Heavyweight Fiberglass Insulation Mat
A mechanically bonded non-woven fiberglass fabric weighing over 215 g/m² with filament diameters of 7-13 microns, used for thermal and acoustic insulation in walls and attics. It falls under HTS 7019.69.40.21 due to its specific weight, filament size, and non-colored status as a glass fiber fabric. This mat is produced by bonding glass fibers without weaving, meeting the chapter's definition for such materials.

Import Tips & Compliance
• Verify filament diameter and weight via lab testing to confirm classification under 7019.69.40.21; deviations may shift to other subheadings
• Provide mill test certificates documenting glass composition and bonding method to avoid misclassification as woven fabrics
• Ensure proper labeling for industrial use to prevent reclassification as consumer goods under Chapter 94
