SIONs for Chemical and Allied Products DGFT Revises SIONs for Chemical & Allied Products: Key Changes Exporters Must Know

DGFT Revises Specific

The Directorate General of Foreign Trade (DGFT) has issued a Public Notice revising certain Standard Input Output Norms (SIONs) under the Chemical and Allied Products category.

The amendment has been issued under the provisions of the Foreign Trade Policy (FTP) 2023 and comes into effect immediately.

What Has Changed?

DGFT has revised the following SIONs under Export Product Group ‘A’ (Chemical and Allied Products):

  • A1090
  • A1794
  • A1827
  • A3105
  • A3106
  • A3107

The revised norms have been notified through Annexure ‘A’ of the Public Notice.

Understanding SIONs

Standard Input Output Norms (SIONs) prescribe the quantity of inputs that can be imported duty-free for manufacturing export products under various export promotion schemes.

These norms play a crucial role in determining eligibility and input consumption limits under schemes such as Advance Authorisation.

Impact on Exporters

Businesses engaged in the export of chemical and allied products should carefully review the revised SIONs to understand how the changes affect:

  • Input-output ratios
  • Duty-free import entitlements
  • Advance Authorisation applications
  • Export costing and planning
  • Compliance documentation

Any exporter operating under the affected SION categories may need to reassess existing authorisations, future applications, and procurement strategies.

Immediate Actions Recommended

Exporters should:

  1. Review the revised SION entries listed in Annexure ‘A’.
  2. Evaluate the impact on current and upcoming export orders.
  3. Verify whether existing Advance Authorisation calculations require modification.
  4. Update internal compliance and documentation processes.
  5. Seek professional guidance where the revised norms impact import entitlements or export profitability.

Effective Date

The amended SIONs are applicable with immediate effect from the date of issuance of the Public Notice.
