Uncolored Closed Woven Roving Glass Fabric 800 gsm
This is a heavy-weight, closed woven fabric made from uncolored glass fiber rovings, typically used in industrial composite reinforcement for boat hulls and wind turbine blades. It falls under HTS 7019.61.40.60 as a mechanically bonded, closed woven fabric of rovings that is not colored and classified as 'other'. The tight weave structure provides high strength and minimal fiber exposure.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the fabric contains any coloring or tinting
Colored glass fiber fabrics shift to 7019.62 series, separating by pigmentation regardless of weave.
If chemically bonded rather than mechanically bonded
Chemically bonded nonwoven glass mats use binders and fall under different subheading.
If coated or laminated with plastics for textile use
Plastic-coated glass fabrics are classified as textile-covered materials in Chapter 59.

Import Tips & Compliance
• Verify mechanical bonding process documentation to distinguish from chemically bonded nonwovens under 7019.40
• Provide weave pattern specs and roving tex size to confirm closed woven classification vs. open fabrics
• Ensure no coloring agents present; test for compliance to avoid reclassification to colored subheadings
