Apstar 6 was built as an ITAR-free satellite, containing no restricted U.S. components. Under the U.S. ITAR regulations, U.S. satellite components may not be exported for launch on Chinese rockets. However, the U.S. Department of State did not accept the ITAR-free status of these satellites and fined the US company Aeroflex $8 million for selling ITAR components. In 2013, Thales Alenia discontinued its ITAR-free satellite line.
