Standard Input-Output Norms (SION)

The Direct General of Foreign Trade (DGFT) has published the Standard Input Output Norms (SION) to specify the required amount of inputs needed to produce a unit of outputs for exporting. SION is applicable for numerous products, including electronics, engineering, chemical, handicraft, plastic, leather, and many more; it is also suitable for various food products such as fish and other marine products. Advance licenses are issued based on the inputs and export items given under SION, and the applicant's exporter needs to ensure that the goods sought for import and import are used in the export product. The manufacturer, exporter, and merchant-exporter can modify these norms by applying DGFT. Get Importer Exporter Code (IEC) through IndiaFilings

SION for Advance Authorizations

As explained above, based on the Standard Input Output Norms (SION), the Government issues advance authorizations for inputs and export items. The Advance Authorization allows duty-free import of information, which is physically incorporated into the export product. As per SION, the duty-free import of fabric is permitted under the Special Advance Authorization Scheme for the export of Articles of Apparel and Clothing Accessories. A duty-Free Replenishment Certificate (DFRC) also shall be issued for the import of inputs as per SION as indicated in the shipping bills.

Condition for Exports

The applicant's exporter needs to ensure that the goods sought for import and importation are used in the export product. According to SION, the customs authority will check whether the items allowed in the import license are co-related with the description of the export product in the Shipping Bill. For better understanding, kindly go through this example: If the input allowed in the SION is 'relevant fabrics,' only the specific types of Polyester or nylon used in the products will be approved for export. Similarly, if the input-output norms provide for the import of BOPP film against the trading of self-adhesive tape, only BOPP film required for the manufacture of Self Adhesive Tape will be allowed for shipping.
