Product classification
HS code for Laboratory quartzware: 7017.10
Glassware, laboratory, hygienic or pharmaceutical, whether or not graduated or calibrated, of fused quartz or other fused silica.
Classification of laboratory quartzware under HS 7017.10
Laboratory quartzware is classified under HS code 7017.10. This specific code is reserved for laboratory, hygienic, or pharmaceutical glassware made of fused quartz or other fused silica. Fused quartz is distinguished by its high purity and its ability to withstand extremely high temperatures and thermal shock compared to standard borosilicate or soda-lime glass. Chapter 70 covers glass and glassware, and heading 7017 is dedicated to technical glassware used in scientific environments. The 7017.10 subheading is prioritized when the material composition is predominantly fused silica. This includes items that may be graduated or calibrated for volumetric measurement, though the material composition is the primary determinant for this specific subheading. Quartzware is essential in laboratories performing high-heat applications, UV spectroscopy, or semiconductor research where chemical inertness and thermal stability are paramount. The classification remains the same regardless of whether the item is a simple tube or a complex custom-fabricated vessel, provided it is made of fused silica.

Codes often confused with 7017.10
Common mistake. The most common misclassification is using HS code 7017.20, which is intended for glassware with a low coefficient of expansion, such as borosilicate glass (e.g., Pyrex). While both are used in labs, quartzware (7017.10) has a much higher silica content and higher heat resistance. Another error is using 7017.90, which is the catch-all for other types of laboratory glass like soda-lime glass.
Top exporters and importers of HS 701710 (the code used for laboratory quartzware), 2025
In 2025, the largest exporter of HS 701710 (the code used for laboratory quartzware) in UN Comtrade data was Japan, with 21% of world exports; the largest importer in UN Comtrade data was the United States, with 26% 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).
