HS code for Piezoelectric quartz: 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.
Classification of piezoelectric quartz under HS 7104.10
Piezoelectric quartz is classified under HS code 7104.10. This classification is found in Chapter 71, which covers precious or semi-precious stones and metals. Subheading 7104.10 specifically addresses synthetic or reconstructed quartz. While natural quartz is found in Chapter 25, the quartz used for piezoelectric purposes in modern electronics is almost exclusively synthetic, grown in high-pressure autoclaves to ensure a lack of impurities and consistent crystalline structure. The \"piezo-electric\" designation in this heading applies to quartz that has been worked (cut, sawn, or ground) into plates, bars, or other shapes suitable for electronic use, but—crucially—it has not yet been mounted with electrodes or placed in a holder. Once the quartz is mounted, it migrates to Chapter 85 (specifically 8541.60). Therefore, 7104.10 acts as the classification for the high-purity raw material or the semi-finished crystal blanks. This distinction is important for manufacturers who import crystal blanks to perform the final assembly and mounting. The classification ensures that the material is treated as a synthetic stone rather than a finished electronic component, which often carries different tariff implications and regulatory requirements. It also covers synthetic quartz that is not yet worked, provided it is intended for these technical applications.

Codes often confused with 7104.10
Common mistake. Piezoelectric quartz is often misclassified under 8541.60, which is reserved for crystals that have already been mounted with electrodes. It may also be confused with natural quartz (2506.10), but 7104.10 is specifically for synthetic or reconstructed material, which is the standard for piezoelectric applications.
Top exporters and importers of HS 710410 (the code used for piezoelectric quartz), 2025
In 2025, the largest exporter of HS 710410 (the code used for piezoelectric quartz) 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.
Figures cover everything classified under HS 710410, not only piezoelectric quartz.

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).

Questions about piezoelectric quartz
What is the HS code for Piezoelectric quartz?
The HS code for Piezoelectric quartz is 710410 (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). The HS code for synthetic or reconstructed piezoelectric quartz, whether or not worked but unmounted, is 7104.10.
How do I classify Piezoelectric quartz for customs?
Piezoelectric quartz is classified under HS code 710410 — 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. This is a 6-digit subheading level code.
Is natural quartz classified under this code?
No, natural quartz is classified under HS code 2506.10, unless it is a precious or semi-precious stone, in which case it falls under 7103.
Which countries are the top exporters of piezoelectric quartz (HS 710410)?
In 2025, the top exporters of HS 710410 (the code used for piezoelectric quartz) in UN Comtrade data were Japan ($40M, 32% of world exports), China ($29M) and the United States ($23M). World exports came to about $125M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of piezoelectric quartz (HS 710410)?
In 2025, the top importers of HS 710410 (the code used for piezoelectric quartz) in UN Comtrade data were Thailand ($21M, 23% of world imports), China ($19M) and Japan ($16M). World imports came to about $93M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Piezoelectric quartz the same in all countries?
