  "summary": "HS heading 29.17 covers polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives. It is in chapter 29 (organic chemicals). It is split into 13 subheadings: 2917.11 (acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives, oxalic acid, its salts and esters), 2917.12 (acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives, adipic acid, its salts and esters), 2917.13 (acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives, azelaic acid, sebacic acid, their salts and esters), 2917.14 (acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives, maleic anhydride), 2917.19 (acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives, other), 2917.20 (cyclanic, cyclenic or cycloterpenic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives) and 7 others. National tariff lines under heading 29.17 are live on border.bot for the United States (36 lines, also used by 1 other country).",
