U.S. imports of other single artificial filament yarn (not for retail sale, nesoi) (HS 540339) totaled $525 in June 2026, traded with 6 countries.
Other Single Artificial Filament Yarn (Not for Retail Sale, NESOI) imports of $525 in June 2026 ran 96% below the year-to-date monthly average of $15K.
Artificial filament yarns that are neither viscose rayon nor cellulose acetate — including cuprammonium rayon (Bemberg) and lyocell filament — are captured in this residual single-yarn heading, which also encompasses textured artificial filament constructions. The US schedule distinguishes textured single yarn (5403391000) from other constructions, with further subdivision by twist level and decitex for unspecified artificial filaments (5403399020 and 5403399040). Japan leads US imports under this heading, a reflection of its specialty in cuprammonium and other premium regenerated-fiber yarns, with Pakistan and Italy also among the top sources. Classification hinges on confirming the fiber's generic name, as any yarn that qualifies as viscose or acetate must be redirected to the named-fiber headings.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Lyocell is a regenerated cellulosic fiber distinct from viscose rayon and cellulose acetate, so single lyocell filament yarn not for retail sale would fall under the NESOI provision of heading 5403.39 rather than the named-fiber subheadings. Importers should confirm the fiber's generic name per FTC fiber identification rules and retain mill documentation to support the classification.
Tariff line 5403391000 specifically covers textured single artificial filament yarn — yarn that has been processed (e.g., by false-twist, air-jet, or stuffer-box methods) to introduce bulk, stretch, or crimp. Textured yarn commands different end-use applications (stretch linings, knit fabrics) and may carry a different duty rate than untextured constructions, so the processing method must be documented at entry.
