U.S. imports of open glass fabrics, chemically bonded, nesoi (HS 701973) totaled $149K in April 2026, traded with 13 countries.
Last updated: April 2026 dataChemically bonded open-weave glass fabrics combine the open mesh structure used in reinforcement and filtration applications with a chemical binder that stabilizes the weave geometry. The four US tariff lines (7019730000, 7019735100, 7019739010, 7019739090) separate tire-cord constructions from general open-weave goods and further split by silica content threshold. China is the primary supplier, with Japan and Canada also notable sources. Importers sourcing from China should assess Section 301 applicability, while Canadian-origin goods may benefit from USMCA treatment subject to applicable rules of origin.

Open-weave fabrics (701973) have visible interstices between yarns, making them suitable for mesh reinforcement, window screening, and filtration. Closed-weave fabrics (701972) have a tighter construction used for electrical insulation and structural composites. The distinction is structural and must be supported by technical specifications; when the weave geometry is borderline, a CBP binding ruling can provide certainty.
Japan is a secondary but notable supplier under this heading, typically providing specialty or high-performance grades — such as fine-filament or high-silica constructions — where Japanese manufacturers hold technical advantages. Lead times and minimum order quantities from Japanese suppliers tend to differ from those of high-volume Chinese producers, which can affect inventory planning for US buyers.
