U.S. imports of carboxylic acids with alcohol function, nesoi (HS 291819) totaled $7.4M in July 2026, traded with 20 countries.
Subheading 6 of 17 in heading 2918
Subheading 291819 · $7.4M of $108.6M
Importers of Carboxylic Acids with Alcohol Function, NESOI paid $1.1M in duties in July 2026 — an effective duty rate of 17% on $6.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Mandelic acid, malic acid, and related hydroxy-carboxylic acids not elsewhere specified span a wide range of pharmaceutical, food-acidulant, and specialty-chemical applications, making classification precision critical — the US schedule breaks this heading into nine distinct 10-digit lines including methyl ester (2918191100), mandelic acid (2918191200), phenylglycolic acid and its salts and esters (2918191350), malic acid (2918196000), and several aromatic and non-aromatic residual categories. India leads US import supply for this heading, followed by China and France, reflecting the concentration of fine-chemical and pharmaceutical-intermediate manufacturing in South Asia and Europe. Importers should verify whether a specific compound falls under the pharmaceutical-intermediate carve-outs referenced in Additional US Note 3 to Section VI, as that distinction routes goods to different 10-digit lines with potentially different duty treatment.

The key distinctions are aromatic versus non-aromatic structure and whether the compound is specifically enumerated (e.g., mandelic acid, phenylglycolic acid, malic acid) or falls into a residual basket. Aromatic compounds without other oxygen functions go to 2918192000, while non-aromatic compounds with additional oxygen functions not otherwise specified land in 2918199000. When the compound is a named acid, its specific line takes precedence over any basket provision.
Yes. Several lines within this heading — including 2918193100 — explicitly exclude or include products described in Additional US Note 3 to Section VI, which covers certain chemical compounds subject to special duty treatment. Importers should review the note carefully and confirm with a licensed customs broker whether their specific compound qualifies, as misclassification between the Note 3 and non-Note 3 lines can affect the applicable duty rate.
