Drawn Soda-Lime Glass Sheet for Laboratory Slides from China

Thin drawn glass sheets, rectangular in shape, measuring 0.1 mm thick and 0.25 m² in area, used primarily for manufacturing microscope slides. Classified under HTS 7004.90.05.00 as drawn glass in sheets not over 1.5 mm thick and not over 0.26 m², without further working beyond possible annealing. Meets chapter notes as not 'worked' pre-annealing and cut to shape does not change classification.

Import Tips

Verify exact dimensions and thickness with calipers to confirm under 1.5 mm and 0.26 m²; provide measurement certificates to CBP

Include mill test reports confirming drawn glass process and absence of absorbent/reflecting layers unless declared

Avoid common pitfall of misclassifying as float glass (7005); ensure documentation specifies 'drawn' production method
