WITS vs TRAINS
WITS is a software application which is designed to integrate several trade-related databases and provide easy access
TRAINS is one of the four major databases currently accessible through WITS
![Page 3: Using WITS with UNCTAD TRAINS Trade Analysis and Information System For the DATA Day at WTO Geneva, May 18-19 2009](https://reader036.vdocument.in/reader036/viewer/2022062618/551504c75503465e608b464e/html5/thumbnails/3.jpg)
Databases of WITS
• TRAINS (UNCTAD)
• COMTRADE (UN Statistics Division)
• Integrated Database (IDB-WTO)
• Consolidated Tariff Schedule (CTS-WTO)

Data Accessibility
• COMTRADE: Free access to International Organizations, others against a fee
• TRAINS: Access to governments and international and regional organizations, as well as to donors to TRAINS Trust Fund
• WTO: Access to WTO member governments and selected international organizations

Data contents of TRAINS (as of 1 May 2009)
• Tariff measures at national tariff line level for 165 countries (over 1000 country/years since 1988), including preferential rates such as RTA and GSP in many cases
Primary data are drawn from

Advanced Query
Users construct queries comprising of:
– Reporter countries – Products – Partner countries – Years
![Page 9: Using WITS with UNCTAD TRAINS Trade Analysis and Information System For the DATA Day at WTO Geneva, May 18-19 2009](https://reader036.vdocument.in/reader036/viewer/2022062618/551504c75503465e608b464e/html5/thumbnails/9.jpg)
Advanced Query – Parameters
Reporter Countries– Individual countries or user-
defined groups of countriesProducts– Individual products or user-
defined aggregates of products in various product classifications (HS, SITC,ISIC, etc)

Assumptions:
– Each product is independent– A same product from different supplier is
an imperfect substitute– Three sets of elasticties (Demand,
Supply and Substitution between two suppliers)
