U.S. imports of Cyclic Hydrocarbons, Not Elsewhere Specified or Included (HS 290290) totaled $5.3M in September 2026, imported from 18 countries.
Importers of Cyclic Hydrocarbons, Not Elsewhere Specified or Included paid $689K in duties in September 2026, an average duty rate of 12.92% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: September 2026 dataA structurally diverse residual category, this heading captures cyclic hydrocarbons that do not fall under more specific benzene, toluene, xylene, styrene, or naphthalene headings — including pseudocumene (2902901000), polycyclic aromatics such as acenaphthene, chrysene, and pyrene (2902902000), dodecylbenzene (2902903010), other alkyl and polyalkylbenzenes (2902903050), anthracene (2902904000), and a broad catch-all for remaining cyclic hydrocarbons (2902909000 and 2902909500). India leads US imports under this heading, followed by Spain and Taiwan, reflecting the geographic spread of specialty chemical production. The breadth of compounds covered means classification disputes are common, and the correct 10-digit line depends on the specific compound's chemical identity.

The US schedule under 290290 is organized by named compound: pseudocumene has its own line (2902901000), polycyclics like acenaphthene and pyrene fall under 2902902000, dodecylbenzene under 2902903010, other alkyl/polyalkylbenzenes under 2902903050, anthracene under 2902904000, and remaining compounds under 2902909000 or 2902909500. Classification requires a precise chemical identity — typically confirmed by a Certificate of Analysis — and a licensed customs broker or chemist familiar with CBP classification rulings should be consulted for novel or multi-component products.
Yes. Many cyclic hydrocarbons in this heading are listed on the EPA TSCA Chemical Substance Inventory, requiring TSCA certification at entry. Certain polycyclic aromatic hydrocarbons (PAHs) may also be subject to EPA reporting or import restrictions depending on their specific identity and intended use. Importers should verify TSCA status and any applicable EPA import requirements for each specific compound before shipment.
