7019.65.51.00 - 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 classification, 7019.65.51.00, specifically covers fiberglass tire cord that is woven from continuous glass filaments. Key characteristics include filament diameters ranging from 9 to 11 microns and an impregnation with a resorcinol formaldehyde latex treatment. This treatment is crucial for ensuring adhesion to polymeric compounds, a requirement for its intended use in tire construction. The material is classified under mechanically bonded fabrics and is further defined as an open woven fabric with a width not exceeding 30 cm.

Distinguishing this subcategory from its sibling, 7019.65.90 ("Other"), is its precise specification of the fiberglass tire cord and its treatment. While the "Other" category would encompass mechanically bonded, open-woven fabrics of fiberglass not exceeding 30 cm in width that do not meet the specific criteria of 7019.65.51.00, this particular subcategory is reserved for the specialized tire cord. The explicit mention of filament size, construction, and the adhesion treatment are the defining elements for classification here.

As this is a leaf node, there are no further subcategories. The classification ends at this specific product description, meaning any goods meeting all the outlined physical and functional criteria will fall directly under this HTS code. Therefore, the focus for classification purposes is on verifying the presence of woven fiberglass filaments within the specified diameter range and the application of the resorcinol formaldehyde latex treatment for adhesion to polymeric compounds, in addition to the width constraint.
