UFI & PCN Notification for Türkiye | Poison Centre Notification
This page describes support from Turkey for mixtures placed on the EU/EEA market. CLP Annex VIII covers in-scope mixtures classified for health or physical hazards, subject to exemptions. Selling solely in Turkey does not by itself create an EU PCN obligation. The relevant EU/EEA duty holder and the target markets must be identified before submission. ECHA — PCN / CLP Annex VIII.
Hazardous mixtures placed on the EU/EEA market require a UFI (Unique Formula Identifier) code and a PCN (Poison Centre Notification). ONAY Mühendislik generates UFI codes and submits PCN notifications on behalf of foreign manufacturers, with 4,000+ notifications completed.
What are UFI and PCN?
The UFI is a 16-character code that links a mixture to its composition and must appear on the label of hazardous mixtures. The PCN provides poison centres with the information needed for emergency health response. The requirement depends on the hazard classification, use and exemptions in EU CLP Annex VIII.
How ONAY manages UFI/PCN
ONAY determines classification, generates UFI codes, prepares the notification dossier and submits it, keeping it consistent with your SDS and label — across more than 4,000 notifications.

Who carries the duty
The applicable duty depends on the operator’s role under CLP. EU/EEA importers and downstream users must assess the notification requirements for their in-scope mixtures; distributors must also check the obligations applicable to their supply activities. Where the manufacturer is abroad, the notification runs through the responsible entity established in the EU/EEA, and it is worth agreeing in writing who does what.
Updates and reformulation
Changes must be assessed against the update rules in CLP Annex VIII. A packaging or trade-name change does not automatically require a new UFI; composition changes must be checked against the applicable criteria. Reformulations that reach the market before the notification is updated are a common and avoidable finding.
