The establishment of global value chains requires changes in the approach to market surveillance. Intermediate inputs have become an important part of the world trade, particularly as they are increasingly being sourced through imports rather than domestic production. The nature of internal markets combined with the effects of the global supply chain makes it increasingly necessary to adopt a truly coordinated approach to market surveillance. Market surveillance practices among the European Union Member States and worldwide differ by each country. Within the European Union it is the responsibility of each individual Member State, which has different resources, priorities and legislative framework, to develop and sustain their internal market surveillance. Different countries around the world develop their own standardization arrangements and start to produce more products that only conform to their own safety standards. The aim of this chapter is to analyse approaches to market surveillance through different product groups, in order to evaluate the differences between the sectors and countries.
