The Kimberley Process Certification Scheme, abbreviated as KPCS, aims to eradicate the illegal trade of conflict diamonds in Africa to maintaining peace and stability, and is an international trade scheme that preserves the order of rough diamond trade.

In accordance with Resolution 55/56 of the United Nations General Assembly, the KPCS was adopted by the Interlaken Declaration on 5 November 2002 in Switzerland. It has been officially implemented since 1 January 2003, with the main objective of establishing a certification scheme for the international trade in rough diamonds that regulates, supervises and controls the import, export and transit trade of rough diamonds.

The Macao Special Administrative Region implemented the KPCS through the People’s Republic of China on 1 October 2019, with Law No. 15/2019 - Law on Implementation of the Kimberley Process Certification Scheme for the International Trade in Rough Diamonds entering into force on the same day. In accordance with the requirements, all international trade in rough diamonds must be accompanied by a Kimberley Process (KP) Certificate issued by the government of the exporting country or territory, and shall be limited to only among KP member, which prohibit import of rough diamonds in absence of a Certificate issued by a KP member, as well as export of rough diamonds to non-KP members.

Currently, there are 55 participants in the KP representing 82 countries.
