Customs exemption amendment expands tariff coverage to include chapter 86, broadening repair-and-return and export-use relief. Amendment replaces the words 'chapter 88 or 89' with 'chapter 86 or chapter 88 or chapter 89' in the proviso to clause (ii) of serial number 1 in the TABLE of Notification No. 153/94 Customs, thereby expanding the scope of the exemption for goods of foreign origin used for repairs and return or for use on articles for export; the change is made under the stated statutory powers and takes effect on 2 February 2025.
