ABSTRACT
This chapter examines three sub-cases related to the customs security measures that emerged in the EU–US political and security agenda: the Container Security Initiative (CSI), the Mutual Recognition Decision, and the 100 per cent scanning rule. It shows that in both Europe and the US before the 9/11 attacks the security aspects of customs functions and international supply chains were not pronounced, and therefore there was no attempt to establish a regime. Apart from transatlantic security, the chapter explains sub-cases of the economic and relationship of the EU and the US. It also examines how customs security was conceptualised before and after the 9/11 attacks. After 9/11 the perceptions of the two sides regarding the role of customs changed; the new security environment, together with a new set of perceived threats, prompted the EU and the US to give an anti-terrorist mission and role to customs with the security aspect of customs functions being heavily emphasised.
