Pyrex-Type Borosilicate Glass Rods from China
Unworked solid glass rods made from borosilicate with controlled low thermal expansion (≤5 x 10⁻⁶/K), ideal for stirring rods, thermometer tubes, and scientific instrument components. HTS 7002.32.00.00 covers these as unworked rods of low-expansion glass before any fabrication.

Import Tips
• Include material safety data sheets (MSDS) confirming borosilicate composition and expansion coefficient for smooth clearance
• Import in standard lengths to maintain 'unworked' status; custom-cut rods risk reclassification
• Avoid common error of declaring with end-use info that suggests finished products, triggering scrutiny
