What were the main changes in the March 16, 2016 rule?The rule allowed vessels departing the United States on temporary sojourn to Cuba with cargo for other destinations to travel to Cuba under a license exception rather than having to obtain a license for the cargo bound for those other destinations to transit Cuba. The rule also authorized exports of certain items to persons authorized by the Department of the Treasury to establish and maintain a physical or business presence in Cuba. Finally, the rule adopted a licensing policy of case-by-case review for exports and reexports of items that would enable or facilitate exports of items produced by the private sector in Cuba, subject to certain limitations.
