Background information and explanations
Before accessing the database, users are asked to familiarize themselves with the information provided on the different outputs the database can generate. Users are particularly advised to consult the page explaining the TIV Tables before using the TIV data generated by the database.
The database is revised and updated every spring. As part of this process, changes will be made to information previously contained in trade registers and TIV tables. For this reason, information extracted from a previous version of the database, or contained in previous editions of the SIPRI Yearbook, could have changed. We therefore advise users of the arms transfers database to always use the latest version. All information from the database must be used in accordance with the 'terms and conditions of use'.
Both the size of the database and the difficulty of obtaining reliable information on arms transfers can result in errors. We welcome users alerting us to any errors and to any publicly available sources containing information that may improve the content of the database. Lastly, we welcome suggestions for improved database service from users, if you have any questions or comments, please contact the Arms Transfers Programme.
