Classification of plain weave fiberglass fabric under HS 7019.63
Plain weave fiberglass fabric is classified under HS code 7019.63. This classification is part of the significant 2022 restructuring of heading 7019, which covers glass fibers and articles thereof. Subheading 7019.63 specifically addresses woven fabrics of yarns that are not coated or laminated and are constructed using a plain weave pattern. In a plain weave, the warp and weft yarns cross each other at right angles in a simple over-under pattern, providing high dimensional stability and porosity. To qualify for this code, the fabric must be made of glass fiber yarns rather than rovings (which are classified under 7019.61). The classification is strictly based on the material composition (glass), the manufacturing method (woven), the specific weave type (plain), and the absence of secondary treatments like lamination or heavy coatings. These fabrics are essential in composite reinforcements, filtration, and thermal insulation applications due to their high tensile strength and resistance to heat.

Codes often confused with 7019.63
Common mistake. This product is often misclassified under 7019.61 if the fabric is made of rovings instead of yarns. It is also frequently confused with 7019.69, which covers other woven fabrics, including those with complex weaves (like twill or satin) or those that have been coated or laminated. If the fiberglass fabric is impregnated with resin or bonded to a plastic film, it must be moved to 7019.69 or 7019.90 depending on the degree of processing. Furthermore, if the fabric is made of glass wool rather than continuous fibers, different subheadings apply.

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).
