Last updated: April 2026 dataCellulose nitrates — also known as nitrocellulose — are energetic polymers used in lacquers, printing inks, leather finishes, and propellant formulations, and their import is subject to hazardous-materials transport regulations that add compliance complexity beyond standard customs clearance. Brazil is the leading US supplier under this heading, followed by the Czech Republic and China; Brazilian producers have built significant nitrocellulose capacity serving the coatings and ink industries. Importers must coordinate with carriers on UN hazard classification and packaging requirements, as nitrocellulose is regulated as a flammable solid under DOT and IATA rules regardless of its end use.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Cellulose nitrate is classified as a flammable solid under DOT regulations (49 CFR) and must be shipped in UN-approved packaging with proper hazard labels and a compliant shipping declaration. The nitrogen content and moisture/plasticizer level determine the specific UN number and packing group, so the supplier's safety data sheet and certificate of analysis are essential for preparing accurate shipping documents.
For HTS purposes, all cellulose nitrates in primary forms — regardless of nitrogen content — are classified under the single line 3912200000. However, nitrogen content is critical for DOT hazard classification and for determining whether the product qualifies as a propellant-grade material subject to additional ATF or export-control review by the country of origin.
