HS Code for Fiberglass cloth (uncoated)

Fiberglass cloth (uncoated) is classified under HS code 7019.63. This classification is determined by the General Rules of Interpretation (GRI), specifically GRI 1 and GRI 6, which dictate that classification is governed by the terms of the headings and any relative section or chapter notes. Heading 7019 covers glass fibers and articles thereof. Subheading 7019.63 specifically identifies mechanically bonded fabrics and closed woven fabrics of a plain weave, constructed from yarns, which have not been coated or laminated. The "plain weave" designation is critical; it refers to a textile weave where the threads are interlaced in an alternating over-and-under pattern. Because these fabrics are "uncoated," they lack any secondary polymer, silicone, or PTFE layers that would otherwise shift the classification to 7019.64. These materials are valued for their high tensile strength, dimensional stability, and resistance to high temperatures, making them essential in industrial filtration and reinforcement. The absence of chemical treatments that would alter the surface properties of the glass fibers ensures they remain within this specific subheading.

Common Misclassification

This product is frequently confused with HS code 7019.64, which covers woven fabrics that are coated or laminated. If the cloth has been treated with silicone, polyurethane, or acrylic to enhance durability or water resistance, it must be moved to 7019.64. Additionally, it is sometimes confused with 7019.61, which covers fabrics made of rovings rather than yarns. The distinction lies in the twist of the fiber; yarns are twisted, whereas rovings are untwisted strands.
