SITCSection 5
U.S. exports of non-plasticised cellulose acetates in primary forms (SITC 57551) totaled $35.4M in July 2026.
Importers of Non-Plasticised Cellulose Acetates in Primary Forms paid $7K in duties in July 2026 — an effective duty rate of 13% on $57K in dutiable value, based on actual customs collections rather than the published tariff schedule. Non-Plasticised Cellulose Acetates in Primary Forms imports of $57K in July 2026 ran 85% below the year-to-date monthly average of $381K.
Last updated: July 2026 dataNon-plasticised cellulose acetate — supplied as flake, powder, or granule — is the primary feedstock for cigarette filter tow, optical film, and specialty textile fibers, making it a strategically important intermediate in both the tobacco and display-panel supply chains. The absence of plasticiser is the defining characteristic that separates this heading from plasticised grades and governs its downstream processability; filter-tow producers, for example, require tightly controlled acetyl content and viscosity specifications. Importers should confirm degree of substitution (DS) and acetyl content in the certificate of analysis, as these parameters directly affect classification and end-use suitability.

Acetyl content (degree of substitution), inherent viscosity, and moisture content are the primary quality parameters. Filter-tow manufacturers typically specify a narrow DS range around 2.4–2.5 and tight viscosity tolerances; deviations can cause processing problems in the spinning and crimping stages.
The key distinction is the absence of any added plasticiser such as triacetin or diethyl phthalate. Importers should provide a certificate of analysis confirming zero plasticiser content; if a plasticiser is present at any level, the product falls under the plasticised cellulose acetate heading instead.
