When you need it
An enterprise registered on the Udyam portal wants to record and declare its Udyam Registration Number and MSME classification in one document — to hand to a customer or buyer who needs it on file, to a bank for a loan application, or simply as its own record of the basis on which it is classified.
Udyam Registration itself is done online, based on self-declaration, using the enterprise's PAN and GST-linked data, under the notification of the Ministry of Micro, Small and Medium Enterprises dated 26 June 2020 issued under ss.7 and 8 of the Micro, Small and Medium Enterprises Development Act, 2006, with effect from 1 July 2020. This document does not replace that registration — it is what an already-registered enterprise signs to declare its Udyam particulars to a third party, most often because s.9 of that Act requires certain buyers to disclose in their annual accounts the amount due to micro and small enterprise suppliers, and because s.15 fixes the time within which such a buyer must pay — never later than forty-five days from the day of acceptance where there is a written agreement, and interest under s.16, at three times the bank rate notified by the Reserve Bank of India, compounded monthly, becomes payable on a delayed payment.
For any enterprise registered, or applying to register, on the Udyam portal, wherever it is located, including Punjab and Chandigarh. Not the registration application itself, which is made only at udyamregistration.gov.in.
