Customs notification amendment extends the operative commencement date, deferring the prior commencement to a later date. The Central Government, under powers conferred by the Customs Act, 1962 and the Customs Tariff Act, 1975, amends Notification No. 113/2003-CUSTOMS by substituting in paragraph 2 the previously stated commencement date with a later commencement date, thereby deferring the operative effect of that notification as published in the Gazette.
