U.S. exports of Single Cellulose Acetate Filament Yarn (Not for Retail Sale) (HS 540333) totaled $15.1M in August 2026.
Single Cellulose Acetate Filament Yarn (Not for Retail Sale) imports of $19K in August 2026 ran 89% below the year-to-date monthly average of $174K.
Last updated: August 2026 dataCellulose acetate filament yarn — derived from wood pulp acetylation rather than petroleum — offers a silk-like luster and soft hand that synthetic fibers replicate poorly, making it a preferred input for luxury linings, cigarette filter tow precursors, and high-end woven apparel. The US schedule subdivides by filament count and twist: untwisted or below 5 turns/meter (5403330020) and multifilament constructions above 5 turns/meter with finer decitex (5403330040). Japan and Italy are the leading suppliers, reflecting the concentration of acetate yarn production among a small number of specialty chemical-fiber producers. Canada's presence among top sources means some trade may qualify for USMCA preferential treatment, subject to applicable textile rules of origin.

The HTS treats them as distinct fiber types within Chapter 54. Acetate yarn falls under heading 5403.33 (single) or 5403.42 (multiple/cabled), while viscose rayon occupies headings 5403.31–5403.32 and 5403.41. The chemical distinction — acetylation of cellulose versus xanthate regeneration — must be confirmed by fiber content testing or mill certification; misidentification between the two is a documented classification error.
The US 10-digit breakdown at 5403330040 specifically targets multifilament acetate yarn twisted at or above 5 turns/meter with a linear density below 67 decitex. Yarn at or above 67 decitex in the same twist range falls under the broader 5403330020 line. Importers should confirm decitex from the mill's technical specification to select the correct 10-digit line.
