About HS Code 700232

This HS code specifies unworked glass tubes characterized by a very low linear coefficient of thermal expansion (CTE), not exceeding 5 x 10⁻⁶ per Kelvin within a temperature range of 0-300 degrees C. This property typically indicates borosilicate glass or similar heat-resistant compositions, making them ideal for applications requiring high thermal shock resistance and dimensional stability under varying temperatures. These tubes are crucial for laboratory glassware, pharmaceutical packaging, and specific industrial process equipment. Major traders include specialized glass manufacturers, pharmaceutical suppliers, and scientific equipment distributors. The low CTE is a critical performance characteristic distinguishing these tubes, ensuring reliability and safety in demanding environments where thermal stress is a concern.

Products Under This Code

Borosilicate glass laboratory tubes, pharmaceutical glass tubing, heat-resistant industrial glass tubes, thermometer glass blanks, solar collector tubes (unworked), high-temperature process tubes, medical glass tubing

Real World Examples

Schott Duran, Corning Pyrex, Kimble Chase, specific pharmaceutical glass tubing manufacturers (e.g., Gerresheimer)

Common Misclassification

Can be confused with 700239 (other unworked glass tubes) if the specific CTE property is not verified, or 7017 (laboratory, hygienic or pharmaceutical glassware) if already formed into finished articles.

Products Classified Under 7002.32

Industry

This code belongs to the Automotive & Vehicles industry.

Trade Overview

Germany, Japan, and the USA are primary exporters, while the USA, China, and India are significant importers for pharmaceutical and laboratory sectors.
