Kimberley Process Certification Scheme

The Kimberley Process Certification Scheme (KPCS) is an intergovernmental certification regime for international trade in rough diamonds. In operation since 2003, it requires participants to establish domestic controls, issue or validate certificates for rough-diamond shipments, use tamper-resistant containers and trade only with other participants. The Kimberley Process forum works by consensus; national authorities implement the scheme through their own law.

Origin

The scheme grew from efforts to stop diamonds financing armed rebellion in Angola and Sierra Leone, including the sanctions on UNITA and Sierra Leone diamond controls. UN General Assembly Resolution 55/56 of 1 December 2000 supported a certification approach. Participants adopted the KPCS core document in 2002, and implementation began in 2003. The KPCS is distinct from measures imposed by the United Nations Security Council and from private industry warranties.

Mechanism

The Kimberley Process website reviewed on 30 July 2026 reported 60 participants representing 86 countries, because the European Union and its 27 member states count as one participant. A rotating chair leads the process, while the permanent secretariat in Botswana provides administrative support. These bodies do not replace national customs and licensing authorities. The website reported that participants account for approximately 99.8 per cent of global rough-diamond production. That is an operator measure of production coverage, not a finding that 99.8 per cent of conflict-diamond trade has been prevented.

Assessment and contestation

The core document defines conflict diamonds narrowly as rough diamonds used by rebel movements or their allies to finance conflict aimed at undermining legitimate governments. It does not cover every human-rights abuse, state violence or polished-diamond transaction. This boundary has driven longstanding criticism of the scheme. Causal claims about the historical decline in conflict-diamond trade must also account for the end of wars and separate UN measures.

Restrictions on Russian diamonds adopted by the Group of Seven and European Union after 2022 sit outside KPCS authority. The European Union's sanctions timeline records its own import restrictions. Disagreement over whether the KPCS definition should change does not convert those external restrictions into Kimberley Process decisions. The scheme is therefore a case of certification-based trade control with a deliberately limited mandate.
