7019.63.05.00 - Fiberglass tire cord 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 category specifically covers fiberglass tire cord that is woven from continuous glass filaments. The filaments must fall within a diameter range of 9 to 11 microns, and the woven fabric is treated with a resorcinol formaldehyde latex compound to ensure adhesion with polymeric materials. This treatment is crucial for its intended use in reinforcing tires.

This classification is distinct from its sibling category, 7019.63.15 ("Other"), which would encompass mechanically bonded fiberglass fabrics that do not meet the specific criteria outlined for tire cord. The presence of the resorcinol formaldehyde latex treatment for polymeric adhesion and the precise filament diameter are key differentiating factors.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, the focus for classification at this level is solely on the precise material composition, physical characteristics (filament diameter, weave type), and specific functional treatment (latex impregnation for adhesion) of the fiberglass woven fabric. This ensures that only goods meeting all these stringent requirements are classified under 7019.63.05.00.
