Top One Zone, LLC

​Tina Chen, also known as Ya When Chen, Wen Tina Chen, Tina Dunbar, and Tina Dubner, was the owner of Top One Zone, LLC, a company exporting electronic and computer components from her residence in Las Vegas, Nevada. Between November 2015 and May 2019, Chen conspired with others to purchase goods from U.S. companies and export them to individuals in Iran through intermediaries in Hong Kong, thereby violating the International Emergency Economic Powers Act (IEEPA) and the Iranian Transactions and Sanctions Regulations. She concealed the identities of the end-users and lacked the necessary licenses from the Office of Foreign Assets Control (OFAC) of the U.S. Department of the Treasury. ​

On February 23, 2023, Chen was convicted in the U.S. District Court for the District of Nevada for exporting goods to Iran without the required OFAC licenses. She was sentenced to 13 months of confinement, three years of supervised release, and a $100 assessment. Consequently, her export privileges were revoked until February 23, 2033.
