The International Trade Centre (ITC) is currently collecting survey data on NTMs in more than 30 developing countries. In each country, a firm level survey with 150 to 1,000 phone screening and up to 300 face-to-face interviews is carried out in order to identify, at the product level, those measures that exporting companies perceive as barriers in their daily business. After giving an overview over the process of data collection, we will present some of the main findings, and point out directions for future usage of the data, including policy advisory and research.
