U.S. imports of nonplasticized cellulose acetates in primary forms (HS 391211) totaled $1.1M in April 2026, traded with 9 countries.
Last updated: April 2026 dataNonplasticized cellulose acetate in primary forms is the key feedstock for cigarette filter tow, optical film, and specialty membranes, and its classification as nonplasticized distinguishes it from the softer, more flexible grades used in molding compounds. China and India are the leading US suppliers under this heading, with France also a significant source; Chinese-origin imports are subject to Section 301 tariffs, a factor that has elevated interest in Indian and European supply. The single US tariff line (3912110000) covers all nonplasticized grades regardless of acetyl content, so degree of substitution is a specification rather than a classification variable.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Cellulose triacetate (CTA), with an acetyl content corresponding to near-complete substitution (typically above about 92% acetylation), is classified separately under heading 3912 as well, but in a distinct subheading. Standard cellulose diacetate with lower acetyl content falls under 3912110000 when nonplasticized. Importers should obtain a certificate of analysis specifying degree of substitution to support the correct classification.
Because Chinese-origin imports carry Section 301 tariffs, buyers have increasingly evaluated Indian producers and European suppliers as alternative sources. India has expanded capacity in cellulose acetate flake, and its growing share in US imports reflects both competitive pricing and the desire to reduce Section 301 cost exposure.
