U.S. imports of cyclic aldehydes without other oxygen functions (nesoi) (HS 291229) totaled $9.6M in April 2026, traded with 12 countries.
Importers of Cyclic Aldehydes Without Other Oxygen Functions (NESOI) paid $1.2M in duties in April 2026 — an effective duty rate of 16% on $7.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Cyclic Aldehydes Without Other Oxygen Functions (NESOI) imports of $9.6M in April 2026 ran 15% above the year-to-date monthly average of $8.3M.
Last updated: April 2026 dataCovering aromatic and non-aromatic cyclic aldehydes that lack additional oxygen-bearing functional groups — including phenylacetaldehyde (2912291000), tolualdehyde and 3,4-dimethylbenzaldehyde (2912293000), and several odor/flavor compound lines — this heading is a workhorse for the fragrance and flavor industry. Japan and Mexico are the leading US suppliers, with China and India also prominent; the heading's six 10-digit lines split primarily between designated named compounds and basket categories for odor/flavor use versus general industrial use. Importers should pay close attention to which specific line applies, as the odor/flavor compound lines (2912290020 and 2912296010) carry distinct classification criteria from the general NESOI lines.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Lines 2912290020 and 2912296010 are reserved for cyclic aldehydes used specifically as odoriferous or flavoring compounds, while 2912290090 and 2912296090 cover all other cyclic aldehydes not elsewhere specified. Classification hinges on the commercial end-use and chemical identity; importers should document the intended application and consult a licensed customs broker to ensure the correct line is declared.
Phenylacetaldehyde (2912291000) is monitored as a List I chemical precursor under DEA regulations because it can be used in the illicit synthesis of certain controlled substances. Importers may need to comply with DEA import notification or registration requirements in addition to standard CBP entry procedures.
