SITCSection 5
U.S. imports of carboxylic acids with alcohol function & derivatives, nes (SITC 51392) totaled $12.0M in April 2026, traded with 22 countries.
Importers of Carboxylic Acids with Alcohol Function & Derivatives, NES paid $1.0M in duties in April 2026 — an effective duty rate of 16% on $6.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Carboxylic Acids with Alcohol Function & Derivatives, NES imports of $12.0M in April 2026 ran 32% above the year-to-date monthly average of $9.1M.
Last updated: April 2026 dataHydroxy-carboxylic acids — compounds carrying both carboxyl and hydroxyl groups but classified outside the named lactic/tartaric/citric heading — fall here along with their anhydrides, halides, and other derivatives. Mandelic acid, malic acid (when not separately classified), and glycolic acid are representative members, each serving distinct roles in pharmaceutical synthesis, personal-care formulations, and industrial descaling. The NES qualifier means classification discipline is essential: importers should confirm that the specific compound is not captured by a more specific SITC heading before declaring under this code.

Glycolic acid, a hydroxy-carboxylic acid, is generally classifiable under this heading when not covered by a more specific provision. End use does not change the chemical classification, but it does affect downstream regulatory requirements: glycolic acid in cosmetic formulations is subject to FDA oversight, while industrial-grade material used as a descaler may face different documentation expectations. Importers should confirm the applicable grade and intended use with their customs broker.
The lactic/tartaric/citric heading is reserved for those three named acids and their salts and esters specifically. Any other carboxylic acid whose only additional oxygen function is a hydroxyl group — such as mandelic acid or glyceric acid — falls under this NES heading. When a product could plausibly fit either, the CAS number and structural formula should be reviewed against the explicit named-acid list before classification is finalized.
