What EMD is for
EMD, also called bid security, is money a bidder puts down to show the bid is serious. The buyer holds it while bids are evaluated. If the bidder withdraws or changes the bid during the bid validity period, or wins and then fails to sign the agreement or submit the performance security, the EMD is forfeited.
Central government buyers follow the General Financial Rules (GFR 2017), which put bid security at 2 to 5% of the estimated value of the procurement. State departments and PSUs set their own figure, often a fixed amount. The amount for any tender is stated in its NIT; that figure, not a rule of thumb, is what you pay.
How EMD is paid and returned
On CPPP and the state e-procurement portals EMD is usually paid online (net banking or NEFT/RTGS to the department's account through the portal) or as a demand draft or bank guarantee whose scanned copy is uploaded and the original delivered before bid opening. GeM bids state whether EMD is required and how it is paid.
Unsuccessful bidders' EMD is refunded after the award, without interest. The successful bidder's EMD is either returned once the performance security is received or adjusted against it, as the tender says.
Who does not pay EMD
Micro and small enterprises registered under Udyam (or with NSIC) are exempt from EMD in central government procurement of goods and services under the Public Procurement Policy for MSEs. Works tenders and many state departments follow their own rules, so check the exemption clause of the tender.
Many tenders now accept a Bid Securing Declaration in place of EMD: a signed undertaking that the bidder accepts suspension from future tenders if it withdraws or fails to perform. GeM bids for startups recognised by DPIIT also commonly waive EMD.
