“04.02.69 The Office for Foreign Assets Control of the Treasury Department issued a Note stating that it had reasons to believe that the nickel granulates produced in the USSR could be made, wholly or partly, with nickel of Cuban origin. It was communicated that as from February 5, 1969, nickel granulates imports made directly or indirectly from the USSR would be detained by Customs until their release from Customs or other provision were authorized by the Office for Foreign Assets Control, under the provisions of the Cuban Assets Control Regulations.” [Pro Embargo]
