Kitchen appliance right to be included among diverse cargoes (3,6)
I believe the answer is:
gas cooker
'kitchen appliance' is the definition.
(I know that gas cooker is a type of kitchen stove)
'right to be included among diverse cargoes' is the wordplay.
'right' becomes 'OK' (OK can mean right or appropriate).
'to be included among' indicates putting letters inside.
'diverse' is an anagram indicator (diverse implies variety or a change in the letters).
'cargoes' is an anagram of 'gascoer'.
'ok' put within 'gascoer' is 'GAS-COOKER'.
(Other definitions for gas cooker that I've seen before include "Kitchen appliance" , "Type of stove" .)
