7019.72.30.00 - 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 category specifically covers fiberglass tire cord fabric that is woven from continuous fiberglass filaments. Key characteristics defining this classification include filament diameters ranging from 9 to 11 microns and the presence of a resorcinol formaldehyde latex treatment. This impregnation is crucial for ensuring the fabric's adhesion to polymeric compounds, a primary functional requirement for its use in tire reinforcement.

This specific designation distinguishes itself from its sibling category, HTS 7019.72.40 "Other," by the explicit mention of the fiberglass tire cord fabric and its specific treatment for tire applications. While other woven fiberglass fabrics might exist, this code is narrowly tailored to the composite material designed for the demanding performance requirements of the automotive tire industry, emphasizing its intended end-use and the specialized treatment it undergoes.

As this is a leaf node within the HTS structure, there are no further subcategories to detail. Therefore, classification under 7019.72.30.00 is definitive for qualifying fiberglass tire cord fabric meeting the described specifications and treatment. Importers should ensure their product precisely aligns with the filament diameter, weaving, and chemical treatment described to ensure accurate customs declaration.
