E.O. 13846 does not make sanctionable the export of finished vehicles to Iran if no further assembly or manufacturing is required. As such, exporting fully assembled and finished vehicles to Iran for sale would not be sanctionable, so long as the transaction is consistent with U.S. sanctions, including that it does not involve a sanctioned person.
In contrast, “auto kits” (or “knock-down kits”) exported to Iran for assembly in Iran would be considered goods or services used in connection with the automotive sector of Iran and the export of such kits to Iran would be sanctionable if the transaction is “significant.” (See FAQ 289 for an interpretation of the term “significant.”)
