Trade Registers are written outputs that contain information on deals between specific arms suppliers and recipients over a specific time period that are included in the SIPRI Arms Transfers Database. A deal is only included in a Trade Register if reliable information has been verified that an order has been placed or deliveries have begun.
You can also choose whether to include all deals or only those involving certain types of weapon system, and whether the Trade Register is laid out according to supplier(s) or recipient(s).
In a Trade Register, deals are divided between, on the one hand, those that involve the physical transfer of military equipment and, on the other, those that involve the transfer of technology or provision of a licence, allowing the goods to be produced or assembled by the recipient.

SIPRI statistical data on arms transfers relates to actual deliveries of major conventional
weapons. To permit comparison between the data on such deliveries of different weapons and to identify general trends, SIPRI has developed a unique system to measure the volume of international transfers of major conventional weapons using a common unit, the trend-indicator value (TIV).

SIPRI TIV figures do not represent sales prices for arms transfers.
Examples of SIPRI TIV
To better illustrate how the SIPRI TIV is constructed/calculated, four types of transfer are outlined below using actual SIPRI TIV: transfer of a newly produced complete weapons system; a transfer of surplus weapons; a transfer of significant components for a major conventional weapons system; and a licensed production arrangement. All of the examples given are for items delivered or ordered from Germany in 2009.
- The transfer of newly produced complete weapons systems: In 2009, Germany delivered 6 Eurofighter combat aircraft to Austria. One Eurofighter is valued at 55 million SIPRI TIV. Therefore the delivery is valued at 330 million SIPRI TIV.
- Transfer of surplus weapons: In 2009, Germany delivered 43 surplus Leopard-2A4 tanks to Chile. One Leopard-2A4 tank is valued at 4 million SIPRI TIV and a used version is valued at 1.6 million SIPRI TIV (40 per cent of the value of a new version). Therefore, the delivery is valued at 68.8 million SIPRI TIV.
- Transfer of significant components for major conventional weapons systems: In 2009, Germany delivered 8 MTU-8000 diesel engines for frigates to Singapore. One MTU-8000 diesel engine is valued at 4 million SIPRI TIV. Therefore the delivery is valued at 32 million SIPRI TIV.
- Licensed production arrangement: In 2009 the Republic of Korea was granted a license to produce one Type-209PN submarine. One Type-209PN submarine is valued at 275 million SIPRI TIV. Therefore the delivery is valued at 275 million SIPRI TIV.
