About HS Code 701913

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.

Products Under This Code

Glass fiber sewing thread, woven glass fabrics, braided glass sleeves, glass fiber filter cloth, electrical insulation tapes, high-temperature resistant textiles, glass fiber reinforcement for circuit boards

Real World Examples

Vitrulan glass yarns, Ahlstrom-Munksjö glass fiber textiles, Porcher Industries glass yarns, SGL Carbon glass fiber fabrics

Common Misclassification

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.
