Kimberley Process Certificate requirement: rough diamond consignments must be accompanied by KP Certificates for Customs clearance. Imports and exports of rough diamonds require a Kimberley Process Certificate (KP Certificate); the Gem and Jewellery Export Promotion Council (GJEPC) is the designated authority to verify, endorse and issue KP Certificates, retain originals with Customs, and provide validated copies for Bill of Entry or Shipping Bill filings. Customs will physically examine 25% of each consignment (minimum one lot), will not clear consignments without KP Certificates, and importers lacking originals have seven working days to produce them or face return of goods to the exporting authority.
