Frequently Asked Questions

Under Article 45 of the CLP Regulation, it is essential for importers and downstream users who place mixtures on the market to notify the appointed bodies in the Member States with specific product information. This notification applies to hazardous mixtures based on their health or physical hazards, as outlined in Annex VIII of the CLP.

So, how do you know if you are required to submit a Poison Centre Notification? Simply follow these steps:

  1. Is your product subject to the CLP regulation?
  2. What is your role in the supply chain? Are you an importer or a downstream user?
  3. Is your product classified as hazardous? For example:
    • Does it pose a health risk (e.g., is it an eye irritant)?
    • Does it have dangerous physical properties (e.g., is it flammable)?

If you can answer “yes” to all of these, submitting a Poison Centre Notification and generating a UFI for your product is a must. There may also be other specific scenarios that require a notification, even if you are not a downstream user—each case should be evaluated individually.

If you’ve determined that your product requires a Poison Centre Notification, you will need to gather the necessary data to complete your notification. The goal of Annex VIII of the CLP Regulation is to standardize the data requirements for Poison Centre Notifications across the entire European Union. This means that with one submission, you can meet the notification requirements for most EU countries—streamlining the process and ensuring compliance across borders.

Here’s a quick rundown of the essential data you’ll need for your PCN:

  • Product composition
  • Product trade name (or trade names if multiple are used)
  • List of countries where the product is being submitted
  • Basic physicochemical properties (e.g., pH value, colour, physical state)
  • Packaging information (how your product is presented on the market)
  • Product use and type
  • Safety Data Sheets (in the required languages)

In some cases—such as for industrial products with a limited submission type—additional or slightly different data may be needed. However, this list covers the core requirements you’ll need to submit your PCN and stay compliant.

The C&L Notification is a requirement under Articles 39 & 40 of the CLP Regulation. Specifically, Article 40 mandates that manufacturers and importers must notify the Classification and Labelling (C&L) Inventory when placing certain substances on the market. This includes:

  • Substances subject to registration, or
  • Substances which meet criteria for classification as hazardous either on their own or in a mixture above the concentration limits specified in the CLP Regulation where relevant, which results in the classification of the mixture as hazardous

If you are an importer or manufacturer of a hazardous substance, you may be obligated to submit a C&L Notification. To help you navigate this, here is a simple cheat sheet to determine your obligations:

  • Hazardous substances placed on the market on their own? You must submit a C&L Notification.
  • Hazardous substances in a mixture that contribute to the hazard classification? You must submit a C&L Notification.
  • Hazardous substances in a mixture, but they do not drive the hazard classification? No C&L Notification required.
  • Substances already REACH Registered? No need for a C&L Notification.
