About heading 2918

Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives

Heading 2918 covers carboxylic acids that carry an additional oxygen function, together with their anhydrides, halides, peroxides, peroxyacids and halogenated, sulfonated, nitrated or nitrosated derivatives. The heading is split first by the type of extra oxygen function: alcohol only (2918.11 through 2918.19), phenol only (2918.21 through 2918.29), aldehyde or ketone only (2918.30), and a residual group (2918.91 through 2918.99). Within each group, lines run from named compounds to baskets for aromatic and other products, with separate lines for pesticides, drugs, and odoriferous or flavoring compounds.
