U.S. imports of woven fabrics of polyester staple fibers, under 85%, mixed with other fibers (nesoi) (HS 551519) totaled $406K in April 2026, traded with 27 countries.
Last updated: April 2026 dataPolyester staple fiber woven fabrics blended with fibers not covered by the more specific headings — such as cotton, linen, or other natural fibers other than wool — fall into this residual category when polyester content is under 85% by weight. India and China are the leading US suppliers, reflecting broad production capacity for commodity and specialty polyester blends across South and East Asia. The US schedule spans a wide range of construction types, from blue denim (5515190010) and duck (5515190035) to satin/twill weaves (5515190040), underscoring the diverse end-use applications. Importers should confirm that the blending fiber does not qualify for a more specific heading before defaulting to this NESOI classification.

Chapter classification depends on which fiber predominates by weight. If polyester staple fibers are the greatest single fiber component by weight (even if under 85%), the fabric classifies in Chapter 55 under the polyester headings. If cotton predominates, the fabric would shift to Chapter 52. When fiber weights are close, a precise laboratory analysis is essential to determine the correct chapter.
Both duck (5515190035) and satin/twill weave (5515190040) constructions fall within the same heading but are assigned distinct 10-digit tariff lines. While the duty treatment may be the same, correct line selection matters for quota monitoring, statistical reporting, and any future trade-remedy applicability. The weave structure should be confirmed from the mill's technical data sheet.
