GST classification change: omission of concessional entry for certain railway coaches alters taxable treatment for rail supplies. GST treatment for certain non self propelled railway and tramway coaches has changed following omission of the specific concessional tariff entry; the removal ends the lower-rate classification for those coaches and requires goods to be classified under the appropriate chapter headings, with supplies to Indian Railways classified under chapters other than Chapter 86 treated according to that chapter as clarified by the relevant circular.
