What HS 7103.91 covers

This signifies a crucial stage in the gemstone supply chain where raw stones have been expertly cut, faceted, and polished, transforming them into valuable, ready-to-be-set gems. Major players in this trade are specialized gem dealers, high-end jewelry manufacturers, and luxury retailers.

Quality, clarity, color, and cut are paramount in determining their market value.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
