Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for laboratory, technical or scientific use
Lab/technical glassware covers instrument windows separate from general optics.
If toughened for safety
Toughened (tempered) glass, even for instruments, falls under worked glass in 7007.
If integral parts of physical analysis instruments
Parts/accessories of instruments for physical/chemical analysis classify in 9027.
