U.S. imports of Halogenated Derivatives of Cycloalkane, Cycloalkene, and Cycloterpene Hydrocarbons (NESOI) (HS 290389) totaled $765K in August 2026, imported from 8 countries.
Importers of Halogenated Derivatives of Cycloalkane, Cycloalkene, and Cycloterpene Hydrocarbons (NESOI) paid $102K in duties in August 2026, an average duty rate of 13.35% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Halogenated Derivatives of Cycloalkane, Cycloalkene, and Cycloterpene Hydrocarbons (NESOI) imports of $765K in August 2026 ran 17% below the year-to-date monthly average of $927K.
Last updated: August 2026 dataFlame retardants dominate the commercial profile of this heading: dibromoethyldibromocyclohexane (2903890500) and hexabromocyclododecane (HBCD, lines 2903894100 and 2903897010) are widely used in expanded polystyrene insulation and textile back-coatings, though HBCD faces growing regulatory scrutiny under the Stockholm Convention on persistent organic pollutants. The heading also covers chlorinated cycloalkane derivatives (2903893100) used as industrial intermediates. Japan and the United Kingdom are the leading US suppliers, with China, France, and India also contributing — a supply base that spans both specialty chemical producers and large-volume manufacturers.

16 import shipments a month
HBCD is listed under the Stockholm Convention as a persistent organic pollutant, and the US EPA has taken regulatory action under TSCA to restrict its manufacture, processing, and use. Importers of HBCD or articles containing it should verify current TSCA compliance requirements before shipment, as restrictions have tightened and exemptions are limited.
The US schedule carries separate 10-digit lines for hexabromocyclododecane at 2903894100 and 2903897010, as well as a broader NESOI line at 2903897090 for other halogenated cycloalkane derivatives not derived from benzene. The distinction between the HBCD-specific lines and the NESOI line can affect duty treatment, so importers should confirm the precise compound identity and applicable line with a licensed customs broker.
