Industrial Entrepreneurs Memorandum (IEM): Who Must File, Part A and Part B, and How to Do It

An Industrial Entrepreneurs Memorandum (IEM) is a self-declaration filed with the Department for Promotion of Industry and Internal Trade (DPIIT) by industrial undertakings that are exempt from industrial licensing under the Industries (Development and Regulation) Act, 1951. It is filed in two parts: Part A to declare the intent to set up or substantially expand a unit, with a fee of ₹1,000, and Part B, free of cost, to report the start of commercial production. IEM is now filed on the National Single Window System (NSWS), and it does not replace other statutory approvals

Key Takeaways

  • IEM applies to industrial undertakings that are exempt from industrial licensing and are generally larger scale units, while small units register on Udyam instead.
  • Part A declares the intention to establish the unit, or to carry out substantial expansion or manufacture a new article, and Part B reports commencement of commercial production.
  • The IEM is a self-certification. DPIIT does not appraise the project before issuing the acknowledgement, and the filing does not exempt the entrepreneur from other statutory approvals.
  • The Part A fee is ₹1,000 and there is no fee for Part B.
  • IEM filing now happens on the National Single Window System, and credentials from the older G2B portal do not carry over, so existing holders may need a fresh NSWS account.
  • Common errors include treating IEM as a one-time filing, never filing Part B after production begins, and showing an investment figure in Part B that does not match Part A.

What an IEM is

  • Under the Industries (Development and Regulation) Act, 1951, only a short list of industries needs an industrial licence. Every other industrial undertaking is exempt from licensing, but the Government still wants to know about new large units and major expansions. The Industrial Entrepreneurs Memorandum is how those exempt units inform DPIIT.
  • For a de-licensed sector the IEM replaces the industrial licence for practical purposes, but it is an information filing, not a permission. The entrepreneur still needs environmental, factory, state and local approvals separately.

Who needs to file an IEM

  • A new industrial undertaking that is exempt from industrial licensing and falls outside the micro, small and medium category
  • An existing exempt unit planning substantial expansion
  • A unit proposing to manufacture a new article that is not covered by its existing registration
  • An MSME that has graduated into a large scale industry
  • Not required for micro, small and medium enterprises, which register on the Udyam portal, and not the right form for industries that actually need an industrial licence

Documents usually needed

  • Certificate of incorporation, MOA and AOA, or partnership deed of the entity
  • PAN and GST details of the entity
  • Details of the proposed or existing location and the investment plan
  • List of products or articles to be manufactured, with relevant industry codes
  • Authorisation for the person filing, such as a board resolution or authority letter
  • For Part B, the Part A acknowledgement and proof of the commencement date

How to file an IEM on NSWS

  • Create or log in to your account on the National Single Window System at nsws.gov.in.
  • Open Central Approvals and select Industrial Entrepreneur Memorandum.
  • Choose IEM Part A, fill in the online form and upload the documents.
  • Pay the ₹1,000 fee online and submit to receive the Part A acknowledgement.
  • After production starts, select the earlier Part A filing, choose File Part B and submit the commencement details at no cost.
  • File an amendment on the same portal if details such as investment or product line change, keeping the changes consistent with the original intent.

Why IEM matters in practice

  • The IEM acknowledgement is commonly asked for when applying for state industrial incentives, certain tenders, bank project finance and approvals from other departments. Skipping Part B can create problems later, because the record will show that the unit never reported commencement. Keep copies of both acknowledgements with your project file.
