HS Code 7019.13 – Glass fibres; (including glass wool), yarns and slivers
HS code 7019.13 is the 6-digit subheading for glass fibres, (including glass wool), yarns and slivers. It is used for glass fiber sewing thread, woven glass fabrics, braided glass sleeves, glass fiber filter cloth and electrical insulation tapes.
What HS 7019.13 covers
This classification covers glass fibers, including glass wool, processed into yarns and slivers. Yarns are continuous strands of twisted fibers, suitable for weaving, knitting, or braiding, while slivers are untwisted bundles of continuous fibers, often used as an intermediate for spinning. These forms of glass fiber are highly valued for their high strength-to-weight ratio, excellent thermal stability, and superior electrical insulation properties, making them essential in technical textiles and specialized industrial applications. Importers include manufacturers of fire-resistant fabrics, electrical insulation materials, filtration media, and high-performance sewing threads. Exporters are typically textile or specialized glass fiber producers with expertise in fiber processing. Key considerations for trade include yarn count, twist level, and the specific sizing applied for optimal processing and end-use performance in demanding environments.

Codes often confused with 7019.13
Common mistake. Can be confused with 701912 (rovings) if the distinction between a continuous bundle (roving) and a twisted, spun strand (yarn) is not clear. Also, 5903 (textile fabrics impregnated, coated, covered, or laminated with plastics) if the glass yarn is already incorporated into a coated fabric.
Top exporters and importers of HS code 701913, 2025
In 2025, the largest exporter of HS code 701913 in UN Comtrade data was Taiwan, with about 24% of world exports; the largest importer in UN Comtrade data was the United States, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
