On May 24, 2019 the Bureau of Industry and Security (BIS) published a final rule which moved Venezuela from Country Group B to Country Group D:1. This change from favorable to less favorable treatment related to exports was made due to national security concerns after the introduction of foreign military personnel and equipment into Venezuela.
Supplement No. 1 to Part 740 (Country Groups) has been amended to reflect this change.
