GST omission for marble and travertine removes the prior scheduled tax entry, changing classification and compliance. The Schedule 4 entry taxing 'Marble and travertine, other than blocks' was omitted by notification no. 43/2017 effective 15-11-2017, altering the schedule classification and GST coverage for those stone products, notwithstanding that Schedule 4 goods were listed as subject to GST at the stated rate up to 21-09-2025.
