Glass fibres, mechanically bonded fabrics and closed woven fabrics, plain weave, of yarns, not coated or laminated (other than rovings).
Classification of fiberglass cloth (uncoated) under HS 7019.63
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.

Codes often confused with 7019.63
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
