HS code for Unsorted diamonds: 7102.10
Diamonds, whether or not worked, but not mounted or set, unsorted.
Classification of unsorted diamonds under HS 7102.10
Unsorted diamonds are classified under HS code 7102.10. This classification is unique within Chapter 71, which covers natural or cultured pearls, precious or semi-precious stones, and precious metals. Heading 7102 is dedicated to diamonds, whether or not worked, but not mounted or set. The subheading 7102.10 is specifically for 'unsorted' diamonds. These are typically rough diamonds as they are recovered from the mine (run-of-mine) and have not yet been graded or categorized into industrial-quality or gem-quality stones. In the diamond trade, sorting is a critical step where stones are evaluated for clarity, color, size, and industrial utility. Until this technical evaluation is completed and the stones are separated into distinct commercial categories, they remain under 7102.10. This code is vital for international monitoring bodies, such as the Kimberley Process, to track the movement of rough diamonds from mining areas to sorting centers. Once the diamonds are sorted, they must be reclassified into industrial (7102.21) or non-industrial (7102.31) subheadings.

Codes often confused with 7102.10
Common mistake. Unsorted diamonds are frequently misclassified as industrial diamonds (7102.21) or non-industrial/gem diamonds (7102.31). The error occurs when the exporter assumes the end-use before the formal sorting process is complete. Additionally, they should not be confused with synthetic or reconstructed diamonds, which are classified under heading 7104. Only natural, unworked, and ungraded diamonds belong in 7102.10.

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).
