U.S. imports of polyester filament yarn, single, twisted over 50 turns/meter, not for retail sale (HS 540252) totaled $127K in July 2026, traded with 20 countries.
Last updated: July 2026 dataPolyester single yarn with a twist exceeding 50 turns per meter serves crêpe fabric, fine woven apparel, and specialty textile markets where high-twist geometry is a functional specification rather than a processing artifact. Three 10-digit lines subdivide the heading: 5402520000 for the general category, 5402521000 for yarns in the 75–80 decitex range, and 5402529000 for other high-twist polyester filament yarns not covered by the decitex-specific line. Malaysia leads US imports under this heading, followed by Mexico and Switzerland — an unusual supplier mix that reflects both regional textile manufacturing and specialty yarn production in Europe. The decitex-band line (5402521000) mirrors a similar split seen in the low-twist polyester heading, so importers familiar with that structure will recognize the classification logic.

The 75–80 decitex band (line 5402521000) corresponds to a fine-denier range commonly used in lightweight woven apparel and crêpe fabrics, where duty treatment or trade-remedy scope may differ from coarser or finer yarns. The same decitex window appears in the low-twist polyester heading, reflecting a consistent US tariff-schedule approach to this commercially significant fineness range. Importers should measure linear density carefully, as yarns just outside the band fall into 5402529000.
Manufacturer's technical data sheets, mill test certificates, or independent laboratory reports using standardized twist-count methods are the most reliable supporting documents. Because the 50-turns-per-meter threshold is the dividing line between two distinct HTS headings with potentially different duty rates, CBP may request physical samples for testing if the documentation is ambiguous.
