Something different: free trade with Peru (9)
I believe the answer is:
departure
'something different' is the definition.
I can't tell whether this definition defines the answer.
'free trade with peru' is the wordplay.
'free' indicates anagramming the letters.
'with' means one lot of letters go next to another.
'trade' after 'peru' is 'perutrade'.
'perutrade' with letters rearranged gives 'DEPARTURE'.
Can you help me to learn more?
(Other definitions for departure that I've seen before include "Act of leaving" , "The act of going away" , "Lucky" , "Exit" , "change of direction" .)
