Swiss Chemicals Ordinance (or ChemO)

As a non member of the EU or the European Economic Area (EEA), Switzerland has its own chemical regulations, the Swiss Chemicals Ordinance on Protection against Dangerous Substances and Preparations, also called ChemO, originally published in 2005.

On June 5th 2015, Switzerland published a revised ordinance (SR 813.11) that implements classification, labeling and packaging (CLP) and REACH-like registration requirements for new substances placed on the Swiss market.


Definition of a “new substance”:

  • A substance with an EC number beginning with 4 (European List of Notified Chemical Substances (ELINCS);
  • A substance with an EC number 6, 7, 8 or 9 (for intermediates), unless the manufacturer can prove that the identity corresponds to a substance listed in the European Inventory of Existing Commercial Chemical Substances (EINECS).
The ExxonMobil fluids, plasticizers and chemical intermediates commercialized in Switzerland correspond to substances listed in EINECS. They therefore do not have to be notified under ChemO and are not impacted by the revised ordinance.

From 1 July 2015, all new substances imported to or manufactured for the first time in Switzerland in quantities greater than 1 ton/year/legal entity (LE) must be:

  • Notified, following the same process as the notification process under EU REACH;
  • Registered, according to the same process as the CLP registration under EU REACH; and/or
  • Declared, as per the same product and process orientated research and development (PPORD) process under EU REACH

The notifier (manufacturer, importer or sole representative) must have his/her usual residence, registered office or subsidiary in Switzerland.

The information presented is not legal advice, is not to be acted on as such and is subject to change without notice. For more information, please contact your ExxonMobil sales representative.
