtures in the European Union, you're required to meet strict safety and notification regulations under the CLP Regulation (Classification, Labelling and Packaging). Two crucial components of this framework are the Poison Centre Notification (PCN) and the Unique Formula Identifier (UFI). Understanding these requirements is essential to keep your products legally compliant and ensure safety in case of exposure incidents.
What is a PCN?
The Poison Centre Notification (PCN) is a mandatory submission that provides detailed information about hazardous mixtures to the European Chemicals Agency (ECHA). The PCN includes:
- Product name and trade names
- Hazard classification
- Mixture composition
- Packaging details
- Toxicological information
This data allows EU poison centres to respond quickly and effectively during emergency medical calls involving chemical exposure.
What is a UFI?
The Unique Formula Identifier (UFI) is a 16-character alphanumeric code that uniquely identifies a chemical mixture. This code must appear both on the product label and in the PCN submission. It enables poison centres to link a product with its exact formulation, allowing for precise and fast medical guidance.
You can generate a UFI using your company’s VAT number and an internal mixture formulation number. The UFI generator is available free of charge via ECHA's tools.
CLP Label Requirements
Under the CLP Regulation, labels for hazardous mixtures must include:
- Product name or identifier
- Hazard pictograms
- Signal words (e.g., “Danger” or “Warning”)
- Hazard statements
- Precautionary statements
- Supplier contact details
- UFI code
Accurate labelling helps both end-users and emergency responders understand the risks and safety precautions associated with your product.
What is a Safety Data Sheet (SDS)?
A Safety Data Sheet (SDS) provides essential information about a substance or mixture. It covers physical and chemical properties, health and safety measures, storage and transport requirements, and emergency procedures. An SDS is vital for both professional users and regulators and is required for all hazardous mixtures.
Who Needs to Comply?
These requirements apply to:
- Manufacturers of chemical mixtures
- Importers of products into the EU
- Downstream users who rebrand or reformulate mixtures
Consumer and professional use mixtures have been subject to UFI and PCN rules since 2021, and mixtures for industrial use must comply as of 2024. All existing products on the market must meet the requirements by January 1, 2025.
