Importers of Cellulose Nitrates (Including Collodions) in Primary Forms paid $1.2M in duties in April 2026 — an effective duty rate of 15% on $7.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Cellulose Nitrates (Including Collodions) in Primary Forms imports of $9.0M in April 2026 ran 21% below the year-to-date monthly average of $11.4M.
Last updated: April 2026 dataCellulose nitrates — also known as nitrocellulose — are classified by nitrogen content into grades ranging from low-nitrogen lacquer-grade material used in coatings and printing inks to higher-nitrogen propellant-grade material subject to strict explosives regulations. Collodions, a solution of low-nitrogen cellulose nitrate in ether-alcohol, are included in this heading and have historical use in medical and photographic applications. Because cellulose nitrate is a flammable solid and, at higher nitrogen levels, an explosive precursor, imports are subject to DOT hazardous materials transport rules and may require ATF permits depending on the nitrogen content and intended use; importers should verify regulatory requirements before shipment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Lacquer-grade cellulose nitrate (typically below 12.6% nitrogen) is regulated primarily as a flammable solid under DOT rules and is widely used in coatings and inks. Higher nitrogen-content grades approach explosive classification and may require ATF licensing and additional import permits. Importers must confirm the nitrogen content from the manufacturer's certificate of analysis and consult a licensed customs broker and, where applicable, ATF before importing.
Cellulose nitrate in primary forms is typically traded as a dampened chip or flake (wetted with alcohol or water to reduce flammability risk), while collodion is a ready-to-use solution in ether-alcohol. Collodion is used in specialty medical applications such as wound sealants and in certain photographic processes, whereas chip-form nitrocellulose is the standard input for coatings, printing inks, and adhesives manufacturers.
