Authorities believe Ali Saboonchi, 32, ran the Ace Electric Company to obtain goods to send them to businesses run by Arash Rashti Mohammad, 31, in Tehran, Iran, and the United Arab Emirates since November 2009, the five-count indictment said.
U.S. economic sanctions prohibit exporting to Iran.
Among the items included in the indictment were cyclone separators; used in pipelines to separate impurities, thermocouples, used to measure temperatures of liquids and gases; hydraulic valves and connectors; and other items.
Rashti got quotes, paid for the items, then had them shipped to others in the United Arab Emirates and China, the indictment said. Saboonchi was reimbursed for the goods.
Saboonchi is charged with conspiracy and four counts of illegally exporting to an embargoed country. He faces a maximum sentence of 20 years in prison.
Rashti is believed to be living in Iran.
