You cannot add steam codes to a non steam account. it should be all over the product pages for both steam and non steam versions.

Steam is treated as a separate console/license. I know it sounds weird but even though you might have the PC version of FF XIV, if it's not the Steam version, the Steam version of your expansions won't work. I found this out during the Heavensward launch and almost lost money. Thankfully SE refunded me Heavensward and I bought it on Steam.
