Must hold a legitimate export license as specified by the Mines and Minerals Act 2009.
Must give Precious Minerals Trading Directorate twenty four hours notice to prepare for valuation and export documentation.
Goods must be presented according to classifications as provided in export document "Schedule B". This document could be collected at the Precious Minerals Trading Directorate at the Bank of Sierra Leone building, 2nd floor, Siaka Stevens Street, Freetown.
The exporter is expected to declare the value of his/her goods in the stipulated Schedule B.
Goods must be accompanied by either the exporter himself/herself or a nominee who is a holder of a processing agent certificate.

KPCS rules and valuation

Diamond export depends on Kimberley Process rules and the highest applicable valuation for duty.

Diamond export must be exported to countries that are members of the Kimberley Process Certification Scheme (KPCS).
Diamonds imported into Sierra Leone must be accompanied by Kimberley Process Certificate from the exporting country.
Diamond exporters must note that the highest of the three valuations, namely the exporter's value, the Government Diamond Valuer's value, and the Independent Diamond Valuer's value, determines the 3% export duty payable to Government. Payment is effected at the Bank of Sierra Leone by the Exporter.
Valuation is done in the presence of the licensed exporter or his/her processing agent, a Senior Mines Monitoring Officer, and a Senior Customs Officer from the National Revenue Authority.

Routing and sealing

Destination rules, itinerary evidence, packet preparation, and sealed box handling are completed before certification.

Diamond exporters wishing to export goods to destinations out of the EU are required to route the shipment through the six designated countries: Belgium, Bulgaria, Czech Republic, Germany, Romania, and the UK.
Diamond exporters wishing to export to EU countries must show evidence, for example a flight itinerary.
After valuation, the goods are put into packets as directed by the exporter and placed in a box which is then wrapped and sealed.

Certificate and record keeping

The Kimberley Process certificate is issued, signed, photographed, and kept in official records.

A Kimberley Process certificate with serial number is issued showing details of the valuation. The certificate is signed by the Minister of Mines and Mineral Resources, the Government Diamond Valuer, and the Commissioner-General of National Revenue Authority or Senior Customs Officer.
Digital photographs of sealed parcel and attached KPCS certificate are taken and kept in the PMTD records for verification purposes.

Airport handover and validity

The sealed parcel, copies, receipts, and customs declaration forms move through the approved airport channel.

The sealed diamond parcel, KP Certificate photocopies, Schedule B photocopies, payment receipts, and completed sealed customs declaration forms are handed over to the exporter or processing agent for surrender to the Senior Customs Officer at the International Airport.
The validity of the KP certificate is one month after issue.
Photocopies of other export documents are given to the exporter to keep and distribute to relevant security and monitoring agencies at the international airport.
All precious minerals ready for export must go through the international airport only.
