SDS Studio™Definition: The UFI is a 16-character alphanumeric code, generated from the company VAT number (or an ECHA company key) and a formulation number, that links a hazardous mixture's label to its poison centre notification.
The UFI must be printed on the label, preceded by the letters UFI, and where it is given in the SDS, it belongs in subsection 1.1 (Regulation (EU) 2020/878).
A new UFI is needed whenever the composition changes beyond the allowed variation.
Legal anchor: CLP Annex VIII, Part A, point 5. Permitted composition variations are set in Part B, point 3.4.
