Section 560.502 - Effect of license or authorization(a) No license or other authorization contained in this part, or otherwise issued by the Office of Foreign Assets Control, authorizes or validates any transaction effected prior to the issuance of such license or other authorization, unless specifically provided in such license or authorization.(b) No regulation, ruling, instruction, or license authorizes any transaction prohibited under this part unless the regulation, ruling, instruction, or license is issued by the Office of Foreign Assets Control and specifically refers to this part. No regulation, ruling, instruction, or license referring to this part shall be deemed to authorize any transaction prohibited by any other part of this chapter unless the regulation, ruling, instruction, or license specifically refers to such part.(c) Any regulation, ruling, instruction, or license authorizing any transaction otherwise prohibited under this part has the effect of removing a prohibition contained in this part from the transaction, but only to the extent specifically stated by its terms. Unless the regulation, ruling, instruction, or license otherwise specifies, such an authorization does not create any right, duty, obligation, claim, or interest in, or with respect to, any property which would not otherwise exist under ordinary principles of law.(d) All transactions involving property and interests in property of the Government of Iran, an Iranian financial institution, or any other person whose property and interests in property are blocked pursuant to § 560.211 authorized under specific licenses issued pursuant to this part prior to February 6, 2012, are authorized, and such specific licenses shall remain in effect according to their terms, provided that such specific licenses have an expiration date. If a specific license issued pursuant to this part but not part 535 has no expiration date, then all transactions involving property and interests in property of the Government of Iran, an Iranian financial institution, or any other person whose property and interests in property are blocked pursuant to § 560.211 authorized under such a specific license were authorized until April 6, 2012, and such a specific license shall otherwise expire in its entirety on January 22, 2013. If a specific license issued pursuant to this part and part 535 has no expiration date, then all transactions involving property and interests in property of the Government of Iran, an Iranian financial institution, or any other person whose property and interests in property are blocked pursuant to § 560.211 authorized under such a specific license are authorized, and such a specific license shall remain in effect according to its terms. Nothing in this paragraph authorizes payments from blocked funds or debits to blocked accounts, except for payments from funds or debits to accounts blocked pursuant to part 535 that are authorized by specific licenses issued pursuant to this part and part 535 of this chapter.(e) Nothing contained in this part shall be construed to supersede the requirements established under any other provision of law or to relieve a person from any requirement to obtain a license or other authorization from another department or agency of the U.S. Government in compliance with applicable laws and regulations subject to the jurisdiction of that department or agency. For example, exports of goods, services, or technical data which are not prohibited by this part or which do not require a license by the Office of Foreign Assets Control, nevertheless may require authorization by the U.S. Department of Commerce, the U.S. Department of State, or other agencies of the U.S. Government. See also§ 560.701(d) .(f) No license or other authorization contained in or issued pursuant to this part authorizes transfers of or payments from blocked property or debits to blocked accounts unless the license or other authorization explicitly authorizes the transfer of or payment from blocked property or the debit to a blocked account.(g) Any payment relating to a transaction authorized in or pursuant to this part that is routed through the U.S. financial system should reference the relevant Office of Foreign Assets Control general or specific license authorizing the payment to avoid the blocking or rejection of the transfer.
