HS Code for Laboratory quartzware

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.

Products Included

Common Misclassification

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.
