While Koch-Glitsch was conducting its internal probe of illicit payments for contracts, the U.S. government was investigating Koch’s European unit on another front: sales to Iran.
On Aug. 14, 2008, investigators from the U.S. Department of Homeland Security met with George Bentu, who had worked as a sales engineer from 2001 to 2007 for Koch-Glitsch in Germany, Bentu says. In a four-hour interview at the U.S. consulate in Frankfurt, the officials asked about documents showing details of the company’s trades with Iran, he says.
Internal company records show that Koch Industries used its foreign subsidiary to sidestep a U.S. trade ban barring American companies from selling materials to Iran. Koch-Glitsch offices in Germany and Italy continued selling to Iran until as recently as 2007, the records show.
The company’s products helped build a methanol plant for Zagros Petrochemical Co., a unit of Iran’s state-owned National Iranian Petrochemical Co., the documents show. The facility, in the coastal city of Bandar Assaluyeh, is now the largest methanol plant in the world, according to IHS Inc., an Englewood, Colorado-based provider of chemicals, energy and economic data.
