As products used by the general public may be marketed throughout Switzerland, the label must be written in at least two official languages. The hazard and safety statements are grouped together according to the language.
Chemical products that are placed on the market under the Cassis de Dijon principle may also be labelled only in the language of the sales region in question. This requires that steps be taken to ensure that no sales occur in other linguistic regions. The sale of such products in officially bilingual municipalities such as Biel/Bienne or Fribourg/Freiburg is not possible.
