U.S. imports of unsaturated chlorinated derivatives of acyclic hydrocarbons (other) (HS 290329) totaled $7.0M in April 2026, traded with 12 countries.
Importers of Unsaturated Chlorinated Derivatives of Acyclic Hydrocarbons (Other) paid $755K in duties in April 2026 โ an effective duty rate of 11% on $6.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataThe Czech Republic leads US imports of other unsaturated chlorinated acyclic hydrocarbon derivatives, ahead of China and Germany, under the single 10-digit line 2903290000. Compounds in this residual category serve as chemical intermediates in the synthesis of agrochemicals, pharmaceuticals, and specialty polymers, where the carbon-carbon double bond is a key reactive site. Because this is a catch-all NESOI line, precise chemical identity documentation โ including CAS numbers and structural formulas โ is essential to confirm correct classification and distinguish these compounds from named headings such as vinyl chloride (290321) or trichloroethylene (290322).
AI-written summary of the official U.S. Census Bureau trade figures on this page โ verify before relying on it.
Classification follows the GRI specificity rule: named compounds such as vinyl chloride (290321) and trichloroethylene (290322) take precedence over the NESOI residual heading 290329. If the imported compound is not expressly named in a more specific heading, and it is an unsaturated chlorinated acyclic hydrocarbon, it falls under 290329. A licensed customs broker or CBP binding ruling can confirm classification for novel or ambiguous structures.
Primary end-use sectors include agrochemical synthesis (as halogenated building blocks), specialty polymer production, and pharmaceutical intermediate manufacturing. The reactive double bond makes these compounds valuable for further chemical transformation rather than direct end-use application.
