HS Chapter 12: Oil seeds and oleaginous fruits, miscellaneous grains
The First Schedule to the Customs Tariff Act, 1975 heads chapter 12 as “Oil seeds and oleaginous fruits, miscellaneous grains, seeds and fruit; industrial or medicinal plants; straw and fodder”. Every tariff item in chapter 12 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.
