Dispatching right goods sold abroad for displays (5)
I believe the answer is:
expos
'for displays' is the definition.
(I've seen this before)
'dispatching right goods sold abroad' is the wordplay.
'dispatching' is a deletion indicator.
'right' becomes 'rt' (abbreviation as in Rt Hon- the Right Honourable).
'goods sold abroad' becomes 'exports' (I've seen this in another clue).
'exports' with 'rt' removed is 'EXPOS'.
(Other definitions for expos that I've seen before include "Public displays" , "International exhibitions" , "International shows" .)
