Last updated: September 2026 dataCoating or laminating plain-weave glass yarn fabrics with PTFE, silicone, acrylic, or other polymers transforms them into high-performance materials for architectural membranes, conveyor belting, release liners, and fire barriers. South Korea leads US supply under this heading — reflecting its advanced technical textile sector — followed by Mexico and Germany. The US schedule mirrors the uncoated heading's structure, with nine lines differentiating filament diameter, width, silica content, and color, making the coating or lamination step the primary classification gate between 701963 and 701964.

A coating or lamination must add a distinct layer of polymer or other material to the fabric surface — PTFE dispersion coating, silicone impregnation, or a bonded film laminate all qualify. Surface sizing or chemical treatments applied solely to improve fiber adhesion in composites generally do not constitute a coating for classification purposes. Manufacturer product data sheets specifying coating type, add-on weight, and process method are the standard supporting documents.
Yes, coated and uncoated plain-weave glass yarn fabrics are classified under separate headings (701964 versus 701963) and carry distinct tariff lines with potentially different duty rates. Importers should not assume the two headings are interchangeable — the coating step is a material change in the product's character, and misclassifying a coated fabric as uncoated (or vice versa) can result in duty underpayment or overpayment. Consulting a licensed customs broker is advisable when the coating's nature or thickness is ambiguous.
