  "summary": "HS code 2918.23 covers carboxylic acids with phenol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, other esters of salicylic acid and their salts. 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. National tariff lines under 2918.23 are live on border.bot for the United States (4 lines, also used by 1 other country).",
