Anti-dumping duty on caustic soda sustained with country- and exporter-specific rates and targeted producer exemptions. Imposition of anti-dumping duty on Caustic Soda originating in or exported from the People's Republic of China and Korea Republic follows a review finding continued dumping by non-cooperative producers and significant dumping and injury margins. Duties are differentiated by country of origin, country of export and by named producers/exporters, with certain producer-exporter combinations exempted from duty and other imports subject to specified per-unit duties in US dollars per dry metric tonne. The duty is effective for five years from publication, payable in Indian currency, with exchange rate for calculation determined by separate notifications and the bill of entry date as the relevant date.
