Customs notification amendment postpones the operative commencement date for a specified tariff exemption. Amendment to Notification No. 113/2003-CUSTOMS substitutes the figures, letters and words in paragraph 2 specifying the commencement date with a later commencement date; the Central Government acts under powers conferred by the Customs Act and the Customs Tariff Act and records the change as a further amendment to the principal notification published as G.S.R. 572(E).
