The global database on Non-Tariff Measures


Developed by WTO
Adapted for TRAINS data by UNCTAD



Non-Tariff Measure data collection for TPP countries

The Trans-Pacific Partnership (TPP) agreement, concluded in October 2015 between Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States and Vietnam, covers a broad range of trade- and investment-related issues. Among those are non-tariff measures (NTMs), which are covered in several chapters of the agreement.

UNCTAD and the World Bank collect NTM data in a joint project for all 12 TPP countries. Data works for TPP countries have been financially supported by Canada, GRIPS, Japan and the United States. The National Graduate Institute for Policy Studies (GRIPS) is an international premier policy school with the aim of contributing to the betterment of democratic governance around the world. Financial support has been coordinated by the Global EPAs Research Consortium (secretariat at GRIPS). Financial support is gratefully acknowledged.


The objective of the project is to contribute to close the transparency gap and to support TPP negotiators and researchers to better understand the implications of TPP.


In a first phase NTM data are collected and updated using a standardized approach following the International Classification of NTM and the UNCTAD Guidelines to Collect Data on Official NTMs.

The data is available on the TRAINS NTMs data platform at i-tip.unctad.org as well as on the World Integrated Trade Solution (WITS) data platform at wits.worldbank.org.

In a second phase ad valorem equivalents for NTMs will be calculated jointly by the World Bank and UNCTAD.



UNCTAD is the focal point within the United Nations system for the integrated treatment of trade and development. UNCTAD’s Programme on NTMs aims to enhance the transparency on NTMs and to provide support to policy makers.
