HS-6 · Subheading
700232
Glass; unworked, tubes, of glass having a linear coefficient of expansion not exceeding 5 x 10 (to the minus 6), (or 0.000005) per Kelvin within a temperature range of 0-300 degrees C
Heading 7002 — Glass in balls (other than microspheres of heading no. 7018), rods or tubes, unworked
Chapter 70: Glass and glassware
Plain-language overview
Use HS-6 700232 when importing or exporting unworked glass tubes that have a linear coefficient of expansion not exceeding 5 x 10^-6 per Kelvin. For example, if you’re shipping glass tubes intended for scientific applications that require precise thermal stability, this code applies.
This code specifically covers unworked glass tubes, which differ from HS-6 700231, which includes unworked glass rods. While both are unworked glass products, the distinction lies in their form and intended use.
When classifying glass tubes, ensure they meet the thermal expansion criteria outlined in this subheading. If your product does not meet these specifications, you may need to consider other codes under heading 7002.
Common applications for these glass tubes include laboratory equipment, thermal insulation in electronics, and components in high-temperature environments. Understanding the precise specifications is crucial for compliance and accurate customs declarations.
