U.S. imports of ketone-alcohols and ketone-aldehydes (HS 291440) totaled $7.0M in June 2026, traded with 18 countries.
Importers of Ketone-Alcohols and Ketone-Aldehydes paid $705K in duties in June 2026 — an effective duty rate of 10% on $6.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ketone-Alcohols and Ketone-Aldehydes imports of $7.0M in June 2026 ran 60% above the year-to-date monthly average of $4.4M.
Bifunctional compounds carrying both a ketone group and either a hydroxyl or aldehyde group are enumerated across five US tariff lines, including diacetone alcohol (2914401000), ninhydrin (2914402000), 1,3-dihydroxyacetone (2914406000), aromatic ketone-alcohols and ketone-aldehydes (2914404000), and a residual non-aromatic line (2914409000). Germany leads US imports of this heading, with China and Taiwan also significant sources. Ninhydrin's use in forensic and analytical chemistry and 1,3-dihydroxyacetone's role as the active ingredient in sunless tanning products illustrate the commercial breadth of this heading, and importers should confirm the correct aromatic versus non-aromatic line assignment.

DHA is classified under 2914406000 as a non-aromatic ketone-alcohol. When imported as a cosmetic active ingredient (e.g., for self-tanning products), it falls under FDA's cosmetic ingredient oversight framework. Importers should ensure product labeling and safety documentation comply with FDA cosmetic regulations, though DHA itself does not require pre-market approval as a drug.
The aromatic line covers ketone-alcohols and ketone-aldehydes where the ketone function is attached to an aromatic ring system. Compounds without an aromatic ring — such as diacetone alcohol or DHA — fall into the non-aromatic lines. Correct assignment requires identifying the ring structure (or absence thereof) in the molecule.
