Case of dill imported by fruit vendor (6)
I believe the answer is:
pedlar
'vendor' is the definition.
(pedlar is a kind of vendor)
'case of dill imported by fruit' is the wordplay.
'case of' means to remove the middle letters (outsides of).
'imported by' indicates putting letters inside.
'fruit' becomes 'pear' (pear is a kind of fruit).
'dill' with its centre removed is 'dl'.
'dl' put within 'pear' is 'PEDLAR'.
(Other definitions for pedlar that I've seen before include "Itinerant salesperson" , "Hawker" , "Travelling vendor of small goods" , "Travelling merchant" , "Travelling salesman" .)
