7017 - Laboratory, hygienic or pharmaceutical glassware, whether or not graduated or calibrated:

This HTS category, 7017, encompasses a broad range of glassware specifically designed for laboratory, hygienic, or pharmaceutical applications. These items are distinguished by their intended use in scientific research, medical procedures, or the preparation and dispensing of medicinal products. The glassware may be plain or feature graduations and calibrations to ensure precise measurements, a critical requirement for these specialized fields.

While other glass products exist within Chapter 70, this section focuses exclusively on the functional aspects of laboratory, hygienic, and pharmaceutical use. For instance, it differentiates itself from general glassware (which might be found in other chapters or more general subheadings) by its specialized nature and higher standards of accuracy and purity. The materials and manufacturing processes for glassware in this category are often more stringent to prevent contamination and ensure reliable results in critical applications.

The subcategories within 7017 further refine the classification based on the material composition of the glassware. "Of fused quartz or other fused silica" (7017.10) addresses items made from these highly inert and heat-resistant materials, often used in demanding laboratory environments. "Of other glass having a linear coefficient of expansion not exceeding 5 x 10-6 per Kelvin" (7017.20.00.00) specifically classifies glassware made from borosilicate or similar types of glass renowned for their thermal shock resistance. Finally, "Other" (7017.90) serves as a residual category for laboratory, hygienic, or pharmaceutical glassware not fitting the specific material definitions of the preceding subheadings.
