Ordinance
on Protection against Dangerous Substances and Preparations
(Chemicals Ordinance, ChemO)

¹ If a man­u­fac­turer places a pre­par­a­tion on the mar­ket which is clas­si­fied as dan­ger­ous be­cause of the phys­ic­al or health haz­ards it poses, the man­u­fac­turer must la­bel the pre­par­a­tion with a unique for­mula iden­ti­fi­er (UFI).

² He must gen­er­ate the UFI us­ing the elec­tron­ic sys­tem provided by the No­ti­fic­a­tion Au­thor­ity. Gen­er­at­ing the UFI us­ing the elec­tron­ic sys­tem is not re­quired if the pre­par­a­tion already has a UFI that has been gen­er­ated on the basis of the CLP Reg­u­la­tion⁶⁰.

³ The UFI, pre­ceded by the ac­ronym "UFI:" in cap­it­al let­ters, must be prin­ted or af­fixed in a clearly vis­ible, legible and in­delible man­ner in the fol­low­ing loc­a­tion:

a.

on the la­bel in the sec­tion for sup­ple­ment­al in­form­a­tion in ac­cord­ance with Art­icle 2525 of the CLP Reg­u­la­tion; or

b.

on the in­ner pack­aging to­geth­er with the oth­er la­bel ele­ments; if the in­ner pack­aging is of such a nature or so small that the UFI can­not be prin­ted or af­fixed there­on, it may be prin­ted or af­fixed with the oth­er la­bel ele­ments on the out­er pack­aging.

⁴ In the case of pre­par­a­tion that are not pack­aged, the UFI must be in­dic­ated on the safety data sheet or, in the case of sup­ply to private users, in a copy of the la­bel ele­ments in ac­cord­ance with Art­icle 29 para­graph 3 of the CLP Reg­u­la­tion, to­geth­er with the oth­er la­bel ele­ments.

⁵ Para­graphs 1–4 do not ap­ply if the pre­par­a­tion is not sub­ject to the ob­lig­a­tion to no­ti­fy in ac­cord­ance with Art­icle 54.
