Its first two digits, 29, are the chapter; the first four, 2917, are heading 29.17; the last two, 19, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 29: Organic chemicals - Heading 29.17: Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives - Within the heading: Acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives - Subheading 2917.19: Other ## In other countries National tariff lines under 2917.19 are live on border.bot for the United States (11 lines, also used by 1 other country). - [United States](https://border.bot/countries/united-states/hs-codes/291719): 11 lines, used by 1 other country - Previous subheading: [2917.14](https://border.bot/hs-codes/291714) Acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives: Maleic anhydride - Next subheading: [2917.20](https://border.bot/hs-codes/291720) Cyclanic, cyclenic or cycloterpenic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives ## Frequently asked questions ### What does HS code 2917.19 cover?
