HS Code 7104.29 – Stones; synthetic or reconstructed precious or semi-precious n.e.c. in heading 7104, unworked or simply sawn or roughly shaped

HS code 7104.29 is the 6-digit subheading for stones, synthetic or reconstructed precious or semi-precious n.e.c. in heading 7104, unworked or simply sawn or roughly shaped. It is used for synthetic diamond rough, lab-grown moissanite crystals, synthetic ruby boules, reconstructed turquoise blocks and synthetic emerald ingots.

What HS 7104.29 covers

This category encompasses synthetic or reconstructed precious and semi-precious stones that are in their raw, unworked state, or have only undergone basic shaping like sawing. Unlike natural stones, these are lab-created or formed from fragments of natural stones, offering a more affordable and often ethically controlled alternative. This trade is driven by the demand for consistent quality and lower cost materials for both jewelry and various industrial applications. Manufacturers of these stones, as well as jewelers and industrial suppliers, are key participants in this market. Quality control, consistency in material properties, and cost-effectiveness are crucial factors for trade in these unworked synthetic materials, which serve as the foundation for a wide range of finished products.

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).
