- Detailed changes for each SION are provided in Annexure ‘A’ of the public notice.
Legal Authority
- The revisions are made under the powers granted by paragraphs 1.03 and 2.04 of the Foreign Trade Policy-2023, as amended.
Immediate Effect
- The amended SIONs are effective immediately from the date of publication (May 29, 2026).
