7019.69.30.00 - 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, 7019.69.30.00, specifically covers mechanically bonded fabrics of glass fibers that are neither colored nor treated in a way that would alter their fundamental nature for broader applications. The defining characteristic here is the fabric's construction from continuous fiberglass filaments, falling within a precise diameter range of 9 to 11 microns. Crucially, these fabrics undergo a specific impregnation process with a resorcinol formaldehyde latex treatment. This treatment is designed to enhance adhesion to polymeric compounds, a key attribute for their intended use, particularly in applications such as tire reinforcement where strong bonding is essential.

This subcategory is distinguished from its sibling, 7019.69.40, which represents "other" mechanically bonded fiberglass fabrics that do not meet the specific criteria of this particular code. The presence of the resorcinol formaldehyde latex treatment for adhesion to polymeric compounds is the primary distinguishing factor, indicating a specialized application rather than a general-purpose fabric.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification of goods under this code rests entirely on meeting all the specified criteria: mechanically bonded fiberglass fabric, composed of continuous filaments within the defined micron range, and specifically treated with resorcinol formaldehyde latex for polymeric compound adhesion, and not being colored. Examples include fiberglass fabrics intended for use in the manufacturing of tires or other rubberized composite goods where the enhanced adhesion is a critical performance requirement.
