OFAC FAQ #187 · Iran Sanctions
Does the GHRAVITY E.O. prohibit me from exporting technology to companies that do business with Iran or Syria?
OFAC's answer
This [E.O.](https://ofac.treasury.gov/media/6491/download?inline) does not generally prohibit transactions involving persons that do business with Iran or Syria, unless the person has been designated pursuant to this order. You should consult with the Department of Commerce’s Bureau of Industry and Security (BIS) regarding exports to companies that do business with Syria.
