Anti-dumping duty on hexamine imports from Iran continued to counter dumped imports and protect domestic industry for five years. The Central Government, acting on the designated authority's review findings that imports of Hexa Methylene Tetramine from Iran are dumped and cause substantial injury to the domestic industry, imposes continued anti dumping duty on Hexamine originating in or exported from Iran. The duty is specified per metric tonne in US dollars for calculation, applies irrespective of specification or exporter/producer, is effective for five years from publication unless earlier modified, and must be paid in Indian currency with exchange rate conversion governed by the Government's Customs Act notifications and the bill of entry date.
