Borosilicate Glass Test Tubes 100mm
Unworked borosilicate glass tubes, 100mm in length, used primarily in laboratory settings for chemical experiments and sample containment. Classified under HTS 7002.39.0010 as unworked glass tubes not exceeding 200mm, without any drawing, cutting to shape beyond basic form, or other working processes post-annealing. They retain the character of raw glass tubes per Chapter 70 notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If length exceeds 200mm
Tubes over 200mm fall under the specific subheading for longer unworked glass tubes in 7002.32.
If drawn and further worked into finished laboratory articles
Once cut to precise shape, annealed, or processed beyond basic form, they become laboratory glassware in 7017.
If sold as articles of other glass not elsewhere specified
If the tubes have characteristics of finished articles rather than raw unworked material, they may classify in 7020.

Import Tips & Compliance
• Verify tube length does not exceed 200mm and confirm unworked status (no annealing post-processing or coatings) to avoid reclassification under 7002.32 or 7017
• Provide mill test certificates showing chemical composition (e.g
• borosilicate) and dimensions for customs valuation and origin claims
