GST applicability on rubberised textile fabrics excluded from certain headings remains in effect until the specified deadline. A temporary tax provision applies GST at 12% to rubberised textile fabrics classified under chapter 59, covering goods described as rubberised textile fabrics distinct from items classified under a separate heading, and operative under the applicable tariff schedule until the stated expiry date; the measure fixes tax incidence on this product category by exclusion of items allocated to other headings.
