Waiting for a draft legislation from the French government to define a Geographical Indication (GI) for their soap, the four most important soap factories (including La Savonnerie du Midi) among the ones remaining in the Bouches-du-Rhône, France, decided to ally in 2011 and created the Union of Marseille Soap Professionals (UPSM).
They signed a Quality Charter that guarantees the composition of traditional Marseille soap as well as the process used to manufacture it and its geographical origin. The products scrupulously respecting the specifications defined by this charter, and they alone, display the collective registered brand. This collective registered brand ensures compliance with the specifications of the Union of Marseille Soap Profesionals.
This stamp represent the Union of Marseille Soap Profesionals (UPSM) collective registered brand.
