In order to adhere to this new law, President George W. Bush signed Executive Order 13312. According to a CRS report, the Bush administration began implementing KPCS before the passage of the House of Representatives Bill H.R. 1584 of the 108th congress, which became public law 108-19. The Act, signed under President George H. W. Bush, was set to be in effect until December 31, 2006. In 2006, this was extended to 2012, and in 2009, President Barack Obama confirmed the Waiver Certification to remain in effect through December 31, 2012. It does not appear to have been re-certified after December 31, 2012. The implementation of the KPCS is coordinated by the State Department’s Office of Threat Finance Countermeasures in the Bureau of Economic and Business Affairs. A Kimberley Process Implementation Coordinating Committee was also established in 2003 to implement the act, including officials from the Departments of State, Treasury, Commerce, Homeland Security, and the Office of the United States Trade Representative. The person in charge of coordinating the implementation is U.S. State Department’s Special Advisor for Conflict Diamonds, Brad Brooks-Rubin. There has been some debate over the effectiveness of the trade act, specifically the regulations set in place by KPSC. Some critics argue that the KPCS was set in place to allow consumers to buy diamonds without guilt, as opposed to effectively regulating the diamond market. It is thought that the KPSC doesn’t actually address the illegal diamond trade as well as it should. Global Witness decided to leave the KPCS in 2011 due to their dissatisfaction with the ability of KPCS to deal with much of the trade in conflict diamonds. However, others argue that KPCS has made substantial gains in decreasing the illegal market trade. One issue associated with the Clean Diamond Trade Act is that the United States does not inspect rough diamonds coming in or out of the country, so many traders have nothing to deter them from illicit trade. It is suggested that the United States implement more intensive reporting and inspection of rough diamonds to the ensure the success of the trade act. The United States also lacks an agency in charge of diamond import confirmations, which allows traders to bypass the requirement of reporting the receipt of the diamond shipment within 15 days of the arrival. The U.S. Customs and Border Protection (CBP) is the agency in charge of overseeing incoming diamond shipments and conducting examinations of shipments. There is also little oversight of the U.S. Kimberley Process Authority (USKPA), who are responsible for issuing Kimberley Process certificates, so no one supervises the company making sure that USKPA adheres to KPCS standards.
