Iranian national Amin Ravan and his Iran-based company IC Market Iran (IMI) have been charged with smuggling military antennas from the United States to Hong Kong and Singapore.  According to the Justice Department, 50 cavity-backed spiral antennas and five biconical antennas were exported from the United States to Corezing International without the required license.  After failing to procure the antennas directly from U.S. manufacturers, Ravan worked with Singapore-based Corezing International in order to disguise that the goods were destined for Iran.  Ravan also altered the range frequency of the antennas in an effort avoid detection by the U.S. company's export compliance officer.  The exports took place between July and September 2007.  Ravan was arrested in Malaysia in October 2012 and U.S. authorities are seeking his extradition.

Corezing also has offices in Hong Kong and China and two of its principals (Lim Kow Seng and Hia Soo Gan Benson) were separately indicted.  They were arrested in Singapore in 2011 and have since pled guilty to one count of conspiracy to violate the Arms Export Control Act. On September 20, 2013, Seng and Benson were sentenced to 37 and 34 months in prison, respectively.

Two other entities appear to be linked to this case, including Hossein Larijani and Rudolf Cheung.  Some of the illicit sales arranged by Ravan were allegedly destined for Larijani and his companies – Opto Electronics in Singapore and Paya Electronics in Iran.  Cheung was head of research and development at a Massachusetts-based company that was the source of some of the antennas.  Cheung pled guilty in January 2012 for his role in the conspiracy.
