SITCSection 5
U.S. imports of carboxylic acids with aldehyde or ketone function & derivatives (SITC 51395) totaled $7.0M in April 2026, traded with 17 countries.
Importers of Carboxylic Acids with Aldehyde or Ketone Function & Derivatives paid $505K in duties in April 2026 — an effective duty rate of 7.3% on $6.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Carboxylic Acids with Aldehyde or Ketone Function & Derivatives imports of $7.0M in April 2026 ran 25% above the year-to-date monthly average of $5.6M.
Last updated: April 2026 dataKeto-acids and aldehyde-acids — organic acids whose only additional oxygen function is a carbonyl group — occupy this heading, covering compounds such as pyruvic acid, levulinic acid, and acetoacetic acid derivatives. Levulinic acid has attracted growing interest as a bio-based platform chemical derived from lignocellulosic biomass, positioning it as a renewable feedstock for solvents, fuel additives, and polymer precursors. Trade professionals should be aware that several acetoacetate esters used as pharmaceutical or flavor intermediates may trigger FDA documentation requirements depending on their intended application.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Levulinic acid is a keto-acid classifiable under this heading and is gaining commercial traction as a bio-based platform chemical for producing solvents (e.g., gamma-valerolactone), plasticizers, and fuel additives. Its renewable origin does not change its SITC classification, but buyers should confirm the production route and purity specification, as bio-derived and petrochemical-derived grades may differ in impurity profiles relevant to downstream processing.
Yes, acetoacetate esters — where the ketone carbonyl is the only additional oxygen function beyond the ester linkage — are generally classifiable here. These compounds are widely used as pharmaceutical intermediates and flavor chemicals. Importers should verify the specific compound's CAS number against the heading's structural criteria and consult a customs broker if the compound contains additional functional groups that might place it under a different heading.
