Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If colored with dyes or pigments
Colored glass fiber fabrics shift to 7019.66.20, separating them from uncolored 'not colored' category.
If width not exceeding 30 cm
Narrower fabrics ≤30 cm wide fall under different width subheading regardless of weight or weave.
If sold as woven fabric of rovings rather than filaments
Roving-based weaves classify under 7019.40, distinct from filament yarn weaves in 7019.66.

Import Tips & Compliance
• Verify filament tex (≤136) and exact weight ≤185 g/m² via lab testing to avoid reclassification to higher weight subheadings
• Provide mill test certificates confirming uncolored status and mechanical bonding process for customs clearance
• Ensure fabric width documentation >30 cm; common pitfall is mismeasurement leading to 7019.66.20 classification
