HS Code for Quartz beakers

Quartz beakers are specialized laboratory vessels made from fused silica or fused quartz, known for their high thermal resistance and chemical purity. These items are classified under Chapter 70, which pertains to glass and glassware. Heading 7017 is dedicated to laboratory, hygienic, or pharmaceutical glassware, whether or not graduated or calibrated. Subheading 7017.10 specifically identifies glassware made of fused quartz or other fused silica. This classification is determined by the intended use of the product (laboratory environment) and the specific material composition (fused silica). Unlike standard laboratory glassware made from borosilicate glass, quartz labware is distinguished by its ability to withstand extreme temperatures (up to 1200°C) and its transparency to ultraviolet light. The Harmonized System distinguishes these based on the coefficient of expansion and the silica content. For a beaker to fall under 7017.10, it must be a finished article of laboratory equipment and be composed of silica with a purity typically exceeding 99.9%. This ensures that the high-performance characteristics of the material are recognized for tariff and regulatory purposes.

Products Included

• Fused quartz beakers
• Fused silica flasks
• Quartz test tubes for laboratory use
• Quartz crucibles for chemical analysis
• Graduated quartz cylinders
• Quartz combustion boats

Common Misclassification

Quartz beakers are often confused with standard borosilicate laboratory glassware, which is classified under HS code 7017.20 (glass having a linear coefficient of expansion not exceeding 5x10-6 per Kelvin). They may also be misclassified under 7017.90 if the material is not correctly identified as fused silica. Furthermore, if the quartz item is not for laboratory use but for industrial or kitchen use, it might be incorrectly placed in 7013.42, which covers glassware for kitchen purposes.

FAQ

What is the HS code for Quartz beakers?

The HS code for laboratory beakers made of fused quartz or fused silica is 7017.10.

Are quartz tubes used in furnaces classified here?

If the tube is a finished piece of laboratory apparatus, it is 7017.10. However, if it is unworked raw tubing, it should be classified under HS code 7002.31.
