This document provides background information and rationale for proposed modifications to an excise duty exemption notification regarding waste and scrap. It notes that the current notification allows full exemption for waste/scrap generated during manufacture of exempted goods, even when intermediate goods used in dutiable final products are exempted. This could allow some unintended benefits. The proposed modification is to provide exemption only when the entire factory's production is exempted, not just intermediate goods. Extracts from the Finance Minister's budget speech support exempting waste/scrap only when the factory itself is fully exempted from excise control.
