All countries offer the possibility to ask for supplementary information. Notable improvements can be observed across areas such as the publication of user manuals, the provision of a dedicated page for professional users (e.g companies), and the publication in advance of trade-related regulations. There is significant variation across the sample as regards the existence of online means for providing feedback to Customs and of full-time hotlines for asking questions to Customs. The user-friendliness of Customs websites varies as much as in 2010, with a limited set of countries providing sufficient relevant information through the “search” function for selected keywords.
