State tax rate amendment adds specific brick and tile classifications and omits certain lower-rated entries under GST. The notification omits specified serial entries from the 2.5% Schedule I and inserts new serial entries into the 6% Schedule II, expressly listing fly ash bricks or fly ash aggregate with ninety percent or more fly ash content; fly ash blocks; bricks of fossil meals or similar siliceous earths; building bricks; and earthen or roofing tiles as distinct taxable items under the revised State tax rate schedule.
