Hazardous mixtures placed on the Turkish 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 2,000+ 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. Both are mandatory for hazardous mixtures under Türkiye's chemical legislation.
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 2,000 notifications.
