Many OFAC sanctions programs have exemptions that cover the mailing of items such as certain humanitarian donations, personal communications containing nothing of value, or informational materials like books, newspapers, and CDs. In addition, under each sanctions program, OFAC has established “general licenses” that authorize shipments under certain conditions. If no exemption or general license applies, a mailing may be allowed if the mailer applies for and obtains a “specific license” from OFAC.
