SION norms are pertinent for various products, including engineering, chemical, electronics, handicraft, plastic, leather, and others.

All You Need To Know About Standard Input- Output Norms (SION)

The Direct General of Foreign Trade introduced SION norms to limit the number of inputs to produce outputs for exporting. SION norms are pertinent for various products, including engineering, chemical, electronics, handicraft, plastic, leather, and others. These norms are applicable for food products such as fish, and other marine products. Under SION norms, advance licenses are issued, and the applicant needs to assure that the goods sought for import get utilized in the export product. However, SION norms can be modified by manufacturer exporter and merchant-exporter by applying DGFT.

SION Norms For Advance Authorizations

The government issues advance authorizations for items for import and export based on SION norms. Advance authorization enables duty-free import of inputs that are subsumed in the products for exports. According to SION norms, the Special Advance Authorization Scheme allows the duty-free import of fabric. A Duty-Free Replenishment Certificate (DFRC) is also essential for the import of inputs according to the SION norms.

Condition for Exports

As per the SION norms, customs authorities are responsible for checking whether the items mentioned in the import license are included with the description of the export products in the shipping bill or not.

To simplify it, consider this example: if the SION norms allow the import of BOPP film against the trade of self-adhesive tape, only BOPP film essential for self-adhesive tape manufacturing will be allowed for shipping.

Technical Details for Modifying SION Norms

For modification of SION norms, the exporter is expected to produce some technical details:

Chemical Products, Drugs, and Pharmaceuticals

  • Step-by-step manufacturing

  • All chemical reactions in the manufacturing procedure along with molecular and structural formula, molecular weight, and percentage yields on a molar basis of every stage.

  • Material balance of complete manufacturing process
