SION-based usage norms revised, allowing self-declared/ad hoc inputs and clarifying deemed import treatment for EOUs and STP units. The notification permits non-capital goods to be treated as used for export production or home-consumption clearance if proven to the officer within a prescribed period or extended for sufficient cause; where no SION exists, waste, scrap and remnants up to two percent are allowed, and units may use self-declared norms pending ad hoc fixation by the Development Commissioner and must align with Board of Approval norms within the prescribed adjustment period. It also clarifies that certain supplies from EOUs, STP and EHTP units and specified deemed exports are to be treated as imported goods.
