7019.61.70.00 - Fiberglass tire cord fabric woven from electrically nonconductive continuous fiberglass filaments 9 microns in diameter to 11 microns in diameter and impregnated with resorcinol formaldehyde latex treatment for adhesion to polymeric compounds (622)

This HTS classification covers specifically woven fiberglass tire cord fabrics. The defining characteristics include their construction from continuous fiberglass filaments with a diameter ranging from 9 to 11 microns, which are electrically nonconductive. Crucially, these fabrics are impregnated with a resorcinol formaldehyde latex treatment designed to enhance adhesion with polymeric compounds, a vital feature for their intended application in tire manufacturing.

Within the broader category of mechanically bonded fabrics, this subheading distinguishes itself from its sibling, 7019.61.90 (Other), by focusing on fabrics that are *colored*. While both fall under closed woven fabrics of rovings, the presence of coloring is the key differentiator. This implies that the fiberglass tire cord fabric classified under 7019.61.70.00 will exhibit a specific color imparted during its manufacturing process.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level requires careful consideration of the material (fiberglass), the construction method (woven from rovings, mechanically bonded), the specific treatment (resorcinol formaldehyde latex), and the presence of coloring. The precise specifications regarding filament diameter and impregnation are essential for accurate classification.
