Data Dissemination

UNCTAD’s NTM data is made publicly available through two portals, TRAINS and WITS. NTMs have been collected from official sources, mainly national laws and regulations.

 

  1. Trade Analysis Information System (TRAINS)

    TRAINS portal is a one-stop-shop for traders, policymakers, and researchers to acquire comparable information on trade regulations and NTMs from across the world. It allows public users to benefit from efficient search queries, generation of visualized charts, easy data retrieval, as well as download customized search results.

     

  2. World Integrated Trade Solution (WITS)

    WITS integrates TRAINS with other trade-related databases, such as UN COMTRADE, WTO Integrated Data Base (IDB) and WTO Consolidated Tariff Schedules (CTS). As a result, WITS offers an interface that provides access to databases covering imports, exports and protection data — tariff and non-tariff measures — over time. Users may obtain detailed data for individual countries. They may also create their own country and product aggregation. The registration is free.

 

NTMs are classified according to the International Classification of NTMs, as established by the MAST group.

Products are classified at the most detailed level according to the Harmonized System (HS) classification or at the national tariff line level.
