The Use of UFI Codes in Chemicals: Safety and Management

The Unique Formula Identifier (UFI) Code and Its Importance

The Unique Formula Identifier (UFI) code is a unique identification code used to ensure the safety of chemical mixtures and enable swift responses during emergencies. This 16-character alphanumeric code has been made mandatory under European Union regulations, especially for hazardous chemicals.

What is a UFI Code?

Each UFI is specifically created for a chemical mixture and is directly associated with its composition. It appears on product labels or Safety Data Sheets (SDS). Through the UFI code, poison control centers and medical professionals can quickly identify the composition of a product in emergencies, facilitating accurate treatment. For this purpose, a poison center notification (PCN) file must be prepared.

How is it Generated?

UFI codes are generated using a free online tool provided by the European Chemicals Agency (ECHA). The process considers the company’s VAT number and the unique identity of the mixture when creating the code.

Why is it Important?

UFI codes help minimize the impacts of adverse situations that may arise during the transport, storage, and use of toxic or hazardous products. Additionally, they simplify regulatory compliance and enhance transparency in the supply chain.

Regulations and Transition Periods

The use of UFI codes became mandatory for consumer and professional products as of January 1, 2021. For industrial products, this requirement has been extended until January 1, 2024 (Note: The text just says 2024, the precise date is Jan 1, 2024). This transition period allows manufacturers and importers the necessary time to comply.


In conclusion, the use of UFI codes in chemicals is a critical step toward managing chemical safety and protecting public health. It contributes to building a reliable chemical safety system for both manufacturers and consumers. This initiative plays an essential role in ensuring safer working and living environments for the future.
