HS Chapter 86: Railway or tramway locomotives, rolling-stock and parts thereof
The First Schedule to the Customs Tariff Act, 1975 heads chapter 86 as “Railway or tramway locomotives, rolling-stock and parts thereof; railway or tramway track fixtures and fittings and parts thereof; mechanical (including electro-mechanical) traffic signalling equipment of all kinds”. Every tariff item in chapter 86 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.
