Resorcinol-Formaldehyde Impregnated Fiberglass Tire Cord Fabric from Canada
This closed woven plain weave fabric is made from electrically nonconductive continuous fiberglass filaments measuring 9-11 microns in diameter, colored, and specifically impregnated with resorcinol formaldehyde latex (RFL) treatment to enhance adhesion to rubber compounds in tire manufacturing. It falls under HTS 7019.63.70.00 due to its precise filament size, weave type, nonconductive properties, coloring, and RFL impregnation tailored for tire cord applications. The mechanical bonding and lack of coating or lamination further confirm this classification.

Import Tips
• Verify filament diameter (9-11 microns) and RFL impregnation via lab testing to avoid reclassification; provide manufacturer specs confirming nonconductive continuous filaments and plain weave structure
• Ensure documentation includes tire cord end-use declaration to prevent misfiling under general glass fabrics
