Fabric from China ready for Iranian (8)
I believe the answer is:
material
'fabric' is the definition.
(I know that fabric can be written as material)
'china ready for iranian' is the wordplay.
'china' becomes 'mate' (china plate is Cockney rhyming slang for mate).
'ready for iranian' becomes 'rial' (currency of Iran - ready can mean cash).
'mate'+'rial'='MATERIAL'
'from' acts as a link.
(Other definitions for material that I've seen before include "Cloth, fabric" , "I alert ma (anag.)" , "Essential" , "Matter; fabric" , "Directly relevant to a matter, in a law case perhaps" .)
