The CH Mark is Switzerland’s official conformity marking for certain product categories following the country’s independent technical regulations. After Switzerland's bilateral mutual recognition agreements with the EU were partially revised, the CH mark became mandatory for specific regulated products placed on the Swiss market starting from August 2022 (for some categories).

This mark serves as a Swiss equivalent to the CE mark, confirming that products comply with applicable Swiss safety, EMC, and environmental regulations.
