Barrel of fake goods (3)
I believe the answer is:
keg
'barrel' is the definition.
(keg is a kind of barrel)
'of fake goods' is the wordplay.
'of' says the answer is hidden in the clue.
'KEG' can be found hidden inside 'fake goods'.
(Other definitions for keg that I've seen before include "Sort of beer" , "Small cask or barrel" , "Barrel as for beer" , "What's found at King's Head" , "Small beer cask" .)
