Anti-dumping duty on Hexamine imports imposed due to continued dumping and injury, with country-specific duties and five-year duration. Imposition of definitive anti-dumping duty on Hexamine (tariff item 2921 29 10) originating in or exported from Saudi Arabia and Russia is continued and modified after a review found continued dumping and likely injury. The notification prescribes country-, producer- and exporter-specific duty rates per metric tonne in US dollars, requires payment in Indian currency using Government-specified exchange rates with the bill-of-entry date as the relevant date, and keeps the duty effective for five years from Gazette publication unless earlier changed.
