How much customs duty I have to pay if I purchase 40 inches led tv from bangkok and bring it chennai india?

The customs duty on importing a 40-inch LED TV into India generally consists of Basic Customs Duty (BCD), Integrated Goods and Services Tax (IGST), and possibly other applicable cess. As of my last update, the BCD for televisions is around 20%, and the IGST is typically 18%. Therefore, you would need to calculate the duty based on the TV's assessable value, which includes the cost, insurance, and freight (CIF). It's advisable to check the latest customs regulations and rates as they may vary.
