Integrated tax exemption extended to customs tariff on specified goods, applying from the notified commencement date. The notification amends the opening paragraph of the exemption notification to substitute wording so that goods specified in the First Schedule are exempted and the exemption expressly extends to the integrated tax leviable under the Customs Tariff Act provision referenced in the amendment; the Central Government issues the change under its statutory power and makes it effective from the notified commencement date.
