Chemically Bonded Fiberglass Roofing Mat
A non-woven, chemically bonded fabric made from colorless glass fibers, designed for use as a reinforcement mat in asphalt shingle roofing. It falls under HTS 7019.72.40.60 as 'other' closed chemically bonded glass fiber fabrics that are not colored. This classification applies to mats with a closed structure formed by chemical binders rather than weaving or needling.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If open structure fabric
Open chemically bonded glass fiber fabrics are classified separately from closed ones in the same heading.
If needled or stitched
Mechanically bonded glass fiber felts or mats fall under heading 6808, not chemically bonded in 7019.
If sold as woven fabric
Woven glass fiber fabrics are classified in 7019.40, regardless of reinforcement use.

Import Tips & Compliance
• Verify the chemical binder composition and fiber content to confirm classification under chemically bonded mats; provide lab test reports for silica content if challenged
• Ensure documentation distinguishes it from chopped strand mats or needled felts
• Common pitfall: misclassifying as textile nonwovens under Chapter 59
