Standard requirements on application form reversed for wine seller (6)
I believe the answer is:
bodega
'wine seller' is the definition.
(a bodega is a wine shop)
'standard requirements on application form reversed' is the wordplay.
I cannot really see how this works, but
'form' could be 'bod' (synonyms) and 'bod' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
(Other definitions for bodega that I've seen before include "warehouse for wine" , "winestore" , "booze shop" , "Shop or cellar in Spain for selling wine" , "concern for alcohol" .)
