GST schedule amendment broadens chapter coverage and removes restrictive wording in specified tariff entries, altering product descriptions. Corrigendum effects textual corrections to GST schedule entries: Schedule I entry at serial 180 is amended to read as the heading or any chapter, broadening chapter coverage; Schedule III entry at serial 42 omits the words 'other than those'; and Schedule III entry at serial 411 omits the words referencing certain eyewear and qualifying descriptors, thereby altering the descriptive text used for classification under the GST schedules.
