As part of Project 922, German firms such as Karl Kolb helped build Iraqi chemical weapons facilities such as laboratories, bunkers, an administrative building, and first production buildings in the early 1980s under the cover of a pesticide plant. Other German firms sent 1,027 tons of precursors of mustard gas, sarin, tabun, and tear gasses in all. All told, 52% of Iraq's international chemical weapon equipment was of German origin. One of the contributions was a £14m chlorine plant known as "Falluja 2", built by Uhde Ltd, a UK subsidiary of a German company; the plant was given financial guarantees by the UK's Export Credits Guarantee Department despite official UK recognition of a "strong possibility" the plant would be used to make mustard gas. The guarantees led to UK government payment of £300,000 to Uhde in 1990 after completion of the plant was interrupted by the first Gulf War. In 1994 and 1996 three people were convicted in Germany of export offenses.
France also provided glass-lined reactors, tanks, vessels, and columns used for the production of chemical weapons. Around 21% of Iraq’s international chemical weapon equipment was French. 75,000 shells and rockets designed for chemical weapon use also came from Italy. About 100 tons of mustard gas also came from Brazil. The United States exported $500 million of dual use exports to Iraq that were approved by the Commerce Department. Among them were advanced computers, some of which were used in Iraq’s nuclear program. Austria also provided heat exchangers, tanks, condensers, and columns for the Iraqi chemical weapons infrastructure, 16% of the international sales. Singapore gave 4,515 tons of precursors for VX, sarin, tabun, and mustard gasses to Iraq. The Dutch gave 4,261 tons of precursors for sarin, tabun, mustard, and tear gasses to Iraq. Egypt gave 2,400 tons of tabun and sarin precursors to Iraq and 28,500 tons of weapons designed for carrying chemical munitions. India gave 2,343 tons of precursors to VX, tabun, Sarin, and mustard gasses. Luxembourg gave Iraq 650 tons of mustard gas precursors. Spain gave Iraq 57,500 munitions designed for carrying chemical weapons. In addition, they provided reactors, condensers, columns and tanks for Iraq’s chemical warfare program, 4.4% of the international sales. China provided 45,000 munitions designed for chemical warfare.
