U.S. imports of acyclic ketones without other oxygen function (nesoi) (HS 291419) totaled $2.7M in June 2026, traded with 16 countries.
Importers of Acyclic Ketones Without Other Oxygen Function (NESOI) paid $276K in duties in June 2026 — an effective duty rate of 11% on $2.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Residual acyclic ketones not elsewhere specified — covering compounds such as diethyl ketone, methyl propyl ketone, and other non-enumerated aliphatic ketones — enter under a single basket line, 2914190000. Germany and China are the leading US suppliers of this chemically diverse category, which feeds into pharmaceutical synthesis, flavor and fragrance manufacturing, and specialty chemical production. Because the heading is a catch-all, correct classification requires confirming that the specific compound is not enumerated under a more specific HS6 subheading within Chapter 29. Importers dealing with novel or multi-functional acyclic ketones should obtain a binding ruling to avoid reclassification risk.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A compound is classified here only if it is acyclic, carries no additional oxygen-bearing functional groups (such as hydroxyl or aldehyde), and is not specifically named in headings 291411 through 291413. If a compound meets any of those more specific criteria, it must be classified there instead.
CBP may request a certificate of analysis, MSDS, or structural formula to confirm the compound is correctly classified as an acyclic ketone without other oxygen function. For novel or proprietary compounds, a binding ruling request provides the most reliable classification certainty.
