U.S. imports of polyester filament yarn, single, untwisted or ≤50 turns/meter, not for retail sale (nesoi) (HS 540247) totaled $2.0M in July 2026, traded with 18 countries.
Importers of Polyester Filament Yarn, Single, Untwisted or ≤50 Turns/Meter, Not for Retail Sale (NESOI) paid $191K in duties in July 2026 — an effective duty rate of 14% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Polyester Filament Yarn, Single, Untwisted or ≤50 Turns/Meter, Not for Retail Sale (NESOI) imports of $2.0M in July 2026 ran 29% below the year-to-date monthly average of $2.8M.
Last updated: July 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.
