Poison Centre Notifications (PCNs) are a key requirement for companies placing chemical mixtures on the EU market. Required under Annex VIII of the CLP Regulation, PCNs ensure that emergency health services have the information needed to respond effectively in case of exposure to hazardous mixtures.
While the obligations are clear, many companies struggle with timely and accurate submission, leading to delays or rejections by national poison centres. Understanding common pitfalls can help organisations streamline compliance and avoid regulatory headaches.
What Are Poison Centre Notifications?
A PCN provides essential information about a hazardous mixture, including:
These notifications are submitted via national portals, often using a standardised format linked to Unique Formula Identifiers (UFIs), which allow poison centres to quickly identify the exact mixture in case of an emergency call.
Common Mistakes That Delay Acceptance
Despite clear guidelines, submissions often encounter delays. The most frequent issues include:
1. Incorrect or Missing UFIs
The Unique Formula Identifier is a core element of any PCN. A missing, incorrect, or improperly formatted UFI will typically result in rejection or requests for resubmission.
2. Incomplete Ingredient Information
Providing partial or inconsistent information about hazardous components, concentrations, or CAS numbers can prevent the poison centre from fully assessing the product.
3. Outdated or Inconsistent SDS Data
Poison centres expect data to align with your Safety Data Sheet (SDS). Discrepancies between SDS composition and PCN submissions are a common cause of delays.
4. Misunderstanding Thresholds
Companies sometimes fail to recognise concentration thresholds for hazardous substances that trigger notification requirements. This can result in missing a PCN entirely or submitting it too late.
5. Non-compliance with National Formats
While EU regulations provide a harmonised framework, submission portals vary by member state. Using incorrect templates, languages, or units of measurement can delay acceptance.
6. Last-Minute Submissions
Submitting notifications at the last moment without adequate internal review or quality checks increases the likelihood of errors and rejections.
Best Practices for Smooth Submission
To ensure your PCNs are accepted without delay:
Why Early Preparation Matters
Proactive management of PCNs not only avoids regulatory delays but also strengthens supply chain confidence and market access. Companies that integrate PCN preparation into product stewardship processes are less likely to face last-minute compliance crises.
At Penman Consulting, we guide companies through every stage of PCN preparation, from data collection to submission, ensuring that notifications comply with Annex VIII and are accepted the first time.
