HS Code for Borosilicate glassware

Borosilicate glassware is precisely classified under HS code 701720 due to its unique material composition and specific functional applications. This Harmonized System subheading is dedicated to glassware designed for laboratory, hygienic, or pharmaceutical purposes, which exhibits a low linear coefficient of expansion—specifically, not exceeding 5 x 10^-6 per Kelvin within a temperature range of 0-300 degrees C. Borosilicate glass, renowned for its exceptional thermal shock resistance, chemical inertness, and mechanical strength, perfectly meets these stringent technical criteria. These properties render it indispensable for scientific research, medical diagnostics, and pharmaceutical manufacturing, where precision, durability, and safety under varying thermal and chemical conditions are paramount.

Products Included

• Laboratory beakers, flasks (e.g., Erlenmeyer, volumetric, round-bottom), and distillation apparatus
• Test tubes, culture tubes, and centrifuge tubes
• Pipettes, burettes, and graduated measuring cylinders
• Petri dishes, desiccators, and watch glasses
• Specific medical and pharmaceutical glass containers, such as vials and ampoules, requiring high thermal and chemical resistance for sterilization and storage
• Components for scientific instruments, including condensers and reaction vessels

Common Misclassification

Misclassification often occurs with other specialized glassware. HS code 701710 covers glassware made of fused quartz or other fused silica, which, while also used in laboratories, possesses distinct material properties and higher temperature tolerances compared to borosilicate glass. HS code 701790 serves as a residual category for other laboratory, hygienic, or pharmaceutical glassware not specifically covered by the preceding subheadings, typically for materials other than borosilicate or fused quartz. It is crucial to differentiate borosilicate items intended for domestic use, such as ovenware or baking dishes, which are classified under HS code 7013, as their primary function is not laboratory, hygienic, or pharmaceutical, despite being made from the same material.

FAQ

What is the HS code for Borosilicate glassware?

The HS code for borosilicate glassware, specifically when manufactured and intended for laboratory, hygienic, or pharmaceutical applications, is 701720.

What distinguishes borosilicate glassware from other types of laboratory glassware?

Borosilicate glassware is primarily distinguished by its low linear thermal expansion coefficient, typically not exceeding 5 x 10^-6 per Kelvin. This characteristic provides superior resistance to thermal shock, enabling it to withstand rapid and significant temperature changes without fracturing. This property is critical for applications involving heating, cooling, or sterilization processes common in scientific and medical environments.
