The expression " local products " is often used to refer to a large variety of trust mechanisms, which are usually divided into two main types, depending on whether they operate by using a specific label or by developing a solid reputation via the building of proximity relationships. Based on the results of several case studies on qualification devices in France and Italy, this essay identifies intermediary structures that do not smoothly fit with any of the two precedent categories. As European societies are struggling under the weight of a widespread crisis, which is mostly exacerbated by profound changes in their territorial institutions, such networks appear as key drivers of resilience. However, their durability is not to be taken for granted. This essay tries to explore their conditions of sustainability.
