U.S. exports of Diamonds, Rough and Unsorted (SITC 66721) totaled $12K in August 2026, exported to 3 countries.
Last updated: August 2026 dataRough, unsorted diamonds — as extracted from the mine and not yet sorted by quality, size, or gem versus industrial grade — are subject to the Kimberley Process Certification Scheme (KPCS), which requires a government-validated certificate of origin accompanying every shipment to prevent trade in conflict diamonds. The US implemented KPCS requirements through the Clean Diamond Trade Act, and CBP enforces certificate verification at entry; shipments lacking a valid KP certificate are refused importation. The unsorted nature of this heading means a single parcel may contain both gem-quality and industrial-quality stones, and the commercial value can vary dramatically depending on the eventual sort outcome.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Every shipment of rough diamonds must be accompanied by a Kimberley Process Certificate issued by the exporting country's designated authority. The certificate must be in a tamper-resistant container sealed with the KP certificate attached. CBP verifies the certificate at entry; shipments without a valid certificate are refused. The US KP authority is the US Census Bureau, which also handles US export certificates.
Because unsorted rough diamonds contain a mix of gem-quality and industrial-quality stones of varying sizes, transaction value is the standard CBP appraisement method, but it can be difficult to verify without a sort. CBP may request additional documentation — such as the seller's sort estimates or independent valuation — if the declared value appears inconsistent with the parcel's characteristics. Importers should retain all purchase documentation and any pre-shipment valuation reports.
