Social Welfare Surcharge exemption revised: specified tariff items added and certain textile items removed from exemption. The notification amends Notification No. 11/2018-Customs by inserting numerous tariff headings into the exemption table, omitting or substituting specified textile tariff entries, and deleting serial numbers three and four, thereby revising the set of goods exempt from the Social Welfare Surcharge and reconfiguring exemption coverage through tariff classification changes; the amendment carries an express commencement date.
