Migration from G2B Portal to National Single Window System (NSWS) Portal
Note: The Industrial Entrepreneur Memorandum (IEM) process, earlier facilitated through the
G2B Portal, has been fully migrated to the National Single Window System (NSWS).
All new applications for IEM Part-A, Part-B, and Amendments must now be submitted
exclusively through the National Single Window System (NSWS) Portal:
Link.
Note: Existing applicants registered on the G2B Portal are required to register themselves afresh
on NSWS for IEM Acknowledgments:
https://www.nsws.gov.in
Note: "All applicants whose IEM applications have already been submitted and are currently under process on the G2B Portal are hereby requested to urgently furnish their clarifications/responses to the queries raised by the IEM Section on or before 20th October, 2025,
as the IEM services on the G2B Portal shall be discontinued thereafter."
