Despite EU regulatory harmonisation and the principle of mutual recognition, onTariff Measures in cross-border trade of agri-food products often violate the EU acquis on the free movement of goods. This paper assesses the pervasiveness and main features of these measures in intra-EU trade of the agri-food sector between 1961 and 2002. It also focuses on procedural and enforcement issues related to how EU member states solve the infringement proceedings opened by the EU Commission to remove agri-food TMs. The study is based on a unique large dataset on compliance with EU law and provides a comprehensive sector-specific assessment of TMs in intra-EU trade.
