This article examines how product surveillance actors operate in the EU’s network structure, with a focus on forms of cooperation. Specifically, the study explores coordination systems adopted in market surveillance to demonstrate the network structure’s suitability for implementing the European Union’s policy on product safety assurance. The paper aims to demonstrate that in the context of the rapidly evolving e-commerce industry and the rise in cross-border sales of goods to the EU, market surveillance is ensured through a legal framework that involves cooperation between surveillance authorities and economic operators at both the national and EU level, within a network structure. The effectiveness and efficiency of this approach is established through the coordination of actions and sharing of information among the entities involved.
