Anti dumping duty rescission removes a prior levy on potassium carbonate under Customs Tariff Act authority. The Central Government, invoking sub-section (2) of section 9A of the Customs Tariff Act, 1975 read with rules 13 and 20 of the 1995 Anti-dumping Rules, hereby rescinds Notification No.66/2007-Customs dated 9 May 2007 and thus withdraws the previously imposed anti-dumping duty on potassium carbonate as published in the Gazette of India.
