Cuba DispatchBackground
The Cuba Sanctions Regulations are codified at 31 CFR part 516 and administered by the US Treasury's Office of Foreign Assets Control. They implement Executive Order 14404 under the International Emergency Economic Powers Act, using The National emergency declared in Executive Order 14380. The rulebook took effect on 30 September 2026.
Part 516 stands beside the older Cuban Assets Control Regulations at part 515. The two rulebooks rest on different authorities and operate independently, so permission under one does not override a prohibition under the other. OFAC initially published part 516 in abbreviated form to give immediate guidance. It said fuller definitions, interpretations, general licences and other provisions would follow. That planned expansion matters because the initial text establishes the sanctions framework without yet supplying every operational detail.
