U.S. imports of single viscose rayon filament yarn, untwisted or low-twist (not for retail sale) (HS 540331) totaled $8.8M in June 2026, traded with 8 countries.
Importers of Single Viscose Rayon Filament Yarn, Untwisted or Low-Twist (Not for Retail Sale) paid $1.2M in duties in June 2026 — an effective duty rate of 20% on $6.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Single Viscose Rayon Filament Yarn, Untwisted or Low-Twist (Not for Retail Sale) imports of $8.8M in June 2026 ran 48% above the year-to-date monthly average of $5.9M.
Single viscose rayon filament yarn with a twist of no more than 120 turns per meter occupies a broad middle ground between flat (zero-twist) weaving yarn and high-twist crepe yarn, making it a versatile input for apparel linings, dress fabrics, and lightweight woven textiles. The US schedule distinguishes by twist level and filament count: untwisted or below 5 turns/meter (5403310020) and multifilament constructions twisted between 5 and 120 turns/meter (5403310040). Germany leads US imports under this heading, with India and Indonesia also significant sources. Mexico's presence among top suppliers means a portion of trade may benefit from USMCA preferential treatment, though origin qualification depends on fiber-forward or yarn-forward rules.

Heading 5403.31 covers single viscose rayon yarn twisted at or below 120 turns/meter, while 5403.32 captures yarn twisted above that threshold. The turns-per-meter count must be verified from the mill's technical data sheet or by laboratory testing; the distinction affects both the applicable HTS line and, in some cases, the applicable duty rate.
A mill certificate or technical data sheet confirming fiber composition (viscose rayon), filament count (mono vs. multi), twist direction, and turns-per-meter is standard. Country-of-origin documentation and, where applicable, a certificate of origin for preferential tariff claims should accompany the commercial invoice. Consult a licensed customs broker for complex origin or classification questions.
