Code 2918 19 · Heading 2918

Alcohol-group-containing carboxylic acids, their derivatives and related compounds, excluding the specifically listed acids and compounds

This category covers carboxylic acids containing alcohol groups but no other oxygen-containing groups, together with their anhydrides, halides, peroxides, peroxyacids and halogen-, sulfo-, nitro- or nitroso-derivatives. It excludes lactic, tartaric, citric and gluconic acids, cholic acid, deoxycholic acid, 2,2-bis[hydroxymethyl]propionic acid, chlorbenzilate and benzilic acid, as well as the salts and esters covered by the title.
