Antidumping duty on polystyrene: dollar-denominated rates converted to local currency using notified exchange rate at bill of entry. Anti-dumping duties are imposed on imports of HIPS and GPPS from Hong Kong, Singapore and Thailand at specified US dollar rates per metric tonne; imports from the People's Republic of China were treated as de minimis. Duties are to be paid in Indian currency, converted using the Government-notified rate of exchange, with the relevant date for that rate being the date of presentation of the bill of entry.
