Class 3 signing
Individuals, directors, CAs
Tax and company filings, EPFO, tenders and GeM, trademark and reissue.

To bid on government tenders in Rajasthan you register on the Rajasthan eProcurement portal. This post walks the full process in plain language: which tenders go online, which certificate you need, and what to watch for when you register and submit a bid.
Rule 5 of the Rajasthan Transparency in Public Procurement Rules 2013 mandates e-procurement for values notified by the state. The notification effective 1 September 2016 made e-procurement compulsory for goods and services of ₹10 lakh or more and works of ₹5 lakh or more. Thresholds may have been amended after 2016, so check the latest notification before assuming a tender is online.
The eProc DSC information page states that a DSC of Class 3 category issued by a licensed Certifying Authority needs to be obtained for e-filing on the eTendering portal. For Rajasthan eProc, a Class 3 signing DSC is enough; an encryption certificate is not needed. For e-tendering on other states’ portals or India-wide portals, we recommend the combo (signing plus encryption). Our listed CAs include VSign, Capricorn, eMudhra, Sify, nCODE and PantaSign. If your tender names specific CAs, confirm acceptance with the portal helpdesk before you apply.
The portal describes a two step enrolment process. Here it is in plain steps.
A DSC mapped to one account cannot be remapped to another; it can only be inactivated. This mapping rule is important if you change organisations or roles.
The portal’s instructions for bidders cover the submission steps and the mistakes that get bids rejected. The BOQ template must not be modified or replaced by the bidder; it is uploaded after filling in the relevant columns only. Bid documents should be in PDF, XLS, RAR or DWF formats. Check for corrigenda before you submit. The portal also publishes a Guidelines for Hassle Free Bid Submission PDF, which is worth reading before you enrol.
Government e-Marketplace (GeM) is a central portal. Its FAQ states that only Class 3 certificates can be used for digital signing on GeM. The Central Public Procurement Portal (CPPP) has its own DSC information page and bidders manual kit. Check the CPPP guidance for its class and combo requirements.
