Importers of Closed Plain-Weave Glass Yarn Fabrics, Uncoated paid $281K in duties in July 2026 — an effective duty rate of 20% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Closed Plain-Weave Glass Yarn Fabrics, Uncoated imports of $1.7M in July 2026 ran 34% above the year-to-date monthly average of $1.2M.
Last updated: July 2026 dataPlain-weave fabrics woven from glass yarns without any coating or lamination are the standard substrate for printed circuit board laminates (notably E-glass style 7628), electrical insulation, and architectural mesh. The US schedule distinguishes these fabrics by filament diameter, width, silica content, and color across nine 10-digit lines, with silica-content lines (7019634030 for >93% silica; 7019634060 for ≤93%) capturing high-performance quartz and specialty glass fabrics. China dominates supply, with Canada and Germany also significant.

Standard E-glass PCB fabrics (typically 9–11 micron filament diameter, uncolored, width over 30 cm) generally fall under the mechanically bonded, uncolored, wide-format lines within 701963. However, the specific 10-digit line depends on filament diameter and whether the fabric is silica-based. Importers should obtain mill certifications confirming filament diameter and silica content, and consider a binding ruling for high-volume PCB substrate imports given the multiple available lines.
Fabrics woven from silica filaments with silica content exceeding 93% (line 7019634030) are high-purity quartz or fused-silica fabrics used in aerospace radomes and high-temperature electrical insulation — distinct from standard E-glass or S-glass fabrics. The ≤93% silica line (7019634060) captures lower-purity specialty glasses. Chemical analysis documentation from the manufacturer is the standard method for supporting the correct classification.
