Retrospective GST amendments change exemption and levy rules and bar refunds on paid GST in specified goods.

Amendments give retrospective effect to changes in GST treatment for specified goods: fishmeal exemption is limited with no refunds for paid GST; reduced levy treatment for certain pulley and wheel parts used in agricultural machinery is applied retrospectively, also without refunds; and refunds of accumulated compensation cess credit on tobacco products arising from an inverted duty structure are disallowed retrospectively.
