want to sell Dell products on GeM portal.

We are dealing in computer hardware and software. Now also we are willing to deal in with DELL brand for Desktop Computers and Laptops. I'm filling the Government Tender and its required the authorized letter from company. But I want to sell items through the Government eMarketplace (GEM) portal. I have a GEM ID also. But I need reseller or partner certificate from OEM so that I can add product on GEM portal.

Thanks and Regards,
