'freight charge' is the definition.
'cartage' can be an answer for 'freight' (thesaurus). I'm not sure about the 'charge' bit.

'trouble about the label' is the wordplay.
'trouble' becomes 'care'.
'about' is an insertion indicator.
'the label' becomes 'tag' (tag is a kind of label).
'care' placed around 'tag' is 'CARTAGE'.

'take' is the link.
