U.S. imports of Polyester Filament Yarn, Single, Untwisted or ≤50 Turns/Meter, Not for Retail Sale (NESOI) (HS 540247) totaled $2.5M in September 2026, imported from 19 countries.
Importers of Polyester Filament Yarn, Single, Untwisted or ≤50 Turns/Meter, Not for Retail Sale (NESOI) paid $327K in duties in September 2026, an average duty rate of 16.83% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: September 2026 dataNon-partially-oriented polyester filament yarn at low twist — covering monofilament and multifilament constructions from untwisted through 50 turns per meter — is a foundational input for woven and knit fabrics, industrial textiles, and technical applications. The US tariff schedule subdivides this heading into six 10-digit lines (5402470020, 5402470040, 5402471020, 5402471040, 5402479020, 5402479040) distinguishing monofilament from multifilament, elastomeric from non-elastomeric, and a specific decitex band (75–80 decitex). South Korea and Thailand are the leading US suppliers, with Vietnam and Japan also significant sources. Antidumping orders on polyester filament yarn from certain origins remain a compliance consideration for buyers.

The 5402471000-series lines apply to yarns measuring between 75 and less than 80 decitex, with further splits for elastomeric versus non-elastomeric constructions. Yarns outside that decitex band fall into the 5402479000-series, which similarly separates monofilament (untwisted or ≤5 turns/m) from multifilament with twist between 5 and 50 turns/m. Accurate decitex measurement and elastomeric characterization are therefore essential for correct line-level classification.
CBP may request laboratory test results or manufacturer's technical data sheets confirming turns-per-meter measurements, since the boundary at 5 turns/m and the ceiling at 50 turns/m each determine the applicable 10-digit line. Mill certificates or third-party textile testing reports (e.g., ASTM or ISO twist-count methods) are commonly used as supporting documentation at entry.
