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. The closest oversight comes from the Department of State, who “convene periodic teleconferences with the USKPA”.
