SITCSection 5
U.S. imports of acetals, hemiacetals & their halogenated, sulfonated, nitrated or nitrosated derivatives (SITC 51612) totaled $699K in July 2026, traded with 11 countries.
Importers of Acetals, Hemiacetals & Their Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives paid $91K in duties in July 2026 — an effective duty rate of 19% on $482K in dutiable value, based on actual customs collections rather than the published tariff schedule. Acetals, Hemiacetals & Their Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives imports of $699K in July 2026 ran 22% below the year-to-date monthly average of $893K.
Last updated: July 2026 dataAcetals and hemiacetals serve as key intermediates and solvents in fragrance, flavor, and resin manufacturing, with their derivatized forms — halogenated, sulfonated, nitrated, or nitrosated — finding use in specialty chemical synthesis. Classification within this SITC heading turns on whether the compound carries additional oxygen functionality and the nature of any derivative substitution, distinctions that can shift a product across multiple tariff lines. Industrial buyers sourcing these compounds for polymer or coating applications should verify the precise chemical identity to ensure correct classification.

Basic heading 51612 · $699K of $28.9B
An acetal has two alkoxy groups attached to the same carbon (fully protected carbonyl), while a hemiacetal retains one hydroxyl group. This structural difference can affect classification at the tariff-line level, particularly when additional oxygen functions or derivative substitutions are present. Importers should provide the full IUPAC name and CAS number to their customs broker to confirm the correct heading.
Fragrance and flavor manufacturers use cyclic acetals as aroma chemicals; resin and adhesive producers rely on polyvinyl acetal intermediates; and pharmaceutical synthesizers use derivatized acetals as protecting groups. The specific end-use can also influence whether any EPA Toxic Substances Control Act (TSCA) notification is required prior to import.
