U.S. imports of ketone-phenols and ketones with other oxygen functions (HS 291450) totaled $5.5M in May 2026, traded with 21 countries.
Importers of Ketone-Phenols and Ketones with Other Oxygen Functions paid $573K in duties in May 2026 — an effective duty rate of 21% on $2.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ketone-Phenols and Ketones with Other Oxygen Functions imports of $5.5M in May 2026 ran 13% above the year-to-date monthly average of $4.9M.
Last updated: May 2026 dataCompounds combining a ketone group with a phenolic hydroxyl or other oxygen-bearing function — including UV-absorber intermediates and specialty pharmaceutical building blocks — are distributed across four US tariff lines under this heading: a general line (2914500000), a specific sulfonic acid derivative (2914501000), aromatic ketone-phenols (2914503000), and non-aromatic ketone-phenols (2914505000). China and India are the dominant US import sources, and given China's prominence, importers should assess Section 301 tariff applicability at the specific 10-digit line level. The structural complexity of these bifunctional compounds means classification disputes can arise when a compound could plausibly be described under multiple functional-group headings in Chapter 29.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The key criterion is whether the molecule contains both a ketone carbonyl and a phenolic hydroxyl (or other additional oxygen function). If the compound has only a ketone group with no additional oxygen functionality, it belongs in the appropriate acyclic, cyclic, or aromatic ketone heading. A structural formula or CAS-based classification analysis is recommended for borderline cases.
Line 2914501000 covers a named compound — a benzoyl-hydroxy-methoxy-benzenesulfonic acid — that is specifically enumerated due to its commercial use as a UV-absorbing ingredient in sunscreen and polymer stabilizer applications. Its enumeration prevents it from being swept into the broader aromatic ketone-phenol basket, which may carry a different duty rate.
