The Treasury Department's Office of Foreign Assets Control is revising the Rough Diamonds Control Regulations previously issued as an interim final rule. The regulations carry out the purposes of Executive Order 13312 of July 29, 2003, which implemented the Clean Diamond Trade Act and the Kimberley Process Certification Scheme for rough diamonds. Based on its experience and that of other involved agencies, OFAC is revising certain reporting and recordkeeping requirements of the regulations.
