Borosilicate Glass Test Tubes from China
Unworked borosilicate glass tubes used primarily in laboratory settings for scientific experiments and sample containment. They fall under HTS 7002.39.00 as unworked glass tubes, without any drawn, blown, or further processing beyond basic tube formation. These tubes are essential for applications requiring thermal resistance and chemical durability.

Import Tips
• Verify the tubes are unworked (no cutting, annealing post-formation, or coatings) to avoid reclassification under 7002.32 or Chapter 70 worked glass
• Provide chemical composition certificates confirming borosilicate material for customs valuation and compliance
