7019.61.30.00 - 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 specific types of fiberglass tire cord fabric. The key characteristics defining goods under this subheading are that they are woven from continuous fiberglass filaments with diameters ranging from 9 to 11 microns. Furthermore, these fabrics must be treated with a resorcinol formaldehyde latex impregnation, specifically designed to enhance adhesion to polymeric compounds. This treatment is crucial for their intended use in the reinforcement of tires.

This category is distinguished from its sibling, 7019.61.40, which covers "Other" closed woven fabrics of rovings. While both fall under mechanically bonded fabrics and closed woven fabrics of rovings that are not colored, the distinguishing factor for 7019.61.30.00 lies in the precise filament diameter specifications and the mandatory resorcinol formaldehyde latex treatment for tire cord applications.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification at this level is therefore determined by meeting all the specific material and treatment criteria outlined in the description. Examples of goods classified here would be specialized fabrics specifically manufactured for use as reinforcing elements within tire structures, exhibiting the defined filament dimensions and impregnation.
