Definition
The UFI, or unique formula identifier, is a 16-character code that links a mixture to its poison centre notification.
Art. 25(7) and Annex VIII Part A, section 5 CLP
Legal term: unique formula identifier
Explained
The unique formula identifier (UFI) has sixteen characters and appears on the label after the prefix "UFI:". It links the product with the information submitted to the appointed bodies, usually poison centres, under Annex VIII of the CLP Regulation. In an emergency the staff of a poison centre can find the composition quickly. The last transitional deadline for these submissions ended on 1 January 2025. Since Annex II of REACH was amended by Regulation (EU) 2020/878, the UFI also belongs in section 1.1 of the safety data sheet where one exists. If the composition changes, a new UFI can be needed, and then label, submission and safety data sheet change together.
