Exemption scope expanded to include additional paragraph coverage under the central excise notification for finished products, rejects, waste/scrap. The notification amends Notification No. 8/97-Central Excise by substituting the words 'paragraph 6.8' with 'paragraph 6.8 or paragraph 6.20', thereby extending the notification's exemption coverage to include items falling within paragraph 6.20 alongside those in paragraph 6.8 for purposes of exemption of finished products, rejects, waste or scrap under the Central Excise framework.
