7019.72.70.00 - 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 code, 7019.72.70.00, specifically classifies fiberglass tire cord fabric. The defining characteristics for this classification are that the fabric is woven from continuous glass filaments, typically between 9 and 11 microns in diameter, and is treated with a resorcinol formaldehyde latex. This treatment is crucial for ensuring adhesion to polymeric compounds, making it suitable for use in tire construction. The "electrically nonconductive" aspect further refines the material's application.

At this level, the distinction from sibling categories is important. The primary sibling, 7019.72.90, covers "Other" closed fabrics within this subcategory. This implies that 7019.72.70.00 is for a more specific type of chemically bonded fiberglass fabric, not merely any other closed fabric falling under the broader description. The specificity of the filament diameter, non-conductive property, and the particular latex treatment are the key differentiators.

As this is a leaf node, there are no further subcategories. Therefore, the focus shifts to providing clarity on the scope of this specific classification. Goods classified here are exclusively fiberglass tire cord fabrics that meet all the aforementioned technical specifications. Any fiberglass fabric that deviates from these precise criteria, for instance, having a different filament diameter, lacking the specific latex treatment, or not intended for tire cord applications, would likely fall under a different HTS classification, most probably the "Other" category at this level or a higher level depending on the extent of the deviation.
