7019.72.05.00 - 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 specifically covers woven fiberglass fabrics that are manufactured from continuous fiberglass filaments with a diameter ranging from 9 to 11 microns. A key characteristic of these fabrics is their electrical non-conductivity and their impregnation with a resorcinol formaldehyde latex treatment, designed to enhance adhesion with polymeric compounds. These treated fabrics are commonly employed in the reinforcement of tires, often referred to as tire cord fabric.

Distinguishing this category from its sibling, 7019.72.15.00, relies on the specific manufacturing and treatment of the fiberglass fabric. While both fall under "Other closed fabrics" of a width not exceeding 30 cm, 7019.72.05.00 is precisely defined by the filament diameter and the resorcinol formaldehyde latex treatment for specific adhesive properties. The sibling category, "Other," would encompass other types of woven fiberglass fabrics meeting the general criteria but lacking these specific defining characteristics.

As a leaf node, this classification represents the most granular level of detail for this particular type of fiberglass tire cord fabric. Therefore, instead of introducing subcategories, classification professionals should pay close attention to the precise filament diameter specifications and the presence and type of chemical treatment mentioned in the description to ensure correct tariff placement. Any deviation in these parameters would likely lead to classification under a different HTS code.
