Unique formula identifier
From Wikipedia, the free encyclopedia
The unique formula identifier (UFI) is a code printed on products with hazardous mixtures in the European Economic Area (EEA), meant to help calls to poison control centers to determine the contents.
The UFI is mandated in the European Economic Area for consumer, professional and industrial products containing hazardous mixtures.[1] Use in new consumer products started on 1 January 2021 and will be required for industrial products on 1 January 2024. From 1 January 2025, existing products must include the UFI.[2] The UFI is controlled by the European Chemicals Agency (ECHA).
The UFI takes the form of a prefix acronym UFI:, followed by a 16-digit alphanumeric code, separated in 4 blocks with dashes. All letters are upper case and letters that are hard to discern from numerals are omitted. The UFI contains a checksum.[3] A UFI (with prefix) looks like:
UFI: N1QV-R02N-J00M-WQD5
The UFI must be printed on the packaging where it is easy to find, near the hazard label elements or bar code, or if it is an unpackaged product, on the safety data sheet.[2]
