Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not plain weave (e.g., twill)
Non-plain weave closed fabrics move to 7019.63.60, as plain weave is specific to this subheading.
If coated or laminated with textile treatment
Coated glass fabrics for technical uses classify under Chapter 59 as textile-covered rather than raw glass fiber articles.
If for bulk mineral wools not filament-based
Non-filament silica wools per Chapter Note fall in 6806 if lacking >60% SiO2 or specific oxide contents.
