Reza Dindar, 44, was arrested in Panama in July at the request of U.S. authorities and transferred to the United States last week. He made an initial appearance in U.S. District Court in Seattle, with arraignment scheduled for May 1, according to officials.

Prosecutors allege that Dindar conspired to violate longstanding U.S. trade sanctions by acquiring military sonar components under false pretenses and rerouting them to Iran. The indictment, unsealed Friday, charges him with conspiracy, smuggling and money laundering.

According to court documents, Dindar operated a company, New Port Sourcing Solutions, based in Xi’an, China, and between 2011 and 2012 arranged the purchase of parts for three military sonar systems from a business in Washington state.

Prosecutors said the transactions were carried out using deceptive practices, including misrepresenting the final destination of the equipment and asserting that no export license was required.

The components, valued at $97,600, were allegedly shipped first to China and then covertly transferred to Iran, in violation of U.S. sanctions imposed in 1995 and reinforced in 2001.Authorities have not disclosed Dindar’s whereabouts in the years between the alleged offenses and his arrest.

His attorney, Farhad Alavi, declined to comment.The case underscores ongoing U.S. enforcement efforts targeting alleged sanctions evasion networks involving dual-use or military-sensitive technologies.

In a separate matter, federal prosecutors said a Los Angeles woman was arrested over the weekend on suspicion of assisting Iran in trafficking weapons to Sudan, though officials said the cases are unrelated.
