Customs tariff amendment: specified exemption rate substituted with a lower rate under delegated rulemaking powers. Amendment substitutes the figures '5.75%' with '5%' in Notification No. 259/92-Cus by exercise of powers under the Customs Act, 1962, as necessary in the public interest; the change is confined to the numerical alteration of the tariff/exemption rate and does not modify other operative conditions of the parent notification.
