U.S. exports of Cyclanic, Cyclenic & Cycloterpenic Ethers and Their Halogenated, Sulfonated, Nitrated & Nitrosated Derivatives (HS 290920) totaled $868K in August 2026.
Importers of Cyclanic, Cyclenic & Cycloterpenic Ethers and Their Halogenated, Sulfonated, Nitrated & Nitrosated Derivatives paid $101K in duties in August 2026, an average duty rate of 30.76% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataCovered entirely by a single 10-digit line (2909200000), cyclanic, cyclenic, and cycloterpenic ethers occupy a specialized niche in fragrance chemistry, pharmaceutical synthesis, and specialty polymer production, where the ring structure imparts distinct reactivity and stability compared to acyclic analogs. China is the primary US supplier, followed by Germany and Spain. Importers sourcing from China should assess Section 301 exposure, as many cyclic organic intermediates fall within the scope of those measures.

Cyclanic, cyclenic, and cycloterpenic ethers contain saturated or partially unsaturated non-aromatic rings, whereas aromatic ethers contain a benzene or other aromatic ring system. The presence or absence of aromaticity in the ring is the key structural criterion; compounds with aromatic rings are classified under heading 2909.30 rather than 2909.20.
At the 10-digit US level, all cyclanic, cyclenic, and cycloterpenic ethers and their halogenated, sulfonated, nitrated, or nitrosated derivatives are consolidated under 2909200000. There are no further US-level subdivisions, so the classification decision rests entirely on confirming the compound's ring type and ether functionality.
