U.S. Sanctions Programs

Various countries are subject to U.S. economic and trade sanctions. The sanctions can be either “limited” or “comprehensive”, and for certain countries (such as Iran and Cuba) can be extremely restrictive.

These sanctions may require obtaining governmental approval before conducting research with, buying materials from, or engaging in other activities involving the sanctioned country.

Countries or regions subject to the most restrictive sanction programs are:

  • Cuba
  • Iran
  • North Korea
  • Syria
  • Republic of the Sudan (also known as North Sudan; not South Sudan)
  • the Crimea Region of Ukraine

More limited  restrictions apply to Balkans, Belarus, Burma, Burundi, Central African Republic, Democratic Republic of the Congo, Iraq, Lebanon, Libya, Somalia, South Sudan, Ukraine/Russia, Venezuela, Yemen and Zimbabwe.

For a complete list of sanctioned countries, visit the Sanctions Programs and Country Information page on the U.S. Department of Treasury's website. It is updated periodically and has the most recent information.

Any proposed transaction, contract, collaboration, purchase, or other transaction in, or involving, a sanctioned country or an entity (whether governmental, non-profit, or commercial), or individual based in a sanctioned country, should be discussed in advance with the University's Office of the General Counsel or the Office of Research Compliance and Training.
