Ministry of Commerce & Industry DPIIT Completes Migration of Industrial Entrepreneur Memorandum (IEM) Services from G2B Portal to National Single Window System (NSWS)

Posted On: 01 OCT 2025 3:03PM by PIB Delhi Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry, has successfully completed the migration of Industrial Entrepreneur Memorandum (IEM) services from the existing G2B Portal to the National Single Window System (NSWS).

This important reform initiative is aimed at furthering the Government of India’s agenda of Ease of Doing Business and providing a seamless digital experience to entrepreneurs and investors across the country.

All services relating to IEM, including IEM Part-A acknowledgement, IEM Part-B filing and IEM Part-A amendments, will now be available exclusively on NSWS. The NSWS platform provides single-point access to multiple approvals and registrations required by businesses. It also enables auto-population of data from government databases to minimize duplication of entries, allows real-time application tracking for greater transparency, and has an integrated payment gateway for convenient online fee submission.

All new IEM applications must be filed only through the NSWS portal (https://www.nsws.gov.in). Applicants must register and create a new profile on NSWS, as earlier G2B portal login credentials will not be valid.

Applicants are required to complete the profile on NSWS by entering their entity details such as name, contact details, email, CIN, PAN and authorized signatories.

For IEM Part-A filing, applicants must select the “Industrial Entrepreneur Memorandum (IEM)” service under Central Approvals. They are required to fill in project details such as sector, NIC code, item description, production capacity, investment, employment and annual turnover, along with GST details to fetch the manufacturing unit’s location address, and make the prescribed payment online. The system will generate an e-signed acknowledgement which will be available for download from the dashboard.

After commencement of commercial production, applicants must log in to NSWS with the registered user credentials and submit Part-B with relevant details. They are required to select the IEM Part-B filing option and provide the actual production commencement date, actual production capacity and other details.

Any amendments to IEM Part-A can also be filed through NSWS along with the applicable fees. Applicants must select “IEM Part-A Amendment Application” under Central Approvals and pay the amendment fee.

Existing applicants registered on the G2B Portal are required to register themselves afresh on NSWS for IEM acknowledgments. All future filings and amendments must be made through NSWS.

For technical support, applicants may contact the NSWS Helpdesk at nsws@investindia.org.in or toll-free number 1800 102 5841. For any further guidance, they may contact the DPIIT helpdesk at email id: iem-

section-dpiit[at]gov[dot]in or call 011 23061177.

The migration of IEM services to NSWS represents a major milestone in digital governance and investor facilitation, bringing all IEM-related services onto a single-window platform. This step will further enhance the ease of doing business in India and strengthen the country’s position as an attractive global investment destination.
