HS Code 7102.31 – Diamonds; non-industrial, unworked or simply sawn, cleaved or bruted, but not mounted or set
HS code 7102.31 is the 6-digit subheading for diamonds, non-industrial, unworked or simply sawn, cleaved or bruted, but not mounted or set. It is used for rough gem-quality diamonds, uncut diamonds, unpolished diamonds, diamond roughs for jewelry and cleaved diamonds.
What HS 7102.31 covers
This code covers rough, natural diamonds destined for jewelry, before significant cutting and polishing. These are the foundational raw materials for the global diamond industry, primarily traded by major mining companies and specialized rough diamond dealers. Key aspects of this trade include adherence to the Kimberley Process Certification Scheme, which is crucial for preventing conflict diamonds from entering the legitimate supply chain and ensuring ethical sourcing. The intrinsic value of these unworked stones is meticulously assessed based on their potential for carat weight, color, clarity, and optimal cut, even in their raw state. Major global trading hubs such as Antwerp, Dubai, and Mumbai specialize in the import and export of these unworked stones, where they undergo initial sorting, valuation, and preparation for the subsequent stages of transformation. The trade in rough diamonds is highly concentrated, with a few dominant players controlling the supply chain from the mine to the initial market. This concentration influences pricing and availability, making market intelligence vital for participants.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
