Number of goods transported out of France (5)
I believe the answer is:
eight
'number' is the definition.
(eight is a kind of number)
'goods transported out of france' is the wordplay.
'goods transported' becomes 'freight' (I've seen this before).
'out of' suggests deleting specific letters.
'france' becomes 'fr' (abbreviation).
'freight' with 'fr' taken out is 'EIGHT'.
'of' is the link.
(Other definitions for eight that I've seen before include "Oxford crew, perhaps?" , "Half a quarter" , "Crew of racing shell" , "Figure" , "destroyed [IN 8A] here!" .)
