E-Glass Plain Weave Fabric 220 g/m² 9 Micron
This open plain weave glass fiber fabric weighs 220 grams per square meter with a filament diameter of 9 microns, classified under HTS 7019.66.40.21 due to its mechanical bonding, width over 30 cm, plain weave structure, uncolored filaments under 136 tex, and specific weight and diameter specs. It is commonly used in composite reinforcements for lightweight structural applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If filament diameter under 7 microns
Finer filaments shift to statistical suffix .20 within same subheading for different micron range.
If sold as woven fabric of rovings rather than filaments
Rovings are continuous bundles classified under 7019.40, distinct from filament-based fabrics.

Import Tips & Compliance
• Verify filament diameter (7-13 microns) and exact weight (>215 g/m²) via lab testing to confirm HTS 7019.66.40.21 classification
• Provide mill test certificates documenting mechanical bonding process and uncolored status to avoid reclassification
• Ensure fabric width exceeds 30 cm and plain weave structure; common pitfall is misdeclaring as colored leading to higher duties
