U.S. imports of cellulose & chemical derivatives n.e.s. in primary forms (SITC 57559) totaled $11.9M in April 2026, traded with 28 countries.
Importers of Cellulose & Chemical Derivatives N.E.S. in Primary Forms paid $670K in duties in April 2026 — an effective duty rate of 5.8% on $11.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Cellulose & Chemical Derivatives N.E.S. in Primary Forms imports of $11.9M in April 2026 ran 16% above the year-to-date monthly average of $10.2M.
Last updated: April 2026 dataCellulose derivatives not elsewhere specified — such as cellulose acetate, cellulose nitrate (nitrocellulose), and cellulose xanthate — occupy a residual but commercially significant category within the broader cellulose chemicals trade. Nitrocellulose, used in lacquers, printing inks, and propellants, carries additional regulatory scrutiny as a flammable solid under DOT hazmat rules and may require special import permits depending on concentration and intended use. Cellulose acetate, a primary input for cigarette filter tow and optical films, is widely traded and subject to standard chemical tariff treatment. Accurate classification requires distinguishing the specific derivative from cellulose ethers (SITC 57554) and regenerated cellulose.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Cellulose ethers (SITC 57554) involve substitution of hydroxyl groups with ether linkages (e.g., methyl, ethyl, carboxymethyl groups), while this NES category captures ester-type derivatives such as cellulose acetate and nitrate, as well as other chemically modified celluloses not classifiable elsewhere. The specific chemical bond type — ether versus ester — is the primary classification determinant.
Nitrocellulose is regulated as a flammable solid under US DOT hazardous materials rules, requiring proper labeling, packaging, and shipping documentation. Depending on nitrogen content and intended use (e.g., propellant grade), additional permits or agency notifications may apply. Consult a licensed customs broker or freight forwarder experienced in hazmat chemicals before importing.
