Of all the external policies located in the Union’s ‘middle layers’, the Common Commercial Policy (CCP) stands out with flying colours. Here, we encounter one of the oldest fields of external competence, already present in the original EEC Treaty, and also one of the broadest. Moreover, the CCP has given rise to a colourful and highly dynamic jurisprudence, which spurred the development of principles that have become of relevance for other fields of external competence as well. In this chapter, we will first touch upon some general aspects, among which the rationale, general objectives and institutional embedding of the CCP (para. 4.2). Next, we engage in a study of the policy’s exact scope and purview (para. 4.3). Hereafter, we look at the interplay between the CCP and international trade rules (para. 4.4). Finally, we discuss some of the trade policies enacted under the CCP, with particular emphasis on EU anti-dumping rules (para. 4.5).
