It is primarily the responsibility of the users of substances and preparations to check in a timely manner (i.e. before the relevant expiration date of the application),
- whether the uses of substances of Annex 1.17 ORRChem cannot be substituted by other substances or alternative processes before the expiry of the transitional period, and
- whether a use in Switzerland corresponds to a use in the EU of the substance for which an authorisation has been requested or granted in the EU or
- whether an application for a temporary exemption for the further use in Switzerland must be submitted to the Notification Authority for Chemicals.
According to Art. 13 ORRChem the cantons are responsible for monitoring compliance with the provisions of this Ordinance in the absence of regulations to the contrary. Consequently, the cantons are responsible for checking whether substances of Annex 1.17 ORRChem are used according to the provisions of this Annex. Manufacturers and cantonal authorities should address their questions to the Notification Authority for Chemicals, which shall give an opinion in consultation with the assessment authorities.
