OEM authorisation certificate in a GeM bid, explained
OEM authorisation certificate (OEM Authorization Certificate). A letter from the original equipment manufacturer authorising a named bidder to quote its product in a specific bid. A reseller bidding someone else's product needs one when the bid document asks for it.

Where it appears
In the documents required from the seller, in the GeM bid document. It is one line, and it decides whether the tender is open to you before anything about price or scope does.
The three cases
You manufacture the product you are bidding: you are the OEM and need nobody's authorisation.
You are a trader or reseller bidding somebody else's product: you need that manufacturer's authorisation, and getting it takes as long as it takes them to reply. Start on day one of the bid window, not day nine.
You manufacture, but you are bidding a competitor's product: you almost certainly cannot get one. A competitor has no reason to authorise you. Knowing this on the first morning saves the whole window.
Why it is worth reading early
Most eligibility terms can be checked against your own records in a minute: turnover, years of experience, registrations. The OEM authorisation is the one that depends on a third party, so it is the one with a lead time you do not control. Treat it as the first thing to check on any bid where you are not the manufacturer.
