This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If woven rather than non-woven
Woven glass fabrics for electrical use classify under 7019.40 even if colored, separate from mechanically bonded non-wovens.
If fully impregnated and cured
Cured composite sheets with plastic matrix classify as plastic plates under Chapter 39, not glass fabrics.
If heavier roving construction
Prepregs using rovings 1050+ decitex use 7019.62.20 instead of the 'other' .90 subheading.
