Drawn Soda-Lime Glass Sheet for Laboratory Slides
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If produced by float process instead of drawn
Float glass sheets fall under 7005, even if similar dimensions, as production method determines heading per HTS structure.
If further worked like edges ground or polished
Any processing beyond cutting to shape, such as grinding or drilling, moves it from sheets (7004) to glass articles (7016).
If safety-tempered or toughened
Tempered or toughened drawn glass sheets classify under 7007 as safety glass, regardless of original sheet status.

Import Tips & Compliance
• 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
