The Secretariat also conducted a verification of the information received through the questionnaire against publicly available information and other existing reports. The 2014 update allowed including in the database eight additional OECD countries (Austria, Chile, Estonia, Finland, Ireland, Israel, Luxembourg and Slovenia). The 2014 average includes the additional OECD countries covered by the database, however the observed changes are mainly attributable to the evolution of trade facilitation in the OECD countries initially covered in 2010-11 and not to the expansion of country coverage.11 Overall, the most significant improvements can be observed for appeal procedures, simplification and harmonization of documents, streamlining of procedures, as well as internal and external border agency cooperation. As regards advance rulings, automation, and governance and impartiality small improvements can also be noted, while for indicators such as information availability, involvement of the trade community, and fees and charges there is no evolution or even a slight regression.
