Rescission of Central Excise exemptions withdraws specified exemption notifications, effective except for actions taken before rescission. Rescinds three prior Central Excise exemption notifications by exercise of powers under section 5A of the Central Excise Act, 1944, the Government withdraws Notification Nos. 2/2008, 59/2008 and 18/2009 (including recorded amendments), subject to a saving for things done or omitted before the rescission, thereby withdrawing the specified exemption instruments prospectively.
