HS Chapter 24: Tobacco and manufactured tobacco substitutes; products
The First Schedule to the Customs Tariff Act, 1975 heads chapter 24 as “Tobacco and manufactured tobacco substitutes; products, whether or not containing nicotine, intended for inhalation without combustion; other nicotine containing products intended for the intake of nicotine into the human body”. Every tariff item in chapter 24 that this dataset carries a duty and a tax rate for, listed by heading so a code can be found by reading rather than by guessing. The rates sit on the code itself: open any item for the standard rate of basic customs duty from the First Schedule to the Customs Tariff Act, 1975, the integrated tax beside it, the surcharge and cess on top with the base each is charged on, and the part a duty-credit scrip can pay.
