UFI & PCN Notification for Türkiye | Poison Centre Notification
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 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. 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 4,000 notifications.

Frequently Asked Questions

Poison centre notification for Türkiye
Hazardous mixtures placed on the Turkish market require a UFI code and a poison centre notification. We generate the code, build the dossier, submit it and make sure the code appears correctly on the label so that emergency responders can identify the formulation immediately.
What we prepare
- Full composition with concentration ranges
- Classification and label elements
- Toxicological information and first response measures
- Packaging data and product category
- UFI generation and label placement guidance
Who carries the duty
The obligation sits with the company placing the mixture on the market: importer, formulator or a distributor who relabels. Where the manufacturer is abroad, the notification runs through the entity established in Türkiye, and it is worth agreeing in writing who does what.
Updates and reformulation
Any change in composition, classification or packaging requires an updated notification and usually a new UFI. Reformulations that reach the market before the notification is updated are a common and avoidable finding.
