7019.64.05.00 - 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, 7019.64.05.00, specifically classifies fiberglass tire cord that meets a precise set of technical specifications. These cords are woven from continuous glass filaments ranging from 9 to 11 microns in diameter, are electrically nonconductive, and have undergone an impregnation process with resorcinol formaldehyde latex. This treatment is crucial as it enhances adhesion to polymeric compounds, a characteristic essential for their primary application in tire manufacturing.

Distinguishing this category from its sibling, 7019.64.15 ("Other"), is the highly specific nature of the product described. While 7019.64.15 would encompass other mechanically bonded, closed woven fiberglass fabrics not meeting the filament diameter, conductivity, or specific impregnation treatment detailed here, this particular code is reserved for the specially treated tire cord. The "05.00" designation signifies the granular specificity of the classification.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification under 7019.64.05.00 hinges entirely on the precise fulfillment of all criteria outlined in the description. Importers should ensure that their product aligns with the specified filament diameter range, non-conductive property, and the particular resorcinol formaldehyde latex treatment for optimal adhesion to polymeric materials.
