Bunching of predefined categories has been enabled now for bidding. Buyer can create bunch bid of items from same category. Buyer can also create bunch bid of items from different categories if such categories are enabled for bunching by GeM. If the item categories that you are trying to bunch are not enabled to be bunched together and you feel that these are items are having same Supplier / OEM base and are required to be bought together and bunching will not lead to restriction in competition, then you may please send an email request to GeM at request-bunch@gem.gov.in for enabling bunching of such categories. Please mention exact name of GeM categories that you are requesting for enabling bunching. Your request would be examined by GeM team and if it is found that such bunching would not lead to restrictive bidding, GeM would enable bunching of those categories. This is a one time exercise and once enabled, all buyers can bunch those categories in all their future bids. Custom and BoQ items are by default enabled to be bunched with other regular categories.
