HS code for Loose diamonds: 7102.39
Diamonds, non-industrial, (other than unworked or simply sawn, cleaved or bruted), but not mounted or set.
Classification of loose diamonds under HS 7102.39
Loose diamonds are classified under HS code 7102.39 because they are categorized as non-industrial diamonds that have been worked but are not yet mounted or set. The Harmonized System distinguishes between industrial-grade diamonds, used primarily for abrasive or cutting tools, and non-industrial diamonds intended for gemstones. Within the non-industrial category, diamonds are further differentiated by their level of processing. Code 7102.39 specifically applies to stones that have undergone faceting, polishing, or other decorative shaping processes. Because these diamonds are 'loose,' they are imported as individual stones or in batches without being integrated into jewelry pieces like rings or pendants. The classification relies on the physical state of the diamond and its intended use in the ornamental arts rather than industrial applications.

Codes often confused with 7102.39
Common mistake. A frequent misclassification occurs with HS code 7102.31, which is reserved for non-industrial diamonds that are unworked or simply sawn, cleaved, or bruted. If a diamond has been polished beyond the basic shaping required for cleavage, it must move to 7102.39. Another common error is using 7113.19, which covers finished articles of jewelry. If a diamond is even temporarily set in a finished precious metal mounting, it is no longer a loose diamond. Additionally, industrial diamonds are often confused with these stones; industrial diamonds fall under 7102.21 or 7102.29 depending on their worked state.

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).
