UNCTAD TRAINS database can be used freely by policy makers, researchers and businesses provided that the data are not put up for sale or otherwise commercially exploited, and that the database is acknowledged as the source (UNCTAD TRAINS database). Users of the database are not allowed to disseminate the data or parts of the database in other dissemination tools unless written permission is given by the Chief of UNCTAD's Trade Information Section, Trade Analysis Branch.


The content on this website is provided "as is" for information purposes only and does not constitute any advice, judgment, or opinion whatsoever by the United Nations, its partner organizations, or entities. The data in TRAINS are collected from official sources (see NTMs Data User Guide), but not provided or verified by member states. Neither the data are collected from the official notifications. The identification of non-tariff measures (NTMs), classification thereof, and designation of particular codes represent the views of the data collectors and does not necessarily reflect the views of the United Nations, any of its partner organizations, or any of its member states.

Data on contingent trade-protective measures (chapter D) stem from the World Trade Organization notifications and the World Bank's Anti-dumping database; however, neither of the two mentioned organizations was directly involved in any data collection or classification. The data in TRAINS on chapter D are merged and processed by UNCTAD and are not the responsibility of the World Trade Organization or the World Bank.

UNCTAD strives for the highest level of accuracy and is committed to promptly correcting any errors on its part. All efforts have been made to construct a comprehensive high quality NTMs database to enhance transparency and support policy makers. However, as NTMs data collection is an extremely challenging task, UNCTAD does not guarantee the absolute comprehensiveness, accuracy, reliability, correctness, fitness for use for a particular purpose, or otherwise, whatsoever, of the data.

The designations employed and the presentation of the material on the website do not imply the expression of any opinion whatsoever on the part of the secretariat of the United Nations concerning the legal status of any country, territory, city or area, or of its authorities, or concerning the delimitation of its frontiers or boundaries.
