7019.19.70.00 - Fiberglass rubber reinforcing cord, made 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

This HTS category, 7019.19.70.00, specifically covers fiberglass rubber reinforcing cord. These cords are manufactured from continuous, electrically nonconductive fiberglass filaments with a diameter ranging from 9 to 11 microns. A key characteristic is their impregnation with a resorcinol formaldehyde latex treatment, which is essential for ensuring strong adhesion to various polymeric compounds. This treatment is crucial for the intended use of these cords as reinforcing elements.

This classification distinguishes itself from its sibling, 7019.19.30.00, which pertains to chopped strands exceeding 50 millimeters in length. Unlike chopped strands, the goods under 7019.19.70.00 are in the form of cords, indicating a continuous filament structure designed for reinforcement applications where tensile strength and adherence are paramount. The presence of the specific latex treatment further differentiates it from more general fiberglass materials.

As this is a leaf node within the HTS, there are no further subcategories. Classification within this code is determined by the precise physical and chemical attributes described: the filament diameter, the continuous nature of the filaments forming a cord, and the specific resorcinol formaldehyde latex impregnation for polymer adhesion. These detailed specifications ensure that only products meeting these exact criteria are classified under this heading.
