Its first two digits, 29, are the chapter; the first four, 2916, are heading 29.16; the last two, 32, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 29: Organic chemicals - Heading 29.16: Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives - Within the heading: Aromatic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives - Subheading 2916.32: Benzoyl peroxide and benzoyl chloride ## In other countries National tariff lines under 2916.32 are live on border.bot for the United States (2 lines, also used by 1 other country). - [United States](https://border.bot/countries/united-states/hs-codes/291632): 2 lines, used by 1 other country - Previous subheading: [2916.31](https://border.bot/hs-codes/291631) Aromatic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives: Benzoic acid, its salts and esters - Next subheading: [2916.34](https://border.bot/hs-codes/291634) Aromatic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids and their derivatives: Phenylacetic acid and its salts ## Frequently asked questions ### What does HS code 2916.32 cover?
