Standard International Trade Classification
U.S. imports of Cyclanic, Cyclenic & Cycloterpenic Alcohols and Their Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives (SITC 51231) totaled $15.4M in August 2026, imported from 29 countries.
Importers of Cyclanic, Cyclenic & Cycloterpenic Alcohols and Their Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives paid $1.8M in duties in August 2026, an average duty rate of 13.04% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataCyclanic, cyclenic, and cycloterpenic alcohols — including compounds such as menthol, cyclohexanol, and terpineol — serve as fragrance ingredients, solvent intermediates, and chemical building blocks in flavors, pharmaceuticals, and industrial coatings. The heading also captures their halogenated, sulfonated, nitrated, and nitrosated derivatives, which are more reactive specialty chemicals used in synthesis. Classification within this group turns on whether the ring system is saturated (cyclanic), unsaturated non-aromatic (cyclenic), or terpene-derived, distinctions that require structural documentation from the supplier.

Natural and synthetic menthol are cycloterpenic alcohols and typically fall within this heading. However, the specific HTS tariff line at the 10-digit level may differ based on whether the menthol is natural (derived from mint oils) or synthetic, so importers should confirm the correct line with a licensed customs broker and provide a certificate of origin and analysis.
Nitrated cyclic alcohol derivatives may be subject to additional regulatory scrutiny as potential explosive precursors or hazardous materials, requiring proper DOT hazmat classification, SDS documentation, and potentially EPA TSCA review. Importers should verify whether the specific compound appears on any controlled-substance or precursor chemical list before shipment.
