U.S. exports of Cyclanes, Cyclenes, and Cycloterpenes (Other) (HS 290219) totaled $23.3M in August 2026.
Importers of Cyclanes, Cyclenes, and Cycloterpenes (Other) paid $397K in duties in August 2026, an average duty rate of 10.42% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Cyclanes, Cyclenes, and Cycloterpenes (Other) imports of $3.9M in August 2026 ran 21% below the year-to-date monthly average of $4.9M.
Last updated: August 2026 dataDicyclopentadiene (DCPD) is the most commercially prominent product within this heading, classified at 2902190010, and serves as a key monomer for unsaturated polyester resins, ROMP-based specialty polymers, and hydrocarbon resins used in adhesives and coatings. The remaining lines (2902190000 and 2902190050) cover a broad range of other cycloaliphatic and terpene hydrocarbons not elsewhere specified. Brazil and Spain lead US imports under this heading, followed by Canada, South Korea, and the Netherlands. Correct identification of DCPD versus other cyclanes at the 10-digit level requires clear product naming and CAS number documentation.

Dicyclopentadiene has its own dedicated 10-digit line (2902190010), so importers must confirm the product is specifically DCPD — CAS 77-73-6 — rather than a mixed C5 stream or another cyclopentadiene oligomer. The commercial invoice and CoA should explicitly state 'dicyclopentadiene' and the CAS number; a mixed stream containing DCPD as a component may instead classify under the residual line 2902190050.
Cycloterpenes such as limonene and pinene derivatives are used in fragrance, flavor, and bio-based solvent applications, while cyclopentadiene-derived products feed specialty resin and polymer manufacturing. The diversity of end uses means import volumes can be driven by very different industry cycles — adhesives and coatings demand for DCPD versus consumer goods and cleaning product trends for terpene-based solvents — making demand forecasting more complex than for single-use petrochemicals.
