(2) The exportation of such goods, technology, or services from the United States to Iran was subject to export license application requirements under any United States regulations in effect on May 6, 1995, or thereafter is made subject to such requirements imposed independently of this part (see § 560.414).
(1) Substantially transformed into a foreign-made product outside the United States; or
