HS Code 7104.10 – Stones; piezo-electric quartz, whether or not worked or graded but not strung, mounted or set; ungraded synthetic or reconstructed precious or semi-precious stones, temporarily strung for convenience of transport

HS code 7104.10 is the 6-digit subheading for stones, piezo-electric quartz, whether or not worked or graded but not strung, mounted or set, ungraded synthetic or reconstructed precious or semi-precious stones, temporarily strung for convenience of transport. It is used for quartz crystal oscillators, quartz resonators, synthetic sapphire boules, synthetic ruby rods and lab-grown cubic zirconia.

What HS 7104.10 covers

This HS code covers two distinct categories: piezo-electric quartz and ungraded synthetic or reconstructed precious/semi-precious stones temporarily strung for transport. Piezo-electric quartz is crucial for its ability to generate an electric charge under mechanical stress, making it vital for electronics like oscillators, sensors, and filters. The trade involves specialized manufacturers supplying the tech industry. The second part covers lab-grown or re-formed stones, often mimicking natural gems, which are temporarily strung for ease of handling and shipping before final processing or setting. Importers and exporters include electronics component suppliers, jewelry component manufacturers, and specialized stone dealers. Key considerations are the purity and frequency stability for quartz, and the appearance and cost-effectiveness for synthetic stones.

Codes often confused with 7104.10

Common mistake. Piezo-electric quartz might be confused with natural quartz (250610) if not specified as 'piezo-electric'. Synthetic stones could be confused with natural precious stones (7103) if not clearly identified as synthetic or reconstructed.

Top exporters and importers of HS code 710410, 2025

In 2025, the largest exporter of HS code 710410 in UN Comtrade data was Japan, with 32% of world exports; the largest importer in UN Comtrade data was Thailand, with 23% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
