Anti-dumping duty on Caustic Soda maintained, with country- and exporter-specific rates to address continued dumping and injury. The Central Government, following a sunset review, imposes anti-dumping duty on caustic soda imports from Saudi Arabia, Iran, Japan and the United States, finding continued dumping and material injury to the domestic industry. Duties are specified by country of origin and export, by producer and exporter, and by unit of measurement, with rates stated in foreign currency but payable in Indian currency using the notified exchange rate on bill of entry. The duty is effective for a prescribed statutory period subject to earlier amendment or revocation.
