Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as rovings rather than woven fabric
Unwoven rovings classify in 7019.12; fabrication into weave changes to 7019.64.
If assembled into insulated electrical cable sheathing
When made into finished cable insulation, it falls under Chapter 85 electrical insulators.
If for retail-packaged sheets vs. bulk industrial rolls
Retail glass sheets shift to Chapter 70 other worked glass if not primarily fiber fabric.

Import Tips & Compliance
• Certify silica (SiO2) content if claiming fused quartz properties; chapter notes require this for glass definition
• Document end-use as industrial to avoid consumer goods scrutiny; provide buyer affidavits if needed
