Uncolored Biaxial Closed Woven Roving Glass Cloth
This biaxial (0°/90°) closed woven fabric uses uncolored glass rovings for high-strength composite layups in aerospace and marine applications. HTS 7019.61.40.60 applies due to mechanical bonding, closed weave, and lack of coloration. Offers superior directional strength compared to standard weaves.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold in rolls >20 cm wide but as nonwoven mats
Width and bonding method determine precise subheading within nonwovens.
If in rectangular sheets ≤0.5 mm thick for other uses
Very thin glass sheets may classify under drawn/cast glass if not fibrous.

Import Tips & Compliance
• Submit directional weave diagrams showing biaxial pattern to confirm roving construction
• Ensure import declaration specifies 'mechanically bonded' to avoid nonwoven misclassification
• Maintain records of end-use restrictions if for defense applications requiring ITAR compliance
