# HS code 2918.30: Carboxylic acids with aldehyde or ketone function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives > HS code 2918.30 covers carboxylic acids with aldehyde or ketone function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives. It sits in heading 29.18 (carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives) in chapter 29 (organic chemicals). Other goods of heading 29.18 are classified under 2918.11 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, lactic acid, its salts and esters), 2918.12 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, tartaric acid), 2918.13 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, salts and esters of tartaric acid), 2918.14 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, citric acid) or 11 others.

Its first two digits, 29, are the chapter; the first four, 2918, are heading 29.18; the last two, 30, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 29: Organic chemicals - Heading 29.18: Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives - Subheading 2918.30: Carboxylic acids with aldehyde or ketone function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives ## In other countries No national tariff lines under 2918.30 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2918.30 at six digits and add their own digits after it. - Previous subheading: [2918.29](https://staging.border.bot/hs-codes/291829) Carboxylic acids with phenol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives: Other - Next subheading: [2918.91](https://staging.border.bot/hs-codes/291891) Other: 2,4,5-T (ISO) (2,4,5-trichlorophenoxyacetic acid), its salts and esters ## Frequently asked questions ### What does HS code 2918.30 cover?
