Plain Weave E-Glass Fabric for PCB Laminates
This is a closed woven plain weave fabric made from uncolored E-glass yarns, mechanically bonded without any coating or lamination. It is specifically designed for use in printed circuit board (PCB) laminates, providing electrical insulation and structural reinforcement. Classified under HTS 7019.63.40 as a non-colored, plain weave glass fiber fabric not otherwise specified.

More Specific Codes
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 coated or laminated
Coatings or laminations change classification to subheading 7019.62, as they alter the fabric's surface properties beyond mechanical bonding.
If in the form of woven fabrics of rovings
Fabrics made from rovings (bundled strands) rather than single yarns fall under 7019.40, differing from yarn-based plain weave.
If textile-coated with plastics for reinforcement
If impregnated or coated with plastics like PVC for textile reinforcement, it moves to Chapter 59 as textile fabrics with plastic coatings.

Import Tips & Compliance
• Verify yarn composition and weave type through lab testing to confirm plain weave and mechanical bonding, avoiding misclassification as coated fabrics
• Ensure documentation includes certification of 'not colored' status and absence of lamination to qualify for this subheading
• Be aware of common pitfalls like partial coloring during manufacturing, which shifts to colored variants under 7019.63.50
