Case Study: Graff Diamonds achieves better customs control and reduced duty spend with Descartes

Graff Diamonds New Standards for Customs Declarations Processes with Descartes’ Electronic Import Customs Solution

Graff Diamonds, the luxury jewellery company behind some of the world’s most valuable pieces, needed a better way to manage complex customs processes across global shipments. As it relied on spreadsheets to track imports, Outward Processing Relief (OPR), and customs warehouse activity, the risk of missed diversions and unnecessary duty payments created significant manual work and compliance exposure. Graff Diamonds turned to Descartes’ Electronic Import Customs Solution to bring more structure to its import customs operations.

Descartes implemented a tailored, cloud-based solution that integrated Graff Diamonds’ warehouse and OPR inventory processes, replacing manual spreadsheet tracking with automated item-level visibility, audit trails, and management reporting. The result was improved customs compliance, better inventory control, faster processes, and significant duty savings by ensuring eligible goods were properly tracked and reimported within the two-year OPR window.
