Crew bringing in European import (4)
I believe the answer is:
mean
'import' is the definition.
(I've seen this before)
'crew bringing in european' is the wordplay.
'crew' becomes 'man' (I've seen this before).
'bringing in' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'man' going around 'e' is 'MEAN'.
(Other definitions for mean that I've seen before include "Have in mind to be miserly?" , "Intend, plan" , "mercenary" , "The average could be miserly" , "Despicable" .)
