Explanation – Standard Input Output Norms (SION) are specifically used in the context of regulating and facilitating international trade in India. They are established by the Directorate General of Foreign Trade (DGFT) to specify the quantity of inputs required to produce a unit of output for exporting purposes. SION plays a crucial role in determining exporters’ eligibility for various benefits and incentives provided by the Indian government, and in ensuring uniformity and transparency in export-import processes.
